Abstract This paper involves the analysis of the quality of anthropometric data on children under five years of age in two information systems in the State of São Paulo. The sample included 2,117,108 children from the Food and Nutrition Surveillance System (SISVAN), and 748,551 from the State Milk Project (VIVALEITE). Initially, we evaluated the frequency of missing values and others outside the equipment spectrum and calculated the digit-to-weight preference index. After calculating height-for-age (HAZ), weight-for-age (WAZ), and body mass index-for-age (BAZ), we flagged the biologically implausible values (BIV) and calculated the standard deviation (SD). For each municipality, we calculated the mean and the SD of HAZ, WAZ, and BAZ; and plotted the SD values as a function of the mean. The digit-to-weight preference index was greater among children aged between 24 and 59 months in SISVAN. The frequency of BIV for HAZ (SISVAN 2.56%; VIVALEITE 0.98%) was higher than for WAZ (SISVAN 2.10%; VIVALEITE 0.18%). For HAZ, variations among municipalities were more pronounced in VIVALEITE than in SISVAN. The height variable presents low reliability in both systems. The weight variable reveals satisfactory quality in VIVALEITE and unsatisfactory quality in SISVAN. Paulo 2117108 2 117 108 2,117,10 SISVAN, SISVAN , (SISVAN) 748551 748 551 748,55 VIVALEITE. .

Resumo O objetivo foi analisar a qualidade dos dados antropométricos de crianças menores de cinco anos em dois sistemas de informação no estado de São Paulo. A amostra compreendeu 2.117.108 crianças do Sistema de Vigilância Alimentar e Nutricional (Sisvan) e 748.551 do Projeto Estadual do Leite (Vivaleite). Inicialmente, avaliamos a frequência de valores faltantes e fora do espectro do equipamento, e calculamos o índice de preferência de dígito para peso. Após calcular os índices de altura para idade (A-I), peso para idade (P-I) e índice de massa corporal para idade (IMC-I), identificamos os valores biologicamente implausíveis (VBI) e calculamos o desvio-padrão (DP). Para cada município, calculamos a média e o DP de A-I, P-I e IMC-I; e plotamos os valores de DP em função da média. A preferência de dígito no peso foi maior em crianças de 24 a 59 meses no Sisvan. A frequência de VBI para A-I (SISVAN 2,56%; Vivaleite 0,98%) foi maior do que para P-I (Sisvan 2,10%; Vivaleite 0,18%). Para o índice A-I as variações entre os municípios foram mais acentuadas no Vivaleite do que no Sisvan. A variável altura apresentou baixa confiabilidade nos dois sistemas. A variável peso apresentou qualidade satisfatória no Vivaleite e insatisfatória no Sisvan. Paulo 2117108 2 117 108 2.117.10 Sisvan 748551 748 551 748.55 Vivaleite. .

Abstract Dairy production in Ecuador is a source of economic income for many small and medium producers, however the lack of technical advice leads to problems in the quality of milk, and affects their production volume. The purpose of this investigation was to conduct a pilot plan to improve the quality of milk produced by 57 small producers from different parishes of the cantons of Quito, Rumiñahui and San Miguel de los Bancos in the province of Pichincha, through a training plan in good milking practices and feeding strategies. Two initial samplings were carried out (between October and November 2021) prior to the training, and two final samplings (in June 2022) to measure the impact of the training. A total of 1.273 samples were collected, of these only 4.02 % (52/1273) (of the samples) complied with the reference values of the national regulations, while 95.98 % (1243/1273) did not comply with any of the evaluated parameters; however, the vast majority of the milk is suitable for human consumption, yet its nutritional quality needs to be improved. We were able to reduce considerably (although not statistically) the somatic cell count (SC, from an initial average of 623530 CS ml-1 to 365660 CS ml-1 after training, being correlated with the significant increase in the percentage of lactose between the initial and final sampling; there were also significant differences in the percentage of fat and total solids, although in these two cases their values decreased after training (fat from 2.58 % in the initial sampling to 2.10 % in the final sampling and total solids of 11, 44 % to 11.00 %);showed no significant differences between samples. It is concluded that the training was beneficial since the considerable decrease in the somatic cell count increased the volume of milk production of the small producers, and therefore their economic income. For the rest of the parameters, it is recommended to reinforce training in nutrition, feeding, pasture management, etc., in order to increase their values, as well as to maintain constant training programs for producers, supported by academia, private and public entities.

Resumen La producción láctea en Ecuador es una fuente de ingresos económicos para muchos pequeños y medianos productores; sin embargo, la falta de asesoría técnica conlleva a que tengan problemas en la calidad de la leche y se vea afectado su volumen de producción, por lo que la presente investigación tuvo como finalidad realizar un plan piloto para el mejoramiento de la calidad de leche producida por 57 pequeños productores de diferentes parroquias de los cantones Quito, Rumiñahui y San Miguel de los Bancos de la provincia de Pichincha, mediante un plan de capacitación en buenas prácticas de ordeño y estrategias de alimentación. Se realizaron 2 muestreos iniciales (entre octubre y noviembre de 2021), previo a la capacitación, y 2 muestreos finales (en junio de 2022) para medir el impacto de estas. Se recolectaron 1.273 muestras, donde solamente el 4,02 % (52/1.273) de las mismas, cumplen con los valores referenciales de la normativa nacional, mientras que el 95,98 % (1.243/1.273) no cumple con alguno de los parámetros evaluados; sin embargo, la gran mayoría de dicha leche sí es apta para el consumo humano, pero requiere ser mejorada en su calidad nutricional. Se logró disminuir considerablemente (aunque no estadísticamente) el conteo de células somáticas, de un promedio inicial de 623.530 CS ml-1 a 365.660 CS ml-1 luego de la capacitación, siendo correlacionado con el aumento significativo del porcentaje de lactosa entre el muestreo inicial y el final; también existió diferencias significativas en el porcentaje de grasa y sólidos totales, aunque en estos dos casos disminuyeron sus valores luego de la capacitación (grasa de 2,58 % en el muestreo inicial a 2,10 % en el final y sólidos totales de 11,44 % a 11,00 %). El resto de los parámetros no mostraron diferencias significativas entre los muestreos. Se concluye que la capacitación fue beneficiosa, pues la disminución considerable del conteo de células somáticas aumentó el volumen de producción de leche de los pequeños productores y, por ende, sus ingresos económicos. Para el resto de los parámetros se recomienda reforzar las capacitaciones de nutrición, alimentación, manejo de pasturas, etc., para incrementar sus valores, así como mantener constantes programas de capacitación a los productores, apoyados desde la academia, la empresa privada y entidades públicas.

Abstract The objective was to know the population structure of Holstein animals in the family dairy system, to identify possible origins of the genetic material, to know the degree of inbreeding and to identify possible traces of selection in the genome, which allow glimpses of the traits that have been improved over the years. The study included 270 animals genotyped with the GGP-50K® chip. After genotype quality control, 43,548 autosomal SNPs were included. To know the population structure, analyses of mixtures and principal components (PCs) were performed. To know genomic inbreeding and detect traces of selection, information on runs of homozygosity (ROH) was used. Mixture analysis was performed with the Admixture software, and PC, ROH and inbreeding analyses were performed with SVS-v7.6.8. Mixture analysis showed evidence of six components, all linked to Holstein bulls families with different country of origin. The PCs did not show stratification of the population by herd. The mean inbreeding coefficient was 0.59 ± 0.53 %. In the regions of the genome with ROHs most frequent in the population (≥20 animals), numerous associations, QTLs and genes related to milk production and composition, fertility parameters, susceptibility to diseases, body conformation, feed efficiency and some characteristics of carcass composition have been reported. The results reflect the existence of a wide genetic diversity in this population and the possibility of carrying out genetic improvement work through selection without affecting inbreeding levels.

Resumen El objetivo fue conocer la estructura poblacional de los animales Holstein del sistema de lechería familiar, identificar posibles orígenes del material genético, conocer el grado de consanguinidad e identificar posibles huellas de selección en el genoma, que permitan vislumbrar las características que se han mejorado a través de los años. El estudio incluyó 270 animales genotipados con el chip GGP-50K®. Después del control de calidad de genotipos, se incluyeron 43,548 SNP autosómicos. Para conocer la estructura poblacional se realizaron análisis de mezclas y componentes principales (CP). Para conocer la consanguinidad genómica y detectar huellas de selección, se usó información de corridas de homocigosidad (ROH). El análisis de mezclas se realizó con el software Admixture, y los de CP, ROH y consanguinidad se realizaron con SVS-v7.6.8. El análisis de mezclas mostró evidencia de seis componentes, todos ligados a familias de sementales Holstein con diferente país de origen. Los CP no evidenciaron estratificación de la población por hato. El coeficiente de consanguinidad promedio fue de 0.59 ± 0.53 %. En las regiones del genoma con ROH más frecuentes en la población (≥20 animales), se han reportado numerosas asociaciones, QTL y genes relacionados con producción y composición de la leche, parámetros de fertilidad, susceptibilidad a enfermedades, conformación corporal, eficiencia alimenticia y algunas características de composición de la canal. Los resultados reflejan la existencia de una amplia diversidad genética en esta población y la posibilidad de realizar trabajos de mejoramiento genético a través de selección sin afectar los niveles de consanguinidad.

ABSTRACT Due to the diversification of dairy products developed in the state of Falcón, the introduction of a fermented dairy product derived from yogurt combined with Aloe vera gel, a traditional crop of the region, is novel due to its nutritional properties and health benefits. The objective of this research was to evaluate the quality of a dairy drink with fermented aloe according to current regulations. Important authors such as Tamime and Robinson 1, Morillo and Toyo 2, Méndez and Romero 3 were taken as references. Product elaboration runs were carried out on a laboratory scale, in order to establish the adequate proportions of the fruity Aloe gel by mixing fruit pulp, sugar and Aloe gel, the most accepted being the 1:1:1 ratio. The physicochemical and microbiological characterization of the raw material and the finished product was carried out using the COVENIN standards and organoleptic tests to untrained judges to ensure the acceptance of the product, from which a fermented milk drink was obtained with the addition of 50 % gel of Fruity Aloe with a pH of 4,51; a titratable acidity of 0,837 % lactic acid; 3,64 % fat and 12,92 % non-fat solids. Regarding the microbiological quality, few yeasts and the absence of coliform bacteria were found, which complies with the physicochemical and microbiological requirements demanded by the regulations, allowing the obtaining of a quality product suitable for human consumption based on natural raw materials.

Esta investigación tuvo como objetivo evaluar la calidad de una bebida láctea fermentada con gel de Aloe frutado según la normativa vigente. Se tomaron como referencias importantes autores como Tamime y Robinson, (1) Morillo y Toyo, (2) Méndez y Romero. (3) Se realizaron corridas de elaboración del producto a escala de laboratorio, a fin de establecer las proporciones adecuadas del gel de Aloe frutado mezclando pulpa de fruta, azúcar y gel de Aloe, siendo la más aceptada la proporción 1:1:1. Se realizó la caracterización fisicoquímica y microbiológica de la materia prima y del producto terminado mediante las normas COVENIN y pruebas organolépticas a 10 jueces no entrenados para asegurar la aceptación del producto, de donde se obtuvo una bebida láctea fermentada con la adición de 50 % de gel de Aloe frutado con un pH de 4,51; una acidez titulable de 0,837 % de ácido láctico; 3,64 % de grasa y 12,92 % de sólidos no grasos. Respecto a la calidad microbiológica se encontraron levaduras escasas y ausencia de bacterias coliformes, con lo cual se cumple con los requisitos fisicoquímicos y microbiológicos exigidos por la normativa, permitiendo la obtención de un producto de calidad apto para el consumo humano a base de materias primas naturales.

ABSTRACT The paper analyzes the quality of the water supplied by the potable water treatment plant Altos of Quintero to the city of Santiago de Cuba through the study of five consumers. The quality of the parameters analyzed was determined for pH, color, turbidity, residual free chlorine and determination of total and fecal coliforms, resulting in La Colonia, La Cervecería Hatuey and the Combined Milk, which residual free chlorine and turbidity are outside the norm in some occasions. The effects of the quality of drinking water coming from the potabilizer were mainly the deterioration of the infrastructure of the supply networks and poor storage conditions of the liquid in the above mentioned institutions. Options are presented to ensure that water quality is maintained in the different consumption centers and a predictable model is proposed that allows the maximum time that guarantees the minimum level of allowable residual chlorine that a consumer source should have.

RESUMEN El trabajo analiza la calidad del agua que suministra la potabilizadora Altos de Quintero a la ciudad de Santiago de Cuba mediante el estudio de cinco consumidores. Al agua de los seis centros analizados se les determinó su calidad por la medición de los parámetros: pH, color, turbidez, cloro libre residual y determinación de coliformes totales y fecales, resultando La Colonia, La Cervecería Hatuey y el Combinado Lácteo las entidades en las cuales el cloro libre residual y la turbidez se encuentran fuera de norma en algunas ocasiones. Las afectaciones de la calidad del agua potable procedente de la potabilizadora se deben fundamentalmente al deterioro de la infraestructura de las redes de abastecimiento y a las malas condiciones de almacenamiento del líquido en las instituciones antes mencionadas. Se presentan opciones para garantizar que se mantenga la calidad del agua en los diferentes centros de consumo y se propone un modelo predictivo que posibilita determinar el tiempo máximo que garantiza el mínimo nivel de cloro residual libre permisible que debe disponer una fuente consumidora.

Abstract Undernutrition occurs when there is poor intake or assimilation of energy and nutrients. If undernutrition is established within the first years of life, the health consequences are devastating. Early treatment of undernutrition is critical to reduce these consequences and milk plays an important role in this treatment. Cow's milk is an excellent food due to the content and quality of its macro- and micronutrients. This has led to a steady increase in research and the use of milk in treating undernutrition since the beginning of the 20th century. In Chile, child undernutrition was practically eradicated between the decades of 1960 and 1980 due to the successful application of maternal and child public policies, within which the product Leche Purita was fundamental. However, the history of milk as part of nutritional policies in Chile began much earlier. Commemorating fifty years since the introduction of Leche Purita, we aim to summarize the historical importance of milk in Chile's nutritional policies. We emphasize Leche Purita's role in eradicating child undernutrition and reducing anemia among children.

Resumen La desnutrición ocurre cuando hay una ingesta o asimilación deficiente de la energía y los nutrientes. Si esta se produce dentro de los primeros años de vida, las consecuencias para la salud son devastadoras. El tratamiento temprano de la desnutrición es clave para reducir estas consecuencias y en este proceso la leche tiene una participación destacada. La leche es un excelente alimento debido al contenido y calidad de sus macro- y micronutrientes, lo que ha llevado a que la investigación y el uso de la leche en el tratamiento de la desnutrición hayan aumentado sostenidamente desde comienzos del siglo XX. En Chile, la desnutrición infantil fue prácticamente erradicada entre los años 1960 y 1980 debido a la aplicación exitosa de una serie de políticas públicas materno-infantiles, dentro de las cuales la Leche Purita fue fundamental. Sin embargo, la historia de la leche como parte de las políticas nutricionales en Chile comenzó mucho antes. Conmemorando los cincuenta años desde el nacimiento de Leche Purita, el objetivo de este trabajo es realizar un breve repaso acerca de la importancia histórica de la leche en las políticas nutricionales en Chile, enfatizando la contribución realizada por la Leche Purita a la erradicación de la desnutrición infantil y a la disminución de la anemia en niños.

Abstract The effect of using alpaca milk on the physicochemical, composition, microbiological and sensory attributes of artisanal whipped yogurt with different alpaca and cow milk formulations was evaluated. The pasteurized process methodology to obtain seven formulations of yogurt with alpaca milk was subjected to physicochemical, composition, microbiological and sensory quality analysis with the following results: The physicochemical quality of yogurt made with different proportions of alpaca milk was favorable for the stability of the yogurt, also denoting a greater richness of total solids in its useful life period of consumption. The composition of yogurts with a different proportion of alpaca milk increases the nutritional components of yogurt, enriching it with natural nutrients, improving the quality of yogurt and promoting it as a “concentrated fermented milk.” The microbiological quality of yogurts made with various proportional parts of alpaca milk appears acceptable for consumption of yogurt according to the Peruvian Technical Standards for milk and dairy derivatives, given the absence of pathogenic microorganisms, minimal presentation of fungi and yeasts and presence initial acid lactobacilli, which inhibit bacterial growth and reduce bacterial presence at the time of final ripening of the yogurt. Finally, the sensory quality of the yogurts prepared with partial use of alpaca milk demonstrated to have good flavor, aroma and smell characteristics, mainly in those whose formulation uses majority proportions of alpaca milk, giving rise to products with acceptable tastes for the consumer.

Resumen Se evaluó el efecto del uso de leche de alpaca sobre los atributos fisicoquímicos, composición, microbiológico y sensorial del yogur batido artesanal con diferente formulación de leche de alpaca y vaca. La metodología de proceso pasteurizado para obtener siete formulaciones de yogurt con leche de alpaca, fueron sometidos al análisis fisicoquímico, composición, microbiológico y de calidad sensorial con resultados siguientes: La calidad fisicoquímica del yogurt elaborado con proporciones distintas de leche de alpaca resulto favorable para la estabilidad del yogurt, denotando también una mayor riqueza de solidos totales en su periodo de vida útil de consumo. La composición de los yogures con diversa proporción de leche de alpaca aumenta los componentes nutritivos del yogurt, enriqueciéndolo con nutrientes naturales, mejorando la calidad del yogurt y promoviéndola, como una “leche fermentada concentrada”. La calidad microbiológica de los yogures elaborados con partes proporcionales diversas de leche de alpaca, aparece aceptable para el consumo del yogurt según las Normas Técnicas Peruanas para la leche y derivados lácteos, dada la ausencia de microorganismos patógenos, mínima presentación de hongos y levaduras y presencia inicial de lactobacilos ácidos, que inhiben el crecimiento bacteriano y disminuyen presencia bacteriana al momento de maduración final del yogurt. Finalmente, la calidad sensorial de los yogures preparados con uso parcial de leche de alpaca demostró tener buenas características de sabor aroma y olor, principalmente en aquellos cuya formulación hace uso de proporciones mayoritarias de leche de alpaca, dando lugar a productos de gustos aceptables para el consumo.

Abstract Objective To carry out a narrative review on the use of marketing strategies in child nutrition, as well as potential implications for health professionals and children. Data source Searches were carried out on the PubMed, SciELO, and Google platforms, using the terms “child nutrition” or “industrialized baby food” or “infant formula” or “breast milk” or “breastfeeding” and “marketing”, with original articles, review articles, institutional reports, institutional position documents and websites considered relevant to the topic being analyzed. Data synthesis Children's food marketing started with the industrialization of food and the resulting actions aimed at increasing sales and meeting commercial interests. Since its inception to the present, infant formulas have been the most widely used products, which has impacted breastfeeding practices. International and national institutions, that care for children's health, are searching for strategies to limit the abusive marketing of industrialized children's foods. Marketing strategies interfere with medical knowledge and actions, potentially influencing the guidance provided by pediatricians to families, and finally, compromising healthy eating practices at a critical period in life, with possible long-term effects. Conclusions Health professionals, especially pediatricians, must provide the best care for children and families, and need to maintain the search for quality scientific information, not influenced by conflicts of interest. Updated and critical knowledge on the part of healthcare professionals can curb marketing strategies that aim to influence their actions. nutrition PubMed SciELO platforms formula breast milk “breastfeeding marketing, , “marketing” articles reports analyzed Childrens Children s interests present products institutions childrens foods families finally life longterm long term effects information interest “marketing

Resumo A presença de bactérias patogênicas em alimentos é considerada a principal causa de doenças transmitidas por alimentos e deterioração da qualidade dos alimentos em todo o mundo. O presente estudo teve como objetivo determinar a eficácia de cinco óleos essenciais (OEs) contra patógenos de origem alimentar multirresistentes. No presente estudo, bactérias Gram-negativas (Escherichia, Enterobacter, Citrobacter, Proteus, Pseudomonas e Klebsiella) e as bactérias Gram-positivas Staphylococcus foram isoladas do leite cru e caracterizadas bioquimicamente. O efeito antibacteriano de diferentes antibióticos e OEs (tomilho, orégano, capim-limão, hortelã e alecrim) foi determinado usando o método padrão de difusão em disco. O estudo do antibiograma revelou que as bactérias Gram-negativas eram altamente resistentes à penicilina, enquanto o Staphylococcus era resistente à estreptomicina, amoxicilina e lincomicina. Foi observada resistência moderada à doxiciclina, amicacina, enrofloxacina, canamicina e cefixima. Os isolados foram encontrados menos resistentes à gentamicina, cloranfenicol e ciprofloxacina. Os OEs mostraram uma ampla gama de atividade antimicrobiana contra todas as bactérias, exceto P. aeruginosa. Destes, o tomilho foi mais eficaz contra a maioria das cepas bacterianas multirresistentes e formou a maior zona de inibição (26 mm) contra Escherichia seguido de óleo de orégano (18 mm) contra Staphylococcus (p<0,05). Klebsiella spp e Citrobacter spp apresentaram resistência ao óleo de menta e capim-limão, respectivamente. Os OEs como capim-limão, hortelã e alecrim foram menos ativos contra todas as bactérias. Os resultados do estudo recente sugerem o uso de OEs como agentes antibacterianos naturais para conservação de alimentos.

Abstract The presence of pathogenic bacteria in food is considered as a primary cause of food-borne illness and food quality deterioration worldwide. The present study aimed to determine the effectiveness of five essential oils (EOs) against multidrug-resistant foodborne pathogens. In the current study Gram-negative bacteria (Escherichia, Enterobacter, Citrobacter, Proteus, Pseudomonas, and Klebsiella) and the Gram-positive bacteria Staphylococcus were isolated from raw milk and biochemically characterized. The anti-bacterial effect of different antibiotics and EOs (thyme, oregano, lemongrass, mint, and rosemary) was determined using the standard disc diffusion method. The antibiogram study revealed that Gram-negative bacteria were highly resistant to penicillin while Staphylococcus was resistant to streptomycin, amoxicillin, and lincomycin. Moderate resistance was observed to doxycycline, amikacin, enrofloxacin, kanamycin and cefixime. Isolates were found less resistant to gentamycin, chloramphenicol, and ciprofloxacin. EOs showed a broad range of antimicrobial activity against all bacteria except P. aeruginosa. Of these, thyme was more effective against most of the multi-drug resistant bacterial strains and formed the largest zone of inhibition (26 mm) against Escherichia followed by oregano oil (18 mm) against Staphylococcus (p<0.05). Klebsiella spp and Citrobacter spp showed resistance to mint and lemongrass oil respectively. The EOs such as lemongrass, mint and rosemary were less active against all the bacteria. The findings of the recent study suggest the use of EOs as natural antibacterial agents for food preservation.

Resumo O artigo objetiva identificar infrações à NBCAL e analisar o conteúdo das mensagens postadas na rede social Instagram. Estudo de abordagem quali-quantitativa, com amostra de conveniência composta por perfis identificados por meio de termos específicos, precedidos do símbolo hashtag (#). A coleta de dados foi realizada durante dois meses por pesquisadores treinados, por meio de questionário estruturado. Calculou-se a frequência de promoção de produtos que caracterizava violação à NBCAL, segundo categoria e fabricante. As mensagens foram analisadas por meio da técnica de análise de conteúdo. Foram identificadas 64 contas pessoais de mulheres mães com infrações em 89 produtos, a maioria alimentos (n = 72), sendo os compostos lácteos (54,2%) e as fórmulas infantis para lactentes (45,8%) os mais divulgados. Duas categorias temáticas emergiram dos textos postados, uma relativa à qualidade dos produtos e a outra sobre a dificuldade com a amamentação, especialmente a baixa produção de leite. O estudo identificou violações à NBCAL na rede social Instagram, alertando para a necessidade do reconhecimento do marketing digital para incluí-lo nas regras impostas pela norma no contexto virtual, considerando a capilaridade das redes sociais na divulgação de informações para o público em questão.

Abstract The article aims to identify NBCAL violations and analyze the content of messages posted on the Instagram social network. This qualitative-quantitative study consisted of a convenience sample of profiles identified through specific terms preceded by the hashtag symbol (#). Data were collected for two months by trained researchers using a structured questionnaire. We calculated the product promotion frequency that characterized violation of the NBCAL per category and manufacturer. The messages were analyzed using the content analysis technique. We identified 64 personal accounts of mothers with violations in 89 products, mainly food (n = 72), dairy compounds (54.2%), and infant formulas (45.8%) were the most publicized. Two thematic categories emerged from the posted texts, one related to the quality of the products and the other about breastfeeding difficulty, especially low milk production. The study identified NBCAL violations on the Instagram social network, alerting the need to recognize digital marketing to include it in the rules imposed by the Norm in the virtual context, considering the capillarity of social networks in disseminating information to the public in question.

This study sought to explore the effect of the administration of long-term, exogenous oxytocin on buffalo milk. In this study, newly-calved postpartum buffaloes (Nili-Ravi) (n = 24) were divided equally into three groups: (control without oxytocin - CON, 10 i.u. oxytocin - LOW, 30 i.u. oxytocin - HIGH). Oxytocin was injected twice a day before each 154-day milking. Milk production, milk composition, somatic cell counts, and progesterone (P4) were evaluated daily, weekly, and fortnightly, respectively. Results revealed that the HIGH group produced high milk production and pH values, but lower milk density than the CON and LOW groups. The HIGH group and LOW group had higher milk fat and solid-not-fat (SNF) compared to the CON group. SNF and protein were higher in the LOW group than the CON group. Freezing point, lactose, solids, somatic cell count, and P4 were similar in all three groups. Overall, it can be concluded that long-term, exogenous oxytocin has a positive effect on milk production, fat, SNF, and protein, with a negative effect on milk pH. None of the oxytocin treatments affected somatic cell counts and P4 concentration in postpartum buffalo milk.

Abstract Objective: To characterize the performance of some productive indicators of Murciano-Granadina goats under post-quarantine conditions in western Cuba. Materials and Methods: To evaluate the production and quality of milk, 10 lactating females and 12 kids of their offspring were selected during a period of 30 days. The quality indicators were: density, fat, nonfat solids, acidity and reductase. A semi-intensive production system was established, with controlled grazing and feeding trough supplementation with the protein forage plant Cratylia argentea (Desvaux O. Kuntze). Results: Survival of 97,4 % and 1,2 kids per birth were obtained during the study. Birth weight of the kids was 1,7 kg and daily gain was 0,08 kg. Average daily milk production was higher than 1,4 kg/goat. Conclusions: The analysis of the evaluated indicators allowed the characterization of the productive performance of the first genetic nucleus of Murciano-Granadina breed goats established in Cuba. In addition, the production and quality of milk produced by these goats comply with the genetic potential of this breed.

Se estableció un sistema productivo semintensivo, con pastoreo controlado y complementación en canoa con la planta forrajera proteica Cratylia argentea (Desvaux O. Kuntze). Resultados: Se obtuvo supervivencia de 97,4 % y 1,2 cabrito por parto durante el estudio. El peso del cabrito al nacer fue de 1,7 kg y la ganancia diaria de 0,08 kg. La producción de leche promedio diaria fue superior a 1,4 kg/cabra. Conclusiones: El análisis de los indicadores evaluados permitió la caracterización del comportamiento productivo del primer núcleo genético de cabras de la raza Murciano-Granadina establecido en Cuba. Además, la producción y la calidad de la leche producida por estas cabras cumplen con el potencial genético de esta raza.

Abstract Objective: To evaluate the response of Cenchrus clandestinus (Hochst. ex Chiov.) Morrone to fertilization by nutrient extraction rate, residual height and defoliation timing in the Colombian high tropics. Materials and Methods: Two residual heights (6 and 12 cm) and four fertilization doses were evaluated in plots that were cut with four, five or six live leaves. Agronomic response was evaluated during one year and chemical composition during the months of highest and lowest rainfall. The information was analyzed using a spatially and temporally divided-plot design with three replications. Results: The growth of C. clandestinus was superior when harvested with five leaves and 6-cm residual height in the dry season, and six leaves and 6 cm residual height or five leaves and 12 cm residual height in the rainy season. The nutritional quality of C. clandestinus was higher when it was harvested with greater residual height or when doses of 648 kg N/ha and 114 kg P/ha were used. In addition, it was higher when the plant showed four live leaves in the dry season, but similar in the rainy season. Conclusion: The moment to obtain the maximum growth rate of C. clandestinus depends on the time and residual height of harvest. In addition, higher efficiency is achieved in this forage when edaphic fertilization is applied during the rainy season.

Morrone a la fertilización mediante la tasa de extracción de nutrientes, la altura residual y el momento de defoliación en el trópico alto colombiano. Materiales y Métodos: Se evaluaron dos alturas residuales (6 y 12 cm) y cuatro dosis de fertilización en parcelas que se cortaron con cuatro, cinco o seis hojas vivas. La respuesta agronómica se evaluó durante un año y la composición química durante los meses de mayor y menor precipitación. La información se analizó mediante un diseño de parcelas divididas en el espacio y el tiempo, con tres repeticiones. Resultados: El crecimiento de C. clandestinus fue superior cuando se cosechó con cinco hojas y altura residual de 6 cm, en la época seca, y seis hojas y 6 cm de altura residual o cinco hojas y 12 cm de altura residual, en la época de lluvias. La calidad nutricional de C. clandestinus fue mayor cuando se cosechó con mayor altura residual o se utilizó dosis de 648 kg de N/ha y 114 kg de P/ha. Además, fue superior cuando la planta presentó cuatro hojas vivas en la época seca, pero similar en la época de lluvias. Conclusión: El momento para obtener la máxima tasa de crecimiento de C. clandestinus depende de la época y la altura residual de la cosecha. Además, se logra mayor eficiencia en este forraje cuando la fertilización edáfica se aplica durante la época de lluvia.

Abstract Roquefort and Canastra cheese are products of animal origin with Geographical Identification recognition. They are made with raw milk in a centuries-old traditional production. To protect the unique identity and quality of products such as these, treaties and agreements have been passed in the international community. At the same time, a debate revolves around food safety due to the use of milk without heat treatment, which creates barriers to commercialization. Thus, international health standards, internalized in the legislation of the signatory countries, must be applied to traditional production, sometimes with adaptations. This study aimed to promote a non-systematic review, analyzing the content of commercial and health international treaties, agreements, and norms, and the Brazilian and French/European Union legislation, to evaluate the robustness of the foreseen regulation processes. It concluded that the surveyed documents have a comprehensive potential for the qualitative and sanitary protection of the products by implementing guarantees that are conditioned to the applicability of theory to practice in manufacturing, registering, and inspecting production in the evaluated countries and considering the need of consumption alerts for vulnerable population groups.

Resumo Os queijos roquefort e canastra são produtos de origem animal com reconhecimento de identificação geográfica, fabricados com leite cru por meio de modos de produção centenários. Para proteção da identidade e qualidade únicas de produtos como esses, tratados e acordos foram celebrados na comunidade internacional. Ao mesmo tempo, há um debate quanto à segurança sanitária deles devido à utilização de leite sem processamento térmico, o que gera barreiras à sua comercialização, existindo normas sanitárias internacionais internalizadas na legislação dos países signatários que devem ser aplicadas à produção tradicional, mesmo que às vezes com adaptações. Este trabalho teve por objetivo promover uma revisão não sistemática ao analisar o conteúdo de tratados, acordos e normas internacionais, comerciais e sanitárias, além das legislações brasileira, francesa e da União Europeia, a fim de verificar a robustez dos processos de regulação previstos. Concluiu-se que os documentos levantados têm potencial abrangente para a proteção qualitativa e sanitária dos produtos elencados, ficando a concretização dessas garantias a cargo da aplicabilidade da teoria nos processos de fabricação, registro, fiscalização e inspeção dos países, não menosprezando a necessidade de alerta para grupos vulneráveis da população sobre o consumo desses produtos.

Resumo O objetivo foi analisar a qualidade dos dados antropométricos de crianças menores de cinco anos em dois sistemas de informação no estado de São Paulo. A amostra compreendeu 2.117.108 crianças do Sistema de Vigilância Alimentar e Nutricional (Sisvan) e 748.551 do Projeto Estadual do Leite (Vivaleite). Inicialmente, avaliamos a frequência de valores faltantes e fora do espectro do equipamento, e calculamos o índice de preferência de dígito para peso. Após calcular os índices de altura para idade (A-I), peso para idade (P-I) e índice de massa corporal para idade (IMC-I), identificamos os valores biologicamente implausíveis (VBI) e calculamos o desvio-padrão (DP). Para cada município, calculamos a média e o DP de A-I, P-I e IMC-I; e plotamos os valores de DP em função da média. A preferência de dígito no peso foi maior em crianças de 24 a 59 meses no Sisvan. A frequência de VBI para A-I (SISVAN 2,56%; Vivaleite 0,98%) foi maior do que para P-I (Sisvan 2,10%; Vivaleite 0,18%). Para o índice A-I as variações entre os municípios foram mais acentuadas no Vivaleite do que no Sisvan. A variável altura apresentou baixa confiabilidade nos dois sistemas. A variável peso apresentou qualidade satisfatória no Vivaleite e insatisfatória no Sisvan.

Abstract This paper involves the analysis of the quality of anthropometric data on children under five years of age in two information systems in the State of São Paulo. The sample included 2,117,108 children from the Food and Nutrition Surveillance System (SISVAN), and 748,551 from the State Milk Project (VIVALEITE). Initially, we evaluated the frequency of missing values and others outside the equipment spectrum and calculated the digit-to-weight preference index. After calculating height-for-age (HAZ), weight-for-age (WAZ), and body mass index-for-age (BAZ), we flagged the biologically implausible values (BIV) and calculated the standard deviation (SD). For each municipality, we calculated the mean and the SD of HAZ, WAZ, and BAZ; and plotted the SD values as a function of the mean. The digit-to-weight preference index was greater among children aged between 24 and 59 months in SISVAN. The frequency of BIV for HAZ (SISVAN 2.56%; VIVALEITE 0.98%) was higher than for WAZ (SISVAN 2.10%; VIVALEITE 0.18%). For HAZ, variations among municipalities were more pronounced in VIVALEITE than in SISVAN. The height variable presents low reliability in both systems. The weight variable reveals satisfactory quality in VIVALEITE and unsatisfactory quality in SISVAN.
