RESUMO A adaptação edafoclimática das variedades e/ou clones de cana-de-açúcar pode garantir maior produtividade de forragem para a alimentação animal. Para tanto, foi elaborado um experimento no campus de Seropédica da Universidade Federal Rural do Rio de Janeiro, para avaliação de duas variedades (RB867515 e RB969017) e dois clones (RB058046 e RB098022) de cana-de-açúcar, sob um delineamento de blocos casualizados, com sete repetições. Foram avaliadas variáveis biométricas, perfilhos m-1, índice de área foliar (IAF), Grau Brix e índice de maturação (IM), além das produtividades de forragem e total durante o cultivo do ciclo de cana-planta. O plantio foi realizado em 08/10/2018 e a colheita em 13/09/2019, aos 323 dias após plantio (DAP). Os dados foram analisados pelo software R, sob blocos ao acaso, e medidas repetidas no tempo para as variáveis biométricas, perfilhos m-1, IAF, Grau Brix e IM. As médias foram comparadas pelo teste Tukey (p < 0,10). O clone RB098022 apresentou 20,2% mais perfilhos m-1 que ambas as variedades. Aos 296 DAP ambos os clones e a variedade RB969017 apresentaram IM maiores que 0,85, caracterizando-os como de ciclo mais precoce do que a variedade RB867515 (IM = 0,91 aos 323 DAP). Maiores produtividades e semelhantes de forragem e total foram verificadas para o clone RB098022 e a variedade RB867515 (médias de 141,6 e 151,2 Mg ha-1, respectivamente). Todos os materiais genéticos se adaptaram às condições edafoclimáticas durante o cultivo decana-planta, sendo recomendado a utilização do clone RB098022 e da variedade RB867515 para a alimentação animal na região da Baixada Fluminense. Todos os materiais genéticos se adaptaram às condições edafoclimáticas durante o cultivo decana-planta, sendo recomendado a utilização do clone RB098022 e da variedade RB867515 para a alimentação animal na região da Baixada Fluminense.

ABSTRACT The edaphoclimatic adaptation of sugarcane varieties and clones can ensure higher forage productivity for animal feed. An experiment was conducted at the Seropédica campus of the Federal Rural University of Rio de Janeiro for the evaluation of two varieties (RB867515 and RB969017) and two clones (RB058046 and RB098022) of sugarcane under a randomized block design with seven replications. Biometric variables, tillers m-1, leaf area index (LAI), Brix degree, maturation index (MI), as well as forage and total yields, were evaluated during the cultivation of the sugarcane-plant cycle. Sugarcanes were planted on 10/08/2018 and harvested on 09/13/2019, totaling 323 days after planting (DAP). The data were analyzed using the R software, under randomized blocks and repeated measurements in time for biometric variables, tillers m-1, LAI, Brix Degree and MI. Means were compared using the Tukey test (p < 0.10). Clone RB098022 presented 20.2% more tillers m-1 than both the other varieties. At 296 DAP, both clones and the variety RB969017 presented MI higher than 0.85, indicating them as an earlier cycle than the variety RB867515 (MI = 0.91 to 323 DAP). Higher and similar forage and total yields were obtained with clone RB098022 and variety RB867515 (means 141.6 and 151.2 Mg ha-1, respectively). All sugarcanes adapted to edaphoclimatic conditions during plant cane cultivation, and it is recommended to use the clone RB098022 and the variety RB867515 for animal feed in the Baixada Fluminense region.

Resumo Introdução A tuberculose, caracterizada pela Organização Mundial de Saúde (OMS) como emergência sanitária mundial, é uma doença de impacto global. Objetivo Realizar série histórica de casos de tuberculose em um período de 17 anos em Ouro Preto, Minas Gerais, considerando a histórica relação da doença com a mineração. Método Dados foram obtidos em sistema próprio de registros do município, por busca ativa em prontuários médicos e comparados à quantidade de casos notificados no Sistema de Informação de Agravos de Notificação (SINAN). Para análises de tendência, foram utilizados modelos de regressão polinomial para séries históricas. Resultados Idade média dos casos foi 40,3 ± 16,4 anos. Homens apresentaram 2,23 vezes mais casos e chance 2,07 vezes maior para desfechos negativos. A forma mais observada foi pulmonar (84%), e sorologia para HIV foi realizada em apenas 16,3% dos registros. Principal desfecho observado foi cura (70%), e desfechos negativos totalizaram 20,2% dos registros. Taxa de incidência média foi 29,76 e 16,23 casos/100 mil habitantes na área municipal e distrital, respectivamente. Conclusão Apesar da relação histórica entre mineração e tuberculose no município, observa-se que este ainda apresenta preocupantes vulnerabilidades em relação à vigilância da doença. Análise de série temporal sugeriu declínio na proporção de casos curados entre 2009 e 2015.

Abstract Background Tuberculosis, characterized by the World Health Organization as a global health emergency, is a disease of global impact. Objective To investigate a series of tuberculosis cases during 17 years in Ouro Preto, Minas Gerais, Brazil, considering the historic relationship between mining and the disease. Method Data was obtained through the city's system of tuberculosis notifications, plus active search through medical records, and compared to the amount of notified cases present in the System of Information of Notifications Complications. For trend analysis, polynomial regression models were used for the historic series. Results The average age was 40.3 ± 16.4 years old. Men showed 2.23 times more cases and chances (odds ratio) of 2.07 times higher for negative outcomes. The most observed form was lung (85%) and HIV serology was performed in only 16.3% of the logs. The main observed outcome was a cure (70%) and negative outcomes accounted for 20.2% of the logs. The average incidence rate was 29.76 and 16.23 cases/100 thousand inhabitants in the city and district zones, respectively. Conclusion Despite the historical relationship between mining and tuberculosis in the municipality, it is observed that the same still presents worrying vulnerabilities about disease surveillance, temporal series analysis suggested a decline in the proportion of cases cured between 2009 and 2015.

Resumo Este estudo avaliou o uso de monogenóideos parasitos das brânquias de Sciades herzbergii (Siluriformes/Ariidae) como bioindicadores de qualidade ambiental em ecossistemas estuarinos amazônicos. Os peixes foram capturados nos canais das marés em uma área impactada - IA, próxima ao porto de São Luís, e uma área de referência - RA, no estuário do Caeté, Bragança. A influência do local de captura e sazonalidade na abundância do parasita, variáveis ambientais e dados biométricos dos hospedeiros foram verificados. Um total de 416 espécimes de S. herzbergii foram analisados. O peso e o comprimento total dos peixes da RA foram maiores do que os dos IA. O fator de condição relativo foi influenciado pela sazonalidade. Um total de 4.265 espécimes de monogenóideos das seguintes espécies foram identificados: Chauhanellus boegeri, C. susamlimae, C. velum, Calceostomella herzbergii e Dactylogyridae gen. sp. A abundância parasitária média sazonal de C. susamlimae foi significativamente diferente, com os maiores valores registrados durante a estação seca. A abundância média de C. herzbergii foi influenciada pela sazonalidade e pelo local de captura. Durante o período chuvoso, os índices parasitários na RA foram superiores aos da IA. C. herzbergii é um bioindicador sensível à baixa qualidade da água, principalmente em relação à turbidez da água em estuários amazônicos.

Abstract This study evaluated the use of gill parasitic monogenoideans from Sciades herzbergii (Siluriformes: Ariidae) as bioindicators of environmental quality in Amazonian estuarine ecosystems. Fish were caught in the tidal channels in an impacted area - IA, near the port of São Luís and a reference area - RA, in the Caeté estuary, Bragança. The influence of the capture site and seasonality on parasite abundance, environmental variables and biometric data of hosts were verified. A total of 416 S. herzbergii specimens were analyzed. The weight and total length of fish from the RA were greater than those of the IA. The relative condition factor was influenced by seasonality. A total of 4,265 monogenoidean specimens from the following species were identified: Chauhanellus boegeri, C. susamlimae, C. velum, Calceostomella herzbergii and Dactylogyridae gen. sp. The seasonal mean parasitic abundance of C. susamlimae was significantly different, with the highest values recorded during the dry season. The mean abundance of C. herzbergii was influenced by seasonality and by the capture site. During the rainy period, the parasite indices in the RA were higher than those of IA. C. herzbergii is a bioindicator sensitive to low water quality, especially in relation to water turbidity in Amazon estuaries.

Resumo Objetivou-se com esta pesquisa avaliar o efeito da Aflatoxina B1 (AFB1) na digestibilidade dos nutrientes e no perfil hematológico de equinos. O ensaio durou 40 dias, sendo 12 dias para adaptação e 28 dias para experimentação. No período experimental, os cavalos foram distribuídos em delineamento inteiramente casualizado, com três tratamentos, com quatro animais cada. Os tratamentos utilizados foram 0 µg/kg (controle), 50 µg/kg e 100 µg/kg de AFB1 adicionados ao concentrado da dieta basal. A dieta basal continha alimentos naturalmente contaminados com micotoxinas. Um ensaio de digestibilidade foi realizado no final do período experimental, pelo método de coleta parcial de fezes utilizando o LIPE® como indicador. Amostras de sangue foram coletadas uma vez por semana, durante o ensaio para avaliações hematológicas e bioquímicas. Os resultados dos parâmetros hematológicos, bioquímicos e do ensaio de digestibilidade foram submetidos à análise de variância (ANOVA) e comparados pelo teste de Tukey a 5% de significância. As aflatoxinas da dieta aumentaram a contagem de leucócitos, principalmente os neutrófilos maduros. A creatina quinase e a fosfatase alcalina (P<0,05) apresentaram maior atividade nos equinos alimentados com dietas com maior toxicidade. A digestibilidade dos nutrientes não foi alterada pelos níveis de micotoxinas presentes nas dietas (P>0,05).

Abstract This study aimed to evaluate the effect of aflatoxin B1 (AFB1) on the digestibility of nutrients and the hematological profile of horses. The assay lasted 40 days, with 12 days for adaptation and 28 days for experimentation. In the experimental stage, the horses were distributed in a completely randomized design, including three treatment groups with four animals in each group. The treatments used included 0 µg/kg (control), 50 µg/kg, and 100 µg/kg of AFB1 added to a concentrate in the basal diet. The basal diet contained mycotoxins from naturally contaminated feed. A digestibility essay was carried out at the end of the experimental period through partial feces collection, with LIPE® as an indicator. Blood samples were collected once a week during the assay for hematological and biochemical evaluations. The results of the hematological and biochemical parameters were submitted to analysis of variance (ANOVA) and compared by the Tukey test at 5% significance. The aflatoxins in the diet increased the leukocyte count, especially that of mature neutrophils. Creatine kinase and alkaline phosphatase (P < 0.05) activities were higher in horses fed more toxic diets. The digestibility of nutrients was unaffected by the level of mycotoxins in the diet (P > 0.05).

Abstract Introduction: Coronary artery bypass grafting (CABG) is the most frequently performed heart surgery in Brazil. Recent international guidelines recommend that national societies establish a database on the practice and results of CABG. In anticipation of the recommendation, the BYPASS Registry was introduced in 2015. Objective: To analyze the profile, risk factors and outcomes of patients undergoing CABG in Brazil, as well as to examine the predominant surgical strategy, based on the data included in the BYPASS Registry. Methods: A cross-sectional study of 2292 patients undergoing CABG surgery and cataloged in the BYPASS Registry up to November 2018. Demographic data, clinical presentation, operative variables, and postoperative hospital outcomes were analyzed. Results: Patients referred to CABG in Brazil are predominantly male (71%), with prior myocardial infarction in 41.1% of cases, diabetes in 42.5%, and ejection fraction lower than 40% in 9.7%. The Heart Team indicated surgery in 32.9% of the cases. Most of the patients underwent cardiopulmonary bypass (87%), and cardioplegia was the strategy of myocardial protection chosen in 95.2% of the cases. The left internal thoracic artery was used as a graft in 91% of the cases; the right internal thoracic artery, in 5.6%; and the radial artery in 1.1%. The saphenous vein graft was used in 84.1% of the patients, being the only graft employed in 7.7% of the patients. The median number of coronary vessels treated was 3. Operative mortality was 2.8%, and the incidence of cerebrovascular accident was 1.2%. Conclusion: CABG data in Brazil provided by the BYPASS Registry analysis are representative of our national reality and practice. This database constitutes an important reference for indications and comparisons of therapeutic procedures, as well as to propose subsequent models to improve patient safety and the quality of surgical practice in the country.

RESUMO Objetivo determinar a confiabilidade do equipamento S-FLEX® para verificar pressão de sucção não nutritiva em recém-nascidos a termo. Métodos estudo transversal e quantitativo, com 30 recém-nascidos a termo, saudáveis, entre o primeiro e terceiro dia de vida, internados em um hospital terciário. Foram realizadas duas avaliações em cada recém-nascido, por dois examinadores distintos, com intervalo de quatro horas. Foram realizadas três determinações sucessivas da pressão máxima e a média de sucção não nutritiva, por meio do equipamento S-FLEX®. Para determinar a confiabilidade, avaliou-se a repetibilidade e a reprodutibilidade das medidas. Análise de variância e coeficiente de correlação intraclasse foram utilizados para análise dos resultados. Resultados a pressão máxima de sucção, na 1ª avaliação, foi de 10,44 (± 2,25), 10,12 (± 2,25) e 9,73 (± 2,61) mmHg, (p = 0,120), respectivamente para a 1ª, 2ª e 3ª medidas. Na 2ª avaliação, foi de 10,10 (± 2,35), 9,98 (± 2,02) e 10,37 (± 2,29), (p = 0,404). A pressão média de sucção na 1ª avaliação foi de 3,64 (± 1,04), 3,59 (± 1,04) e 3,56 (± 1,03), (p = 0,852) e, na 2ª avaliação, foi 3,59 (± 1,04), 3,51 (± 0,92) e 3,63 (± 1,04), (p = 0,721). Para a pressão máxima de sucção, o coeficiente de correlação foi de 0,708 (p = 0,001); para a pressão média foi de 0,828 (p<0,001), evidenciando boa e excelente correlação, respectivamente. Conclusão o S-FLEX® mostrou-se um equipamento confiável para determinar a pressão de sucção não nutritiva em recém-nascidos a termo, saudáveis.

ABSTRACT Purpose to establish the reliability of the S-FLEX® to measure non-nutritive sucking pressure in full-term newborns. Methods a cross-sectional and quantitative study was conducted in a tertiary hospital, on 30 one- to three-days-old infants born healthy and at term. Each newborn was evaluated twice, each time by a different examiner, at an interval of 4 hours. In each assessment, maximum and mean non-nutritive sucking pressure were measured three times consecutively. The reliability of the instrument was investigated by calculating the repeatability and reproducibility of these measurements. Repeatability was determined by analyzing the consecutive measures taken by each examiner using repeated-measures analysis of variance (ANOVA). Results the maximum sucking pressure was found to be 10.44 (± 2.25), 10.12 (± 2.25) and 9.73 (± 2.61) mmHg, (p = 0.120), in the first, second and third consecutive measurements, respectively. In the second evaluation, the values were 10.10 (± 2.35), 9.98 (± 2.02) and 10.37 (± 2.29) mmHg, (p = 0.404). The measurements of mean sucking pressure taken by examiner A in the first evaluation were 3.64 (± 1.04), 3.59 (± 1.04) and 3.56 (± 1.03) mmHg, (p = 0.852), respectively, and, in the second evaluation, 3.59 (± 1.04), 3.51 (± 0.92) and 3.63 (± 1.04) mmHg, (p = 0.721). The correlation coefficients between measurements of maximum and mean sucking pressure were 0.708 (p = 0.001) and 0.828 (p<0.001), which are indicative of good and excellent correlations, respectively. Conclusion The S-FLEX® can provide reliable measurements of maximum and mean non-nutritive sucking pressure in healthy full-term newborns.

ABSTRACT This study evaluated the influence of coastcross hay substrate hydration and equine fecal inoculum dilution on the parameters of fermentation and microbiology in in vitro essays. A 2 × 2 factorial block design was used. The first factor was hydration of the coastcross hay substrate 12 h before incubation or at the time of incubation, and the second factor was the dilution of fecal inoculum with a nutrient solution in a weight: weight ratio of 1:1 or 1:3. Degradation of the dry matter (DM), organic matter (OM), and neutral detergent fiber (NDF) were evaluated at 24, 48, and 72 h. Microorganisms were counted 24 h after inoculation. The ammoniacal nitrogen concentration (NH3-N), pH, and cumulative gas production were measured up to 72 h and adjusted by the non-linear Gompertz regression model. Hydration of substrate and time of incubation increased nutrient degradation of coastcross hay, as well as the final volume of gases and the concentration of Streptococcus spp. The 1:3 dilution increased the final pH and Streptococcus spp. concentration. The hydration of substrate did not have any effect on NH3-N, Lactobacillus spp., cellulolytic, and total anaerobic bacteria concentrations. In addition, no effect of hydration was observed on the fermentation rate and the maximum fermentation time on the model used. The fermentation profile of the grass substrate is not affected by dilution, and, therefore, horse feces can be used as a source of inoculum in in vitro fermentation trials. Hydration increases the gas volumes and the nutrient degradation of grass hay, renders the lag phase time insignificant and, therefore, can be irrelevant in terms of fermentation model settings.

ABSTRACT The objective of this study was to evaluate the effect of prebiotic fructooligosaccharide (FOS) supplementation on the development of Mangalarga Marchador suckling foals. Sixteen Mangalarga Marchador foals, from birth to 75 days of age, were evaluated in a completely randomized design, with two treatments (experimental group and control group) with eight repetitions (animals). The foals were evaluated through body weight, morphometric, and circumferential measures. The daily, weekly, and cumulative weight gains were recorded and the morphometric measures were: withers height, croup height, body length, mid-back height, mid-back width, and thorax, shin, knee, and forearm circumferences. The mean body weight was 32.3 and 77.9 kg at birth and 75 days of age, respectively. The mean withers height was 86 and 103.8 cm at birth and 75 days of age, respectively, and the mean body length was 63.9 cm at birth, reaching 89.1 cm at 75 days of age. No significant differences in the FOS supplementation or interaction of age versus supplementation between the experimental and control groups were observed for any of the parameters evaluated. However, there were significant differences between the ages. Supplementation with prebiotic FOS does not affect the development of the Mangalarga Marchador suckling foals from birth to 75 days of age.

Abstract Objective: To report the early results of the BYPASS project - the Brazilian registrY of adult Patient undergoing cArdiovaScular Surgery - a national, observational, prospective, and longitudinal follow-up registry, aiming to chart a profile of patients undergoing cardiovascular surgery in Brazil, assessing the data harvested from the initial 1,722 patients. Methods: Data collection involved institutions throughout the whole country, comprising 17 centers in 4 regions: Southeast (8), Northeast (5), South (3), and Center-West (1). The study population consists of patients over 18 years of age, and the types of operations recorded were: coronary artery bypass graft (CABG), mitral valve, aortic valve (either conventional or transcatheter), surgical correction of atrial fibrillation, cardiac transplantation, mechanical circulatory support and congenital heart diseases in adults. Results: 83.1% of patients came from the public health system (SUS), 9.6% from the supplemental (private insurance) healthcare systems; and 7.3% from private (out-of -pocket) clinic. Male patients comprised 66%, 30% were diabetics, 46% had dyslipidemia, 28% previously sustained a myocardial infarction, and 9.4% underwent prior cardiovascular surgery. Patients underwent coronary artery bypass surgery were 54.1% and 31.5% to valve surgery, either isolated or combined. The overall postoperative mortality up to the 7th postoperative day was 4%; for CABG was 2.6%, and for valve operations, 4.4%. Conclusion: This first report outlines the consecution of the Brazilian surgical cardiac database, intended to serve primarily as a tool for providing information for clinical improvement and patient safety and constitute a basis for production of research protocols.

ABSTRACT The objective of this study was to examine serum retinol and some mineral (zinc, iron, calcium, phosphorus, magnesium, and copper) levels in seven Mangalarga Marchador colts aged 329.48 days, reared on pasture in the city of Montes Claros, MG, Brazil, during the dry season. Equines were evaluated for four periods of 45 days during the total study period of five months. The foals had access to Panicum maximum cv. Tanzania pasture, while water and mineral salt lick were provided ad libitum. Blood samples were taken to determine serum retinol and levels of minerals, along with pasture samples to quantify beta-carotene in the grass. The results indicated that retinol levels varied (2.87 to 1.97 µg/dL) and remained below the standard levels. The levels of zinc, iron, calcium, and phosphorus did not vary significantly with average values of 36.79 µg/dL, 77.32 µg/dL, 10.33 mg/dL, and 9.99 mg/dL, respectively. However, zinc and calcium remained below standard concentrations of 60-120 µg/dL and 10.8-13.5 mg/dL, respectively, since the beginning of the study. On the other hand, copper and magnesium levels decreased over time (97.76 to 77.56 mg/dL and 2.86 to 2.21 µg/dL, respectively), but showed normal levels for horses during the research. Beta-carotene in grass showed a downward trend over time from 38.53 to 0.09 mg/kg of dry matter. The results also indicated a significant relationship between serum retinol and serum copper levels. Vitamin A supplementation is necessary whenever foals are fed pastures during the dry season.

ResumoO objetivo com este estudo foi observar as similaridades e asimetrias existentes na criação de cavalos no sul do Brasil e Argentina, a partir de análise dos aspectos produtivos, comerciais e da saúde dos equinos. A metodologia utilizada compreendeu levantamento de dados, através de aplicação de questionário a campo (fontes primárias) e pesquisas bibliográficas (fontes secundárias). A amostragem abrangeu criadores de equinos do Rio Grande do Sul e Argentina. O questionário foi elaborado baseado no Estudo do Complexo do Agronegócio Cavalo no Brasil, dividido em: Aspectos de Proodução, Sanitários e Comerciais. Foi realizada análise descritiva dos dados e as frequências relativas foram comparadas pelo teste Qui-quadrado (P<0,05). Observou-se similaridades nos aspectos relacionados à criação e comercialização, mas assimetria relacionada à saúde dos equinos. No sul do Brasil 29,0% dos proprietários vivem da criação de cavalos, enquanto 67,7% exercem outras atividades remuneradas. Observou-se similaridade no controle de endoparasitas e assimetria em relação à ectoparasitas. A alta percentagem de controle de doenças observada na Argentina pode estar relacionada à tecnificação e a mão de obra treinada. Contudo, observou-se similaridade entre as fazendas do sul do Brasil e Argentina em relação ao controle sanitário dos rebanhos de equinos. A respeito das diversas assimetrias e semelhanças observadas, destaca-se a importância do agronegócio cavalo na produção de emprego e renda, bem como a contribuição econômica e cultural para ambos os países. Além disso, há necessidade de políticas públicas para a promoção da indústria do cavalo.

AbstractThis study was carried out in order to verify the asymmetries and similarities in horse breeding in the Brazilian South region and Argentina, analyzing the productive, health and trade aspects. Data collection were performed with questionnaires in fieldwork (primary sources) and bibliographic searches and surveys (secondary sources). The sample consisted of horses breeders in Brazil, Rio Grande do Sul State, and in Argentina. The questionnaire was based on the Brazilian Study of Horse Agribusiness Complex, divided into: Production Aspects, Health Issues and trade aspects. Descriptive data analysis and relative frequencies were compared using the chi-square (χ2) test at 5% probability. It was observed that there was a similarity in several aspects related to the breeding and trade horse agribusiness, whereas in the health aspects there was asymmetry in certain aspects. In the Southern Brazil, 29.0% of the owners live in the breeding farm and 67.7% have another remunerated activity. There was a similarity in the endoparasites system control and an asymmetry in the ectoparasites control. There was a higher percentage of diseases control in Argentina, which may be related to technification and qualification of workforce. However, regarding the equine sanitary control, there was a similarity between the farms of Southern Brazil and Argentina. Despite of all asymmetries and similarities, there is a relevance of horse agribusiness on generating jobs and income source, as well as the cultural and economic contribution in both countries. Furthermore, there is a necessity of public policies from government authority to promote the horse industry.

Este trabalho teve como objetivos avaliar a cinética de passagem da digesta, as características físico-químicas e o tamanho da partícula da digesta do cólon ventral direito (CVD) de equinos alimentados com feno de coastcross com diferentes tamanhos de partículas. Utilizaram-se quatro equinos fistulados CVD alimentados exclusivamente com feno de coastcross: inteiro; feno picado, moído (5 mm) e moído (3 mm). Utilizou-se o delineamento em quadrado latino 4x4. Cada período experimental teve 10 dias de adaptação às dietas, quatro dias de coleta de fezes e um dia de coleta do conteúdo do cólon. A cinética de passagem da fase sólida e líquida da digesta no trato digestório foi estimada através do tempo médio de retenção (TMR), da taxa de passagem (k) e do tempo de trânsito (TT) utilizando os indicadores: Cr-FDN e Co-EDTA. O TT da fase sólida da digesta foi maior em 3 horas (P<0,05) nos equinos alimentados com o feno moído, em relação às outras formas do feno. Não houve diferença (P>0,05) no TMR e k tanto da fase líquida quanto na sólida da digesta em função das diferentes formas físicas do feno. No entanto, houve maior velocidade de passagem da fase líquida de 3,28 h-1, comparada à fase sólida, de 2,73 h-1, em todas as dietas. Quando se forneceu feno moído a 3 mm foram observados o menor tamanho de partícula e o menor teor da fibra em detergente neutro na digesta do cólon, com valores de 0,51 mm e 53,5%, respectivamente. A moagem do feno aumentou o tempo de trânsito da fase líquida no trato digestório dos equinos, sem interferir na cinética da fase sólida da digesta. A moagem do feno reduziu os teores de FDN e o tamanho médio das partículas no CVD.

This study was conducted to evaluate the kinetics, physicochemical characteristics and particle size of digesta in the right ventral colon (RVC) of horses fed coastcross hay ground to different degrees. Four horses fitted with cannulae in the RVC were used and were fed the following forms of hay: long, chopped, ground to 5 mm and ground to 3 mm. A Latin Square 4x4 study design was used. Each experimental period included 10 days for diet adaptation, four days for feces collection and one day for digesta collection. The kinetics of the particulate and solute phases of digesta were evaluated based on the mean retention time (MRT), passage rate (k) and transit time (TT) using two external markers: Cr-NDF and Co-EDTA. The TT of solid phase digesta was 3 hours longer (P<0.05) for ground hay than with the other physical forms of hay. There was no difference (P>0.05) in k or MRT in either the liquid or solid phase of digesta as a function of the different degrees of hay grinding. However, the liquid phase of digesta presented a higher k than the solid phase, with values of 3.28 and 2.73 h-1 being obtained, respectively. The smallest particle size and the lowest neutral detergent fiber contents in colon digesta were observed when hay ground to 3 mm was offered, leading to values of 0.51 mm and 53.46%, respectively. Grinding the hay increased the transit time of the liquid phase in the digestive tract of the horses, whereas no change in the kinetics of the solid phase digesta was observed. The grinding of hay reduced the NDF and the average particle size in the right ventral colon.

A comparação da produção e composição do leite, do escore corporal e dos custos com a suplementação mineral comercial e seletiva foi feita utilizando-se dois grupos de 16 cabras lactantes por 164 dias. Não houve diferenças significativas na produção de leite dos animais que ingeriram os dois tipos de suplementos minerais. Não houve efeito do tipo de suplementação mineral em relação a composição do leite em gordura, proteína e lactose bem como na contagem de células somáticas (CCS). O consumo médio diário do suplemento comercial foi 1,76 vezes maior do que o suplemento contendo apenas cloreto de sódio associado ao sulfato de cobre. A utilização da mistura mineral seletiva, formulada com base no exame clínico-nutricional dos animais, gerou uma redução de aproximadamente 7 vezes o custo com a suplementação mineral do rebanho caprino.

Comparison of milk production and composition, body condition score and the cost of commercial or selective mineral supplementation was made using two groups of 16 lactating goats during 164 days. No significant difference in milk production between treatments was found. There was no effect of the type of mineral supplement on the composition of milk fat, protein and lactose as well as on the somatic cell count (SCC). The average of daily intake of the commercial supplement was 1.76 times greater than the supplement containing only sodium chloride associated with copper sulfate. The use of the selective mineral mixture based on clinical-nutritional examination of the animals led to a reduction of about 7 times the amount spent by mineral supplementation of this goat herd.

O trabalho avaliou o efeito da suplementação com leveduras na dieta de equinos em treinamento, sobre a digestibilidade dos nutrientes e o desempenho metabólico dos animais. Doze equinos foram distribuídos em 2 grupos: Pr (equinos que receberam 20 g de probióticos diariamente) e Controle. A dieta foi composta de volumoso (haylage) e concentrado comercial e todos os equinos foram treinados durante 6 semanas. A digestibilidade dos nutrientes foi avaliada utilizando o indicador LIPE® (7 dias) e a coleta de fezes foi realizada durante cinco dias. Foi analisado MS, PB, DE, P, FDN, FDA, HCEL e lignina. Antes e após o treinamento, todos os cavalos foram submetidos a um teste incremental ergoespirométrico. Os equinos que receberam leveduras vivas apresentaram um aumento (p <0,05) de 4,1% na digestibilidade da HCEL. Após o treinamento, ambos os grupos apresentaram maior tolerância à fadiga, com um aumento na AT e no VO2max. O treinamento melhorou o desempenho dos animais, e a digestibilidade da hemicelulose e DE foi maior no grupo Pr, mas esses aumentos não melhoraram o desempenho desses animais.

This research analyses the yeast supplementation effect on the digestibility of nutrients and metabolic performance in training horses. Twelve horses were assigned into 2 groups: Pr (20 g of probiotics daily per horse) and control. The diet consisted of roughage (haylage) and commercial rations and all horses were trained for 6 weeks. LIPE® indicator was used during 7 days and feces collected for five days to determine nutrient digestibility. DM, CP, DE, P, NDF, ADF, HCEL and lignin were determined. All horses were subjected to incremental ergospirometry test before and at the end of training. Horses that received live yeast showed an increase (p<0.05) of 4.1% in the digestibility of HCEL. After training, both horse groups presented higher tolerance to fatigue, with an increase in AT and VO2max. The training improved animal performance, hemicellulose digestibility and DE was higher in Pr, but these increases did not improve the performance of these animals.
