Abstract The employees of integrated poultry farms are essential components in the development of the human and social capital of organizations. The general aim of the study was to identify the people management policies adopted on the properties of integrated poultry farmers who use the Dark House system, linked to the Poultry Farmers' Association in the Dourados-MS region. Specifically, the aim was to analyse the degree of organizational communication between employees and integrated poultry farmers; to analyse the working conditions of employees in the poultry houses; and to identify the factors that influence the integrated poultry farmer's intention to adopt a people management policy in the poultry houses. The research is characterized as qualitative-quantitative, based on the theory of planned behavior (TCP) and the theory of organizational climate. The results of the TCP indicate that poultry farmers recognize the importance of people management policies, taking into account the opinions of the integrating company and government agencies, but report a lack of support and training for their implementation. The organizational climate survey revealed that integrated poultry farms lack robust people management policies, highlighting the need for improvements in communication and working conditions. organizations system Farmers DouradosMS Dourados MS region Specifically houses farmer s qualitativequantitative, qualitativequantitative qualitative quantitative, quantitative qualitative-quantitative (TCP agencies implementation

ABSTRACT This study aimed to analyze the economic viability of the implementation of a mechanized harvesting of broilers where the activity is carried out entirely manually. The viability indicators used were net present value (NPV), net future value (NFV), net uniform value (NUV), discounted payback (DP), and internal rate of return (IRR). Scenario analysis, sensitivity, and Monte Carlo simulation were performed in the present study. The results showed that the initial investment was US$ 1,868,302.76. The average price paid by the slaughterhouse to third-party manual harvesting companies was US$ 18.17 per thousand broilers, which was converted into revenue in the cash flow of the project. The cash flow result was positive at US$ 22,256.14 over the entire study period considering a daily catch of 144 thousand broilers. The results of the economic viability analysis were NPV of US$ 64,786.23, NFV of US$ 333,382.11, NUV of US$ 735.19, DP of 13.82 years, IRR of 0.965 monthly, and modified IRR of 0.933 monthly. These values prove the economic viability of implementing the project considering the market conditions at the time of the study. The analysis of scenarios showed great sensitivity to the exchange rate and the price of fuels. The Monte Carlo simulation highlighted a moderate risk of negative NPV, emphasizing the importance of considering this variable when making decisions. Despite these challenges, the potential benefits of mechanized harvesting, such as increased efficiency and reduced labor costs, make it a promising alternative to manual harvesting, even for small to medium-sized poultry industries. manually , (NPV) NFV, (NFV) NUV, (NUV) DP, (DP) IRR. .

ABSTRACT We investigated the influence of poultry rearing factors, including strain, type of ventilation, and sex on the slaughter characteristics of broiler chickens. Factorial analysis of mixed data was employed to analyze the data from broiler flocks slaughtered between 2018 and 2020 in Mato Grosso do Sul, comprising 2,684 flocks and 82,486,500 birds. The characterization information considered included age at slaughter, average weight, date of slaughter, percentage of pododermatitis, percentage of scratches, percentage of pre-slaughter condemnations, percentage of slaughter condemnations, percentage of total condemnation, percentage of field mortality, type of ventilation, strain, and sex. The factorial analysis of mixed data aimed to identify the relationships between pre-slaughter factors and slaughter characteristics. Five main components, explaining 85.5% of the total data variance, were derived from the analysis. Age, generated value per kilo of product, and percentage of pre-slaughter condemnations exhibited positive correlations. Negative pressure ventilation was found to be more closely associated with the percentage of pododermatitis, while the dark house system showed a stronger association with the percentage of total condemnation and percentage of pre-slaughter condemnation. The Cobb strain and female sex were found to be more strongly related to the generated value of the product. Strain, sex, and type of ventilation were identified as decisive factors influencing the characteristics of meat yields and the economic results of poultry activity in slaughterhouses. Moreover, it was observed that percentages of scratches and pododermatitis were negatively correlated with the value generated ($/kg) by broiler flocks, and they were more closely associated with positive pressure ventilation systems, Ross strain, mixtures of strains within the same flock, and male chickens. It was possible to prove the strong interdependence between the rearing stage of broiler chickens and the slaughterhouse, which needs to be considered in decision making by agroindustry to achieve an ideal rearing model. 201 202 Sul 2684 2 684 2,68 82486500 82 486 500 82,486,50 birds weight preslaughter pre mortality components 855 85 5 85.5 variance Age product correlations Strain slaughterhouses Moreover $/kg kg ($/kg systems flock slaughterhouse model 20 268 68 2,6 8248650 8 48 50 82,486,5 85. 26 6 2, 824865 4 82,486, 82486 82,486 8248 82,48 824 82,4 82,

Resumo: O objetivo deste artigo foi identificar o papel da liberalização do comércio de alimentos na segurança alimentar tomando como base dados científicos da literatura internacional e visando elucidar pontos positivos ou negativos. Uma revisão sistemática foi realizada nas bases Web of Science e Scopus no período de 2015 a 2019. Foram identificados dezesseis trabalhos, observando os critérios de inclusão e exclusão estabelecidos. Foi possível constatar que a literatura sobre o tema em questão permanece ambígua, não havendo consenso sobre os reais ganhos ou perdas. A natureza e a magnitude do efeito da liberalização na segurança alimentar dependem de vários fatores, como o grau de adaptabilidade dos pobres às mudanças nas condições econômicas; o grau de exposição dos países às importações de alimentos; a presença de condições iniciais favoráveis; as medidas de acompanhamento; e o horizonte temporal considerado na pesquisa.

Abstract: This paper aimed to identify in the international literature on food security the scientific results about the role of trade liberalization in the same. A systematic review was used in the Web of Science and Scopus databases from 2015 to 2019. It was identify 16 studies according the inclusion and exclusion criteria. It was found that the literature on the issues in question remains ambiguous, with no consensus on the real gains or losses. The nature and magnitude of the effect of liberalization on food security depends on several factors, such as: the degree of adaptability of the poor to changes in economic conditions; the degree of exposure of countries to food imports; the presence of favorable initial conditions; accompanying measures; and the time horizon considered in the research.

ABSTRACT. Wooden breast myopathy (WB) strongly affects the poultry industry mainly in terms of consumers rejection and economical loses, due to morphological changes in broiler muscle tissue and consequently low meat quality. The aim of this study is to evaluate the histomorphometry of muscle fibers of breast fillets of broilers with severity levels of WB myopathy. The histological evaluation considered 30 samples of the pectoralis major muscle and the level of WB myopathy (ten normal fillets, ten moderate fillets, and ten severe fillets). Fillets with a severe level of WB present low average fiber number, high average fiber diameter, low percentage of fibers with diameter of less than 20 µm, low percentage of fibers with diameter between 20 and 40 µm, and high percentage of fibers with diameter between 40 and 70 µm. Fiber cross-sectional area is greater in fillets affected by moderate and severe WB. Thus, fillets with a severe level of WB damage the muscle fiber structure and contribute more severely to the degenerative processes of breast meat.

ABSTRACT The objective of this study was to determine the energy values and metabolizability of different lipid sources in the diet of Japanese quail at the laying phase. The quail were distributed in a completely randomized design with ten replications of seven poultry per treatment, totaling six treatments: basal feed (control) and basal feed containing 10% soybean oil, corn oil, canola oil, sunflower oil, and poultry fat. The values of nitrogen-corrected apparent metabolizable energy (AMEn) and the metabolizability coefficient (MC%) were evaluated. No significant difference was found between the different lipid sources for AMEn (kcal/kg) and MC (%). The value of metabolizable energy corrected for nitrogen for soybean oil was 8,790 kcal/kg; 8,773 kcal/kg for corn oil; 8,784 kcal/kg for canola oil; 8,788 kcal/kg for sunflower oil; and 8,681 kcal/kg for poultry fat in laying Japanese quail. The digestibility coefficients were 93.88% for soybean oil, 93.53% for corn oil, 93.32% for canola oil, 93.74% for sunflower oil, and 93.06% for poultry fat. phase treatment treatments control (control 10 nitrogencorrected (AMEn MC% (MC% evaluated kcalkg kcal kg (kcal/kg %. % .

Abstract This study aims to evaluate the residual effect of different lipid sources in the diet of Japanese quails (Coturnix japonica) in the rearing phase on the performance and egg quality in the initial phase of egg-laying. In the first stage, 400 Japanese quails aged 21 days were used, being distributed in a completely randomized experimental design, with five treatments and ten replicates of eight birds/replicate Treatments consisted of basal ration (BR) with 2.5% soybean oil; BR with 2.5% corn oil; BR with 2.5% cottonseed oil; BR with 2.5% sunflower oil; and BR with 2.5% canola oil. At 42 days, maintaining the initial design, all quails received a basal ration with soybean oil, in order to evaluate the residual effect of the previous phase on the performance and egg quality in the initial phase of egg-laying (43 - 84 days). The different lipid sources did not affect the performance of quails in the initial phase of production. For egg quality, yolk height, yolk diameter, yolk index, gravity, and Haugh unit (HU) showed better results in the treatment using sunflower oil. There was a residual effect of the use of lipid sources of vegetable origin in the rearing phase diet of Japanese quails on egg quality traits. Lipid sources from soybean, corn, cottonseed, canola, and sunflower seeds can be used as energy sources in the rearing diet of egg-laying quails for not being harmful to their initial performance. The longevity in egg production of quails fed with different lipid sources in the rearing phase was similar.

Resumo A pesquisa foi conduzida com objetivo de avaliar o efeito residual de diferentes fontes lipídicas na dieta de codornas japonesas (Coturnix japonica) na fase de recria sob o desempenho e a qualidade de ovos na fase inicial de postura. Na primeira etapa foram utilizadas 400 codornas japonesas com idade de 21 dias, as aves foram distribuídas em tratamentos seguindo um delineamento inteiramente casualizado com dez repetições, de oito aves, em cinco tratamentos: ração basal (RB) com 2,5% de óleo de soja, RB com 2,5 % de óleo de milho, RB com 2,5% de óleo algodão, RB com 2,5% de óleo de girassol e RB com 2,5% de óleo de canola. Aos 42 dias mantendo o delineamento inicial, todas aves receberam ração basal com óleo de soja, para que fosse avaliado o efeito residual da fase anterior sobre o desempenho e a qualidade dos ovos na fase inicial de postura (43 - 84 dias). As diferentes fontes lipídicas não afetaram o desempenho das aves na fase inicial de produção. Para a qualidade dos ovos, os parâmetros de altura, diâmetro e índice de gema, gravidade e UH foram melhores no tratamento com utilização de óleo de girassol. Houve efeito residual da utilização de fontes lipídicas de origem vegetal na dieta em fase de recria de codornas japonesas sobre as características da qualidade dos ovos. As fontes lipídicas oriundas das sementes de soja, milho, algodão, canola e girassol podem ser utilizadas como ingredientes energéticos na dieta de recria de codornas poedeiras por nâo serem prejudiciais ao desempenho inicial das aves. A longevidade na produção dos ovos das aves alimentadas com diferentes fontes lipídicas na fase de recria foi semelhante.

ABSTRACT. The objective is to evaluate the effects of the inclusion of yerba mate in the diet on the yield and quality of chicken meat stored frozen for 120 days after slaughter. The birds were distributed in a completely randomized design, with four treatments, and eight replications with 25 birds each. The treatments consisted of providing a basal diet with 1, 2, 4, and 6 g kg-1 of ground dehydrated Yerba mate. At slaughter, temperature, pH, and carcass yield were measured. 120 days after meat freezing, measurements of pH, colorimetry, cooking weight loss (CWL), shear force, and water retention capacity were estimated. The parameters evaluated after slaughter showed regression effects on breast and drumstick temperature. Breast temperature showed a decreasing linear effect (R2=0.61). For the variable thigh temperature, there was a negative quadratic effect (R2=0.66). The quality characteristics of breast and drumstick evaluated 120 days after freezing showed an increasing linear effect of drumstick CWL (R2=0.38). Yerba mate can be included in up to 6 g kg-1 in chicken feed without changing pH, color, and meat tenderness after 120 days of freezing, maintaining carcass and cut yields.

Abstract Minced fish (MF) is an interesting material for development of novel fish products; however, the mechanical deboning process interferes with MF quality, by increasing the lipid oxidation. This study reports the effect of Ceylon cinnamon (Cinnamomum zeylanicum) hydro-ethanolic bark extracts as natural antioxidants on both washed and unwashed MF of broadband anchovy during six months of storage at -18 °C. Spray-dried cinnamon extract (DC) and spray-dried cinnamon extract using maltodextrin 10DE (DCM) as a carrier were evaluated in relation to antioxidant activity in vitro. DC and sodium erythobarte were added to both washed and unwashed MF at 0.25% (w:w), whilst DCM was added at 1.055% (w:w). The DC extract presented higher antioxidant activity in vitro compared to DCM extract. The addition of cinnamon extracts reduced the lipid oxidation in washed and unwashed MF compared with the controls. C. zeylanicum extracts can be used to prevent lipid oxidation in MF during the frozen storage and are alternatives for food industries that seek to meet the demand of consumers increasingly concerned with the consumption of healthy foods.

RESUMO O objetivo deste estudo foi avaliar a influência da inclusão de níveis de farinha de alga calcária em substituição ao calcário calcítico na dieta sob a conservação de ovos em diferentes períodos de armazenamento. Foram utilizadas 140 codornas japonesas em um delineamento inteiramente casualizado composto por um fatorial 4x4. Sendo 4 inclusões de alga calcária (0%, 10%, 20% e 30%) e 4 períodos de armazenamento (0, 7, 14 e 21dias) com dez repetições de três ovos em cada. Foram avaliadas as variáveis de qualidade de ovos das aves. Os dados foram submetidos a análise de variância utilizando o teste de Tukey e regressão polinomial ao nível de 5% de significância. Não houve efeito da interação entre os fatores tempo de armazenamento e inclusão de alga calcárea (p>0,05). Houve efeito linear crescente no peso e espessura da casca em relação aos níveis de inclusão de alga calcárea. Houve efeito individual do tempo de armazenamento dos ovos (p>0,05) sobre parâmetros peso de ovo, coloração da gema, altura de albúmen e gema, peso e porcentagem da gema, albúmen, índice de gema, diâmetro de gema, gravidade especifica e unidade Haugh. A inclusão de até 30 % de alga calcária em substituição ao calcário calcítico na dieta codornas japonesas aprimora o peso e a espessura da casca do ovo, mas não influencia na conservação dos ovos até 21 dias de armazenamento.

ABSTRACT The aim of this study is to evaluate the influence of including levels of calcareous seaweed flour in replacement for calcite limestone on the diet under egg conservation at different storage periods. 140 Japanese quails were used in a completely randomized experiment consisting of a 4x4 factorial design. The factorial design was four inclusions of calcareous seaweed (0%, 10%, 20%, and 30%) and four storage periods (zero, seven, 14, and 21 days) with ten replications of three eggs each. The egg quality variables were evaluated. Data were subjected to analysis of variance using Tukey test and polynomial regression at a 5% significance level. There was no interaction effect between the factor's storage time and inclusion of calcareous seaweed (p>0.05). There was an increasing linear effect on shell weight and thickness in relation to inclusion levels of calcareous seaweed. There was an individual effect of egg storage time (p>0.05) on egg weight, yolk color, albumen and yolk height, yolk weight and percentage, albumen, yolk index, yolk diameter, specific gravity, and Haugh unit. The inclusion of up to 30% of calcareous seaweed in replacement for calcite limestone in the diet of Japanese quails improves the weight and thickness of eggshells but does not influence the conservation of the eggs up to 21 days of storage.

ABSTRACT. This study aimed to evaluate the influence of homeopathic products in diets of quails in the egg quality when submitted to different storage periods. In the trial we used 200 Japanese quails in a completely randomized design with 4 diets: reference diet, vehicle used in homeopathic products and 2 homeopathic products - Fertsigo® and Ovosigo® with ten replicates of three eggs in each. Egg quality parameters were evaluated during 3 storage periods. Data were evaluated as repeated measures in time, the effects of the interactions between treatments and time as well as their isolated effects were verified. There was the interaction between homeopathic products and storage time in the parameters of albumen and yolk height, Haugh unit, and yolk index, in which a reduction was obtained over time. For egg weight, yolk, albumen and shell, percentage of albumen, and percentage of eggshell there was a significant effect only for homeopathy. The inclusion of homeopathic additives increased egg weight. It is indicated the addition of the product with homeopathic basis Ovosigo® and FertSigo® in diets of Japanese quails in the laying phase resulting in better egg and components but did not influence the quality maintenance of eggs of Japanese quails in the periods evaluated.

RESUMO O presente estudo analisou a influência de dois protocolos de limpeza e desinfecção na frequência de Aspergillus spp. em instalações de frangos de corte. Realizou-se estudo observacional, aplicando-se dois protocolos de limpeza e desinfecção antes do alojamento de 960 pintainhos de um dia distribuídos aleatoriamente em 32 boxes com 30 aves. Foram realizados 2 experimentos independentes, que diferiam quanto ao material de cama, sendo nova no primeiro e reutilizada no segundo. Realizou-se dois tratamentos: Comum que incluiu varrição da matéria orgânica, umidificação do material residual com água sob baixa pressão, lavagem com detergente neutro e enxágue. O tratamento Europeu seguiu as recomendações do fabricante dos desinfetantes, incluindo remoção de matéria orgânica seca e úmida, umidificação, lavagem com água sob alta pressão, aplicação de detergente, enxágue e aplicação de dois desinfetantes compostos: glutaraldeído (250 g / L) + formaldeído (185 g / L); p-cloro-m-cresol (210 g / L). Foram coletadas amostras de superfícies e equipamentos antes e após a limpeza e desinfecção, aos 7, 14, 28 e 42 dias do período experimental para avaliação micológica, realizada em placas de Petri contendo AFPA (Aspergillus Flavus e Parasiticus Agar, Sigma Aldrich®). O tratamento Comum obteve maior presença de fungos nos pisos e paredes (83% vs. 0% p = 0,0030 e 50% vs. 0% p = 0,0450) no primeiro e segundo experimentos, respectivamente. Este estudo demonstra que a execução de um protocolo detalhado de limpeza e desinfecção, como o tratamento Europeu, reduz a presença de Aspergillus spp. em instalações de frangos de corte.

ABSTRACT The present study analyzes influence of two cleaning and disinfection protocols on frequency of Aspergillus spp. in broiler facilities. We conducted an observational study, applying two cleaning and disinfection protocols before housing 960 one-day-old broilers randomly allocated in 32 boxes with 30 birds. We considered two types of housing as independent experiments, which differed as to the bedding. First experiment consisted of new bedding materials, which we reused in second experiment. We applied two different treatments, Common treatment included sweeping organic matter, humidifying residual material with low pressure water, washing with water and neutral detergent, with posterior rinsing. European treatment was according to the standards of the manufacturer of disinfectants. Procedures included dry and humid organic matter removal, humidification, washing with high pressure water, application of detergent, rinsing, and application of two compound disinfectants: glutaraldehyde (250 g/L) + formaldehyde (185 g/L); p-chloro-m-cresol (210 g/L). To evaluate the presence of Aspergillus spp., we collected samples from surfaces and equipment before and after cleaning and disinfection, at 7, 14, 28, and 42 days of experimental period. Mycological assessment included streaking on Petri dishes containing AFPA (Aspergillus Flavus and Parasiticus Agar, Sigma Aldrich®). Common cleaning and disinfection treatment led to a higher presence of fungus in floors and walls (83% vs. 0% p = 0.0030 and 50% vs. 0% p = 0.0450) in first and second experiments, respectively. As this study demonstrates by using the European procedures, performing a detailed cleaning and disinfection protocol reduces the presence of Aspergillus spp. in broiler facilities.

RESUMO A erva mate ( Ilex paraguariensis) possui em compostos orgânicos com propriedades de modificar a composição química de carne de frangos de corte, desta maneira este estudo avaliou a influência da erva mate sobre a composição química e o perfil lipídico de carne de peito, coxas e sobrecoxas de frangos de corte. Foram utilizados 500 pintainhos de corte distribuídos em um delineamento inteiramente casualizado com inclusões de erva mate nas dietas (0.1; 0.2; 0.4, e 0.6%) com quatro repetições de 25 aves em cada tratamento, criados de 1 a 42 dias de idade para posterior abate e análises da composição de cortes cárneos. A adição de erva mate não afetou a composição química e o perfil lipídico dos peitos de frangos, porém a composição da carne de sobrecoxas foi afetada. Foi observado efeito da adição da erva mate em ácidos graxos saturados, insaturados, monoinsaturados e poli-insaturados na carne de sobrecoxas de frango, destacando-se a redução nas concentrações de ácidos graxos saturados e o aumento das concentrações dos ácidos poli-insaturados, em especial Linolênicoe Eicosapentaenoico, demonstrando assim o potencial da erva mate em alterar o perfil lipídico da carne de aves.

SUMMARY Yerba mate ( Ilex paraguariensis) has in its composition organic compounds wich can modify chemical composition of broiler meat. This study aimed to evaluate the influence of yerba mate in chemical composition and lipid profile of broiler breast and thigh meat. The trial was conducted using 500 broiler chicks distributed in a completely randomized design with four treatments (0.1; 0.2; 0.4, and 0.6%) and five replicates with 25 chicks each. The chicken were raised form 1 to 42 days old and slaughtered for analysis of breast and thigh meat. The addition of mate did not affect the chemical composition and the lipid profile of the chicken breast, however, the composition of the meat of thigh meat was affected. It was observed effect of the addition of the yerba mate to saturated, unsaturated, monounsaturated and polyunsaturated fatty acids in the chicken meat. Stands out the reduction in saturated fatty acid concentrations and the increase in the concentrations of polyunsaturated fatty acids, especially Linolenic and Eicosapentaenoic, thus demonstrating the potential of mate grass in altering the lipid profile of poultry meat.

As aflatoxinas são responsáveis por grandes prejuízos à saúde de aves comerciais e à produção animal, essencialmente por perda financeira decorrente de diminuição de ganho de peso dos animais. A detoxificação da ração ou de suas matérias-primas, bem como tentativas de diminuir a contaminação fúngica que leva à produção das toxinas, além de técnicas nutricionais, são métodos que podem ser adotados para tentar diminuir os efeitos deletérios sobre os frangos de corte. Sendo assim, o objetivo desta revisão é mostrar o que a ciência fornece como meios de detoxificação e/ou redução de contaminação por fungos; e algumas substâncias naturais que auxiliam a produção avícola na redução de micotoxicoses .

Aflatoxins are answerable for large losses for the health of commercial birds and for the animal production, essentially by financial losses due to animal body weight diminution. Detoxification of feed or its raw materials, well as attempts of diminution of fungal contamination that leads to toxins production, beyond of nutritional techniques, are methods that can be adopted trying to diminish deleterious effects among broiler chickens. This way, the objective of this review is to show what science supplies like ways of detoxification and/or reduction of contamination by fungi, and some natural substances that help poultry production on reduce mycotoxicosis.
