13. Comparing the profitability of organic and conventional broiler production
Organic broiler chicken production has recently received more attention worldwide. This study carried out an economic analysis to compare the profitability of organic versus conventional growing systems per unit of broiler meat production. In this study, 400 slow-growing broilers (Hubbard Red-JA) were reared in an organic production system and the same numbe

15. Effects of feeding metabolite combinations from lactobacillus plantarum on plasma and breast meat lipids in Broiler Chickens
The effects of feeding different doses of metabolite combination of L. plantarum RS5, RI11, RG14 and RG11 strains (Com3456) on cholesterol reduction in plasma and breast meat in broiler chickens and the possible mechanism was studied. A total of 504 male Ross broilers were grouped into 7 treatments and offered with different diets: (i) standard corn-soybean

16. AvaliaÃÃo de biodigestor tubular na degradaÃÃo anaerÃbia de cama de frango de corte / Evaluation of tubular biodigester in anaerobic degradation with roiler litter
In the twenty-first century, the broiler production has increased in the world and continues increasing due to the high consumption of this meat. The broiler litter is the largest amount of waste generated in poultry production. It is also characterized by its high concentration of organic matter. The broiler production integrated system defines a radius aro

17. Lipid and selenium sources on fatty acid composition of intramuscular fat and muscle selenium concentration of Nellore steers
The objective of this study was to evaluate the effect of lipid and selenium sources in diets for finishing Nellore steers on the fatty acid composition and selenium concentration of the longissimus muscle. Fifty Nellore steers (body weight = 458±39 kg) were assigned to one of six dietary treatments: 1) diet containing sunflower seed and inorganic selenium;

18. Volatile compounds present in traditional meat products (charqui and longaniza sausage) in Chile
The aim of this work was to identify and quantify the volatile compounds in five different commercial brands of charqui and longaniza sausages. Volatile compounds were extracted from some samples headspace using solid phase microextraction (SPME). The identification and quantification were made through the gas chromatography with a mass-selective detector (G

19. Microbiological biodiversity in poultry and paddy straw wastes in composting systems
Immense quantity of waste is generated in association with poultry meat egg and crop production. The potential risks due to disposal of these wastes are magnified as a result of dense refinement of poultry production and the decreasing amount of land available for waste disposal. The study aims at studying the microbiological biodiversity of poultry waste an

20. Effects of copper sources and levels on performance, Cu status, ruminal fermentation, metabolism and oxidation of lipids in cattle / Efeitos de diferentes fontes e níveis de cobre no desempenho, "status" de Cu, fermentação ruminal, metabolismo e oxidação de lipídios em bovinos
Copper is associated with lipid metabolism, becoming very important in reducing cholesterol, and with oxidative stability of meat, because it is part of some antioxidant enzymes. However, when in the ionic form, is considered a pro-oxidant element. The organic copper did not exhibit this effect and, besides, presents higher bioavailability than inorganic sou

21. Tratamento de efluentes da indústria de processamento de carnes utilizando flotação por ar dissolvido e processos de oxidação avançada
The use of wastewater treatment processes with high efficiency of organic matter removal is considered one of the most important steps to achieve lower pollution loads in meat processing industries. As a primary treatment, dissolved air flotation processes (DAF) using coagulation-flocculation are generally applied. Additionally, the utilization of high effic

22. Supplementation effects of natural antioxidants on Brangus bovine tissues / Efeitos da suplementação de antioxidantes naturais em tecidos bovinos da raça Brangus
Twenty eight Brangus males were used to determine the oxidative stability of muscle and liver in order to compare organic and inorganic selenium source and rosemary extract based on the analysis of selenium concentration in the liver and in the serum, on the analysis of glutathione peroxidase, superoxide dismutase and catalase activities in the liver and als

23. Effect of components of the matrix in pesticide analysis by gas chromatography / Efeito de componentes da matriz na análise de agrotóxicos por cromatografia gasosa
This work aimed to systematically study the matrix effect on the measurement of pesticides chlorpyrifos, λ−cyhalothrin, cypermethrin and deltamethrin by gas chromatography with electron capture detector. The matrix effect is attributed to the presence of co-extractives in the organic phase during extraction. In this work, the phenomenon matrix eff

24. Desempenho, características da carcaça, perfil de ácidos graxos e parâmetros ruminais de ovinos alimentados com rações contendo polpa cítrica úmida semi despectinada e/ou polpa cítrica desidratada / Performance, carcass characteristics, fatty acids profile and ruminal measures in sheep fed diets containing wet low pectin citrus pulp and/or dried citrus pulp
The objective of this study was to evaluate the performance, fatty acids (FA) profile and ruminal measures of sheep fed citrus coproducts in diets containing high concentrate. Additionally, the performance and metabolic estimates from SRNS model - Small Ruminant Nutrition System were compared to experimental data. In Experiment I, 28 ewes were fed diet conta
