13. Spatial dependence of attributes of rainfed maize under distinct soil cover conditions
RESUMO O cultivo de milho em sequeiro é amplamente explorado no Nordeste Brasileiro pela agricultura familiar, para alimentação humana e animal. Para melhorar a captação da água da chuva e a umidade do solo, pode-se adotar a cobertura morta, embora essa prática ainda seja raramente aplicada no cultivo de milho de sequeiro. Neste contexto, o objetivo d

14. Crossbreeding locally adapted hair sheep to improve productivity and meat quality
ABSTRACT: The use of lambs from crossing of local with specialized sheep breeds for meat production may lead to higher meat deposition and a smaller fat amount in the carcass, with a more adequate nutritional profile for human consumption. This study investigated the performance, carcass and meat characteristics of lambs from the Morada Nova and Santa Inês

15. Application of computational fluid dynamics on a study in swine facilities with mechanical ventilation system
ABSTRACT: Ventilation systems used in swine facilities deserve to be studied because they directly affect productivity in the pig farming sector. Bearing this in mind the uniformity of air distribution and temperature is essential to animal welfare in this breeding environment. Thus, the purpose of this study was to identify whether changes in air entrances

16. Inclusion of Moringa Leaf Powder (Moringa oleifera) in Fodder for Feeding Japanese Quail (Coturnix coturnix japonica)
ABSTRACT This research evaluated the nutritional, nutraceutical, antimicrobial, as well as the growing promoter effect of Moringa oleifera (MOR) leaves flour in fodders for fattening Japanese quails. The antimicrobial activity was measured using the method of Kirby-Bauer. A completely random design with 4x2 factorial arrangement was used, fodders included 0,

17. Presence of roosters in an alternative egg production system aiming at animal welfare
ABSTRACT The objective of this study was to evaluate the effect of the presence of roosters on welfare and egg production of laying hens reared in an alternative system. Two breeding systems were established: barn 1 - laying hens reared without roosters (4500 birds); and barn 2 - laying hens reared with roosters (4500 layers and 250 roosters). In the poultry

18. Lactobacillus plantarum BL011 cultivation in industrial isolated soybean protein acid residue
Abstract In this study, physiological aspects of Lactobacillus plantarum BL011 growing in a new, all-animal free medium in bioreactors were evaluated aiming at the production of this important lactic acid bacterium. Cultivations were performed in submerged batch bioreactors using the Plackett-Burman methodology to evaluate the influence of temperature, aerat

19. SOWS AND PIGLETS THERMAL COMFORT: A COMPARATIVE STUDY OF THE TILES USED IN THE FARROWING HOUSING
ABSTRACT The global animal production is increasing as expected to meet world demand for food, especially for meat products. This research aimed to investigate the effect of two types of roofs (clay and fiber-cement tiles) in a tropical area on the thermal comfort of farrowing sows and piglets. Twelve sows and forty-eight piglets were observed during summer

20. SUSTENTABILIDADE NO USO DO FÓSFORO: UMA QUESTÃO DE SEGURANÇA HÍDRICA E ALIMENTAR
The phosphorus used as fertilizer in agriculture is extracted from phosphate rocks, which after extraction reacts with sulfuric acid, releasing phosphoric acid, a raw material for the fertilizer industry. Studies point to a possible depletion of world reserves of phosphate rock in the next 50-100 years. A phosphorus scarcity is closely linked to global food

21. Lighting in the shackling area: conciliating broiler welfare with labor comfort
The objective of this study was to investigate if blue lighting could reduce broiler stress and comply with legal labor comfort requirements in a new shackling area of a middle-size processing plant. In this study, the old shackling area was compared with the new area, where a blue lighting system was designed and implemented according to the regulations. Th

22. Extracellular polysaccharide production by a strain of Pleurotus djamor isolated in the south of Brazil and antitumor activity on Sarcoma 180
Polysaccharides with medicinal properties can be obtained from fruiting bodies, mycelium and culture broth of several fungus species. This work was carried out in batch culture using a stirred tank reactor with two different initial glucose concentrations (40-50 g/L) and pH values (3.0-4.0) to enhance extracellular polysaccharides production by Pleurotus dja

23. Prebiotic inulin: Useful dietary adjuncts to manipulate the livestock gut microflora
In recent years, there has been a growing appreciation on the relevance of gastrointestinal microflora in both ruminants and non-ruminants owing to revelation of their role in several physiological functions including digestion, nutrient utilization, pathogen exclusion, gastrointestinal development, immunity system, gut gene expression and quality of animal

24. MODELO COMPUTACIONAL DE PRODUÇÃO PARA AFERIÇÃO DE LACTAÇÃO EM CABRAS / COMPUTER MODEL OF PRODUCTION FOR MEASUREMENT OF LACTATION IN GOATS
A caprinocultura leiteira no Brasil enfrenta uma série de desafios na melhoria de sua produtividade. Os baixos investimentos, a pouca receptividade do mercado interno e a falta de informatização nas pequenas propriedades são desafios a serem vencidos. Devido a restrições fisiológicas, animais produtores de leite não produzem de forma contínua, haven
