| Objetivou-se avaliar o desempenho, a resposta imune e as características de carcaça de frangos de corte alimentados com dietas suplementadas com cromo complexado a levedura (Saccharomyces cerevisae), criados em diferentes condições de temperatura. O experimento foi conduzido em câmaras climáticas com sistema de aquecimento e refrigeração, utilizando-se as seguintes condições de temperatura, de acordo com as idades: 1 a 3 dias (35, 35 e 35 ºC ± 2), 4 a 7 dias (35, 30, 25 ºC ± 2), 8 a 14 dias (34, 27 e 20 ºC ± 2), 15 a 21 dias (33, 26 e 18 ºC ± 2) e de 22 a 47 dias (32, 26 e 18 ºC ± 2), respectivamente, para temperatura quente, termoneutra e fria. As dietas foram suplementadas com 0, 400, 800, 1.200 μg Cr/kg. A suplementação de 400 μg Cr/kg melhora a... |

| ABSTRACT: The present research was conducted to evaluate whether different beak trimming methods and rearing systems affected the feed selectivity of laying hens. A total of 178 Hy-line Brown laying hens in the growing phase and 120 hens in the production phase were divided in a factorial arrangement (2 x 3), with two rearing systems (floor and cages) and three beak trimming methods: without beak trimming (control), hot-blade beak trimming, and infrared beak trimming, with four replicates. Laying hens were feed with isonutritive diets. Samples were collected from feed orts and feed provided, with a subsequent analysis of dry matter, crude energy, crude protein, mineral matter, geometric mean diameter and geometric standard deviation. The results were... |

| Eggs are perishable foods and lose quality quickly if not stored properly. From the moment of posture to the marketing of egg, quality loss occurs through gas exchange and water through the pores of the shell with the external environment and thus, studies involving modified atmosphere packaging are extremely important. The aim of the present study is to assess the internal quality of eggs packed under modified atmosphere and stored at room temperature. Six hundred and twelve fresh commercial eggs from 38-week old Hisex White laying hens were used. The present study was conducted in a completely randomized experimental design in a 4 x 4 + 1 factorial arrangement [vacuum, vacuum with oxygen gas (O2) absorbent, vacuum with oxygen gas (O2) and carbon dioxide... |

| Qualitative characteristics of breast meat of broilers fed diets supplemented with different concentrations (0; 0.3 and 0.5mg kg-1) of selenium in the form of selenomethionine and sodium selenite were analyzed. A total of 1050 one-day-old male Cobb broiler chicks were arranged factorially at random to five treatments (two concentrations x two sources + control diet without addition of selenium) with 7 replications of thirty birds each and received an isonitrogenous and isocaloric diets in all phases according to their ages (1-21, 22-35, and 36-42 days). At 42 days of age, TBARS (thiobarbituric acid reactive substances) after storage at 4ºC for one, seven and 15 days and also after 30 days under freezing temperatures (-15°C), color (CIELab), water holding... |
