| Cento e oitenta poedeiras comerciais Isa Brown, com 60 semanas de idade, foram distribuídas em delineamento inteiramente ao acaso, em esquema fatorial 2 õ 2, com dois níveis de fitase (0 e 500 ftu/kg de ração) e dois de farelo de girassol (4 e 8%), totalizando cinco dietas, avaliadas com seis repetições de seis aves. As dietas foram formuladas a partir de uma ração controle, à base de milho e farelo de soja, isenta de fitase e farelo de girassol, valorizando na formulação das dietas a matriz nutricional da fitase. O período experimental foi dividido em quatro ciclos de 28 dias cada. A matriz nutricional preconizada para fitase permitiu o atendimento pleno das exigências das aves, mesmo quando as dietas foram formuladas com níveis nutricionais reduzidos,... |

| ABSTRACT The effect of additives used in the feed of broilers on anaerobic bio-digestion of poultry litter was evaluated. Four diets were used: NC: negative control; DFM: NC + 500 ppm direct-fed microbials (DFM) containing Bacillus subtilis and Bacillus licheniformis; ENZ: diet formulated with an enzyme blend (20 ppm phytase, 200 ppm protease and 200 ppm xylanase); DFM+E: ENZ + DFM. Substrates for the anaerobic bio-digestion were prepared with litter from each treatment, containing 4 % total solids (TS). These were used in 16 continuous bio-digesters with a 2 kg d−1 load, to determine the production and potential biogas production and composition during an 85-day period. Influent and effluent samples were collected for the amounts of TS and volatile solids... |

| ABSTRACT This study aimed to identify the influence of climate pattern and rearing conditions on broiler carcass condemnations observed during processing. We evaluated the registered data of 2015 from the federal inspection files in all broiler slaughterhouses located in the state of Mato Grosso do Sul, Midwestern Brazil. The percentages of condemnations by airsacculitis, cellulitis, dermatosis, ascites syndrome, total carcass condemnations, and average broiler weight at 42 days were analyzed. Data were associated with housing systems and season of the year in which each flock was reared. Two-way ANOVA was applied to the data in a completely randomized design 4×3 (four seasons and three houses) and compared by Tukey's test. The results indicated that the... |

| Um experimento foi realizado para avaliar o desempenho e a composição da cama, das tíbias, do fígado e das excretas de frangos de corte em diversas fases utilizando-se diferentes níveis de fósforo disponível (Pd) e da enzima fitase. Foram utilizados 1.200 pintos machos de 1 dia de idade, da marca comercial Cobb, distribuídos em delineamento inteiramente casualizado, em esquema fatorial 4 × 3, composto de quatro níveis de fósforo disponível e três níveis de fitase: 0, 500 e 1.000 ftu/kg de ração, cada um com quatro repetições de 25 aves. Os níveis de fósforo disponível foram obtidos considerando quatro disponibilidades do fósforo total (Pt) do milho e do farelo de soja (34, 56, 78 e 100% de disponibilidade). Foram avaliados os índices de desempenho no final... |

| ABSTRACT The objective of this study was to evaluate the effect of chamomile extract on Japanese quail on their performance, animal behavior, tonic immobility, body injuries, and surface temperature. The trial was conducted using 108 quail distributed in a completely randomized experimental design, with three treatments (0, 2.5, and 5.0 g chamomile/kg of feed), six replicates, and six birds per treatment, evaluated in six measures repeated in time (14, 28, 42, 56, 70, and 84 days of trial). The inclusion of chamomile presented a quadratic effect on sitting behavior, estimating the inclusion of 1.8 g chamomile/kg to maximize this behavior. There was a decreasing linear effect for aggressive pecking, that is, the higher the inclusion of chamomile in the... |

| ABSTRACT Different levels of glycosaminoglycans (chondroitin sulfate and glucosamine sulfate) and vitamin C were injected in ovo to determine whether additive use influences the incubation parameters and bone characteristics of posthatch chicks. Hatchability was not affected by addition of glycosaminoglycans and vitamin C in ovo. However, chicks that received 4 μg additive showed 2.86% reduction in total mortality when compared with chicks from non-injected eggs. Moreover, tibia area and femur bone mineral density increased in chicks from eggs injected with 2.16 and 6.00 μg of additive, respectively. In ovo feeding with glycosaminoglycans and vitamin C can benefit bone development in embryos and reduce total mortality during the incubation period. |
