The objective of this study was to evaluate bird responses to flavophospholipol at higher doses than those recommended by the Brazilian legislation. A trial was conducted with 900 male broilers divided into five doses of flavophospholipol: 0, 2, 4, 8 and 16 mg/kg. The performance evaluation was conducted weekly until 42 days of age. The evaluated parameters were: weight gain, feed conversion corrected for mortality, feed intake and mortality. At the end of experimental period, birds supplemented with growth promoter differed from the negative control for weight gain and feed conversion in the period from 1 to 42 days. Body weight gain and feed conversion were significantly higher for birds fed 16 mg/kg of flavophospholipol, compared with treatment without... |

A digestibility trial with 16 to 21-day-old turkeys was conducted to study the effects of feed form and corn particle size on the coefficient of total intestinal tract apparent digestibility of dry matter (DM), nitrogen (N), ether extract (EE), aparent metabolizable energy (AME) and aparent metabolizable energy corrected by nitrogen balance (AMEn). A completely randomized experimental design in a 2 × 3 factorial arrangement - two feed forms (crumble and micropellet) and three average particle sizes of the corn (380, 606, 806 µm) - was applied. Three hundred and sixty 1-d-old B.U.T 9 male turkey poults were distributed into 36 cages, 6 replications of 10 birds, each one per treatment. Overall care of birds complied with welfare directive from the... |

Avaliaram-se as características reprodutivas de duas raças puras de poedeiras semipesadas. Foram utilizadas 800 fêmeas, 400 da raça Plymouth Rock White (PRW) e 400 da raça Plymouth Rock Barred (PRB) no período compreendido entre a 16ª e a 24ª semanas de idade, quando todas as aves tiveram o mesmo manejo e receberam água e ração ad libitum. Semanalmente, foram mensurados os parâmetros peso corporal, consumo alimentar, taxa de postura, conversão alimentar, peso dos ovos, peso de oviduto e número de folículos ovarianos. Foi utilizado um delineamento inteiramente casualizado (DIC) com dois tratamentos (PRW e PRB) e cinco repetições de oitenta aves cada, sendo que os dados foram submetidos à análise de variância e as médias comparadas pelo teste "T" de Student... |
