| Resumo: |
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 Universidade Federal do Paraná. Feed form did not affect the coefficient of total intestinal tract apparent digestibility of DM, N or crude fat (CF); however, an increase in corn particle size improved the coefficient of total intestinal tract apparent digestibility of DM, N and CF. AME and AMEn were not affected by treatments. Feed form does not affect nutrient digestibility on young turkeys and grinding corn at an average particle size bigger than 380 µm improves nutrient digestibility.
