Resumo
Four assays were carried out to determine the apparent metabolizable energy (AME) and nitrogen corrected
apparent metabolizable energy (AMEn) of ten feedstuffs of vegetable origin for poultry at different ages. The chemical
composition of the ten feedstuffs was also determined: 45% soybean meal, 48% soybean meal, extruded full-fat soybean,
deactivated full-fat soybean, micronized full-fat soybean, deactivated soybean meal, soybean protein concentrate, corn gluten
meal 21%, corn germ and broken rice. The method of total excreta collection was used and a randomized complete experimental
design was used with 11 treatments and six replications, in the four assays. In the 1st, 2nd and 3rd assays broiler chicks were
used aged 10 to 17, 26 to 33 and 40 to 47 days, respectively, and in the 4th assay roosters were used with 25 weeks of age.
The AMEn values (as-fed basis) determined in the 1st, 2nd, 3rd and 4th assay were, respectively: 2069, 2148, 2272 and 2231
for 45% soybean meal; 2214, 2225, 2319 and 2247 for 48% soybean meal; 3322, 3331, 3405 and 3493 for extruded full-fat
soybean; 3016, 3067, 3139 and 3388 for deactivated full-fat soybean; 3557, 3638, 3828 and 3869 for micronized full-fat
soybean; 2292, 2348, 2518 and 2502 for deactivated soybean meal; 2356, 2399, 2509 and 2486 for soybean protein
concentrate; 1826, 1882, 2110 and 1942 for corn gluten meal 21%; 2605, 2764, 2925 and 2832 for corn germ; and 2967,
3029, 3096 and 3026 for broken rice.
