Abstract

Proximal analysis, minerals, aminoacids, digestible dry matter (DDM). crude protein digestible coeficient (CPD), digestible energy (DE) and metabolizable energy (ME) of 21 ingredients utilized in swine nutrition were determined by metabolism assay. One hundred sixty eight Landrace x Large White barrows were used beign 84 with 29.3 ± 0,6 kg and 84 with 69.7 ± 0.5 kg. The method of total feces collection was used. The digestibility value of several feeds were influenced by the weight of the barrows. The average value of DE and ME (kcal/kg), expressed on dry matter basis were respectively: alfafa hay €” 2334 and 1965; babaçu nut meal €” 2254 and 2127; raw sweet potato 3272 and 2879; cashew nut €”3665 and 3432; cashew nut pulp €” 1664 and 1539; fresh sugar cane juice €”3993 and 3817; raw €œcara€ (Dioscorea alata) €” 3190 and 2958; bovine meat and bone meal €” 2734 and 2439; coconut meal €” 3433 and 3334; methyl esteres of soybean fatty acids €” 8458 and 7940; chicken fatty €” 7422 and 6942; lecithin soybean raw €” 7944 and 7149; dehydrated soybean milk €” 4892 and 4632; cassava scraps €” 3433 and 3134; corn starch €” 3951 and 3721; ground corn €” 3975 and 3629; ground corn cob €” 3226 and 2923; corn grain silage €” 4093 and 3809; autoclaved bone meal €” 828 and 688; fish meal 3989 and 3753 and soybean fatty acids residues €” 7252 and 6950.
