摘要：

Sixteen growing male castrate indigenous goats (20 months old, average liveweight 17+/-4.5 kg) were divided into four groups of four goats each and fed diets based on Katambora Rhodes Grass (Chloris gayana) hay and maize containing either 0, 11, 22 or 33% crushed whole soybean (diets I, II, III and IV, respectively) for 30 d of which 23 were adjustment days and 7 d collection period. Apparent nutrient digestibility and nitrogen balance were determined from d 24 to 30. Digestibility of crude fibre was less (P<0.05) for goats fed diets III and IV than for those fed diets I and II. This effect appeared to be related to the percentage of soybean (crude fat) in the diets. Digestibility of crude fat rose as percentage soybean increased, with diet IV having a greater (P<0.05) crude fat digestion coefficient than the other three diets. Apparent digestibility of crude protein was greater (P<0.05) with diets III and IV, than with diets I and II. Nitrogen balance was positive in all four groups and increased as the percentage of soybean in the diet increased.
