【摘要】 选用6头110～120日龄、体重相近的北京黑猪生长母猪,进行两次消化试验,用4N—HCI(盐酸)不溶灰分法测定各营养成分的消化率。试验结果表明,猪对初花期籽粒苋粗蛋白的消化率为71.44％,粗纤维21.67％,消化能为11.01MJ/kg干物质,同其他青绿饲料类相比,猪对初花期籽粒苋的蛋白质消化率较高,粗纤维的消化率较低,消化能较高。初花期籽粒苋不失为猪的良好青绿饲料。更多还原

【Abstract】 The results of digestion trial showed that the digestibility of grain amaranth nutri-ents for growing pigs respectively was 71.44% (Cp), 21.67% (Cf), 24.32% (EE), and71.27% (NFE). The digestible energy of grain amaranth for pig was 11.01MJ/kg·DM。It is a good feeds for pigs.更多还原
