膨化蓖麻粕的饲用

Extruded Castor-seed Meal for Feed

摘要:

用强饲法测定膨化蓖麻粕的鸡代谢能和真可消化氨基酸 .在此基础上 ,进行肉用仔鸡和生长猪的饲养试验 .试验结果 :膨化蓖麻粕的鸡代谢能为 9.2 9MJ/kg ,各种氨基酸消化率为 :Asp86.7% ,Thr 77.3 % ,Ser 81 .1 % ,Glu 90 .0 % ,Gly 54.2 % ,Ala 78.5% ,Cys 82 .9% ,Val83 .2 % ,Met80 .2 % ,Ile 83 .2 % ,Leu 81 .3 % ,Tyr 79.6% ,Phe 84 .4 % ,Lys 74 .3 % ,His 90 .5% ,Arg 92 .3 % .肉鸡饲养试验表明 ,前、中、后期分别加 3 %、6%、9%的膨化蓖麻粕对肉鸡生长无不良影响 .生长猪试验表明 ,前期加 5%的膨化蓖麻粕对猪无不良影响 ,后期加 1 6%的膨化蓖麻粕对猪的生长也无不良影响 .以上结果表明 ,膨化蓖麻粕是一种营养价值良好的饲料资源 .

Abstract:

Force feed trials were conducted to estimate the metabolism energy and true digestibility of amino acids of extruded castor seed meal(ECM) for chick. And then, two performance trials were conducted to estimate the feed value of ECM for broiler chicken
