长毛兔日粮营养水平对日粮中养分消化率的影响

THE INFLUENCE OF NUTRITIVE LEVELS OF ANGORA RATION ON THE DIGETIBLE RATE OF NUTRIENTS IN IT

选用176只德系安哥拉成年毛兔,分4期对22组日粮进行了消化试验,提出并验证十余种常用毛兔饲料原料的消化能值及8个有关能量及营养物质消化率的回归方程。结果表明:日粮能量,粗纤维、粗脂肪的消化率随CF的上升而递减,随DE的上升而递增,而与CP无关;DCP不受 DE、CFat含量的影响,仅随其本身含量的上升而递增;必需AA也呈类似的趋势。本试验以CF10％,DE12.55MJ/kg,CP18％时消化率为最高。

176 German Angora Rabbit were divided into 22 groups in 4 digestion experiments.The results show 1) The digestio of the energy, crude fibre, crude fat is in negative relation to. and is in possitive ation to the digestible energy, and isn't influenced by theThere is influence of the energy, crude fibre, crude fat of the diets on CP is affected by CP of the diet. 3) The digestibility of thetial a vs and Met+Cys, are in positive correlation to the content of Cys.
