摘要
分别研究了鸡对两种黑麦HH91和Pluto的消化性。实验结果表明:饲喂分别添加两种黑麦日粮实验鸡的日增重有减少的趋势,增重变化率和对照组比较分别是27.41%(15%HH91)、28.96%(30%HH91)、34.75%(45%HH91)、20.85%(15%Pluto)、28.19%(30%Pluto)和42.09%(45%Pluto)。而添加了黑麦的日粮干物质、有机物、粗蛋白、粗灰分、无氮浸出物、总能的表观消化率与正常对照组相比没有明显的差异(p>0.05),但粗脂肪和粗纤维的表观消化率有明显减少的趋势(p<0.05)。其次,在两种黑麦添加量低于30%时,除粗纤维的表观消化率之外,其余营养成分的表观消化率与正常对照组几乎没有差别(p>0.05)。
The digestion and metabolism experiment was carried out on the basis of HH91 and Pluto rye in chicken. The results showed that average weight gain of chickens had a decreasing tendency compared with the control. The detectexi average weight gain （the control） were 27.41% （15% HH91）, 28.96% （30% HH91）, 34.75% （45% HH91）, 20.85% （15% Pluto）, 28.19% （30% Pluto） and 42.09% （45% Pluto）, respectively. There was no difference （p〉0.05） in the apparent digestibility of dry matter, organic material, crude protein, nitrogen-free extract, and gross energy between the control and the other groups administrated with rye. But the apparent digestibility of crude fat and crude fiber had a decreasing tendency （P〈0.05）. No significant differences were found in other aspects except crude fat （p〈0.05） and crude fiber （p〈0.01）. When the addition of rye was less than 30%, all the apparent digestibility of the nutrients had almost no difference with the control group except that of the crude fiber.
