黑麦在鸡体内的消化性研究

Study on Digestibility of Tow Rye Feedstuffs HH91 and Pluto in Chicken

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）。

Abstract:

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 detected 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.
