研究在阿勒泰羊日粮中添加棉副产品的适宜添加量及棉副产品对阿勒泰羊生产性能和血液指标的影响。选用体重约25k的雄性阿勒泰羊40只，分成4组（对照组、试验组1、试验组2和试验组3），分别在日粮中添加不同含量棉酚的棉副产品，棉酚含量分别为0、200、300、400ppm。定期称重并计算日增重、产粪量，对血液部分矿物元素进行测定。结果表明，在第21～40天，试验组3体重和日增重均为最高，与对照组相比差异显著（P〈0．05），试验组3与试验组1日增重差异显著（P〈0．05），但在第41～60天，试验组3日增重下降，甚至个别羊出现负增长，试验组3在第1～60天的日增重最低。第1～20天和第21～40天，试验组3和试验组2采食量均与其他两组均差异极显著（P〈0．01），但在第41～60天，试验组3与试验组2和试验组1相比均差异显著（P〈0．05），与对照组相比差异极显著（P〈0．01）。随着时间的延长，除试验组3有下降趋势外，其他组采食量变化不显著，稳中有升（P〉O．05）。在第1～20天，对照组DM消化率与其他组均为差异极显著（P〈0．01），试验组2和试验组1均与试验组3差异显著。在第21。40天，对照组与试验组3相比差异极显著（P〈0．01），与试验组2相比差异显著（P〈0．05）。添加棉酚可提高血清镁的含量，血清钙含量有下降趋势，血清磷含量有上升趋势。试验结果表明，短期饲喂高棉酚含量的棉副产品可以促进阿勒泰羊的日增重，但长期饲喂（60d）高棉酚含量（400ppm·d^-1）的棉副产品影响日增重和采食量，添加不同棉酚含量的棉副产品，阿勒泰羊可提高血清镁的含量；血清钙含量有下降趋势，血清磷含量有上升趋势。

To study suitable amount of cotton by-product, and cotton by-product in the Altay sheep diets, and the effect of the Altay sheep production performance and blood parameters, the present experiment was designed to feed cotton by-product to 40 male Ahay sheep, weight of about 25 kg, respectively divided into four groups, in diets supplemented with different levels of gossypol cotton by-product, weighing and calculation of daily gain, the amount of manure produced, some mineral elements in the blood were measured. The results showed that, in the first 21-40 d, the test group three body weight and daily gain were highest were significantly different to the control group（P〈0.05）, the test group three and test groups one were significant difference in daily gain（P〈0.05）, but in the first 41-60 d, the test group three daily gain decreased or even negative growth of individual sheep, the test group three in the first 1-60 d of the lowest daily gain. Section 1-20 d and 21-40 d, the test group three and test groups two feed volume were significantly different to the other two groups（P〈0.01）, but in the 41-60 d, the test group three and test group two were significantly different to test group one（P〈0.05）, and was significantly different with the control group （P〈0.01）. With time, in addition to the downward trend in the experimental group three, the other group feed intake did not change significantly, steadily. In the first 1-20 d, the control group, DM digestibility and other groups were significantly different （P〈0.01）, the test group two and test group one were significantly different to test group of three. In the first 21-40 d, the control group and test group of three significantly different, with significant differ-ences in the test group two. Add gossypol, increased serum levels of magnesium; a downward trend in serum calci-um, serum phosphorus levels rise.
