摘要
本试验旨在研究不同精粗比全混合颗粒日粮和全混合日粮(TMR)对湖羊育肥生产性能及血液生理生化指标的影响,探索湖羊全混合颗粒饲料的配制技术和使用效果。结果表明:全混合颗粒饲料育肥体重约30kg湖羊,平均日增重192~201g/d,精粗比5∶5、4∶6、3∶7的全混合颗粒日粮组间平均日增重差异不显著(P﹥0.05),但均高于TMR组,精粗比3∶7的全混合颗粒日粮组日增重(201g/d)著显高于TMR组(158g/d)(P<0.05);湖羊生理生化指标均处于正常范围内。综上,湖羊全混合颗粒日粮适宜精粗比为3∶7。
This experiment was to study different fine coarse than mixed grain diet and TMR(total mixed ration) for sheep fattening production performance and the influence of blood physiological and biochemical indexes,aimed to explore the preparation technology and use effect of sheep full mixed grain feed. The results showed that the hybrid granule feedstuff fattening about 30 kg weight sheep,average daily gain of 192 ~ 201 g/d,the average daily gain in fine coarse than 5∶5,4∶6,3∶7 mixed grain diet groups were not significant difference(P﹥0.05),but the daily gain were higher than in TMR group,fine coarse than 3∶7 mixed grain diet group were significantly higher than that of TMR group(P < 0.05). The physiological and biochemical indicators of sheep were within normal range. The above indicators suggested that the total mixed grain ration of the lake sheep was 3:7.
