摘要
采用颗粒全混合日粮（TMR）与精粗分饲两种饲养方式进行山羊育肥试验。结果表明,颗粒TMR饲养波尔山羊与地方马头山羊,平均日增重均达到120 g/只以上,精粗分饲平均日增重为58.5 g/只,颗粒TMR较精粗分饲试验期增重收益高57.8元/只以上,使用颗粒TMR饲养方式优势明显。不同精粗比颗粒TMR对马头山羊和波尔山羊育肥试验结果表明,高精粗比（5∶5）波尔山羊组日增重为（152±21.94）g,料重比为6.24∶1,其日增重显著高于其他各试验组（P〈0.05）,试验期增重收益较其他组高24.3~31.6元/只;高精粗比（5∶5）马头山羊组与低精粗比（4∶6）波尔山羊组和马头山羊组之间日增重差异不显著（P〉0.05）,增重期收益无明显差异。
Two feeding modes such as total mixed ration （TMR） and conventional concentrated feed with roughage were conducted in two breeds of fattening goats. The results showed that the average daily gain （ADG） of Matou goats and Boer goats by TMR feeding mode were above 120 g,while in conventional concentrated feed with roughage mode were 58.5 g.The profit from weight gain in TMR feeding mode were higher than conventional concentrated feed with roughage by at least 57.8 yuan per goat and presented obvious advantages. The test of TMR with different forage ratio for fattening Matou goats and Boer goats showed that the ADG of Boer goats in high forage ratio （5：5） group was （152±21.94） g which was significantly higher than other groups （P〈5%）.And its feed conversion ratio was 6.24：1,its weight gain profit during the test were higher than other groups from 24.3 to 31.6 yuan per goat.It showed no significant difference in ADG and weight gain profits among the other three groups such as Boer goats in low forage ratio（4：6） and Matou goats group in high and low forage ratio （P〉5%）.
