不同因素颗粒饲料对湖羊羔羊育肥的效果比较

Comparison of Fattening Effects of Pellet Feed with Different Factors on Hu Lamb

为进一步验证不同因素颗粒饲料在实际生产中的具体应用效果,按照同质原则选择30只湖羊羔羊,按照随机原则将其划分为3个组别,每个组别10只羔羊。试验1组羔羊饲喂颗粒化的全混日粮,试验2组饲喂散装的全混日粮,对照组采用精粗饲料分开饲喂方式,正式试验期为30 d。结果表明,试验1组和试验2组相对于对照组平均日增重分别增加4.76、0.92 g,其中以试验1组的增重最为明显,组间对比差异性显著(P<0.05)。试验1组、试验2组和对照组的料重比分别为(3.16±0.14)、(4.28±0.15)、(4.49±0.31),组间对比差异性显著(P<0.05)。进一步计算发现试验1组羔羊每增重1 kg需要的成本比试验2组和对照组降低1.50元和1.81元。研究结果表明,颗粒化全混日粮在湖羊羔羊育肥方面有显著的效果,在今后养殖中值得推广应用。

In order to verify the application effect of pellet feed with different factors in actual production,30 Hu lambs were selected according to the homogeneity principle,and were divided into 3 groups according to the random principle,each group has 10 lambs.In the experiment,1 group of lambs were fed granulated total mixed diet,2 groups were fed bulk total mixed diet,and the control group were fed refined roughage separately.The results showed that the average daily gain of test 1 group and test 2 group was 4.76 g and 0.92 g higher than that of control group,and the weight gain of test 1 group was the most obvious,the difference between the two groups was significant(P<0.05).The material weight ratio of test group 1,test group 2 and control group were(3.16±0.14),(4.28±0.15)and(4.49±0.31)respectively,the difference between the groups was significant(P<0.05).Further calculation showed that the cost per kg weight gain of lamb in group 1 was 1.50 yuan and 1.81 yuan lower than that in group 2 and control.The results showed that pelleted total mixed ration had significant effect on fattening Hu lamb,and it was worth popularizing and applying in the future.
