Effects of Different Raising Ways on the Early Growth and Development Performance of Nanjiang Yellow Goat

摘要

A total of 106 two month-old Nanjiang yellow goats (male were 32, female were 34 and castrated were 40) were divided into treatment group and control group to determine the growth performance. The treatment group was reared in grazing mode, experimental group was pastured with supplement feeding. The results showed that the body weight of male in experiment group was heavier by 9.82%(P<0.05) ,11.87%(P<0.01), 16.91%(P<0.01) and 23.99%(P<0.05) than that in control group in 3,4,5 and 6 month-age. The body weight of female in experimental group was heavier by 11.54%(P<0.05), 13.79%(P<0.01), 17.47%(P<0.01) and 21.15%(P<0.01) than that in control group in 3,4,5 and 6 month-old. The body weight of castrator in experimental group was heavier by 1.58%, 1.99%, 13.08%(P＜ 0.01) and 15.76%(P<0.01) than that in control group in 3,4,5 and 6 month-age. The daily increasing weight and body measurements of experimental group is improved more than control group, especially in 6 month-age.
