早期断奶对舍饲福清山羊羔羊生长性能和血清生化指标的影响

Effect of Early Weaning on Growth and Serum Indices of Fuqing Goats

  • 摘要: 为研究舍饲福清山羊早期断奶的育肥效果,分别测定早期断奶和自然断奶(CK)处理羔羊150日龄内的生长性能和35日龄血清生化指标。结果表明:早期断奶处理在15~30日龄的平均日增重极显著低于自然断奶处理(P < 0.01),但60、90、120和150日龄的平均日增重均高于自然断奶组,其中120日龄到150日龄之间的平均日增重极显著高于自然断奶组(P < 0.01);早期断奶组全期平均日增重极显著高于自然断奶组(P < 0.01),150日龄羔羊平均体重比自然断奶高2.3 kg(P < 0.01)。除血糖外,早期断奶和自然断奶35日龄羔羊的其他6项血清生化指标均无显著差异(P > 0.05),自然断奶组血糖含量极显著高于早期断奶组(P < 0.01)。本研究表明舍饲福清山羊实施早期断奶可促进其快速育肥生产。

     

    Abstract: An experiment was conducted in an indoor barn to determine the effect of early weaning on the growth performance of Fuqing goats from birth to 150-day-old and the serum indices when they were 35-day-old. The results showed that the average daily gain (ADG) in 15 to 30 days of the early weaned goats was lower than that of the naturally weaned counterparts (P < 0.01). The ADG became higher as these early weaned goats grew to 60 to 150-day-old and was extremely significantly higher in 120 days and 150 days (2.3 kg heavier) (P < 0.01) than the naturally weaned ones. The serum urea nitrogen, total protein, albumin, total cholesterol, calcium and phosphorus were not significantly different between the groups of young goats. However, the early weaned goats had a lower serum glucose level than their counterparts (P < 0.01). The results suggested that early weaning might accelerate the growth of newborn Fuqing goats.
