摘要:

旨在研究不同月龄断奶应激对马驹血清指标和体增重的影响,以确定马驹断奶的最佳时间。选用15匹英纯血马驹和它们的母马,根据马驹的月龄分成3组,每组5匹;采用突然断奶法将马驹与母马分离,测定马驹断奶前、断奶当天和断奶后10个血清指标并称重,应用R语言进行数据分析。结果表明:断奶当天所有马驹葡萄糖(GLU)都显著高于断奶前后(P<0.05),断奶当天8月龄断奶马驹的葡萄糖(GLU)含量最高,6月龄断奶马驹最低(P<0.05);从断奶当天到断奶后的日增重值变化可知6月龄断奶马驹日增重值最高(0.78±0.05 kg),8月龄马驹日增重值最低(0.13±0.52 kg)。综上表明,采用突然断奶法,相比7、8月龄断奶,6月龄断奶马驹应激程度较小,体重增加较快。

Abstract:

In this study,the effects of weaning stress on blood serum index and body growth at different ages foals were investigated to get the best weaned time.A total of 15 Thoroughbred mare-foal pairs were divided into 3 groups(each group,n=5) according to the weaning age.Foals and mares were separated by using the abrupt-weaned method,the changes of 10 blood serum biochemical indices and body weight of foals were measured on pre-weaning day,weaning day and post-weaning day.The results showed as follows:The concentrations of GLU in all foals on weaning day more significantly increased than those on pre-weaning day and post-weaning day(P<0.05).On weaning day,the concentration of GLU for 8-month foals was the highest and that of 6-month foals was the least(P<0.05).The daily weight gain of 6-month foals was the highest(0.78±0.05 kg) and that of 8-month foals was the least(0.13±0.52 kg) from weaning day to post-weaning day.Results of the present study indicated that 6-month foals had less weaning stress and rapid weight gain compared with 7-month and 8-month foals by using the abrupt-weaned method.
