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.
