摘要
采用断乳前补饲和逐渐断乳法对比断乳对牦牛犊牛生长的影响。试验随机选择20头犊牛分成两组,试验组在断乳前适当补饲,对照组无任何补饲。结果显示试验组犊牛在断乳后体重持续增长,增长了14.09kg,而对照组犊牛在断乳后体重持续下降,比断乳前降低了8.20kg。结果表明,牦牛犊牛断乳前进行补饲可以减少断乳对犊牛发育的影响,有利于犊牛后期的生长发育。
The effects of pre-weaning supplementation and gradual weaning on the growth of yak calves were compared. Twenty calves were randomly selected and divided into two groups. The experimental group received proper supplementary feeding before weaning, while the control group received no supplementary feeding. The results showed that calves of the experimental group continued to gain weight after weaning, increasing by 14.09 kg, while calves of the control group continued to lose weight after weaning, decreasing by 8.20 kg compared with before weaning. The results showed that supplementary feeding before weaning could reduce the influence of weaning on the calf development and was beneficial to the growth and development of the calf.
