摘要
本试验主要探讨全混合日粮（TMR）对断奶后期犊牛生长发育的影响。试验选取40头3月龄断奶后体重、体型均一的健康母犊牛随机分为试验组（TMR饲养）和对照组（传统饲养），分别在4、5、6月龄进行体重和体尺的测量。结果显示，TMR对断奶犊牛的生长发育有加快的趋势，阶段末体重和日增重与对照组相比差异均极显著(P<0.01)；5、6月龄阶段犊牛体尺指标，与对照组相比影响达显著水平(P<0.05)，表明TMR饲喂模式比传统饲养更有利于断奶后犊牛早期生长发育。
Abstract
The objective of this study was to investigate the effects of total mixed ration (TMR) on the growth and development of female weaned healthy calves.A total of 40 female weaned healthy claves for the age of three month old in term of the same weaning weight and body size were selected and divided into experimental group (TMR feeder) and control group(traditional feeding) randomly. The body weight and size were measured at the end of 4, 5, and 6 months of age respectively. The results revealed that TMR feeding can increase the weight gain rate and development to weaning calf. There were signiifcant differences(P<0.01) within ifnal body weight and average daily gain between the experimental group and control group. Similarly, there was signiifcant differences(P<0.05) in body size between two groups. These results showed that TMR feeding mode was better than traditional feeding mode to the growth and development of female weaned healthy calves.
