摘要
为了探究在犊牛饮奶早期采用代乳粉替代鲜奶是否可行,开展了本试验。在60 d的试验期内,对照组的犊牛一直饲喂鲜奶,试验组的犊牛饲喂2 d的初乳后,经过6 d的过渡期,从第9 d起全部饲喂代乳粉,两组犊牛每顿饲喂乳品的量保持相等。试验结果显示:试验组犊牛的腹泻率较对照组降低了25%,平均断奶重及平均日增重与对照组相比分别提高了4.70 kg、81 g,差异均达到显著水平(P<0.05);通过成本分析,试验组每头犊牛能节约575元的饲养成本。可见采用代乳粉早期替代鲜奶饲喂犊牛是可行的。
In order to explore whether it was feasible to use milk replacer substituting milk to feed calves, this experiment was researched. Within 60 days of the experimental period, the calves in control group were fed with milk, while the calves in test group were fed with milk replacer after birthed 9 days, and before this, they had been fed with eolostrum for two days and gone through transition period of 6 days. In the experimental period, the calves in control group and test group were separately fed with milk and milk replacer of equal quantity. The results showed that the rate of calf diarrhea in exper- imental group was 25% lower than the control group, and the average weaning weight and daily gain had respectively increased by 4.70kg and 81g, the difference reached a significant level （P〈O.05）. In addi- tion, every calf in test group could save feeding cost of 575 yuan compared with the control group. Therefore, it was feasible to use milk replacer substituting milk to feed calves at early stage.
