| 摘 要： | 为探究蒸汽压片玉米和膨化大豆对犊牛生长性能和屠宰性能的影响,选用3日龄内吃足初乳的健康荷斯坦公犊牛39头,随机分为3组,每组13头,分别为代乳粉组(Ⅰ组)、50％代乳粉+蒸汽压片玉米及膨化大豆混合精料组(Ⅱ组)和蒸汽压片玉米及膨化大豆混合精料组(Ⅲ组).1～30日龄,3个组均饲喂鲜奶,30日龄后备组逐步替换成试验日粮,150日龄时屠宰,并测定屠宰性能.运用SAS 8.0软件进行数据统计处理.结果表明:31～90 d Ⅰ组犊牛的日增重极显著高于Ⅱ组和Ⅲ组(P＜0.01),但随着犊牛日龄的增大,Ⅱ组和Ⅲ组的日增重与Ⅰ组逐渐接近并最终超过Ⅰ组,150 d试验结束时,Ⅰ、Ⅱ和Ⅲ组犊牛的平均体重分别为230.18、225.10和229.45 kg,组间差异不显著(P＞0.05)；Ⅲ组的各屠宰指标与Ⅰ组均没有显著差异(P＞0.05),而Ⅲ组的宰前活重和眼肌面积有高于Ⅰ组的趋势(P＜0.1)；饲料成本分析表明,Ⅲ组的饲料成本极显著低于Ⅰ组(P＜0.01).蒸汽压片玉米及膨化大豆可以替代代乳粉饲喂断奶后犊牛,并能增大眼肌面积,显著降低生产成本. |
| 关 键 词： | 奶公犊 蒸汽压片玉米 膨化大豆 生长性能 屠宰性能 |
