摘要
作者主要对3种延边黄牛妊娠母牛优化日粮进行了研究。选择16头离预产期3个月的延边黄牛妊娠母牛,随机分为试验1、2、3组和对照组,每组4头,试验组分别饲喂3种不同营养水平的优化日粮。试验结果表明:饲喂3种不同日粮均提高了犊牛的初生重和日增重,其中试验1组犊牛初生重最高,与对照组差异显著(P<0.05);试验组干物质采食量极显著高于对照组(P<0.01),且日粮中DM、EE、CP和NFC的表观消化率提高;血液指标的测定结果表明,试验组的各项指标均高于对照组,但在正常范围之内。本试验研究结果显示,1号精料饲喂效果好于2号和3号,最优化日粮为1号日粮。
This paper was to determine three optimized diets for Yanbian yellow cattle pregnant cows. Sixteen Yanbian yellow cattle pregnant cows were chosen, their expected date of childbirth was 3 months to the calves＇ birth. They were divided into 4 groups and there were four cows in each group. The cows in experiment group 1, 2, 3 were fed optimized diet 1, 2, 3, respectively. The results were as follows, the calves＇ birth weight and daily gain improved because the cows were fed the optimized diets. The calves＇ birth weight in experiment group 1 was significantly higher than control group （P〈0.05）; the DMI of the experiment groups were extremely higher than control group （P〈0.01）; the apparent digestibility of DM, EE, CP and NFC in the experiment groups increased. Blood indexes of the experiment groups were all higher than control group, but they were all in the normal state. To sum up, optimized diet 1 was considered to be the optimization diet.
