【摘要】：本试验旨在研究奶粉增强剂对饲喂奶粉犊牛生长性能及健康状况的影响。选择体重相近的新生犊牛28头,随机分成2个处理,每个处理14头,公、母各半。对照组饲喂奶粉,试验组饲喂90%奶粉+10%奶粉增强剂。试验期为10周。结果表明:在6~8周龄阶段试验组母犊平均日增重显著高于对照组(P0.05),试验期间各处理对犊牛干物质采食量和饲料转化效率无显著性影响(P0.05);在0~10周龄阶段试验组母犊体高变化率显著高于对照组(P0.05),同期试验组公犊的体高变化率高于对照组,但差异不显著(P0.05);试验组公犊、母犊10周龄的体躯指数均显著高于对照组(P0.05),各处理组的体长指数差异不显著(P0.05);试验期间试验组与对照组犊牛腹泻率比为1:2.25,发热率比为1:4.5。综上可知,在奶粉中添加奶粉增强剂可提高犊牛日增重,改善犊牛体尺,降低犊牛哺乳期的腹泻和发热情况。
[Abstract]:The purpose of this experiment was to study the effect of milk powder intensifier on growth performance and health status of milk powder calves. 28 newborn calves of similar body weight were randomly divided into 2 treatments, 14 in each treatment, male and half in female. The control group was fed with milk powder. The test group was fed with 90% milk powder 10% milk powder enhancer for 10 weeks. The results showed that the average daily gain of calves in the test group was significantly higher than that in the control group at the age of 6 ~ 8 weeks, and the dry matter intake and feed intake of calves were significantly higher than that of the control group during the experiment. The change rate of body height of female calves in the test group was significantly higher than that of the control group at the age of 10 weeks, and the change rate of the body height in the experimental group was higher than that in the control group at the same time. However, there was no significant difference in body length index between the test group and the control group (P 0.05), the body index of the female calf in the test group was significantly higher than that of the control group (P 0.05), and the body length index of each treatment group was not significantly different from that of the control group (P 0.05). During the trial period, the diarrhea rate and fever ratio of the calves in the test group and the control group were 1: 2.25 and 1: 4.5 respectively. Adding milk powder to milk powder can increase the daily gain of calves, improve the body size of calves, and reduce the diarrhea and fever of calves during lactation.
