酸化奶对哺乳犊牛日增重、腹泻率、饮奶量和饲养劳动强度的影响

Effect of Acidified Milk on the Production Performance of Calves and the Labor Intensity

本试验主要研究酸化奶对哺乳犊牛日增重、腹泻率、饮奶量和饲喂人员劳动强度的影响。试验包括三个处理组:对照组、甲酸酸化奶组(甲酸组)和固体酸化剂酸化奶组(固酸组)。结果表明:(1)饲喂酸化奶可提高哺乳犊牛日增重,固酸组的日增重高于甲酸组,与传统的饲喂常乳相比日增重提高37%(P<0.05);(2)与传统饲喂方法相比,酸化奶可以减少犊牛的腹泻率,腹泻率降低了85%~92%(P<0.05);(3)对照组、甲酸组和固酸组达到断奶体重的哺乳时间分别为57d、48d、39d,三组累计平均饮奶量为352L、442L和383L;(4)酸化奶可供犊牛自由饮用,可以降低人员的劳动强度(P<0.05)。综合上述结果,饲喂酸化奶可促进犊牛生长、降低犊牛腹泻率及工人的劳动强度。

This study was conducted to evaluate the effect of acidified milk on growth performance, and diarrhea rate of calves and daily labor intensity. Three treatments included the control, formic acidified milk （FAM） and solid acidified milk （SAM）. The results showed that （1） acidified milk improved ADG of calves （P〈0.05）; （2） acidified milk reduced diarrhea rate by 92% （P〈0.05）; （3） acidified milk reduced the labor intensity of workers （P〈0.05）. In conclusion, acidified milk could promote calf growth, reduce diarrhea rate and improve the farm benifits.
