中文摘要:

      [目的]为研究发酵中药渣对犊牛生长发育、健康状况的影响。[方法]在宁夏固原市肉牛良种繁育示范园随机选取150头犊牛作为试验牛群,采用配对试验设计,试验分为对照组和发酵中药渣组。[结果]日粮中添加发酵中药渣,犊牛采食量增加0.09 kg,日增重增加0.09 kg,料重比(F/G)减少0.06 kg；体重多增加5.2 kg,提高4.4% ,体高、胸围、体斜长分别增长 4.2 cm、5.6 cm、4.4cm,分别提高了4.5%、5.1%、4.1%；试验组滨州筛第 1,2 层筛上物比例下降,说明犊牛消化能力增加,饲料消化率提高；血液总蛋白和白蛋白含量均显著高于对照组；谷丙转氨酶含量显著低于对照组；谷胱甘肽、过氧化物歧化酶、免疫球蛋白G含量显著高于对照组。[结论]在犊牛日粮中添加发酵中药渣可增加犊牛的采食量和日增重,提高饲料报酬,提高血清总蛋白,降低谷丙转氨酶水平,增加过氧化物歧化酶活性,提高犊牛免疫力。

英文摘要:

      [Objective] To study the effect of fermented Chinese medicine residue on growth and health of calves. [Methods] 150 calves were randomly selected as the experimental group in Ningxia Guyuan beef cattle breeding demonstration park. The experiment was divided into control group and Fermented Chinese medicine residue group. [Results] Adding fermented traditional Chinese medicine dregs to the diet, calf feed intake increased by 0.09 kg, daily gain increased by 0.09 kg, and feed/weight ratio decreased by 0.06 kg；The body weight increased by 5.2 kg, increased by 4.4%, and the body height, chest circumference and oblique length increased by 4.2 cm, 5.6 cm and 4.4 cm, increased by 4.5%, 5.1% and 4.1% respectively. The ratio of oversize in the first and second layers of the experimental group decreased, which indicated that the digestibility of calves increase and the feed digestibility increase. The contents of total protein and albumin in blood were significantly higher than those in control group. The content of alanine aminotransferase was significantly lower than that of control group. The contents of glutathione, superoxide dismutase and immunoglobulin G were significantly higher than those of the control group. [Conclusion] Adding fermented traditional Chinese medicine dregs to calf diet can increase calf feed intake and daily gain, improve feed reward, increase serum total protein and reduce alanine aminotransferase level. Adding fermented Chinese medicine dregs can increase the activity of superoxide dismutase in calf serum and improve calf immunity.
