摘要: 本研究从动物福利的角度出发,探索通风喷淋对肉牛增重、免疫功能和内分泌的影响。选择体重、月龄相近的健康荷斯坦公犊牛28头,随机分为两组,试验组进行通风喷淋,另一组为对照组,每组两个重复组,每个重复7头牛,进行为期28 d的饲养试验。结果表明,通风喷淋可明显改善畜舍环境,并使采食量显著提高(P<0.05),日增重略有提高,料重比略有降低;极显著降低血清促肾上腺皮质素(ACTH)及皮质醇(CORT)含量(P<0.01),且使血清生长激素(GH)、免疫球蛋白G(IgG)、免疫球蛋白M(IgM)含量在试验不同阶段都显著升高(P<0.05)。可见,加强通风喷淋可提高肉牛增重和免疫功能,改善动物福利状况。

Abstract: The present study was conducted to study the effects of ventilating and spraying on the gain performance, immune function and incretion of beef cattle in north China from the point of animal welfare. Twenty-eight Holstein bull calves with similar body weight and age were randomly divided into two groups with two reduplicates in each group. One was the experimental group with the device of fan and water sprayer, and the other was the control group.The experiment lasted for 28 d. The results showed that the environmental state in animal house was significantly improved by ventilating and spraying, and feed intake was significantly increased (P<0.05). In addition, the concentrations of ACTH and CORT in serum were significantly reduced (P<0.01), and the concentrations of GH, IgG and IgM in serum were significantly increased compared with the contral group in every test stage. Overall, gain performance and immune function were ensured and animal welfare was improved by ventilating and spraying.

Key words: beef cattle; ventilating; spraying; gain; immunity
