摘要
为探索散栏式与栓系式饲养方式对肉牛增重性能的影响,选择体重相近(330 kg左右)、月龄相同(12月龄)、未去势、健康无病的50头西门塔尔公牛分为2组,每组25头。散栏式饲养为试验组,栓系式饲养为对照组。预试期30 d,正试期120 d,分别于2012年10月、11月、12月,2013年1月和2月进行体重和部分血清生化指标的测定。结果表明:散栏饲养全期西门塔尔牛平均日增重1 268.37 g,显著高于栓系饲养的969.76 g,提高30.79%(P<0.05)。第3个月试验组血清总蛋白(TP)含量极显著高于对照组(P<0.01),第5个月试验组TP含量显著高于对照组(P<0.05);第4个月试验组血清尿素氮(BUN)含量显著高于对照组(P<0.05),而在第5个月极显著高于对照组(P<0.01);两组血清中白蛋白(ALB)和球蛋白(GLB)含量在第1、第2和第5个月组间差异均不显著(P>0.05),在第3和第4个月试验组ALB和GLB含量均显著高于对照组(P<0.05);在第4个月试验组白/球(A/G)含量显著高于对照组(P<0.05);试验组血糖(GLU)含量在第3个月极显著高于对照组(P<0.01),第5个月显著高于对照组(P<0.05)。表明散栏饲养方式比栓系方式更适合于提高西门塔尔牛的生产性能。
The research aims to explore the influence of two different feeding modes（casual bar and tether）on performance of bull production. 50 Simmental bulls with healthy, not castrated, similar weight（330 kg）and age（12 months old）were selected and divided into two groups of 25 bulls each. The first group bulls were casually barred as experimental group,and the second group bulls were tethered as controll group. The period of experiment was 150 d from October 2012 to February 2013. The body weight and size were measured,and the blood samples were taked 5 times in one month intervals. The results showed that：in the two feeding ways,the casual bar group feeding could significantly improve the ADG of Simmental bulls（P〈0.05）,at the level of1 268.37 g,significantly higher than that in tether group（969.76 g）,increased by 30.79%（P〈0.05）;In third month,TP content of the test group was significantly higher than that in the control group（P〈0.01）;in fifth month,the TP content of test group was higher than that of the control group（P〈0.05）;In fourth month the BUN content of test group was higher than that of the control group（P〈0.05）,and in fifth month,the BUN conten of the test group was significantly higher than that of the control group（P〈0.01）;The ALB and GLB contents in the first,second and fifth month in the two models had no significant difference（P〈0.05）,but in third and fourth month,the ALB and GLB content of test group ware higher than that of the control group（P〈0.05）;in fourth month,the A/G of test group was higher than that of the control group（P〈0.05）;in third month,the GLU content of test group significantly higher than that of the control group（P〈0.01）;in fifth month,the GLU content of test group was higher than that of the control group（P〈0.05）.Compared with the tether mode,casual bar mode is more suitable for improving the production performance of Simmental bulls.
