摘要
[目的]肉牛的呼吸道疾病(BVD)多因运输应激而引起的一种顽固性疾病,常因临床治疗效果不佳,饲养成本增加。为降低本病给牧场造成的损失,自2020年3月26日起,针对华润集团开鲁隔离场,牧场购自伊胡塔交易市场的西门塔尔品种架子牛。[方法]使用德国勃林格公司育肥牛到场操作流程方案进行应激处理并跟踪各项数据,与单纯使用勃林格公司驱虫药害获灭做对比评估,通过药物成本、死淘情况、增重指标的对比来评估方案优劣及成本核算分析。[结果]结果显示,(1)同样品种的西门塔尔育肥牛,在采购进入育肥场前后,进行不同应激处理方案,相比较只做害获灭+FMD疫苗处理的牛群,使用专克灵+害获灭+FMD疫苗处理的牛群,平均每头牛的日增重差别可以达到0.3 kg/d,根据目前市场行情条件下,育肥牛销售约32元/kg的价格,在入场30 d内,平均每头牛可以多获得239.6元的更多增重育肥收入;(2)在入场后使用专克灵预防BRD,配合害获灭驱虫,相比较入场后只做驱虫处理,能获得更低的BRD发病率(低28.7%),发病牛更短的治疗天数(少0.5 d),更佳的平均日增重(多300 g),能够带来更好的增重收益;(3)实验组与对照组差别为0.3 kg,即平均日增重差别300 g。[结论]该数据可以直观说明,入场时,是否全群专克灵处理牛群,预防BRD,对于后续日增重的影响,差异极其明显。
[Objective] Respiratory disease(BVD) in beef cattle is a stubborn disease caused by transportation stress, which often leads to poor clinical treatment effect and increased feeding costs. In order to reduce the losses caused by this disease on pasture, since March 26, 2020 for Simmental cattle from Ihuta Trade Market at Kailu Quarantine Farm of China Resources Group. [Method] Stress treatment was carried out using on-site cattle fattening operations flow scheme developed by Boehringer Company of Germany, and various data were tracked and the results were compared and evaluated compared to insect elimination with Boehringer repellent alone. Through the comparison of drug cost, the mortality situation and the weight gain index, the advantages and disadvantages of the program were evaluated and the cost accounting analysis was carried out. [Result] The results showed that:(1) Before and after purchase and entery into the fattening farm, Simmental fattening cattle of the same breed received different stress treatment programs. Compared with cattle treated only with +FMD vaccine, the differences in average daily weight gain of each cow could reach 0.3 kg/d, according to current market conditions, the selling price of fattening cattle was about 32 RMB/kg. Within 30 days after administration, the average cow could get more weight gain and fattening income of 239.6 RMB.(2) After administration of Zhuankeling for BRD prevention, combined with pest elimination and deworming, it was possible to reduce BRD incidence(by 28.7% lower), shorten treatment days(by 0.5 days less) and increase average daily gain(by 300 g more), resulting in greater gain.(3) The difference between the experimental group and the control group was 0.3 kg, i.e. the difference in average daily gain was 300 g. [Conclusion] These data can intuitively explain whether the whole group of Keling could treat cattle and prevent BRD at market entry, and the difference was extremely obvious for subsequent daily gain.
