【摘要】：为了提高企业的生产效益,找出最适合本场生产的联合免疫模式,为本场免疫方案的制定提供数据依据,也为本企业其它场的免疫方案制定提供参考,而不是仅凭简单的感官认识去制定,笔者通过调查海南省圆环病毒疫苗和蓝耳病疫苗的使用情况,进行了规模猪场圆环、蓝耳疫苗联合免疫效果研究及推广。试验按六种免疫方案进行,具体试验分组如下：试验Ⅰ组：广东永顺的圆环病毒疫苗14日龄注射+勃林格蓝耳病疫苗21日龄注射,剂量均为1头份；试验Ⅱ组：海利圆环病毒疫苗14日龄注射+勃林格蓝耳病疫苗21日龄注射,剂量均为1头份;试验Ⅲ组：勃林格圆环病毒疫苗14日龄注射+勃林格蓝耳病疫苗21日龄注射,剂量均为1头份；试验Ⅳ组：勃林格圆环病毒疫苗14日龄注射+勃林格蓝耳病疫苗21日龄注射,剂量调整,圆环0.6头份,蓝耳1头份；试验V组：海利圆环病毒疫苗7日龄注射+勃林格蓝耳病疫苗14日龄注射,剂量均为1头份；试验Ⅵ组：海利圆环病毒疫苗7日龄注射+海利蓝耳病疫苗14日龄注射,剂量均为1头份。最后按猪群健康正品率、料肉比、日增重等几个重要生产指标进行分析,筛选最佳联合免疫模式,并推广检验之。从规模猪场圆环、蓝耳疫苗联合免疫方案优化试验以及联合免疫优化结果的推广应用效果来看,规模猪场在对猪圆环病毒病和蓝耳病进行免疫预防时,采用如下免疫方式可取得比较理想的成果。1.对于商品猪场而言,最合适的免疫方式为“上海海利圆环病毒疫苗7日龄注射+勃林格蓝耳病疫苗14日龄注射,剂量均为1头份”。不仅生长猪的各项生产性能表现良好,且能减缓生产成本的压力。2.对于种猪场而言,最合适的免疫方式为“勃林格圆环病毒疫苗14日龄注射+勃林格蓝耳病疫苗21日龄注射,剂量均为1头份”。这种免疫方式,更能保证种猪的品质,使种猪处于优良的健康状态。3.猪场蓝耳病的免疫防御,蓝耳病疫苗不能随意更换,否则,可能会造成蓝耳病的不稳定,从而使得动物机体免疫能力下降,容易继发感染其它疾病。4.从猪圆环病毒病的免疫时间来看,国产猪圆环病毒疫苗早打比较合适,比如上海海利圆环病毒疫苗,无论是保育阶段还是育肥阶段,7日龄免疫最终的结果就比14日龄免疫的效果要好。
[Abstract]:In order to improve the production efficiency of the enterprise, find out the most suitable joint immunization model for the production of the field, and provide the data basis for the formulation of the immunization plan of the field, and also provide a reference for the formulation of the immunization plan of the other fields of the enterprise. Instead of just based on the simple sensory understanding, the author investigated the use of circovirus vaccine and blue ear disease vaccine in Hainan Province, and carried out the research and promotion of the combined immunization effect of large-scale pig ring and blue ear vaccine. The experiment was carried out according to six immunization schemes, and the specific test was divided into the following groups: test group I: 14 days old injection of Bolinger's blue ear disease vaccine in Yongshun, Guangdong Province, the dose of which was 1 dose of Buringer blue ear disease vaccine at the age of 21 days; Group II: Haili circovirus vaccine was injected with Buringer blue ear disease vaccine at the age of 14 days at the age of 21 days at a dose of 1 dose. Group III: Boehringer circovirus vaccine was injected at the age of 14 days at the age of 21 days with a dose of 1 dose. Group IV: Boehringer circovirus vaccine was injected 14 days old with Buringer blue ear disease vaccine at 21 days of age. The dose was adjusted. 0.6 pieces of ring and 1 part of blue ear were injected with Bling circovirus vaccine at 14 days of age. Group V: Haili circovirus vaccine was injected with Buringer blue ear disease vaccine at 7 days of age at 14 days of age, and the dose was 1 dose. Group VI: Haili circovirus vaccine was injected at the age of 7 days at the age of 14 days with a dose of 1 dose. Finally, according to several important production indexes, such as healthy product rate, feed to meat ratio, daily gain and so on, the best combined immunization model was selected and tested. From the optimization test of the combined immunization scheme of the large-scale pig farm ring, blue ear vaccine and the results of the combined immunization optimization, it can be seen that the large-scale pig farm is immunized against swine circovirus disease and blue ear disease. The ideal results can be achieved by using the following immunization methods. For commercial pig farms, the most suitable immunization method was "Shanghai Haili circovirus vaccine 7 days old, 14 days old injection of Buringer blue ear disease vaccine, the dose is 1 dose." Not only the performance of growing pigs is good, but also the pressure of production cost can be reduced. 2. For pig farms, the most suitable immunization method was "Boehringer circovirus vaccine was injected at the age of 14 days at the age of 21 days, and the dose was 1 dose." This immune method can better ensure the quality of breeding pigs and make breeding pigs in good health. 3. The immune defense of blue ear disease in pig farm, blue ear disease vaccine can not be replaced at will, otherwise, it may cause the instability of blue ear disease, thus making the immune ability of animal body decline, easy to secondary infection of other diseases. 4. From the point of view of the immunization time of swine circovirus disease, the domestic swine circovirus vaccine is more suitable for early treatment, such as Shanghai Haili circovirus vaccine, whether in the conservation stage or in the fattening stage. The final result of 7-day-old immunization was better than that of 14-day-old immunization.
