Study On Effection Of Porcine Circovirus Vaccineand Porcine Reproductive And Respiratory Syndrome Vaccine Combined Immunizationin Intensive Pig Farm

In order to improve the production efficiency of enterprises, and find out the most suitable for local production of joint immune model, to provide data basis for the establishment of this immunization programs, and also for the company of other immune scheme formulated to provide a reference, not only know to make simple sense, the author through the investigation of hainan province PCVD (Porcine Circovirus Diseases) vaccine and the usage of PRRS (Porcine reproductive and respiratory syndrome) vaccine, the size of an rings, PRRS vaccine joint immune effect research and extension.Test according to six immunization programs, specific test group is as follows:Test ? groups:guangdong yongshun PCDV vaccine injection 14 age and Boehringer-Ingelheim injection PRRS vaccine to 21 age dose 1 ml;Test ? groups:hile-bio PCVD vaccine injection 14 age and Boehringer-Ingelheim injection PRRS vaccine to 21 age dose 1 ml;Test ? groups:Boehringer-Ingelheim PCVD vaccine injection 14 age and Boehringer-Ingelheim injection PRRS vaccine to 21 age dose 1 ml;Test ? groups: Boehringer-Ingelheim PCVD vaccine injection 14 age and Boehringer-Ingelheim injection PRRS vaccine to 21 age dose adjustment PCVD vaccine 0.6 ml with 1 ml of PRRS;Test V groups:hile-bio PCVD vaccine injection 7 age and Boehringer-Ingelheim injection PRRS disease vaccine 14 age dose 1 ml;Test ? groups:hile-bio PCVD vaccine 7 days with hile-bio PRRS disease vaccine injection pig of age 14 dose 1 ml.Finally according to the herd of swine health functions daily gain, feed conversion ratio, several important production index is analyzed, such as screening the best joint immune model, and promote the inspection.From scale pig farms PCVD and PRRS vaccine combined immune optimization test and combined immune optimization results, the popularization and application effect of scale pig farms immune prevention of PCVD and PRRS, using the following immunization can be achieved ideal results.1. For commodity pig farms, the most appropriate way of immune to "Shanghai Haili wreath virus vaccine injection 7 age Boehringer-Ingelheim injection, PRRS vaccine 14 age dose 1 ml".Not only all of growing pig production performance is good, and can reduce pressure on the cost of production.2. As for breeding pig farm, the most appropriate way of immune to " Boehringer-Ingelheim PCVD vaccine injection 14 age and Boehringer-Ingelheim injection PRRS vaccine to 21 age dose 1 ml ".This way of immune can guarantee the quality of swine and breeding pigs in good health.3. The pig immune defense of PRRS, so that PRRS vaccine can't change, otherwise, may cause instability of PRRS disease, so as to descend the animal immune ability and easy to secondary infection of other diseases.4. From the point of the immune time of porcine PCVD. PCVD vaccine of domestic in early injection more appropriate, such as hile-bio PCVD vaccine, both nursery phase and fattening stage, the age of 7 immune to the final result is better than 14 days of age the immune effect.
