摘要
Abstract
This study aimed to evaluate the impact of combined immunization strategies on disease prevention and control efficacy as well as economic production benefits in pig farms,to determine the optimal vaccination protocol.The trial was divided into group A(combined immunization group)and group B(control group).In group A,all sows received a single-shot quadrivalent vaccine of"cir-covirus-Haemophilus bivalent vaccine(Porcine circovirus type 2 and Haemophilus parasuis inactivated bivalent vaccine)+Ke Chuan-ning+Wen Kejian"30 days before farrowing,and their piglets were vaccinated with"circovirus-Haemophilus bivalent vaccine+Ke Chuanning+Wen Kejian"at 21-23 days of age.In group B,all sows were vaccinated with vaccine of"Wen Kejian+circovirus-My-coplasma bivalent vaccine"at 35 days and 25 days before farrowing.Production indicators of sows and their piglets after vaccination were statistically analyzed,and serum antibodies against swine fever and circovirus disease were measured at different immunization stages in both groups.The results showed no significant difference in piglet production performance between the combined immuniza-tion group and the control group,though the former slightly outperformed the latter.Additionally,there were no notable differences in circovirus disease antibodies or swine fever antibodies between the two groups of sows and their respective piglets.Given the require-ments of intensive production,the combined immunization mode of"circovirus-Haemophilus bivalent vaccine+Ke Chuanning+Wen Kejian"(one-shot quadrivalent vaccine)is currently the optimal vaccination strategy for pig farms.关键词
