Sažetak
Monitoring showed that more than 70% of the layer and breeder flocks in Europe are positive for Mycoplasma synoviae. It can cause respiratory distress, synovitis and changes on egg shells. However, it is usually manifested as mild infection causing oxidative destruction of the epithelia, thus opening entrance for other, generally opportunistic pathogens, like E. coli and G. anatis. Vaccination of MS using MS-H strain showed excellent results in the protection of layers and breeders, as well as autogenous vaccines against E. coli and G. anatis. In this study we present results of simultaneous application of MS-H and autogenous E. coli + G. anatis vaccine in broiler breeder flocks. In total 8 flocks of 31000 Ross 308 breeder hens were longitudinally monitored. Three flocks were vaccinated twice using commercial live and inactivated vaccines for E.coli, while two flocks were vaccinated using only autogenous E. coli vaccine twice. One flock was vaccinated once using MS1 strain of MS in combination with autogenous E. coli twice. On the other hand, two flocks were vaccinated once using MS-H vaccine at 9 weeks, and twice using autogenous vaccine, in one flock only with E. coli and in the second E. coli + G. anatis vaccine at 9 and 16 weeks of age. Production parameters (egg production, total and weekly mortality) were collected in each flock during production till the 60 weeks of age and analysed statistically. Results showed statistically significant drop in mortality and increase in egg production in the flocks simultaneously vaccinated with MS-H and autogenous vaccines compared to the flocks vaccinated only with commercial vaccines, with average decrease from 19, 37 to 10, 3%. Also, same flocks have had lower mortality compared to flocks vaccinated only with autogenous vaccines, but not significantly, which is 14, 93%. In conclusion, combination of MS-H and autogenous vaccine significantly lowers the mortality in broiler breeder flocks and improves the production.
