Abstract

The course paper presents a comprehensive assessment of swine respiratory diseases in pig farming and studies the peculiarities of pathoanatomical pattern of swine mycoplasmosis. A productive research has been conducted based on the use of “Chiogen” vaccine against swine mycoplasma, suggested by a French enterprise “Seva Sante Animale”. Upon drawing conclusions from research we compared productive rates of fattening livestock: live weight, the duration of fattening, livestock mortality, and the level of mycoplasmal involvement of lungs both after being vaccinated with “Chiogen” and not. During the post-butchering examination at the slaughterhouse 102 lung samples of commercial standard pigs were analysed. The data obtained confirmes that within the experimented group the duration of fattening period was 10 days lower, livestock livability was 3,1 % higher and average daily gains of live weight increased by 60 grams. This positive trend is due to a decrease in the level of mycoplasmal involvement of lungs after vaccination.It has been found that “Chiogen” vaccine reduces pathological lung lesion up to 13 %, apical lobes sealing up to 7 %, and there were no adhesion and scars at all compared to the unvaccinated group. Thus, “Chiogen” vaccine produced by the French company “Seva Sante Animale” reduces pathological lesions with typical pathoanatomical changes, common to M. Hyo. The proposed vaccine generates a complete protection against enzootic pneumonia, respiratory diseases and mixed bacterial and viral infections of livestock, increases daily gain of live weight and adjusts the immune status of the animals.
