| description | In the pig farm with signs of a respiratory disease complex and laboratory confirmed enzootic pneumonia, the prophylactic efficacy of the combination vaccine (M. hyo+PCV2), a single injection administered intramuscularly 21 days after birth, at a dose of 2 ml was tested. The clinical condition, pathological changes in the lungs and some epidemiological and economic results were reported. It was found that vaccinated pigs are in a better clinical condition in comparison with the control group. Morbidity in the rearing period was reduced from 16.3% in the control group to 6.0% in vaccinated pigs, and in the fattening period, respectively, from 30.6% in the control group to 10.0% in the vaccinated group. Pathological features in the lung characteristic for the enzootic pneumonia in the vaccinated pigs were reduced from 25.5%±7.24 to 4.0%±2.44, and PCVI - from 13.0%±4.66 to 0%. Vaccination of pigs has been received and a higher average daily gain in groups for rearing (0.624 kg) and for fattening (0.723 kg) was recorded. |
