Comparative studies of gammaglobulin preparations for gastroenteritis prophylaxis in newborn calves were performed. The trial comprised 53 newborn calves. Animals were divided into 5 groups as follows: Group I - 10 calves, injected intramuscularly immediately after calving with 20 ml normal bovine gammaglobulin; Group II - 10 calves, treated per os before the first colostrum intake with 50 ml bovine gammaglobulin; Group III - 13 calves, injected intramuscularly immediately after birth with 20 ml gammafer; Group IV - 10 calves, treated per os immediately after birth with 30 ml gentaglobin-bovis; Group V - 10 calves, control animals - untreated.
The calves were monitored for 14 days for gastroenteritis incidence, severity, disease duration and mortality.
It was found that per os application of gentaglobin-bovis and gammaglobulin had the best preventive effect, reducing gastroenteritis incidence in calves 3.3 (t>0.001) and 1.4 times (t>0.05), compared to intramuscular application.
