Comparative Study of Gammaglobulin Preparations for Gastroenteritis Prophylaxis in Newborn Calves

摘要

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 11-10 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 incidencein calves 3.3 (t>0.001) and 1.4 times (t>0.05), compared to intramuscular application.
