Control of Coccidiosis in Calves by Vaccination
The immunizing effect of inactivated sporulated oocyst and inactivated sonicated vaccines against bovine coccidiosis was observed in calves. Indirect haemagglutination (IHA) test was developed for detecting antibodies to coccidian. Serum antibody levels in calves were measured against soluble oocyst (sporulated) antigen. IHA antibody titer was significantly higher (P<0.05) in calves vaccinated ...

متن کاملDemodicosis in two Holstein young calves

Demodectic mange in cattle is known to be usually a...
