Monitoring of immune system status in dairy and beef bull sires

Resumo

Research into the immune system status of bull sires is focused on finding the ways to enhance the breeding values of animals and to correct the innate resistance in the organism. The objective of the study was monitoring the immune system status indices and the correlations between them in various bull breeds. It was ascertained that there were more strong correlations between the immunological parameters in the beef bull sires compared with the dairy cattle.
