Abstract

Tuberculosis in cattle has been recorded in some populations of West Siberia for many years. TB average morbidity constituted 20.8% in the researched population. Tuberculosis frequency in families and bulls' offspring’s ranged from 0-6.36% to 9.1- 51.7%, respectively. The coefficients of tuberculosis resistance heritability were 0.06-0.08. Tuberculosis concordance constituted 60.0%. The hypothesis of polygenic inheritance of relative resistance to tuberculosis is proposed.
