GENETIC PARAMETERS OF MILKING TRAITS AND SCC IN MILK

SNEŽANA TRIVUNOVIĆ, M. PLAVŠIĆ, D. GLAMOČIĆ

Abstract


The aim of work was to determine genetic parameters for number of somatic cells (SCC) in the cow milk. Research took place on the sample of 247 cows of three different breeds. Genetic parameters were estimated by linear mixed model. It is found that heritability for SCC is 0.014 and genetic correlations with milking traits are small negative to small positive. Results show that decrease of SCC can be accomplished, by optimization of environmental factors, and selection for this characteristic must be done by sophisticated mathematic-statistical methods.
