ESTIMATION OF GENETIC ADDITIVE VARIANCE OF MILK PRODUCTION IN DAIRY ROMANIAN BLACK SPOTTED BREED FROM PESTRESTI-ALBA FARM

GH. NISTOR, ELEONORA NISTOR, V. BAMPIDIS

Abstract


The objective of this study was to estimate the heritability of milk, milk fat and milk protein productions in Romanian Black Spotted breed cattle from SC Dorin&Sanda SRL private farm, Petresti-Alba. A total of 101 lactations cows were used to estimate heritability variabilites among milk yield (kilograms), fat and protein content. The data were collected over a period of two years (2006-2007). Heritabilities were 0.31, 0.68 and 0.73 for milk yield, fat content and protein content, respectively. Heritabilities were among the limits found in the literature. Data can be use as a guide for selection to improve milk yield while maintaining fat and protein contents.
