Researches were carried out on 3186 lactations obtained from Romanian Spotted cows raised in farms from Bihor County that were enrolled in official performance control scheme. According to the number of milking cows (farm size), farms were divided into th... see more

The aim of this paper was to study the breeding values and genetic parameters estimation methodology applied on Teleorman Black Head Sheep breed genetic improvement programs. Throughout study were estimated heritability using test-day milk yield and the g... see more

The aim of this study was to estimate the genetic parameters and breeding values for body weight and linear body measurements namely body length, heart girth, height at withers, hip height and tail length of cattle. The number of animals used for the stud... see more

Genotype by environment interaction (G×E) is a potential source of reduced efficiency in genetic improvement programs in livestock. The objective of the current work consisted of checking the existence of G×E interaction in carcass traits and in intramusc... see more
