Abstract
Milk production records for valley and mountain pastured Braunvieh cows of Tirol region in Austria were collected in the period from 1977 to 1981. Data on 46456 lactation records including 16569 paternal half-sisters representing 1556 sires were used to estimate the genetic and phenotypic variation and covariation of and between 305-day and total yield and percentages milk traits. Heritabilities for yield traits ranged from 0.40 to 0.54 for 305-day laction and from 0.36 to 0.45 for total lactation, while the estimates for fat and protein percentages were 0.30 and 0.40, respectively. Genetic and phenotypic correlations among yield traits and fat and protein percentages were estimated.
