Genetic Structure of Quantitative Characters in Pinzgau of Transilvania Breed from Hateg Region

Abstract

Measurements made on 270 cows of Transilvanian Pinzgau breed from Hunedoara county enables us to establish the genetic structure for productive characters as milk production and reproduction. We found the followings. Transilvanian Pinzgau breed from Hateg county has its own genetic structure but similar to the one raised in region of Bucovina, for characters which concur to milk production for these contributing to reproduction efficiency. The average potential of milk production is 305 days and does not overrun 3550 Kg milk with 130 Kg fat (3,8%)but with a good persistence of milk synthesis during normal lactation. Maximum of milk production is manifested in the 7th lactation and the average longevity overruns 9 lactations. Transilvanian Pinzgau is characterized by a remarkable fecundity and natality, with a low rate of embryonic abortion. Genetic handicap for this breed is its productive tardivnness and reproduction (it can enter reproduction without negative morphologic and functional consequences at the age of 21 months when it realizes 68% of the adult mass).
