STUDY REGARDING MAIN PHENOTYPIC TRAITS CARACTERIZATION TO MILK PRODUCTION DIRECTION IN BOVINE BRUNA BREED IN MARAMURES COUNTY

Abstract

In this work paper are presented and done the analysis of the main phenotypic traits values in bovines of Bruna breed, in Maramures county, established basing on data from evidences belonging to Animal Husbandry Amelioration and Reproduction Offices in Maramures county, after data bank of ANARZ and after primary evidences from every selection center. Researches were done on a total live stock of 2632 cows, Bruna breed, bred in Maramures county. Main productive traits were established in dynamic on 6 lactations, having in view milk quantitative and qualitative production during normal and total lactations, but also reproduction index. Researches done regarding main productive traits have led to Bruna breed bovine characterization per total population, in Maramures county. The analysis of milk production index and variability on successive lactations shows us that the population taken in study is characterized by favorable productive traits such as milk quantitative production report as also on qualitative production. Concerning reproduction index researches done in farms from Maramures county localities have put in evidence the fact that average values of reproduction index (age of first parturition, mammary repose, calving interval and service period) certify an adequate state of reproduction function.
