STUDY REGARDING MAIN PHENOTYPIC TRAITS CARACTERIZATION TO MILK PRODUCTION DIRECTION IN BOVINE BRUNA BREED IN MARAMURES COUNTY
Keywords:
bovine Bruna, phenotypic, milk, MaramuresAbstract
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.
