Abstract


The aim of the study was to investigate the phenotypic parameters of the milk production and the influence of some environment factors in 93 Romanian Spotted primiparous cows from the Research and Development Station for Bovine Arad. The studied parameters were total milk yield per lactation, milk fat and milk protein yield. The average milk production in year 2010 was 6335.1 kg milk with 4.04% fat, 255.6 kg fat and 3.209% protein, 203.6 kg protein. In year 2011, the recorded production was 5756.7 kg milk with 3.94% fat, 227.2 kg fat and 3.202% protein, 184.6 kg protein. A reduction of production from 2010 to 2011 was observed, probably caused by a worse agricultural year and less feed production. After statistical analysis of data distinct significant differences were obtained for milk yield and protein yield, and a very significant difference for protein yield. Differences for fat and protein percentage were not significant from one year to another due to a ration structuring strategy.
