Factors affecting daily milk yield, fat and protein percentage, and somatic cell count in primiparous Holstein cows

Popis výsledku v původním jazyce

The objective of this study was to determine effective factors on the variation of daily milk yield (DMY), fat (F%) and protein percentage (P%), and somatic cell count (SCC) in Holstein cows. A total of 278 primiparous cows were examined by four parameters in four calving seasons (CS), three years and six test days (TD) post-calving. While SCC and fat values were affected by CS (P<0.05), no significant difference was found among DMY and P% by CS. Both year and TD were not effective on SCC, but significant differences (P<0.05) were determined among DMY, F% and P% by two factors. Correlation of P% with SCC and F% was estimated to be positive (P<0.01; r=0.168 and r=0.457, respectively), and correlation of DMY with fat and protein was determined as negative (P<0.01; r= -0.363 and r= -0.335, respectively). The study confirmed that multiple milk parameter factors are highly important to obtain more quality and quantity milk from primiparous dairy cows.
