Abstract

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 (PP.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.
