The aim of the present study is to investigate the impact of some environmental factors on the descriptive values of milk yield characteristics in Holstein cows. For this purpose, a total of 241 lactations belonging to 62 Holstein cows had been kept as breeders in a private establishment were evaluated for 7 years in terms of milk yield. When the recording system of the establishment was examined, the average values of lactation yield (LY), corrected 305 day milk yield (305-dMY), average daily milk yield (ADMY) and lactation length (LL) were 9356.2±126.1 kg, 8549.2±105.8 kg, 28.0±0.3 kg and 315.0±2.3 days, respectively. The least mean squares (LMS) of LY was calculated as 9324.9 kg. It was found that the effect of the calving season on the LY was statistically significant (P |
