Özet
This study was done to investigate some environmental factors (calving year, calving season and calving age) affecting milk yield traits and milk yield traits of Brown cows raised at the Malya state farm. The least square means of lactation duration, lactation milk yield, 305-day milk yield and dry period were estimated as 312.02 +/- 0.98 days, 5811.28 +/- 26.31kg, 5525.92 +/- 22.35 kg and 76.82 +/- 0.63 days, respectively. Effects of all environmental factors on lactation milk yield (actual milk yield) and 305-day milk yield were found statistically significant (P<0.001). Similarly, effects of calving season, calving year and calving age on lactation duration were found statistically significant (P<0.001-P<0.05). Effects of calving year, and calving age on dry period were statistically significant (P<0.001). According to result in this study, it can be said that Brown cattle are raised successfully at Malya state farm in region under steppe climate conditions of Turkish and yield levels of Brown cows were very good.
