The Effect of Different Environmental Factors on Milk Yield Characteristics of Holstein Fresian Cattle Raised with Different Production Scale on Teke Region of Turkey

This study was intended to determine whether there any difference between the parameters of herd size and milk yield based on hypothesis that dairy cattle enterprises in Teke Region used different production methods depending their size. Total 305-d were increased parallel with farm-scale reached 8968.70 ± 124.56 kg 7632.20 79.67 kg, respectively, farms largest scale 101 heads above (p < 0.001). It further determined decreased significantly summer calving season compared other seasons (Summer: 7897.20 154.48 b, Autumn: 8344.80 169.33 a, Winter: 8054.50 127.22 Spring: 8133.60 159.77 a) 0.01). Heat stress is thought be reason for low seasons. shown small-scale 1–10 cows had longest lactation length (394.90 6.90 days) also a directly proportional significant relationship number Holstein values 5th highest value 6992.00 164.40 kg. In conclusion, positive statistical correlation found parameter.
