Effect of Cold Stress on Milk Yield, Milk Composition and Some Behavioral Patterns of Simmental Cows Kept in Open Shed Barns
Öz
The aim of this study was to determine effect of cold stress on milk yield, milk composition and some behavioural patterns of Simmental dairy cattle kept in open shed barns. In the present study, daily milk yield, milk content, somatic cell count (SCC) in milk and some behavioural patterns of Simmental dairy cattle during winter were determined. Besides, wind chill temperature (WCT) was calculated by using wind speed, temperature and relative humidity rate. In the present study, diffence between mean value of wind speed, temperature, relative humidity rate and WCT characteristics were proved as significant (P<0.01) depending on months in winter. Difference between mean value determined in months winter as for milk composition traits such as protein and total dry matter rate, and SCC were proved as significant (P<0.05). It was also confirmed that negative phenotypic correlation exists between milk fat and total dry matter rate, and WCT (P<0.05). There were also significant differences as for rate of incidence of behavioural patterns such as lying and walking during months winter (P<0.05). In conclusion, it was determined that cold stress affects protein and total dry matter rate in milk, SCC and behavior patterns such as lying and walking of Simmental dairy cattle.
