The effect of the farm size on milk traits of cows
2011
Objective of this study was to analyze the effect of the dairy farm on milk
traits of cows in Vojvodina. The research was carried out on small farms with
10 to 20 cows, medium farms with 20 to 50 cows, and large farms with over 50
dairy cows. The study included registered animals of Simmental (SM) and
Holstein-Friesian breed (HF; including Red Holstein) in the first lactation
for traits of milk yield and yield and content of milk fat. Total of 1323
first lactations were analyzed. The average milk yield (both breeds) in the
first lactation of 305 days was 6295 kg of milk with 234,3 kg of milk fat and
average milk fat content of 3,74%. Milk performance of cows varied
significantly (CV=22,9% and SD=1447,8), as well as milk fat yield (CV=21,6%
and SD=50,8). Large farms produced in average 6534 kg of milk, medium farms
6347kg and small farms 4717kg. Size of the farm exhibited significantly high
effect on all observed traits, and the tendency was that farms with higher
number of animals realize also higher average of production. Farm management
and various breeding-zootechnical conditions present on farms had significant
effect on milk performance of cows.
