Süt Sığırcılığı İşletmelerinde Sağımcının Verimlilik ve İşletme Gelirine Etkisi

Abstract

Nowadays, milking process in a dairy farm is carried out with the "animal, human and machine" trio closely related to each other. Expected success in milking process is ensured by the animal's accustomedness to the milking machine, the skill and experience of the milkman, and the functional conformity of the milking machine. The aim of this study was to determine the effect of milkman on milk productivity and revenue. As study material, average milk yields obtained from 387 milking of 35 Holstein cows raised in the farm was used. The cows were milked by 6 different milkmen. Linear Mixed Models were used to determine the effect of different milkman and milkman experience on the average milk yields. In addition, the difference in milk yields due to milkman was analyzed in terms of economy. In the study, it was determined that the individual milkman and milkman experience were significant for the average milk yields. Thus, a difference of 2.3 kg was determined between 1 st milkman (the highest average milk yield; 22.6±0.46 kg), and 5 th milkman (the lowest average milk yield; 20.3±0.76 kg), and the difference was statistically significant (P=0.011). This difference in the average milk yield was reflected in 80 liters of additional milk yield per day and 184 ₺ (31.9 $) additional revenue increase achieved in the farm where 35 cows were milked. This difference in income corresponds to the cost of an insured worker. Milkman experience has been split in three categories, the difference between the average milk yield obtained by the least experienced milkman and the average milk yield of the most experienced milkman was found to be statistically significant (P=0.04). This case shows that the experienced milkman income about 156 ₺ (27.03 $) more per day. In conclusion, it was determined that the milkman factor was important for the profitability of the farm in dairy cow. The experienced milkman may earn his own salary with the income increase provided for the farm, and, therefore, economically does not cost extra.
