Economic Losses Associated with Fertility in Dairy Farms

Öz

This investigation aimed to determine the effects of some environmental factors on fertility traits and economic losses caused by deviations from the ideal levels of these parameters.
The records of 126 Holstein and Simmental first-calf heifers from three dairy cattle enterprises in Afyonkarahisar during the period 2010 – 2016 were examined. The technique ANOVA were used to detect the effects of different environmental factors and fertility related economic losses were calculated.
The ages at first calving and services per conceptions were determined as 872.6 - 949.2 and 1.74 - 1.47 days in Holsteins and Simmentals. The effect of the year on services per conception was significant (p<0.05). Calving intervals were found to be 430.7 to 404.6 days, respectively. The average economic losses of farms caused by deviations from the ideal levels in age at first calving and first calving interval calculated in terms of calf losses (head) were in the ranges of 15.56 – 24.55 and 3.41 – 8.73 heads. These facts suggested that the deviations from the ideal levels in these traits could be unnoticed or ignored by the enterprise managers and reach to economically remarkable levels. The need for every farm operation must conduct its own economic analysis was unveiled consequently.
