Özet
Milk and fertility are two criteria that directly affect the profitability of enterprises in dairy farming. Fertility, which is tried to be measured using different criteria, can be defined as the ability of female cattle to get pregnant on time and give birth to healthy calves until later ages. The expected from female cattle is to become pregnant on time and to maintain the ability to give birth to healthy calves as long as they remain in the herd. the number of inseminations per pregnancy is indirectly related to the first of the fertility criteria of females, the age of use in breeding, while the service period is a criterion that directly affects the calving interval and calving year. The aim of the study was to determine the information and economic losses caused by the deviations from the standard values in the Number of Inseminations Per Conception (NIPC) in our country's dairy cattle. The fertility records (NIPC) of 20662 Holstein Dairy cattle (39938) between 2013-2019 belonging to Tekirdag Province CBA constituted the material of the research. When we consider the effect of calving years; It is seen that the years that created the difference have the lowest average of 2014 (1.76 +/- 0.022), and the highest average (1.95 +/- 0.020) stems from the 2015 data. (p<0.01). When we examine the effects of seasons on NIPC; it was seen that the difference was caused by winter (1.81 +/- 0.015) and autumn (1.94 +/- 0.016) seasons (p<0.01). When we evaluate the lactation order, it is seen that the effects of the 1st, 2 nd and 3 rd lactation lines on NIPC are significant (p<0.01). When we evaluated the results in our study, the NIPC average was calculated as 1.87 +/- 0.01. A total of 39938 inseminations were made between 2013-2019. The amount of financial loss corresponding to the failure rate was 10.147.200 TL. Although our results are close to the ideal value, the amount of loss in NIPC in terms of cost is too large to be ignored.
