Özet:

 Calving efficiency, an important target in cattle breeding, has been negatively affected by some environmental factors. Therefore, calving difficulty creates negative economic consequences. In this study, it was aimed to investigate the relationship between the first calving difficulty in Holstein Friesian HF cows in terms of management and origin factors. The material of the research consists of 1475 calving difficulty records from 5 different enterprises engaged in HF breeding, located in the Central Anatolia Region of Türkiye, covering the years from 2013 to 2019. The scoring system used to determine calving difficulty: normal without intervention NB, normal with intervention NBI, difficultintervention with equipment DB, and abnormal birth AB. In the calving difficulty analysis, the management factor is classified as 1-2-3-4-5 and the origin of the cow is classified as 1 foreign origin and 2 native origin. No findings were observed for NBI scores. Total NB, DB, and AB scores were 1250 84.74, 192 13.01, and 33 2.25, respectively. Chi-square test was performed to test the differences among farms. Among the enterprises, the highest NB rate was observed in the 5th enterprise with 90.07, the minimum DB rate was observed in the 5th enterprise with 8.45, and the AB rate was at least 0.66 in the 1st enterprise. The difference between farms was significant for calving difficulty P0.01. Cow origin was not significant on the calving difficulty score. While the NB rates in foreign-origin and native-origin animals were 86.36 and 84.64, and the DB rates were 13.64 and 12.97, respectively. The AB score was not seen in foreign-originated cows, but the AB rate was 2.39 in native-origin cows. To reduce the calving difficulties in enterprises, it may be recommended to determine management procedures appropriate to the region and enterprise and to determine semen suitable for the breed, age, and size of the heifer.
