Investigation of Effects on Fertility and Time of Naturel Mating and Parturition in the Middle Anatolia Merino Ewes to the Ram Effect during the Breeding Season in the Town of Konya Province Karapınar (II)

This study was conducted to investigate the effects on the duration of natural meeting and parturition in the merino ewes to the different application of ram effect during the natural breeding season. On the sixth day of the study; In one of two companies (company I), the rams was removed during six days from the flock of sheep. This application was not made on the other (company II). In other company, this application wasn't done. First enterprise where the rams were removed then again, the rams were joined the flock and second enterprise were mated next 19 and 50 days %90,3 (271/300) and %97 (388/400), respectively. Flocks in the both enterprises were mated with natural mating. Breeding season were completed 39 and 65 days for the first and second sheep enterprise, respectively. When parturition season between enterprises was evaluated, Merino ewes in the first and second enterprises gave birth %87,3 (254/291) and %87,4 (326/373) respectively. Parturition season of the first group was completed in 41days (the first 20 days was more intense) and in the other group lasted for 63 days (the first 29 days was more intense). As the result of this study, the duration of merino ewes exposed to rams (keep 6 days in flock, remove 6 days from flock and get back to the flock) in the breeding season is found to be effective on the time of mate and parturition (P<0.05). In the direction of fertility, there was no difference between practices (P≥0.05).
