Abstract :The aim of study was to investigate the effect of corpus luteums insert ignore into journalissuearticles values(CL); size that detected before embryo transfer on conception in recipient Holstein cows. The recipient cows utilized had at least one birth and aged 3-8 years old. PGF2α was injected 2 times space 14 days apart to cows and 87 cows which show estrous symptoms were determined as recipient. Fresh embryos were transferred after estrous in 6th-8th days. Ovaries were examined by ultrasound before transfer and CL sizes were measured. A scale of ‘++++’ were set as a result of measurements. Recipient cows were into 3 groups. The first group was named as CL2+ insert ignore into journalissuearticles values(n=25); and consisted of cows with ‘++’ insert ignore into journalissuearticles values(≥15-20 0.05);. As a result, it was concluded that the size of the corpus luteum has no effect on the conception of cows utilized as recipients in embryo transfer.
