Although, various and a number of studies have been made with respect to oestrus synchronization, it is seen that hormone administration is still not widely used in sheep production today. Conducting the research in producers’ flocks has enabled the use of hormones for oestrus synchronization to be transferred to practice. With synchronization practices and by arranging births according to the most convenient time for producers, maximum profitability can be attained. Thus, studies to be made on exogenous hormone use under producers’ conditions should be accelerated and care and feeding opportunities should be improved in order to attain more success in practices.
