Current Approaches In Control Of Reproduction On The Sheep

The sheep, domesticated in the Neolithic Age (7-6 BC), has been cultivated daily for the production of wool, meat and milk since the ancient times. In Turkey, almost in every region of the various sheep breeds (Merino, Akkaraman, Morkaraman, Da？l？？, K？v？rc？k, Awassi, Sak？z, ？mroz, Tuj, Hem？in, Herik) are cultivated for production. While there is an increase in the number of sheep in the world, in 1980 the number of sheep was 46 million in our country, but today this number has decreased to 31 million. For more efficient production, modern farming should be targeted by utilizing technology. For this purpose, various methods are used to obtain good yield without increasing the cost of sheep breeding and to raise the reproductive performance of the animals to a higher level. In addition to technological innovations, the production of sheep can be controlled using natural methods and various hormones. Thus, increases in fertility can become possible. These methods are mainly; since sheep have a photoperiodic cycle, light applications and imitation of the hormones in the normal cycle (Progestagen, PMSG, GnRH, PGF2α) are involved. The purpose of this review is to explain appropriate procedures according to breeds, giving information about the applications carried out to control the breeder during sheep shee
