Neolitik Çağ’da (M.Ö. 7-6)  evcilleştirilmiş olan koyun, eski insanlardan
beri günümüze kadar yün, et ve süt üretimi amacıyla yetiştirilmektedir.
Türkiye’de de neredeyse her bölgede çeşitli koyun ırklarının (Merinos, Akkaraman,
Morkaraman, Dağlıç, Kıvırcık, İvesi, Sakız, İmroz, Tuj, Hemşin, Herik)
yetiştiriciliği yapılmaktadır. Dünyada koyun sayısında bir artış gözlenirken
ülkemizde 1980’de koyun varlığı 46 milyon iken bugün bu sayının 31 milyona
gerilediği görülmektedir. Daha verimli bir üretim için teknolojiden
faydalanarak modern yetiştiricilik hedeflenmelidir. Bu amaçla koyun
yetiştiriciliğinde masraflar artırmadan iyi verim elde etmek ve hayvanların
üreme performanslarını üst seviyeye çıkarmak için çeşitli yöntemler
kullanılmaktadır. Teknolojik yeniliklere ilaveten doğal yöntemler ve çeşitli
hormonlar kullanılarak koyunların üretimi denetim altına alınabilmektedir.
Böylece dölverimde artışlar mümkün hale gelebilmektedir. Bu yöntemler başlıca;
koyunların fotoperiyodik bir siklus düzeni olduğundan, ışık uygulamaları ve
normal siklus içerisindeki hormonların (Progestagenler, PMSG, GnRH, PGF2α)
taklidi yer alır. Bu seminerin amacı koyunlarda üremenin denetlenmesi amacıyla
yapılan uygulamalar hakkında bilgiler vererek turlere göre uygun prosedürleri
açıklamaktır.

Current Approaches In Control Of Reproduction On The Sheep

Öz

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,
Dağlıç, Kıvırcık, Awassi, Sakız, İmroz, Tuj, Hemşin, 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 sheep
