KEÇİ YETİŞTİRİCİLİĞİNDE TEKE ETKİSİNDEN YARARLANMA

Küçükbaş hayvanlar mevsime bağlı poliöstrik hayvanlar olup sadece belirli dönemlerde çiftleşme eğilimindedirler. Koyun ve keçilerde özellikle doğum dönemlerinde işletme işgücü oldukça fazladır ve bu süre yaklaşık çiftleşme mevsimi süresi kadardır. İşte bu sürenin kısaltılarak işletme işgücünü daha dengeli olmasını sağlayabilmenin farklı yöntemleri vardır. Bu yöntemlerden biri de teke etkisinden yararlanmaktır. Bu yöntem ile keçilerin kızgınlık ve yumurtlama işlemlerinin arzu edilen zaman içerisinde oluşumuna imkân sağlamaktır. Bu derleme ile doğal yöntemlerle herhangi bir ücret ödemeksizin teke etkisinden yararlanılarak keçilerin kızgınlık ve yumurtlamalarının toplulaştırılması ile diğer kullanılan yöntemler hakkında bilgilendirmek amaçlanmıştır

UTILIZATION FROM BUCK EFFECT IN GOAT BREEDING

Small ruminants are seasonal poly estrous animals and tend to mate only at certain times. In sheep and goats, the workforce is especially high during the period of pregnancy and this period is about the duration of the mating season. There are different ways of shortening this workforce and making the workforce more balanced. One of these methods is to utilize the effect of the buck. With this method goats’ estrous and to allow the ovulation process to occur within the desired time.With this review, it is aimed to inform about the gathering of the estrous and ovulation of the goats and other used methods by taking advantage of the buck effect without paying anything with natural methods
