Postpartum anöstrüs
süt sığırlarının doğum sonrasında kızgınlık döngüsünün görülmediği dönem olarak
bilinir. Süt sığırlarında postpartum anöstürün uzaması üreme etkinliğini
sınırlayan en temel etmenlerden biridir. Postpartum anöstrüs yetersiz beslenme,
süt verimi ve çeşitli patolojik etmenler (kronik zayıf düşürücü hastalıklar
veya uterus ve ovaryum hastalıkları) gibi pek çok faktörden kaynaklanmaktadır. Anöstrüsün
engellenmesi uygun beslenme, tedavi yöntemleri (hormon muamelesi) ve yeterli
sağlık tedbirlerinin alınmasıyla gerçekleştirilebilir. Anöstrüs’ün nedenini tam
olarak anlayabilmek ve engelleyebilmek için, a) üremeyi etkileyen doğum öncesi
hastalıkların b) ovulasyon ile ilgili genlerin c) metabolik sinyaller ile
nöroendokrin döngü arasındaki önemli bağlantı fonksiyonu gören bazı proteinlerin (leptin),
anöstrüs üzerine olan etkilerinin belirlenmesi gerekmektedir. Bu derlemede
postpartum anöstrüs ile ilgili ovaryum aktiviteleri üzerinde durulmuştur.
