Özet
Bu çalışmanın amacı, laktasyondaki Simental ineklerde follikül aspirasyonu (FA) zamanında tek bir ultrason muayenesi ile saptanan dominant follikül (DF) varlığı veya yokluğunun süperstimülatör ve süperovulatör cevaplar ve embriyo üretimi üzerindeki etkilerinin değerlendirilmesiydi. Östrus siklusunun tesadüfi aşamalarında, ineklerin (n=42) ovaryumları ultrason (US) ile muayene edilerek ≥3 mm tüm folliküller sayıldı. Üç-8 mm çapında
