Ovulatory follicle size and mucus ferning level in relation to non-return rate during artificial ınsemination time in spontaneously oestrus signed cows

Bu çalışma geri dönmeme oranı üzerine follikül çapının ve klinik muayenenin etkisini karşılaştırmak ve saha şartlarında alternatif olarak gebeliğin elde edilmesi üzerine östrus belirtilerinin mi dominant follikül (DF)’ün mü daha pozitif etkili olduğunu araştırmak amacıyla yapılmıştır. Östrusun klinik bulguları görsel ve bazı klinik testlerle değerlendirildikten sonra bütün hayvanlar donmuş-çözünmüş sperma ile sun’i olarak tohumlandılar. Geri dönmeyenlerin oranı (GDO) ortalama % 67.08 olarak bulundu ve GDO üzerine DF’ün (P

Spontan olarak östrus gösteren ineklerde sun'i tohumlama esnasındaki dominant follikül büyüklüğü ve mukus kristalizasyon düzeyinin geri dönmeyenlerin oranı ile ilişkisi

The present study was conducted to compare the effect of follicle size and clinical examination on non-return rate (NRR) and to investigate whether the oestrus signs or ovulatory follicle sizes (OFS) have positive effect on pregnancy success of cows in field conditions alternatively. The clinical findings of oestrus in animals were examined by visual observation and some clinical tests undergoing spontaneous oestrous cycles and then, all cows were artificially inseminated (AI) by frozen-thawing semen. The overall mean value of NRR was obtained as 67.08 % in all cows, and also the NRR was affected by size of the ovulatory follicle (P
