Effect of prostaglandin F2α and GnRH administration at the time of artificial insemination on reproductive performance of dairy cows

The present study aimed to determine the effect of administrating prostaglandin F2α (PGF2α) and GnRH at the time of artificial insemination (AI) on the pregnancy per artificial insemination (P/AI) and the pregnancy survival rate of dairy cows. A number of 830 lactating Holstein cows were randomly divided into four groups. Cows in group 1 (n=200) treated with 150 µg d-cloprostenol. In group 2 (n...

Prostaglandin F2α promotes ovulation in prepubertal heifers.

The objective was to determine the effects of exogenous prostaglandin F(2α) (PGF), with or without progesterone treatment, on first ovulation in prepubertal heifers. We tested the hypothesis that PGF has a luteolysis-independent ovulatory effect in cattle. Crossbred Angus heifers (12 to 14 mo old, 250 kg body weight, and an average body condition score of 3 out of 5) were examined by transrecta...

Placental Origin of Prostaglandin F2α in the Domestic Cat

In the present study, the question was addressed whether the feline placenta can synthesize prostaglandin F2α (PGF2α). The PGFS protein was elevated, particularly at 2.5-3 weeks of pregnancy compared to 7-8 (P < 0.05) and 8.5-9 weeks (P < 0.001). Transcripts for PGFS were significantly upregulated at 2.5-3 weeks of pregnancy and then gradually declined towards the end of gestation (P < 0.001). ...
