Reproductive records of the entire lives of two mares with abnormally high incidence of multiple ovulation and hemorrhagic anovulatory follicles were analyzed retrospectively. Chi-square analysis was used to test statistically the effect of cloprostenol, a prostaglandin F2 analog, on the incidence of multiple ovulations, hemorrhagic anovulatory follicles, and its ultrasonographic appearance. A ...

Oestrus was induced 4-7 days after treatment with Cloprostenol (ICI 80,996) in gilts between 12 and 40 days pregnant. Fertility at this synchronized oestrus was good (85%).

Stillbirth in swine ranges from 2 to 9%, resulting in a significant loss of piglets. Previous studies clearly indicate a relationship between prolonged birth intervals and stillbirth, but factors influencing birth intervals are not fully known. To characterize birth intervals and stillbirth, farrowing was recorded during three farrowing seasons. Blood samples were collected on d 110 and d 113 o...

The aim of the study was to evaluate the efficacy of aglepristone (10 mg/kg on days 1, 2 and 8) for the treatment of metritis or pyometra in bitches (n = 67) either alone for cases of metritis (n = 15), or in cases of pyometra (n = 52) with (n = 32) or without (n = 20) the addition of low doses (1 microg/kg) of cloprostenol for 5 days (days 3-7). Examinations performed on day 90, in addition to...

Results—We found that as many sows farrowed within a 48hour period following injection into the vaginal mucosa of 25% of the recommended dose as farrowed following intramuscular (IM) injection of the full dose. Experiment 2 confirmed the efficacy of the 25% dose when injected vaginally. However, when sows were injected perianally with cloprostenol, the 50% dose proved relatively effective, but ...

The efficiency of medroxyprogesterone acetate (MAP) and fluorogestone acetate (FGA) sponges with or without PGF2α (cloprostenol) for synchronizing estrous in non-lactating does was investigated during the natural breeding season. Does were treated for 11 days with 60 mg MAP (n = 38) or 40 mg FGA (n = 32) sponges. All does also received intramuscular injections of 500 IU PMSG. In addition, 19 an...

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...

The effectiveness of CIDR-B treatment for 12 days compared with the double injections of cloprostenol for oestrus synchronization in Kedah-Kelantan (KK) cows was evaluated. A total of 148 KK cows were used in three trials conducted at MARDI Research Station, Kluang, Johor. Cows were allocated randomly into two groups. Group 1 was given two injections IM of cloprostenol at 12 days apart; group 2...

Partus induction is an important integrative component of reproduction management in the swine industry. In this context, the question is to what extent the application of uterotonic substances may influence the vitality of piglets. The blood pH value is used as a laboratory objective diagnostic parameter of neonatal acidosis. This parameter of the acid-base balance was examined in piglets born...

four crossbred cows with mummified fetus were utilized for the study. the cows were subjected to gynecological examination and based on the findings the cases were diagnosed as mummified fetus. the cows were treated with 2 mg estradiol valerate and 500 µg cloprostenol and were examined every 12 hr after 24 hr of the treatment for cervical dilatation and other signs related to fetal expulsion. t...
