The effect of cloprostenol and cloprostenol + HCG on corpora lutea and serum progesterone in Brahman cows

Theriogenology, 1982
Abstract Two independent trials were conducted to evaluate 1) the effect of cloprostenol (CLP; ICI 80996) on subsequent corpus luteum size and progesterone content and 2) the effect of CLP and CLP followed by HCG (1500 IU) at estrus on daily serum progesterone levels in Brahman cows.

An Improved and Efficient Process for the Preparation of (+)‐cloprostenol

Chirality, 2015
AbstractAn improved and efficient synthesis of (+)‐cloprostenol has been accomplished in nine steps and 26% overall yield from commercially available (–)‐Corey lactone 4‐phenylbenzoate alcohol 1. The present route avoids tedious purifications and requires only one column chromatography operation, which reduces the generation of waste and is suitable ...

Cloprostenol for termination of pregnancy in cattle

New Zealand Veterinary Journal, 1977
Summary Two hundred and twenty seven dairy cows and heifers which had conceived at least 245 days previously were treated with dexamethasone alone (20 mg i/m), cloprostenol alone (500 µg s/c) or both drugs at different time-combinations in order to study the effect in terms of induction of parturition.

Fertility of dairy cattle following oestrus and ovulation controlled with cloprostenol, oestradiol benzoate and progesterone or progesterone and cloprostenol

Journal of Steroid Biochemistry, 1983
There have been several approaches to the control of the timing of the oestrous cycle and ovulation in dairy cattle in the last three decades. The first phase involved the use of progestins which were administered in various forms for prolonged periods.

The Bovine Practitioner, 2003
This factorial study was conducted to determine the reproductive performance of402 dairy cattle treated with either dinoprost (25 mg) or cloprostenol (500 pg), intravenously (IV) or intramuscularly (IM), for synchronization of estrus in a randomized clinical trial.

CONTROL OF REPRODUCTIVE FUNCTION OF CATTLE USING CLOPROSTENOL

Australian Veterinary Journal, 1976
Two intramuscular injections of cloprostenol were given 12 days apart to synchronise oestrus in a group of 47 heifers and following the second injection, 38 were found in oestrus in 2 to 6 days, 1 in 11 days and 8 in 22 to 27 days. The conception rate of the synchronised animals was 24 of 38 (63%).

Use of cloprostenol as an abortifacient in the llama (Lama glama)

Theriogenology, 2000
As part of a larger project investigating the development and heritability of choanal atresia glama), it was necessary to develop a protocol for aborting llamas at various stages of gestation. Twenty-seven animals between 4 and 7 mo of gestation were successfully aborted a total of 53 times following two 250 microg intramuscular injections of ...

The induction of parturition in the bitch using sodium cloprostenol

Theriogenology, 2000
The objectives of this studies were to determine a continuous low-dose treatment regimen for the administration of sodium cloprostenol to the bitch that did not cause polydipsia, and whether this treatment would induce normal and timed parturition in bitches during late pregnancy.
