Effect of Cloprostenol Treatment at Artificial Insemination on Sow Fertility

Reproduction in Domestic Animals, 2007
ContentsIn two experiments, we examined the effect of administration of cloprostenol at artificial insemination on fertility of multiparous sows. Lactation length was 21 days and only sows exhibiting estrus by 7 days after weaning were included. Cloprostenol was administered by IM injection (175 μg; n = 126) or supplemented in the semen dose (525 μg; n

A new chemoenzymatic synthesis of d-cloprostenol

Tetrahedron: Asymmetry, 2005
Abstract A new chemoenzymatic synthesis of d -cloprostenol based on the biocatalytical resolution of anti -2-oxotricyclo[2.2.1.0]heptan-7-carboxylic acid 1 has been developed. The resolution was attempted by different approaches: esterification or reduction of the acid and hydrolysis or reduction of the corresponding esters.

Use of Luprostiol and Cloprostenol for Induction of Parturition in Pregnant Goats

Reproduction in Domestic Animals, 2009
ContentPregnant goats were induced to parturition on day 145 of pregnancy, with three different protocols: group Cl (n = 19) was injected intramuscularly (IM) with 75 μg of the prostaglandin analogue R‐Cloprostenol; group L (n = 20) was treated IM with 7.5 mg of the prostaglandin analogue Luprostiol; group L50 (n = 18) was injected IM with 3.75 mg of ...

Treatment of a Case of Bovine Hydrops Allantois with Cloprostenol

British Veterinary Journal, 1981
SUMMARY A four-year-old Ayrshire cow with hydrallantois was treated with cloprostenol at approximately six months of gestation. The pregnancy was successfully terminated with no post-parturient complications apart from retention of the placenta. Subsequent insemination resulted in the birth of a normal, healthy heifer calf.

Development of a manufacturing route for cloprostenol sodium

1995
This chapter deals with cloprostenol sodium, the active ingredient in Estrumate, and a synthetic analogue of the naturally occurring prostaglandin F2α. It details the effectivity of cloprostenol sodium in the synchronization of oestrus, which led to its application in planned breeding in cattle.

Controlled breeding of dairy cows with cloprostenol.

The Canadian veterinary journal = La revue veterinaire canadienne, 2010
The percentage of dairy cows that were mated and became pregnant during a 42 day breeding period was not significantly different when animals were routinely observed for estrus and mated when detected (71%, n = 56), inseminated at estrus following a single injection of cloprostenol (72%, n = 29), or inseminated at a fixed time after two cloprostenol ...
