Objective: To describe some reproductive management programs that allow increasing the productive efficiency of ewes. Design/methodology/approach: Description main hormones and their application in sheep protocols. The subjects are reviewed based on academic references as well use protocols at Sheep Goat Reproduction Laboratory Colegio de Postgraduados, Mexico. Results: Hormones, socio-sexual s...

The administration of hormones to mares during breeding management is an essential tool for equine practitioners. Proper and timely administration of specific hormones to broodmares may be targeted to prevent reproductive disorders, to serve as an aid to treating reproductive disorders or hormonal imbalances, and to optimize reproductive efficiency, for example, through induction of estrus or o...

The association between steroid hormones and cancer has been a primary research focus for many years. Reproductive are of particular interest given the fact that several highly prevalent c...

Non-invasive endocrinology utilizes non-invasive biological samples (such as faeces, urine, hair, aquatic media, and saliva) for the quantification of hormones in wildlife. Urinary-based enzyme immunoassay (EIA) and radio-immunoassay have enabled the rapid quantification of reproductive and stress hormones in amphibians (Anura: Amphibia). With minimal disturbance, these methods can be used to a...
