This study investigated the estrus synchronizing potentials of Luchis Estrus Milk (LEM), made from different varieties of Arachis hypogaea namely: Tennessee white, Tennessee red, Valencia and the Nigerian varieties in WAD goats and sheep. Forty animals were divided into 5 groups of 8 animals each with each group consisting of 4 goats and sheep were treated with LEM at a dose of 5ml/kg body weight. Results obtained revealed a significant level (p<0.05) of estrus synchrony in all groups treated with LEM made from Tennessee white, Tennessee red, Valencia and the Nigerian varieties with87.50, 100, 100 and 87.50% estrus inductions and 87.50, 75, 87.50 and 100% conceptions respectively. The result of the study suggest that LEM may contain active pharmacological substances capable of inducing estrus in goats and sheep and raises hope for the development of a new, readily accessible and cheap estrus synchronizing agent for all seasons production of goats and sheep as opposed to prostaglandin and other estrus agents which may not be easily available in local communities of Africa and takes longer duration to achieve etrus.
