Estrus Synchronization and Post-Partum Management of "Mossi" Local Breed of Goat in Burkina Faso
Abstract
The "Mossi" dwarf goat is the local caprine breed most commonly reared (rared) by small holders in central and eastern Burkina Faso, in West Africa sudano-sahelian region. Manifestations of estrus, possibility of it's synchronization and post-partum anestrus were studied among this type of animals, in its natural eco-climatic environment, using various procedures of reproductive management. Results shows that low levels of progestagens (35 mg and 40 mg of Fluoro Geston Acetate-FGA-per vaginal sponge) and short period of treatment (12 days) leads to poor response on the females (estrus settlements <4 days post treatment, low synchronization rate after 72 h). Whereas sponges with 45 mg FGA each, applied during 18 days, produce better results for the same parameters. Post-partum anestrus (PPA) has been significantly reduced (44 tot 47 days vs 65 days for control) with "45 mg FGA + 300 lu PMSG" and "Early weaning (1 month) + male-effect" treatments, whereas "high energy at end of pregnancy" didn't affect it. These results emphasize some advantages of "mossi" dwarf goat, and identify majors issues for optimizing their production by appropriate and unexpensive reproductive management techniques in local conditions.
