Vers une maîtrise de la reproduction sans hormones chez les petits ruminants

Abstract: Dans les élevages ovins et caprins, la maîtrise de la reproduction est importante pour une reproduction hors saison sexuelle, pour grouper les mises bas et pour la pratique de l’Insémination Artificielle (IA). Le traitement hormonal d’induction et de synchronisation de l’œstrus et de l’ovulation est aujourd’hui le moyen le plus efficace pour atteindre ces objectifs. Le recours à des traitements photopériodiques et/ou à l’effet mâle apparait comme une solution pour limiter l’utilisation d’hormones dans ces fili… Show more

“…In goat milk production, in France, the use of hormonal treatments, combining sponges and injection of PMSG-eCG made it possible to set up artificial insemination in the 70s and 80s and to use this means to select the best goats and bucks carrying favorable alleles of milk casein genes and thus increase milk production and cheese yield (Leboeuf et al, 2008). These treatments also make it possible to obtain fertilizations outside the sexual season that extends in Alpine goat breeds, from September to February (Pellicer-Rubio et al, 2019). These out-ofseason fertilizations make it possible to produce more milk due to the lengthening of lactation and to sell it at a more favorable season in terms of purchase price to farmers.…”

“…These out-ofseason fertilizations make it possible to produce more milk due to the lengthening of lactation and to sell it at a more favorable season in terms of purchase price to farmers. Every year more than 80,000 AIs are practiced using this technique and several hundred thousand goats are treated (Pellicer-Rubio et al, 2019). However, the repeated use of these treatments in the same animals leads, in some of them, to the appearance of antibodies against PMSG that neutralize the effects of the injected hormone (Hervé et al, 2004).…”
