dc.description.abstract [EN] Biostimulation of lactating rabbit females, through time limitad controlled lactation, was comparad to a conventional PMSG treatment. Experimental groups were composed with females separated from their litters for O, 24, 36 or 48 hours befare being inseminated on day 4 or 11 post partum. When biostimulation was applied, results were improved comparad to non-stimulated females, especially fertility on day 4 post partum, after more than 24 hours of mother-litter separation (P<0.01 ). In either the 35 or 42 days reproductiva rhythm, a single mother-litter separation for at least 36 hours, prior to Al, resultad in comparable fertility and prolificacy to those obtained in females treated with 20 IU of PMSG. Although litter survival was not affected, daily growth was slowed down and weaning weight reduced by 10% when litters were not allowed to suck for 36 or 48 hours (P<0.01). lt is concluded that this technique could offer an alternativa method to PMSG treatment in commercial units, in splte of the decrease in growth. However it should be advisable to evaluate at a long term its incidence on global productivity. es_ES
dc.description.abstract [FR] L'intérét d'une méthode de biostimulation de lapines allaitantes, par un controle ponctuel de la lactation, est comparé a un traitement classique de PMSG. Les groupes expérimentaux sont composés de lapines séparées de leur portée depuis O, 24, 36 ou 48 heures, avant d'átre inséminées le 4eme ou le 1 teme jour apres la mise bas. Quand la biostimulatlon est appliquée, les résultats sont améliorés par rapport aux lapines non stimulées, particu/ierement la fertilité des lapines inséminées 4 jours post partum apres plus de 24 heures de séparation (P<0,01). Que/ que soit le rythme de reproduction, une séparation ponctuelle des meres et de leur portée d'au moins 36 heures avant l'insémination conduit a des résultats de fertilité et de prolificité comparables a ceux obtenus par un lot de lapines traitées avec 20 U./ de PMSG. Bien que la viabilité des lapereaux ne soit pas influencée par la biostimulation, la croissance journaliere diminue et le poids au sevrage est réduit de 1 O %, quand /'allaitement est suspendu pendant 36 ou 48 heures (P<0.01). Malgré cette chute de croissance, les auteurs concluent que cette technique pourrait etre une so/ution alternative au traitement PMSG dans les é/evages commerciaux. Cependant, il conviendrait d'évaluer son incidence a long terme sur la productivité g/obale.
