The present invention is directed to compositions and methods for increasing the reproductive performance of breeding populations of swine. The swine feed compositions of the present invention are animal feed blends including marine animal products such as a fish oil or fish meal products. Methods include administering to the female swine a biologically effective amount of the swine feed composition comprising marine animal products wherein the marine animal products contain omega-3 fatty acids or esters thereof that serve as a source of metabolites in the female swine, to improve reproductive performance of the female swine. The methods can also be used to increase the fertility of a male swine, and can be used to increase the reproductive performance of both male and female animals by feeding the swine feed composition to both the male and female swine.

Cette invention a trait à des compositions et aux procédés correspondants permettant d'améliorer la fonction reproductrice de populations reproductrices porcines. Les compositions d'alimentation porcine selon l'invention sont des mélanges alimentaires animaux renfermant des produits issus d'animaux marins, tels que de l'huile ou de la farine de poisson. Les procédés selon l'invention consistent à administrer à la truie une quantité efficace du point de vue biologique de cette composition alimentaire porcine renfermant des produits issus d'animaux marins. Ces derniers contiennent des acides gras oméga-3 ou des esters de ceux-ci servant de source de métabolites chez la truie et ce, afin d'améliorer la fonction reproductrice porcine. Il est également possible d'utiliser ces procédés pour augmenter la fertilité du verrat, comme il est possible de les utiliser pour améliorer la fonction reproductrice des populations mâle et femelle en leur administrant cette composition alimentaire porcine.
