The present invention relates to a method of feeding carnitine supplemented diets to sows during the period of gestation or during both gestation and lactation periods. The method enhances pork productivity by increasing litter and pig birth and weaning weights. reducing the number of stillborn pigs and increasing the number of pigs born alive in the subsequent reproductive cycle. Sow diets of this invention include carnitine. such as L-carnitine or L-carnitine salts. Carnitine is generally added to the swine feed formulation in the amount of from about 5 to about 5,000 ppm.

Cette invention a trait à un procédé de nourrissement par adjonction de rations supplémentaires de carnitine au régime alimentaire de truies durant la période de gestation ou durant les périodes de gestation et de lactation. Cette méthode permet d'accroître la fertilité porcine du fait de la multiplication du nombre de sujets par portée, de l'augmentation du poids du porc à la naissance et du poids au sevrage, de la diminution du nombre de porcs mort-nés et ainsi que de l'augmentation du nombre de porcs nés vivants lors de la mise bas suivante. Les régimes alimentaires de l'invention comportent de la carnitine, de la carnitine-L ou des sels de carnitine-L notamment. La carnitine est, d'ordinaire, ajoutée à la formulation alimentaire sous des quantités comprises entre environ 5 et environ 5 000 ppm.
