Influence du taux d’acide alpha-linolénique de l’aliment sur la teneur en oméga-3 et les caractéristiques hédoniques de la viande de lapin. Revue bibliographique

Several publications are dealing with the influence of the omega 3 level in the feed, more particularly the alpha-linolenic acid level, on the rabbit meat level in this fatty acid, but only few of them deal with the use of the flaxseed. This review is a synthesis of the effects of the level of alpha-linolenic acid brought by the flaxseed on the omega 3 level of the rabbit meat. It shows a direct connection between the alpha-linolenic acid level in the feed and the omega 3 content of the rabbit meat. Besides, this enrichment decreases the saturated fatty acids level, the omega 6 level and consequently the omega 6/omega 3 ratio below 4. In consequence, the contribution of around 0.65% of alpha-linolenic acid in the feed by incorporation of flaxseed in the feed allows to bring in average 967 mg of omega 3 for 100 g of back or 459 mg for 100 kcal and 1004 mg of omega 3 for 100 g of shoulder or 483 mg for 100 kcal and consequently to claim the allegation “rich in omega 3”. This enrichment doesn’t modify the hedonic characteristics of the rabbit meat.
