Effect of feeding growing-fattening rabbits a diet supplemented with whole white lupin (Lupinus albus cv Amiga) seeds on fatty acid composition and indexes related to human health in hind leg meat and perirenal fat

A total of 20 weaned rabbits (33 days old) (10 per treatment) were fed one of two diets that included 150 g of sunflower meal (SF)/kg of diet or 120 g of whole white lupin (WL)/kg of diet for 42 days The WL diet contained less saturated fatty acids (SFA) and polyunsaturated fatty acids (PUFA) but more monounsaturated fatty acids (MUFA) than the SF diet The WL diet significantly decreased SFA and PUFA content as well as the PUFA n - 6/PUFA n - 3 ratio and saturation atherogenic and thrombogenic indexes in hind leg meat The fatty acid composition in perirenal fat was similar to that of hind leg meat however significantly higher MUFA levels were observed in rabbits fed the WL diet Thus feeding rabbits the WL diet affected the fatty acid profile of hind leg meat and perirenal fat in a favourable manner (C) 2010 The American Meat Science Association Published by Elsevier Ltd All rights reserved
