Chemical Composition, Vitamin and Fatty Acid Profile of Meat from Carcass Cuts of Indigenous Goat in Tunisian Arid Land

Abstract

: The experiment was conducted to find out the nutritive value of different cuts of goat carcass. Ninety samples (6 cuts (shoulders, breasts, legs, rack, loin and necklaces)×3 diets×5 kids/diet) were used. Animals were divided according to 3 diets (SOL group: kids received Stipa tenacissima +olive leaves, OH: kids received oat hay and GH group: animals received grass hay). This research made to compare physicochemical quality and fatty acid of meat of cuts for kids feed by different diets. Results obtained showed that the chemical composition was not affected by the diet, exception to phosphorus which was higher in SO group (60.81±1.86). On the contrary, exceptions to protein content, other physicochemical parameters have been varied between cuts. Colors were higher in the shoulders compared to other cuts. The diet did not affect fatty acid profile but was varied between cuts, especially, omega 3 and omega 6 which were higher in the legs followed by the rack. The different cuts were rich in vitamin B; the breast was poorer in water-soluble vitamins.
