Sunflower oil supplementation alters meat quality but not performance of growing partridges (Alectoris chukar)

This study was conducted to evaluate the effects of sunflower oil supplementation (0%, 3%, 6% and 9%) to partridge chicks (Alectoris chukar) on growth performance, nutrient digestibility and carcass characteristics. Feed consumption and live weight gain were responsive to dietary sunflower oil inclusion during the starter period, but not during the grower period. Increasing sunflower oil level linearly increased crude protein and fat digestibilities. Except for abdominal fat, weights of inedible parts and edible organs remained unchanged by the diets. The treatments linearly decreased weight and efficiency of carcass and weights of wings and breast and did not alter weights of thighs and neck. Breast meat saturated fatty acids decreased linearly by 17.9% and unsaturated fatty acids increased linearly by 10.6%, as sunflower oil level increased in the diets. Monounsaturated fatty acids decreased linearly by 27.3%, whereas polyunsaturated fatty acids increased linearly by 51%. Overall, n-3 (0.78% vs. 0.59%) and n-6 (42.6% vs. 29.8%) were greater in breast meat in treatment groups than in control group. In conclusion, sunflower addition into diets has minimal effects on performance of growing partridges, but significantly alters meat fatty acid composition. © 2009 Blackwell Verlag GmbH.
