Effects of Different Oil Sources on Performance and Fatty Acid Profile of Breast and Thigh Muscles in Broilers
Authors
Abstract:
This experiment was conducted to determine the effect of different vegetable oil types on broiler performance, carcass characteristics and fatty acid profile of breast and thigh meat. For it, a total number of 300 day-old cobb-500 broiler chickens were housed in floor pens for 42 days in a completely randomized design, consisted of 5 treatments (soy, flaxseed, canola, corn and sunflower), with 5 replicates and 12 chicks in each. At 43 days of age, after 4 hour of fasting, two birds from each replicate (a male and a female) were slaughtered by cervical dislocation and after carcass characteristic determination, sampling from male breast and thigh was done. Different vegetable oil sources had no significant effect on weight gain (1-42 day period), feed conversion ratio (1-42 day period) and carcass characteristics. Flaxseed oil increased UFA, PUFA, n-3 fatty acids, UFA:SFA ratio, PUFA:SFA ratio and decreased n-6:n-3 ratio in breast and thigh muscles (P<0.05). The highest content of n-6 fatty acids was observed in the thigh of the chickens fed corn and flaxseed oils and the lowest was seen in broilers received canola oil (P<0.05). The results showed that dietary oil source had no significant effect on feed conversion ratio but inclusion of flaxseed oil enhanced n-3 fatty acid content of broiler breast and thigh meat.
