ABSTRACT
Fish oil (FO) is an excellent source of omega-3 fatty acids, which helps broilers gain weight and improve their immunity. The current study was done with special emphasis on establishing the impact of FO on improving the feed-conversion-ratio (FCR) and decreasing the rearing cost of broilers by feeding a commercial broiler-feed. A total of 120 unsexed commercial broilers (Ross-308) were randomly assigned to four treatment groups that contained 1%, 2%, and 3% FO in regular drinking water, as well as a control group. All of the birds were given enough commercial broiler-feed and water. The performance gained by broilers after 30 days of rearing from all supplemented groups complied with the standards. Observed parameters like live weight, feed intake, weight gain, and FCR of broilers were significantly higher in the 2% and 3% FO-supplemented groups. Data for cost-benefit analysis revealed significantly increased net profit in FO-treated groups. However, abdominal fat increased linearly with increasing levels of FO supplementation. The serum HDL level was increased, whereas cholesterol, LDL, and triglyceride levels were significantly decreased with increasing levels of FO in the broiler diets. It was concluded that supplying 2% or 3% would be effective in both increasing market weight and improving the profit of commercial broiler farming.
