The effect of adding cod liver oil to the diet on the productivity and blood parameters of broiler chickens

Abstract

The experiment was performed to evaluate the production performance and blood parameters of broiler chicken fed on cod liver oil enriched feed. A cohort of 96 day-old chickens was allocated at random into four treatment groups, denoted as T0, T1, T2, and T3. Each treatment group consisted of three replicates. In contrast to each replication consisting of eight birds, each treatment group comprises 24 birds. Experimental birds in T1, T2, and T3 were fed rations enriched with cod liver oil at 0.5%, 1%, and 2% by weight, respectively, whereas T0 received only standard feed and was designated as the control group. The findings of this research demonstrated that the final live weight and live weight gain of the birds in group T3 which was provided with feed enriched with 2% cod liver oil was significantly greater (p
