Abstract
This experiment was to evaluate the role of dietary inclusion of fish oil (FO) on productiveperformance and some blood parameters of New Zealand White rabbits (NZW). A total of thirty NZW male rabbits, 5 weeks of age , and mean body weight of 850 g were growing used. They were randomly divided into three treatment groups (G1, G2 andG3), 10 rabbits each in fivereplicates, of two rabbits. The fish oil was added to the basal diet at graded levels of 0.0, 0.75% and 1.5% / kg dietfor (control) G1,group 2 and group 3 respectively. At 13 weeks of age, blood samples were collected from three rabbits per each treatment to determine some plasma constituents .group.The results showed that dietary supplementation with FO had insignnificat effect on body weight,body weight gain, feed intake, and feed conversion ratio. However , LBW of rabbits fed the 1.5% FO – supplemental diet had significantly heavier body weight than the other groups .Plasma total lipids ,triglycerides, cholesterol, LDL , and HDL were significantly affeected dietary. Fish oil supplementation significantly increased HDL and decreased LDL levels .The o.75 % level of dietary fish oil significantly increased plasma globulin level and decreased A/G ratio indicative of improved immune responses of rabbits . It is concluded that, dietary FO supplementation had a significant impact in enhancing immunity without negative effects on performance of rabbits .The 0.75 %FO level is recommended for best results.
