The Effect of High Doses of Fish Oil as A Source of (Omega-3) in The Production and Physiological Performance in Local Rabbits

Abstract

The aim of this study was to investigate the effect of fish oil in some of the productivity and physiological traits in rabbits. This study was conducted using 14 local rabbit at( one month of age were divided into two groups) fed on a standard diet, the second group set at half ml of fish oil (treatment group) The first group remained without fish oil (control group) and this experiment continued for 21 days which divided into three experimental periods,the results showed significant decrease in feed consumption in the second group compared to the control group in the second and third experimental periods and the experiment as a whole. While there were no significant differences in both of weights and ratio of weight gain, and food conversion it has improved in the second group compared to the control in the third trial period only, was also observed a significant increase for second group in spleen weight and the percentage of the spleen and heart weight to carcass weight compared to control group. The rest cutouts carcass were not significantly affected, fish oil led to significant decrease in both the concentration of cholesterol and albumin and LDL and increases in the concentration of enzyme GOT, also led to a significant decrease in both the WBC, LYM, MID, GRAN, RBC, HGB , HCT, PLT, PCT and LPCR and increases value of RDW and the percentage of RDW in second group compared with the control group, while the rest of the physical and chemical blood components were not significantly affected by fish oil.
