Serum lipids profile and production performance of broiler chicken fed Nilotic silver cat fish oil supplemented diet

Abstract EN

Fish oil has been used in poultry nutrition to improve performance However, the effect of feeding Nilotic silver cat fish oil had never been studied before.

Therefore, this study was designed to evaluate the effect of supplementing Nilotic silver cat fish oil in the diet on the serum lipids profile and production performance of broiler chickens.

A total of 90 unsexed one day old (Hubbard15) broiler chicks were used in this experiment.

Chicks were distributed in a completely randomized design with three graded levels of silver cat fish oil (0,4 and 6%) (Each treatment contained three replicates with 10 chicks each).

Significant (P < 0.05) improvement in total weight gain and feed conversion ratio in birds fed 4 and 6% Nilotic silver cat fish oil supplemented diets compared to those fed the control diet.

Dietary treatments had no effects on feed intake and mortality rate among.

.Birds fed 4 and 6% silver cat fish oil have lower (P < 0.05) cholesterol (CH )mg/dL, low density lipids cholesterol (LDL) mg/dL and total triglyceride (Poumès-Ballihaut et al.) mg/dL compared to the control group.

High density lipids cholesterol (HDL) mg/dL was not affected by Nilotic silver cat fish oil supplementation.

This study concluded that supplementing Nilotic silver cat fish oil in broiler diet significantly improved total weight gain, feed conversion ratio and decreased cholesterol level LDL and TG with no effect on HDL.
