EFFECT OF SUPPLEMENTATION BROILER DIETS WITH DIFFERENT LEVELS OF POLYUNSATURATED FATTYACIDS ON PRODUCTIVE AND SOME BIOCHEMICAL TRAITS

Abstract

Abstract The study aimed to evaluate of adding multiple sources of polyunsaturated fatty acids (PUFA’s) to diets and their effects on productive performance and some biochemical traits of broiler. The study was conducted at the poultry farm belong to department of animal production/College of Agriculture-University of Anbar from 26/12/2017 to 6/2/2018 (42 day). A total of 210, One-day old unsexed Ross (308) chicks with average weight 40 gm., were randomly distributed to seven treatments with three replicates per treatment (10 chicks/ replicate). Birds in T1 were fed a basal diet used as control, T2 included addition of Conjugated Linoleic Acid (CLA) with (3 gm/kg feed), T3 included addition of Flaxseed Oil (FXO) with (3 gm/kg feed), T4 included addition of Fish Oil (FO) with (3 gm/kg feed), T5 included addition of (CLA) and (FXO) with (1.5+1.5 gm/kg feed)respectively, T6 included addition of (CLA) and (FO) with (1.5+1.5 gm/kg feed)respectively, T7 included addition of (CLA), (FXO) and (FO) with (1+1+1 gm/kg feed)respectively. All diets were formulated to meet the same requirements. Broiler were fed with water and feed ad libitum. The data of Body Weight Gain (BWG), Feed Consumption (FC) and Feed Conversion Ratio (FCR) were recorded weekly. The results of supplementation CLA, FXO and FO with (1+1+1 gm/kg feed) respectively (T7 ) had significant increase (P<0.05) in live body weight, Body weight gain accumulative and relative growth rate as compared with T2 addition of (CLA) with (3 gm/kg feed) and T1 (Control). Also results revealed significant improvement in Accumulative feed conversion ratio of birds in T2 , T3 , T4 , T5 , T6 and T7 comparison with T1 (Control). No significant differences recorded between treatments in Feed consumption and Blood biochemical traits included: Globulin, Albumin, Glucose, High density lipoprotein (HDL), Low density lipoprotein (LDL), Very low density lipoprotein (VLDL), Triglycerides (T.G) and Cholesterol (T.Chol.) at 42 days of age.
