Effect Supplemented Conjugated Linoleic Acid in Pre and Post Hatching on Fatty Acid Ratio of the Thigh Muscle and Antioxidant Indicators of Broilers Chickens

Abstract
The effect of conjugated linoleic acid (CLA) in pre and post hatching stage on some blood biochemical and antioxidant, this study on 600 one-day-old broiler chicksT3, T4, T5 and T6. Injection in amnion sac at 18th day of incubation by 0.1%, 0.2%, 0.3% and 4% CLA. Diets containing 0.1, 0.2, 0.3, or 0.4 gm. CLA/kg diet for T7, T8, T9 and T10. Two control groups (injected with or without Commercial dilution solution) for T2 and T1. The results showed significant improvement in GSH level in plasma whatever no difference in MDA level in CLA treatment compared with T1 and T2 , and a significant improvement in GSH level in meat and significant decreasing in MDA and peroxide number(PV) levels in the meat of all CLA treatment when compared with the control treatments T1 and T2. The results showed a significant increase (p<0.05) in the percentages of the saturated fatty acids palmitic and stearic for all treatments when compared for with the control treatments. The unsaturated fatty acids linolenic and linoleic were found to respond differently as a response to the treatments.The former percentage increase significantly and the later percentage decrease significantly for some of the treatments that supplemented with CLA when compared with the T1 and T2. It can be concluded from the study an improvement in antioxidants when adding CLA and the percentage of saturated fatty acids (palmitic and citric) as well as the unsaturated fatty acid linoleic.
