Abstract
The objective of this study was to determine the effects of vegetable fat sources on growth performance, blood cholesterol and hematology in broilers. A total of 90 d-old male broiler chicks (Cobb 500), were divided into 3 treatment groups. The experimental design was completely randomized design (CRD). Each treatment consisted of three replicates of ten each. The treatments were supplemented with palm oil (T1), soybean oil (T2) and krabok oil (T3) in broiler diet during 42 days. Results indicated that supplementation of different types of vegetable fat significantly differences (P<0.05) affect body weight, body weight gain, FCR and productive index (PI) of broilers. The highest live weight, PI and least FCR were found in krabok oil supplemented group. Carcass percentage was tended (P=0.056) improved highest in krabok oil treatment. Blood cholesterol and triglyceride levels were not significantly (P>0.05) among treatments. Heterophill, lymphocyte and ration of heterophil and lymphocyte were significantly decreased (P<0.05) by soybean oil. It was concluded that krabok oil supplement significantly increased growth performance in broilers as compared to palm and soybean oil supplements.
