Abstract
This experiment was conducted to compare the influences of dietary dried persimmon by-product(DPB) on performance, blood cholesterol and fatty acid composition in broiler chicks. Diets contained 21.5 and $19\%$ CP for the starting and finishing period, respectively. The ME was 3,100kcal/kg in diets for both starter and finisher diets. One hundred sixty chicks were assigned to 4 treatments with 4 replicates at different levels of dried persimmon by-product. Treatments were consisted of 0(control), 1(T1), 3(T2) and $5\%$ (T3) DPB. Body weight gain was higher in treatment groups fed the starter diet but was the lowest in T3 for finishing period. Feed efficiency was not significantly different. In proximate composition, crude fat of chicken meat were increased in diets by addition of DPB than control, but moisture and crude ash was no significantly different. The total cholesterol, HDL, and triglyceride of treatment groups was higher than control. The LDL of control was higher than treatment groups. In fatty acid composition, oleic acid contents of treatment groups were higher than control, whereas stearic, linoleic acid contents lower in meat composition than control. In conclusion, dietary supplementation of DPB at $3\%$ level tended to improve growth performance of broiler chicks.
