Effects of dietary pine cone meal on growth performance, serum cholesterol, carcass quality and fatty acid composition and cholesterol content of meat in broiler chickens

摘要

This study was conducted to evaluate effects of dietary pine cone meal on growth performance, serum cholesterol, carcass quality and fatty acid composition and cholesterol content of meat in broiler chickens. Three treatments were assigned to 480(2 days) Arbor Acre broiler chicks with eight replications, allocating 20 broiler chicks in each replication. Dietary treatments included 1) CS (1% cottonwood sawdust), 2) PCM0.5 (0.5% cottonwood sawdust + 0.5% pine cone meal) and 3) PCM1.0 (1% pine cone meal). During the overall period the difference of growth performance was not significant among treatments (P>0.05). Also, cholesterol profile(total, HDL, LDL cholesterol and triglyceride) in serum and carcass characteristic were not affected by treatments (P>0.05). TBARS of leg and breast meat was significantly decreased (P<0.05) in PCM1.0 treatment compared to CS treatment. In fatty acid contents of leg meat, C20:0 was significantly higher in PCM0.5 treatment than PCM1.0 treatment (P<0.05). Also, C18:3n3 was significantly lower in PCM1.0 treatment than other treatments (P0.05). Cholesterol contents of leg, breast meat and abdomen fat were not significant among treatment (P>0.05). In conclusion, results of the experiment were affected by dietary supplementation of pine cone meal on TBARS of leg and breast meat.
