Abstract

These studies were conducted to investigate the effect of dietary supplemental lincomycin at different food waste supplements on performance of broiler chicks. Diets were based corn, soybean meal and contained 3,100kcal/kg ME, 21% CP for the rest two weeks. Three levels of dietary lincomycin(LM; 0,2.2, 4.4mg/kg) and food waste(FW; 0, 7.5, 15%) were respectively inclusion in both experiments. In experiment 1, weight gain of birds fed 4.4mg/kg LM was significantly higher than no LM treatments(P<0.05). It tended to increase in 7.5% food waste treatment compared to that of control, but was not significantly different. FCR of chicks fed 2.2mg/kg LM supplement was significantly improved compared to that of other treatments Chicks fed food waste showed inferior FCR to control as dietary FW level increased(P<0.05). There was no significance in blood components among treatments. In experiment 2, weight gain of chicks fed 15% FW exhibited higher weight gain than that of other treatments. As FW supplement increased, the feed intake increased significantly(P<0.05) There was no significance in blood components except serum calcium. The results of these experiments indicated that hicks fed 4.4mg/kg LM supplements maximized growth rate of all treatments, and improved FCR in 2.2mg/kg LM.
