This experiment was conducted to investigate the effect of dietary supplementation of yellow loess on performance and blood component profile in broiler chickens. A total of three hundred sixty, 1 day old broiler chicks (Ross) were randomly divided into 3 groups with 4 replicates of 30 birds each. The experiment feeds were; control (basal diet), 0~10 days (basal diet with yellow loess T1 4%, T2 2%), 11~21 days (basal diet with yellow loess T1 2%, T2 1%), 22~35 days (basal diet with yellow loess T1 1%, T2 1%). The body weight and weight gain of the broilers fed T2 diet was significant higher than the T1 and control treatment (P less than 0.05). Feed intake was significantly higher than the control during overall period (P less than 0.05). Total cholesterol in all yellow loess supplemented treatments were significantly higher than the control treatment (P less than 0.05), and the triglyceride of broiler fed the diet containing T1 was significantly higher than the control and T2 treatment (P less than 0.05). No significant differences were observed on the total white blood cell (WBC), neutrophil (NE), monocyte (MO) and eosinophil (EO) in all yellow loess supplemented treatments compared to the control. Lymphocyte of T2 treatment was significantly higher than T1 and control treatment (P less than 0.05). No significant difference was observed on fecal ammonia gas emission, but broiler fed yellow loess was lower than the control treatment. Aa a result, dietary supplementation of yellow loess was improve to weight gain and feed intake of broiler.
