Study was conducted to evaluate the supplementation of jerusalem artichoke (JA) in broiler diet at the levels 1, 2, 3 or 4 percent compared with control or control fortified with chlortetracycline (CTC) on live performance, carcass quality, breast meat fat and cholesterol content and also health status on hematocrit (HTC), serum alanine aminotransferase (ALT) and cholesterol content. Feeding JA and CTC at the levels of 1 to 4 percent showed both better increased in body weight gain (BWG) and better improvement in feed efficiency but did not differ significantly (P GT 0.05) from control group for all periods of feeding. Breast meat fat content was decreased (P LT 0.01) and also breast meat cholesterol trended to decrease (P GT 0.05) when compared with the control group. No significant effect of JA and HTC, but ALT and cholesterol in chicks serum showed significantly decreased (P LT 0.05) when fed all levels of JA and decreased (P LT 0.05) when fed at 3 percent JA in the diet. Mortality was reduced when JA and CTC were fed. Feeding JA at 3 percent in broiler diet demonstrated beneficial in both BWG, feed efficiency and mortality for alternative replacement of CTC for antibiotic growth promoter.
