Abstract

The present paper pointed to investigate the effects of L-carnitine on broiler performance, carcass traits and some blood biochemical measurements. A total of 120 Ross chicks provided from hatchery, distributed randomly into four groups (30 chicks each) 3 replicates / each (10 chicks each). The 1^st was control group and received basal diet, 2^nd, 3^rd and 4^th groups fed basal diet containing 0.25, 0.5 and 0.75 g of L-carnitine per kg diet. Results showed that body weight (BW) at 42 days old and daily body weight gain (DBWG) through 21-42 and 1-42 days old showed promoting impact of checks received 0.25, 0.5 and 0.75 g L-carnitine /Kg diet than control group. Feed intake (FI) and feed conversion ratio (FCR) reducing significantly (P<0.05) compared with control group during stage 21-42 days of age. Comparative weights of carcass, dressing, giblets and liver were increased (P.
