The effects of laurel (Laurus nobilis L.) leaf powder supplementation on performance, carcass characteristics, meat lipid oxidation and some blood parameters of broiler chicks

The purpose of this study was conducted to evaluated the effects of bay laurel (Laurus nobilis L.) leaves powder (LLP) on performance, thigh and breast meat lipid oxidation and chemical composition, body components, digestive tract parts and some blood parameters in broiler chickens. A total of 144 d-old mix-sexed chicks were weighed and randomly assigned to four experimental groups with three replicates of 12 chicks (6 ♀and 6 ♂) each. Treatments were as follows: (i) basal diet-no additive (control), (ii) basal diet+1000 mg/kg LLP, (iii) basal diet+5000 mg/kg LLP and (iv) basal diet+10000 mg/kg LLP. The results revealed that over entire the experimental period body weight and body weight gain increased by LLP supplementation (P
