Dietary supplementation of nano-selenium and nano-curcumin effect on lipid profile and growth performance in broiler chicken

The present study was conducted in Ven-Cobb broiler chickens to evaluate the dietary influence of nano-selenium (Nano-Se) and nano-curcumin on lipid profile and growth performance. A total of 360 broiler chicks were divided into four groups and each group comprised 90 chicks. Chickens kept in group Iwas fed with a broiler basal diet and it served as the control group. While chickens kept in groups II, III and IV were fed with nano-Se (0.3 mg/kg diet), nano-curcumin (200 mg/kg diet) and combination (0.15 + 100 mg/ kg diet) of both, respectively. The serum lipid profile was estimated on days 21^st, 28^th, 35^th and 42^nd. Significantly (P<0.05) higher levels of serum high-density lipoprotein cholesterol, Significantly (P<0.05) lower serum cholesterol levels were observed in Group III and IV compared to Group I. Significant (P<0.05) improvement in body weight and feed conversion ratio (FCR) were recorded in Group II and IV compared to Group I on sixth week. In Group III, nano-curcumin supplementation significantly (P<0.05) reduced the body weight with reduction in abdominal fat content and improved FCR was noticed. It is concluded that supplementation of nano-Seat 0.15 mg/kg diet and nano-curcumin at 100 mg/kg diet in broiler chicken feed improves the production performance and exertsa hypolipidemic effect in broiler chickens.
