dc.description.abstractIn the present study. the effects of dietary supplementation of niacin on daily feed consumption, body weight, food conversion ratio, egg production, egg weight, specific gravity, serum and egg yolk cholesterol and serum triglyceride concentrations were investigated in layer hens. A total of 490 27-week-old Brown-Nick layers was divided at random into 7 groups (of 70 hens) fed with diets containing 0, 50, 100, 150, 200, 250 and 300 ppm niacin for 90 days. Niacin supplementation have resulted in decreasing egg yolk, serum cholesterol and triglyceride concentrations (P<0.001). No significant difference between the controls and all the treated groups on damaged egg ratio and body weight was obtained but egg production, food intake. feed conversion ratio. and specific gravity values were affected by niacin treatment on some periods of the experiment (P<0.05). As a conclusion, dietary niacin supplementation markedly depressed lipid metabolism and particularly cholesterol metabolism and improved some zootechnical performances without deleterious side effect. The identification of biochemical pathways affected by niacin requires further investigations.en_US
