Abstract
Effect of Dietary Supplementation of Chromium Yeast Alone and in Combination with Antioxidants on Performance of Broilers
Highlights
Metabolism of glucose in birds is considerably different from mammals while blood glucose concentration is much higher in birds and insulin levels are low (Brooks et al, 2016)
Chicks were fed corn-soya based broiler mash maintained as control (T0), the basal diet supplemented with chromium at 0.5 mg Cr/kg diet from chromium yeast (T1), the basal diet + 0.5 mg Cr /kg diet from chromium yeast + 250 mg of ascorbic acid /kg of diet (T2) and the basal diet + 0.5 mg
T0= Control; T1 = basal diet supplemented with 0.5 mg Cr/kg diet; T2= basal diet supplemented with 0.5 mg Cr /kg diet + 250 mg of ascorbic acid /kg of diet; T3 = basal diet supplemented with 0.5 mg Cr /kg diet + 250 mg vitamin E /kg of diet
Summary
Metabolism of glucose in birds is considerably different from mammals while blood glucose concentration is much higher in birds and insulin levels are low (Brooks et al, 2016). Though birds do not require any dietary vitamin source as it can synthesize vitamin (Pardue and Thaxton, 1986) reported that particular environmental stressors could alter ascorbic acid utilization or synthesis in poultry. It is well documented that under stress conditions such as low or high environmental temperatures, humidity and high productive rate ascorbic acid synthesis is inadequate (McDowell, 1989). As per available literature scanty work has been done on combination of chromium yeast alone and in combination with ascorbic acid and vitamin E In this view, the present experiment was designed to study the effect of dietary supplementation of chromium yeast alone and in combination with antioxidants on feed conversion, growth and nitrogen retention in broiler chickens during the winter season. **500 gm contains Vit.A 12; 50 MIU; Vit.D3 2.80 MIU; Vit.E 30.00 g; Vit.K 2.00 g; Vit.B1 2.00 g and Vit.B2 2.00 g
