摘要

The study was conducted to evaluate enzose (corn dextrose), a corn milling byproduct, as substitute for corn grain as energy in growing lambs. Five iso-caloric and iso-nitrogenous diets were formulated. The control diet (E0) had no enzose whereas enzose replaced 20, 40, 60 and 80% corn grain in E20, E40, E60 and E80 diets on the basis of energy supply, respectively. Fifty growing lambs were divided into 5 groups, 10 animals in each, in a randomized complete block design. Nutrients (dry matter, crude protein, neutral detergent fiber and acid detergent fibre) intake and digestibilities increased with gradual replacement of corn grain by enzose. Lambs fed E80 diet also retained higher nitrogen (N) than those fed E0 diet. Plasma glucose, T-3 and T-4 increased while urea N decreased in lambs receiving higher enzose content. Maximum weight gain was recorded in lambs fed diets containing maximum concentration of E as a replacement for corn grains. A better feed conversion ratio was recorded in lambs fed E80 compared with those fed E0 diet. The study suggests that enzose can be used as an economical feed ingredient to replace corn grain upto 80%, without any adverse effects on growth performance of growing lambs.
