| ABSTRACT The study was aimed to evaluate corn steep liquor (CSL), a by- product of corn starch processing, as a potential substitute of urea and its influence on nutrients intake, digestibilities and economics of weight gain for growing lambs. Five experimental diets, CSL0, CSL20, CSL40, CSL60 & CSL80, were formulated to replace urea by CSL at the rates of 0, 20, 40, 60 and 80% on the basis of N supply, respectively. Fifty growing lambs were divided into 5 groups of 10 animals each in a randomized complete block design. Maximum and minimum dry matter (DM) intakes were recorded for lambs fed diets containing highest (CSL80) and null (CSL0) concentration of CSL, respectively. Crude protein (CP), acid detergent fiber (ADF) and neutral detergent fiber (NDF) intakes also followed the same trend. Digestibilities of DM, CP, NDF and ADF increased with ascending replacement of CSL to urea. Lambs fed CSL gained higher weight than those fed CSL0 diet. Maximum weight gain was recorded for lambs fed diet containing maximum concentration of CSL. Cost of feed per Kg live weight produced was slightly decreased if not being similar due to ascending replacement with CSL. However, feed conversion ratio showed the best value with CSL80, followed by CSL60 and CSL40 while the poorest with CSL0 and CSL10 (P < 0.05). The findings of the present study indicated significant increase in nutrients intake and weight gain without any adverse effects on growth performance of lambs when CSL was used up to 80% on N basis as replacement of urea. | ||||
