Economic Analysis of Feeding Urea Ammoniated Sugarcane Trash on Performance of Narisuwarna X Kenguri - F1 Lambs

Abstract
An experiment was conducted for the duration of 140 days with fifteen Narisuwarna X Kenguri F1 strain of around 3-7 months age divided into five groups of three lambs each. Each group was randomly allotted to one of the five dietary treatments in a switch over design. Uniform managemental care like deworming, vaccination etc.,was under taken in stall fed condition. Sugarcane trash was procured, chaffed and subject for 4% urea ammoniation. Ad libitumroughage was fed to lambs and concentrates supplemented as per ICAR (2013) to lambs to meet maintenance level and to support 50, 100, 150 and 200g daily body weight gain. The total variable cost of lambs, labour, roughage, concentrate and miscellaneous cost per animal was 5131, 5593, 6031, 6354 and 6468 rupees in T-1,T-2, T-3, T-4 and T-5 respectively. The revenue generated from sales of lamb and manure per animal was 6005, 6274, 8303, 9303 and 8462 rupees in T-1, T-2, T-3, T-4 and T-5 respectively. The benefit cost ratio was 1.17, 1.12, 1.38, 1.46 and 1.31 in T-1, T-2, T-3, T-4 and T-5 respectively. Therefore it is concluded that feeding of ad libitum urea ammoniated sugarcane trash and feeding concentrate for 100-150g gain as per ICAR (2013) improved body weight gain and observed better economic returns.
