An experiment was designed to examine the responses of the store lambs to different inclusion levels of urea treated wole crop wheat (UWCW) in grass silage (S) hased rations, in particular their effects on feed intake, growth and carcass characteristics. A well preserved UWCW was mixed with grass silage to replace, 100, 75, 50, 25 and 0.0 percent of forage dry matter. All forages were fed ad libitum with 450g concentrate per day to Iambs (30kg liveweight) over 16 weeks. The highest and the lowest DIM were obtained in diets, 4 "W25" and 1"WIOO", respectively. The ME concentration in the diets increased with decreasing level of WCW. The lowest ME and CP intake were found in diet 1 "W100" and the highest MEI and CPI were observed in diets 4"W25", control "S100", and 2"W75". DLWG and FCR were improved in lambs Fed diets 4 and I. The lambs which consumed diets 4 and 2 showed greater cold carcass weight, wherease the lowest killing out percentage was observed in lambs were fed on diets 1 and 5 however, the highest killing out % was recorded for diet 2. These results show that UWCW is not a suitable forage for feeding alone, WCW therefore, should be mixed with other forage for feeding to animals.
