| Abstract | ||
| Twenty male Awassi lambs of 23.75 Kg intial body weight (BW) were used .The lambs were randomly distributed in individual motabolit cages in to five groups (4 lambs each) to evalute of two levels of exogenous fibrolytic enzymes (safizyme) on digestibility of nutrients. All animals were fed: wheat straw ad libitum but knowledge the residue of it, the concentrate were give 2.5% of (BW) to cover their maintenance requirement. The enzymes were given in two levels (1,2) gm/kg either to wheat straw or to concentrate. The result showed that insignificant effects on digestibility of dry matter (DM) , nitrogen free extract (N.F.E), crude fiber and showed significant effect on digestibility of crude protein (C.P) and ether Extract (E.E) and the evalues to Crude protein were %57.87,% 60.94 ,% 71.35,% 64.95, %17.27, and to Ether extract were %50.53,% 52.23,% 54.07, %65.94,% 34.80, to all treatment respectively. | ||
