| Abstract | ||
| Thirty five Ossimi male lambs with an average LBW 35 Kg were divided randomly into five nutritional groups for 195 days fattening trial. Five iso-caloric and iso- nitrogenous rations based mainly on yellow corn, grease and biscuit residuals were tested. The control ration (R1) based mainly on 45% corn grains (C); (R2) 30% corn and 6.5% grease (G); (R3) 15% corn, 15% bakery by-product (DBP) and 6.5% grease; (R4) 15% corn and 30% (DBP), while R5 was 45% (DBP). Results indicated that; lambs fed rations based mainly on (DBP) and (G) showed higher (p<0.05) DM and OM digestibility. Highest (CP) digestibility (p<0.05) was shown by lambs fed diet contained 30% DBP, however the lowest (P<0.05) CP digestibility was obtained by R5. Results of CF digestibility pointed out to insignificant differences among different experimental rations. Grease and (DBP) supplemented groups recorded higher (P<0.05) EE digestibility. Insignificant differences among different groups, neither in daily nitrogen intake nor in nitrogen retention (g/h/d).Four hrs. post feeding; higher (P<0.05) ruminal pH values were shown by lambs fed ration contained grease, while the control recorded the lowest one, but the highest (P<0.05) NH3-N value. Although, different experimental rations indicated insignificant NH3-N concentration. Grease rations showed lower (P<0.05) TVFA’s, however the control indicated higher (P<0.05) value. Different experimental groups indicated insignificant LBW gain, while animals fed ration contained 45% (DBP) recorded the best (P<0.05) feed conversion ratio. | ||
