| Abstract | ||||
| This study was carried out to investigate the possibility of utilizing the processed rice straw as an animal feed ingredient. Sixteen growing male Barki lambs were divided into four similar groups. The groups were assigned at random to receive one of the four experimental rations. All four rations consisted of a concentrate mixture in a mash form (50%). and roughage - urea mixture (50%). The roughage - urea mixture was made of rice straw (76%), wheat bran (12%) , molasses (10%) and urea (2%). Treatments represented different forms of the roughage -urea mixture. It was offered mixed with no treatment (R1) , ensiled (R2) or made into a feed blocks (R3). In the fourth treatment (R4) both the concentrate and the roughage portions were mixed and blocked. The feeding experiment followed by metabolism trial was lasted for days along with studying fermentation in the rumen and some blood metabolites. Results showed that ration R4 resulted in higher OM intake and rate of OM and CP digestibilities. Animals fed R2 and R4 had the highest values of nitrogen retention. Growing sheep fed R4 had higher values of digested nutrient Intakes expressed as TON Intake g/Kg BW (19.6) and OCP intake g/l(g BW (2.90). Animals fed R4 (Blocked) had the highest values of average daily gain (76 g/d) followed by those fed R2 (62 gld) (ensiled), while R3 resulted In the lowest AOG varues (44 g/d). Processing of rice straw with concentrate feed mixture as feed blocks improved the performance of growing sheep. | ||||
