Experiment (1):
About 100 kg of prepared corn stalks treated by 4% urea and sealed by air tight polyethylene sheets then kept for21 days.
Other 100 kg of prepared corn stalks treated by 4%urea with addition of 5% molasses and sealed by air tight polyethylene sheets then kept for21 days. Six healthy Baladi rams, were used in this work. They were about one year old and nearly similar in body weight (initial average body weight ranged from 30-40kg) they were divided into 3 similar groups (2 rams per each group), each group was housed separately in shaded pen 4*4 meter and randomly assigned to feed experimental rations as following: Group A: fed on concentrates mixture and control diet (berseem hay).
