Effect of dietary nitrogen and carbohydrate sources on productive performance in sheep
Abstract: Fifty four growing male Ossimi lambs (averaging 19.8 Kg and 6-7 mo old) were used in a feeding trial to investigate the effect of dietary nitrogen and carbohydrate sources on productive performance in sheep. In addition. a digestibility trial and nitrogen balance were conducted to study the treatment effect on metabolism. rumen characteristics and carcass characteristics Feeding trial included 9 experimental groups. Six animals each. Experimental lambs were fed nine different diets randomly. Three different sources of dietary nitrogen were used in combinations with three different sources of dietary carbohydrate: Results indicated that interaction between dietary protein and carbohydrate sources had a marked effect on growth rate, feed efficiency and some rumen, characteristics Among dietary protein sources urea caused the highest final body weight (43.9 Kg), ADG (197g) and feed efficiency (5.74 Kg DMI/kg gain), Corn as a dietary source of carbohydrate caused a higher (P<0.05) final body weight (43.8-Kg) compared with barley and basal diets. On the other hand barley caused less DM intake and a similar feed efficiency as corn which was better than basal diets. Combining hay and barley in the diets resulted in the highest final body weight and ADG. Feed efficiency values of lambs fed diets containing barley plus urea was the best. it was concluded that synchronization between dietary carbohydrate and protein degradation would maximize their utilization by ruminant animals.
