Synchronization of nitrogen and energy and its effects on the male ghazel lambs growth performance

For the purpose of determining affections of synchronization of energy and nitrogen on performance of growth of the male Ghezel lambs, the experimental in the form of CRD, it contains four treatments a) the enrich straw wheat with urea + the complete grain barley, b) the enrich straw wheat with urea + the crushed barley, c) the enrich straw wheat with urea + the crushed barley+ molasses, d) the enrich straw wheat with urea + molasses) performed in four replications, also the alfalfa as a roughage was equal in all treatments, and the nurture last 70 days. According to the treatments (b) and (c) the lambs gain weigh respectively 57 and 57.5Kg in comparison with treatment (a) that the lambs gain weigh 52 Kg, were difference significantly(p<0.0001). Performance of lambs in treatment (c) in comparison with treatment (a) was significant (p<0.0001). It was concluded that treatment (c) and (b) have the best performance. Also, the feed conversion ratio among treatments, treatment contain the crushed barley and the crushed barley with molasses has the best of feed conversion ratio (p<0.05). With regard to treatment (b) and (c) have more less amount numerical that is 5/4.
