Effect of treating wheat straw with urea and molasses on crude protein and crude fiber of it and blood metabolites of Dalagh lamb

This experiment was carried out to investigate the effects of urea-molasses treating on wheat straw quality and utilization of different percents of ammoniated wheat straw on Dalagh male lambs. Different levels of ammoniated straw were replaced in rations by 0,9, 18 and 27 percent. Twenty four Dalagh male lambs were used in a completely randomized design and divided in to 4 treatments. Each treatment consisted of 6 lambs during 84 days. Crud protein and fiber of feed stuff were measured. Blood was collected from jugular vein in first and end of experiment. Due to urea ammunition, the CP content of wheat straw increased from 3.4 to 7.5 percent, and NDF, ADF decreased from 70.02, 47.4 to 61.2, and 41.3 percent, respectively. The results of current study showed that, serum glucose was not affected by treatments significantly (P>0.05). Serum urea at the beginning of the experiment for each treatment was 18.9, 28.8, 23.07 and 26.1 respectively. This results showed a significant increase in each treatment compare to control (P<0.05). The mean values of urea were not affected significantly (P>0.05) at the end of the experiment. It could be concluded that ammoniated wheat straw treated with molasses had not adverse effect on blood biochemical parameters and it could provide more nitrogen for lambs.
