Effect of Using Different Levels of Rumen Degradable Protein (RDP) To Undegradable Protein (RUP) on some Performance and pH Rumen of the Awasi Lambs

Abstract

This study was conducted in the field of sheep at the college of Agriculture-University of Tikrit from 4/11/2012 until 19/1/2013 (77days). 20 Awassi Lambs were used in this experiment, they were bought from local market aged 4-5 months and average weight of 22.770.36± . These lambs were divided in to five groups according to their weight , each group had four lambs , then distributed the treatments randomly on groups .In this experiment individual feeding system was used which included five rations with different levels of rumen degradable protein (RDP) to undegradable protein (RUP) . Statistical analysis results showed that there was a significant increase (P<0.05) in the final weight , for the four and five groups compared with one and two and three groups . and showed a calculated increase in the daily weight and total weight gain for the four and five groups compared with one and two and three groups. Also the results showed that there was no a significant differences in the rumen PH for all groups.
