Abstract

II is extremely necessary 10 utilize the locally available resources in order
to face the shortage in feed resources. This study was carried out to examine
the feed value of Abou-Rukba (Digitaria sanquinalis L) as a 10 ar feed
resource and animal performance when fed this grass.
Fifteen mature Rahmani rams (Ave. 46.2. ± 1.08 Kg live body weight) were
divided inlo five groups 0' there animals each and used repeatedly in 15 m~tabolism
trails. Several roughages (Abou - Rukba hay. corn stalks, bean straw, wheat straw)
were used as basic feedstuffs for sheep along with concentrate feed mixture (CFM).
All roughages except for Abou-Rukba were urea -treated. Roughage portion rations or
offered ad - fib whereas CFM portion was red at 1% or 1.5% of body weight, Abou-
Rukba ratiOM, tended \0 Increase nutnent digestibility. feeding values, nitrogen
balance, blood plasma parameters over other roughages, especiaUy when CFM level
increased from 1 % to 1.5%. The rumen liqoor parameters (pH. VFA's, and NH,-N)
were nearly similar among groups. Therefore, it may be conduded that, Abou-Rukba
hay may be used in sheep ralions when it is available 'or feeding.
