Abstract
Barley straw from four varieties ( Arabi Abied (AA), ERJApam
(ER), C63 (C63) and Beecher (BE) ) with and without
soybean meal supplement were compared for differences in
voluntary feed intake and digestibility. Two sets of Latin Square
Design with four mature Awassi male sheep were used.
The results showed that the mean intakes of barley straw were
41.2, 34.8, 30.6 and 25.6 g/kg W 0.75 for the four varieties AA, ER, C63
and Be, respectively and 41.7 and 24.4 g/kg W 0'75 with and
without supplementation of soybean meal, respectively.
However, there was a significant (P<0.05) difference between the
intake of AA variety and the other varieties of barley straw.
Supplementation with soybean meal increased apparent dry matter
digestibility, but this was not significant.
