Twenty-eight Barki male lambs with average initial live body weight (LBW) of 31.75 kg and about five month of age were divided into four similar groups in live body weight and age (eight animals each). The first group (T1) was fed basal diets which composed of concentrate feed mixture (CFM) and untreated rice straw (RS), while the second group (T2) was fed basal diets which composed of concentrate feed mixture (CFM) and berseem hay (BH). The animals of the third and fourth groups (T3 and T4) were fed on the concentrate of first group (T1) plus either chemical treated rice straw (CTR) or biological treated rice straw (BTR), respectively.
