Two feeding trials were conducted at Bako Research CenterBRC). Lambs feeding tial was done from 13-05-1999 to 30-06-1999 while growing bulls feeding trial was conducted from 23-06-2000 to 06-06-2000. Both trials were performed with an objective to evaluate the effect of improved forages and/or concentrate supplementation on live weight of Horro lambs and growing bulls. A total of thirty-two ram lambs with similar initial live weight with mean 21.8 plus or minues 0.55 kg were allotted to four dietary treatments. Similarly, thirty-two growing Horro bulls with mean live weight of 174 plus or minues 1.71 kg were systematically grouped in to four and randomly assigned to four dietary treatments.The range of average daily grain, dry-matter intake, and feed conversion efficiency were 30-121 g/d274.2 522 g/d6.44for lambs, respectively. The ADG of lambs fed on improved forage and concentrate supplements (T2, T3, and T4) gave significantly (p0.05) higher mean when compared to lambs fed on the control diet (T1).
