| Abstract |
The aim of this investigation was to comparatively study the influence of changing the roughage type of the diet on the digestibility and growth performance of lambs. Twenty-one baladi male lambs of an average initial live body weight (LBW) of 22.15 ±0.111 kg/head were used after being divided into three similar groups. Animals were fed berseem hay, untreated or ureated barley straw ad-lib for groups 1 (control), 2 and 3 respectively. Concentrate feed mixture (CFM) and barley grain were each given at 1 % of LBW for all groups. Three digestibility trials were carried out with lambs. Results indicated that the digestibility of DM, OM, CP, EE and NFE and TDN and DCP values and nitrogen balance of berseem hay ration (G1-control) were significantly higher than those of other diets. Plasma total protein, albumin, globulin and rumen liquor pH value and TVFA's concentration were not significant among groups. Control group (berseem hay) had greater daily gain and the best feed conversion as kg DM/kg gain. while ureated barley straw ration (group 3) recorded the lowest cost/kg gain and the best economic efficiency. Under the circumstances of this study, it can be concluded that, ureation of straw improved its nutritive value and reduced costs of meat production in lambs and increased economic efficiency.
Keywords: lambs, clover hay, ureated barley straw-daily gain-digestibility- feed conversion, rumen fermentation in blood metabolites.
