Sixteen Rahmani rams average 25 kg were randomly distributed into four
similar groups. four in each. The first group received concentrate diet containing
linseed meal and rice straw (RS) ad-libitum. the 2nd group received concentrate diet
containing ground berseem seeds (G-BS) and RS, the 3t diet containing ground berseem seeds soaked in urea solution (BS-U) plus rice straw
ad-libitum and the 4th group received concentrate diet containing ground berseem
seeds soaked in EM1 (BS-M) plus RS ad-libitum.
Inlake from concentrate, roughage and concentrate roughage ratio (kg/h/d on
dry matter basis) were almost similar in all experimental rations, however, total OMI
slightly decreased with the group fed G-BS compared to others.
The rations containing BS-U and BS-M had the highest (P values for OM, OM and gross energy digestibility compared to G-BS and control diet,
except OM digestibility in control rations. The digestibility of EE was increased with
added both treated or untreated screening seeds compared to control diet. No
significant differences were detected for digestibilities of CP, CF, NFE, and CWC's
among all treatment with replacement linseed meal with screening seeds. The values
of TON% and OE Mcal/kg were increased with added treated screening seeds
compared to untreated seeds or control diet. . However no significant difference were
found in OCP% among all experimental diet.
The values of pH, lYFA's, acetic acid and valerie acid molar proportion were
not significantly different (P butyric acid proportion were lower (P than control diet however, iso-butyric acid and iso-valeric were significantly higher
(P M. The concentration of TN, TPN, NPN, NH3-N and MPN were not significant
(P>O.05) among all experimental rations. Blood serum values of TP, Albumin.
globulin, NH3-N, alkaline phosphates, AL T, AST and blood urea nitrogen were not
significant differ with replacement linseed meal with SBS.
Average daily gain and total gain of the control group were not significantly
different. Feed conversion as kg OM I kg gain, kg TON I kg gain, Mcal OE I kg gain
and g OCP J kg gain were not significantly different among all experimenlal groups In
conclusion these results indicated that replacement of linseed meal in the lambs
faltening diets, would improve the revenue and production efficiency.
