Effect of using screening Berseem seed as a source of protein instead of linseed meal in fattening lamb rations
|

Abstract: 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 3rd group received concentrate 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.
Intake from concentrate, roughage and concentrate roughage ratio (kg/h/d on dry matter basis) were almost similar in all experimental rations', however, total DMI slightly decreased with the group fed G-BS compared to others.
The rations containing BS-U and BS-M had the highest (P<0.05) digestibility values for DM, 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 TDN% and DE Meal/kg were increased with added treated screening seeds compared t9 untreated seeds or control diet. However no significant difference were found in DCP% among all experimental diet.
The values of pH, TVFA's, acetic acid and valeric acid molar proportion were not significantly different (P<0.05) among all experimental diets. Propionic acid and' butyric acid proportion were lower (P<0.05) with animals fed treated or untreated SBS than control diet however, iso-butyric acid and iso-valeric were significantly higher (P<0.05) compared to different experimental diets except iso-butyric with added BSM. The concentration of TN, TPN, NPN, NH3-N and MPN were not significant (P>0.05) 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 DM / kg gain, kg TDN / kg gain, Mcal DE / kg gain and g DCP / kg gain were not significantly different among all experimental groups. In conclusion these results indicated that replacement of linseed meal in the lambs fattening diets, would improve the revenue and production efficiency.
