Utilization of sugar beet pulp biologically treated in sheep rations
Abstract: The present work was conducted to study the effect of biological treatments of sugar beet pulp (SBP) to improve the performance of small ruminants (sheep) using one of the following rations: R1: 50%CFM + 30% untreated SBP+ 20% rice straw (control). R2: 50%CFM + 30% SPB treated with T. harazmum + 20% rice straw. R1 50%CFM + 30% SBP treated with T. reesei + 20% rice straw. Two experimental trials were conducted: (1) Digestibility trial was conducted using nine mature local Ossimi breed rams divided in three groups (3 animals each) weighting with average body weight 55kg ± 2kg and 3 years old. R2 recorded (P<0.05) the highest digestibility coefficients for all nutrients and nutritive value subsequently R3 showed medium values of nutrient digestibilities while, R1 represented the lowest values in digestibility of all nutrients and the results showed a significant improvement (P<0.05) in digestibility coefficients of NDF, ADF and cellulose. No significant differences (P>0.05) among R], R2 and R3 in the values of rumen pH while, significant differences (P<0.05) were recorded among R], R2 and R3 in the values of NH3-N concentration and TVFA's. Results showed insignificant differences (P>0.05) among the three tested groups in all blood parameters. (2) Feeding trial, eighteen Rahmani lambs with average body weight 20.00 ± 0.30 kg/head were used in this trial. Lambs divided in three groups (6 animals each) and fed the three respective rations with the same regime of feeding in digestibility trial for 120 days according to NRC (1985) allowance. Results showed significant difference (P<0.05) in the average daily gain among lambs fed different tested rations. R2 showed the higher value of average daily gain than R1 and R3 also, R2 recorded the best value of feed conversion (10.95) followed by the R3 treatment (11.82) than the control (12.15).
