| Abstract | ||||
| Twelve lactating buffaloes with an average weight of 496.7 kg were divided randomly into three similar groups (four animals each). Each group was assigned randomly to one of the following three dietary treatments: Control ration (C) {60% concentrate feed mixture CFM+40% rice straw, fodder beet ration (FB) {40% CFM+20% FB plus 50 gm urea+40% rice straw} and fodder beet silage ration, (FBS) {40% CFM+20% FBS plus 50 gm urea +40% rice straw on DM basis. The experiment was extended for 90 days. The results showed that animals received FB ration recorded the highest values of DM, OM, CP, EE and NFE digestibility followed by FBS ration. The FB group had significant (P<0.05) increases in OMD and CPD, while FBS treated group had the highest values in CFD (P<0.05). Blood serum parameters of FB group had highest values of serum TP, albumin, A /G ratio, glucose and urea (P<0.05), the FBS group had the higher values of serum TP, Albumin, A /G ratio, glucose and urea(P<0.05) than those of control. The (FB) group recorded the highest values of daily milk yield in all periods with average 6.99 kg / head /d., followed by FBS animals (6.69 kg / h/d) then control group (6.51 kg / h /d). The same trend was noticed with significant (P< 0.05) increase in fat corrected milk (FCM) yield (10.02, 9.65 and 8.90 kg / h /d.) for FB, FBS and control groups, resp., FB group recorded the highest values ( P< 0.05 ) of milk total solids, SNF, TP and lactose content, while FBS treated animals had significant higher total solids content and non significant higher milk SNF, TP and ash content than the control group. The FB group had the lowest feed cost to produce one kg FCM (2.88 L.E.) followed by FBS treatment which recorded (2.9 L.E.), while the control group had the highest value (3.51 L.E.). Fodder beet group had the highest economical efficiency value (2.43) followed by FBS treatment (2.41) then the control group which had the lowest value (1.99). | ||||
