0.05) increase for T2 ration than those of T1 and T3 .The energy concentration of tested diets showed significantly among treatments (P<0.05) and T3 ration had the highest values of NE , ME , and DE concentration ( 1.420 , 2.227 , 2.716) for T1 , T2 . T3 respectively . On the other hand, growth energy (GE) value of T2 rationhad decreased (1.765) than those of T1 ration (1.777) and T3 ration (1.760) .Finally , economic return of kids fed T1 ration showed the highest average feed cost / kg of BWG (14.45 LE) than T2 (13.51 ) and T3 ( 12.52) . Moreover, Price of body weight gain of T1 ration was higher (14.45 LE ) followed by T2 ( 13.51 LE) and the lowest price had recorded with T3 ration(12.52 LE). On the other hand Improved of economic efficiency (%) had recorded the highest value with T3 ration (12.40 LE ) while T2 ration had detected the lowest value (6.04 LE ) in comparison of control ration (T1 ) .]]>

0.05) increased live body weight , body weight gain , protein and energy efficiency ratios compared with kids fed other dietary treatment groups. Moreover, final body weight ( finishing period 60 days) the kids fed G4 and G3 rations were significantly (p>0.05) higher than those fed others tested rations. While feed intake as well as ( DM , CP ,TDN ,DCP, protein and energy) were significantly (p>0.05) higher for kids fed control (G1) followed by those fed barely x berseem silage ration (G2) than kids fed Rod grass x berseem silage(G4)and hybrid Napeir grass x berseem silage(G3).However feed conversion ratio was the best for Rod grass x berseem silage(G4)followed by hybrid Napeir grass x berseem silage(G3). Meanwhile , the results illustrated that kids fed Rod grass x berseem silage (G4) improved (p>0.05) most nutrients digestibility and feeding values as TDN and DCP compared with other tested rations .The average daily feed intake by kids fed control and barely rations during growing period were significantly (p >0.05) higher than others . Average daily feed intake by kids during finishing period showed that kids fed control (G1) and barely x berseem silage(G2) had the highest DM intake . However, kids fed ration contained Rod grass x berseem silage (G4) and hybrid Napier grass x berseem silage(G3)showed the lowest DM intake. It could be concluded that Rod grass mixing with berseem silage(G4) , hybrid Napier grass with berseem silage(G3) and barely with berseem silage(G2) as silages in growing kids nutrition led to improve digestibility of most nutrients, increase daily gain , feed conversion and higher economic return and economic efficiency during the whole fattening period . ]]>

0.05) the highest digestibility coefficients of CP , CF , EE , NFE and GE ( 76.94 , 64.91 ,74.82 ,74.13 and 66.25 respectively) while , T3 had higher values of DM , OMand lower of CP, EE, CF and GE ( 70.62 ,74.32, 74.91, 61.88, 72.94 , 72.24 and 64.17 respectively) and the lowest values had detected with T1 ration ( 68.97,71.37 , 75.28 , 63.17 , 72.56 , 71.61and 63.31 respectively ) . As milk yield , the results showed that the higher actual daily milk yield (ADMY) and 4% fat corrected milk yield (FCMY)were obtained with of dairy zaribi goats fed tested rations T2 (1.390 , 1.350 kg /d respectively ) than of those fed T1(1.168,1.119 kg/d ,respectively) and the lowest values were recorded with T3 ration (1.274 and 1.206 respectively). Moreover,T2 ration were significantly (p>0.05) increase of fat , total solid, total nitrogen, lactose and Net Energy (3.81 ,13.40 , 7.30 ,5.31 and 1.60 respectively), but it recorded the lowest values with % protein and solid nonfat (3.38 and 9.59 respectively) than those of other experimental treatments . Blood hematology explain that T3 ration had the lowest values of RBC, hemoglobin, MCV, MCH , MCHC , total protein , globulin , serum glucose and urea-N comparison of T1 and T2 rations. In addition, the results of economic efficiency were clearly that goats fed T2 ration had the highest value ( 12.03 %) and T3 ration ( 6.65) , whereas T1 ration had the lowest value. ]]>
