This study was conducted to investigate the growth performance, of fattening kids fed berseem silage alone or mixed with either , barley, hybrid Napier grass or Rod grass .Thirty-two growing Zaraibi kids of four months age and averaged 13.19 kg live body weight were used to this study.The animals were distributed on four feeding treatments (8 heads each),were used in this study .The experiment included two stages. The first stage represents a growing period 140 days ,during which the kids were fed concentrate feed mixture (CFM) to cover 50 % of protein requirements recommended by NRC(1989).In addition to ad libitum silage supplement, where (100 % berseem silage) was offered to group1(G1),(50 % berseem+50 %barley silage) to group 2 (G2),( 50% berseem+50% hybrid Napier grass silage) to group 3(G3) and (50% berseem+50% Rod grass silage) to group 4 (G4).Second stage the ( finishing period 60 days) all experimental groups were fed 60% concentrate feed mixture (CFM)+ 20% berseem hay+20% rice straw. The results showed that , during the first stage ( growing period of 140 days) the substitution of mixture of Rod grass x berseem silage G4 ) and hybrid Napeir grass x berseem silage(G3) significantly (p > 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 .
