Use of new verity of hybrid El-Ryanah x El-Shamia maize as a new type of silage and has many attention due to their high protein efficiency, relatively high digestible energy and total digestible nutrients. Thus, the objective of this study was to evaluate feed intake, growth performance, nutrients digestibility and economic efficiency in growing kids zaribi goats. Twenty four growing zaribi kids were selected from the herd with nearly similar live body weight 13.67 kg and age 4 months old . Animals were divided into three groups (n=8 in each).All kids groups were housed in separated pens under similar environmental condition. All animals were nourished tested diet consisted of concentrate feed mixture (CFM) to cover 50% of protein requirements recommended by NRC (1989).Besides ad libitum supplement rations, where silage made of 100 % berseem (BS) offered to group1(T₁) as control ,silage made of 100% hybrid Raianah maize silage (HRMS) to group 2 (T₂) and silage made of 50 % berseem + 50 % hybrid Raianah maize (HRMBS) to group 3 (T₃). Feeding trails lasted for 180 days .The obtained results showed that T₁ ration (100% berseem silage) had higher NDF , ADF and ADL than those of T₂ , T₃ rations (100% hybrid corn silage).Moreover, the supplementing of hybrid maize as silage to basal diet had contributed to a reduction giber fraction and an increase of Metabolizable energy particularly with T₂  ration .Hybrid corn silage alone ((T₂) was higher of CP, NFE and NFC (14.89, 56.42 and 41.84 respectively), than T₁ (14.67, 51.63 and 41.58 respectively) and T₃ ( 14.03, 52.23 and 40.60 respectively).On the other side T₂ was lower of CF ,EE and Ash (17.02, 2.54 and 9.13) in comparison of T₁ ( 21.45,2.94 and 9.31) and T₃.( 14.03, 2.79 and 10.17 respectively) .In addition to metabolisable energy(ME) recorded the highest value with T₃ ration (10.01) followed by T₂ (9.93) ration and the lowest value had detected with T₁ ration ( 9.43).Growth rate and  daily body weight gain of kids fed experimental diets were recorded average daily gain values ( 146,154 and 167 g/h/d ) for T1, T2 and T3 respectively. Advantages percentage of total body weight of the experimental groups as found to be 3.39 % and 1.27 % for animal fed T2 and T3 ration compared to the control group (T1).Also, daily dry matter intake increased with T1 ration (1415) and T3 ration (1397) than those of the T2 ration (1367 g). Meanwhile , feed conversion was significantly among treatments (T1 , T2 and T3) , being (9.69 , 8.88 and 8.37 respectively) .Moreover, TDN of T1 ration  (60.68%) ,T2 ( 64.65 %) and T3 ( 63.45%) being DCP as same trend and the values were (9.79 %,10.03% and 9.56%) for T1,T2 and T3  respectively  with significant (p>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 T_{1 ,} T_{2 .} 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 )  .
