This work was carried out on male Zaraibi goats to investigate the effect of using Teosinte forage in two roughage : concentrate (R/C) ratio (40:60 and 60:40) on growth performance, feed conversion and some blood constituents as well as economical efficiency. Eighteen male Zaraibi goats were divided into three equal groups (BH-40G, T-40G and T-60G) and fed according to NRC (1981) allowances: BH-40G fed 40 berseem hay (BH) : 60 concentrate feed mixture (CFM), T-40G received 40 Teosinte : 60 CFM and T-60G nourished 60 Teosinte : 40 CFM.
The data indicated that the digestibility of most nutrients of T-40G was significantly higher compared with BH-40G and T-60G. Thus, the TD*9N and DCP values were significantly better with T-40G (69.06 and 10.25, respectively) than BH-40G (65.27 and 10.05, respectively). The lowest values (P<0.05) of TDN (61.40) and DCP (8.51) were recorded with T-60G. Daily body gain (DBG) was improved with BH-40G and T-40G by 10.93 and 18.79 %, respectively compared with T-60G. Moreover, the DBG was increased by 9.68 % in T-40G than BH-40G. The feed conversion efficiency based on DM was better with T-40G followed BH-40G and lastly T-60G. The same trend was observed with feed conversion based on TDN and recorded 10.20, 9.76 and 10.50 for BH-40G, T-40G and T-60G, respectively. Using Teosinte forage in goat rations reduced feed cost/kg body weight gain from 13.93 LE in BH-40G to 11.90 and 11.72 LE in T-40G and T-60G, respectively. Therefore, the economic efficiency was higher with T-40G (1.68) and T-60G (1.71) compared with BH-40G (1.43). The economic efficiency was improved with the two Teosinte rations (T-40G and T-60G) by 17.5 and 19.6%, respectively compared with BH-40G (BH ration). Accordingly, feeding Teosinte at 40% instead of clover hay + 60 CFM level has better impact on growing kids either for growth rate or feed conversion efficiency and economic values.
