A feeding trial was conducted at Adami Tulu Research Center to assess the effect of level of substitution of lablab for concentrate on the growth rate of goats. Thirty indigenous male goats, aged 15-18 months, were divided into five groups and randomly allocated to the treatments: grazing (G)G + 250 g concentrate (Conc.)G + 125 g Conc. + 280 g lablab hay (La.)G + 60 g Conc. + 420 g La. and G + 560 g La. Concentrate and lablab intake were recorded daily and body weight weekly. Generally total supplement consumed by the goats reduced from 250 g/h to 167 g/h as more concentrate was substituted by more lablab hay. The intake of lablab (p0.05) increased from 98.5 to 167 g/d as the concentrate was reduced from 125 g/d to zero. The feed efficiency observed by supplementing grazing goats with lablab hay (8.9 g feed intake/m gain) was (p0.05) better than that supplemented with concentrate (12.5 g feed 1/g gain). All concentrate and/or lablab supplemented groups gained more than the control (grazing) animals. The difference in weight grain between those supplemented with concentrate and lablab was not significant. The weight gain obtained by supplementing with lablab was 90.7% of the gain obtained by supplementing concentrate. This indicates that lablab hay can partly substitute for concentrate.
