This study was conducted to investigate the optimal CP level in growing goat kids. Forty male goats were divided into four treatment groups fed diets containing CP 12, 14, 16, and 18% of concentrate feed, and rice straw, respectively. Results are summarized as follows. Average daily gain's (ADG) of groups fed diets with CP 14% and CP 18% were 84.0 and 83.0 g/d each, which were higher than group fed diets with CP 12% grown at 69.2 g of ADG (P<0.05). Daily feed intakes of concentrate and rice straw were 590 g and 45 g each and there was no difference found between treatments. The amounts of feed required for body weight gain(g) were similar in the range of 7.0 7.3 for groups fed diets with CP 14%, 16% or ～ 18%. But the group fed diets with CP 12% required somewhat more feed for gain at 8.8 g. Dressing percentage of groups fed diet with CP 12% was 61.7%, which was higher than groups fed diets with CP 14% or CP 18% (P<0.05) but similar to that fed diet with CP 16%. Meat percentage from goats fed diet with CP 16% was 51.7%, which were higher than goats fed diets with CP 12% or CP 14% (P<0.05). Fat deposition of CP 12% group was higher than the other groups (P<0.05). Percentage of bone weight averaged 17.0% without any difference among treatment groups. Shear force and cooking loss, which are physical properties of goat meats, were lower in CP 16% and CP 14% groups than the other two groups. Water holding capacity of goats meats from CP 16% was higher than those from CP 18% group (P<0.05). Results from panel test showed that juiciness of meats from CP 16% group was higher than those from CP 12% group (P<0.05). Meats from CP 16% also was tested to be more tender than meats from the other groups. Results from this work suggest that the optimum crude protein level in growing goat's concentrate is 14 16% and that increase above this level seems not to improve meat production.
