Abstract: Abstract：In this test, 40 F1 black goats （Nubia goat × Longlin goat）with weight of about 16 kg were randomly divided into five groups, including group I （60% concentrate plus 40% Bachiaria hybrid powder） as a control, group Ⅱ （60% concentrate plus 10% cassava stalk powder plus 30% Bachiaria hybrid powder）, group Ⅲ （60% concentrate plus 20% cassava stalk powder plus 20% Bachiaria hybrid powder） ,group IV （60% concentrate plus 30% cassava stalk powder plus I0% Bachiaria hybrid powder） and group V （60% concentrate plus 40% cassava stalk powder）, and test was carried out for 60 d. Covariance analysis was used to correct the difference of initial weight of goats tested, and the effects of using cassava stalk powder to fatten the housing goats were analyzed. The results showed that the average daily gain （ADG） was no significantly different among the five groups （P 〉 0.05）, while the average daily food intake （ADFI） of group I was significantly higher than that of group Ⅱ, group Ⅲ, group IV and ~ouo V （P〈0.05）. In a word. it is feasible to use cassava stalk nowder to fatten the housin~ ~oat~_
