Abstract: In order to discuss the influence of sodium humic acid added on feed for goat to the use of mineral element,60 adult guanzhong dairy goats were randomly divided into two groups,30 in each group.In test group,4 g sodium humic acid was provided for each goat every day.The ration of control group was not changed during test period.At the end of the feeding experiment,the mineral elements in the milk and dejection from the two groups were estimated.The result showed that the levels of P、Fe、Cu、Zn in milk from test group was lower than that of control group,the levels of Cu and Zn were only 53.57% and 38.07% as more as that of control group.The level of Ca、P、Fe、Cu、Zn in dejection from test group were 1.32,1.23,1.49,1.28 and 1.68 times as that of control group respectively.Thus it can be seen that the mineral elements was lost excessively and their utilization ratio was decreased by the odium humic acid added to feed for goats.
