Abstract: Twelve fattening Hainan Black goats at the age of 4 month were used to Study. A 4×4 Latin square experiment design was conducted to study the Effects of Different Four Diets on Blood Biochemical Indexs for Hainan Black Goats of stall-feeding Hainan Black goats fed the four different diets based on recommendation of nutrients requirements of Keral(1982). The results were as follows：The concentration of TP and ALB in diet 2 was significant difference (P<0.05) between diet 1 and diet 3,4；The concentration of UREA in diet 2 was highest,and significant difference (P<0.05) between diet 2 and diet4；The concentration of GLU in diet 2 was significant difference (P<0.05) between diet 1 and diet 4，there was no significant difference (P<0.05) between diet 2 and diet3；The concentration of TG and TC tended to increase, The concentration of AST,ALT and GLB were no significant difference (P<0.05).
