本研究旨在探讨复合酸化剂配方的研制方法。试验采用均匀设计方法，设计了2个类型的酸化剂：磷酸型（酸化剂A）和乳酸型（酸化剂B），每种酸化剂设置6种不同的配方，通过研究不同配方的2种酸化剂的饲料pH、系酸力以及抑菌能力，建立回归方程，并用逐步回归分析法确定2种酸化剂的最佳配方。结果表明，当酸化剂A中磷酸占30%、柠檬酸占20%、延胡索酸占20%、甲酸钙占5%时，酸化剂A对饲料pH、饲料系酸力以及有关细菌的抑制作用方面效果最佳；当酸化剂B中乳酸占40%、柠檬酸占20%、延胡索酸占20%时，综合效果最佳。结果提示，用均匀设计方法研制复合酸化剂的配方完全可行，而且可减少试验次数，提高试验效率。

The uniform design method was used to study the formula of compound acidifiers. Two types of acidifiers, i.e. phosphoric acid type (acidifier A) and lactic acid type (acidifier B), with 6 different formulas for each type were selected. Based on the pH of feed, acidbinding capacity and the bacteriostatic ability of the two types of acidifiers with different formulas, a regression equation was set and the optimum formula was determined with stepwise regression analysis method. Results indicated that the optimum effects occurred when the phosphoric acid, citric acid, fumaric acid and calcium formiate of acidifier A accounted for 30%, 20%, 20% and 5%, respectively, while the optimum effects occurred when the lactic acid, citric acid, and fumaric acid of acidifier B accounted for 40%, 20% and 20%, respectively. It was concluded that the study of acidifier formula with the uniform design method was feasible and the test efficiency of formula of acidifier study was improved with the uniform design method.
