摘    要: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.

关 键 词:均匀设计  酸化剂  系酸力  抑菌能力

Abstract: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 for-mulas, a regression equation was set and the optimum formula was determined with stepwise regression analysis method.Re-sults 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 im-proved with the uniform design method.
Keywords:pH  Uniform design  Acidifiers  pH  Acid-binding capacity  Bacteriostatic ability
