The inclusion of formic and propionic acids in the form of Bio-Add to the food of hens made no difference to the pH of the intestinal tract, but resulted in higher concentrations of these acids in the contents of the crop and gizzard. 2. Organic acids in the crop contents were bactericidal for Salmonella serotype Enteritidis PT4 in vitro, and also caused sub-lethal damage because fewer cells were recovered on selective salmonella media (brilliant green phenol red agar) than on non-selective media (nutrient agar). 3. Inclusion of Bio-Add in the food at 12g/kg may reduce the number of lactic acid-producing bacteria in the crop, and hence the amount of naturally produced organic acids.

以生物添加剂形式将甲酸和丙酸添加到母鸡食物中，对肠道pH值没有影响，但导致嗉囊和砂囊内容物中这些酸的浓度升高。2. 嗉囊内容物中的有机酸在体外对肠炎沙门氏菌血清型PT4具有杀菌作用，并且还造成亚致死损伤，因为在选择性沙门氏菌培养基（亮绿酚红琼脂）上回收的细胞比在非选择性培养基（营养琼脂）上少。3. 以12克/千克的量将生物添加剂添加到食物中可能会减少嗉囊中产生乳酸的细菌数量，从而减少天然产生的有机酸量。
