采用实验室培养基和微生物菌剂对甲醛、溴硝丙二醇、泰乐菌素和匹马菌素作为青贮添加剂进行了模拟青贮试验。发酵受到33 mM甲醛、1.2 mM溴硝丙二醇和0.2 mM泰乐菌素的限制。匹马菌素发酵的影响不大，但0.3 mM的水平防止霉菌生长时，青贮饲料暴露于空气中。甲醛和溴硝丙二醇的抗菌作用，泰乐菌素的抗菌作用和匹马菌素的抗真菌作用支持在早期的工作中获得的结果与青贮饲料微生物的培养。然而，防止乳酸菌生长所需的浓度比纯培养试验高约4倍。然而，防止模拟青贮饲料发酵所需的甲醛和溴硝醇水平低于含有饲料的试管筒仓中所需的水平。
Formaldehyde, Bronopol, tylosin and pimaricin were tested as silage additives in simulated silage based on laboratory media and microbial inocula. Fermentation was restricted by 33 mM formaldehyde, 1.2 mM Bronopol and 0.2 mM tylosin. Pimaricin had little effect on fermentation but a level of 0.3 mM prevented mould growth when the silages were exposed to air. The antimicrobial effects of formaldehyde and Bronopol, the antibacterial effect of tylosin and the antimycotic effect of pimaricin support the results obtained in earlier work with cultures of silage microorganisms. The concentrations required to prevent growth of lactic acid bacteria were, however, about four times higher than in pure culture tests. The levels of formaldehyde and Bronopol required to prevent fermentation in the simulated silages are, however, less than in needed in the test-tube silos containing forage.
