Note: Target levels represent naturally fermented silages or silages treated with fermentation aids such as microbial inoculants and/or enzymes.
*Forages inoculated with Lactobacillus buchneri products may result in higher than normal concentrations of acetic acid. Research shows the increased levels do not result in poor fermentations or negative effects on animal intake.
** 1,2- Propanediol is typically <0.25% but can be as high as 3.0% in silages inoculated with Lactobacillus buchneri.
