Extract

Additives based on acids, have been widely used. Rather than encouraging latic acid fermentation, these act by partially, or completely, inhibiting microbial growth. With continuing concern over the safety aspects of these products, many farmers have tried inoculants, which encourage a lactic acid fermentation. However, in good silage making conditions, inoculants like other additives have not shown any consistent benefits in terms of silage fermentation or intakes. In poor silage making conditions, the industry still relies on tried and tested acid products to ensure adequate preservation of silage.

A new granular additive is now being evaluated. Its use is not to supress fermentation, but to supplement the natural fermentation by the addition of 1500 g/kg of sulphuric acid. This study was carried out to compare this additive with an untreated control and a positive control, formic acid.
