The preservation of feed for periods of underproduction is a universal problem. All farmers worldwide face the need of guaranteeing the feed for their animals over the year, and not only quantitatively but also qualitatively. A first differentiation in the techniques used for preserving feed is done by the presence or lack of oxygen. Grains and hay are mainly preserved aerobically with the addition of different kinds of preservatives. A classic example for an anaerobic preservation technique is ensiling.
Though ensiling will mainly be used to preserved voluminous feed, many other substrates including grains, by products like fish residues, wet distillery grains with solubles or WDGS, brewer's grains, etc., can also be ensiled.
Silage, haylage, baleage? What is the difference between them? Are silage inoculants able to improve their fermentation quality and/ or the aerobic stability? The purpose of this article is to provide tools for the necessary differentiation, as well as to show results in the use of silage inoculants for haylage... but, what is haylage?
