Background:

The inclusion of low digestibility mushroom lignocellulosic residues has become a significant part of recycling wastes. The enzymes produced are capable of transforming the substrate, improving it for further use.

Aim.

To conduct a review on the utilization of mushroom processing residues in animal nutrition.

Development:

The residues derived from mushroom processing is the substrate or compost that remained after mushroom harvesting. It has the required raw materials (hay, peels, etc.), as well as some added compound, such as urea or other sources of nitrogen. Besides, the action of mycelia on the compost may enhance its nutritional value. Edible mushrooms contain high-value bioactive compounds, and make an adequate source of prebiotics that have short-chain sugars. A fifth of all mushrooms remain on the bedding, providing nutritional and medicinal values. The nutritional changes were evaluated with techniques like the Weende scheme, and of in vitro, in situ, and in vivo determinations of digestibility.

Conclusions:

The results of this study showed that the residues from mushroom processing using low-quality sources (especially harvested rice stalks), may be used for animal nutrition, whose evaluation is necessary through the proper methods.
