Extract

Silage effluent is a major contributor to farm pollution incidents in the United Kingdom. In 1987, silage effluent was responsible for 26% of all farm pollution cases reported, and 437. Of farm associated water pollution incidents that resulted in prosecution.

A practical solution to this problem could be to incorporate absorbent materials into the grass at ensiling. Several absorbent materials have been tested, some being based on fibrous bi-products. Of those tested, chopped barley straws proved the most effective (Offer an Al-Rwidah 1989) however this material lowered silage quality and also reduced the weight of grass that could be stored in a given silo by 78%. Molassed sugarbeet feed (MSBF), a feed high in digestible fibre which has been widely incorporated into ruminant diets as an energy source, was less absorbent but improved silage quality and reduced grass storage weight for a given silo by only 27%.
