The present invention provides a silage composition supplemented with endo-xylanase activity. According to the present invention the addition of endo-, xylanase to fodder produces a silage having a significant increase in the amount of water soluble carbohydrates for use by lactic acid bacteria or as nutrients for the animal ingesting the silage; and increased fermentative production of lactic acid and acetic acid by lactic acid bacteria and the consequent lowering of pH which serves to preserve the silage composition. Also provided are silage compositions which further contain an inoculum of a lactic acid bacteria.

Why it's free to use
- Filed July 24, 1991. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 24, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 24, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
