Abstract
Straw from which the hemicellulose has been removed is not digestible by ruminants. By application of the invention this material is rendered digestible. The process of the invention involves treatment of the hemicellulose-free straw with dioxane containing a small proportion of hydrochloric acid.
Claims3
A process for improving the digestibility of hemicellulose-free straw, which comprises
- a. soaking the hemicellulose-free straw for about one hour at room temperature in dioxane containing about 1 to 2% HCl, the amount of dioxane being enough to completely immerse the straw therein,
- b. removing dioxane and HCl from the so-treated straw by washing it with hot water, and
- c. drying the treated and washed straw.
