Composition, digestibility and nutritive value of samples of grassland products

Abstract

The composition, digestibility coefficients and digestible nutrients of a large number of samples of fresh grass, silage, hay and artificially dried grass are tabulated. Curves have been prepared from these figures which enable the starch equivalent and protein equivalent to be obtained, by interpolation, from the value for crude protein determined by analysis. The method of calculating the starch equivalent of artificially dried grass from the data for digestibility and composition is discussed with particular reference to the fibre correction factor. It is considered that this should be the same as that used for the fresh grass prior to drying. A number of miscellaneous samples—mostly of home-grown foods—are included in the tables.
