Relation between Chemical Composition and Nutritive Value of Uganda Grasses

IN the various regression equations which have been published the relation between the percentage of crude fibre and the digestibility of organic matter was used 1–3 . Walker and Hepburn 3 used the percentages of crude fibre and crude protein to calculate the digestibility of crude protein, while Watson and Ferguson 4 calculated protein equivalent by using crude protein only. Glover, Duthie and French 5 also used percentage crude protein only, although this was later modified by Glover and French 6 for cases where there was an abnormal ratio of crude fibre to crude protein by proposing an equation using both crude fibre and crude protein. Watson and Ferguson 4 used the percentages of crude fibre and crude protein in their equation for the calculation of starch equivalent, while Mitchell 7 and Hallsworth 2 used crude fibre only.
