Studies on botanical proportions and nutritive value of varieties of cereal straws and the ability of sheep to select the botanical part with the greatest value

Abstract
Recent work has shown a great variability in the nutritive value of different cereal straws. Tuah et al (1986) examined a number of cereal varieties including barley, oats, wheat and triticale. Ramanzin et al. (1986) examined the extent to which these effects could be explained by differences in leaf:stem ratio and that the nutritive value of leaves were far greater value than straw.
