Treatment comparisons in grazing trials using the animal as experimental unit
Published online by Cambridge University Press: 27 March 2009
Summary
Although it is not always valid to regard ‘within herd variation’ as a true measure of experimental error there are occasions when this may be the only feasible measurement. The effect is considered of regarding the animal as the experimental unit on the estimation of the ratio of production of two treatments and an approximate variance for the ratio is obtained. The conditions under which the approximation is valid are considered.
