Popis:	Protein balance trials with four sheep were conducted with mixtures of a single variety of grass hay containing 4.36–14.46% CP (N × 6.25). The data were used to calculate the minimum urinary CP excretion and the biological value of the ingested CP. Minimum daily urinary CP excretion was 1.08 g BW−0.75. Biological value was calculated to be 0.70 at a dietary CP content of 6.79%. Key words: Biological value, protein, sheep, timothy, hay
