Abstract
Three experiments were conducted with growing-finishing lambs to determine whether blood urea nitrogen was associated with protein intake. A close relationship was found (r = 0.986) indicating that this blood nitrogen constituent could be quantitated with protein intake. An equation for the determination of digestible protein required by lambs is also presented. Approximately 21 g of digestible protein were required for each 1000 kcal of digestible energy consumed.
