To determine the effect of various amounts of ruminally undegradable protein in the diets of lactating cows fed steam-flaked sorghum, 24 Holstein cows (90 +/- 50 d in milk) were assigned to three treatments: 0.8% urea, 6% soybean meal, or 5% fish meal. Respective percentages of ruminally undegradabl...
