Effects of feeding textured soy protein (TSP), in liquid form throught esophageal groove, or solid form throught concentrate meal, were studied in a 4 x 4 Latin-square change-over design, using four Holstein steers fitted with ruminal cannulas, averaging 100 kg live weight at the beginning of trial. Treatments consisted of increasing TSP levels in liquid form (0, 33, 66 and 100%) offered through nipple-pail, and decreasing levels in concentrate meal to keep the same amout of nitrogen in all diets.
