Abstract

Four metabolism trials were conducted with steers to study the influence of 0, 1, 2 and 4% urea, 0, 5, 10 and 20% cane molasses, nitrogen energy and phosphorus source on nutrient digestibility and nitrogen balance. The inclusion of 1% urea, equivalent to 5% urea in a molasses mixture when fed as 20% of the total ration, improved (P < .05) the digestibility of crude fiber and slightly increased the digestibility of dry matter and energy. Adding 2 or 4% urea gave no further increase in digestibility. Crude protein digestibility was increased with each urea addition, but nitrogen retention was highest with 1% urea (P < .05). The digestibility of dry matter, energy and NFE was increased (P < .05) by including 5 or 10% molasses in the ration, and further improved by 20% molasses. Crude fiber digestibility was similar at the 5, 10 and 20% molasses, and higher (P < .05) than at the zero level. Replacing urea with soybean meal or molasses with corn had no significant effect on nutrient digestibility.
