Summary

A digestibility trial was conducted to determine the effect of methionine addition to a grain-urea based supplement on the digestibility of mature prairie hay. Ad libitum hay supplemented with .I Ib supplemental crude protein from either a (1) soybean meal, (2) methionine + urea-grain, (3) sulfur + urea-grain or (4) urea-grain supplement was fed to 20 Hampshire ram lambs. Dry matter, neutral detergent fiber and acid detergent fiber disappearances tended to be higher with methionine or sulfur-urea supplements over urea alone. Diet digestibilities between soybean meal, - methionine and sulfur treatments were similar. Methionine increased apparent nitrogen digestibility of the diet compared to other treatments. Dry matter intake, urinary nitrogen excretion and nitrogen retention were not affected by supplementation. It appears that methionine and sulfur enhance utilization of mature prairie grass hay when added to a urea-grain based supplement.
