Hydrothermally processed starch urea mixtures employed in urea-containing liquid supplements were shown to improve N use through in vitro rumen fermentation. Starch sources used were potatoes and corn. The starch source was blended with feed-grade urea (45% N) and water in a specific starch source-urea ratio, then hydrothermally processed. H/sub 3/PO/sub 4/ and EtCO/sub 2/H were added to lower pH and to act as an antifungal agent, respectively. In vitro microbial protein synthesis showed the 1.63:1 potato-based supplement on an as-is basis had more protein synthesized than did either the 1.90:1 potato- or 1.83:1 corn-based liquid supplement. However, on a dry basis, the corn-based supplement had more protein synthesized than either of the potato-based supplements. Compared with a 1.83:1 corn-based supplement, a 1.83:1 potato product performed equally well or better, based on microbial protein synthesized.
