Urea, Corn Gluten Meal or Soybean Meal as Supplemental Crude Protein Sources for Feedlot Steers Limit-Fed High Energy Growing Diets

Urea, corn gluten meal and soybean meal were compared as supplemental crude protein sources for growing steers fed limited amounts of a high energy diet. Interactions between level of urea and natural protein source were not significant, indicating that source of natural protein did not influence urea utilization. Level of urea and source of natural protein did not affect average daily gain. These data indicate that up to 1% of diet dry matter as urea can be effectively utilized by limit-fed cattle
