Abstract

A feeding trial was conducted to evaluate performance and estimates of microbial CP (MCP) supply in high moisture corn finishing diets with corn bran addition and different sources of degradable protein. Corn bran increased intake throughout the feeding period but decreased performance after day 42. Microbial efficiency and MCP were unaffected by corn bran addition, but MCP increased with increasing urea level. Performance was increased for the first 42 days when SBM was fed relative to urea, but microbial efficiency and MCP were unaffected. Supplemental DIP level did not affect MCP estimates. Estimates of MCP from allantoin were low and variable but did reflect differences that could be explained with performance.
