Individually fed steer calves (n=90) were used to evaluate different rendering procedures of pork meat and bone meal on protein quality as compared to soybean meal. Treatment proteins included an urea control, soybean meal, high-ash pork meat and bone meal, pork meat and bone meal control and non-enzymatically browned (NEB) pork meat and bone meal. High-ash meat and bone meal protein efficiency was higher than other treatments. However, the escape values determined by the ammonia release procedure were higher for NEB meat and bone meal, suggesting efficiency should have been improved relative to the control and high-ash meat and bone meal.
