Introduction • Several experiments have been conducted to evaluate replacing expensive specialty protein sources with crystalline amino acids in diets for 15 to 25 lb pigs. • Mixed results have been reported between p trials, indicating that further research should be done to determine the reason for the inconsistent response.
Step 1 Step 1 • Determine the lysine requirement of 15 to 25 lb y q pigs at the KSU Swine Teaching & Research Farm
