The Effects of Dietary Energy Density And Lysine:Calorie Ratio On The Growth Performance of The 20 to 55 LB Pig

Kansas State University Swine Research. A total of 336 barrows (initially 21.8 lb and 31 2 d of age) was used to evaluate the results of increasing levels of choice white grease and lysine:calorie ratio on pig performance. Increasing levels of both choice white grease and lysine:calorie ratio improved the growth rate and efficiency of pigs fed from 20 to 55 lb.
