Abstract
Milo containing approximately 8.0% crude protein, fortified with vitamins, minerals and antibiotic, was inadequate as the sole source of protein for finishing pigs of 52- to 57-kg. initial weights. The addition of 0,25% lysine to such diets resulted in gains and gain-feed ratios equal to those of pigs fed a 12% crude protein corn-soybean meal diet.
With milo samples containing 0.20 or 0.28% lysine, maximum performance occurred when 0.24 and 0.16% of supplemental lysine, respectively, was added to the diet.
Finishing pigs receiving milo diets plus lysine produced carcasses having a higher percent of lean cuts, higher specific gravity values and greater loin-eye areas than animals receiving the milo control diet.
