High feed pices the past few years have stimulated interest in adding fat to swine rations in an attempt to increase feed efficiency and improve rate of gain. Research has shown that, to get maximum utilization of added energy, protein levels in the diet also must be increased to maintain the calorie to protein ratio. In normal corn-soybean meal rations, lysine has been shown to be the first limiting amino acid. the experiment reported here was conducted to determine the lysine levels necessary in diets with and without fat and their effect on feed consumption, feed efficiency and rate of gain.
