Effect of Dietary Energy Density and Lysine:Calorie Ratio on the Growth Performance of Growing Pigs and Subsequent Finishing Performance
Kansas State University Swine Research. One hundred twenty crossbred gilts were used in a growth trial to evaluate the effects of increasing dietary energy density and calorie ratio on growing pig growth performance and subsequent finishing perfor- mance. Feeding 3% choice white grease and 3.45 g lysine:Mcal ME maximized growth performance of growing gilts. Choice white grease additions and increasing lysine:calorie ratio during growing (65 to 160 lb) did not affect carcass backfat or loin depth at 235 lb.
