Evaluating Variable Feed Energy Levels for Grow-Finish Pigs

Purdue University 2000 Swine Research Report. Todays swine genetics have lower feed intakes and higher lean accretion rates than pigs did even 5 to 10 years ago. These changes in pig performance require the evaluation of energy density of the diet at various grow-finish body weights to maximize growth performance. With lysine levels remaining constant, the varying levels of energy will also allow the evaluation of lysine to calorie ratios to achieve optimal growth rates. These ratios could then be applied to different energy and lysine levels to optimize nutrient utilization efficiency and pig growth rates.
