Document Summary
From 50 lbs to market weight (about 250 lbs) Access to all the feed they want, all the time. Grain-soybean meal based diets adequately fortified with minerals and vitamins. Avoid overcrowding - negative effects on pig performance. Amino acid requirements as a percentage of the diet decrease as pigs increase in weight. Estimated lysine requirement for pigs from 7 to. Until recently, feeding programs for growing-finishing pigs were based simply on the body weight of the pig based simply on the body weight of the pig. Today, we know that gender, lean growth potential, and health status also affect growing and finishing pigs. From about 100 lb to market weight, barrows grow faster and eat more feed than gilts. Gilts are more efficient (lower feed-to-grain ratio) and produce leaner carcasses than barrows. Protein requirements are associated with lean growth curve. High lean growth rate = higher amino acid requirements.
