Phase 3 nursery diet
The phase 3 diet is typically fed to pigs from 25 to 50 lb of body weight. During this phase, feed consumption is the greatest and feed cost is critical, accounting for more than 50% of the total feed cost in the nursery.
The phase 3 diet is typically based on grain and soybean meal with no inclusion of specialty protein sources and lactose. Fat is utilized by the pig to improve growth performance and can be included at 1 to 3% in the diet. Common sources of fat are choice white grease or beef tallow, but other good-quality sources can be used if economically justifiable.
