This cost is partially offset by the lack of downtime associated with nursery pig movement and facility cleanup in wean-to-finish facilities. ![]() Nurseries have a lower cost/pig space and are utilized very intensively compared to wean-to-finish facilities in which pig density increases the cost/pig space. Pig flow and labor are key issues in the decision to build wean-to-finish versus nursery and grow-finish facilities. Pig age shouldn't vary more than two weeks in room under seven days range is ideal. Pig flow also dictates pigs/room/ facility/site. The expense of multiple buildings versus a single building with multiple rooms has meant AIAO is often practiced by depopulating rooms within a facility, a less desirable practice than depopulating facilities within a site. But for many producers, labor and siting issues dictate multi-age facilities at one site. Any facility design that fails to plan for AIAO pig flow severely compromises long-term health in a production system.ĪIAO by site remains the ideal. Standard All-in, all-out has become the management standard for nurseries and grow-finish facilities. now weights are more than 60 lb.Īll these changes reinforce the adaptability of the weaned pig and its ability to perform well, provided basic food and shelter needs are met. Pigs used to leave the nursery at 40-45 lb. Today nurseries are designed for 2- to 3-week-old pigs. Late-’70s nurseries were sized for 4- to 6-week-old pigs. In the past two decades, the industry has “discovered” decks, both single and multi-tiered, woven wire flooring, plastic flooring, small-group housing, large-group housing, zone heating, room heating and wean-to-finish barns.Īt the time, all these innovations were thought to be the best available technology to meet the unique housing needs of the newly weaned pig.Īs these new discoveries were applied, weaning ages were declining. While grow-finish and sow gestation facilities have undergone tremendous change in the past 20 years, these changes pale in comparison to those made in nursery buildings. ![]()
