Here is what Drs. Tim Loula, Paul Yeske and Ross Kiehne of the Swine Vet Center, St. Peter, MN, have to say about managing double-filled wean-to-finish buildings:

Getting Pigs Started – First Ten Days Are Critical

• Make sure there are enough mats for double-filled pigs to lie on. That usually means two 4 x 4’ (1.22 x 1.22 m) mats or two 4 x 6’ (1.22 x 1.8 m) mats.
• Provide ample heat above the mats. Drs. Loula, Yeske and Kiehne suggest tube heaters, brooder heaters or two heat lamps.
• Hand-feed on mats to help pigs get started until their social eating order is established.

Feeding

• Feeders must have enough feed spaces to handle double-filling. Watch pigs closely and check for noticeable signs that bellies are filled.
• Back off on hand-feeding after about three days. Pigs should be eating from the feeder by seven days after entering the barn. If there is a wide age range of pigs due to filling dates, make sure to hand-feed accordingly.

Ventilation

• Because of the heavy load of pigs during the first part of the feeding period, it is easy for rooms to be under-ventilated or too humid. Shoot for humidity levels of 50 to 70 percent and ventilation rates of 2 cfm/pig.

Adequate Water Source

• Small pigs and problem pigs benefit from additional water and nutrition source such as a bowl that latches to the floor. Producers often add antibiotics, electrolytes, vitamins and plasma.
• Cup waterers can be clamped open or left dripping to help small pigs find the water source.
• Styrofoam pieces can also be used in the nipple to hold it open until pigs find water source and knock it out.

Disease Prevention

• Wide slats can get dirty with manure buildup. Keep slats dry to avoid exposing pigs to high pathogen load.
• Sick pens should have a bowl system that can provide water mixed with feed to form a mash.
• Treat sick pigs immediately. Look for lameness, pigs that are off-feed and other signs of illness.
