*Install at least 2 nipples per pen. Locate nipples 14" apart for nursery pigs, and 24" for larger pigs. The distance can be reduced somewhat if the nipples are angled away from each other.

There is a close relationship between water intake and the amount of feed consumed. Water is a very important ingredient in the digestion process. Improper drinker adjustment can restrict water intake. Restricted water reduces feed intake-this in turn leads to poorer gain, and often weight loss.

Flush pans are available on some models of elevated crate stands and nursery decks. Each 1,000 lbs. of animal weight produces approximately 10 gallons of waste (liquid + solids) per day. This data will be useful in determining the amount of manure storage or holding capacity you will need. Normally, flush pans will need to be flushed every 4-7 days. It is always advisable to add approximately 5 gallons of water to each pen (immediately after flushing) to help reduce the ammonia odor buildup in your unit.

A low-quality feeder will not last long in a confinement hog house, as the moisture level near the floor will speed corrosion. When purchasing a feeder, look for heavy gauge 304 stainless steel models, with a workable agitator system. Wood feeders with 304 stainless steel lined trough areas are also very durable. Ease of adjustment in a feeder is as important as durability. If a feeder cannot be easily adjusted to prevent feed waste, it can easily cost its owner many times its replacement cost. With feed costing up to 40% of the producer's expenses, it makes sense to keep feed wastage to an absolute minimum.

*The calf feeder was originally designed for Dairy Beef ranging from 200-700 lbs. in weight. However, it may also be used as a calf creep feeder but the producer must furnish his own creep area.
