Fines tend to build up, moisture collects, and excess feed deteriorates in quality. Some feeders have limited adjustment ranges. This adjustment should improve rate of gain, compared to limited feed or too much feed in the feeder bottom. Less time and labor is needed at this setting. Don't restrict flow too much.
Low consumption can be more expensive than a moderate waste.
Inadequate ventilation or poor air quality may reduce feed intake and gains. Tail biting, fighting and other social vices may erupt and cause increased health risks. Water is one of the most important nutrients required by swine. Environmental temperatures can increase water intake up to twice the norm. Nipple waterers provide cleaner water than cup or bowl types and nipples may waste less water.
