Chickens that have low salt rations may lose weight. In addition, there may be an increase in pecking behavior, feather eating and general flock nervousness. They may also show signs of reduction of egg production and egg size.
Symptoms of salt deprivation in dairy cattle include licking wood and eating soil or sweat. Symptoms occur within 2-3 weeks of deprivation. Water consumption will become excessive and urine output will greatly increase. Also, if there are several weeks of deprivation, appetite will begin to decline and weight loss will occur, and the animal may also develop a rough coat. In a high-producing cow, the breakdown can be sudden and death can occur.
