Pigs can be susceptible to salt toxicity, also known as salt poisoning and water deprivation. Salt toxicity occurs more commonly when pigs don’t drink enough water over actually ingesting too much salt. The normal salt content in their feed can become toxic when pigs don’t have access to fresh water to drink. Early symptoms of salt toxicity include increased thirst, constipation, and extreme itching. As the pig’s condition worsens, the nervous system begins to be affected. The pig will act like it is in a drunken state and can become uncoordinated. They may act blind, deaf, refuse feed and water, display dog sitting, and have seizures. Death can occur within several hours to several days from the beginning of symptoms without fresh water. If salt toxicity is suspected, pigs need to be rehydrated slowly with water and electrolytes. Too much water too fast can shock the pig’s system. If severe symptoms have started, treatment is best done under the direction of a veterinarian. Pigs with nervous system symptoms should be placed in a darkened area with bedding to prevent injuries. 

Salt toxicity is very preventable in your Kunekune herd. Be sure to always have fresh, clean water available at all times. During warmer weather, be sure to keep water in the shade since pigs tend not to drink water that is hot. Water can be kept cool by freezing water jugs and putting it in the water source. If possible, conduct multiple water checks daily. Avoid salty foods or other farm animal feed with a higher salt content. Commercial dog and cat foods have a high salt content and should never be given to pigs. Lastly, it is vital to have a veterinarian that can treat your Kunekunes and assist you with any issues that arise.
