When choosing your pigs diet, these essential vitamins and minerals that also need to be factored in and/or considered. Because most average pig owners do not have a nutrition degree, we recommend that a manufactured pig feed be the main part of the diet so that vitamin or mineral deficiencies aren’t an issue for you and your pig. Can your pig have an all-natural diet? Sure…but you will need to be sure the diet is balanced and includes all the essentials being represented in the right amounts. Some of the deficiencies take some time to show up, some will show up right away, but this is something that will be ever changing and you can’t take part of an all-natural diet and apply it when you want. This must be done with consistency or the diet will not be balanced and you will be risking the health of your pig. If you are feeding a pelleted diet, this will likely not affect you, but if you are feeding an all natural diet, these are things you need to consider when deciding what you will feed your pig.
Pigs are mostly omnivores, which means they eat meat as well as plants and they have a high requirement for minerals, which is not surprising considering the time, spent digging and the amount of earth that may get swallowed. Because omnivores do not eat much herbage, they do not need ruminants like cattle and sheep. The main type of digestion in the pig is enzymatic and takes place in the stomach and small intestines, The salvia of omnivores contain an amylase enzyme so digestion begins as soon as food enters the mouth. Because bacteria only plays small role in a pigs digestion, its food must always consist largely od starch, sugar, fat and protein of a high biological standard that can be rendered soluble by the enzymes secreted in the stomach and intestines. Because of the small amount of vitamin synthesis that takes place in omnivores, it s essential to receive most of the vitamins required in the food. With animal vitamin and mineral supplementation, the golden rule is to have your soil tested to see what the deficiencies are in the soil. If your animals are living on what you are producing on your land, they will have the same deficiencies as the land.
If you notice that your pig is standing there looking at you and licking their lips, they could have a protein deficiency, you may want to think about supplementing with fish or meat meal, whey or cod liver oil, etc.
In a book I am reading, Farming naturally and organic animal care by Pat Colby, she says soybean meal can deplete iodine. She goes on to say that after 20 years of conventional farming, large amounts of seaweed meal, extra copper and zinc as well as dolomite are needed to keep pigs healthy. She went on further to say that whatever diet was fed to pigs, they would benefit from the following additives:
Dolomite: Teaspoon per head daily.
Seaweed: seaweed products of some kind.
Sulphur: A teaspoon per head daily.
Cod Liver Oil: A teaspoon at least once a week. If the pigs are totally free range, she suggested a salt lick similar to those given to cattle. (This would need to be used with the strictest of supervision) Sulphur in the diet should stop skin problems or it could be sued externally as a paste mixed with cooking oil.
Fat deficiency: Signs are hair loss and scaly flaky skin, dermatitis, areas of skin necrosis on the neck and shoulders and an unthrifty appearance in growing pigs. A level of 1-1.5% of fat seems ample to supply the essential fatty acids.

Enlisting the help of someone with a nutrition degree, someone with years of experience or even one of the pig feed manufacturer's nutritionalists can help you to be sure that your pig is getting what he or she needs to live a long healthy, happy life. Not providing the right amount of feed or the right amount of essential nutrients can lead to serious medical conditions that can claim the life of your pig well before his time. Click here to visit our nutrition section and click here to see what healthy versus unhealthy pigs look like. Don't focus so much on the weight of your pig, but look more towards the shape and size. That should be your biggest factor in determining the amounts of feed and types of foods you are feeding your pig.
