Common Diseases of Swine Associated with Nutrition

Abortion. This may be due to insufficient energy, the presence of fungal toxins or deficiency in iron.

Anaemia and/or haemorrhage can be due to aflatoxin, the presence of anticoagulants in feeds, deficiency in copper, iron or protein. Vitamin E and selenium deficiency may also be a factor for gastric ulcers.

Bone fracture, malformed bones, and lameness can be due to deficiency in any of the following: calcium, magnesium, manganese, nicotinamide, phosphorus or the vitamins A, D3, or E.

Diarrhea and colitis can be due to excess protein, high levels of wheat, or increase level of iron, potassium and magnesium.

Haemorrhages can be attributed to vitamin K deficiency.

Nervous symptoms, incoordination, or lameness may be due to deficiency in biotin, calcium, copper, magnesium, manganese, pantothenic acid, phosphorus, water or any of the following vitamins: A, B6, D3, or E.

Poor growth or poor appetite is a complex condition. All aspects of nutrition must be reviewed, especially the energy and the amino acids (lysine, arginine, histidine, isoleucine, methionine, cystine, threonine, tryptophan). The digestibility of the feeds or its components may also be a factor. Iron, zinc, magnesium, phosphorus, potassium and salt levels should also be checked as with the level of the following vitamins--- A, B6, B12, D3, choline, riboflavin, pantothenic acid and niacin. Water is also a big factor for growth and appetite.

Poor litter size may be due to insufficiency in choline, energy, folic acid, lysine, essential amino acids or vitamin E.

Reproductive failure might be due to deficiency in choline, energy, folic acid, iodine, lysine, manganese, essential amino acids, riboflavin or vitamin B12 and E.

Respiratory diseases may be exacerbated if there is deficiency in energy, protein or vitamin E.

Skin lesions may be due to deficiency in iron essential fatty acids, such as linoleic acid, nicotinamide, potassium, riboflavin, salt or commonly zinc.

Sudden deaths may be associated with deficiency in selenium, thiamine, vitamin E or to deficiency in water. Deficiency in water may cause salt poisoning.
