Vitamin A deficiency has been associated with slowed re-epithelisation, decreased collagen synthesis and stability and an increased susceptibility to infection. Vitamin C (ascorbic acid) is an essential cofactor during collagen biosynthesis. In scurvy, the collagen formed is unhydroxylated, relatively unstable and subject to collagenolysis.

It is generally characterized by a decreased concentration of calcium and phosphorus in the organic matrices of cartilage and bone. Vitamin A deficiency occurs most commonly due to a lack of vitamin A in the diet, or inhibition of absorption from the digestive tract. It is commonly seen in cattle and sheep in feedlots, and also those being fed high concentrate diets in the absence of green pasture, as is common during droughts. Topics in this Primefact include: Signs of ... Vitamin D deficiency has been found to be common in patients with Parkinson's disease, Alzheimer's disease, schizophrenia, depression, anxiety disorders, dementia, and older adults with cognitive decline.

Iron deficiency is the most common deficiency seen in dogs and piglets but occurs less commonly in horses, cats, and ruminants. Iron deficiency is rarely nutritional in origin—it most commonly occurs secondary to chronic blood loss.Young animals have minimal iron stores, and milk contains very little iron. Like people, guinea pigs lack the physical ability to manufacture their own vitamin C, and require an outside source of vitamin C in the form of vegetables and fruits. If a guinea pig does not get enough of this vitamin in its diet, its body's supply of vitamin C will disappear quickly, leaving it ...

Vitamin A deficiency The finding of combined deficiency of these Factors (Factors II, VII, IX, and X), but normal fibrinogen (not vitamin K-dependent) is the hallmark of vitamin K-dependent coagulopathy. Protein C is an additional vitamin K-dependent hemostatic protein with very short half-life whose levels are markedly decreased early in vitamin K deficiency states. The vitamin-K dependent inhibitors and coagulation factors are synthesized in the liver as “inactive” or non-functional precursors. They require modification with γ-carboxylation in order to be functionalized – this modification process requires vitamin K.

Experimental vitamin A deficiency has been extensively studied in dogs, with the initial studies of this fat-soluble vitamin deficiency being made in dogs in the 1920s (Mellanby, 1950). Vitamin A deficiency is usually confined to young animals, and advanced deficiency is always associated with cessation of growth or even weight loss. The major cause of vitamin A deficiency is a diet that includes few animal sources of pre-formed vitamin A. In addition, iron deficiency can negatively affect vitamin A uptake. Institutionalized children are at particular risk for vitamin A deficiency due to diets low in vitamin A-rich foods. Deficiency symptoms include loss of appetite, rough hair coat, and reduced feed efficiency. Swelling of the legs and brisket, especially after working the animals, is also a symptom of vitamin A deficiency. Best source is beta-carotene. The best source of this vitamin is beta-carotene, a pigment in green plants that animals convert to vitamin A.
