Deficiency Symptoms |
| Vitamin A - Essential for normal growth and for the formation of strong bones, teeth, for normal vision and cell structure, for protecting the linings of the respiratory, digestive, and urinary tracts and for healthy skin. Reserves can be stored in the liver for a few months. Kids with coccidiosis have an increased vitamin A requirement because of impaired absorption. | Naturally taken in by grazing animals in the form of protovitamin and converted into vitamin A by the intestinal wall. Good pasture and fresh hay contains adequate quantities while old or weathered hay is a poor source. After 6 months of storage, all beta-carotene in hay has been destroyed. Colostrum is a very rich source of vitamin A if the doe is healthy at birthing time. |
|
| Vitamin B1 (thiamine) - This vitamin plays a vital role in the activities of various enzymes involved in the breakdown and utilization of carbohydrates and in the functioning of the nerves, muscles and the heart. Kids that do not yet have a fully developed rumen need a dietary source of B complex vitamins. B vitamins also should be added to the diet or administered by injection to sick animals and those with poor rumen function or marked change in diet. | Normally synthesized in adequate amounts by rumen microbes. |
|
|
Vitamin B12 –
Also known as Cyanocobalamine, a vitamin that plays a vital role in the
activities of several enzymes. It is important in the production of the
genetic material of cells (and thus in the growth and development), in the
production of red blood cells in bone marrow, in the utilization of folic
acid and carbohydrates in the diet, and in the functioning of the nervous
system.
|
Cobalt is essential for the production of vitamin B12 by micro-organisms in the rumen |
|
| Vitamin D – There are two main forms of vitamin D. D2 ( ergocalciferol) and D3 ( cholecalciferol). They play several vital roles in the body. The vitamin helps regulate the balance of calcium and phosphate, aids in the absorption of calcium and is essential for strong bones and teeth. Excess of vitamin D can cause problems. | D2 is made in the skin, induced by ultra-violet rays. It takes part in the absorption, deposition and excretion of calcium and phosphorus. D3 is found in liver oil from marine fishes. Colostrum is rich in vitamin D. If adults are on pasture or fed much sun-cured hay, their needs should be easily met. |
|
| Vitamin E - It is essential for normal cell structure, for maintaining the activities of certain enzymes and for the formation of red blood cells. It also protects the lungs and other tissues from damage by pollutants and help prevent red blood cells from being destroyed by poisons in the blood. Its main action is as an antioxidant; it stabilizes polyunsaturated fatty acids, vitamin A, and various hormones and enzymes. Vitamin E and selenium are closely interrelated | Present in colostrum, milk, hay and grasses. Older hay is very low in vitamin E. |

Deficiencies of various items can also cause abortions. For these we will list only the symptoms and suggest that you look at these topics in other sections where available. CALORIC DEFICIENCY
GENERAL NUTRITIONAL DEFICIENCIES:
HYPOPROGESTERONISM
IODINE DEFICIENCY
MANGANESE DEFICIENCY:
PROTEIN DEFICIENCY:
WHITE MUSCLE DISEASE:
Poisoning as a result of ingestion of chemicals. The exact signs as they relate to abortion or damage to the fetus are highly dependant on the specific time in the gestation process when the event takes place. NITRATE / NITRITE POISONING:
