Vit/Min Deficiency

Deficiency signs for certain vitamins/minerals in animals: ASCI 220, Cal Poly

QuestionAnswer
Vitamin A 1) night blindness 2) Reproductive failures 3)Xerophthalmia 4) increased respiratory and genitourinary tract infections 5) thickening and karatinzation of epidermis 6)skeletal lesions
Vitamin D Chronic: skeletal lesions Acute: tetany and related muscle and nervous disorders (hypocalcemia) Poultry: decreased egg production/hatchability Increased incidence of cancer, autoimmune disease, infections
Vitamin E -Nutritional Muscular Dystrophy - muscle degeneration from oxidative damage. muscle weakness, paralysis, death. -Compromised immune system defense -poultry: reproductive failure, crazy chick disease, edema
Vitamin K -Increased blood clotting time -- serious hemorrhaging/death -Osteoporosis -Atherosclerosis
Thiamin -Affects tissues with high metabolic rate -GIT problems (impaired digestion/absorption), anorexia, diarrhea -Muscle weakness, fatigue -nerves (incoordination, convlusions)
Riboflavin -Curled-toe paralysis in chicks: muscle weakness/paralysis -skin and eye lesions
Pantothenic Acid 1) lesions of nervous system 2) skin and hair problems (loss and graying of hair) 3) GIT degeneration = inflammation, diarrhea, vomiting
Vitamin C (ascorbic acid) Scurvy: swollen, bleeding gums; loose teeth; poor wound healing; weak bones; hemorrhaging --due to defective collagen synthesis and oxidative damage Compromised immune function
Choline Fatty livers Slipped-tendon perosis in avian species Incoordination (swine)
Calcium Chronic: Bone abnormalities (Rickets in young animals, osteomalacia in old) Acute: Tetany (paralysis) and death, "milk fever" Increased blood clotting time
Phosphorus Pica Impaired fertility in catle Bone abnormality
Magnesium Acute: vasodilation, loss of equilibrium, convulsions, tetany, death Chronic: bone demineralization GRASS TETANY
Cobalt Vit. B12 deficiency in ruminants (anemia, nervous system lesions, changes in GIT epithelial cells causing a malabsorption syndrome)
Zinc Severe dermatitis impaired wound healing Poor feather, hair, or wool development
Fluorine (F) Dentail cavities Osteoporosis Calcification of aorta
Iodine Goiter: enlargement of thyroid gland due to accumulation of thyroid proteins Young born weak, dead, or hairless
Selenium Nutritional muscular dystrophy Liver necrosis due to oxidative damage Exudative diathesis (edema) in chicks
Iron Iron-deficient anemia, decreased growth rate Deficiency is unlikely with animals on normal diets, except under pathological conditions or excess blood loss

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
