Roles of Minerals

Question 1

minerals which are required in relatively
large amount and in most of cases they are used in the synthesis of structural tissues

Answer 1

macro elements (major elements)

Question 2

minerals required in trace
amounts and usually function as activators or as a component of enzyme system

Answer 2

Micro elements (Minor elements or trace elements)

Question 3

These are those minerals, which have been proved to have a metabolic role in the animal body.

Answer 3

Essential mineral elements

Question 4

calcium, phosphorus, magnesium, sodium, potassium, chlorine and sulphur are all example of what minerals?

Answer 4

macro elements (major elements)

Question 5

iron, copper, sodium, iodine, cobalt, zinc, are all minor elements, except?

Answer 5

sodium

Question 6

serve as the major structural elements of skeletal tissue

Answer 6

calcium and phosphorus

Question 7

What macro element is essential for skeletal formation, normal blood clotting,
rhythmic heart action, neuromuscular excitability, enzyme activation and permeability of membranes and acid base balance of body fluid and also in curdling of milk?

Answer 7

calcium

Question 8

It is a deficiency of calcium which symptoms occur in young growing animals. It includes misshapen bones, enlargement of joints, lameness and stiffness.

Answer 8

ricket

Question 9

In the adult animals, calcium deficiency results to bones becoming weak, porous and soft.

Answer 9

osteomalacia

Question 10

In osteomalacia the bones become weak, soft, and porous. Meanwhile this other deficiency is characterized by a decreased bone mass due to bone resorption being greater than bone formation.

Answer 10

osteoporosis

Question 11

shortly after parturition, high yielding cows may suffer from when serum calcium goes down with the result that there are muscular spasms and in extreme cases paralysis

Answer 11

milk fever

Question 12

Major portion of phosphorus in the animal body is distributed in?

Answer 12

bones

Question 13

plays an important role in the formation of bones and teeth along with
calcium

Answer 13

phosphorus

Question 14

What macro element is found in cells, excess of this salt in the body interferes with the absorption and metabolism of magnesium?

Answer 14

potassium

Question 15

deficiency result in slow growth, reduced feed and water intake, lowered feed efficiency, muscular weakness, nervous disorders, stiffness, emaciation, intracellular acidosis and degeneration of vital organs

Answer 15

potassium

Question 16

It is found in skin, subcutaneous tissues and gastric juices. Out of the total amount present in the body 80-85 percent is found in inorganic form while the rest 15 to 20 percent in organic form

Answer 16

chloride/chlorine

Question 17

required for the formation of hydrochloric acid of the gastric juice

Answer 17

chlorine

Question 18

This is a trace mineral which as a part of respiratory pigment and hemoglobin, it helps in the utilization of oxygen by the blood.

Answer 18

iron

Question 19

This is a trace mineral which as a part of respiratory pigment and hemoglobin, it helps in the utilization of oxygen by the blood.

Answer 19

iron

Question 20

If an animal has anemia, it is likely to be deficient in what trace mineral?

Answer 20

iron

Question 21

The disease is characterized by sudden death without any preliminary sign. In this fibrosis of myocardium takes place and macrocytic hypochromic type anemia appears.

Answer 21

falling disease

Question 22

This disease is caused by the deficiency of copper and cobalt in diet of cattle and sheep.

Answer 22

Coast disease (Neck ill, Lickin disease)

Question 23

Deficiency of this trace element is associated with goiter or enlargement of the thyroid gland. Condition in farm animals manifest itself as a swelling of the neck, ‘big neck’.

Answer 23

Iodine

Question 24

a dietary essential for ruminants because it is necessary for the synthesis of vitamin B12 by the gastrointestinal microbes

Answer 24

cobalt

Question 25

an important trace element for the proper growth of body and development of
hairs and keratinization of epithelial tissues

Answer 25

zinc

Question 26

Retarded growth, ‘Frizzled’ feather, parakeratosis and a bone
abnormality referred to as the ‘Swollen hock syndrome’

Answer 26

zinc deficiency

Question 27

This trace elements is crucial in reducing the incidence of dental caries. In very small amount the mineral is essential for the growth and proper development of the bones and teeth.

Answer 27

fluorine

Question 28

effect of deficiency is myopathy, exudative diathesis

Answer 28

selenium

Question 29

effect of deficiency is parakeratosis, poor growth,
depressed appetite

Answer 29

zinc

Question 30

effect of deficiency is retarded growth, skeletal
abnormality, ataxia

Answer 30

manganese

Question 31

effect of deficiency is goitre; hairless, weak or dead young

Answer 31

iodine

Question 32

effect of deficiency is pining (emaciation, anaemia, listlessness)

Answer 32

cobalt

Question 33

effect of deficiency is anemia, poor growth,
depigmentation of hair and wool, swayback

Answer 33

copper
