Incorrect Statement About Minerals and Vitamins

Correct Answer: (c) is FALSE

Alkali disease is caused by selenium TOXICITY (chronic poisoning), NOT deficiency.

Correct Facts

• (a) TRUE: Cu and Mo are antagonists — high Mo forms thiomolybdate complex, reducing Cu absorption. This causes 'secondary copper deficiency' (Teartness).
• (b) TRUE: Vitamin E and Se act synergistically — both protect against lipid peroxidation by different mechanisms.
• (d) TRUE: Teartness (Peat scour) = Mo toxicity in cattle — liquid diarrhoea with gas bubbles on Mo-rich pastures.

Selenium Diseases

• Toxicity: Blind staggers (acute), Alkali disease (chronic), Degnala disease (chronic)
• Deficiency: White muscle disease, Exudative diathesis, Ill thrift
