'Pithed frog' position in baby guinea pigs is due to deficiency of which vitamin?

  1. Vitamin E
  2. Vitamin A
  3. Vitamin K
  4. Vitamin C — Correct Answer
Explanation:
Correct Answer: Vitamin C

Vitamin C (L-Ascorbic acid) deficiency causes the 'Pithed frog' condition in baby guinea pigs — the animal lies prostrate, unable to move, resembling a pithed (killed) frog.

Why Guinea Pigs Are Affected

Guinea pigs (like humans) cannot synthesise Vitamin C because they lack the enzyme L-gulonolactone oxidase. Same deficiency exists in humans (causing scurvy), monkeys, and poultry.

Vitamin C Deficiency Diseases
  • Humans: Scurvy — bleeding gums, petechiae, impaired wound healing
  • Baby guinea pigs: Pithed frog position
Vitamin C Facts
  • Other name: Anti-stress vitamin
  • Precursor: Hexose sugar (glucose)
  • Synthesised from glucose in most animals via L-gulonolactone oxidase
  • Important for collagen synthesis (hence wound healing and bone formation)
