Identifying the False Nutritional Statement
Which of the following statement is NOT true:
- Copper & molybdenum act as antagonist
- Vitamin E & selenium act synergistically
- Alkali disease is caused by deficiency of selenium — Correct Answer
- Teartness is caused by toxicity of molybdenum
Explanation:
Correct Answer: Alkali disease is caused by DEFICIENCY of selenium (NOT true)
The statement "Alkali disease is caused by deficiency of selenium" is NOT TRUE. Alkali disease is actually caused by TOXICITY of selenium (chronic selenium poisoning), not deficiency.
Selenium — Toxicity vs. Deficiency Diseases
| Condition | Type | Diseases |
|---|---|---|
| Selenium TOXICITY | Acute | Blind staggers |
| Selenium TOXICITY | Chronic | Alkali disease, Degnala disease |
| Selenium DEFICIENCY | — | Ill thrift in lambs, Nutritional muscular dystrophy, Exudative diathesis |
Verification of the Other True Statements
- Copper & Molybdenum act as antagonists: TRUE — excess Mo interferes with Cu absorption
- Vitamin E & Selenium act synergistically: TRUE — both are antioxidants; each can partially replace the other
- Teartness is caused by toxicity of Molybdenum: TRUE — Teartness/Peat scour = Mo toxicity in cattle
Why Other Options Are Wrong
- Copper & molybdenum act as antagonist → TRUE statement; not the answer
- Vitamin E & selenium act synergistically → TRUE statement; not the answer
- Teartness caused by Mo toxicity → TRUE statement; not the answer
