Toxicity Syndromes
Blind stagger, alkali disease, and degnala disease are caused due to the toxicity of:
- Selenium — Correct Answer
- Copper
- Manganese
- Zinc
Explanation:
Correct Answer: Selenium
All three conditions — Blind staggers, Alkali disease, and Degnala disease — are manifestations of selenium toxicity at different levels and durations of exposure.
Selenium Toxicity Syndromes
| Condition | Type | Characteristics |
|---|---|---|
| Blind staggers | Acute toxicity | Blindness, staggering, respiratory failure |
| Alkali disease | Chronic toxicity | Loss of hair/wool, hoof deformities, general ill thrift |
| Degnala disease | Chronic toxicity | Dry gangrene of face, tail & hooves; mainly in Punjab & Haryana |
Selenium — Both Sides
| Deficiency Diseases | Toxicity Diseases |
|---|---|
| Ill thrift in lambs | Blind staggers (acute) |
| Nutritional muscular dystrophy (White muscle disease) | Alkali disease (chronic) |
| Exudative diathesis in chicks | Degnala disease (chronic) |
Key Facts
- Selenium-containing enzyme: Glutathione peroxidase
- Selenium and Vitamin E show a synergistic effect
- Selenium toxicity → excess seleniferous plants in seleniferous soils (Punjab, Haryana)
Why Other Options Are Wrong
- Copper → toxicity causes Jaundice, haemolysis in sheep; not blind staggers or Degnala
- Manganese → toxicity causes skeletal deformities; not these three syndromes
- Zinc → toxicity causes interference with Cu/Fe absorption; not blind staggers or alkali disease
