Ruminant Sensitive to Cobalt and Copper
Ruminant which is most prone to cobalt deficiency & copper toxicity:
- Sheep — Correct Answer
- Goat
- Cattle
- Buffalo
Explanation:
Correct Answer: Sheep
Sheep have a uniquely sensitive mineral metabolism — they accumulate copper rapidly in the liver (highly susceptible to copper toxicity) and simultaneously are highly susceptible to cobalt deficiency, which impairs microbial synthesis of Vitamin B₁₂ in the rumen.
Mineral Sensitivity — Species-Specific Notes
| Species | Most Susceptible to | Least Susceptible to |
|---|---|---|
| Sheep | Cu toxicity & Co deficiency | P deficiency (selective grazing) |
| Horse | — | Gossypol poisoning (resistant) |
| Pig (2–4 weeks) | Iron deficiency anemia (Thumps) | — |
Copper & Cobalt Deficiency Diseases
| Mineral | Disease | Signs |
|---|---|---|
| Cu deficiency | Steely/Stringy wool (Merino sheep); Swayback/Enzootic neonatal ataxia; Falling disease in cattle; Salt sickness | Demyelination of CNS in lambs (Swayback) |
| Co deficiency | Enzootic marasmus/Pine/Wasting disease; Cattle coast disease | Loss of condition; anemia |
