Trace mineral deficiencies in cattle: a review
The Canadian Veterinary Journal = La Revue Veterinaire Canadienne
|December 1, 1981
Summary
This review covers the biological roles of copper, zinc, and selenium in ruminant nutrition, exploring factors affecting trace mineral availability and symptoms of deficiencies.
Area of Science:
- Ruminant Nutrition
- Trace Mineral Metabolism
- Animal Science
Background:
- Copper, zinc, and selenium are essential trace minerals for ruminant health.
- Environmental and agricultural factors influence the availability of these minerals.
- Understanding these interactions is crucial for optimizing livestock production.
Purpose of the Study:
- To review the biological significance of copper, zinc, and selenium in ruminants.
- To examine the interplay between soil, climate, plants, and animals concerning trace mineral status.
- To outline clinical signs of copper, zinc, and selenium deficiencies in ruminants.
Main Methods:
- Literature review of scientific publications.
- Synthesis of information on trace mineral biology and nutrition.
- Compilation of clinical data on mineral deficiency symptoms.
Main Results:
- Detailed discussion of the physiological roles of copper, zinc, and selenium.
- Analysis of how environmental factors impact trace mineral uptake and status.
- Comprehensive description of deficiency symptoms, aiding in diagnosis.
Conclusions:
- Trace mineral nutrition is complex, influenced by multiple interacting factors.
- Accurate diagnosis and management of copper, zinc, and selenium deficiencies are vital for ruminant health and productivity.
- Further research into optimizing trace mineral supplementation strategies is warranted.
