Trace elements are essential minerals for the proper functioning of the animal body. Although they are only required in very small quantities, their physiological role is crucial. An imbalance, whether a deficiency or an excess, can lead to significant health problems. In this article, we will explore the biological functions of the main trace elements, their impact on animal health, and the importance of their dosage.
The main trace elements and their physiological roles
1. Zinc (Zn)
Zinc is essential for many biological functions :
- Growth and reproduction : it is involved in protein synthesis and cell division.
- Immune system : it plays a key role in immune response by helping white blood cells fight infections.
- Skin and coat health : it is fundamental for wound healing and maintaining healthy skin and coat.
Consequences of deficiency : growth delay, reduced fertility, skin lesions, weakened immune defenses.
2. Copper (Cu)
Copper is involved in several physiological processes :
- Red blood cell formation : it contributes to iron absorption and hemoglobin synthesis.
- Bone and nervous system development : it is essential for collagen formation and nerve myelination.
- Coat pigmentation : it influences hair and coat coloration.
Consequences of deficiency : anemia, neurological disorders, coat depigmentation.
3. Iron (Fe)
Iron is a vital trace element for :
- Oxygen transport : it is a key component of hemoglobin.
- Energy production : it participates in cellular metabolic processes.
- Development of young animals.
Consequences of deficiency : anemia, fatigue, growth delay.
4. Selenium (Se)
Selenium is a powerful antioxidant that :
- Protects cells from oxidative stress.
- Plays an important role in reproduction.
- Supports muscle and immune function.
Consequences of deficiency : myopathies, fertility disorders, reduced immunity.
5. Iodine (I)
Iodine is essential for the production of thyroid hormones, which regulate :
- Energy metabolism.
- Growth and development.
- Nervous system function.
Consequences of deficiency : hypothyroidism, growth delay, reproductive disorders.
Consequences of Trace Element Imbalances
Trace element imbalances may originate from :
- Dietary factors (deficiencies or excess related to feed composition)
- Environmental factors (soil quality, access to natural resources)
- Pathological factors (digestive disorders, metabolic diseases)
🚨 Accurate testing helps identify imbalances and adjust supplementation accordingly.
Deficiencies
- Weight loss and slowed growth
- Fertility problems and birthing complications
- Weakened immunity and recurring diseases
Excess
- Copper toxicity in certain species (sheep, dogs)
- Digestive and metabolic disorders
- Behavioral issues and chronic fatigue
Why Measure Trace Elements in Animals ?
Trace element analyses are essential to :
✅ Adjust nutrition: correct nutritional imbalances in the diet.
✅ Optimize health and performance: in livestock such as horses, pigs, and ruminants (cattle, sheep, goats, etc.), as well as domestic or wild birds and companion animals (dogs, cats).
✅ Prevent diseases: early detection helps avoid costly health conditions.
✅ Improve reproduction and growth.
💡 Trace element analysis allows precise adjustment of mineral intake for optimal health.
Methods for Trace Element Analysis
Samples can be collected from :
- Blood (plasma mineral measurement)
- Hair or mane/tail hair (long-term evaluation of mineral reserves)
- Urine or milk (complementary analyses depending on the species and context)
🔬 At IODOLAB, we use advanced techniques such as ICP-MS (Inductively Coupled Plasma Mass Spectrometry) to provide precise and reliable results.
Monitoring trace elements is an essential step in ensuring the health of animals, whether livestock or companion animals. Regular monitoring helps optimize nutrition, growth, and performance while preventing the onset of health disorders.
📢 IODOLAB supports you with cutting-edge analyses for accurate and tailored monitoring.
