#  Are Trace Element Deficiencies Holding Back Your Weaned Calves?

Once calves begin grazing and developing into functional ruminants, their demand for key trace elements increases significantly. Deficiencies in **copper, selenium, cobalt and iodine** can have a major impact on performance, often before obvious clinical signs appear.

Affected calves may show:

- Reduced daily liveweight gain
- Poor thrive and reduced feed efficiency
- Increased susceptibility to pneumonia and other diseases
- Dull coats and poor overall condition
- Delayed development and reduced future productivity

**Copper** plays a vital role in growth, immunity and enzyme function, while **selenium** supports muscle development and disease resistance. **Cobalt** is essential for vitamin B12 production in the rumen, helping convert feed into energy, and **iodine** is critical for normal metabolic function and growth.

Subclinical deficiencies are particularly costly, as calves may appear healthy while failing to reach their growth potential. As grazing seasons progress, forage mineral levels can vary considerably, increasing the risk of deficiencies on some farms.

**Top Tip:** If calf performance is below expectations, consider trace element status as part of your investigation. Early identification and appropriate supplementation can help maintain growth rates, support immunity and maximise lifetime productivity.
