Ireland’s rich pastures provide a strong foundation for sheep dairy and beef production — but even the best grasslands can’t guarantee a balanced diet. Variations in soil type, fertilizer use, rainfall, and seasonal changes can leave gaps in essential trace minerals. These deficiencies often go unnoticed until fertility drops, milk yield declines, or animals start showing visible health problems.
Recognising early, subtle signs can help farmers take action before production losses occur — and that’s where consistent mineral supplementation becomes key.
Early Warning Signs to Watch For
1. Dull coat or faded hair colour
A shiny coat is a good indicator of health. If your cattle’s coats become rough, dull, or change colour (for example, black coats turning reddish), it could signal copper deficiency.
2. Slower weight gain and reduced appetite
When growth rates dip despite adequate feed, selenium or iodine deficiency might be limiting metabolism and energy use.
3. Poor fertility or retained placenta
Reproductive performance often reflects mineral balance. Low selenium or iodine levels can delay cycling and increase the risk of retained placenta after calving.
4. Lameness or poor hoof condition
Zinc deficiency can weaken hoof structure and slow healing, making cattle more prone to lameness.
5. Pica behaviour (licking stones or soil)
This unusual craving can indicate phosphorus or salt deficiency, especially when pasture quality changes.
Why Regular Monitoring Matters
Mineral deficiencies aren’t always visible until production is already affected. Routine forage or blood testing helps identify low trace elements before problems develop. Teagasc research shows that Irish grass mineral levels can fluctuate widely between seasons — meaning what works in spring may not hold up by autumn.
Prevention: Building a Balanced Supplementation Plan
Maintaining consistent mineral intake helps support:
-
Strong fertility and conception rates
- Smooth calving and recovery
- Healthy immune response and disease resistance
-
Improved coat condition and growth
