Simple Selenium Supplementation
What are Seleni-Start and Seleni-Grass?
Seleni-Start and Seleni-Grass are grassland fertilisers enriched with granular Selenium specifically formulated to raise Selenium in pasture and forage to optimum levels for livestock health.
Why use Seleni-Start and Seleni-Grass?
- Selenium is essential for animal health
- Selenium deficiency is linked to infertility, retained placentas, poor LWG and a wide range of sub-clinical symptoms
- 90% of UK soils are deficient in Selenium
- Pasture and silage typically contains only 10-20% of the Selenium levels required by livestock
- Trials in the UK and Ireland have proved that Seleni-Start and Seleni-Grass can elevate and sustain Selenium levels in pasture, forage and animal bloods for optimal health and performance

Selenium – an essential livestock nutrient
1. Selenium and livestock:
Selenium is an essential nutrient for livestock health and performance. Selenium deficiency can lead to potentially serious clinical disorders and production loss:
✗ Retained placenta
✗ White muscle disease
✗ Ill-thrift, poor LWG and a range of auto-immune disorders
2. Selenium and grass:
- Although grass does not need Selenium, it does take it up from the soil
- 90% of UK soils are deficient in Selenium which is reflected in very low levels in grass
- Adding granular Selenium to fertiliser elevates the Selenium level in pasture and forage which is reflected in higher blood Selenium levels
- Higher levels of Selenium can be provided in the base diet throughout the year, enabling a reduction or elimination of other, more expensive forms of supplementation
Trials in the UK and Ireland have proved the efficacy of Seleni-Start and Seleni-Grass with improvements in fertility, less retained cleanings and higher LWG.
3. Selenium in fertilisers:
Applying Selenium in fertilisers such as Seleni-Start and Seleni-Grass:
- is simple and does not involve additional work
- is cost effective compared to other forms of supplementation (c. 2p per head per day)
- does not involve animal handling
- helps improve residual soil Selenium levels
