SeleniGrass

What are Selenistart and Selenigrass?

Selenistart and Selenigrass are grassland fertilisers enriched with granular selenium specifically formulated to raise selenium in pasture and forage to optimum levels for livestock health.

 

Why Use SeleniStart and SeleniGrass?

  • 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 proven that Selenistart and Selenigrass can elevate and sustain selenium levels in pasture, forage and animal bloods for optimal health and performance.

Trials in the UK and Ireland have proved the efficacy of Selenistart and Selenigrass with improvements in fertility, less retained cleanings and higher LWG.

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:

  • Infertility
  • 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.


3. Selenium in fertilisers:

Applying Selenium in fertilisers such as Selenistart and Selenigrass:

  • 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.
