Don’t let Selenium hold back your livestock performance
For April we shouldn’t overlook the opportunity of fortifying grass for grazing and silage with selenium (Se). Data from Yara analytical services shows that more than 90% of grass and grass silage samples tested are deficient in selenium.
Increasing the Se levels in grass can significantly reduce health problems and improve reproductive performance in livestock. Using a fortified fertiliser ensures that grass or silage has Se levels which meet the animal’s requirements of 0.2-0.3 mg/kg DM.
For grazing, YaraMila Stock Booster S (25-5-5 + 5 % SO3 + Se) is a perfect choice to drive grass growth in April, by providing the N, P, K and S that grass needs as growing conditions improve. The selenium in this product will boost the selenium concentration in grass for grazing livestock which is particularly important for lactating ewes and cows. Livestock utilise the Se in grass and silage more efficiently than the Se found in boluses, licks and TMR mineral mixes.
As spring calving dairy and suckler cows reach peak milk in April and May, which coincides with the start of breeding, it's crucial that Se intakes are adequate for lactating cows at grass to ensure good reproductive performance. By using YaraBela Nutri Booster (25% + 5% SO3) or YaraMila Stock Booster S, you are effectively increasing the selenium levels in every bite of grass for your grazing livestock.
