Phosphorus is particularly beneficial for growth, lactation and fertility and is essential for stock grazing pasture in low phosphorus areas.


The lack of phosphorus and magnesium can often be limiting factors for stock grazing green feed so there is the opportunity to maximise stock performance by supplementing additional phosphorus and magnesium at this time.


Phosphorus is one of the most important minerals in animal nutrition and is essential for appetite, efficiency of feed utilisation, bone growth and fertility. To ensure the maximum response to phosphorus supplementation, MegaMin Extra Phosphorus is formulated to provide calcium, sulphur, manganese and copper.


Why broad spectrum Minerals are essential

Macro minerals and trace minerals are needed year round by livestock for optimum production, health and fertility. Read more>


Why Phosphorus is important

  • Phosphorus deficiency can cause poor growth rates and low calving percentages.
  • When there is plenty of lush green feed during Spring or a wet season, phosphorus is likely to be the major limiting nutrient, especially in phosphorus deficient areas.
  • Phosphorus is a crucial nutrient for converting feed into energy.
  • When magnesium is fed over an extended period, it is important to add phosphorus as a precautionary measure because magnesium can reduce phosphorus absorption.

Product Enquiry

Phosphorus deficiency...

“Steers didn't perform in our native grass areas which were phosphorus deficient and bone chewing and botulism was a big concern. In these areas, we now supplement year round with MegaMin Extra Phosphorus because it also provides a broad range of minerals. Intake variations did occur throughout the season however our cattle have stopped chewing bones."


“MegaMin has done a great job in our Phosphorus deficient country and has also ensured that our stock maintained good condition last winter.”
