How to Make Sense of Pasture Analysis Results

Have you ever got the results back from a pasture or hay analysis and been left scratching your head trying to figure out what the numbers mean? Frustrating isn’t it!?

That is unless you have a tool (like FeedXL) to interpret the numbers for you.

Let me show you what I (Nerida) mean. The analysis below shows the analysis result numbers for the bottom pasture at our place, but they are kind of meaningless unless we look at them in terms of how much of that pasture a horse eats and how much nutrient is provided compared to the amount of nutrient the horse actually needs.

Take phosphorus for example, the pasture contains 1.45 g/kg of phosphorus, which is only enough to meet 39% of a late pregnant (month 11) mare’s requirement if she was given full time access to this pasture.

Our pasture is native pasture and our soils are low in phosphorus so the pasture is lower in phosphorus than most pastures. BUT, point is 1.45 g/kg of phosphorus was only a number until we put it in terms of what our late pregnant mare needs each day to meet her requirement (note to my husband, we don’t have a late pregnant mare, this is just an example, in case you are panicking right now! No promises for the future though, it’s all part of my professional development right! )

You will also see from the diet readout from FeedXL below that the pasture only diet (bar graph with the green and red bars) is not meeting requirements for multiple other nutrients for this late pregnant mare, which also would have been difficult to determine just from reading the analysis numbers alone.

 

So with FeedXL we can see what is not in your pasture that your horse needs. You can then also add other feed ingredients to the diet to meet those requirements.

The second bar graph with the green and blue bars shows a diet I would use for a late pregnant mare on this pasture. The diet uses 2 kg of prime lucerne hay (shown in the darker green) and 3 kg of a commercial broodmare feed (shown in the blue). All requirements are now nicely met!

Pasture analysis made that bit more useful! Using FeedXL to assess your forage analysis also means you will only supplement with the nutrients you need to add, potentially saving yourself a lot of money by not adding unnecessary products and nutrients.

You can upload as many pasture and hay analyses as you like into your FeedXL account, just click the ‘Add my own forage’ link in the Create Forage section of the diet wizard, or directly from the Feeds list (see below). Click here to log in and give it a try!
