Dicalcium Phosphate and hay storage

Hi Dr Getty,

Please could you tell me what dicalcium phosphate is used for, and how much of it you should feed?

I'd also like to know how to store 120 bales (4 months worth) of grass hay so that I have stock for winter and so that it won't go mouldy? How should I pack them to avoid this?

Re: Dicalcium Phosphate and hay storage

Another question, the grass my horses stand on, and nibble on when their hay is finished is about 7cm high or less and low in calcium. They are both on about 14kg of grass hay each, with a bit of bran (maxiumum 500g) for their supplements would eating a bit of low calcium grass make a difference to their ca:ph ratio which is 1:6-2 I have calculated.

Re: Dicalcium Phosphate and hay storage

Hi Christine,

You want to make certain that the amount of calcium is twice the amount of phosphorus. So, it sounds like you've already done some calculations to figure out the amount of each mineral. Add dicalcium phosphate accordingly to bring up the calcium level. Or you may simply be able to remove the bran component (which is high in phosphorus) from the diet, which will bring the calcium concentration higher.

If you need help with the calculations, I can certainly assist you.

About the hay storage -- you want to keep the hay covered so that it doesn't get wet and it is protected against the sunlight. If there is adequate air circulation, it should not mold unless it was baled while still wet.

Thanks for writing!
