Anybody use Cropsaver preservative?

Two years ago I bought a liquid applicator for my baler, to apply cropsaver preservative. I had hoped it would allow me to bale later in the evening, earlier in the day, and help with early first cutting. I used it once, on hay that I knew was a little tough, but not too bad. The hay did not keep very well, and I never used the thing again. I'm thinking of having another go at it, this time with a baler mounted moisture monitor. Has anyone had much luck with this stuff? It is plenty humid here in the summer. I am baling for horses, so the hay has to smell and look good. Thanks for any advice,
Josh
 
I have not used that brand but most of it is a mix of propionic acid. I have been told that horses don't like hay treated with preservatives.

Another thing to remember is hay preservatives make the hay have a shelf life. Meaning that the hay can spoil after a period of time. The preservatives quit working. This usually after 8-12 months. It is shorter the higher the moisture your hay is.
 
I agree with JD on the use of preservatives for horses...at the least it is questionable. I disagree with "preserved" hay having a shelf life. I have used prop. acid for several years now and have never had a batch of hay go bad. It is imperative that you know the moisture content of the hay and apply the correct amount of preservative accordingly. This means a chamber mounted moisture meter and setting your pump accordingly. You also have to know how much you are baling on a per ton basis per hour. Preservatives are applied on a "per ton" basis based on the % of moisture. To determine this, bale for a set amount of time and then count and weigh the bales. Then you know how much you are baling per hour. Preservatives work if you put on the correct amount. In laymen's terms, it kills off the bad bacteria that cause spoilage long enough for the hay to naturally dry down. Using perservatives is kind of a pita, but if you want it to work properly, you have to take the necessary steps.
