NAG Bags is always recommencing hay testing? Why? It's such a small price to pay for the benefits it will give you, and you're stuck.
We have had customers that have purchased a barn full of hay and have sore horses in a week! Too much sugar or too much protein for their animals' needs.
As for most horses, hay is about 97% to 100% of your grazing animals' diet, so we need to get it right.
Slow feeders are only as good as the hay type matching the horses' needs - rich hay is still rich hay in a slow feeder. Yes, it will make intake somewhat slower ( which is excellent), but the overall goal is to have hays available for your animal 24 hours a day, without the fears of laminitis and obesity.
Check and ask your suppliers - do you have a hay test? If not its a usually under 45 dollars to have done and a great piece of mind. You then can balance your horse's complete ratio after you have this.
See below hay sites and ways to sample your hay. You do not need a core sample to get a hay test done. Use a coat hanger and push into at least nine different bales for a small center sample, place into a large ziplock, label, and you're ready to mail! Simple!
These websites offer information on feeding equines and the insulin-resistant horse, and how to keep your equine in balance. From forage to balancing the minerals, and keeping feeding as natural as we can. Benefits the equine's health, physically and emotionally.
