We had a Kadabra calf that started getting too straight and tight through his hips back in July. We started him on Natural Stride then and we are just now running out of the first bucket. It hasn't cured him so to speak, but he hasn't gotten any worse either. I suspect he would have been in pretty bad shape if we hadn't used it.
We have used it and liked it. We think that it helps the move out more fluidly and set down on their pastern better. I dont think it will cure a cripple, but I think it will help minor issues, and ours love the taste of it.
How much natural stride are you giving? I have been giving it to our show hogs for a little preventative maintenance. 1 small scoop, twice daily mixed in with feed. By the way....it smells wonderful!!!
I would recommend just following the instructions on the tub, and then depending on the results u get, either increase or decrease the amount. We always increase the amount 2 weeks before a show, it just gives them that little extra flex in the ring.
