I ordered some of this. I have used it on one calf so far. I dont normally have a lot of trouble but there is that one to two percent of calves that will have some sort of problem. If it helps these it will be more than worth the cost and the others will benefit too. They need to improve their web site and show what is actually in in the product. When you get it it has a sheet that shows that and there is alot in it.
