Don't feed it to bulls that you plan to breed with. The syrup that I used several years ago was thin and we never had problems with bloat, but it did cause the bulls to become sterile for a period of time. I lost my favorite Angus bull for a breeding season because of this. Fortunately, we found out and pulled him and got him tested (and had a young spare bull). He was fine the next Spring and for the next 2 years.
