We have a heifer that has started to bloat just a little. She has been on feed for several months so there hasn't been any drastic changes for her. She has just started this a few weeks ago. It isn't bad and goes away. Since she's started it, we've increased her dry hay (brome) and taken away the alfalfa. we've dropped some corn out of her ration and upped the oats, we've increased her exercise. This morning she was fine, we fed her and just went out a little bit ago and she is aired up again. She is almost where we want her condition-wise so I hate to back her off too much but then again, we can't have her bloating all the time. We are going to try a bloatguard block but have no idea if she'll get enough from it or not. I can order the product in to put directly in her ration if the block won't work. However, I'm not sure this will fix the problem. Any ideas?
