My understanding is the oil suppresses the frothy bloat, sort of like salt and cold water tends to take the bubbles out of dish soap..
The oil also tends to grease up, and move any "plug" in the bowel and helps them poop out what ever is causing the problem. My understanding is one can use any kind of vegetable oil ( within reason of course!) and it will do the same job as bloat-eze. However bloat eze has flavoring in it, so the cow can taste it and know to swallow and not choke, were other oils are basically flavorless, and supposedly the cow may tend to choke on them easier than bloat-eze.
The question is why is so many of your animal all of a sudden bloating? Are they on rich legumes /alfalfa, etc and not used to it??
Just wondering..
