:?: I've got a 18-24 month old heifer (approx. 500lbs) that looked healthy 2 weeks ago, now she's drawn down (extremely fast), NO energy, sunken eyes, and some drooling/salivating. I haven't notice any other "outward" syptoms, and she she appeared to be in perfect health at the last pen up. I've got her seperated from the herd, and gave her 22Ml of Duramycin 72-200 - didn't know what else to do. Any suggestions, ideas, or thoughts would be appreciated. I'm on my own in the family cattle business now, for the first time, and would sure appreciate some advise from you "old-timers" or ranchers in-the-know!!!
