about 3-4 weeks ago we found one of our charolais cows, who is feeding a calf who is 4 months old, in the paddock. her breathing was rapid and made a kind of schreeching sound as she inhaled. when made to walk she grunts as though she is short of breath and has asthma like symptoms. she has since lost a sickening amount of weight and she is always sitting down. we have treated her with anti-biotics for the past 4-5 days, hoping it would cure whatever she has. So far no luck. if you have any idea of what could be wrong with our dear cow, please let me know. im afraid she wont be around much longer but it would help to know what we are dealing with.
