No-Scour Calf’s active ingredient mops up bacterial toxins of pretty much any flavor preventing them from running amok in the calf’s intestine. This effectively disempowers the bug while still allowing an immune response to be generated.
Since trials began on farm (and over 900 farms have had the opportunity to trial it), 72% of calves have recovered without antibiotics or further treatment. Of the rest, most had endured previous treatments and antibiotics before the No-Scour Calf was used. It certainly warrants a try on your farm.
