I always feed milk from the cows. Much better for the animals. How about trying to mixing in some diatomaceous earth DE. I use 1 cup per 50-80 litres, once per day, never had one case of scours.What if any are the effects of feeding fresh milk containing various antibiotics to calves.has it any adverse effects on good bugs in the calfs stomach. Does it have any negative or positive effects on calf scour,
