i have 5 bottle calves that are scouring. 1 is three weeks old who was scouring 3 days after she was born, i treated her and she was fine untile 2 1/2 weeks later i seen she had navel infection. when i started treating her for navel ill, she started scouring again? the other four were scouring a few days after i got them. i also have a bigger calf(150 lbs of the mother) she is weaned and she also seems to have diahrea or watery feces. 2 of the calves drink less then they ussually do? the milk i feed the calves is supposed one of the best kind? does any one know what the problem could be?
