A hallmark sign of Winter Dysentery is a sudden onset of explosive diarrhea. The diarrhea is usually dark green to black in color and may, at times, contain blood. Animals affected with Winter Dysentery could have some mild coughing, nasal discharge and general dehydration. Another sign of Winter Dysentery is a decrease in feed intake. Make sure to work with your nutritionist to keep a watchful eye on feed intakes at all times. Lowered body condition, caused by a decrease in feed intake, can have a detrimental effect on the animal. The combination of dehydration and decreased feed intake can lead to a drop in milk production. Milk production can decrease significantly (25%-95%) depending on how rapidly the disease is diagnosed and treated. This drop in milk production can take months to recover, decreasing your bottom line profit.
