In a herd of Holstein cows officially free of IBR, the pen housing heifers between 12 and 20 months of age has shown signs of mild illness for several days: decreased feed intake, sporadic coughing, and some listless animals.
As can be seen in the image, housing conditions are not optimal, mainly due to overcrowding relative to the available space, as well as difficulty accessing the feed bunk and a shortage of water troughs.
