Bought a new heifer calf yesterday and picked her up this evening. Everything worked fine, loaded her up and headed home. When I got home and unloaded I noticed she had scoured a littl on her back end. . When I pulled trailer in to wash rack to wash down, I noticed where she had scoured on the trailer side. She was scheduled to get wormed, pneumonia vaccine, multi min shot and Cylence fly control down her withers to tail, also she will be tagged and booked. Due to a sudden funeral this will have to be moved to Thursday this week. She is now in the holding pen with 2 other heifer calves about the same age and all three will get the same treatment as outlined above. My concern is the scours I saw. Any thing I need to look for or do. She is 12 monyhs old and I have no history as to any wormers or vaccines given. I bought her from a guy that had bought her in a lot of 4 calves. She is full blood angus beef cow from her looks. Maybe 550-575 lbs. All 3 are with in a month of each other in age.
