We have some great articles in this issue. Dr. Kip Lukasiewicz’s article on the impact of mud is a must read, particularly with the severity of the winter some long-term forecasts are expecting. Another very relevant article is Dr. Gregg Hanzlicek’s article on coccidiosis. On the topic of bovine respiratory disease complex is Dr. Brent Meyer’s article on bovine coronavirus. Although we are all tired of hearing about human coronavirus, there is a reason these viruses are so important to our industry and all animal industries. Dr. Dan Thomson addresses one of the oldest practices humans ever performed on domestic cattle – castration procedures – with a modern approach to welfare considerations. Ever-changing technology leads to more questions on communication and security, which are discussed by Dr. Nels Lindberg and Richard Fleeman. Finally, Dr. Duane Wulf discusses an ever-important topic in our industry, dark cutters.
