scaling beef

In this Jan. 20, 2012 photo, animal science research assistant Zach Sawall guides a calf on to a scale at the Dairy Teaching & Research Center in St. Paul, Minn. Noah Litherland feeds his research subjects ? young dairy calves ? twice a day as they sit in their small hutches outside the dairy farm on the University of Minnesota's St. Paul campus. Litherland, an assistant professor in the Department of Animal Science, and a team of students are looking at the cows to provide insight into cold stress in calves and their growth responses in the cold winter weather.
