BIG KNEE.
—Often cattle show large bunches over the knees. These may be soft or hard. In cattle these big knees are caused by hard floors, in lying down and getting up. Big knee in horses is a little different, being more in the nature of spavin or ringbone, and in this case occurring at the knee joints. In cattle the bunch may be localized in the flesh and skin. With horses, it is an attack on the bony structure. When first noticed a blister may be used.
