We have a 2-year-old heifer, which, two weeks before she was due to
freshen, had a large udder slightly caked. Upon pressing the teat a
discharge of blood issues from each teat.
This is infectious mastitis. It may be due to a bruise or blow or
infection introduced through the milk duct. The first is most likely.
Apply camphorated oil externally and inject into the affected udder some
hydrogen dioxide (peroxide of hydrogen. - EDITOR.). After ten minutes,
milk out again. Repeat once daily.
