This is an inflammation of the udder, sometimes known as "caked bag,"
with or without general inflammation. Where it is simply an inflammation
of the udder, it is usually caused by too great an accumulation of milk
in the latter prior to lambing, or in consequence of the death of the
lamb.
_Treatment._ Drawing the milk partly from the bag, so that the hungry
lamb will butt and work at it an unusual time in pursuit of its food,
and bathing it a few times in _cold_ water, usually suffices. If the
lamb is dead, the milk should be drawn a few times, at increasing
intervals, washing the udder for some time in cold water at each
milking. In cases of obdurate induration, the udder should be anointed
with iodine ointment. If there is general fever in the system, an ounce
of Epsom salts may be given. If suppuration forms, the part affected
should be opened with the lancet.
