not produce any
disturbance in her.
This is a very common malady in most places. I have known several
instances on particular farms where they were unable to raise either
foals or calves, but if the mother were removed to another farm
immediately after or before foaling, the foal or calf lived and was
reared without difficulty, and although constitutional debility plays an
important part, the presence of specific germs constituting an infected
area is, I believe, the most important factor in producing this disease.
According to my observation, about seventy-five per cent of the cases
die within the first three weeks after birth. This high rate of
mortality would be considerably diminished if proper treatment was
adopted.
SYMPTOMS: The attack usually comes on during the second or third week
after birth and almost always before the closure of the navel opening,
which, in affected animals, will be found to be in a wet and suppurating
condition. Occasionally foals two or three months old which have the
urachus closed and are in an apparently healthy condition contract this
disease in a form of painful swelling of the joints. The first symptoms
are generally dullness; more or less fever; lameness which is often
attributed to rheumatism or to injury caused by the mare treading on the
foal; the disinclination to move or even to stand. Upon examination the
patient will be found to have a soft, gelatinous swelling of one or more
of the joints of which the hock, elbow, fetlock, stifle and hip usually
manifest the enlargement most clearly.
These swellings are hot and painful to the touch; they tend to suppurate
and frequently cause intense lameness. In very rare cases open urachus
may exist without any joint inflammation. In this disease, inflammation
of the joints and open urachus are almost always co-existent.
Animals that recover from a bad attack are seldom worth the trouble of
rearing, because as a rule their constitution becomes permanently
impaired and one or more of their joints becomes stiffened by the
attack.
TREATMENT: In the treatment of this disease, we have to attend to
constitutional disturbances, inflamed joints, open urachus and
complications such as constipation and diarrhoea. The comfort of our
little patient must be studied under all circumstances. If the weather
be at all cold it should be covered by a warm sheet. Should the foal
have any difficulty in rising from the recumbent position, an atte
