Besides the importance of proper care and feeding of the cow as a preventive measure, attention should be given at once to relieve the newborn calf of its investing membrane and of any mucus that has collected in mouth or nostrils. Wiping out the nose deeply with a finger or feather excites to sneezing, hence to breathing. Blowing into the nose has a similar effect. Sucking the nostril through a tube applied to it is even more effective. Slapping the chest with the palm of the hand or with a towel dipped in cold water, compression and relaxation alternately of the walls of the chest, may start the action, and ammonia or even tobacco smoke blown into the nose may suffice. Every second is precious, however, and if possible the lungs should be dilated by forcibly introducing air from a bellows or from the human lungs. As the air is blown in through bellows or a tube the upper end of the windpipe must be pressed back against the gullet, as otherwise the air will go to the stomach. In a large dairy a piece of elastic tubing one-third of an inch in bore should be kept at hand for sucking and blowing in such cases.
BLEEDING FROM THE NAVEL.
This may occur in two conditions—when the cord is cut off too close to the navel and left untied and when it tears off at the navel. ([Pl. XIV].) It may also bleed when torn across naturally, if it is sucked by the dam or another calf. In an animal with little plasticity to its blood it will flow under almost any circumstances. When any cord is left it is always safe to tie it, and it is only when it is swollen and may possibly contain a loop of the bowel that there is danger in doing so. By pressing upward any bulky contents such danger is avoided. If torn or cut too close to be tied the bleeding may be checked by applying alum, copperas, or for a fraction of a second the end of an iron rod at a dull-red heat. If much blood has been lost it may be requisite to transfuse several ounces of blood or of a weak, common-salt solution into the open, umbilical vein.
URINE DISCHARGED THROUGH THE NAVEL (PERSISTENT URACHUS).
Before birth the urine passes from the bladder by a special tube through the navel and navel string into the outer water bag (allantois). ([Pl. XII].) This closes at birth, and the tube shrinks into a fine cord up to the bladder. It is only in the bull calf that it is liable to remain open, doubtless because of the long, narrow channel through which the urine must otherwise escape. The urethra, too, is sometimes abnormally narrow, or even closed, in the male. If part of the cord remains, it should be tied and the whole allowed to wither up naturally. If the cord has been removed and the tube (urachus) protrudes, discharging the urine, that alone must be tied. If there is nothing pendent the urachus must be seized, covered by the skin, and a curved needle being passed through the skin and above the duct, it may be tied along with this skin. A blister of Spanish flies, causing swelling of the skin, will often close the orifice—so with the hot iron. If the urethra of the male is impervious it can rarely be remedied.
INFLAMMATION OF THE URACHUS (NAVEL URINE DUCT).
This may originate in direct, mechanical injury to the navel in calving, or shortly after, with or without the lodgment of irritant or septic matter on its lacerated or cut end. The mere contact with healthy urine, hitherto harmless, can now be looked on as becoming suddenly irritating. The affection is usually marked by the presence of redness and swelling at the posterior part of the navel and the escape of urine and a few drops of whitish, serous pus from the orifice of the urachus. In those cases in which urine is not discharged a tender swelling, like a thick cord extending upward and backward from the navel into the abdomen, may be identified. The navel enlargement may be considerable, but it is solid, does not gurgle on handling, and can not be done away with by pressing it back into the abdomen, as in a case of hernia.
In cases at first closed the pus may burst out later, coming from the back part of the navel and the swelling extending backward. In other cases whitish pus may pass with the urine by the ordinary channel, showing that it has opened back into the bladder. In other cases the umbilical veins become involved, in which case the swelling extends forward as well as backward. Thus the disease may result in destructive disorders of the liver, lungs, and, above all, of the joints.
The disease may usually be warded off or rendered simple and comparatively harmless by applying antiseptics to the navel string at birth (carbolic acid 1 part, water and glycerin 5 parts each, or wood tar). Later, antiseptics may be freely used (hyposulphite of soda 4 drams, water 1 quart) as an application to the surface and as an injection into the urachus, or even into the bladder if the two still communicate. If they no longer communicate, a stronger injection may be used (tincture of chlorid of iron 60 drops, alcohol 1 ounce). Several weeks will be required for complete recovery.
