CALVING.
Signs of Normal Calving are firmness and enlargement of the udder, extending well forward following the milk veins. The teats as a rule discharge a thin milky fluid, relaxation of the muscles on each side of the croup or the base of the tail. The outer surfaces of the womb becomes swollen and inflamed, discharging sticky, stringy, transparent mucus. The cow becomes uneasy, stops eating, and if in a pasture becomes separated from the rest of the herd; will lie down and get up alternately as if in great agony. When birth pains start, the back is arched, and a severe straining follows the contraction of the abdominal muscles. The membranes covering the fœtus will be the first to make their appearance, engorged with a fluid from the womb. This is commonly known as the water bag, which eventually bursts and the two fore feet can be seen, and, as the animal continues to strain, the nose and head will be next to be seen. When the calf’s shoulders are exposed, the cow as a rule rises suddenly to her feet and the entire calf is expelled, also the membranes surrounding it, but the membranes next to the womb, as a general rule, remain longer and sometimes require artificial assistance to remove them. (See Retention of the Afterbirth.) Destroy the fœtal membranes by burning or burying them deeply. Do not permit the cow to eat them. Wash the calf’s navel with Bichloride of Mercury, one part to one thousand parts water, once or twice a day until the navel is thoroughly dry, or an infection may follow, producing Joint Ill or Scours, from which death may result.
Abnormal Calving.—This is a condition where the fœtus is not normally presented, as that just described. Their feet may be presented in a normal manner, but the head and neck twisted back or to one side, or the head and one fore foot may be presented normally, while the other fore foot is doubled back, or there may be a breech presentation as the rump of a fœtus with both hind feet thrown close to its body. This is a very difficult presentation, especially if in a young animal. A fœtus abnormally presented requires good judgment and cleanliness, also lubrication of the walls of the womb with unsalted Lard, Cotton or Sweet Oil. Endeavor to place the fœtus in as near a normal position as possible before any force is used in its delivery, although where both hind feet are presented, it is advisable to remove it in this position. The hands and ropes should be clean and washed with a five per cent solution of Carbolic Acid. It is not only dangerous to the animal, but to the operator as well, if proper antiseptic precautions are not practiced.
Space does not permit me going into details on various fœtal presentations nor does it permit me to explain the exact methods or operations I would use in each particular case. Nevertheless, good judgment and cleanliness are important. Do not hurry. Take your time, and you will be successful in most cases.
When the fœtus is removed, and the afterbirth does not come away within twelve or eighteen hours, remove it. (See Retention of Afterbirth, which will describe its means of attachment and its removal.)
CASTING THE WITHERS.
(Eversion of the Womb)
Cause.—Failure of the womb to contract after Calving. If the womb contracts naturally and the afterbirth expelled, the cavity of the womb is nearly closed and the neck of the womb becomes so narrow that the hand cannot be inserted. When the womb fails to contract, one or both horns of the womb become so relaxed that they fall into the cavity causing straining and contraction of the abdominal muscles, forcing the womb out gradually until the organ is turned inside out. The womb can be easily distinguished from the other membranes on account of the presence of sixty to eighty mushroom-like bodies (cotyledons) two to four inches in diameter attached to the walls of the womb by a narrow neck. The womb when hanging out becomes engorged with blood and inflamed until it is as large as a grain sack, very dark in color, tears and bleeds with the slightest touch. Later it becomes lacerated and gangrenous.
Symptoms.—At first, the general health is not very much interfered with, but the inflammation which is marked by an elevation in temperature becomes very noticeable, accompanied by severe straining and exhaustion. The animal lies down, but continues to strain until death, unless relief is afforded the animal at once.
Treatment.—Great care must be exercised. The parts of the womb coming in contact with the cow’s hips, tail or floors must be thoroughly washed with a five per cent solution of Carbolic Acid, using a soft cloth or sponge to remove dirt, clots, etc. Place the cow in a position so as to have her hind quarters much higher than the head, and then endeavor to replace the womb. After washing as stated above, bandage the tail with a clean cloth; have an assistant hold up the womb and the operator use gentle manipulation and pressure with clean hands; this perhaps is the best method of replacing the womb. Then follow by flushing out the womb with a weak Carbolic Acid solution and luke warm water. This has a tendency to straighten out the horns of the uterus and prevent infection. If the cow continues to strain, give Potassium Bromide in ounce doses every two or three hours in her drinking water, or place in capsule and give with capsule gun.
