Part 10

Symptoms.--The calf is depressed; appetite is poor; sometimes there is fever; the extremities are cold. The dung becomes gradually softer and lighter in color until it is cream colored and little thicker than milk. It has a most offensive odor and may contain clumps of curd. Later it contains mucus and gas bubbles. It sticks to the hair of the tail and buttocks, causing the hair to drop off and the skin to become irritated. There may be pain on passing dung and also abdominal or colicky pain. The calf stands about with the back arched and belly contracted. There may be tympanites. Great weakness ensues in severe cases, and without prompt and successful treatment death soon follows.

Treatment.--Remove the cause. Give appropriate feed of best quality in small quantities. Make sure that the cow furnishing the milk is healthy and is properly fed. Clean all milk vessels. Clean and disinfect the stalls. For the diarrhea give two raw eggs or a cup of strong coffee. If the case is severe, give 1 ounce of castor oil with a teaspoonful of creolin and 20 grains of subnitrate of bismuth. Repeat the bismuth and creolin with flaxseed tea every four hours. Tannopin may be used in doses of 15 to 30 grains.

Calves artificially fed on whole or skim milk should receive only such milk as is sweet and has been handled in a sanitary manner. Milk should always be warmed to the temperature of the body before feeding. When calves artificially milk-fed develop diarrhea, the use of the following treatment has given excellent results in many cases: Immediately after milking, or the separation of the skim milk from the cream, formalin in the proportion of 1 to 4,000 should be added to the milk which is used for feeding; this may be closely approximated by adding four drops of formalin to each quart of milk. This medicated milk should be fed to the calf in the usual quantity. When the diarrhea is not controlled in three or four days by this treatment, the additional use of some of the agents recommended above may assist in a recovery.

INFECTIOUS DIARRHEA; WHITE SCOUR.

GASTROENTERITIS.

This consists of an inflammation of the walls of the stomachs and of the bowel.

Gastroenteritis, or inflammation of the walls of the stomachs and intestines, follows upon irritations more severe or longer continued than those that produce gastrointestinal catarrh.

Causes.--Severe indigestion may be followed by gastroenteritis, or it may be caused by swallowing irritant poisons, such as arsenic or corrosive sublimate or irritant plants. Exposure to cold or inclement weather may produce the disease, especially in debilitated animals or animals fed improperly. It is asserted that if cattle feed on vegetation infested with some kinds of caterpillars this disease may result.

Symptoms.--Dullness; drooping of the ears; dryness of the muzzle; dry skin; staring coat; loins morbidly sensitive to pressure; fullness of the left flank, which is caused by the distention of the fourth stomach by gas. The pulse is small, the gait is feeble and staggering; each step taken is accompanied with a grunt, and this symptom is especially marked if the animal walks in a downward direction. There is loss of appetite, and rumination is suspended. The passages at first are few in number, hard, and are sometimes coated with mucus or with blood. Later a severe diarrhea sets in, when the passages contain mucus and blood and have an offensive odor. There is evidence of colicky pain, and the abdomen is sensitive to pressure. Pain may be continuous. There is fever and acceleration of pulse rate and respirations. Mental depression and even insensibility occur before death. The disease is always severe and often fatal.

Post-mortem appearances.--The mucous membrane of the fourth stomach has a well-marked red color and sometimes presents ulcerations. The wall is thickened and softened, and similar conditions are found in the walls of the intestines. The red discoloration extends in spots or large areas quite through the wall, showing on the outside.

Treatment.--Very small quantities of carefully selected feed must be given and the appetite must not be forced. Protect the animal well from cold and dampness. Internally, give linseed tea, boiled milk, boiled oatmeal gruel, or rice water. These protectives may carry the medicine. Tannopin in doses of 30 to 60 grains is good. Subnitrate of bismuth in doses of 1 to 2 drams may be given. Pulverized opium may be used, if the diarrhea is severe, in 1 to 2 dram doses. If the bowel movements are not free, one may give from a pint to a quart of castor or raw linseed oil.

TRAUMATIC INFLAMMATION OF THE STOMACH.

This disease results from the presence of a foreign body. This condition is not rare in cattle, because these animals have the habit of swallowing their feed without careful chewing, and so nails, screws, hairpins, ends of wire, and other metal objects may be swallowed unconsciously. Such objects gravitate to the second stomach, where they may be caught in the folds of the lining mucous membrane, and in some instances the wall of this organ is perforated. From this accident, chronic indigestion results. The symptoms, more or less characteristic, are pain when getting up or lying down; grunting and pain upon sudden motion, especially downhill; coughing; pain on pressure over the second stomach, which lies immediately above the cartilaginous prolongation of the sternum. If the presence of such a foreign body is recognized, it may be removed by a difficult surgical operation, or, as is usually most economical, the animal may be killed for beef, if there is no fever.

DISEASES OF THE BOWELS.

DIARRHEA AND DYSENTERY.

The word "dysentery," as it is commonly used in relation to the diseases of animals, signifies a severe form of diarrhea.

Causes.--Diarrhea is a symptom of irritation of the intestines, resulting in increased secretion or increased muscular contractions, or both. The irritation is sometimes the result of chilling from exposure, improper feeding, irritant feeds, indigestion, organic diseases of the intestines, or parasites.

Symptoms.--Passages from the bowels are frequent, at first consisting of thin dung, but as the disease continues they become watery and offensive smelling, and may be even streaked with blood. At first the animal shows no constitutional disturbance, but later it becomes weak and may exhibit evidence of abdominal pain by looking around to the side, drawing the feet together, lying down, or moving restlessly. Sometimes this malady is accompanied with fever, great depression, loss of strength, rapid loss of flesh, and it may terminate in death.

Treatment.--When the disease depends on irritating properties of the feed which has been supplied to the animal, it is advisable to give a mild purgative, such as a pint of castor or linseed oil. When the secretions of the bowels are irritating, an ounce of carbonate of magnesia and half an ounce of tincture of opium should be shaken up in a quart of linseed tea and given to the animal three times a day until the passages present a natural appearance. When there is debility, want of appetite, no fever, but a continuance of the watery discharges from the bowels, then an astringent may be given. For such cases the following is serviceable: Tannic acid, 1 ounce; powdered gentian, 2 ounces; mix and divide into 12 powders, one powder to be given three times a day until the passages present a natural appearance. Each powder may be mixed with a pint and a half of water. Tannopin is a new remedy that is most useful in such cases. The dose is from 30 grains to 2 drams. Useful household remedies are raw eggs, strong coffee, parched rye flour, or decoction of oak bark. In all cases the food must be given sparingly, and it should be carefully selected to insure good quality. Complete rest in a box stall is desirable. When diarrhea is a symptom of a malady characterized by the presence of a blood poison, the treatment appropriate to such disease must be applied.

SIMPLE ENTERITIS.

CROUPOUS ENTERITIS.

Under certain conditions, severe irritation of the digestive canal may, in cattle, cause a form of inflammation of the intestines (enteritis) that is characterized by the formation of a false membrane upon the surface of the lining membrane of the intestines, particularly the large ones.

Symptoms.--There is fever, depression, loss of appetite, diarrhea, and in the fecal masses shreds of leathery false membrane may be found. These shreds are sometimes mistaken for parasites or for portions of the wall of the intestine.

Treatment.--Give a pound of Glauber's salt, followed by bicarbonate of soda in doses of 2 ounces four times daily.

ENTERITIS (OBSTRUCTION RESULTING FROM INVAGINATION, OR INTUSSUSCEPTION, TWISTING, AND KNOTTING OF THE BOWELS).

Inflammation may arise from a knot forming on some part of the small intestine from the portion of the bowel becoming twisted on itself, or from one part of the bowel slipping into another, which is termed invagination. This form of enteritis occurs occasionally in animals of the bovine species.

Causes.--The small intestine, which in the ox rests on the right side of the rumen, is, from the position which it occupies, predisposed to this accident. It has been ascertained that animals which have shown symptoms of this malady have trotted, galloped, or made other violent exertions in coming from drinking, or that they have been chased by dogs or by animals of their own species while at pasture. The accident is most likely to occur among cattle on very hilly pastures. The danger of jumping or running is greatest when the rumen is distended with food.

Symptoms.--This form of enteritis or obstruction is manifested by severe colicky pains; the ox scrapes and strikes the ground with his front and hind feet alternately; keeps lying down and getting up again; he keeps his tail constantly raised and turns his nose frequently to his right flank; he is frequently bloated, or tympanitic, on that side. He refuses feed and does not ruminate, and for some hours suffers severe pains. At first he frequently passes thin dung, and also urinates frequently, but passes only a little urine at a time. On the second day the pains have become less acute; the animal remains lying down; moans occasionally; his pulse is small and quick; he still refuses feed and does not ruminate. At this stage he does not pass any dung, though sometimes a small quantity of bloody mucus may be passed. The animal passes very little urine. This condition may continue for a considerable time, as cattle so affected may live for 15 or even 20 days.
