Part 21

_Symptoms._--Tremor of hind legs; a staggering gait, which soon terminates in loss of power in the hind limbs; pulse rises to sixty or eighty per minute; milk diminishing in quantity as the disease progresses; the animal soon goes down, and is unable to rise, moans piteously; eyes set in the head; general stupor; and slow respiration.

_Treatment._--This disease, though generally regarded as a febrile disorder, will not yield to the general practice of taking blood, as a large majority of the cases so treated die. The bowels must be opened, but the veins never. Give Epsom-salts, one pound; Jamaica ginger, two ounces; dissolve in warm water, one quart, and drench. The author usually gives with good effect, some five or six hours after the salts, two ounces of nitric ether and one ounce of tincture of opium, in half a pint of water. Rub well in, along the back and loins, the following: strong mustard, three ounces; aqua ammonia and water, each one and a half ounces. Some modifications in the treatment of this disease, as well as of most others, will be necessary under certain circumstances, which can only be determined by the veterinary practitioner.

QUARTER EVIL.

In some sections of the country, this disease--known by the other names of black quarter, and joint murrain--is quite common among young cattle, and is generally fatal in its termination. There is little or no warning of its approach. The first animals in a herd to be attacked are generally those in a full, plethoric condition.

_Symptoms._--The joints suddenly become swollen, and so painful as to produce severe lameness, particularly in the hind parts. General irritative fever exists in the system, attended with great tenderness of the loins; the head is poked out; eyes red and bulging; the roots of the horns, as well as the breath, are hot; the muzzle dry, and nostrils expanded; pulse rises to seventy or eighty, full and hard; respiration is hurried; the animal is constantly moaning, and appears to be unconscious of surrounding objects; the swelling of the limbs extends to the shoulder and haunch; the animal totters, falls and dies in from twelve to twenty-four hours.

_Treatment._--Early bleeding is requisite here, to be followed by active purgatives; after which, give one of the following powders every half hour: nitrate of potassa, two ounces; tartrate of antimony and pulverized digitalis, of each one and a half drachms; mix, and divide into eight powders. These should not be renewed. Cold linseed tea should be freely given.

RABIES.

Hydrophobia in cattle is the result of the bite of a rabid dog, from which bite no animal escapes. The effects produced by the wound made by the teeth of such an animal, after the virus is once absorbed into the circulation of the blood, are so poisonous that all treatment is useless. The proper remedies must be instantly applied to prevent this absorption, or the case is utterly hopeless. Among men, nine out of every ten bitten by rabid dogs escape the terrible effects resulting from this dreadful disorder, without resorting to any applications to prevent it. It is a well-established fact, that men, when bitten by dogs, are generally wounded in some part protected by their clothing, which guards them from the deleterious effects of the saliva which covers the teeth, and which, at such times, is deadly poison. The teeth, in passing through the clothing, are wiped clean, so that the virus is not introduced into the blood; hence the comparatively few cases of rabies occurring in man. When, however, the wound is made upon an exposed surface, as the flesh of the hand, or of the face, this fatal disease is developed in spite of every precaution, unless such precautions are immediately taken. For this reason, cattle when bitten, do not escape the disease.

_Symptoms._--The animal separates itself from the rest of the herd, standing in a kind of stupor, with the eyes half-closed; respiration natural; pulse quickened; temperature of body and limbs natural; the slightest noise agitates, causing the eyes to glare and exciting bellowing; the bark of a dog produces the most violent effects; the animal foams at the mouth and staggers as it walks; if water is offered, the muzzle is plunged into it, but the victim cannot drink; in making the effort, the most fearful consequences are produced. The animal now seeks to do mischief,--and the quicker it is then destroyed, the better.

_Treatment._--This must be applied quickly, or not at all. The moment an animal is bitten, that moment the wound should be searched for, and when found, should be freely opened with a knife, and lunar caustic, caustic potash, or the permanganate of potash at once applied to all parts of the wound, care being taken not to suffer a single scratch to escape. This, if attended to in time, will save the animal.

RED WATER.

This disease derives its name from the color of the urine voided in it. It is one of the most common complaints of horned cattle, and one of the most troublesome to manage.

_Symptoms._--Respiration hurried; rumination ceases; a high degree of fever presented; the animal moans, arches the back, and strains in passing the urine, which is tinged with blood, or presents the appearance of pure blood. Prof. Gamgee, of the Edinburgh Veterinary College, says: "The cause is almost invariably feeding on turnips that have grown on damp, ill-drained land; and very often a change of diet stops the spread of this disease in the byre. Other succulent food, grown under similar circumstances, may produce the same symptoms, tending to disturb the digestive organs and the blood-forming process.

"In the course of my investigations as to the cause of various cattle-diseases, and of red water in particular. I have found that it is unknown on well-drained farms and in dairies where turnips are used only in a moderate degree. The lands of poor people furnish the roots most likely to induce this disorder; and I can confirm the statement of the late Mr. Cumming, of Elton, who, in his very interesting essay upon this subject, says, particularly in reference to Aberdeenshire, that it is 'a disease essentially attacking the poor man's cow; and to be seen and studied, requires a practice extending into the less favorably situated parts of the country. On large farms, where good stock is well kept, and in town dairies, where artificial food is used to supplement the supply of turnips, it is seldom now seen.'

"_Symptoms._--General derangement attracts the dairyman's attention, and, upon observing the urine which the animal has voided, it is seen to be of a red, or of a reddish brown, or claret color; sometimes transparent, at others clear. The color increases in depth; other secretions are checked; the animal becomes hide-bound, and the milk goes off. Appetite and rumination are suspended; the pulse becomes extremely feeble and frequent, though--as in all debilitating, or anæmic, disorders--the heart's action is loud and strong, with a decided venous pulse, or apparent regurgitation, in the large veins of the neck.

"In some cases, if even a small quantity of blood be withdrawn, the animal drops in a fainting state. In red water, the visible mucous membranes are blanched, and the extremities cold, indicating the languid state of the blood's circulation and the poverty of the blood itself. Constipation is one of the most obstinate complications; and many veterinary surgeons--aware that, if the bowels can be acted on, the animal is cured--have employed purgatives in quantities far too large, inducing at times even death. Occasionally, diarrhoea is one of the first, and not of the unfavorable, symptoms."

_Treatment._--Give one pint of linseed-oil; clysters of soap and water should be freely used; and give plenty of linseed-tea to drink. When the urine is abundant, give one ounce of tincture of opium, with one drachm of powdered aloes, three times, at intervals of six or eight hours.

RHEUMATISM.

This is a constitutional inflammatory affection of the joints, affecting the fibrous tissue and serous, or synovial membrane. It is caused by exposure to cold and wet; being quite common in low, marshy sections.

_Symptoms._--Loss of appetite; upon forcing the animal to move, every joint seems stiffened; nose dry; coat staring; constipation is also an attendant symptom; the joints, one or more, become swollen and painful. This may be regarded as a metastic, or shifting disease; first one part, and then another, seems to be affected.

_Treatment._--Mild purgatives should be used; one-half-ounce doses of colchicum-root pulverized will be found useful; one-ounce balls of pine-tar may also be given with advantage. As a local application, the author has found nothing to equal kerosene oil, one pint, to two ounces of aqua ammonia, well rubbed in, two or three times a day.

STRANGULATION OF THE INTESTINES.

This disease in cattle,--popularly styled Knot, or Gut-tie,--in consequence of the peculiar arrangement of the abdominal viscera, is of very rare occurrence. When, however, it does occur, the symptoms accompanying are those of inflammation of the intestines.

No kind of treatment will be successful, and the poor brute must suffer until death comes to its relief.

THRUSH IN THE MOUTH.

Aptha, or thrush in the mouth, is a vesicular disease of the mouth, sometimes occurring as an epizoötic. It is often mistaken for blain,--inflammation of the tongue, or black tongue,--and usually occurs in the winter, or early in the spring. It appears in the form of vesicles, or pustules all over the mouth, occasionally extending to the outside of the lips. These pustules break, discharging a thin, sanious fluid, leaving minute ulcers in their places.

This disease yields readily to treatment, when it is properly applied. Three ounces of Epsom-salts, once a day for three or four days, should be given in drench; wash the mouth well with a solution of alum, tincture of myrrh, or vinegar and honey, and it will disappear in a few days.

TUMORS.

These enlargements so common in cattle, have been so admirably described, in the Veterinarian for 1843, by John Ralph, V.S.,--who has been so successful in the treatment of these morbid growths, that the benefit of his experience is here given. He says: "Of all the accidental productions met with among cattle, with the exception of wens, a certain kind of indurated tumor, chiefly situated about the head and throat, has abounded most in my practice.

"The affection often commences in one of the thyroid glands, which slowly but gradually increases in size, feels firm when grasped, and evinces very little tenderness. Generally the attendant is alarmed by a snoring or wheezing noise emitted by the animal in respiration, before he is aware of the existence of any tumefaction. This continues to increase, embracing in its progress the adjacent cellular and muscular tissues, and frequently the submaxillary and parotid glands. It becomes firmly attached to the skin through which an opening is ultimately effected by the pressure of pus from the centre of the tumor.

"The swelling often presents an irregular surface, and various centres of maturation exist; but the evacuations only effect a partial and temporary reduction of its bulk, in consequence of the continued extension of the morbid growth and ulcerative process which often proceed towards the pharynx, rendering respiration and deglutition still more difficult, until at length the animal sinks from atrophy or _phthisis pulmonalis_.

"In the early part of my practice, having been frustrated in my attempts to establish healthy action in these ulcers, and referring to the works that I had on surgery for information, I concluded that they bore some resemblance to cancer in the human being, and determined to attempt extirpation. Subsequently, numerous cases have occurred in which I have successfully carried that determination into effect. I have had some instances of failure, which failure always arose from some portion of the morbid growth having been left.

"In the first stage, I have reason to believe that the tumor may be dispersed by the general and topical use of the iodurets. After the suppuration, I have tried them in vain.

"As soon as the nature of the tumor is clearly developed, I generally attempt its removal, and, when most prominent by the side of the larynx, I proceed in the following manner:--Having cast the beast, turned the occiput toward the ground, and bolstered it up with bundles of straw, I proceed to make an incision through it, if the skin is free, parallel with, and over, and between the trachea and _sterno-maxillaris_, extending it sufficiently forward into the inter-maxillary spaces. If I find it firmly attached to the apex of the tumor, I then enclose it in a curvilinear incision and proceed to detach the healthy skin to beyond the verge of the tumor.

"Its edges being held by an assistant, the knife is directed downwards through the subcutaneous parts, and all those that exhibit the slightest change from healthy structure are removed.

"By tying any considerable blood-vessel before dividing it, and by using the handle of the scalpel and the fingers in detaching the portion of the parotid gland towards the ear the hemorrhage was always inconsiderable.

"The wound is then treated in the ordinary way; except that detergents and even antiseptics are often needed to arouse healthy action, and the addition of some preparation of iodine is often made to the digestive. In directing the constitutional treatment, our chief aim must be to support the animal system with plenty of gruel until rumination is restored.

"I need not note that the operation should be performed after the animal has fasted some hours.

"As the success of the operation depends on an entire removal of the diseased parts, and as the submaxillary and parotid glands, with important branches of nerves and blood-vessels, are often enveloped therein, we must not hesitate to remove the former, nor to divide the latter. It has occasionally happened that a rupture has been made in the oesophagus, or pharynx, during the operation. In that case, a portion of the gruel with which the animal is drenched escapes for a few days; but I always found that the wound healed by granulation, without any particular attention.

"The weight of these tumors varies from a few ounces to some pounds. One that I removed from a two-year-old Galloway bullock, weighed six pounds and a quarter. A considerable portion of the skin that covered it was excised and included in the above weight. It comprehended one of the parotid glands, and I had to divide the trunk of the carotid artery and jugular vein.

"This affection may be distinguished from parotiditis and other _phlegmasiæ_ by the action of constitutional disturbance, and heat, and tenderness, and by the lingering progress it makes. I was once called to a bull laboring under alarming dyspnoea that had gradually increased. No external enlargement was perceptible; but on introducing my hand into the mouth, a large polypus was found hanging from the _velum palati_ into the pharynx, greatly obstructing the elevation of the epiglottis and the passage of food. After performing tracheotomy, to prevent suffocation, I passed a ligature around its pedicle in the way suggested by the old anatomist, Cheselden.

"A section of one of these tumors mostly displays several abscesses, with matter varying in consistency and often very fetid, enclosed in what seems to me to be fibro-cartilaginous cysts, the exterior of which sometimes gradually disappears in the surrounding more vascular abnormal growth. Osseous matter (I judge from the grating of the scalpel upon it) occasionally enters into the composition of the cysts.

"I have treated this affection in cattle of the Long-horned, Short-horned, Galloway, and Highland breeds; and from the number of bulls in this class of patients, have reason to conclude that they are more liable to it than the female.

"About twelve months ago, I examined the head of a cow, on the right facial region of which there existed an enormous tumor, extending from the eye to the lips, and which I mistook during life for a periosteal enlargement. On cutting into it, my mistake was evident. There was scarcely a trace of the original bones beneath the mass; even those forming the nasal sinuses on that side were replaced by a formation much resembling the cysts before alluded to, and full of abscesses. The progress of the disease was decisively marked in the inferior rim of the orbital cavity, where the osseous matter was being removed, and the morbid structure deposited."

ULCERS ABOUT THE JOINTS.

Occasionally, the joints assume a tumefied appearance, generally ulcerating, and causing painful wounds.

_Treatment._--The application of one part of alum to two parts of prepared chalk, powdered and sprinkled upon the parts, is usually all that is required.

WARBLES.

It has been a prevalent opinion among farmers, that warbles are so many evidences of the good condition of their cattle. It must, however, be borne in mind that the warbles are the _larvæ_ of the _oestrus bovis_, which is said to be the most beautiful variety of gad-fly. This fly, judging from the objects of its attack, must be particularly choice in its selection of animals upon which to deposit its eggs, as it rarely chooses those poor in flesh, or in an unhealthy condition. From this circumstance, probably, has arisen the opinion above-mentioned.

These warbles--or _larvæ_ of the _oestrus bovis_--so nearly resemble bots in the horse--or _larvæ oestrus equi_--that, were it not for their increased size, they might readily be mistaken the one for the other. There is, however, one other difference, and that is in the rings which encircle the body; those of the former being perfectly smooth, while those of the latter are prickly, and from one third to one half smaller.

The author was called, in the year 1856, to see the prize cow, Pet, belonging to James Kelly, of Cleveland, Ohio, whose extraordinary yield of butter and milk had been reported in the _Ohio Farmer_, a short time previous to his visit. This animal was found by him in rather poor condition; the causes of which he could only trace to the existence of these worms, comfortably located, as they were, beneath the animal's hide, and forming small tumors all along the spinal column, each being surrounded by a considerable quantity of pus. A number of these were removed by means of a curved bistoury and a pair of forceps, since which time--as he has been informed--the animal has rapidly improved, regaining her former good condition.

Some may urge that this is an isolated case; but an examination of cattle for themselves, will convince them to the contrary. It may be added, that two other cows, belonging to the same gentleman, were also examined at the same time,--one of them being in good condition, and the other, out of condition. From the back of the latter several of these insects were removed, since which time she also has much improved. The former was entirely free from them. These cows were all kept in the same pasture, received the same care, and were fed on the same food, and at the same time; and as the removal of these larvæ has been productive of such beneficial results, have we not a right to infer that these insects are injurious?

If we go further and examine, in the spring of the year, all cattle which are subject to them, instead of finding them in the fine condition which one would naturally expect,--considering the abundance of fresh young grass whose vigorous life they may incorporate into their own,--they are out of condition, and out of spirits, with a laggard eye, a rough coat, and, in some cases, a staggering gait, as though their strength had failed in consequence.

How shall such attacks be prevented? During the months of August and September this gad-fly is busily engaged in depositing its eggs. Some are of the opinion that they are placed on the hairs of the animal; others, that the skin is perforated, and the egg deposited in the opening, which would account for the apparent pain manifested by cattle at and after the time of such deposit. Be this as it may, it is certain that the maggot works its way into the muscular fibre of the back, and depends upon the animal's blood for the nourishment which it receives.

The author has been informed, by persons in whom he ought to have confidence, that the _free use of the card_, during the above-named months, is a specific protection against the attacks of the _oestrus bovis_. He repeats this information here, not without diffidence; since so large a majority of stock-owners evince, by their lack of familiarity with the practical use of this convenient and portable instrument, an utter disbelief in its reliability and value.

WORMS.

Cattle are not so subject to worms proper as are the other domestic animals; nor, when these parasites do exist, is any injurious effect apparent, except it be in the case of young calves of a weakly constitution. Worms are most commonly located in the small intestines, and cause there considerable irritation, and consequently, general emaciation, or at least a tendency to it.

The cause, however, is easily removed by administering doses of sulphate of iron, one-half drachm each, in molasses once or twice a day.

WORMS IN THE BRONCHIAL TUBES.

Inflammation of the bronchial tubes is often caused by worms of the _strongylus_ species. Upon examination after death, the bronchial passages are completely blocked-up by these hangers-on.

_Symptoms._--A rough, staring coat; hide-bound; painful cough; respiration hurried, etc.

_Treatment._--But little can be done by way of treatment in this disease. The administration of small doses of spirits of turpentine has, in some instances, proved successful.

SURGICAL OPERATIONS.

CASTRATION.

The period most commonly selected for this operation is between the first and third months. The nearer it is to the expiration of the first month, the less danger attends the operation.

Some persons prepare the animal by the administration of a dose of physic; but others proceed at once to the operation when it best suits their convenience, or that of the farmer. Care, however, should be taken that the young animal is in perfect health. The mode formerly practised was simple enough:--a piece of whip-cord was tied as tightly as possible around the scrotum. The supply of blood being thus completely cut off, the bag and its contents soon became livid and dead, and were suffered to hang, by some careless operators, until they dropped off, or they were cut off on the second or third day.

It is now, however, the general practice to grasp the scrotum in the hand, between the testicles and the belly, and to make an incision in one side of it, near the bottom, of sufficient depth to penetrate through the inner covering of the testicle, and of sufficient length to admit of its escape. The testicle immediately bursts from its bag, and is seen hanging by its cord.
