CATTLE AND THEIR DISEASES TEXT

charcoal applied to the parts will be found useful. NAVEL-ILL. Inflammation of the navel in calves occasionally occurs, causing redness, pain, and sudden swelling in the part affected. This disease, if not promptly attended to, speedily carries off the creature. _Treatment._--Foment the part well with warm hop-tea; after which, the application of a cloth, well saturated with lead-water and secured by bandages, should be applied. Internally, doses of Epsom-salts, of two ounces each, dissolved in half a pint of water, should be given until the bowels are acted upon. After the inflammation has subsided, to counteract the weakness which may follow, give a bottle of porter two or three times a day. OBSTRUCTIONS IN THE OESOPHAGUS. Choking in cattle is of common occurrence, in consequence of turnips, potatoes, carrots, or other hard substances, becoming lodged in the oesophagus, or gullet. These obstructions can sometimes be removed by careful manipulations with the hand; but, where this can not be accomplished, the flexible probang should be employed. This is a long India-rubber tube, with a whalebone stillet running through it, so as to stiffen it when in use. This instrument is passed down the animal's throat, and the offending substance is thus pushed down into the stomach. OPEN JOINTS. Opening of the joint generally results from accidents, from puncturing with sharp substances, from kicks, blows, etc. These injuries cause considerable nervous irritation in the system, and sometimes cause lock-jaw and death. _Treatment._--Close up the wound as speedily as possible. The firing-iron will sometimes answer the purpose very well. The author depends more upon the application of collodion--as recommended in his work upon "The Horse and His Diseases" for the same trouble--than upon any other remedy. It requires care in its application, in order to make it adhere firmly. Shoemakers'-wax, melted and applied, answers a very good purpose. PARTURITION. In natural labor--as has been suggested in a former part of this work--the aid of man is rarely required in bringing away the calf. But it not infrequently happens that, from malformation or wrong presentation, our assistance is required in order to deliver the animal. The brute force, which has been far too often heretofore resorted to, should no longer be tolerated, since the lives of many valuable animals have been sacrificed by such treatment. Very often, by gentle manipulation with the greased hand, the womb can be so dilated as to afford a comparatively easy exit for the _foetus_. If, however, the calf is presented wrong, it must be pushed back and placed in its proper position, if possible. In natural labor, the fore-legs, with the head lying between them, are presented; in which position--unless deformity, either in the _pelvis_ of the cow, or in the _foetus_, exists--the calf is passed with little difficulty, and without assistance. It sometimes happens that the head of the foetus is turned backward. When this happens, the attendant should at once strip himself to the waist, bathe his arms, and hands with a little sweet-oil, or lard, and introduce them into the _vagina_, placing a cord around both fore-feet, and then, pushing them back, search for the head, which is to be brought forward to its proper position. The feet are next to be brought up with it. No force should be used, except when the cow herself makes the effort to expel the calf; otherwise, more harm than good may be done. A case of this kind recently occurred in the author's practice, being the third within a year. The subject was a cow belonging to William Hance, Esq., of Bordentown, New Jersey. After she had been in labor for some twenty hours, he was called upon to see her. Upon inquiry, he found that several persons had been trying, without success, to relieve her. She was very much prostrated, and would, doubtless, have died within two or three hours, had no relief been afforded. The legs of the _foetus_ protruded as far as the knees; the head was turned backward, and with the body, pressed firmly into the _vagina_, so that it was impossible to return it, or to bring the head forward. The operation of embryotomy was, therefore, at once performed, by cutting away the right shoulder, which enabled the operator, with the aid of his appropriate hooks, to bring the head forward, when the calf came away without further trouble,--the whole operation not requiring fifteen minutes. The _uterus_ was then washed out, and the animal placed in as comfortable a position as possible, and a stimulating draught given, composed of two ounces of nitric ether, one ounce of tincture of opium, and a half pint of water. This was followed with a few doses of Fleming's tincture of aconite, ten drops in a little water, every few hours. In a few days the animal had entirely recovered. Occasionally, the head comes first, or the head and one leg. In such cases, a cord should be slipped around the jaw and leg, and these then pushed back, so as to allow the other leg to be brought up. When this cannot be done, the _foetus_ can, in most cases, be removed in the original position. Breech, side, back, and other presentations sometimes occur; in all of which instances, the _foetus_ must be turned in such a position that it can be brought away with as little trouble as possible. When this cannot be accomplished, the only resort is embryotomy, or cutting up of the _foetus_, which operation can only be safely performed by the qualified veterinary surgeon. Since writing the above, another case has occurred in the author's practice. The cow--belonging to Samuel Barton, Esq., near Bordentown, New Jersey--had been in labor some eighteen hours; upon an examination of the animal, the calf was found to be very much deformed, presenting backwards,--one of the hind-legs having been pulled off by the person or persons assisting her previous to the author's arrival. Finding it impossible to deliver her in the usual way, embryotomy was in this instance employed. By this means, after taking out the intestines, lungs, etc., of the _foetus_, and cutting away its hind-quarters, the fore-parts were brought away. The head presented a singular appearance; the under jaw was so twisted as to bring the front teeth on the side of the face; the spinal column or back-bone, was turned twice around, resembling a spiral string; the front legs were over the back; the ribs were much contorted; the hind-parts were as much deformed; and, taken altogether, the deformity was the most singular which has been brought under the author's observation. FREE MARTINS.--It has long been supposed by stockbreeders, that if a cow produce twins, one of which is a male and the other a female, the female is incapable of producing young, but that the male may be a useful animal for breeding purposes. Many instances have occurred when the twin sister of a bull has never shown the least desire for the male. This indifference to sexual commerce arises, doubtless, from the animal's being but imperfectly developed in the organs of generation. This fact has been established by the investigations of Mr. John Hunter, who had three of these animals slaughtered for anatomical examination. The result is thus reported: "The external parts were rather smaller than is customary in the cow. The _vagina_ passed on, as in the cow, to the opening of the _urethra_, and then it began to contract into a small canal, which passed on into the division of the _uterus_ into the two horns; each horn passed along the edge of the broad ligament laterally toward the _ovaria_. "At the termination of these horns were placed both the ovaries and the testicles. Both were nearly of the same size, which was about as large as a small nutmeg. To the _ovaria_, I could not find any Fallopian tube. "To the testicles were _vasa deferentia_, but they were imperfect. The left one did not come near the testicle; the right one only came close to it, but did not terminate in the body called the _epididymis_. They were both pervious and opened into the _vagina_, near the opening of the _urethra_. "On the posterior surface of the bladder, or between the _uterus_ and the bladder, were the two bags, called _vesiculae seminales_ in the male, but much smaller than they are in the bull. The ducts opened along with the _vasa deferentia_. This animal, then, had a mixture of all the parts, but all of them were imperfect." Well-authenticated cases have, however, occurred where the female has bred, and the offspring proved to be good milkers. There are several instances on record of cows' giving birth to three, four, and even five calves at a time. There were on exhibition, in 1862, at Bordentown, New Jersey, three free martins, two sisters and a brother, which were beautiful animals. These were from a cow belonging to Mr. Joab Mershon, residing on Biles Island, situated in the Delaware River, a short distance above Bordentown. They were calved November 1st, 1858, and were therefore nearly four years of age. They had never shown the least desire for copulation. Their aggregate weight was 4300 pounds. We extract the following from the London Veterinarian, for 1854:--"A cow, belonging to Mr. John Marshall, of Repton, on Wednesday last, gave birth to _five, live healthy calves_, all of which are, at the time I write, alive and vigorous, and have every appearance of continuing so. They are all nearly of a size, and are larger and stronger than could be supposed. Four of them are bull-calves. "The dam is by no means a large one, is eleven years old, of a mongrel breed, and has never produced more than one offspring at any previous gestation. I saw her two days after she had calved, at which time she was ruminating, and did not manifest any unusual symptoms of exhaustion. I may mention that the first four calves presented naturally; the fifth was a breech-presentation." CLEANSING.--The _placenta_, or after-birth, by which the _foetus_ is nourished while in embryo, should be removed soon after calving. Generally, it will come away without any assistance. This is what is called "cleansing after calving." When, however, it remains for some time, its function having been performed, it becomes a foreign body, exciting uterine contractions, and therefore injurious. The sooner, then, it is removed, the better for the animal as well as the owner. To accomplish this, the hand should be introduced, and, by pulling gently in various directions, it will soon yield and come away. Should it be allowed to remain, it rapidly decomposes, producing a low, feverish condition of the system, which greatly interferes with the general health of the animal. INVERSION OF THE UTERUS.--The _uterus_ is sometimes turned inside out after calving. This is, generally, the result of debility, or severe labor. The _uterus_ should be replaced as carefully as possible with the hands, care being taken that no dirt, straw, or other foreign substance adheres to it. Should it again be expelled, it would be advisable to quiet the system by the use of an anaesthetic, as chloroform, or--which is much safer--chloric ether. As soon as the animal is under the influence of this, the _uterus_ may be again replaced. The hind-quarters should be raised as high as possible, in order to favor its retention. The animal should have a little gruel and a bottle of porter given to her every five or six hours, and the _vulva_ should be bathed frequently with cold water. PHRENITIS. Inflammation of the brain is one of those dreadful diseases to which all animals are liable. It is known to the farmer as frenzy, mad staggers, etc. The active symptoms are preceded by stupor; the animal stubbornly stands in one position; the eyes are full, red, and fiery; respiration rapid; delirium soon succeeds; the animal, bellowing, dashes wildly about, and seems bent on mischief, rushing madly at every object which comes in its way. The causes of this disease are overwork in warm weather, a plethoric condition of the system, and too stimulating food. Prof. Gamgee, of the Edinburgh Veterinary College, relates a case resulting from the presence within the external _meatus_ of a mass of concrete cerumen, or wax, which induced inflammation of the ear, extending to the brain. _Treatment._--As this is attended with considerable risk, unless it is taken prior to the frenzied stage, bleeding almost to fainting should be resorted to, and followed by a brisk purge. Take one ounce of Barbadoes aloes, and ten to fifteen drops of Croton-oil; mix the aloes with one pint of water and the oil, using the mixture as a drench. One pound of Epsom-salts will answer the purpose very well, in cases where the aloes and oil cannot be readily obtained. Application of bags of broken ice to the head, is very beneficial. Spirits of turpentine, or mustard, together with spirits of hartshorn and water should be well rubbed in along the spine, from the neck to the tail. PLEURISY. This is an inflammation of the _pleura_, or the serous membrane which lines the cavity of the chest, and which is deflected over the lungs. Inflammation of this membrane rarely occurs in a pure form, but is more generally associated with inflammation of the tissue of the lungs. If this disease is not attended to at an early period, its usual termination is in hydrothorax, or dropsy of the chest. The same causes which produce inflammation of the lungs, of the bronchia, and of the other respiratory organs, produce also pleurisy. _Symptoms._--The respiration is quick, short, and painful; pressure between the ribs produces much pain; a low, short, painful cough is present; the respiratory murmur is much diminished,--in fact, it is scarcely audible. This condition is rapidly followed by effusion, which may be detected from the dullness of the sounds, on applying the ear to the lower part of the lungs. The febrile symptoms disappear; the animal for a few days appears to improve, but soon becomes weak, languid, and often exhausted from the slightest exertion. _Treatment._--The same treatment in the early stage is enjoined as in inflammatory pneumonia, which the reader will consult--counter-irritation and purgatives. Bleeding never should be resorted to. When effusion takes place, it is necessary to puncture the sides with a trochar, and draw away the fluid, giving internally one of the following purges three times a day: rosin, eight ounces; saltpetre, two ounces, mix, and divide into eight powders. Half-drachm doses of the iodide of potash, dissolved in water, to be given three times daily, will be found useful in this disease. PLEURO-PNEUMONIA. This disease, as its name implies, is an inflammatory condition of the lungs and the _pleura_, or the enveloping membrane of the lungs and the lining membrane of the chest. It is sometimes called contagious, infectious, and epizooetic pleuro-pneumonia,--contagious or infectious, from its supposed property of transmission from the diseased to the healthy animal. [Illustration: TAKING AN OBSERVATION.] A contagious character the author is not ready to assign to it,--contagious, as he understands it, being strictly applicable to those diseases which depend upon actual contact with the poison that it may be communicated from one animal to another. This does not necessarily imply the actual touching of the animals themselves; for it may be communicated from the poison left in the trough, or other places where the diseased animal has been brought in contact with some object, as is often the case in glanders in the horse; the matter discharged from the nose, and left upon the manger, readily communicating that disease to healthy animals coming in contact with it. Contagious diseases, therefore, travel very slowly, starting, as they do, at one point, and gradually spreading over a large district, or section of country. This disease is, however, regarded by the author as infectious; by which term is meant that it is capable of being communicated from the diseased to the healthy animal through the medium of the air, which has become contaminated by the exhalations of poisonous matter. The ability to inoculate other animals in this way is necessarily confined to a limited space, sometimes not extending more than a few yards. Infectious diseases, accordingly, spread with more rapidity than contagious ones, and are, consequently, more to be dreaded; since we can avoid the one with comparatively little trouble, while the other often steals upon us when we regard ourselves as beyond its influence, carrying death and destruction in its course. The term by which this disease is known, is a misnomer. Pleuro-pneumonia proper is neither a contagious, nor an infectious disease; hence, the denial of medical men that this so-called pleuro-pneumonia is a contagious, or infectious disease, has been the means of unnecessarily exposing many animals to its poisonous influence. In the _Recueil de Medecine Veterinaire_, for 1833, will be found a very interesting description of this fatal malady. The author, M. Lecoy, Assistant Professor at the Veterinary School of Lyons, France, says: "There are few districts in the _arrondissement_ of Avesnes where more cattle are fattened than in that of Soire-le-Chateau. The farmers being unable to obtain a sufficient supply of cattle in the district, are obliged to purchase the greater part of them from other provinces; and they procure a great number for grazing from Franche Comte. The cattle of this country are very handsome; their forms are compact; they fatten rapidly; and they are a kind of cattle from which the grazer would derive most advantage, were it not that certain diseases absorb, by the loss of some of the animals, the profits of the rest of the herd. Amongst the diseases which most frequently attack the cattle which are brought from the North, there is one very prevalent in some years, and which is the more to be dreaded as it is generally incurable; and the slaughter of the animal, before he is perceptibly wasted, is the only means by which the farmer can avoid losing the whole value of the beast. "This disease is chronic pleuro-pneumonia. The symptoms are scarcely recognizable at first, and often the beast is ill for a long time without its being perceived. He fattens well, and when he is slaughtered the owner is astonished to find scarcely half of the lungs capable of discharging the function of respiration. When, however, the ox has not sufficient strength of constitution to resist the ravages of disease, the first symptom which is observed is diminution, or irregularity of appetite. Soon afterwards, a frequent, dry cough is heard, which becomes feeble and painful as the disease proceeds. The dorso-lumbar portion of the spine (loins) grows tender; the animal flinches when the part is pressed upon, and utters a peculiar groan, or grunt, which the graziers regard as decisive of the malady. "Quickly after this, the movements of the flanks become irregular and accelerated, and the act of respiration is accompanied by a kind of balancing motion of the whole body. The sides of the chest become as tender as the loins, or more so; for the animal immediately throws himself down, if pressed upon with any force. The elbows become, in many subjects, more and more separated from the sides of the chest. The pulse is smaller than natural, and not considerably increased. The muzzle is hot and dry, alternately. The animal lies down as in a healthy state, but rumination is partially or entirely suspended. The _faeces_ are harder than they should be; the urine is of its natural color and quantity; the mouth is often dry; and the horns and ears retain their natural temperature. "This first stage of the disease sometimes continues during a month, or more, and then, if the animal is to recover, or at least, apparently so, the symptoms gradually disappear. First of all, the appetite returns,
