_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 s.c.r.o.t.u.m. 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 s.c.r.o.t.u.m in the hand, between the t.e.s.t.i.c.l.es 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 t.e.s.t.i.c.l.e, and of sufficient length to admit of its escape. The t.e.s.t.i.c.l.e immediately bursts from its bag, and is seen hanging by its cord.
The careless or brutal operator now firmly ties a piece of small string around the cord, and having thus stopped the circulation, cuts through the cord, half an inch below the ligature, and removes the t.e.s.t.i.c.l.e. He, however, who has any feeling for the poor animal on which he is operating, considers that the only use of the ligature is to compress the blood-vessels and prevent after-hemorrhage, and, therefore, saves a great deal of unnecessary torture by including them alone in the ligature, and afterwards dividing the rest of the cord. The other t.e.s.t.i.c.l.e is proceeded with in the same way and the operation is complete. The length of the cord should be so contrived that it will immediately retract, or be drawn back, into the s.c.r.o.t.u.m, but not higher, while the ends of the string hang out through the wound. In the course of about a week, the strings will usually drop off, and the wounds will speedily heal. There will rarely be any occasion to make any application to the s.c.r.o.t.u.m, except fomentation of it, if much swelling should ensue.
A few, whose practice cannot be justified, seize the t.e.s.t.i.c.l.e as soon as it escapes from the bag, and, pulling violently, break the cord and tear it out. It is certain that when a blood-vessel is thus ruptured, it forcibly contracts, and very little bleeding follows; but if the cord breaks high up, and retracts into the belly, considerable inflammation has occasionally ensued, and the beast has been lost.
The application of _torsion_--or the twisting of the arteries by a pair of forceps which will firmly grasp them--has, in a great degree, superseded every other mode of castration, both in the larger and the smaller domesticated animals. The spermatic artery is exposed, and seized with the forceps, which are then closed by a very simple mechanical contrivance; the vessel is drawn a little out from its surrounding tissue, the forceps are turned around seven or eight times, and the vessel liberated. It will be found to be perfectly closed; a small knot will have formed on its extremity; it will retract into the surrounding surface, and not a drop more of blood will flow from it; the cord may then be divided, and the bleeding from any little vessel arrested in the same way. Neither the application of the hot iron, nor of the wooden clamps, whether with or without caustic, can be necessary in the castration of the calf.
A new instrument was introduced in France, some few years since, for this purpose, called the _acraseur_,--so constructed as to throw a chain over the cord, which is wound up by means of a screw working upon the chain, and at the same time the cord is twisted off. No bleeding follows this method of operating.
This instrument is constructed upon the same principle as the _acraseur_ for use in the human family, for the removal of hemorrhoids, etc., the dimensions of the two only varying.
The advantages resulting from the use of this instrument over all other methods are, that the parts generally heal within a week,--the operation is not so painful to the animal,--it is less troublesome to the operator,--also to the owner of the animal,--and lastly, it is a safer and more scientific operation. Its success in France soon gave it a reputation in England, and recently it has been introduced by the author into this country, and with the best results. Contractors, hearing of the success attending this new mode of operating, have visited him from all parts of the country to witness its performance, and not one has returned without leaving an order for this instrument,--so well convinced have they been of its decided superiority over all other methods.
TRACHEOTOMY.
In consequence of the formation of tumors about the throat in cattle, from inflammation of the parotid gland, blain, etc., so characteristic of this species of animals, it sometimes becomes necessary to perform this operation in order to save their lives. It never fails to give instant relief.
After the animal has been properly secured,--which is done by an a.s.sistant"s holding the nose with one hand, and one of the horns with the other,--the operator draws the skin tight over the windpipe with the thumb and fingers of his left hand; then, with the scalpel in his right, cuts through the skin, making an incision about three inches long, dissecting up the skin on each side, which brings the _trachea_, or windpipe, in full view. He then cuts out a piece of the cartilaginous rings, about two inches long and about half an inch wide. This simple operation has saved the lives of very many valuable animals. The wound readily heals, and seldom leaves any perceptible blemish, if the work is properly performed.
SPAYING.
To secure a more uniform flow and a richer quality of milk, cows are sometimes spayed, or castrated. The milk of spayed cows is pretty uniform in quality; and this quality will be, on an average, a little more than before the operation was performed. In instances where the results of this operation have been carefully noted,--and the operation is rarely resorted to in this country, in comparison with the custom in France and other continental countries,--the quality of the milk has been greatly improved, the yield becoming regular for some years, and varying only in accordance with the difference in the succulence of the food.
The proper time for spaying is about five or six weeks after calving, or at the time when the largest quant.i.ty of milk is given. There seems to be some advantages in spaying for milk and b.u.t.ter dairies, where attention is not paid to the raising of stock. The cows are more quiet, never being liable to returns of seasons of heat, which always more or less affect the milk, both in quant.i.ty and quality. They give milk nearly uniform in these respects, for several years, provided the food is uniformly succulent and nutritious. Their milk is influenced like that of other cows, though to a less extent, by the quality and quant.i.ty of food; so that in winter, unless the animal is properly attended to, the yield will decrease somewhat, but will rise again as good feed returns. This uniformity for the milk-dairy is of immense advantage. Besides, the cow, when old and inclined to dry up, takes on fat with greater rapidity, and produces a juicy and tender beef, superior, at the same age, to that of the ox.
The following method of performing this operation is sanctioned by the practice of eminent veterinary surgeons in France:--
Having covered the eyes of the cow to be operated upon, she is placed against a wall, provided with five rings firmly fastened and placed as follows: the first corresponds to the top of the withers; the second, to the lower anterior part of the breast; the third is placed a little distance from the angle of the shoulder; the fourth is opposite to the anterior and superior part of the lower region; and the fifth, which is behind, answers to the under-part of the b.u.t.tocks. A strong a.s.sistant is placed between the wall and the head of the animal, who firmly holds the left horn in his left hand, and with his right, the muzzle, which he elevates a little. This done, the end of a long and strong-plaited cord is pa.s.sed, through the ring which corresponds to the lower part of the breast, and fastened; the free end of the cord is brought along the left flank, and through the ring which is below and in front of the withers.
This is brought down along the breast behind the shoulder and the angle of the fore-leg in order to pa.s.s it through the third ring; then it must be pa.s.sed around against the outer angle of the left hip, and fastened after having been drawn tightly to the posterior ring, by a simple bow-knot.
The cow being thus firmly fixed to the wall, a cord is fastened by a slip-noose around her hocks, to keep them together in such a manner that she cannot kick the operator, the free end of the cord and the tail being held by an a.s.sistant. The cow thus secured cannot, during the operation, move forward, nor lie down, and the operator has all the ease desirable, and is protected from accident.
The operator next--placed opposite to the animal"s left flank, with his back turned a little toward the head of the animal--cuts off the hair which covers the hide in the middle of the flanks, at an equal distance between the back and hip, for the s.p.a.ce of thirteen or fourteen centimetres in circ.u.mference (the French _centimetre_ is rather more than thirty-nine one hundredths of an inch); a convex bistoury is placed, opened, between his teeth, the edge out, the joints to the left; then, with both hands, he seizes the hide in the middle of the flank, and forms of it a wrinkle of the requisite elevation, running lengthwise of the body. The a.s.sistant seizes with his right hand the right side of this wrinkle; the operator takes the bistoury and cuts the wrinkle, at one stroke, through the middle; the wrinkle having been suffered to go down, a separation of the hide is presented, of sufficient length to admit the introduction of the hand; the edges of the hide are separated with the thumb and fore-finger of the left hand, and in like manner the abdominal muscles are cut through, for the distance of a centimetre from the lower extremity of the incision made in the hide,--the _iliac_ slightly obliquely, and the _lumbar_ across; a puncture of the peritoneum, at the upper extremity of the wound, is then made with the straight bistoury; the b.u.t.toned bistoury is then introduced, and moved obliquely from above to the lower part, up to the termination of the incision made in the abdominal muscles.
The flank being opened, the right hand is introduced into the abdomen, and directed along the right side of the cavity of the pelvis, behind the paunch, and underneath the r.e.c.t.u.m, to the matrix; after the position of these viscera is ascertained, the organs of reproduction, or ovaries, are searched for, which are at the extremity of the matrix; when found, they are seized between the thumb and fore-finger, detached completely from the ligaments which keeps them in their place, and by a light pull, the cord and the vessels, the uterine or Fallopian tube, are separated at their place of union with the ovarium, by means of the nails of the thumb and fore-finger, which present themselves at the point of touch, thus breaking the cord and bringing away the ovary.
The hand is again introduced into the abdominal cavity, and the remaining ovaries brought away in like manner. A suture is then placed of three or four double threads, waxed at an equal distance, and at two centimetres, or a little less, from the lips of the wound, pa.s.sing it through the divided tissues; a movement is made from the left hand with the piece of thread; having reached that point, a fastening is made with a double knot, the seam placed in the intervals of the thread from the right, and as the lips of the wound are approached, a fastening is effected by a simple knot, with a bow, care being taken not to close too tightly the lower part of the seam, in order to allow the suppuration, which may be established in the wound, to escape. The wound is then covered up with a pledget of lint, kept in its place by three or four threads pa.s.sed through the st.i.tches, and the operation is complete.
It happens, sometimes, that in cutting the muscles before mentioned, one or two of the arteries are severed. Should much blood escape, a ligature must be applied before opening the peritoneal sac; since, if this precaution is omitted, blood will escape into the abdomen, which may occasion the most serious consequences.
For the first eight days succeeding, the animal should have a light diet, and a soothing, lukewarm draught; if the weather should be cold, cover with a woollen covering. She must be prevented from licking the wound, and from rubbing it against other bodies. The third day after the operation, bathe morning and evening about the wound with water of mallows lukewarm, or anoint it with a salve of hog"s lard, and administer an emollient glyster during three or four days.
Eight days after the operation, take away the bandage, the lint, the fastenings, and the thread. The wound is at that time, as a general thing, completely cicatrized. Should, however, some slight suppuration exist, a slight pressure must be used above the part where it is located, so as to cause the pus to leave, and if it continues more than five or six days, emollients must be supplied by alcolized water, or chloridized, especially in summer. The animal is then to be brought back gradually to her ordinary nourishment.
In some cows, a swelling of the body is observable a short time after having been spayed, attributable to the introduction of cold air into the abdomen during the operation; but this derangement generally ceases within twenty-four hours. Should the contrary occur, administer one or two sudorific draughts, such as wine, warm cider, or a half-gla.s.s of brandy, in a quart of warm water,--treatment which suffices in a short time to restore a healthy state of the belly,--the animal at the same time being protected by two coverings of wool.
The only precaution, in the way of management, to be observed as a preparative for the operation is, that on the preceding evening not so copious a meal should be given. The operation should also be performed in the morning before the animal has fed, so that the operator may not find any obstacle from the primary digestive organs, especially the paunch, which, during its state of ordinary fullness, might prevent operating with facility.
The advantages of spaying milch-cows are thus summed up by able French writers: First, rendering permanent the secretion of milk, and having a much greater quant.i.ty within the given time of every year; second, the quality of milk being improved; third, the uncertainty of, and the dangers incident to, breeding being, to a great extent, avoided; fourth, the increased disposition to fatten even when giving milk freely, or when, from excess of age or from accidental circ.u.mstances, the secretion of milk is otherwise checked; fifth, the very short time required to produce a marketable condition; and sixth, the meat of spayed cattle being of a quality superior to that of ordinary cattle.
This operation would seem to have originated in this country. The London Veterinary Journal of 1834 contains the following, taken from the United States Southern Agriculturist:--"Some years since, I pa.s.sed a summer at Natchez, and put up at a hotel there, kept by Mr. Thomas Winn. During the time that I was there I noticed two remarkably fine cows, which were kept constantly in the stable, the servant who had charge of the horses, feeding them regularly three times a day with green guinea gra.s.s, cut with a sickle. These cows had so often attracted my attention, on account of the great beauty of their form, and deep red color, the large size of their bags, and the high condition in which they were kept, that I was at length induced to ask Mr. Winn to what breed of cattle they belonged, and his reasons for keeping them constantly in the stable in preference to allowing them to run in the pasture, where they could enjoy the benefit of air and exercise, and at the same time crop their own food, and thereby save the labor and trouble of feeding them? Mr.
Winn, in reply to these inquiries, stated that the two cows which I so much admired were of the common stock of the country, and he believed, of Spanish origin; but they were both spayed cows, and that they had given milk either two or three years. Considering this a phenomenon (if not in nature at least in art), I made further inquiries of Mr. Winn, who politely entered into a very interesting detail, communicating facts which were as extraordinary as they were novel. Mr. Winn, by way of preface, observed that he, in former years, had been in the habit of reading English magazines, which contained accounts of the plowing-matches which were annually held in some of the southern counties of England, performed by cattle, and that he had noticed that the prizes were generally adjudged to the plowman who worked with spayed heifers; and although there was no connection between that subject and the facts which he should state, it was, nevertheless, the cause that first directed his mind into the train of thought and reasoning which finally induced him to make the experiments, which resulted in the discovery of the facts which he detailed, and which I will narrate as accurately as my memory will enable me to do it, after the lapse of more than twenty years. Mr. Winn"s frequent reflections had (he said) led him to the belief "that if cows were spayed soon after calving, and while in a full flow of milk, they would continue to give milk for many years without intermission, or any diminution of quant.i.ty, except what would be caused by a change from green to dry, or less succulent food." To test this hypothesis, Mr. Winn caused a very good cow, then in full milk, to be spayed. The operation was performed about one month after the cow had produced her third calf; it was not attended with any severe pain, or much or long continued fever. The cow was apparently well in a few days, and very soon yielded her usual quant.i.ty of milk, and continued to give freely for several years without any intermission or diminution in quant.i.ty, except when the food was scarce and dry; but a full flow of milk always came back upon the return of a full supply of green food. This cow ran in the Mississippi low grounds or swamp near Natchez, got cast in deep mire, and was found dead. Upon her death, Mr.
Winn caused a second cow to be spayed. The operation was entirely successful. The cow gave milk constantly for several years, but in jumping a fence stuck a stake in her bag, that inflicted a severe wound, which obliged Mr. Winn to kill her. Upon this second loss, Mr. Winn had two other cows spayed, and, to prevent the recurrence of injuries from similar causes with those which had occasioned him the loss of the first two spayed cows, he resolved to keep them always in the stable, or some safe enclosure, and to supply them regularly with green food, which that climate throughout the greater part of, if not all, the year enabled him to procure. The result, in regard to the last two spayed cows, was, as in the case of the first two, entirely satisfactory, and fully established, as Mr. Winn believed, the fact, that the spaying of cows, while in full milk, will cause them to continue to give milk during the residue of their lives, or until prevented by old age. When I saw the last two spayed cows it was, I believe, during the third year that they had constantly given milk after they were spayed. The character of Mr.
Winn (now deceased) was highly respectable, and the most entire confidence could be reposed in the fidelity of his statements; and as regarded the facts which he communicated in relation to the several cows which he had spayed, numerous persons with whom I became acquainted, fully confirmed his statements."
In November 1861, the author was called to perform this operation upon the short-horn Galloway cow, Josephine the Second, belonging to Henry Ingersoll, Esq., of this city. This cow was born May 8th, 1860. The morning was cold and cloudy. About ten o"clock the cow was cast, with the a.s.sistance of R. McClure, V.S., after which she was placed under the influence of chloric ether. He then made an incision, about five inches in length, through the skin and walls of the abdomen, midway between the pelvis bone and the last rib on the left side, pa.s.sing in his right hand, cutting away the ovaries from the Fallopian tubes with the thumbnail. The opening on the side was then closed by means of the interrupted suture. The animal recovered from the influence of the anaesthetic in about fifteen minutes, when she was allowed to rise, and walk back to her stall.
Upon the morning of the second day succeeding the operation, the animal was visited and found to be in good spirits, apparently suffering very little pain or inconvenience from the operation, and the wound healing nicely.
Since that time, he has operated upon some twenty cows, all of which, with a single exception, have thus far proved satisfactory.
Several of these cows are under the direction of a committee from the Philadelphia Society for promoting Agriculture, whose duty it is to have a daily record kept of each cow"s yield of b.u.t.ter and milk, for one year from the time of spaying. Their report will be perused by the agricultural community with much interest.
The author"s own experience will not justify him in speaking either in favor of, or against, this operation; as sufficient time has not as yet elapsed to satisfy him as to its relative advantages and disadvantages.
He, however, regards the operation as comparatively safe. The French estimate the loss at about fifteen per cent., and the gain at thirty per cent. Of those upon which he has operated, not a single animal died.
A LIST OF MEDICINES USED IN TREATING CATTLE.
The medicines used in the treatment of the diseases of cattle, are essentially the same as those in vogue for the diseases of the human being and the horse,--the only difference being in their combination and the quant.i.ties administered.
ABSORBENTS.--Medicines which destroy acidities in the stomach and bowels; such as chalk, magnesia, etc.
ALTERATIVES.--Medicines which restore the healthy functions of secretion, by gradually changing the morbid action in an impaired const.i.tution. Those in most common use are aethiops mineral, antimony, rosin, sulphur, etc., which form the princ.i.p.al ingredients in all condition-powders, and are chiefly useful in diseases of the skin, such as hide-bound, mange, surfeit, etc.
ALTERATIVE POWDER.--Sulphur pulverized, one pound; black antimony, one half a pound; nitrate of pota.s.sa, four ounces; sulphate of iron, one half a pound; linseed meal, one pound; mix well; dose, one half an ounce, night and morning.
ANTACIDS.--Agents which neutralize, by their chemical action, acids in the stomach; as ammonia, carbonate of pota.s.sa, chalk, lime-water, magnesia, and soda.
ANTHELMINTICS.--Remedies used for the expulsion of worms from the stomach and intestines. These may act chemically or by their cathartic operation. The most reliable are aethiops mineral, nux vomica, preparations of mercury, wormwood, etc.
