The American Reformed Cattle Doctor Part 24

In a subsequent number of the same work we find the subject resumed; from which able production we select the following:--

"The suppression of perspiration has at all times been thought to have a good deal to do with the production of disease. Without doubt this has been exaggerated. But, allowing this exaggeration, is it not admitted by all pract.i.tioners that causes which act through the medium of the skin are susceptible, in sufficient degree, of being appreciated in the circ.u.mstances ushering in the development of very many diseases, especially those characterized by any active flux of the visceral organs? For example, is it not an incontestable pathological fact, that catarrhal, bronchial, pulmonic, and pleuritic affections, congestions of the most alarming description in the vascular abdominal system of the horse, inflammation of the peritoneum and womb following labor, catarrhal inflammations of the bowels, even congestions of the feet, &c., derive their origin, in a great number of instances, from cold applied to the skin in a state of perspiration? What happens in the organism after the application of such a cause? Is its effect instantaneous? Let us see. Immediately on the repercussive action of cold being felt by the skin, the vascular system of internal parts finds itself filled with repelled blood. Though this effect, however, be simply hydrostatic, the diseased phenomena consecutive on it are far otherwise.

"It is quite certain that, in the immense system of communicating vessels forming the circulating apparatus, whenever any large quant.i.ty of blood flows to any one particular part of the body, the other vessels of the system must be comparatively empty.[14] The knowledge of this organic hydrostatic fact it is that has given origin to the use of revulsives under their various forms, and we all well know how much service we derive from their use.

"But in what does this diseased condition consist? Whereabouts is it seated?

"The general and undefined mode it has of showing its presence in the organism points this out. Immediately subsequent to the action of the cause, the actual seat of the generative condition of the disease about to appear is the blood; this fluid it is which, having become actually modified in its chemical compositions under the influence of the cause that has momentarily obstructed the cutaneous exhalations, carries about every where with it the disordered condition, and ultimately giving rise, through it, to some local disease, as a sort of eruptive effort, a.n.a.logous in its object, but often less salutary in its effect; owing to the functional importance of the part attacked, to the external eruptions produced by the presence in the blood of virus, which alters both its dynamic and chemical properties.

"But what is the nature of this alteration? In this case, every clew to the solution of this question fails us. We know well, when the experiment is designedly prolonged, the blood grows black, as in _asphyxia_, (loss of pulse,) through the combination with it of carbonic acid, whose presence is opposed to the absorption of oxygen. But what relation is there between this chemical alteration of blood here and the modifications in composition it may undergo under the influence of instantaneous suppression, but not persistent, of the cutaneous exhalations and secretions? The experiments of Dr. Fourcault tend, on the whole, to explain this. His experiments discover the primitive form and almost the nature of the alteration the blood undergoes under the influence of the cessation of the functions of the skin. They demonstrate that under these conditions the regularity of the course of this fluid is disturbed--that it has a tendency to acc.u.mulate and stagnate within the internal organs: witness the abdominal pains so frequently consequent on the application of plasters upon the skin, and the congestions of the abdominal and pulmonary vascular systems met with almost always on opening animals which have been suffocated through tar or pitch plasters.

"They prove, in fact, the thorough apt.i.tude of impression of the nervous system to blood altered in its chemical properties, while they afford us an explication of the phenomena of depression, and muscular prostration, and weakness, which accompany the beginning of disease consecutive on the operation of cold.

"How often do we put a stop to the ulterior development of disease by restoring the function of the skin by mere [dry] friction, putting on thick clothing, exposing to exciting fumigation, applying temporary revulsives in the shape of mustard poultices, administering diffusible stimuli made warm in drenches, trying every means to force the skin, and so tend, by the reestablishment of its exhalent functions, to permit the elimination of blood saturated with carbonic matters opposed to the absorption by it of oxygen!

"Do we not here perceive, so to express ourselves, the evil enter and depart through the skin?

"M. Roche-Lubin gives an account of some lambs which were exposed, after being shorn, to a humid icy cold succeeding upon summer heat. These animals all died; and their post mortem examination disclosed nothing further than a blackened condition of blood throughout the whole circulating system, with stagnation in some organs, such as the liver, the spleen, or abdominal vascular system.

"From the foregoing disclosures, which might be multiplied if there was need of it, we learn that the regularity or perversion of the functions of the skin exercises an all-powerful influence over the conservation or derangement of the health, and that very many diseases can be traced to no other origin than the interruption, more or less, of these functions."

These remarks are valuable, inasmuch as they go to prove the importance, in the treatment of disease, of a restoration of the lost function. Our system of applying friction, warmth, and moisture to the external surface, in all cases of internal disease, here finds, in the authors just quoted, able advocates.

FOOTNOTE:

[14] What a destructive system, then, must blood-letting be, which proposes to supply this deficiency in the empty vessels by opening a vein and suffering the contents of the overcharged vessels to fall to the ground! If the blood abstracted from the full veins could be returned into those "empty" ones, then there would be some sense in blood-letting.

SPAYING COWS.

The castration of cows has been practised for several years in different parts of the world, with such remarkable success, that no one will doubt there are advantages to be derived from it. For the benefit of those who may have doubts on this subject, we give the opinions of a committee appointed by the Rheims Academy to investigate the matter.

"To the question put to the committee--

"1st. Is the spaying of cows a dangerous operation?

"The answer is, This operation, in itself, involves no more danger than many others of as bold a character, (as puncture of the rumen,) which are performed without accident by men even strangers to the veterinary art. Two minutes suffice for the extraction of the ovaries; two minutes more for suturing the wound.

"2dly. Will not the spaying of cows put an end to the production of the species?

"Without doubt, this is an operation which must be kept within bounds.

It is in the vicinity of large towns that most benefit will be derived from it, where milk is most generally sought after, and where pasturage is scanty, and consequently food for cows expensive. On this account it is not the practice to raise calves about the environs of Paris. Indeed, at Cormenteul, near Rheims, out of one hundred and forty-five cows kept, not more than from ten to fifteen calves are produced yearly.

"3dly. Is spaying attended with amelioration of the quality of the meat?

"That cows fatten well after being spayed is an incontestable fact, long known to agriculturists.

"4thly. Does spaying prolong the period of lactation, and increase the quant.i.ty of milk?

"The cow will be found to give as much milk after eighteen months as immediately after the operation; and there was found in quant.i.ty, in favor of the spayed cows, a great difference.

"5thly. Is the quality of the milk ameliorated by spaying?

"To resolve this question, we have thought proper to make an appeal to skilful chemists resident in the neighborhood; and they have determined that the milk abounds more by one third in cheese and b.u.t.ter than that of ordinary cows."

Mr. Percival says, "No person hesitates to admit the advantages derivable from the castration of bulls and stallions. I do not hesitate to aver, that equal, if not double, advantages are to be derived from the same operation when performed on cows."

"It is to America we are indebted for this discovery. In 1832, an American traveller, a lover of milk, no doubt, asked for some of a farmer at whose house he was. Surprised at finding at this farm better milk than he had met with elsewhere, he wished to know the reason of it.

After some hesitation, the farmer avowed, that he had been advised to perform on his cows the same operation as was practised on the bulls.

The traveller was not long in spreading this information. The Veterinary Society of the country took up the discovery, when it got known in America. The English--those ardent admirers of beefsteaks and roast beef--profited by the new procedure, as they know how to turn every thing to account, and at once castrated their heifers, in order to obtain a more juicy meat.

"The Swiss, whose princ.i.p.al employment is agricultural, had the good fortune to possess a man distinguished in his art, who foresaw, and was anxious to realize, the advantages of castrating milch cows. M. Levrat, veterinary surgeon at Lausanne, found in the government of his country an enlightened a.s.sistant in his praiseworthy and useful designs, so that, at the present day, instructions in the operation of spaying enter into the requirements of the programme of the professors of agriculture, and the gelders of the country are not permitted to exercise their calling until they have proved their qualifications on the same point."--_London Vet._ p. 274, 1850.

For additional evidence in favor of spaying, see Albany Cultivator, p.

195, vol. vi.

We have conversed with several farmers in this section of the United States, and find, as a general thing, that they labor under the impression that spaying is chiefly resorted to with a view of fattening cattle for the market. We have, on all occasions, endeavored to correct this erroneous conclusion, and at the same time to point out the benefits to be derived from this practice. The quality of the milk is superior, and the quant.i.ty is augmented. Many thousands of the miserable specimens of cows, that the farmer, with all his care, and having, at the same time an abundance of the best kind of provender, is unable to fatten, might, after the operation of spaying, be easily fattened, and rendered fit for the market; or, if they shall have had calves, they may be made permanent, and, of course, profitable milkers.

If a cow be in a weak, debilitated state, or, in other words, "out of condition," she may turn out to be a source of great loss to the owner.

In the first place, her offspring will be weak and inefficient; successive generations will deteriorate; and if the offspring be in a close degree of relationship, they will scarcely be worth the trouble of rearing. The spaying of such a cow, rather than she shall give birth to weak and worthless offspring, would be a great blessing; for then one of the first causes of degeneracy in live stock will have been removed.

Again, a cow in poor condition is a curse to the farmer; for she is often the medium through which epidemics, infectious diseases, puerperal fever, &c., are communicated to other stock. If there are such diseases in the vicinity, those in poor flesh are sure to be the first victims; and they, coming in contact with others laboring under a temporary indisposition, involve them in the general ruin. If prevention be cheaper than cure,--and who doubts it?--then the farmer should avail himself of the protection which spaying seems to hold out.

OPERATION OF SPAYING.

The first and most important object in the successful performance of this operation is to secure the cow, so that she shall not injure herself, nor lie down, nor be able to kick or injure the operator. The most convenient method of securing the cow is, to place her in the trevis;[15] the hind legs should then be securely tied in the usual manner: the band used for the purpose of raising the hind quarters when being shod must be pa.s.sed under the belly, and tightened just sufficient to prevent the animal lying down. Having secured the band in this position, we proceed, with the aid of two or more a.s.sistants, in case the animal should be irritable, to perform the operation. And here, for the benefit of that portion of our readers who desire to perform the operation _secundum artem_, we detail the method recommended by Morin, a French veterinary surgeon; although it has been, and can again be, performed with a common knife, a curved needle, and a few silken threads to close the external wound. The author is acquainted with a farmer, now a resident of East Boston, who has performed this operation with remarkable success, both in this country and Scotland, with no other instruments than a common shoemaker's knife and a curved needle. The fact is, the ultimate success of the operation does not depend so much on the instruments as on the skill of the operator. If he is an experienced man, understands the anatomy of the parts, and is well acquainted, by actual experience, with the nature of the operation, then the instruments become a matter of taste. The best operators are those who devote themselves entirely to the occupation. (See Mr. Blane's account of his "first essay in firing," p. 85, note.) Morin advises us to secure the cow, by means of five rings, to the wall. (See Albany Cultivator, vol. vi. p. 244, 1850.) "The cow being conveniently disposed of, and the instruments and appliances,--such as curved scissors, upon a table, a convex-edged bistoury, a straight one, and one b.u.t.toned at the point, suture needle filled with double thread of desired length, pledgets of lint of appropriate size and length, a ma.s.s of tow (in pledgets) being collected in a shallow basket, held by an a.s.sistant,--we place ourselves opposite to the left flank, our back turned a little towards the head of the animal; we cut 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; this done, we take the convex bistoury, and place it open between our teeth, the edge out, the point to the left; then, with both hands, we seize the hide in the middle of the flank, and form of it a wrinkle of the requisite elevation, and running lengthwise of the body.

"We then direct an a.s.sistant to seize, with his right hand, the right side of this wrinkle. We then take the bistoury, and cut 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 enable us to introduce the hand; thereupon we separate the edges of the hide with the thumb and fore finger of the left hand, and, in like manner, we cut through the abdominal muscles, the iliac, (rather obliquely,) and the lumbar, (cross,) for a distance of a centimetre from the lower extremity of the incision made in the hide: this done, armed with the straight bistoury, we make a puncture of the peritoneum, at the upper extremity of the wound; we then introduce the b.u.t.toned bistoury, and we move it obliquely from above to the lower part up to the termination of the incision made in the abdominal muscles. The flank being opened, we introduce the right hand into the abdomen, and direct it along the right side of the cavity of the pelvis, behind the paunch and underneath the r.e.c.t.u.m, where we find the horns of the uterus; after we have ascertained the position of these viscera, we search for the ovaries, which are at the extremity of the _cornua_, or horns, (fallopian tubes,) and when we have found them, we seize them between the thumb and fore finger, detach them completely from the ligaments that keep them in their place, pull lightly, separating the cord, and the vessels (uterine or fallopian tubes) at their place of union with the ovarium, by means of the nails of the thumb and fore finger, which presents itself at the point of touch; in fact, we break the cord, and bring away the ovarium.

"We then introduce again the hand in the abdominal cavity, and we proceed in the same manner to extract the other ovarium.

"This operation terminated, we, by the a.s.sistance of a needle, place a suture 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, we move from the left hand with the piece of thread; having reached that point, we fasten with a double knot; we place the seam in the intervals of the thread from the right, and as we approach the lips of the wound, we fasten by a simple knot, being careful not to close too tightly the lower part of the seam, so that the suppuration, which may be established in the wound, may be able to escape.

"The operation effected, we cover up the wound with a pledget of lint, kept in its place by three or four threads pa.s.sed through the st.i.tches, and all is completed.

"It happens, sometimes, that in cutting the muscles of which we have before spoken, we cut one or two of the arteries, which bleed so much that there is necessity for a ligature before opening the peritoneal sac, because, if this precaution be omitted, blood will escape into the abdomen, and may occasion the most serious consequences."

The best time for spaying cows, with a view of making them permanent milkers, is between the ages of five and seven, especially if they have had two or three calves. If intended to be fattened for beef, the operation should not be performed until the animal has pa.s.sed its second year, nor after the twelfth.

We usually prepare the animal by allowing a scalded mash every night, within a few days of the operation. The same precaution is observed after the operation.

If, after the operation, the animal appears dull and irritable, and refuses her food, the following drink must be given:--

Valerian, 2 ounces.
