This is a disease peculiar to the horse, but maj be com- municated to man by inoculation. It seldom attacks a horse aiter maturity, but attacks colts from birth until they are five DISTEMPER, OR STRANGLES. years old. The causes are many and varied. Among them are want ol nutritious properties in the mother's milk; change from pasture to dry teed; irritation from teething; impure air; changes trom one climate to anothtr, etc. Symptoms: — The colt will appear dull and stupid; the eyes will begin to water and sometimes to matter; fever begins to rise; loss of appetite; coat begins to get rough; discharge from the nostrils; abscesses begin to torm under the lower jaw. In irregular strangles abscesses may torm anywhere on the 8 Equine and Bovine body, or in the lungs or intestines, making the case very se- rious. Treatment: — The treatment is very simple. In regular strangles place the animal in an airy, comfortable, loose box stall and bed well. Blanket comfortably and feed on soft food — such as bran-mashes, chopped feed, mashed turnips or car- rots. If there is a dry cough steam the nostrils with scalded bran or oats, but do not smoke the colt. Poultice the throat with fried onions, boiled turnips or linseed meal; and when the abscesses soften lance them to allow the matter to escape. If the abscesses remain hard apply a good stimulating lini- ment or blister to them, and gargle the throat with the fol- lowing: • Chlorate of Potassium, one ounce. Nitrate of Potassium, one ounce. Hypo-Sulphate of Soda, one ounce. Mix. Make into twelve powders and give one powder every six hours. EPIZOOTIC INFLUENZA. This disease is very peculiar and yet not uncommon in this country. In 1871 it traveled trom east to west with such ra- pidity that there is little reason to doubt that it is produced through atmospheric influences. It is much more dangerous EPIZOOTIC INFLUENZA. in some localities than in others, according to the hygienic measures employed. In localities that are low and malarious with poor stabling: the disease is much more fatal than where the elevation is greater and the air dryer. But no location is MarDiciNE AND Surgery. 9 exempt from the disease. In the same stable a number of horse may be attacked, and very severely, while others remain perfectly healthy. Every horse in a given stable may be aiiected, while their neighbors in a stable across the street escape entirely. It is my opinion that horses poorly cared for and ill-ted are, not only first attacked, but the first to succumb. Symptoms: — The disease comes on very suddenly with weakness and stupor; eyes swelled and watery. The mem- branes of the nostrils may be of a bright pink color, but are more frequently of a Jdull leaden hue. There is dry cough; staring coat; ears and legs alternately hot and cold; patient is feverish; pulse accelerated — generally weak but sometimes hard; sometimes a watery discharge from the nostrils, after- wards assuming a yellowish or greenish color; appetite lost; when made to move will go with a swinging gait, — frequently crackling of the joints will be heard, when the disease assumes a somewhat rheumatic nature, the legs swollen, hot and very painful when touched. In other cases the lungs or abdominal viscera may be seriously involved. If the horse is tucked up along the abdomen, with hard pellets of faeces covered witii FIRST STAGE OF EPIZOOTIC INFLUENZA. mucus, the bowels are attacked and your case is somewhat dangerous. If the patient is tucked up in the flanks, with a ridge extending from the flanks to the breast bone, hurried breathing and short painful cough, the disease has attacked some part ot the thoracic cavity, — either the lungs or the pleura, probably both — and is extremely dangerous. Treatment; — When first noticed place in a comfortable, loose box-stall, well aired but without draughts. Blanket well and bandage the legs. Relieve costiveness with a pint of 10 Equine and Bovine linseed or castor oil and injections of warm water. If the fever is high give, Quinine Sulph., three drams. Nitrate Potass., one ounce. Bi-Carbonate Soda, one and one-half ounces. Mix. Make into six powders, of which give one every five or six hours. It the horse is very weak give, Liq. Ammon. Acet, eight ounces. Spts. Nit. ^th., lour ounces. Tinct. Nux Vomica, two ounces. Mix. Give two ounces every three or tour hours in a little water as a drench. Bathe the throat with a good strong liniment. Feed on soft nutritious diet and give plenty ot pure fresh water. If the joints swell bathe with Scotch Oil liniment and bandage. If there are any lung complications use mustard freely on the sides and read treatise on lung diseases. If the bowels are aifected give linseed jelly, slippery-elm, etc. SPASMODIC COLIC, CRAMPS. Several diseases of horses, — such as affections of the kid- FIRST STAGE OF SPASMODIC COLIC. Medicine and Surgery. 11 nejs, liver, spleen, etc., cause abdominal pain and are errone- ously classed under the head of colic. I shall not treat of them here, but confine myself to spasmodic colic proper, which is a disease of the intestinal canal usually confined to the stomach and small intestines, — an involuntary contraction of the muscular fibers, separate and distinct from inflammation, at the beginning causing intense pain in the abdominal region. There are many and various causes, — sucli as change of feed from oats to corn; too high leeding; sudden changes ot temperature, from hot to cold; standing in the rain; drinking ice-cold water; innutritions food; in fact, anything that will cause indigestion or irritation of the intestinal canal. Symptoms: — The horse will generally appear uneasy, com- mence pawing and attempt to lie down, sometimes f alHng upon his knees, then raising himself up again. As the pain in- creases he will paw violently, suddenly drop down, roll around tor a time, get up and stand apparently easy for a few minutes, possibly attempt to eat a few mouth-f uls. Then he is suddenly SECOND STAGE OP SPASMODIC COLIC. seized again paws violently, drops down again and rolls around, — possibly rolls upon his breast and remains there for a time. Then commences tumbling and rolling again; gets up and shakes himself, and possibly the cramps are over. If not, and the pain continues to increase in intensity and the animal is not relieved, inflammation of the bowels "(which is very dan- 12 Equine and Bovine. gerous) may result; or tlie horse may die from pain and exhaustion. Treatment :— Place the animal in a diy well bedded stall, 1/ 1/ LA.ST STAGE OF SPASMODIC COLIC. where he is less liable to braise himself. Kub the legs and abdomen and give, Barbadoes Aloes, one ounce. Chloral Hydrate, one dram. Powdered Opium, one dram. Mix. If the pain increases, give, Spts. Kitrous JEther, one and one-halt ounces. Laudanum, one ounce. Oil of Peppermint, thirty drops. Spirits of Turpentine, six drachms. Linseed Oil, one-half pint. Mix. Should the pain continue repeat the latter prescription in fortv minutes, or give Scotch Colic Cure. If you have failed to give the aloes, after the pains have subsided it is good policy to give a good physic, — either a pint of linseed oil or one ounce of Barbadoes aloes and an ounce of ginger combined,. Medicine and Surgery. FLATULENT COLIC. 13 Flatulent colic is a disease separate and distinct from spasmodic colic. In the former there is bloating, or distension with gas, of the bowels; in the latter there is no bloating FIRST STAGE OF FLATULENT COLIC. whatever. Flatulent coHc is generally caused by some indi- gestible food setting up a ferment and creating a greater amount of gas than can be comfortably accommodated by the bowels, thus causing intense pain. Symptoms:— The horse will hang his head and commence looking around at his flanks; soon he will begin pawing, then ADVANCED STAGE OF FLATULENT COLIC. will lie down and roll, frequently looking at the flanks; the 14: Equine and Bovine animal begins bloating and sometimes has eructations ot gas from the stomach; the bowels grow more distended; the pains are continuous and grow more severe; the breathing is shorter and the animal groans or grunts while lying down and often while standing; the legs and ears become cold; cold sweats break out over the body. The disease is usually of short duration and, it not speedily relieved, ends in death. Treatment: —When first noticed give, Linseed Oil, one pint. Spts. Turpentine, two ounces. Mix. II that fails to neutralize the gas give, Liq. Ammonia Acet., three ounces. Chloral Hydrate, one dram. Bi-Carbonate Soda, two drachms. Tinct. Aconite, twenty drops. Water, one-halt pint. Kepeat every thirty minutes: or give Scotch Colic Cure. Give injections of hot water and castile soap every FLATULENT COLIC — LAST STAGE. twenty minutes. If the bloating continues tap with a trocar and canala, on the right side, between the hip and ribs, where it Medicine and Surgery. 15 is most resonant on percussion. Alter recovery give a pint of linseed oil or castor oil. GLANDERS AND FARCY. Glanders is a specific febrile disease peculiar to the horse, mule and ass; and, by inoculation, it can be communicated to man. Its causes are keeping horses in damp filthy stables; impure air; improper feeding; impaired nutrition; sequelae of ''grease heels;" sequelae of epizootic influenza; also contagion, which is by far the most connnon. Symptoms: — Dullness; decreased appetite; eyes watering; fever, rising from 102° to 107° F. ; coat staring; at first watery discharge from the nostrils; discharge afterwards turns to a yellowish and later to a yellowish-green, and is very tenacious; in the nostrils reddish ulcerations appear, later becoming GLANDEBS. purplish; all over the body the lymphatic glands become enlarged, frequently breaking and discharging matter; the sub-maxillary glands enlarge and harden, later on becoming adherent to the jaw; breath foetid; by auscultation crepitation of the lungs will be discovered; the discharge from the nos- trils becomes very profuse and more greenish in color; fever now stands from 105° to 107° F. ; quite frequently the limbs will swell, — more particularly about the joints. Treatment: — The best treatment is destruction of the ani- mal as soon as thoroughly satisfied he has glanders. Separate all animals which have come in contact with him. If treat- ment be attempted place the animal where he can have plenty of fresh air and try the Sulphites, — as Sulphite of Sodium, Benzoate of Sodium, Arsenate of Strychnia, Carbolic Acid; 16 Equine and Bovine also vegetable and mineral tonics, — as Sulphate of Iron, Sulphate of Copper, Gentian, Ginger, Nux Vomica, etc. ANEMIA. This is a term used to denote a deficiency of red corpuscles in the blood. The disease is caused by excessive bleeding, deteriorated lood; keeping in ill- ventilated filthy stables, without much light; effects of fevers; severe or protracted diarrhoea; leucorrhoea; it sometimes results from epizootic influenza. Symptoms: — Pallor of the mucous membranes; is tucked up in the flanks; cardiac palpitation; disinclination to move; staggering gait; paleness of eyes and eye-lids; coat more or less rough; later on, if ahorse, a swelling of tlie sheath, — if a mare swellings of a dropsical nature under the breast, slight at first, but gradually extending both backward and forward, in the horse usually extending from the sheath forward; the limbs beg:in swelling, sometimes reaching an enormous size; on scarifying the swelling there will be an oozing out of serum, barely colored with blood, which may be continued for days, — you will, also, find the flesh of a bluish color; appetite sometimes fair, usually for hay but not for grain; bowels generally constipated, but sometimes a diarrhoea will set in which, if not checked, will commonly prove fatal; rumbling of the bowels is invariably a constant symptom. Treatment: — If possible remove the cause as soon as can be; give plenty of light and fresh air. If necessary regulate the bowtls with a pint of castor oil. Give strengthening and easily digested food, — such as ground oats, beans, boiled flax seed, etc. Administer such remedies as will tend to build up the system, as. Sulphate of Iron, two ounces. .Gentian, one ounce. Nux Vomica, one ounce. Arsenic, thirty grains. Mix. Make flfteen powders: give one powder every flve or six hours; or use any of the mineral and vegetable tonics, as, Cascarilla, Quassia, Gentian, Sulphate of Copper, etc. Regu- late the kidneys with dram doses of Nitrate of Potassium. Bed the animal well. When the sheath is much swollen scarify lightly. Mp:dicine and Surgery, 17 AZOTURTA. By some this disease has been described as a disease of the kidneys, by others as a disease of the spine and by others as a disease of the liver. But I have invariably found the whole system more or less affected, from an abnormal amount of nitrogen in tlie blood, wliich is caused by high feeding and want of exercise. As the animal is put to work there is a greater amount of waste material cast upon the excretorv organs* than they can well dispose of ; hence an excess of nitrogen is formed in the blood and is carried through the system, invariably settling in the myolema or coveri^igs of the deep muscles of the haunch, causing partial and sometimes complete paralysis of the hind extremities. Symptoms: — Invariably the horse leaves the stable in the best of health, and, as the driver says, "the horse was never feeling better." But it is probably not driven over halt a mile, possibly five or six miles, when he is noticed to hang back, to be covered with profuse perspiration, and to begin to be stiff in his hind legs. Other symptoms are, looking back at the flanks; anxious expression ot countenance; breathing short; nostrils distended and red; staring eyes; drooping of the hind legs and knuckling over at the fetlocks, as though there were no strength iu them; after staggering around for awhile the animal falls and is unable to get up, — although they sometimes keep upon their feet in a mild attack and, if so, are most likely to recover in a few days; if urine is passed it will be very dark, sometimes looks bloody, smells very strong and be very ropy. Treatment: — If the horse remains very uneasy give ounce doses of laudanum every thirty minutes until relieved; then remove to a comfortable place and bed well. Clean out the bowels well by giving, Barbadoes Aloes, eight to ten drams. Ginger, two drams. Mix. Give in one pint of water as a drench. While the animal is perspiring blanket well and keep sweating. Apply a fresh sheep-skin over the loins and cover well, or apply cloths wrung out of hot water over the loins, and be careful the animal does not take cold. If the kidneys do not act freely give one ounce 18 Equine and Bovine Tinct. Buchu Compound every six or seven hours in a little syrup as a drench. And in a few days give, Tincture Gentian, two ounces. Tincture Nux Vomica, two ounces. Tincture Ginger, four ounces. Alcohol, eight ounces. Mix. Give two ounces every four or five hours. Bathe the back and loins with a good strong liniment once or twice a day, also rub from the stifle to the point of the hip. Turn the horse over from one side to the other every three or four hours, and occasionally sponge him off with dilute alcohol. If shod remove the shoes and keep lying upon the breast as much as possible. I belie ^^e it bad policy in such cases to swing the horse, unless the slings can be got under them before they go (3o^n^ — then it is advisable; but after they are down for a few hours do not attempt to swing. If the patient lies upon his breast well and rests easy you may look for recovery in a few days; if he lies straight out the inevitable result is death in a few days. Should the animal not urinate properly, pass the catheter and draw off the urine. If in twenty-four hours the bowels do not respond to the aloes, give a quart of raw linseed oil; also give injections of castile soap and hot water. EPISTAXIS, OK BLEEDING i'KOM THE NOSTKILS. This disease seldom occurs. It is usually caused by hard running, sneezing, coughing, or by external injuries. Symptoms: — If the blood is merely dropping from the nos- trils some small blood-vessel is ruptured. If the blood flows in a stream, and is of a bright scarlet color, it comes from the lungs, If it comes away in dark colored clots, it is, in all probability, coming from the stomach. Treatment: — Elevate the head and apply cold water to it, and inject weak solutions of alum water. Sulphate of Zinc, or largely diluted Sulphuric Acid. Plug the nostrils with a sponge, — but be sure and have a string tied to it to draw it out. You can only plug one nostril at a time. NASAL CATAKRH, OR COLD IN THE HEAD. . This quite frequently arises from standing in a draught, from ihhalation of irritating gases, or from decayed teeth. Medicine and Sukgery. 19 Symptoms: — Discharge, watery at first, from the nostrils, also trom the eyes; sneezing; later on a discharge of matter from the nostrils, — sometimes very foetid, especially when from a diseased tooth; sometimes ulcers will appear on the septum of the nose, when the discharge is of a muco-purulent character. Treatment: — Steaming the nostrils with hot water and a little carbolic acid is very beneficial. Twice a day use a spray of Listerine one-half ounce to water two ounces. If from a diseased tooth the tooth should be extracted and, if there is matter in the frontal sinuses, they should be trephined and washed out with, Listerine, four ounces. Sulphate of Zinc, one-half drachm. Water, four ounces. Mix. Use morning and evening. Feed on good feed with a few tonic powders. CHKONIC KOAEING. This is so-called from the roaring, rasping, unnatural sound when the horse is put to work and is caused by atrophy or wasting of the muscles on the left side of the larynx; by dis- temper; by epizootic influenza; by polypus in the nostrils; also by spasmodic constriction of the bronchial tubes from tonic contraction, mostly reflex of the involuntary muscular fibers; by fracture ot the bones of the nose,— when the fracture is depressed; by an extra amount ot fat; by dropsical swellings, etc. Treatment: — First, if possible, remove the cause. If that cannot be done treatment is useless. If caused by atrophy of the muscles of the larynx apply every fitth day, for three or four applications, a blister of Vaseline, one ounce. Bin-Iodide Mercury, one dram. Powdered Cantharides, one dram. Mix. If caused by polypus, have it removed. If from fat, reduce in flesh. In the majority of cases the roaring is made during the inspiration. The horse seemingly inhales more air than the lungs can dispose of; consequently he roars and 20 Equine and Bovine chokes down wLen put to work. ] >j using a clasp over the nostrils, it holds them so he can onl}^ take in a certain amount of air at each inspiration; when put to work, the roaring will be stopped and the horse will do a reasonable amount of work. The clasp may be taken ofi after he has been working an hour, and, in the majority of cases, the animal will breathe freely. In order to keep horses from roaring badly, work them mod- erately every day. BRONCHITIS. This is an inflammation of the mucous membrane which lines the bronchial tubes; it is invariably caused by standing in draughts while overheated. Symptoms: — Systemic depression; dullness; loss of appetite; redness and dryness of the mucous membrane of the nostrils, followed by fever and a hacking, barking cough ; rattling in the anterior part of the chest; in a few days a light colored dis- charge from the nostrils; the cough now becomes deeper and looser; instead of being, as iit first, rapid the pulse becomes softer and niore natural. Treatment: — Place the animal in a comfortable and airy stall and blanket well. Apply mustard to the sides and breast and give, Quinine, thirty grains. Dover's Powders, one dram. Liq. Ammonia Acet., three ounces. Mix. Give every four or five hours; and if the cough is very tight give every three or four hours. Syrup of Ipecac, four drachms. Syrup of Squills, six drachms. Tinct. OpiiCamph., six drachms. Mix. Continue until the cough softens. SORE THROAT, OR LARYNGO-PHARINGITIS. This disease affects the larynx and pharynx, situated at the upper part of the wind pipe, and consists of an inflammation of the soft tissues of both. Symptoms: — This disease is sometimes ushered in by a chill, immediately followed by fever; and if the attack is very severe, Medicine and Surgery. 21 the nose will be elevated, to straighten the air passages. Swellings, sometimes very large externally, but more frequentl}" will be noticed behind the jaws on the neck. Sometimes they are so extensive that the animal can scarcely breathe or can only do so with the greatest difficulty; there will be a wheezing sound at each inspiration. During this period the heart be- comes excited and its pulsations rapid. The mucous membranes in the nostrils will be of a bluish color, owing to the lack of sufficient fresh air in the lungs to oxidize the blood. If the patient is in a box-stall it will wander around considerably and endeavor to keep its nose in the direction where there is most fresh air. If the animal attempts to eat, the food will be chewed and dropped out of the mouth; and, on attempting to drink, the water will be ejected through the nostrils. In some •cases the cough is very loud, but in many, — especially when the internal swelling is very great, the cough will be very slight. Frequently there is a discharge from the nostrils and an abundant How of ropy saliva from the mouth. Treatment: — Blanket well and place the patient in a ■comfortable and airy box-stall, devoid of draughts. Bandage the legs and, if possible, give as a physic: Aloes, se^^en drachms. Ginger, one dram. Mix. Give at one dose. Then bathe the throat well with hot water and wrap it up with rugs or sheep-skins to keep it warm. Steam the nostrils with scalded bran or oats and give, Solid Ext. Belladonna, one ounce. Chlorate of Potassium, one ounce. Pulv, Glycyrrhiza, one ounce. Gum Camphor, one-half ounce. Honey, or Simple Syrup, one-half pound. Mix. Give a table-spoonful three times a day. If the weather is in any way cold or disagreeable, be very careful about bathing the throat with hot water, as the patient may take cold. So, immediately after bathing, apply Scotch Oil and the danger from cold will be greatly lessened. It also acts as a good counter-irritant, reduces the swelling, removes the effu- sions by promr)ting absorption, and leaves the patient less liable to be "thick winded," or "a roarer." The diet should 22 Equine and Bovine be of soft feed, as bran mash, or chopped feed mixed with a little linseed meal. Sometimes it is advisable to gargle the mouth with some cooling lotion ; in such cases use, Powdered Chlorate of Potassium, one ounce. Powdered Nitrate of Potassium, one ounce. Bi-Carbonate of Soda, one ounce. Mix. Make into twelve powders. Three times a day mix one powder with half a pint of water and gargle the mouth. If the swelling "points," open with a lancet and allow the pus to escape. Dress the cavity three times a day with, Permanganate of Potassium, one dram. Water, eight ounces. Mix. PITEUMONIA, OR INFLAMMATION OF THE LUNGS. This consists of an inflammation of the lung substance caused by catching cold ; inhaling irritating substances; injuries; drenching through the nostrils, etc. Symptoms: — Tlie horse is generally taken with a chill; hangs his head; there is redness of the eyes and of the membranes of the nostrils; dryness of the mouth; a cough^ COMMENCEMENT OF INFLAMMATION OF THE LUNGS. quite deep at first, which gradually shortens for a few days; pulse, at first generally full, gradually growing faster and weaker; rapid breathing; on the third day fever ranges from 103° to 106° and continues until about the sixth or seventh day, when it gradually declines; on the third or fourth it is likely there will be a discharge of mucus from the nostrils; about the seventh day, when the fever subsides, the horse will either get well or there will be great oppression in breathing; Medicine and Surgery. 23 increased prostration; deeper cough; more copious expectora- tion, emitting a foetid, purulent odor; and death will result from the sixth to the twentieth day. Treatment: — Place the animal in a comfortable, airy, loose box-stall, devoid of draughts. Blanket and bandage the legs with flannel. Some practitioners will scoff at the idea of bleeding, nevertheless a plethoric, robust horse, in many instances, will be greatly benefited in the first three or foar days by being bled, while an older and debilitated patient would succumb. Apply mustard to the sides and give the following: Liq. Ammonia Acet., twelve ounces. Spts. Aeth. Nit., four ounces. Fluid Ext. Aconite, two drachms. Mix. (live two ounces every three hours in a little water as a drench. Also give every four or five hours, Quinine Sulph., twenty grains. Nitrate of Potassium, forty grains. Mix. Or, Powdered Ext. Belladonna, one scruple. Gum Camphor, two scruples. Nitrate of Potassium, one dram. Mix. Give all the water the horse will drink, — just as it comes from the well, and feed on soft diet. It there is great pros- tration give tonic stimulants, as. Alcohol, eight ounces. Tinct. Ginger, three ounces. Tinct. Nux Vomica, two ounces. Tinct. Gentian, three ounces. Mix. Give two ounces as occasion demands. PLEURISY. This is an inflammation of the lining membrane of tlie thoracic cavity. Generally after a chill or cold stage sharp pains begin in the sides; the animal frequently will look at his sides and lie -down very carefully, then rise again; the skin is hot; breathing short; also a short cough; 710 discharge from 24 Equine and Bovine the nose; pnlse hard and rapid; abdomen tucked up, and a ridge extending from the hips to the breast-bone; on punching between the ribs, when the seat of inflammation is reached^ the animal will evince pain by grunting; if the animal lies PLEURISY. down it will invariably lie on tne affected side, but they more frequently stand up. The second day effusion of serum takes place; then the pulse will become slower and fuller, breathing will be easier and the animal seemingly is well again. And, if the effusion is not very great, it will soon be absorbed and the animal is well. But, if the effusion is great, the breathing becomes hurried and short; the pulse grows fast and weak; the ridge from the hip to the breast is more prominent; appe- tite almost completely gone, cold sweats break out and imminent danger is at liand. Treatment: — In the early stage bleeding is beneficial, but later on detrimental. If the pain is very severe give, Fluid Ext. Aconite, fifteen drops. Acetate of Morphia, ten grains. Mix. Eepeat in two hours. If the pains subside give the following, —one ounce every three or four hours: . Fluid Ext. Aconite, two drachms. Fluid Ext. Belladona, four ounces. Spts. Aeth. Nit., four ounces. Mix. Apply a large linseed meal poultice to the affected side, and, if recovery is beginning, give as a physic, Barbadoes Aloes, seven drams. Ginger, one dram. Mix. Medicine and Surgery. 25 But if the effusion of serum within the thoracic cavity is very great and the breathing hurried the chest should be tapped. Although the operation is simple and easily per- lormed, it does not always result satisfactorily, probably because delayed too long. The proper place to operate is between the eighth and ninth ribs, as close as possible to the ninth rib. It should be done with a trocar and canula, two- thirds the way down toward the bottom of the chest. After tapping give the following: L/dide of Potassium, one ounce. Spts. Frumenti, one pint. Mix. Give a wine-glassful every six hours; also give daily one ounce of Tinct. Perchloride of Iron. Appl}^ a good mustard plaster to the sides or a good cantharides liniment. HEAVES. This disease very closely resembles asthma in man, but is more continuous in its symptoms. One of the principal causes is over-feeding on clover hay, but over-feeding with any bulky food, causing overloading and distension of the stomach, will produce heaves. Diseases of the lungs are also said to be a cause. I believe that large horses with small chests are more susceptible to this disease than those with large chests. Therefore, from mares that breed such colts with small chests, developing heaves at the peri
