CATTLE AND THEIR DISEASES TEXT

of detecting the imposition, without a chemical analysis, till it becomes too late, and the crop is lost. It is, therefore, safest to rely mainly upon the home manufacture of manure. The extra expense of soiling cattle, saving and applying the liquid manure, and thus bringing the land to a higher state of cultivation, when it will be capable of keeping more stock and furnishing more manure, would offer a surer road to success than a constant outlay for concentrated fertilizers. THE BARN. The farm barn, next to the farm house, is the most important structure of the farm itself, in the Northern and Middle States; and even at the South and Southwest, where barns are less used, they are of more importance in the economy of farm management than is generally understood. Indeed, to the eyes of a person of taste, a farm or plantation appears incomplete, without good barn accommodations, as much as without good household appointments--and without them, no agricultural establishment can be complete in all its proper economy. The most _thorough_ barn structures, perhaps, to be seen in the United States, are those of the State of Pennsylvania, built by the German farmers of the lower and central counties. They are large, and expensive in their construction; and, in a strictly economical point of view, are, perhaps, more costly than is required. Yet, there is a substantial durability about them, that is exceedingly satisfactory, and, where the pecuniary ability of the farmer will admit, they may well furnish models for imitation. In the structure of the barn, and in its interior accommodation, much will depend upon the branches of agriculture to which the farm is devoted. A farm cultivated in grain chiefly requires but little room for stabling purposes. Storage for grain in the sheaf, and granaries, will require its room; while a stock farm requires a barn with extensive hay storage, and stables for its cattle, horses, and sheep, in all climates which do not admit of such stocks living through the winter in the field, as is the case in the great grazing districts west of the Alleghanies. Again, there are wide districts of country where a mixed husbandry of grain and stock is pursued, which require barns and outbuildings accommodating both. It may be well here to remark that many designers of barns, sheds, and other outbuildings for the accommodation of farm stock, have indulged in fanciful arrangements for the comfort and convenience of animals, which are so complicated that when constructed, as they sometimes are, the practical, common-sense farmer will not use them; and by reason of the learning which is required for their use, they are altogether unsuitable for the treatment and use which they generally receive from those who have the daily care of the stock for which they are intended, and for the rough usage which they experience from the animals themselves. A very pretty and plausible arrangement of stabling, feeding, and all the other requirements of a barn establishment may be thus got up by an ingenious theorist at the fireside, which will work charmingly as he dilates upon its good qualities, untried; but, which, when subjected to experiment, will be utterly worthless for practical use. There can be no doubt that the simplest plan of construction, consistent with an economical expenditure of the material of food for the consumption of stock, is by far the most preferable. Another item to be considered in this connection, is the comparative value of the stock, the forage fed to them, and the labor expended in feeding and taking care of them. To illustrate: Suppose a farm to lie in the vicinity of a large town or city. Its value is, perhaps, a hundred dollars an acre. The hay cut upon it is worth fifteen dollars a ton, at the barn, and straw and coarse grains in proportion, and hired labor ten or twelve dollars a month. Consequently, the manager of this farm should use all the economy in his power, by the aid of cutting-boxes and other machinery, to make the least amount of forage supply the wants of his stock; and the internal economy of his barn should be arranged accordingly, since labor is his cheapest item, and food his dearest. Therefore, any contrivance by which to work up his forage the closest--by way of machinery, or manual labor--so that it shall serve the purposes of keeping his stock, is true economy; and the making and saving of manures are items of the first importance. His buildings and their arrangements throughout should, for these reasons, be constructed in accordance with his practice. If, on the other hand, lands are cheap and productive, and labor comparatively dear, a different practice will prevail. The farmer will feed his hay from the mow without cutting. The straw will be stacked out, and the cattle turned to it, to pick what they like of it, and make their beds of the remainder; or, if it is housed, he will throw it into racks, and the stock may eat what they choose. To do this requires but one-third, or one-half of the labor which is required by the other mode, and the saving in this makes up, and perhaps more than makes up, for the increased quantity of forage consumed. Again, climate may equally affect the mode of winter-feeding the stock. The winters may be mild. The hay may be stacked in the fields when gathered, or put into small barns built for hay storage alone; and the manure, scattered over the fields by the cattle, as they are fed from either of them, may be knocked to pieces with the dung-beetle, in the spring, or harrowed and bushed over the ground; and with the very small quantity of labor required in all this, such practice will be more economical than any other which can be adopted. In latitudes, however, in which it becomes necessary to stall-feed during several months of the year, barns are indispensable. These should be warm, and at the same time well ventilated. The barn should be arranged in a manner suitable to keeping hay and other fodder dry and sweet, and with reference to the comfort and health of the animals, and the economy of labor and manure. The size and finish will, of course, depend on the wants and means of the farmer or dairyman; but many little conveniences, it should not be forgotten, can be added at comparatively trifling cost. The accompanying cut of a barn is given merely as an illustration of a convenient arrangement for a medium-sized dairy, and not as being adapted to all circumstances or situations. This barn is supposed to stand upon a side-hill or an inclined surface, where it is easy to have a cellar, if desired; and the cattle-room, as shown in the cut, is in the second story, or directly over the cellar, the bottom of which should be somewhat dished, or lower in the middle than around the outer sides, and carefully paved, or laid in cement. [Illustration: BARN FOR THIRTY-FOUR COWS AND THREE YOKE OF OXEN.] On the outside is represented an open shed, _m_, for carts and wagons to remain under cover, thirty feet by fifteen, while _l l l l l l_ are bins for vegetables, to be filled through scuttles from the floor of the story above, and surrounded by solid walls. The area of this whole floor equals one hundred feet by fifty-seven. _k_, is an open space, nearly on a level with the cow-chamber, through the door _p_. _s_, stairs to the third story and to the cellar, _d d d_, passage next to the walls, five feet wide, and nine inches above the dung-pit. _e e e_, dung-pit, two feet wide, and seven inches below the floor where the cattle stand. The manure drops from this pit into the cellar below, five feet from the walls, and quite around the cellar. _c c c_, plank floor for cows, four feet six inches long. _b b b_, stalls for three yoke of oxen, on a platform five feet six inches long, _n n_, calf-pens, which may also be used for cows in calving. _r r_, feeding-troughs for calves. The feeding-boxes are made in the form of trays, with partitions between them. Water comes in by a pipe, to cistern _a_. This cistern is regulated by a cock and ball, and the water flows by dotted lines, _o o o_, to the boxes; each box being connected by lead pipes well secured from frost, so that, if desired, each animal can be watered without leaving the stall, or water can be kept constantly before it. A scuttle, through which sweepings and refuse may be put into the cellar, is seen at _f_. _g_ is a bin receiving cut hay from the third story, or hay-room, _h h h h h h_, bins for grain-feed. _i_ is a tunnel to conduct manure or muck from the hay-floor to the cellar. _j j_, sliding-doors on wheels. The cows all face toward the open area in the centre. This cow-room may be furnished with a thermometer, clock, etc., and should always be well ventilated by sliding windows, which at the same time admit the light. The next cut is a transverse section of the same cow-room; _a_ being a walk behind the cows, five feet wide; _b_, dung-pit; _c_, cattle-stand; _d_, feeding-trough, with a bottom on a level with the platform where the cattle stand; _k_, open area, forty-three feet, by fifty-six. [Illustration: TRANSVERSE SECTION.] The story above the cow-room--as represented in the next cut--is one hundred feet by forty-two; the bays for hay, ten on each side, being ten feet front and fifteen feet deep; and the open space, _p_, for the entrance of wagons, carts, etc., twelve feet wide. _b_, hay-scales. _c_, scale beam. _m m m m m m_, ladders reaching almost to the roof. _l l l_, etc., scuttle-holes for sending vegetables directly to the bins, _l l l_, etc., below. _a a b b_, rooms on the corners for storage. _d_, scuttles; four of which are used for straw, one for cut hay, and one for muck for the cellar. _n_ and the other small squares are eighteen-feet posts. _f_, passage to the tool-house, a room one hundred feet long by eighteen wide. _o_, stairs leading to the scaffold in the roof of the tool-house. _i i_, benches. _g_, floor. _h_, boxes for hoes, shovels, spades, picks, iron bars, old iron, etc. _j j j_, bins for fruit. _k_, scuttles to put apples into wagons, etc., in the shed below. One side of this tool-house may be used for plows and large implements, hay-rigging, harness, etc. Proper ventilation of the cellar and the cow-room avoids the objection that the hay is liable to injury from noxious gases. [Illustration: ROOM OVER THE COW-ROOM.] The excellent manure-cellar beneath this barn extends only under the cow-room. It has a drive-way through doors on each side. No barn-cellar should be kept shut up tight, even in cold weather. The gases are constantly escaping from the manure, unless held by absorbents, which are liable not only to affect the health of the stock, but also to injure the quality of the hay. To prevent this, while securing the important advantages of a manure-cellar, the barn may be furnished with good-sized ventilators on the top, for every twenty-five feet of its length, and with wooden tubes leading from the cellar to the top. There should also be windows on different sides of the cellar to admit the free circulation of air. With these precautions, together with the use of absorbents in the shape of loam and muck, there will be no danger of rotting the timbers of the barn, or of risking the health of the cattle or the quality of the hay. The temperature at which the cow-room should be kept is somewhere from fifty to sixty degrees, Fahrenheit. The practice and the opinions of successful dairymen differ somewhat on this point. Too great heat would affect the health and appetite of the herd; while too low a temperature is equally objectionable, for various reasons. The most economical plan for room in tying cattle in their stalls, is to fasten the rope or chain, whichever is used--the wooden stanchion, or stanchel, as it is called, to open and shut, enclosing the animal by the neck, being objectionable--into a ring, which is secured by a strong staple into a post. This prevents the cattle from interfering with each other, while a partition effectually prevents any contact from the animals on each side of it, in the separate stalls. There is no greater benefit for cattle, after coming into winter-quarters, than a systematic regularity in every thing pertaining to them. Every animal should have its own particular stall in the stable, where it should always be kept. The cattle should be fed and watered at certain fixed hours of the day, as near as may be. If let out of the stables for water, unless the weather is very pleasant--when they may be permitted to lie out for a short time--they should be immediately put back, and not allowed to range about with the outside cattle. They are more quiet and contented in their stables than elsewhere, and waste less food than if permitted to run out; besides being in every way more comfortable, if properly bedded and attended to, as every one will find upon trial. The habit which many farmers have, of turning their cattle out of the stables in the morning, in all weathers--letting them range about in a cold yard, hooking and annoying each other--is of no possible benefit, unless it be to rid them of the trouble of cleaning the stables, which pays more than twice its cost in the saving of manure. The outside cattle, which occupy the yard--if there are any--are all the better that the stabled ones do not interfere with them. They become habituated to their own quarters, as do the others, and all are better for being, respectively, in their proper places. MILKING. The manner of milking exerts a more powerful and lasting influence on the productiveness of the cow than most farmers are aware. That a slow and careless milker soon dries up the best of cows, every practical farmer and dairyman knows; but a careful examination of the beautiful structure of the udder will serve further to explain the proper mode of milking, in order to obtain and keep up the largest yield. The udder of a cow consists of four glands, disconnected from each other, but all contained within one bag or cellular membrane; and these glands are uniform in structure. Each gland consists of three parts: the _glandular_, or secreting part, _tubular_ or conducting part, and the _teats_, or receptacle, or receiving part. The glandular forms by far the largest portion of the udder. It appears to the naked eye composed of a mass of yellowish grains; but under the microscope these grains are found to consist entirely of minute blood-vessels forming a compact plexus, or fold. These vessels secrete the milk from the blood. The milk is abstracted from the blood in the glandular part; the tubes receive and deposit it in the reservoir, or receptacle; and the sphincter at the end of the teat retains it there until it is wanted for use. This must not be understood, however, as asserting that all the milk drawn from the udder at one milking is contained in the receptacle. The milk, as it is secreted, is conveyed to the receptacle, and when that is full, the larger tubes begin to be filled, and next the smaller ones, until the whole become gorged. When this takes place, the secretion of the milk ceases, and absorption of the thinner or more watery part commences. Now, as this absorption takes place more readily in the smaller or more distant tubes, it is invariably found that the milk from these, which comes last into the receptacle, is much thicker and richer than what was first drawn off. This milk has been significantly styled afterings, or strippings; and should this gorged state of the tubes be permitted to continue beyond a certain time, serious mischief will sometimes occur; the milk becomes too thick to flow through the tubes, and soon produces, first irritation, then inflammation, and lastly suppuration, and the function of the gland is materially impaired or altogether destroyed. Hence the great importance of emptying these smaller tubes regularly and thoroughly, not merely to prevent the occurrence of disease, but actually to increase the quantity of milk; for, so long as the smaller tubes are kept free, milk is constantly forming; but whenever, as has already been mentioned, they become gorged, the secretion of milk ceases until they are emptied. The cow herself has no power over the sphincter at the end of her teat, so as to open it, and relieve the overcharged udder; neither has she any power of retaining the milk collected in the reservoirs when the spasm of the sphincter is overcome. Thus is seen the necessity of drawing away the last drop of milk at every milking; and the better milker the cow, the more necessary this is. What has been said demonstrates, also, the impropriety of holding the milk in cows until the udder is distended much beyond its ordinary size, for the sake of showing its capacity for holding milk--a device to which many dealers in cows resort. Thus much of the internal structure of the udder. Its external form requires attention, because it indicates different properties. Its form should be spheroidal, large, giving an idea of capaciousness; the bag should have a soft, fine skin, and the hind part upward toward the tail be loose and elastic. There should be fine, long hairs scattered plentifully over the surface, to keep it warm. The teats should not seem to be contracted, or funnel-shaped, at the inset with the bag. In the former state, teats are very apt to become corded, or spindled; and in the latter, too much milk will constantly be pressing on the lower tubes, or receptacle. They should drop naturally from the lower parts of the bag, being neither too short, small, or dumpy, or long, flabby, and thick, but, perhaps, about three inches in length, and so thick as just to fill the hand. They should hang as if all the quarters of the udder were equal in size, the front quarters projecting a little forward, and the hind ones a little more dependent. Each quarter should contain about equal quantities of milk; though, in the belief of some, the hind quarters contain rather the most. Largely developed milk-veins--as the subcutaneous veins along the under part of the abdomen are commonly called--are regarded as a source of milk. This is a popular error, for the milk-vein has no connection with the udder; yet, although the office of these is to convey the blood from the fore part of the chest and sides to the inguinal vein, yet a large milk-vein certainly indicates a strongly developed vascular system--one favorable to secretions generally, and to that of the milk among the rest. Milking is performed in two ways, stripping and handling. _Stripping_ consists in seizing the teat firmly near the root between the face of the thumb and the side of the fore-finger, the length of the teat passing through the other fingers, and in milking the hand passes down the entire length of the teat, causing the milk to flow out of its point in a forcible stream. The action is renewed by again quickly elevating the hand to the root of the teat. Both hands are employed at the operation, each having hold of a different teat, and being moved alternately. The two nearest teats are commonly first milked, and then the two farthest. _Handling_ is done by grasping the teat at its root with the fore-finger like a hoop, assisted by the thumb, which lies horizontally over the fore-finger, the rest being also seized by the other fingers. Milk is drawn by pressing upon the entire length of the teat in alternate jerks with the entire palm of the hand. Both hands being thus employed, are made to press alternately, but so quickly following each other that the alternate streams of milk sound to the ear like one forcible, continued stream. This continued stream is also produced by stripping. Stripping, then, is performed by pressing and passing certain fingers along the teat; handling, by the whole hand doubled, or fist, pressing the teat steadily at one place. Hence the origin of both names. [Illustration: THE PREFERABLE METHOD.]
