Thesis orf WARREN HH. GOSS, WeETreT ta, for the degreeoof MASTER OF AGRICULTURE. JHESIS SPRING LAMB S&. The young of many of our domestic animals are exten- sively used as an article of food. Veal, Roast Pig, Sping Chickens and Spring Lambs form each in them- selves a special business and the producer wi10 san place them on the market, in prime condition, and the earliest in the season, is usually the most successful. A lamb that would weigh sixty pounds at the age of two months would command the highest market price, while one that only weighed sixty pounds at six months of age, would be of little value, even though it cost more to produce it. The natural season for sheep to produce their young in this clinate is in the spring: heoe to produce marketable lanbs in winter, and early spring conditions mist be established, under which lambs will be produced, am thrive, in winter. The es- sential points in these conditions are the right sort of sheep, suitable feed, and, above all, proper care. The selection of suitable ewes is of first importance as the lamb needs all the vigor that 96429 it can inherit, besides plenty of substantial nour- ishment after it is dropped. Sheep that are large and reach maturity at an early age, are the most desirable, therefore the ewes should be seleoted from the coarse or medium wooled breeds. Ewes having a strain of merino blood, are preferable to full blood coarse wools, as they are less liable to bear twins, and twin lambs are not desirable where rapid growth is important. The Ram should invariably be selected fron the medium or coarse wooled breeds, and should be of good vigor, and fully maturec. The character of the lamb is determined largely by the ram used. Of the various breeds, the Hampshire, Dorsetshires, Shropshire are probably the best, and in the order named; and as the Hampshire has coal black head and legs, they are especially desirable when well marked lanbs are demanded. The market should be stud- ied and a ram selected accordingly. Having selected suitable sheep the next con- sideration is to so mate them that the lambs will be dropped at the proper season. The period of gestation is about twenty weeks; hence 1f we wish December lambs the sheep must be mated in July. 0 do this the lambs mist be weaned early in the preceding spring, and the eves rade to gain in flesh. By so doing the ewes will mate earlier than on the Previous year. By repeat- ing this process, weaning the lambs earlier each year the mating season oan be ohanged to suit, in most cases. Stinting the ewes, and following with high feeding is also an aid in this direotion. Sheep seem to mate best when the weather is cool, and advantage can often be taken of this face to produce the desired result. Turning the rams in for short periods only, either at night or in the morning, is good practice. During summer and autumm the ewes should be cool kept in good pasture, and as the weather approach— es they will gain in flesh if in normal health and vigor, and by the time winter feeding begins, they should be in suitable flesh to go into win- ter quarters. Sheep in pastitre should have a shed under which they can go at will. It serves as a protec- tion from storms, flies, and the scorching rays of the summer sun. If it is made quite dark it is an additional protection from flies, and if the Walls are thick it is cooler. A straw shed, all points considered, is probably the best, when the pasture is not adjacent to the sheep barn. A winter sheep barn, in which to raise iacbs, must be light, well ventilated, and have some means of controling the temperature within cer- tain linits. Sheep enjoy an abundance of fresh air, and they seem to thrive best in a cool place, if the temperatire is Kept oonstant. The walls of the sheep barn should be reason- ably tight, with a goodly number of windows and doors thal can be opened and closed readily. The temperature of the barn should be kept as near that of the open air as possible, as long as it is above twenty degrees Fahrenheit; when it goes below this point, the openings should be closed and the barns kept as near this temperature as possible. The sheep and lambs thrive well when it is mich colder than this if the temperature can be reduced gradually, and then kept oconstant; but in this olimate the low temperatures often come sud- denly amd last but a short time; so it is best not to try to acoustom the sheep to them. Sudden changes effect sheep very quickly. A change of thirty degrees, either wp or down, will @ften throw them “off their feed" for several days; hence the necessity of keeping the sheep barns of as near- ly even termmerature as possible. The internal arrangement of the sheep barn can be varied somewhat, to suit the taste. The things to be considered are convenience in feeding, comfort for the sheep and a system that will cause as little waste of feed as possible. Convenient to each pen there should be a space set apart, into which the ewes cannot go, but to whioh the larbs can have free access. In this space should be arranged feed troughs, for feeding the lambs sev- arately. The sheep barns should be put in good condi- tion, before severe weather sets in in the autum, so that with the first appearance of cold storms, the sheep may be properly housed. When winter sets in the sheep should be sorted, putting sheep of equal size and condition together. They should then be nut into the pens, allowing about twenty to each pen. They should then be ex- amined for ticks and disease, and if either is found, the proper remedy should be apviied. Eaoh pen in the sheep barn should be con rneoted with a yard, into which the sheep should have free access in the daytime, when the weather is not stormy or too cold. When the lambs are a few days old, they with their dams should be allowed the same privilege. The fresh air and exercise seem to be petter for them than close confinement. Sheep,as a rule,are good feeders, and will eat most kinds of food, if fed proverly; but for ewes with lambs there is probably no dry fodder equal to clover hay. They eat it readily and it arpears to keep them in tne best ondition of azy one kind of feed. This with a small grain ration is all that is usually required to keep them in prine con- dition, until the lambs are dropped. More succu- lent food, as ensilage or roots, should then be fed, to increase the flow of milk. Oorn stover may be fed to the ewes as part of their ration with good results, or a ration of bean straw oc- casionally will not injure them; but timothy hay should be avoiced if possible. It produces in- digestion from the effect of which the ewes some- times die. Qmain for the ewes should consist of oats and coorn, fed separately, amd whole, and in sufficient qiantities to keep them in good flesh. An occa- sional feed of 011 meal with the other grain is of value in keeping them in a thriving condition. Sheep do best when fed often. Coarse feed should be given at least three tires dailv, and grain twice. Little and often should be the rule. A supply of pure water should be kept where the sheep can get it at pleasure, and the water troughs should be so arranged that a lanb would not be liable to fall in amd be drowned. Salt should be fed to the sheep often. A good arrangement is to have a chunk of rock salt fastened in each per:, allowing the sheep free ac- cess to it. A mixture oonsisting of three pounds of salt and two of sulylmm, fed each fortnight to every fifty sheep tends to keep them healthy, and drives away tioks also. The season at which the lambs are dropped is always a busy one for the shepherd. The period of gestation in the sheep is somewhat variable, ranging from eighteen weeks to twenty-one or more, As the season approaches for the lambs to be dropped, _ the attendant should be on the alert to oare for the first that make their appearance. If the ewes have been properly selected and cared for and suitable rams used, little trouble will be experienced but the ewes should be watched closely and as the lanbs are dropped, they with their dams should be separated from the flock and pains taken to know that the lamb nurses. If the lamb is strong and the ewe furnishes sufficient milk no further special care is needed; but occa- sionally a lamb is found that appears weak; in this case the ewe should be caught and the lamb held in such a position that it can nurse. It is good prac- tice to examine the ewe's nipples and remove the obstruction which is often found at the end so that the milk may flow freely, else a weak lanb night not be able to start it. If a young lamb becomes chilled, a little milk with a few drops of spirits added and fed to it will usually have the desired effect. Occasionally a ewe is found that cannot deliver the lamb; in this case the attendant can usually deliver it by the use of his hands, and a stout wire loop. It sometimes occurs that a ewe refuses to own her lamb, but if she is confined in @ small close pen with it, for a day or two, she will usually come to own it. In this way a ewe that has lost her lanb may often be made to own another if desirable. When a ewe is found that is not a good milker, or that from ary cause is found to be undesirable, she should be marked, and put to some other use the next season. The raising of lambs on cow's nilk is not usually attended with mxx very satisfactory result- The cow's milk is not so rich as that of the ewe, and it is difficult to prodvce sufficient growth with it; besides it is apt to impair the larbs' digestion and often causes them to die. Lambs are subject to several ailments, anong which are paralysis, from crowding too fast, and indigestion from eating too mich tinothy hay, or similar feed, but treatment is difficult and unsatisfactory. The best way,t0 prevent it as muon as possible by suitable feed and care. When the lambs are a week old, they will be- gin to eat both hay, and grain, and they should be allowed to eat with the ewes at pleasure. In addition they should be fed separately, lightly at first, but with a constantly increasing ration, until they may be allowed all they will eat. Then they should be fed and as often as the ewes are. The feed should consist of corn, oats and oil meal ground coarse or, simply cracked. The lambs eat it readily and thrive well on it. The amount of each oan be varied as oirownstances seem to dictate. When the conditions are favorable the lambs will gain very rapidly, often weighing fifty pounds when they are two months old. The lambs are affected by the same influences as the sheep, and if the changes of temperature are rapid, or the air dam, these rapid gains can- not be attained; but a gain of five pounds a week can reasonably be expected, with good tianarement. There is a period in the growth of lanbs, wnen they begin to change to sheep, when this -. change begins they will gain in stature, but will lose in flesh. This ohange begins usually when the lambs weigh betveen fifty and seventy pounds, and they should be sent to market, before they ar- rive at this stage of their growth. Should any > of the lambs fail to attain suitable size for the spring market, the extra feed and care given then, does not appear to react on them later, for when turned on the pasture, and the srain taken from them, they will contime to grow, and will develop into as good sheep as they would had they not been fed so mich grain. Sheep are timid anirals, and while they are Gocile under careful management, they sare easily excited by rough usage, or by persons to whom they are not accustomed. Care should be exercised, therefore to have them cared for by the same person as much as possible, as the more quiet they are kept the better will be the results. The raising of spring laxnbs requires an apt- itude for the business, on the part of the flock- master; it also requires experience, and good judgment; but when the art is fully acquired, it pecomes a pleasant and profitable occupation.
