“ With a 25-percent cutting loss, which is not unusual, a 600-pound carcass would yield approximately 450 pounds of usable meat cuts. A good rule of thumb for carcass beef is 25 percent waste, 25 percent ground beef and stew meat, 25 percent steaks, and 25 percent roasts. Thus a 1,000-pound steer will, on the average, yield about 450 pounds of usable meat cuts. This figure can easily be as high as 550 pounds for an animal with very little waste fat to as low as 300 pounds for an animal with excessive waste fat. ”

“ Several factors should be considered before slaughtering a beef animal for home consumption. The most important considerations are health, kind of animal (calf, steer, or heifer or cow) , expected meat yield, and care of the animal prior to slaughter.
Health
One should take care that an unhealthy animal is not selected for slaughter. At the time of selection, look for signs of sickness such as fever, increased breathing rate, and diarrhea. Animals suspected of being unhealthy should be treated by a veterinarian until the animal is returned to a healthy state. ”

“ All parts of the pork carcass can be cured. The hams, shoulders, and bellies are usually cured. Although the loin can be cured, it is generally used fresh as chops or roasts.
The ingredients used in curing are salt, sugar, and sodium nitrate or nitrite. Salt is the preserving agent; nitrates (dry cure only) and nitrites are added for color and flavor development, but are also preserving agents. Sugar is used to counteract the harshness of salt. Commercial cures are available with some added spices and flavorings to give a characteristic flavor, aroma, or appearance. ”

“ The kind of animal one selects for slaughter will depend on its ultimate use. For meat similar to U.S. Choice in palatability it is necessary to select a 1,000 to 1,200-pound steer or a 900 to 1,000-pound heifer that has been on full feed for at least 150 days. The time on feed influences palatability because of the fat content in the lean. Unfortunately, as most animals deposit fat in the muscle, they also deposit fat around the muscle. Much of the outside fat is usually trimmed off during cutting. ”

“ Once the animal is bled, the hair can be removed by scalding the animal in hot water and scraping; or the skin and hair can be removed by skinning. Traditionally, hogs have been scalded and scraped, and the skin is left intact. Both procedures will be discussed because many people now find the skinning method to be easier, to require less equipment, and to result in an equally acceptable final product. ”

“ Chops or roasts from the leg, loin, back, or shoulder are suited to dry heat cookery methods such as broiling or roasting. Other cuts from the lamb carcass such as stew meat, neck slices, lamb riblets, and shank are best suited to moist cookery methods such as braising. Lamb should be served hot and not allowed to cool before serving. ”

“ The skinning procedure used for pork carcass is similar to that used for beef carcasses. Skinning requires less equipment and can be done faster than scalding and scraping. We have commonly believed that the skin was needed on hams and bacon to assure proper curing; however, this belief is not necessarily correct. A poor skinning job can lower the quality of the belly for bacon. ”

“ The animal must be killed as quickly and humanely as possible. In a slaughter house the cattle are driven into a knocking pen where they are stunned with a compression gun. On the farm a mechanical stunner is usually not available; therefore, stunning is best accomplished with a well-directed long or long rifle bullet from a .22-caliber rifle. As with the use of any firearms, normal precautions should be taken when stunning the animal.
The purpose of stunning is to render the animal unconscious so that its throat can be cut. ”

“ However, congestion or inflammation of the lungs, intestines, kidneys, inner surface of chest, or abdominal cavity and numerous yellowish or pearl-like growths scattered throughout the organs should be viewed seriously. Carcasses and viscera having such abnormalities should be examined by a graduate veterinarian and his opinion obtained as to the wholesomeness of the meat. You should check with a cooperating veterinarian before you slaughter the animal to be certain he will be available if you should seek his advice. ”

“ If the animal’s age is less than 17 to 18 months, the properly prepared cooked meat should be relatively tender. Yearlings just off the cow with perhaps a short period on grass, weighing 400 to 600 pounds, will produce meat low in fat. This meat will be less flavorful than meat from grain-fed animals but should be acceptably tender. Many persons who slaughter on the farm expect the meat from an 800-pound forage-fed steer to taste like U.S. Choice or Prime.
Meat Yield
Well-fed steers from most beef breeds yield a dressed carcass weighing approximately 60 percent of the animal’s live weight. ”

“ The type of smokehouse and the outside temperatures are important factors in the length of time required to smoke meat. Federal meat inspection regulations state that whenever the fresh appearance of a product containing pork muscle tissue has been altered to resemble a product that may mistakenly be eaten without cooking or with less than thorough cooking, it must have been treated in an acceptable manner to destroy possible live trichinae by heating to an internal temperature of 137° or otherwise treating (see page 62) . ”

“ The mirror-smooth steel for razor-sharp edges is the one best suited for slaughter and meat cutting. The steel should be held firmly in the left hand in a position almost diagonal to the body but with a slightly upward tilt. This permits the free movement of the knife across the steel without drawing it too close to the supporting hand. Place the heel of the blade against the near side of the tip at a 20° to 25° angle and bring the blade down along the steel toward the left hand with a quick, swinging motion of the right wrist and forearm. ”

“ If done properly, pork can be satisfactorily preserved by canning. Meat is a low acid, high protein food that allows for good bacterial growth. The use of a pressure canner is vital to ensure that the sterilization temperature (240° F) is reached and maintained for the proper length of time. A water bath or a steamer is not recommended since neither one attains a sufficiently high temperature to produce effective sterilization. Meat may be canned soon after chilling since aging has little effect on the flavor and tenderness of canned meats. ”

“ Figure 15.—Splitting hide down midline.
If a cow is being slaughtered, do not split through the center of the udder. Cut the hide around each side of the udder and remove by lifting it and cutting along the body wall. Removal of a large udder will make siding easier and prevent any fluids contained in the udder from spilling onto the meat.
Begin siding by splitting the hide on the inside of the round (fig. 16) . Starting with the cut made in removing the hindleg, cut downward to the midline split, just behind the scrotum or udder. Cut “inside out” and do not cut through the fat into the meat. ”

“ The meat-type hog should have full, plump, meaty hams and straight, smooth sides. Fat should be firm, evenly distributed, and not more than 1.6 to 1.7 inches average thickness over the back. The average meat-type hog produces as much pork as a family of two consumes in 10 to 12 months. Heavier, fatter hogs produce less lean and more excess fat.
A meat-type hog, when cut and trimmed according to the methods described later, will yield approximately 65 to 70 percent of its carcass weight in ham, picnic shoulder, loin, bacon, and Boston butt. ”

“ For example, a 1,000-pound live steer yields a 600-pound carcass. Yields will vary according to the feeding ration and the length of time on feed. Cutting losses from the carcass, such as bone or fat trim, vary from 20 to 30 percent or more. ”

“ Since an inexperienced person will take 2 to 3 hours to complete the slaughter operation, care should be taken to avoid long exposure of the carcass to high temperatures. During cold weather of less than 30° F, the animal can be slaughtered at any time, because spoilage bacteria do not grow rapidly at cold temperatures. During periods of extremely cold weather, avoid letting the carcass freeze immediately after slaughter because the meat will be less tender than if it is permitted to chill without freezing. ”

“ Grinding (fig. 2) is necessary because new knives are not usually sold in a form sharp enough for immediate use. The stone should be water, or oil-cooled to avoid overheating the knife. The blade should not be ground back more than 1⁄4 inch from the edge to form the proper bevel. The bevel should be the same on both sides of a skinning knife so that it may be used with either hand in removing the hide from a beef carcass. It is best to grind the knife by holding the knife edge against the stone at a right angle to prevent scarring the blade any farther back than the actual bevel. ”

“ Figure 45.—Intestines and stomach.
Pull the loosened large intestine down past the kidneys (fig. 46) . Sever the attachments to the liver and remove it by pulling outward and cutting the connective tissue (fig. 47) . Remove the gall bladder from the liver by cutting beneath it and pulling (fig. 48) . Be careful not to allow its contents to spill onto the liver. ”

“ Figure 87.—Foreshank crosscuts and brisket.
Turning now to the blade section of the forequarter, remove the sixth rib by cutting between the fifth and sixth ribs and sawing through the backbone (fig. 88) . This roast, or roasts from the fifth and fourth rib sections, can be used as is (fig. 89) or separated into several usable pieces. The outside muscles may be removed by cutting along the fat seam through the middle of the roast (fig. 90) . These muscles are less tender and should be cooked with moist heat like a pot roast or made into stew meat or ground beef. ”

“ Do not allow the carcass to freeze because freezing within 1 day after death may toughen the meat. If the carcass cannot be chilled to below 40° F on the farm, it should be transported to a local locker plant or market for chilling. The need for prompt and thorough chilling of warm carcasses cannot be over-emphasized for the inhibition of bacterial growth. The carcass can be cut into retail cuts after it has been chilled for 24 to 48 hours. ”

“ It is very important for safety that the fingers of the left hand push downward only to maintain an even pressure on the knife blade over the stone. If the left hand pushes laterally with the sharpening stroke, and the knife catches on an irregularity, then the fingers will slip off the edge and can be cut severely by the freed knife blade. With a sweeping motion toward the right of the stone, draw the knife completely across the stone, against the cutting edge of the blade. ”

“ The femoral artery of the ham is located above the big flat bone which is cut when the ham is separated from the carcass. The artery is about halfway between the cut surface of the bone and the point of the aitch bone. With small forceps, you can clamp the end of the artery and push tissue and loose fat away so the pumping needle can be inserted. Stitch pumping is not as effective as artery pumping but is more so than either dry or pickle cure. ”

“ This procedure ensures that the paunch and intestines are not cut. Continue cutting down the midline to the cut made when opening the brisket (figs. 44 and 45) . Loosen the large intestines as shown in figure 46, making sure that the pelvic and kidney fat, as well as the kidneys, are left attached to the carcass. Pull down on the paunch and intestines and allow them to fall into a container or onto the ground. As the paunch falls, a small cut with a knife will free the liver from the connections to the intestines and paunch (fig. 47) . ”

“ Expected yields of major and minor cuts from a U.S. No. 2 hog are presented in table 1.
The slaughter of boars is not recommended. Meat from boars has a strong odor during cooking, and an off-flavor. This “sex” odor and flavor is often identified as being “soapy,” and the odor increases as boars approach sexual maturity. If old boars are to be slaughtered, they should be castrated and allowed to heal prior to being slaughtered. ”

“ Frozen pork, particularly cured or seasoned pork, will not retain its quality as long as beef or lamb. Pork should be frozen as soon after cutting as possible before any spoilage or rancidity can occur. Usually the hams, bacon, and shoulders are cured and do not require freezing. ”

“ Headcheese is easy to make. Split the head, remove the eyes, clean the ears and nostrils, cover the cleaned pieces in water with the tongue, heart, and some lean trimmings and cook until the meat is well done and separates easily from the bones. Grind the meat and cover with broth. Add seasoning (salt, pepper, and others if desired) , cook for 15 to 20 minutes and pour into pans. Headcheese can be eaten cold or fried the same as scrapple or panhas. ”

“ Tender cuts of meat are best cooked with dry heat such as broiling, roasting, and panbroiling. Less tender cuts of meat are tenderized by cooking with moist heat. Connective tissue is softened and tenderized by cooking slowly in moisture. ”

“ Fresh pork sausage is generally made by grinding and seasoning lean pork trimmings from bellies, hams, and shoulders. Fresh sausage should contain about 20 to 30 percent fat. If more fat is included, the sausage may be too greasy and shrink a lot in cooking. If entire shoulders or hams are used, it may be necessary to add some fat. ”

“ This type of smokehouse is large enough for the cuts from one hog. An old refrigerator or a simple frame house can be used rather than a barrel. The fire can also be built in a ventilated barrel which is connected to the smokehouse by a stove pipe.
Figure 90.—Barrel for smoking.
Permanent structures suitable for smoking meat should be constructed if large quantities of meat are to be smoked. Tight construction and well-fitted ventilators provide effective regulation of the air flow past the meat. An outside firebox makes temperature control easy and reduces fire hazard. ”

“ Disposal of viscera and hair is often a problem. Arrange to have a local processor or rendering plant pick up these wastes. If this is not possible, bury them so that dogs and other animals cannot dig them up. Hair can be burned.
Slaughter Equipment
Elaborate and expensive equipment is not necessary but certain items are essential (fig. 1) . The amount of equipment will depend on the slaughter procedure used. If the carcass is to be scalded rather than skinned, additional equipment will be needed (items 16 to 23) . ”
