Just when i doubt the ideal dish for my dinner. Memories make me realize what my grandpa use to tell me when i was a little naughty boy running half naked...."buddy, only a good big a** loin of this pistola makes the stomachs smile"....yes and that was,
Year later i even learn that the ASS of a cow will tell the true ..Only bread of cow with meaty ass and a street lang of the back will garantee better yeald in pistola cut and meaty large section of it
"ANGUS THE BEEF"
Angus was developed in Scotland and exported to Australia in order to fleece money from the bogan, and Angus beef has followed an identical path. Longtime bogan sustenance vendors McDonald’s and Hungry Jacks, in partnership with industry lobby group Certified Australian Angus Beef Pty Ltd, have managed to convince the bogan that the breed of a cow is the only thing that influences the taste of beef (with the possible exception of putting flame grill markings on it). While non-biased meat experts will tell you that the age, diet, and condition of a cow is much more relevant to how its meat will taste, the hungry bogan has no time for listening to these ivory tower academic intellectual arseholes.
Angus Cattle (Aberdeen Angus)
Are a breed of cattle much used in beef production. They were developed from cattle native to the counties of Aberdeenshire and Angus in Scotland and are known as Aberdeen Angus in most parts of the world.They are naturally polled (do not have horns) and solid black or red, although the udder may be white. There have always been both red and black individuals in the population, and in the USA they are regarded as two separate breedsScotland
For some time before the 1800s, the hornless cattle in Aberdeenshire and Angus were called Angus doddies. Hugh Watson can be considered the founder of the breed; he was instrumental in selecting the best black, polled animals for his herd. His favorite bull was Old Jock, who was born 1842 and sired by Grey-Breasted Jock. Old Jock was given the number "1" in the Scottish Herd Book when it was founded. Another of Watson's notable animals was a cow, Old Granny, which was born in 1824 and said to have lived to 35 years of age and to have produced 29 calves. The pedigrees of the vast majority of Angus cattle alive today can be traced back to these two animals.United States
Red Angus and Black Angus. Black Angus is the most popular beef breed of cattle in the United States, with 324,266 animals registered in 2005.On May 17, 1873, George Grant brought four Angus bulls to Victoria, Kansas. He took the bulls to the fair in Kansas City where they were the topic of much conversation at a time when Shorthorns and Longhorns were the norm. The black hornless animals were often called "freaks" by those who saw them. The bulls were used only in crossbreeding and have no registered progeny today. However, their offspring left a favorable impression on the cattlemen of the time and soon more Angus cattle were imported from Scotland to form purebred herds.On November 21, 1883, the American Aberdeen Angus Association was founded in Chicago, Illinois,but the organization's name was shortened in the 1950s to the American Angus Association. The Association's first herd book was published on March 1, 1885. At this time both red and black animals were registered without distinction. However, in 1917 the Association barred the registering of red and other colored animals in an effort to promote a solid black breed.Red Angus cattle occur as the result of a recessive gene. Breeders collecting red cattle from black herds began the Red Angus Association of America in 1954. Other countries such as the United Kingdom and Canada still register both colors in the same herd book.

THE BUTCHER
A butcher is a person who may slaughter animals, dress their flesh, sell their meat or any combination of these three tasks. They may prepare standard cuts of meat, poultry, fish and shellfish for sale in retail or wholesale food establishments. A butcher may be employed by supermarkets, grocery stores, butcher shops and fish markets or may be self-employed.m
An ancient trade, whose duties may date back to the domestication of livestock, butchers formed guilds in England as far back as 1272. Today, many jurisdictions offer trade certifications for butchers. Some areas expect a three-year apprenticeship followed by the option of becoming a master butcher.

SLAUGHTER HOUSE
"HOME SWEET HOME"
Slaughterhouses act as the starting point of the meat industry, where stock come from farms/market to enter the food chain. They have existed as long as there have been settlements too large for individuals to rear their own stock for personal consumption.
Cattle (mostly steers and heifers, some cows, and even fewer bulls) are received by truck or rail from a ranch, farm, or feedlot.
Cattle are herded into holding pens.
Cattle are rendered unconscious by applying an electric shock of 300 volts and 2 amps to the back of the head, effectively stunning the animal,[10] or by use of a captive bolt pistol to the front of the cow's head (a pneumatic or cartridge-fired captive bolt). Swine can be rendered unconscious by CO2/inert gas stunning. (This step is prohibited under strict application of Halal and Kashrut codes.)
Animals are hung upside down by both of their hind legs on the processing line.
The carotid artery and jugular vein are severed with a knife, blood drains, causing death through exsanguination.
The head is removed, as well as front and rear feet. Prior to hide removal, care is taken to cut around the digestive tract to prevent fecal contamination later in the process.
The hide/skin is removed by down pullers, side pullers and fisting off the pelt (sheep and goats). Hides can also be removed by laying the carcase on a cradle and skinning with a knife.
The internal organs are removed and inspected for internal parasites and signs of disease. The viscera are separated for inspection from the heart and lungs, referred to as the "pluck." Livers are separated for inspection, tongues are dropped or removed from the head, and the head is sent down the line on the head hooks or head racks for inspection of the lymph nodes for signs of systemic disease.
The carcase is inspected by a government inspector for safety. (This inspection is performed by the Food Safety Inspection Service in the U.S., and Canadian Food Inspection Agency in Canada.)
Carcases are subjected to intervention to reduce levels of bacteria. Common interventions are steam, hot water, and organic acids.
Carcases (typically cattle and sheep only) can be electrically stimulated to improve meat tenderness.
Carcases are chilled to prevent the growth of microorganisms and to reduce meat deterioration while the meat awaits distribution.
The chilled carcase is broken down into primal cuts and subprimals for boxed meat unless customer specifies for intact sides of meat. Beef and horse carcases are always split in half and then quartered, pork is split into sides only and goat/veal/mutton and lamb is left whole
The remaining carcase may be further processed to extract any residual traces of meat, usually termed advanced meat recovery or mechanically separated meat, which may be used for human or animal consumption.
Waste materials such as bone, lard or tallow, are sent to a rendering plant. Also, lard and tallow can be used for the production of biodiesel or heating oil.
The wastewater, consisting of blood and fecal matter, generated by the slaughtering process is sent to a waste water treatment plant.
The meat is transported to distribution centers that then distribute to retail markets.
AGING
(dry/wet)
Dry-aged beef is beef that has been hung to dry for several weeks. After the animal is slaughtered and cleaned, either an entire half will be hung, or prime cuts (large distinct sections) will be placed in a cooler, also known as a "hot box". This process involves considerable expense, as the beef must be stored near freezing temperatures. Also, only the higher grades of meat can be dry aged, as the process requires meat with a large, evenly distributed fat content. For these reasons one seldom sees dry-aged beef outside of steak restaurants and upscale butcher shops. The key effect of dry aging is the concentration of the flavor.
The process changes beef by two means. First, moisture is evaporated from the muscle. This creates a greater concentration of beef flavor and taste. Second, the beef’s natural enzymes break down the connective tissue in the muscle, which leads to more tender beef.
Dry aging of beef is rare in super-markets in the United States today, due to the significant loss of weight in the aging process. It is found in steakhouses and certain restaurants.
The process of dry-aging usually also promotes growth of certain fungal (mold) species on the external surface of the meat. This doesn't cause spoilage, but actually forms an external "crust" on the meat's surface, which is trimmed off when the meat is prepared for cooking. These fungal species complement the natural enzymes in the beef by helping to tenderize and increase the flavor of the meat. The genus Thamnidia, in particular, is known to produce collagenolytic enzymes which greatly contribute to the tenderness and flavor of dry-aged meat.
Wet-aged beef is beef that has typically been aged in a vacuum-sealed bag to retain its moisture. This is the dominant mode of aging beef in the United States today. Wet-aging is popular because it takes less time (typically only a few days) and none of the weight is lost in the process. In contrast, dry-aging can take 15–28 days, and will see up to a third or more of the weight lost as moisture.
RIGOR MORTIS
Rigor mortis is one of the recognizable signs of death that is caused by a chemical change in the muscles after death, causing the limbs of the corpse to become stiff and difficult to move or manipulate.In humans it commences after about 3 hours, reaches maximum stiffness after 12 hours, and gradually dissipates until approximately 72 hours (3 days) after death. Heat sources such as fire can speed up the process of rigor mortis.
Biochemistry...
After death, respiration in organisms ceases to occur, depleting the corpse of oxygen used in the making of Adenosine triphosphate (ATP). ATP is no longer provided to operate the SERCA pumps in the membrane of the sarcoplasmic reticulum, which pump calcium ions into the terminal cisternae. This causes calcium ions to diffuse from the area of higher concentration (in the terminal cisternae and extracellular fluid) to an area of lower concentration (in the sarcomere), binding with troponin and allowing for crossbridging to occur between myosin and actin proteins.
Unlike normal muscle contractions, the body is unable to complete the cycle and release the coupling between the myosin and actin, creating a perpetual state of muscular contraction, until the breakdown of muscle tissue by digestive enzymes during decomposition.
Applications in industry...
Rigor mortis is very important in meat technology. The onset of rigor mortis and its resolution partially determines the tenderness of meat. If the post-slaughter meat is immediately chilled to 15°C (59°F), a phenomenon known as cold shortening occurs, where the muscle shrinks to a third of its original size. This will lead to the loss of water from the meat along with many of the vitamins, minerals, and water soluble proteins. The loss of water makes the meat hard and interferes with the manufacturing of several meat products like cutlet and sausage.
Cold shortening is caused by the release of stored calcium ions from the sarcoplasmic reticulum of muscle fibers in response to the cold stimulus. The calcium ions trigger powerful muscle contraction aided by ATP molecules. To prevent cold shortening, a process known as electrical stimulation is carried out, especially in beef carcasses, immediately after slaughter and skinning. In this process, the carcass is stimulated with alternating current, causing it to contract and relax, which depletes the ATP reserve from the carcass and prevents cold shortening.
Application in forensic pathology...
The degree of rigor mortis may be used in forensic pathology to determine the approximate time of death.
What Causes Rigor Mortis?
Chemistry of Muscle Fibers
By Anne Marie Helmenstine, Ph.D.
A few hours after a person or animal dies, the joints of the body stiffen and become locked in place. This stiffening is called rigor mortis. Depending on temperature and other conditions, rigor mortis lasts approximately 72 hours. The phenomenon is caused by the skeletal muscles partially contracting. The muscles are unable to relax, so the joints become fixed in place.
More specifically, what happens is that the membranes of muscle cells become more permeable to calcium ions. Living muscle cells expend energy to transport calcium ions to the outside of the cells. The calcium ions that flow into the muscle cells promote the cross-bridge attachment between actin and myosin, two types of fibers that work together in muscle contraction. The muscle fibers ratchet shorter and shorter until they are fully contracted or as long as the neurotransmitter acetylcholine and the energy molecule adenosine triphosphate (ATP) are present. However, muscles need ATP in order to release from a contracted state (it is used to pump the calcium out of the cells so the fibers can unlatch from each other). ATP reserves are quickly exhausted from the muscle contraction and other cellular processes. This means that the actin and myosin fibers will remain linked until the muscles themselves start to decompose.
Rigor mortis can be used to help estimate time of death. The onset of rigor mortis may range from 10 minutes to several hours, depending on factors including temperature (rapid cooling of a body can inhibit rigor mortis, but it occurs upon thawing). Maximum stiffness is reached around 12-24 hours post mortem. Facial muscles are affected first, with the rigor then spreading to other parts of the body. The joints are stiff for 1-3 days, but after this time general tissue decay and leaking of lysosomal intracellular digestive enzymes will cause the muscles to relax. It is interesting to note that meat is generally considered to be more tender if it is eaten after rigor mortis has passed.
