Downer (animal)
A downer is an animal, usually livestock, that cannot stand on its own and therefore is to be killed. A downed animal, one that is unable to stand, is not necessarily a downer. Causes The animal's inability to stand may be caused by illness or injury. In nearly all cases it is considered by most farmers to be both humane and cost-effective to kill the animal when it becomes a downer, rather than keeping it alive and unhealthy. Once killed, and depending on how the animal became a downer and how it was killed, the animal may then be incinerated, buried, rendered, or slaughtered. Because of mad cow disease, the slaughter of downer cattle is a topic of great concern. There are many possible reasons for an animal staying down, including: *Mastitis * Metritis *Hypomagnesaemia * Postparturient Hypocalcemia *Ketosis *Dystocia **Nerve damage **Pelvic fracture *Long bone fracture *Neurological disease Use of certain animal feed additives has been linked to downers such as the use o ...

Long Bone
The long bones are those that are longer than they are wide. They are one of five types of bones: long, short, flat, irregular and sesamoid. Long bones, especially the femur and tibia, are subjected to most of the load during daily activities and they are crucial for skeletal mobility. They grow primarily by elongation of the diaphysis, with an epiphysis at each end of the growing bone. The ends of epiphyses are covered with hyaline cartilage ("articular cartilage"). The longitudinal growth of long bones is a result of endochondral ossification at the epiphyseal plate. Bone growth in length is stimulated by the production of growth hormone (GH), a secretion of the anterior lobe of the pituitary gland. The long bone category includes the femora, tibiae, and fibulae of the legs; the humeri, radii, and ulnae of the arms; metacarpals and metatarsals of the hands and feet, the phalanges of the fingers and toes, and the clavicles or collar bones. The long bones of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meat Packing
The meat-packing industry (also spelled meatpacking industry or meat packing industry) handles the slaughtering, processing, packaging, and distribution of meat from animals such as cattle, pigs, sheep and other livestock. Poultry is generally not included. This greater part of the entire meat industry is primarily focused on producing meat for human consumption, but it also yields a variety of by-products including hides, dried blood, protein meals such as meat & bone meal, and, through the process of rendering, fats (such as tallow). In the United States and some other countries, the facility where the meat packing is done is called a ''slaughterhouse'', ''packinghouse'' or a ''meat-packing plant''; in New Zealand, where most of the products are exported, it is called a ''freezing works''. An abattoir is a place where animals are slaughtered for food. The meat-packing industry grew with the construction of railroads and methods of refrigeration for meat preservation. Rail ...

Food
Food is any substance consumed by an organism for Nutrient, nutritional support. Food is usually of plant, animal, or Fungus, fungal origin and contains essential nutrients such as carbohydrates, fats, protein (nutrient), proteins, vitamins, or Mineral (nutrient), minerals. The substance is Ingestion, ingested by an organism and assimilated by the organism's Cell (biology), cells to provide energy, maintain life, or stimulate growth. Different species of animals have different List of feeding behaviours, feeding behaviours that satisfy the needs of their metabolisms and have evolved to fill a specific ecological niche within specific geographical contexts. Omnivore, Omnivorous humans are highly adaptable and have adapted to obtaining food in many different ecosystems. Humans generally use cooking to prepare food for consumption. The majority of the food energy required is supplied by the industrial food industry, which produces food through Intensive farming, intensive agricu ...

Bovine Spongiform Encephalopathy
Bovine spongiform encephalopathy (BSE), commonly known as mad cow disease, is an incurable and always fatal neurodegenerative disease of cattle. Symptoms include abnormal behavior, trouble walking, and weight loss. Later in the course of the disease, the cow becomes unable to function normally. There is conflicting information about the time between infection and onset of symptoms. In 2002, the World Health Organization suggested it to be approximately four to five years. Time from onset of symptoms to death is generally weeks to months. Spread to humans is believed to result in variant Creutzfeldt–Jakob disease (vCJD). , a total of 233 cases of vCJD had been reported globally. BSE is thought to be due to an infection by a misfolded protein, known as a prion. Cattle are believed to have been infected by being fed meat-and-bone meal that contained either the remains of cattle who spontaneously developed the disease or scrapie-infected sheep products.

Federal Meat Inspection Act
The Federal Meat Inspection Act of 1906 (FMIA) is an American law that makes it illegal to adulterate or misbrand meat and meat products being sold as food, and ensures that meat and meat products are slaughtered and processed under strictly regulated sanitary conditions. These requirements also apply to imported meat products, which must be inspected under equivalent foreign standards. United States Department of Agriculture (USDA) inspection of poultry was added by the Poultry Products Inspection Act of 1957 (PPIA). The Food, Drug, and Cosmetic Act authorizes the Food and Drug Administration (FDA) to provide inspection services for all livestock and poultry species not listed in the FMIA or PPIA, including venison and buffalo. The Agricultural Marketing Act authorizes the USDA to offer voluntary, fee-for-service inspection services for these same species. Historical motivation for enactment The original 1906 Act authorized the Secretary of Agriculture to inspect and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commerce Clause
The Commerce Clause describes an enumerated power listed in the United States Constitution ( Article I, Section 8, Clause 3). The clause states that the United States Congress shall have power "to regulate Commerce with foreign Nations, and among the several States, and with the Indian Tribes". Courts and commentators have tended to discuss each of these three areas of commerce as a separate power granted to Congress. It is common to see the individual components of the Commerce Clause referred to under specific terms: the Foreign Commerce Clause, the Interstate Commerce Clause, and the Indian Commerce Clause. Dispute exists within the courts as to the range of powers granted to Congress by the Commerce Clause. As noted below, it is often paired with the Necessary and Proper Clause, and the combination used to take a more broad, expansive perspective of these powers. During the Marshall Court era (1801–1835), interpretation of the Commerce Clause gave Congress jurisdiction o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
