Cold storage. Temperature is the most important factor influencing bacterial growth. Pathogenic bacteria do not grow well at temperatures under 3°C. Therefore, meat should be stored at temperatures that are as cold as possible. Refrigerated storage is the most common method of meat preservation. The typical refrigerated storage life for fresh meat is 5 to 7 days.
Freezer storage is an excellent method of meat preservation. It is important to wrap frozen meats closely in packaging that limits air contacts with the meat in order to prevent moisture loss during storage. The length of time meats are held at frozen storage also determines product quality. Under typical freezer storage of -18°C beef can be stored for 6 to 12 months, lamb for 6 to 9 months, pork for 6 months, and sausage products for 2 months.

Freezing. The rate of freezing is very important in maintaining meat quality, rapid freezing being superior. If meats are frozen slowly, large ice crystals form in the meat and rupture cell membranes. When this meat is thawed, much of the original moisture found in the meat is lost as juice flow from the meat. For this reason cryogenic freezing or other rapid methods of freezing meats are used at the commercial level to maintain maximal product quality. It is important to note, however, that freezing does not kill the microorganisms; they simply become dormant. When the meat is thawed, the spoilage continues where it left off.

Cow milk has been used by man from the earliest times to provide both fresh and storable nutritious foods. The nutritional value of milk is indicated by the fact that daily consumption of a quart (0,95 litre) of cows’ milk supplies an average man with approximately all the fat, calcium, phosphorus, and riboflavin, one-third of the vitamin A, ascorbic acid, and thiamine, one-fourth the calories; and with the exception of iron, copper, manganese, and magnesium, all the minerals needed daily. Considerable amounts of nicotinic acid and choline are also provided.

Domestication of animals is more than taming. Their habitat is restricted, protection assured, food supply maintained, and most important, breeding farm animals is done under human management and control.
In general animals have been domesticated for the following three purposes: as a source of food, clothing, etc, as assistants used in various human activities, or as pets.
The usefulness of animals domesticated may vary. For instance, European and many other peoples breed cows for obtaining milk and beef, but the Chinese do not milk cows, and Hindus do not eat beef.
