The cattle cycle is the approximately 10-year period in which the number of U.S. beef cattle is alternatively expanded and reduced over several consecutive years in response to perceived changes in profitability by producers. Generally, low prices occur when cattle numbers (or beef supplies) are high, precipitating several years of herd ...
This approach is based on regression models developed for determining efficiency of feed use for weight gain during a standardized growth trial in growing beef cattle. [ 3 ] It was inspired by Koch's observations of the differences in how a maintained body weight and an increasing body weight affect the feeding of cattle.

For dairy cows, for example, the output is milk, whereas in animals raised for meat (such as beef cows, [1] pigs, chickens, and fish) the output is the flesh, that is, the body mass gained by the animal, represented either in the final mass of the animal or the mass of the dressed output. FCR is the mass of the input divided by the output (thus ...
Most beef cattle are mated naturally, whereby a bull is released into a herd of cows approximately 55 days after the calving period, depending on the cows' body condition score (BCS). If it was a cow's first time calving, she will take longer to re-breed by at least 10 days. [ 4 ]
The cattle industry takes the position that the use of growth hormones allows plentiful meats to be sold for affordable prices. [24] Using hormones in beef cattle costs $1.50 and adds between 40 and 50 lb (18 and 23 kg) to the weight of a steer at slaughter, for a return of at least $25. [25]
The meat of adult cattle is known as beef, and that of calves as veal. Other body parts are used as food products, including blood, liver, kidney, heart and oxtail. Approximately 300 million cattle, including dairy animals, are slaughtered each year for food. [99] About a quarter of the world's meat comes from cattle. [100]
Within the American beef cattle industry, the older term beef (plural beeves) is still used to refer to an animal of either sex. Some Australian, Canadian, New Zealand and British people use the term beast. [11] Cattle bred specifically for milk production are called milking or dairy cattle; [1] a cow kept to provide milk for one family may be ...
