Pork cycle. A schematic diagram of the pork cycle. In economics, the term pork cycle, hog cycle, or cattle cycle [1] describes the phenomenon of cyclical fluctuations of supply and prices in livestock markets.

Feed conversion ratio (FCR) is the ratio of inputs to outputs; it is the inverse of "feed efficiency" which is the ratio of outputs to inputs. [ 2] FCR is widely used in hog and poultry production, while FE is used more commonly with cattle. [ 2] Being a ratio the FCR is dimensionless, that is, it is not affected by the units of measurement ...
