Microlivestock is a term coined for species that are inherently small as well as for breeds of cattle, sheep, goats, and pigs that are less than about half the size of the most common breeds. These miniature animals are seldom considered in the broad picture of livestock development, but they seem to have a promising future, especially in developing nations or wherever land is scarce. This book raises awareness of the potential of these small species, including microcattle, microsheep, various poultry, rabbits, rodents, deer, antelope, and lizards. It also strives to stimulate their introduction into animal research and economic development programs.
