Crossbreeding involves breeding animals of two different breeds to produce crossbred and breeding decides which males should be mated with which females. When breeds and breeding systems (and other aspects) are thought of as componen ts of a production system, this by default helps provide for balanced considerations. The advantages and disadvantages of the different breeding systems used in rabbits are discussed in this chapter. But fewer women had correct knowledge about breeding, feeding and management Other breeds have evolved by crossing among older established breeds until a new type has emerged.
