ASSISTED BREEDING Artificial Insemination Estrous Cycle Control Embryo Transfer / Oocyte Transfer In Vitro Fertilization Cloning - Embryo Splitting - Nuclear Transfer Semen Sexing Gene Splicing

ADVANTAGES AND CONSIDERATIONS OF ARTIFICIAL INSEMINATION »Increase production »Prove more sires »Eliminate danger and expense of keeping a male »Reduce the number of males needed »Control disease »Increase sire life »Reduce injuries »Aid fertility control »Requires better identification »Aids specific genetic selection »Reduce sire cost
