Abstract
A_rapidly ‘exploding’ world population and an increasing consumer preference for leaner cuts of meat demand rapid improvement in the efficiency of rates of gain in our beef cattle. The development of larger animals with leaner carcasses containing more protein and less fat seems imperative. Accomplishment of these goals within a minimum time requires the use of artificial insemination techniques and maximal utilization of semen from highly selected bulls transmitting the desired characteristics. However, progress in applying artificial insemination to beef cattle has been extremely slow because of the practical problems of carrying out insemination under range conditions and the low conception rates frequently encountered in artificially bred beef animals. Clearly, the development of oestrous cycle synchronization which can be used under practical management conditions could play a major role in facilitating the use of artificial insemination and improved selection techniques in the beef cattle industry. It seems clear that the greatest potential application of artificial cycle regulation is in beef cattle.
