[Artificial reproduction in cattle]

In the first part of the present review paper, not only the current procedures making possible artificial reproduction in cattle are stated, but also the limitations of the methods available for superovulation and sexing, low-temperature preservation and transfer of embryos. In the second part, alternative procedures are reviewed, which may be used to increase the number of embryos per dam to a further extent by methods other than superovulation. Finally, the practical use of these recently acquired methods in breeding and animal products is described.
