Abstract

Fertility in dairy cows has decreased during the past 50 years and current management procedures have done little to rectify this situation. Following intense selection for increased milk production, there are significantly more problems in establishing pregnancy at the appropriate time. In recent years, major strides have been made in the development of new embryo-based biotechnologies, including in vitro embryo production, ovum pick-up, cryopreservation of gametes and embryos, cloning and sexing of gametes. The objectives of this paper are to review current progress relating to embryo-based technologies in cattle.
