In vitro fertilization in cattle: a review.

Abstract

In vitro maturation and fertilization of cattle oocytes and subsequent in vitro culture of zygotes and embryos is discussed in the context of recent encouraging data. Mass production of embryos produced in this way in the future will have a great impact on animal production and animal breeding plans, for example the so-called MO-ET (multiple ovulation and embryo transfer) plan which aims at establishing nucleus breeding herds.
