Watch FMovies. Cattle breeding leaves less and less room for chance or empiricism. While focusing on the relationship between the farmer and his cows, Patricia Mazuy takes us on the great merry-go-round of animal selection and the quest for performance. With precision and humor, this masterful film introduces us to genetics, testing, artificial insemination, "in vitro" fertilization, cloning and other embryo transfers in the French cattle breeding world.
