To establish a herd of genetically engineered pigs will require surgical operations on pigs to obtain eggs and insert embryos. Piglets will be "born" by extraction of the uterus, followed by killing of the sow. The piglets will then be kept in "bio-secure rooms" far from the fields, woods and puddles they naturally enjoy.
