ViaGen began by offering cloning to the livestock and equine industry in 2003, [20] and later as ViaGen Pets included cloning of cats and dogs in 2016. [21] ViaGen's subsidiary, start licensing, owns a cloning patent which is licensed to their only competitor as of 2018, who also offers animal cloning services. [22] (Viagen is a subsidiary of ...
Human proteins expressed in mammals are more likely to be similar to their natural counterparts than those expressed in plants or microorganisms. Stable expression has been accomplished in sheep, pigs, rats, and other animals. In 2009, the first human biological drug produced from such an animal, a goat, was approved.
All maintained healthy stats comparable to control cattle and reached reproductive maturity at the sound stage. [21] [22] Two of these cloned cattle successfully mated, each producing a healthy calf. [22] A purebred Hereford calf clone named Chloe was born in 2001 at Kansas State University's purebred research unit. This was Kansas State's ...

Consecutively, thousands of years of natural and human selection, genetic drift, inbreeding, and crossbreeding have contributed to the diversification of animal genetic resources and increased the variety of environments and production systems that livestock keeping takes place. Relatively few species have been domesticated; out of the world's ...
While noting that humans (along with elephants and whales) theoretically have the potential to live longer than most other mammals, de Magalhães said that every mammal is still living under ...
High fetal and neonatal death make the process very inefficient. Resulting cloned offspring are also plagued with development and imprinting disorders in non-human species. For these reasons, along with moral and ethical objections, reproductive cloning in humans is proscribed in more than 30 countries. [31] Most researchers believe that in the ...
