In 2015, the European Union voted to ban the cloning of farm animals (cattle, pigs, sheep, goats, and horses), and the sale of cloned livestock, their offspring, and products derived from them, such as meat and milk. The ban excluded cloning for research, and for the conservation of rare breeds and endangered species.
This technique is currently the basis for cloning animals (such as the famous Dolly the sheep), [30] and has been proposed as a possible way to clone humans. Using SCNT in reproductive cloning has proven difficult with limited success. High fetal and neonatal death make the process very inefficient. Resulting cloned offspring are also plagued ...
Animals are generally much harder to transform and the vast majority are still at the research stage. Mammals are the best model organisms for humans. Livestock is modified with the intention of improving economically important traits such as growth rate, quality of meat, milk composition, disease resistance, and survival.
Scientists have cloned the first rhesus monkey, a breakthrough that could help advance medical research but has drawn criticism from an animal welfare group. New cloned monkey species highlights ...
Genetically modified animals are animals that have been genetically modified for a variety of purposes including producing drugs, enhancing yields, increasing resistance to disease, etc. The vast majority of genetically modified animals are at the research stage while the number close to entering the market remains small.

The world’s first cloned black-footed ferret has given birth in a historic first for conservationists. Antonia the ferret successfully delivered two healthy kits after mating with Urchin, a ...
Human cloning is the creation of a genetically identical copy of a human. The term is generally used to refer to artificial human cloning, which is the reproduction of human cells and tissues. It does not refer to the natural conception and delivery of identical twins. The possibility of human cloning has raised controversies. These ethical ...
Starbuck II, a clone of Holstein breeding bull Hanoverhill Starbuck, was born by Caesarean section on 7 September 2000. It was one of the first animals cloned for commercial purposes. [17] [18] In 2000, Texas A&M University cloned a Black Angus bull named 86 Squared, after cells from his donor, Bull 86, had been frozen for 15 years. Both bulls ...
