Rat is the most common transgenic animal used in research due to short reproduction cycle. Transgenic pigs are used as a source of organs for transplants. Dolly, the sheep is the first transgenic animal. Transgenic rabbits are used to produce recombinant human C12 esterase inhibitor. Some other transgenic animals that have been produced are cow, goats, fish, etc. These animals are used to produce more protein in milk and meat, disease resistance, good quality wool and improvement in genetic traits.
