Detailed explanation-1: -DNA microinjection, the first technique to prove successful in mammals, was first applied to mice (Gordon and Ruddle, 1981) and then to various other species such as rats, rabbits, sheep, pigs, birds, and fish.
Detailed explanation-2: -Transgenesis. In 1985 the first transgenic pigs were produced by injecting copies of human growth hormone genes into the pronuclei of newly fertilised eggs (Hammer et al. 1985). The technique was subsequently used in several studies (Pursel et al.
Detailed explanation-3: -Transgenic farm animals are also being explored as a means to produce large quantities of complex human proteins for the treatment of human disease. Such therapeutic proteins are currently produced in mammalian cell-based reactors, but this production process is expensive.
