Milk of transgenic 'Cow Rosie' was nutritionally more balanced product for human babies than natural cow milk because it contained:
Human protein $\alpha$-1-antitrypsin
Human alpha-lactalbumin
Human insulin-like growth factor
Human enzyme Adenosine Deaminase (ADA)
Solution
Transgenic cow Rosie produced milk rich in Human protein $\alpha$-Lactalbumin which is easily digestible to babies with lactose intolerance.
$\rightarrow$ Such proteins which are produced in other organisms through DNA recombinant technology are called recombinant proteins.
