How have transgenic animals proved to be beneficial in production of biological products?

Solution
Biological products: Many human diseases are controlled by biological products. The transgenic animals which produce these products are introduced with DNA which codes for a particular product, such as human protein (α-Iantitrypsin) for treating emphysema. In 1997, the first transgenic cow (Rosie) was produced. She was capable of secreting human protein-enriched milk. The milk contained the human alpha-lactalbumin and was nutritionally a more balanced product for human babies than cow milk.
