What Process Resulted in a Dramatic Increase in Milk Production

Question

What process resulted in a dramatic increase in milk production in modern dairy cows?
A) the insertion of beta carotene in the cow genome
B) the use of recombinant bovine growth hormone
C) frameshift mutations in the DNA of the cows
D) the use of gene guns to insert new genes into the cow mammary tissues

Accepted Answer

The use of recombinant bovine growth hormone (rBGH) is a process that resulted in a dramatic increase in milk production in modern dairy cows. rBGH is a genetically engineered hormone that is administered to cows to stimulate milk production. This hormone increases the levels of insulin-like growth factor (IGF-1) in cows, which in turn, stimulates milk production. Over the years, the use of rBGH has led to significant increases in milk production in dairy cows.
