Bovine Growth Hormone (rBGH)
engineered copy of a hormone which cows naturally produce. A 10-15% increase in
milk production can result from the injection of rBGH. The Food and Drug
Administration approved rBGH for use in cows in late 1993 and its uses has been
standard since 1994. Opponents argue that its use is harmful to cows, lessens
the nutritional value of milk, and threatens small family-owned dairy farms.
