According to research from CornellUniversity, recombinant bovine somatotropin allows more milk from fewer cows, which saves feedstuffs, reduces cropland and releases less methane into the atmosphere.

The research found that, compared to a non-supplemented population, giving rbST to one million cows would enable the same amount of milk to be produced using 157,000 fewer cows. The nutrient savings would be more than 541,000 tons of corn and more than 174,000 tons of soybeans. Producers could reduce cropland use and reduce 2.3 million tons of soil erosion annually.
