The use of growth promoting hormones in North American beef cows not only profits beef producers, it also benefits consumers and the environment. This is the remarkable conclusion of a new report by the Hudson Institute Center For Global Food Issues in the US.
Less land needed
The
report states that comparing conventional beef production to an alternative
grass-based beef production system using an economic/production model created by
scientists at Iowa State University shows that growth promoting hormones and
ionophores decrease the land required to produce a pound of beef by two thirds,
with fully one fifth of this gain resulting from growth enhancing
pharmaceuticals. Whereas grass-based organic beef requires more than 5 acre-days
to produce a pound of beef, less than 1.7 acre days are needed in a grain-fed
feedlot system using growth promotants.
Less greenhouse
gases
According to the report, grain feeding combined with growth
promotants also results in a nearly 40% reduction in greenhouse gases (GHGs) per
pound of beef compared to grass feeding (excluding nitrous oxides), with growth
promotants accounting for fully 25% of the emissions reductions.
