It isn't.
Agriculture accounted for an estimated emission of 5.1 to 6.1 GtCO2-eq/yr in 2005 (10-12% of total global anthropogenic emissions of greenhouse gases (GHGs)). (IPCC AR4[0], slightly revised to 5.0 to 5.8 GtCO2eq/y in AR5)
That's all agriculture, including livestock, this (IPCC AR5[1]) is just "cow farts":
Enteric Fermentation. Global emissions of this important category
grew from 1.4 to 2.1 GtCO2eq/yr between 1961 and 2010, with average annual growth rates of 0.70% (FAOSTAT, 2013).

Here's a 51% estimate, trumping everything else. http://www.worldwatch.org/node/6294 http://www.worldwatch.org/node/6294 No one can say with certainty. Although, raising 100 billion animals yearly, most of them having over 250lbs, I'd say it's pretty close for CO2. When it comes to methane, cow farts are 65% of our methane emissions. http://www.fao.org/docrep/010/a0701e/a0701e00.htm http://www.fao.org/docrep/010/a0701e/a0701e00.htm
