Please can I have some methane reducer?

Cartoon depicts the scene from Oliver Twist but here a cow labelled 'NZ' asks "Please Sir, can I have some?" US's Uncle Sam is laddling out Bovaer methane reducer feed supplement for livestock. Cows from other countries are gobbling down plenty. Cartoon is based on a decision by the United States to use Bovear, basically a supplement, as a way to reduce methane emission in cows. NZ is one of the few countries still awaiting approval to use Bovear.
