This Ontario farmer says he's cutting emissions one cow belch at a time

On a cold winter's day, the brown and white cattle munching on hay in the pasture stare, moo and poop like any other. 

But it's their burps that make them special, says Dave Braden, a small beef farmer in Puslinch, Ont., between Hamilton and Guelph. 

They're cattle bred to eat about 10 per cent less feed and therefore produce about 10 per cent less methane than the average bovine, he said. That means every time they belch, they're emitting less of the greenhouse gas into the atmosphere. 

"They look the same, and they act the same, but they're just more efficient," Braden said. 

The former Hamilton city councillor, who represented Flamborough in the early 2000s, said he's been "hooked" on efficiency for decades — he started with building an environmentally friendly home — and is now striving for his 26-animal herd to be among the most efficient, and lowest emitting, in Canada.

Not all of his animals eat 10 per cent less, but he's hoping to get there in about four years, he said. He purchases semen from a farmer in Alberta, whose bulls are among the most efficient Braden said he's ever encountered. Over time, each generation of his cattle become more and more efficient.

Braden's environmental passions started in the early 1970s with building energy efficient homes, including his own and then extending to livestock when he bought his first cow. 

Initially, Braden said he focused on breeding horned Hereford cows and bulls that would thrive on a free-range, grass-only diet. That means no grain, feedlots or machinery, lowering Braden's overall fossil fuel footprint, he said.

Braden took it a step further about 20 years ago, when he began breeding his cattle to be the efficient bovine they are today, he said. 

"I care about the environment a lot and I do like doing things a bit different," Braden said. 

"I get a bit of a charge out of trying new things that aren't in the book. This makes me feel like I'm looking after the land well and producing a good product." 

Methane is a "potent" greenhouse gas that's responsible for 30 per cent of global warming, says the federal government's website. Nearly 30 per cent of Canada's methane emissions come from the agricultural sector. 

Cattle are responsible for 86 per cent of the sector's methane, which they burp out as they digest food. Some methane is also released from manure.
