Climate Researchers 'Potty Train' Peeing Cows

Research Institute for Farm Animal Biology reveals an urinating cow in a latrine pen in New Zealand.

Wellington, New Zealand:

Scientists say they’ve efficiently “potty skilled” cows to urinate in a delegated bathroom space as a part of a programme geared toward slashing greenhouse fuel emissions.

The staff of New Zealand and German researchers admitted the thought started as a joke however mentioned coping with cows’ nitrogen-rich liquid waste may have real long-term local weather advantages.

“If we may acquire 10 or 20 p.c of urinations, it might be ample to scale back greenhouse fuel emission and nitrate leaching considerably,” Auckland University’s Douglas Elliffe mentioned.

Elliffe mentioned the nitrogen in cow pee broke down into two downside substances over time — nitrous oxide, a potent greenhouse fuel, and nitrate, which collects in soil then leaches into rivers and streams.

Nitrous oxide accounts for about 5 p.c of world greenhouse fuel emissions and slightly below 10 p.c of New Zealand’s whole, in response to official information, with greater than half linked to livestock.

Researcher Lindsay Matthews mentioned that the thought of bathroom coaching cows so their urine may very well be captured and handled first occurred to him when a radio host was interviewing him in 2007 and made a throwaway joke on the matter.

“People’s response is ‘loopy scientists’ however truly the constructing blocks are there,” he mentioned.

Working with colleagues in Germany, the scientists used meals rewards to coach 16 calves to urinate in a latrine pen, saying the outcomes have been just like these you’ll count on from a three-year-old youngster.

Elliffe mentioned the analysis, printed this week within the journal Current Biology, offered “proof of idea” that bathroom coaching cows was doable.

He mentioned the problem was to upscale the idea to coach giant herds and adapt it for cows in environments equivalent to New Zealand, the place the animals reside outdoor fairly than spending most of their time in barns.

Farming creates about half of New Zealand’s greenhouse emissions, largely within the type of methane and nitrous oxide.

Unusually for a developed nation, New Zealand’s farm-reliant financial system means methane accounts for about 43.5 p.c of  the nation’s emissions, nearly equal to the quantity of carbon dioxide generated by sources equivalent to fossil fuels.

The South Pacific nation has quite a few analysis initiatives inspecting doable options, equivalent to breeding low-methane emitting livestock, utilizing feeds that scale back emissions and even vaccinating animals in order that they produce much less dangerous gases.
