Milk Goes ‘Green’: Today’s Dairy Farms Use Less Land, Feed and Water

12.06.2009
Dairy genetics, nutrition, herd management and improved animal welfare over the past 60 years have resulted in a modern milk production system that has a smaller carbon footprint than mid-20th century farming practices, says a Cornell University study in the Journal of Animal Science (June 2009).

“As U.S. and global populations continue to increase, it is critical to adopt management practices and technologies to produce sufficient high-quality food from a finite resource supply, while minimizing effects upon the environment,” says Jude Capper, lead author and a recent Cornell post-doctoral researcher working with Dale E. Bauman, Cornell Liberty Hyde Bailey Professor of Animal Science.

The study, “The Environmental Impact of Dairy Production: 1944 compared with 2007,” shows that the carbon footprint for a gallon of milk produced in 2007 was only 37 percent of that produced in 1944. Improved efficiency has enabled the U.S. dairy industry to produce 186 billion pounds of milk from 9.2 million cows in 2007, compared to only 117 billion pounds of milk from 25.6 million cows in 1944. This has resulted in a 41 percent decrease in the total carbon footprint for U.S. milk production.

Efficiency also resulted in reductions in resource use and waste output. Modern dairy systems only use 10 percent of the land, 23 percent of the feedstuffs and 35 percent of the water required to produce the same amount of milk in 1944.
Similarly, 2007 dairy farming produced only 24 percent of the manure and 43 percent of the methane output per gallon of milk compared to farming in 1944.

Joining Capper and Bauman on the paper is Roger A. Cady, Cornell ’74, MS ’77, PH.D. ‘80, a scientist at Elanco.

Research fund were provided to Bauman as a Liberty Hyde Bailey Professor and to the Cornell Agricultural Experiment Station. Capper has recently joined the faculty at Washington State University as assistant professor.

The study was first published in the Journal of Animal Science online in March 2009. It is available at: http://jas.fass.org/cgi/content/abstract/jas.2009-1781v1.

Im Focus: Data use draining your battery? Tiny device to speed up memory while also saving power

The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.

Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...

Im Focus: An energy-efficient way to stay warm: Sew high-tech heating patches to your clothes

Personal patches could reduce energy waste in buildings, Rutgers-led study says

What if, instead of turning up the thermostat, you could warm up with high-tech, flexible patches sewn into your clothes - while significantly reducing your...

Im Focus: Lethal combination: Drug cocktail turns off the juice to cancer cells

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.

The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...

Im Focus: New Foldable Drone Flies through Narrow Holes in Rescue Missions

A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.

Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
