As U.S. moves to cut greenhouse emissions from farms, new study finds big global challenge

By Virginia Gewin and Patrick Monahan

From cow burps to decaying food waste, agriculture is a major source of greenhouse gas emissions. Researchers estimate farms are responsible for about 13% of total global emissions, making it the world’s second-largest source, after energy production. And now that nations have committed to trying to hold global warming to no more than 2°C above pre-industrial levels, researchers and policymakers are looking for practical ways to cut agriculture’s contribution to climate change.

Keeping Dairy Goats on Rotational Pasture 24/7 to Reduce Internal Parasites

 By Eric Reuter

Rotational grazing can reduce the parasite load of goats, but this is difficult to accomplish with a dairy herd which needs to return to the same location every day for milking. Most dairy setups assume that the goats remain in a permanent shelter or barn overnight, adjacent to the milking area, and are only put out to pasture after milking and returned by evening. This means the goats are spending about half of their time in the same location and bedding, allowing problematic parasites to complete their life cycles and infect the herd.



Selecting Rams for Rangeland Production


 By Kathy Voth

 In western states, where almost half of U.S. sheep are produced, the Suffolk ram is commonly used as the “terminal sire” – an animal with the best genetics to sire lambs for meat production. However, concerns about the ability of Suffolk-sired lambs to survive from birth to weaning, and then to harvest, raised some doubts about the Suffolk’s value as a terminal sire.
