Precision Feeding: Greenhouse Gases and Water Quality

This is the roof of one of the greenhouses used by the Departments of Entomology and Plant Pathology. This view made me think about cows. And greenhouse gases and water quality. Bear with me, it will make sense.

We've been working on a story about precision feeding of dairy cows. One of the goals is to reduce greenhouse gas emissions from cows and better control water quality. Dr. Terry Etherton, Distinguished Professor of Animal Nutrition, gives a great overview of the challenges and opportunities in this area on his blog post titled:

Agriculture's Contribution to Greenhouse Gas Emissions

And there is a good description of how precision feeding can help with water quality in a Penn State Live posting called:

Precision feeding of livestock shows promise for water quality

Photographs are curious things. They don't always represent what you think they do.
