Editor's note: This Practice Builder is based on a presentation given by Larry Chase, dairy scientist at Cornell University, at the recent Cornell Nutrition Conference.


Nutritional strategies exist for reducing greenhouse-gas emissions from dairy cows.

Greenhouse-gas emissions may not be the primary focus of your clients these days, given the high cost of feed and their own economic survival. But there are efficiencies to be gained from optimizing crude protein levels in the ration, which can cut greenhouse emissions and also help your clients' bottom-line.
A key factor in reducing ammonia losses on a dairy farm is to balance rations and decrease nitrogen (N) excretion in manure, according to Larry Chase, dairy scientist at Cornell University. Manure N excretion increases with the higher-crude-protein rations, he said.

"A major nutritional variable that influences N use efficiency and potential ammonia emissions is the rumen balance of (rumen degradable protein) relative to requirements," he said.
Regarding methane, he said there are a number of strategies that can be used to alter emissions.

"These include using higher-quality forage, feeding higher-quality grain diets, using ionophores and the addition of various fats or oilseeds to rations."

A key consideration must be farm profitability and sustainability, he says.
