Heat stress on dairy cows not only decreases the amount of milk produced but also the fat and protein content, doubling the economic losses.

New climate-controlled animal respiration stalls in CALS – the only ones currently operating in the U.S. – will allow researchers to measure, verify and monitor methane and other gas emissions from cows.

Methane is one of the greenhouse gasses responsible for climate change, and it is 25 times more potent than carbon dioxide as a driver of global warming. At the same time, 14.5% of methane emissions each year come from ruminants such as cows...

For over 20 years, Cornell CALS’ Nutrient Management Spear Program has helped dairy farms responsibly manage manure to meet crop nutrient needs while improving farm profitability and sustainability. Key to this success is the whole-farm nutrient...

This summer, visitors to Ithaca’s Sciencenter, a hands-on children’s museum, took part in a special exhibit made possible by a new collaboration between the museum, the State University of New York College at Cortland and Cornell’s Department of...

A new open-source computer model being developed by a Cornell-led interdisciplinary team will simulate production and quantify the environmental effects of management decisions made on dairy farms. The Ruminant Farms Systems Model project is...
