   Animal Variation Workshop NZ 2009  Minimize


Livestock Breeding for Greenhouse Gas outcomes
The 3 day workshop workshop funded by MAF and PGgRc was held in Wellington, New Zealand on March 3-5 2009 under the auspices of LEARN. There was Twenty-nine participants from 7 countries in attendance.

The workshop was the first opportunity to bring together animal genetics and animal methane researchers to discuss aspects of genetic improvement for enteric emissions. Many Opportunities and constraints to reducing emissions by genetic improvement of animals were identified.

Prediction of Methane Production from Dairy and Beef Cattle
Tuesday, January 22, 2008 (1691 reads)


 

Methane (CH4) is one of the major greenhouse gases being targeted for reduction by the Kyoto protocol. The focus of recent research in animal science has thus been to develop or improve existing CH4 prediction models to evaluate mitigation strategies to reduce overall CH4 emissions. Eighty-three beef and 89 dairy data sets were collected and used to develop statistical models of CH4 production using dietary variables.
