Animal Variation Workshop NZ 2009
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.
