Lamb rearing in dairy sheep systems. Sue McCoard
Sue talks about the importance of good lamb rearing and its effects on lifetime performance of the lamb. This is a multi-factorial approach involving genetics, environment and people and discusses the year-round feeding program in a range of farming systems.
The sheep dairy industry and nutrition and management of dairy ewes, Sam Peterson
Sam Peterson has been involved in the NZ milking sheep industry for many years and through his involvement at Massey University. Sam provides some history as to where the industry has come from and the rapid growth we have seen
Can we have our cake and eat it too? – Designing systems that meet multiple bottom lines. Ian Williams
Nutrition is just one component of the wider farm system. Ian Williams provided a ‘big picture’ view of on-farm requirements around environmental requirements. The importance of profit remains central to all farm businesses when systems change to address future legislative

Can ruminant methane be reduced by genetic selection, vaccines or feeding seaweed? Garry Waghorn
Gary discussed three methodologies currently being worked on as mitigation strategies for methane reduction: Genetics Certain sheep have been identified as having low methane emisions. These are also sheep whtat are low yielding so there is a trade-off with performance.

Nitrogen and Feeds – David Pacheco, AgResearch
Farmers use Nitrogen (N) to increase forage yields and increase profitability, however, there has been increasing requirements to minimise environmental impact and for this reason N use on farms is under scrutiny. N that is not used in an animal
Enteric Methane and Feeds – Arjan Jonker, AgResearch
Methane (CH4) is mainly formed in the rumen (87-92%) by methanogens which utilise microbially hydrogen produced in the rumen during fermentation of ingested feed. CH4 from animals is measured via gas exchange using flux methods like respiration chambers and marker methods
