Nicola Schreurs – Animal nutrition and meat quality
Sarah kicked off defining carcass quality verses meat quality. Where classification characteristics associated with greater saleable meat yields and premium prices (weight, shape, fatness etc) verses how good the meat is. In regard to colour, palatability and nutritive values. Consumers
Ajmal Khan – Effect of nutrition on the development and performance of calves
Dr Ajmal Khan gave a very engaging talk on calf rearing. The talk began by setting the scene on the challenges around calf rearing and reviewed the current state of knowledge. Particular attention was given to colostrum management including the
Dr Emma Cuttance, Facial Eczema
Dr Emma Cuttance has been key in the recent research carried out in NZ for facial eczema (FE). Within her presentation, she walks through the impact of FE, the damage caused by FE going untreated, and the reliability of treatment
Dr Lance Baumgard, Inflammation
Lance kick started the session with an over view of the GIT, and the impact of how overall health can stem from the GIT. He discusses the thickness of the rumen which can be > 10 layers thick, compared the
David Pacheco – Options for abatement of enteric methane emissions from ruminants
During this session David covered the indirect and direct options for mitigating enteric methane. Indirect options include improving feed quality and animal health for improved animal efficiency and reduction in GHG . Direct interventions act directly in the rumen to
Andre Mazzetto – Life Cycle Assessment – the importance of feed in the footprint of animals
Lifecycle assessment (LCA) is a technique for assessing the environmental aspects and potential impacts associated with a product, system or service. In this session, Andre covered what different components make up an LCA and talked about the importance of accounting

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
