NZARN are very grateful for the support of Biomin.
Helwi presented a piece of work he has been a part of that used modelling to look into environmental impact of grazing dairy systems and their profitability across a number of different scenarios. The same farm parameters were used for each scenario but with cow size, genetic potential and concentrate inputs varied across the scenarios
This presentation by Michael Shallcrass gives a comprehensive yet succinct explanation of the Co-Operative Difference, a framework on which producers are incentivised to manage environmental, social and governance standards in line with Co-operative expectations. Of interest to members of the NZARN is the focus on winter grazing management, and the framework around nutrition, welfare and
Dr. Emma Cuttance from VetEnt shares the latest New Zealand research information that has been carried out for the passed several years focusing on facial eczema. She showcases the impact of GGT levels on milk production and the risk of high GGT levels in consecutive years. Emma shares the impact of zinc delivery methods on
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. Sue discusses natural versus artificial rearing and the key feeding phases from liquid onto solid
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 in the last few years. This includes the types of farming systems, breeds and the
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 requirements. Ian demonstrated how alternate land uses may feature in the future including annual maize
Management for improved fertility and lifetime productivity in grazing dairy cows: latest NZ research – Claire Phyn, Dairy NZ
Claire Phyn, senior scientist at DairyNZ presented about an 8 year research programme funded by MBIE and NZ dairy farmers through DairyNZ Inc. It aimed to provide management and genetic solutions to improve cow health, fertility and longevity. Claire reported about 1. Effect of carbohydrate type (starch vs fibre) on reproduction 2. Hyperketonaemia (subclinical ketosis) and 3. Feeding synthetic zeolite pre-calving
Interpretation of blood and liver macro mineral results. How useful for nutritionists? Richard Laven SoVS, Massey University
Interpretation of blood and liver results.
Ketosis is a metabolic challenge that can occur for a number of reasons. Ian Sawyer lead a detailed discussion on these metabolic changes that occur over the transition period, how ketosis can be an outcome and how to mitigate ketosis. Ian dived into the factors that can influence dry matter intake post calving can come
