Amy has been involved with the development of new indexes for Zoetis’ commercial beef heifer genomic evaluation and tailoring this evaluation to fit the New Zealand beef farming model. Having been involved with family relatives Angus stud breeding operation, as well as having had the opportunity to experience various parts of the beef supply chain both here in New Zealand as well as Australia and the UK, Amy has a thorough knowledge of areas for increased productivity and profit margin for beef farmers.

Unlocking greater profit potential in beef cattle by understanding and utilising genetic tools available | Wednesday 23 June 12:00pm | The veterinarian’s traditional role puts them in a prime place to collect DNA samples during on farm processes and then use DNA-based data both to investigate issues that maybe impacting herd performance and help promote positive production traits within a beef herd. The data genetic testing and tools bring to a cattle operation are only worthwhile if they are used correctly. In New Zealand these tools include parentage, the use of BREEDPLAN Estimated Breeding Values and, more recently, genomic predictions for commercial beef females.

Andrew Dowling

Andrew is studying the economic cost of liver fluke on the West Coast for completion of a PhD. This has involved sampling of milk, serum and faeces to assess liver fluke infection and the impact on milk production on farms supplying Westland Milk Products.

Prevalence of Liver Fluke on the West Coast | Thursday 24 June 8:00am | Bulk milk samples from herds supplying Westland Milk Products were analysed in the autumn and spring of consecutive lactations to determine the occurrence of liver fluke infection with 369 sampled on both occasions. GIS mapping of the farm locations indicated geographic grouping of farms with more severe fluke infestations. A short survey reported farmers awareness of liver fluke and drenching practices. This study indicates fasciolosis is common in this region with a disturbing number with a high prevalence in their herds.

Reproductive productivity of red deer hinds: identifying and reducing wastage | Wednesday 23 June 11:00am | Red deer hinds have long breeding lives (>10 years) and are capable of successfully rearing a singleton calf annually following puberty at 16 months of age. However, farmed herds in NZ seldom achieve the biological potential of their breeding hind herds due to various forms of reproductive wastage occurring at different times during the annual reproductive cycle. This paper describes the outcomes of studies conducted over 40 years on identifying the nature and causes of reproductive wastage in red deer herds, and discusses options for minimising such wastage to improve overall reproductive outcomes on NZ farms. It principally focusses on puberty failure, hind conception rates, foetal mortality and neonatal mortality.

Kathryn McRae

Kathryn is a scientist in the Animal Genomics team at AgResearch Invermay. Both her Masters (University of Otago/AgResearch) and PhD (Dublin City University/Teagasc) research focussed on investigating variation in the sheep genome controlling resistance to gastrointestinal nematodes. She currently works on a range of projects, including understanding the genetic basis of disease, including gastrointestinal nematode infection, facial eczema and pneumonia in sheep. This research works to harness the natural variation in the population to work towards breeding animals which are less reliant on chemical inputs.

Genetics as a tool for parasite management | Thursday 24 June 1:30pm | Current parasite control in sheep relies heavily on the use of anthelmintic treatment; the increasing prevalence of anthelmintic resistance in sheep nematodes throughout the world suggests that this strategy is unsustainable. Sustainable, long-term management of parasites requires an integrated control program, and breeding sheep with an increased ability to resist infection is an important part of this strategy. This presentation will discuss lessons learned from 25 years of research into breeding for parasite resistance in New Zealand sheep, including how we measure resistance, what goes into breeding values and indexes, the relationship with dag score, and whether it is it more appropriate to select animals adapted to a specific environment.
