| 9.30am | Pain relief use and tailing weights in merino lambs | Jamie Foxley As increasing demand for pain relief at tailing/docking is faced, a variety of approaches have been trialed and adopted on fine-wool farms. Injectable and oral analgesics are weight dependent. There is a lack of data detailing merino lambs' weights at tailing. In 2025 Vetlife practitioners surveyed a number of Otago high-country farms at tailing and collected information on weights, ages and pain relief practices used. We also collected coarse-bred lamb weights in South Canterbury. We will discuss the results of this survey and observations from tailing visits and analgesic use. | Room 503 Level 5 |

| 10.25am | Further investigation into rear rub injuries in deer at slaughter | Jane Morgan This study investigates risk factors for rear rub injuries in deer. It was undertaken using data from all the deer slaughtered at a single plant during the period of January to May 2024 that corresponded to the highest incidence of injuries in the previous study. The findings indicate that further investigation is needed into the management of the transport phase of deer to processing premises, particularly of stags, to identify modifiable management factors to aid in control of deer rear rub injuries. | Room 503 Level 5 |

| 1.30pm | The effect of prenatal anthelmintic drugs on the behaviour of ewes and their new-born lambs | Melissa Hempstead Persistent macrocyclic lactone (ML) anthelmintics are commonly administered to pregnant ewes, yet their effects on neonatal lamb behaviour are poorly understood. This study investigated the behavioural effects of prenatal exposure to persistent MLs. Sixty twin-bearing ewes were assigned to moxidectin, a controlled-release abamectin/albendazole treatment, or untreated controls. Ewe and lamb behaviours were monitored for three hours post-parturition. Abamectin/albendazole had no detectable effects, whereas lambs born to moxidectin-treated ewes tended to show delayed head shaking and attempts to stand. These findings suggest prenatal moxidectin exposure may influence early neonatal behaviour, with potential implications for lamb vigour and survival. | Room 503 Level 5 |
| 2pm | Control of Haemonchus in ruminants through vaccination | Saleh Umair Haemonchus contortus is one of the most significant and pathogenic gastrointestinal nematode parasites infecting ruminants worldwide, and the rapid emergence of anthelmintic resistance poses a major challenge to its control. The present study investigates the biological control of H. contortus through vaccination. Young lambs and calves were immunised with a recombinant vaccine, resulting in a significant reduction in faecal egg output and adult worm burdens in vaccinated animals compared with controls. Vaccine efficacy was evaluated under both controlled indoor conditions and field-based trials, demonstrating consistent protective effects across experimental settings. | Room 503 Level 5 |
| 2.30pm | Larval heat mapping and resistance risk in the real world | Ryan Luckman The DAGI (Drench And Grazing Integration) tool launched in December 2025, providing New Zealand sheep farmers with paddock-level heat maps predicting larval contamination and anthelmintic resistance risk. Adapted from Australia's Turned Worm lifecycle model and integrated with AgResearch's Q-Graze intake predictions, DAGI models four nematode species across susceptible and resistant populations. This presentation reports on the first six months of field use across beta farms, comparing model predictions against farmer-inputted faecal egg count results and documenting changes in grazing and drenching decisions. Findings assess model accuracy under real-world conditions and the tool's influence on parasite management behaviour. | Room 503 Level 5 |

| 4pm | From fungus to faeces: new insights into facial eczema | Cara Brosnahan Facial eczema is a major welfare and productivity challenge for New Zealand livestock. The Eliminating Facial Eczema Impacts programme is investing in practical, farmer focused solutions. The disease is caused by a toxin producing fungus that is spreading into new regions as the climate warms. A three-year epidemiological study has just been completed, showing FE spores are consistently found as far south as Otago. Through research, diagnostics, risk mapping, and new tools, the programme aims to support farmers, vets, and rural professionals to better manage FE and reduce its long term impacts. Shared talk with Large Animal Veterinary Technician stream | Room 503 Level 5 |
| 4.30pm | Spore counting methods. How, when and why? | Sarah Hurst We have many diagnostic tools at our disposal for evaluating the the potential risk of Facial Eczema and the damage being caused by the sporidesmin toxin when ruminants ingest the Pithomyces chartarum Fungus. I'd like to take some time to remind our technicians of the importance of timing with this disease, how to use which diagnostics and when. How can we best support or clinics, vets and farmers to add value for each stakeholder while also supporting and helping to improve the welfare of the animals we work so closely with?

| 7am | Registration opens | Level 3 |
| 8am | Modern diagnostics for modern parasite challenges | Cara Brosnahan Gastrointestinal nematodes are becoming harder to manage as drench resistance rises - making fast, accurate diagnostics essential. New multiplex real time PCR tests have been developed to identify species within three working days, replacing slow larval cultures and giving farmers clearer, earlier information for treatment decisions. In parallel, molecular research is targeting resistance biomarkers in key Trichostrongylus species to understand how resistance develops and how it can be detected on farm. Together, these tools aim to improve parasite control, reduce ineffective drenching, and support vets and farmers with sharper, evidence based decisions in an increasingly challenging parasite landscape. | Room 503 Level 5 |

| 10.50am | Improving information flow from processors to producers benefits the industry | Stephen Yearwood | Room 503 Level 5 |
| 11.10am | Unwanted pregnancies in lambs | Rajiv Balbharan Unwanted pregnancies in ewe lambs/hoggets occur every season in New Zealand. This talk is presented from the perspective of a veterinarian based at the meat works. The presentation includes a look into the animal welfare consequences of these pregnancies, a survey with sheep farmers and their thoughts, and a preliminary insight into some production data collected from four different meat works in the South Island. | Room 503 Level 5 |
| 11.40am | What New Zealand dairy sheep farms are like | Greg Chambers New Zealand’s sheep-milking sector is young. This paper gives you a high-level overview of 20 commercial NZ farms (~50% of the industry) in the 2022–2023 season. In-person interviews with owners/managers captured information on farm scale, staffing, lambing and lamb management, milk harvesting, milking facilities/procedures, and animal health practices. We now have useful background information on NZ farms which vets can keep in mind when engaging with dairy sheep farmers, such as labour and resource challenges and constraints, common management practices, and where the biggest opportunities to help are. | Room 503 Level 5 |
| 12pm | Bulk milk SCC and APC on dairy sheep farms | Greg Chambers This is the first systematic description of bulk milk somatic cell count (SCC) and aerobic plate count (APC) on New Zealand dairy sheep farms. We now know what average bulk milk SCC and APC values are, their ranges, and how much they vary between farms. We also know the link between bulk milk SCC and APC. Finally, farm-level aspirational targets were set for SCC and APC. | Room 503 Level 5 |

| 1.30pm | The scoop on the poop | Cara Brosnahan Facial eczema remains a major livestock health issue, and this national study is clarifying how widespread the risk is. Over three seasons, up to 350 farms a year are providing samples to measure FE spore prevalence and identify key risk factors. Early results show spores consistently present from Otago to Northland, with clinical cases in both traditional and emerging regions. Spore levels often persisted into June, affecting protection strategies. This work is building a clearer national picture of FE risk, supporting better evidence based management for farmers and veterinarians, and generating data to develop a predictive risk model for the livestock sector. | Room 503 Level 5 |
| 2pm | Spore Wars: The Worm Front | Kristin Kirkpatrick and Cara Brosnahan Managing FE and internal parasites requires more than diagnostics, it requires system‑wide thinking. Using a real farm case study, this workshop explores how spore counts, faecal egg counts, pasture growth dynamics, forage choices, grazing management, and farm‑level risk indicators can be combined into practical action plans. Attendees will work through scenarios, strengthen their consultative approach, and practise turning on‑farm observations into clear recommendations. This session equips participants with practical, farm‑ready strategies to help farmers navigate FE seasons with confidence and build long‑term resilience into their systems. | Room 503 Level 5 |
