10.30am: Passive transfer of antibodies to calves from dams vaccinated with Salvexin B | Alistair Kenyon & Amanda Kilby
A randomized controlled trial was carried out on a commercial dairy farm in Canterbury in 2019 to investigate S. Typhimurium colostral antibody transfer following vaccination with Salvexin+B at dry-off (PSC -75) or pre-calving (PSC -28). Vaccination conferred significantly more S. Typhimurium colostral antibodies to calves compared with leaving dams unvaccinated. There was no difference between the dry-off and pre-calving groups. The effect of vaccination was significant despite background seropositivity of S. Typhimurium in the study herd and a failure of passive transfer rate of 30%.

11.10am: Calf opportunities project | Ina Pinxterhuis
11.30am: Does the calf feed from its dam? | Emma Cuttance
12pm: Proactive calf rearing programmes | Mara Elton
1.30pm: Impact of a calf scours vaccine on colostral immunoglobulins| Greg Chambers
Calves are born without protective immunoglobulins provided by the cow in utero, so a sufficient volume of colostrum of adequate quality must be consumed within 6-12 hours of birth. We enrolled cows that were either vaccinated or not with a calf scours vaccine into a cohort study and showed that vaccinated cows had concentrations of particular immunoglobulin classes that were elevated beyond what was explained by increased concentrations of vaccine-specific immunoglobulins. The vaccine, in addition to its current indication for managing infectious calf diarrhoea, may also have potential for improving calf health through increased colostrum immunoglobulin concentrations.
1.50pm: BVD testing in calves - maternal Abs | Scott McDougall
2.10pm: Targeted selective treatment of R1 dairy heifers with anthelmintic: effects on performance | Andrew Bates
This study reports the results from a field trial looking at the effect of targeted selective anthelmintic treatment on dairy heifer weight at mating. Animals receiving fewer doses of anthelmintic had lower weights at mating. However, differences were small and there was no evidence for differences in worm burden or excretion of worm eggs. This suggests there are opportunities to reduce anthelmintic use and delay resistance but techniques to identify which animals to treat need to be perfected.
2.30pm: Drenching youngstock - testing for efficacy, egg reappearance periods, adequate refugia | Abi Chase
3pm: Hoof conditioning and exercise prior to calving in R2s | Winston Mason
4pm: Surviving clinical errors in practice | Brett Gartrell
4.30pm: Risk from a VPIS perspective | Steve Cranefield
4.50pm: Farmstrong - support for rural communities | TBC
5.10pm: GoodYarn in Practice – talking the talk and walking the walk | Emma Franklin
GoodYarn is an evidence-based, peer-delivered, mental health literacy programme for workplaces, both rural and urban, that enables people to talk about mental health. Anexa Veterinary Services was the first veterinary practice in New Zealand to attain a licence to deliver GoodYarn workshops to their staff. This presentation outlines the rollout of the GoodYarn programme at Anexa and how it has benefitted both their staff and clients.
Friday 19 November
8am: Ultrasound | Steve Cranefield
9.20am: Metricheck and metricure | Steve Cranefield
10.30am: Plenary | Sam Hazeldine
11.30am: Goat disbudding | Winston Mason
Disbudding is a necessary evil currently in the milking goat industry that results in a significant pain response during and after the disbudding process. This study investigates four methods of mitigating pain; a ring-block using local anaesthetic, a novel local anaethetic injector, a vapocoolant agent, and injectable general anaesthesia. Pain and stress responses were measured by movement and vocalisation during anaesthetic administration and disbudding, behavioural responses up to 24 hours post-disbudding, and serum cortisol concentrations.
