How did you get involved? Why did you get involved? And how's it gone regarding the ADOPT grant?

John WalshGUEST
Yeah, so we were introduced to EpiHerd and we thought the technology sounded fantastic.

John WalshGUEST
And the adopt grant allows you to fund a percentage of the work so that you can try novel technologies on farm and see if they work.

John WalshGUEST
So we went down the route and we applied... uh for the funding so that we could carry out the trial work on on on three of our farms so three of the vets in the practice actually have their own dairy farm so it's really it was a really good opportunity for us to try it and see if the technology is going to be you know is it going to be useful to our clients and uh to helen and myself we've both done um master's degrees in bovine reproduction and epigenetics was covered as part of that course and it's always fascinated me it's been one of the you know one of the things like you say Andrew that's just been mind-blowing and you think oh it's amazing that the daughters and daughters of those animals that are affecting that in for example in heat stress they've shown that the daughters of the animals that were heat-stressed when they were pregnant, they've produced much less milk, not just one generation, but the next generation as well.

John WalshGUEST
And if there's something we can do to investigate that, those things and put things in place to try and prevent it, then for us as a vet practice who try and take a proactive approach to animal health, we think it's a fantastic tool that we can use.

John WalshGUEST
The adopt process was, I mean, it's meant to be for farmers to to try on new things on their farms i mean i think possibly it's a it was a bit complicated for farmers to do but you do get help from a facilitator but even then i think it's Possibly quite, you know, I think the general farmer, I think, would struggle to apply for the ADOPT.

Andrew JonesHOST
What do you take? Are you taking hair samples? How are you then taking samples? So EpiHerd,
