That was my big surprise in the Custer SP quote, that within an infected population, only 3 were actively spreading the disease.Yes, test and remove has been very successful in Hells Canyon. I've sat through a couple of presentations on the subject by Frances Cassirer recently. The really amazing thing to me was how few bighorns they had to remove overall.
NoDoes the disease affect their meat?
Do you think it is a wise move to release sheep that are actively shedding? Seems like that's the next step. A little more aggressive on the culling.
They used the test twice method in Hells Canyon with good success. Amazingly, they tested around 396 animals in 2013-2020 and removed 9. It really does seem like it's the chronic shedders that are driving disease in these populations with chronic low lamb recruitment. There is a larger subset of individuals that will only occasionally test positive, and removing those animals would probably face more scrutiny. Based on Francis Cassirer's results in Hells Canyon, it doesn't seem necessary.Do you think it is a wise move to release sheep that are actively shedding? Seems like that's the next step.

All animals that initially test positive by PCR will be recaptured the following year, then removed if still shedding. There are some mistakes in the article unfortunately. Early on in the disease outbreak phase, a higher percentage of animals will have active infections, so aggressive culling could be removing ewes that would otherwise recover. In herds where Movi has been circulated for many years or even decades, a “one strike” approach on older adults could be used if one didn’t want to be sure.Do you think it is a wise move to release sheep that are actively shedding?

Not sure if this belongs here or in the alpine happiness thread.

Thanks, but this article was a complete surprise to me when I opened my morning email from the Herald and saw a photo of myself.Great article @Oak
~ How many of the 1,650 are yours? And I know you're mentioned in a removal but how effective overall do you think the program is?
