While the idea of vibrating collars to steer cattle makes me uneasy (what comes next?), I am somewhat hopeful this can address the issue of barbed wire fences.
Interestingly, the idea of remotely controlling cattle was discussed several years ago in an article outlining the the issues with fences: https://prairieecologist.com/2015/03/17/hubbard-fellowship-b...
If a cow automatically moves to the right area then they don’t have to be herded. This reduces time. Some cows will likely need encouragement but it sounds like this reduces not only time, but stress on the livestock.
Fences are still likely needed.
It doesn't injure cattle. I have seen horses injured by barbed wire, but horses are sort of a special case.
* more flexible and appropriate sizing of grazing areas based on current herd size and where the grass is literally greenest
* the above can also increase dairy yield per sq/m by a considerable amount (I can’t recall the exact numbers I was quoted)
* multiple startups I’ve spoken to in this area also think they’ll be able to use on device biometric sensors to detect when cows need to urinate. Before that happens herd them to dedicated area or drainage pans. Again expected increases in yields and less pasture damage.
* biometrics also provide early indicators of potential health issues.
Nothing wrong with wire fences though. They’ve clearly worked fine for over a hundred years.
