Mob Grazing.

the oldest form of grazing.

Mob grazing is a method of rotational grazing
Instead of having 10 cows permanently in a 10-acre paddock, you might split the paddock into 10. With the ten cows spending three days in each one-acre paddock, you now have a system where each of the ten acres is being rested for thirty days. Taken even further, if you split the 10-acres into 30 x 0.3-acre paddocks, you could move the cows each day.

Simpler way of farming (less mobs to check, feed, move, etc.)
Biomimicry in action (mimicking the herds of bison being chased by predators)
With more cattle in a smaller area, they feed differently. Instead of spending time browsing for the sweetest of grass, they will eat a more balanced diet. Analogous to a diet of ice cream vs a balanced diet
With more cattle in a smaller area, the concentration of shit on the pasture is going to help fertilise the patch with less need for harrowing
If we are moving cows quicker than every twelve days, we are keeping them ahead of their parasites
If we are moving cattle quicker than the grass is growing back (~4 days), we are avoiding their eating of high nitrate, ice-cream grass
With more of the pasture getting longer rest times, the grass is able to grow a solid root reserve before being re-grazed, all the while putting nutrients into the soil through root exudates (plant pumps)
Rather than spending fuel travelling to different parts of the farm each day, there is only one or two places you need to be

Requires more electric fence gear to create strips within existing paddocks
Requires you to move cattle more regularly, ideally every day
Having less mobs will cause you to have cattle ready to sell all at once, creating a very infrequent income stream (with more mobs, you can better control when cows calve, when calves become ready, when the money comes in)
