having grown up around farms,

It's not roaming cattle...it's a mix of animals that contain cattle as in: -some cattle -some goats -some pigs -some chickens

Some solar farms already use goats in the USA to keep grass and weeds down...the group of animals together has some benefits as opposed to focusing on one group of animals alone....too long of an biology ecology lesson to put here...but you can go to your local land grant university ecology department and ask them to explain it to you as it is a fascinating subject and kissing cousin to why vertical farming never ever is sound from an investment money stand point.
