For managing livestock you will need a few peices of modern technology to make things easier.
Lorex 720p camera system with enough coverage usually 6 night vision camera’s, wireless repeater and a wireless router.
Checking cows in the winter, here they usually go from a main holding/feeding pen into a pen behind the barn when they look ready. when you see them starting to show (butthole is sticking way out) or they are making lots of grunting put them into the barn pens to be monitored more closely. otherwise you’ll be pulling calfs to the barn while trying to make momma cow follow the calf there while you pull it on a sled(if its winter).
for handling cows i find bright orange gloves near their face helps move them in crowding tub. also if you need them to move ahead a soft tug on their fur and slight verbal aid can get them moving(pain seems to freeze them).
vibrating cattle prods might also help more than electric for keeping things calm.
If you get hogs take care of them with enough shade maybe a sprinkler they can trigger, mud pits are nice(they might have evolved from caves and bush where its cooler). train them to use the bite style waterers because the watering tubs are hard to keep clean even when fully drained and scrubbed. also electric fence will hold them so setup a large area for them to root through. they like leftover milk and chop mixed also most kinds of greens and garden varietys.
