You cant got past a wee jersey cow for a pet, if you milk her later (after calving if you choose) then it will be real creamy milk and good quantities. Taming - depends on your time, be patient and let them trust you, feeding all the time builds the trust and a touch when you can that is gentle always helps with a good itch as they let you. Our calves love being rubbed under the neck/chin when they are used to touch, (I'll try and post a photo of Grunt our 1.5 week old - he was loving me all over last night
it was so awesome) to get them used to touch we just bottle feed them and then calfeteria feed them touching as often as we can. With older calves it is your constant getting close and touching. Just as per chooks. Feed them and they will tame.
1 acre per cow for grass, calves eat less. Watch out over winter for slower grass growth then need hay. Need hay or silage over summer if drought. Need HEAPS of water. Salt/mineral block for selp help access, we use wintering mixes with molasses in as well as other goodies, you could make you your own and put in colloidal silver if you wish. Also homeopathics are fantastic for cows.....just search or PM if you need help on that.
Hooves, havent needed to trim in 1.5 years of our dairy herd, other dry stock we have had over 6 years not needed hooves trimmed. Yay, horses trimming expensive and needed 4-5 weekly! ouch!
Hope this helps
