we've got a round pen here, bought for the horses but realy handy for the cattle and sheep,

if you've got a shed just put the gate in the corner and tie it, you can push the cow then into the corner of the shed and pull the gate towards the wall to crush it

if you pull the tail up and to one side this will discourage it from trying to shoot back, or just go up behind it and hold it with your body pushed up against her back end, i'v done this to kickers and all sorts, we always use gates now, its alot easier

infact i've got some to tag tomorrow, i'll set the gate up and get some pikis if i get round to doing them
