I'm not sure how things are done there ,but here we run suckler herds ,
Can you get fresians there ,they are a hardy cow ,if it's covered by a beef breed ,then you can do what traditionally was done on holdings here ,take the calf off in the evening ,it can be done with care and makes for a nice handlable calf and leave it to suckle for the day,that way if there is a problem it can suckle instead of you milking ,then slaughter the calf when it's grown , traditionally here this was done with shetland cattle but most cattle over here such as dexter and welsh black were kept the same way
Something called strip grazing is getting popular here ,with not bad grass growth the gazing can make up most of the feed ,not sure if it's possible over there but used to work and still does in some places here
