A few generations ago, my family were farmers, and I think I must have a 'farming gene' in my blood. The farmers I have met care passionately about their livestock. Along with our friends who own the smallholding, we spend time effort and money looking after the pigs, sheep and chickens... BUT ultimately they are for food.
The same goes for the occasional Roe deer, pheasant, duck etc.. that comes my way. I have no trouble butchering - and eating them.
In general, we never give the animals names. The exception is the registered pedigree ones and their names start with a 'year letter' - just like a car registration.
Pure breed Berkshire boars....
