even though i do not have a particular
answer.
Some things i look at on my pigs is the amount of flab hanging around their neck. If it is tight to there neck. increase the amount of food by a bit. If it has 3 rolls, well ease up a bit.
Another thing i listen for is there grunts. is it just general " hey there you are let me grunt at you" or is it" please i am squealing give me some food" maybe increase it by a bit.
the real reason for my post was to ask for some photos of the pigs..... Please please long squeal please grunt grunt
