The Norwegian way to raising pigs is almost the same as we do in Madagascar, they just use a lot of machine. they catsrate the pigs when they get 2 or 3 weeks, the veterinary do it as the as student learn to do it in my school in Madagascar.
the pigs drinks water before to eat, and they put some water on the food but we never do thet in Madagascar because its more easy for the bacteria to live in the things wet especially "PROVANDE".
Norwegian teach the pigs to be clean. They put a metal wire in the middle of the pigs houses and they can play in stead of fighting each other.
when they separate the pigs with the mothers they put a lamp to warm them.
and they feed the pigs 2 or 3 times a day.
