Concern was raised by animal welfare officers at the Animal Shelter last month after Paul Le Mière was granted an extension to keep some of his herd until they were older.
They said the young weeners were at a very vulnerable stage of their development and needed the best conditions possible.
Le Mière (58) was convicted three months ago of failing to provide adequate food, water and shelter for his pigs at Les Pallières Farm.
He was banned from keeping pigs and dogs for five years and fined.
The Assistant Magistrate, Ian Christmas, who heard the case, was told that the defendant fitted in his farming activities in breaks between working as a taxi driver.
The prosecution alleged he was ‘farming on the cheap’.
