In one incident, Paul Le Mière (58), of Les Pallières, failed to notice two dead pigs in a dark barn which other members of the herd had started to eat.
The Magistrate’s Court banned him from keeping pigs and dogs for the next five years and fined him £1,600.
However, the five-year ban will be suspended for two months to allow him to dispose of his herd of more than 100 pigs.
The charges followed a visit of the farm by Animals Shelter inspectors on 5 November 2004.
One of the charges related to a dog which was left to sleep in an old basket which the prosecution said was littered with faeces.
Le Mière was convicted of failing to provide proper shelter for the dog.
The remaining charges related to his failure to provide adequate food, water or shelter for the pigs and piglets which were kept in outside pens or in a barn.
The court heard that Le Mière lived across the Island in Gorey and worked as a full-time taxi driver as well as keeping his pigs.
He also farmed land in other parishes.
Police legal adviser Bridget Shaw showed the court several photographs of the conditions in which the pigs were kept.
One showed that the mud and muck on the floor was so deep that it was at the same level as a basin water butt, which was also full to the brim of muck.
Other water containers were found to have animal faeces in them.
‘What all this comes down to, Mr Le Mière, is that you are farming on the cheap,’ she said.
She added that there were not enough hours in the day for the defendant to keep the animals properly given the rest of his commitments.
In his defence, Le Mière said that he tended the pigs daily.
The mortality rate among them was low, he said, and the animals themselves were healthy – something that vet Max Allan said that he had always found to be the case.
