No. The pigs in the movie are only a footnote; they belong to a deranged fellow who feeds them corpses that he collects from a nearby cemetery and other locations. The movie isn't about killer pigs, even though it was retitled and redistributed under the title "Pigs". It's really about a unhinged girl who spirals out of control and murders men that try to put the moves on her. Her trauma mainly due to her abusive childhood and incestuous upbringing with her father.
