Three men have been jailed for 20 to 41 years for having sex with horses, cows, goats, and dogs.

They have been sentenced to up to 41 years behind bars after they pleaded guilty to having sex with 9 horses, one cow, one goat, and several dogs.

Terry Wallace, 41, Mathew Brubaker, 31, and Marc Measnikoff,34, had sex with 12 animals in their makeshift farm, Clearfield County, Pennsylvania.

The three were arrested after a high school teenager, forced to restrain the animals, reported them to the police in Munson.

All three were sentenced from between 20 to 41 years in state prison, with additional probation.

The judge on the case, Paul E Cherry, described the crime as "one of the most disgusting, despicable courses of conduct I've ever seen."

According to the police, one of the men, Brubaker, admitted that he had sex with all-female horses in the firm, a cow, a goat, and his dog at least once every day for five years.

Measnikoff revealed that he had sex with the horses a couple of times every week, but he didn't have intercourse with the dog.

According to the police, the three men used to abuse the animals inside a holding pen, and after a police search, they discovered homemade videos, recording equipment, and cameras.

As indicated by Clearfield County District Attorney's, the horrifying acts were performed at a horse shelter they owned together. They later built a unique holding pen in the shape of a 'V' to encourage intercourse with the animals.

The men pleaded guilty to a misdemeanor of minors, 730 misdemeanor counts of intercourse with animals, and 730 summary counts of cruelty to animals. They also said sorry for their acts.

Chris Pentz, Wallace's lawyer, said during the trial:

"There is no question this case has an 'Ewww' factor."

Pentz also added that the defendants shouldn't be given such a harsh sentence arguing that they didn't' have any criminal records and the crimes they committed aren't against humans.

When Clearfield County District Attorney, William Shaw, watched the videos made by the three men, he said the clips had 'burned my corneas and will live with me the rest of my life.'

During the trio's arrests in August last year, Shaw said:

"This is an unpleasant topic, but the facts are that we received a report of folks having sexual intercourse with animals, farm animals."

"I've been doing this for over 20 years, and this is probably the worse situation of this type of case that I've come across."
