Three men have been arrested on a staggering 1,400 counts of bestiality after allegedly throwing orgies at their Pennsylvania farm.

Terry Wallace, 41, Matthew Brubaker, 32, and Marc Measnikoff, 34, were all arrested in Munson on Saturday after a 16-year-old boy who was living at the property reported them to police.

The teenager told authorities the men had been having sex with goats, horses, dogs and cows and that they were using a 'specially designed V-shaped pen' to do so.

The men were taken into custody and the teenager was placed into protective custody.

Police also found homemade video tapes and recording equipment on the farm.

Combined, the men were charged with 1,460 counts of sexual intercourse with animals but it remains how many animals were being held on the 'makeshift farm'.

It is not clear how many animals were on the property. There were 18 dogs alone.

They were also charged with endangering the welfare of children, corruption of minors and animal cruelty.

It remains unclear if there were more children living at the property.

Authorities do not believe the men sexually abused the adolescent boy but they say they are unsure of the extent of the emotional and psychological damage they inflicted on him.

The teenager also complained that the conditions were 'deplorable'. He said he was forced to collect rain water to shower and said there was no electricity or food.

The abused animals include several horses, 18 dogs, sheep, a goat and cows. Authorities are now trying to find new homes for them. Some of the horses are pictured at the farm after the men were arrested

Each of the three men were held in county jail on a $100,000 bond. They are expected to return to court on Wednesday.

On social media, Wallace and Measnikoff proudly shared photographs of the animals they look after and asked for donations from friends to support horse rescue charities.

Brubaker posed happily in pictures with a woman and group of children that are believed to be his family.

Authorities in Pennsylvania are now trying to find new homes for the animals. None were being starved but animal rights groups say the conditions were 'not ideal'.
