Alan Blackman, 31, of no fixed address, admitted to trespass with the intent to commit a sexual offence and RAPE of a horse after a CCTV appeal was launched to track him down.
He was arrested after the animal was found injured and in need of veterinary treatment at farm stables in Redenhall, Norfolk, on August 6.
Blackman was sentenced at Norwich Crown Court as his wife, Sarah, 25, sat in the public gallery.
The court heard he had filmed himself abusing the horse. CCTV footage later showed him fetching containers to stand on in an attempt to have full sex with the animal.
Jailing him for 14 months, Judge Katharine Moore told Blackman: "You recorded this possibly because it was something you yourself might watch again or because it was something you might want others to watch. Unfortunately as a result of your actions, the horse sustained injuries."
Describing the offence as "somewhat unusual", prosecutor Claire Matthews said the horse's owner had become suspicious about a possible disturbance in the stable and checked security camera footage.
They found footage of Blackman sexually assaulting the horse.
Miss Matthews said: "In total he was in the stable for something in the order of an hour and 10 minutes."
She said Blackman was arrested after a police appeal for information accompanied by CCTV images was published in the media.
At first, Blackman went on the offense, insisting people were “putting my name to a face which isn’t me” and starting online speculation. He added that he would be “contacting the police to clear this up”.
When he spoke with officer, he initially told them he had been home with his wife at the time of the attack, which happened at about 10.15pm. But when questioned, Mrs Blackman confirmed he had not been home that night and did not return until the early hours.
Two weeks later, Blackman admitted what he had done to police, saying he was high on cocaine and amphetamine and CLAIMED could not remember the attack. He had also consumed large amounts of alcohol.
He also admitted he had previously viewed bestiality images but not "for his own sexual gratification".
After the attack, the horse was treated for internal injuries and it will need further surgery.
Michael Clare, mitigating, said Blackman is now unemployed and in debt.
"He has already sentenced himself to a lifetime of excruciating embarrassment," he added.
Blackman has since experienced suicidal thoughts, the court heard.
WIFE SAYS SHE STILL LOVES THE HORSE RAPIST
After he admitted the offence, his wife, Sarah, said she was "pretty disgusted" but that she still loves him adding: "I can't turn that off overnight."
She told The Sun she is not sure whether they will remain together.
Mrs Blackman said she wasn't sure why her husband had come to commit his vile crime, but revealed that in the recent months "things had changed."
"He just didn’t act like my husband," she said. “He was going out all the time and ignoring my texts and calls and lying about where he had been."
