Jordan Taylor, 22, from Basildon, had denied murder but was found guilty by a jury at Chelmsford crown court on Thursday and was sentenced on Friday.
He must serve a minimum of 23 years in prison for what the judge described as a "brutal crime", the court ruled.
Laura Davies, a 21-year-old horse groomer at the Essex Horse and Pony Protection Society base in Basildon, was attacked repeatedly with a knife moments after she ended her relationship with Taylor, the court heard.
The "frenzied" attack was so brutal that the knife used was left badly bent to a 45-degree angle.
