County manager Derek Adams claimed Boyd handled before swivelling to fire in his first, and also argued that the Scotland striker had barged defender Brian McLean before heading in the equaliser in a 2-2 draw at Rugby Park.
He described the decision of referee Crawford Allan to let both goals stand as "a travesty" but Boyd said: "It is a man's game. They have big boys at the back and have to stand up to a shove and the battles that face you.
"It was a fantastic end to the game and we showed great courage and although it was a great point we are disappointed it wasn't three."
Killie boss Allan Johnston hailed Boyd's bravery, adding: "They were two great finishes from Kris Boyd who is a top-quality striker who puts his face in where it hurts. But we totally dominated the second half and really deserved at least a draw."
Both teams came into the contest intent on putting some distance between themselves and the Scottish Premiership relegation play-off spot, and the game was as keenly fought as any cup tie.
County, almost unrecognisable after seven January signings, looked certain to continue their transformation since December and were on course to make it four wins from their last six games after taking a first-half lead from French pair Yoann Arquin and Yann Songo'o.
Arquin finished off a swift move and inviting cross from Filip Kiss down the right wing on the hour mark, before Songo'o's flicked header from a Graham Carey shot made it 2-0 six minutes later.
Boyd halved the deficit two minutes into the second period and County's cause was not helped by the dismissal of Kiss. With 13 minutes left, the Ayrshire side grabbed the equaliser their pressure warranted, although the manner of it did not please Adams.
