Why spend so much time on butchering?

I'm just curious to why there was a whole entire page dedicated to describing the hunters butchering the deer they killed? I am not used to this amount of description for minor parts of a story but it was just gross. I know that there's been a theme for a lot of description, like I understand that it may be necessary to describe the Green Knight because he's a pretty big deal in the story and its nice to get a good amount of imagery. Or to describe Gawain's shield since it shows his religious character, but why take so much time talking about butchering the deer they just killed? I feel that the main goal was to creep readers out or want them to know how to properly butcher a deer. I just did not feel the deer butchering scene help enhance the understanding of the plot, but I could've easily missed something that made it completely necessary to be so descriptive about it.
