Mammals generally do not store significant amounts of carbohydrate, and post-mortem carbohydrate is metabolized from muscle and minor liver glycogen.

“because mammals generally don't store carbohydrate sure the carbohydrate that is found in muscle deteriorate sure is metabolized through rigor mortis after the animal is killed so all any available carbohydrate and muscle is gone the liver contains about three to four percent glycogen by way and it does remain after the animal dies but three to four percent of you know if you have a 200-pound deer doesn't amount to very many grams of carbohydrate at all it's practically none right”
