Re: mesh looking stuff inside a deer ??
This is what is commonly called caul fat in the culinary world. It is found in pigs, cows and sheep as well and is simply a thin fat membrane that covers the intestines. My guess is that not everyone notices it in their deer because deer are VERY lean to begin with and the membrane doesn't show much fat. It is probably only noticeable in deer with a very high fat diet. Chefs use this routinely to wrap meats and roasts. The fat melts when it cooks and seals the meat that it wraps and provides extra flavor and moisture.
