hot dogs made with all beef and some pork lard.  that's the only pork product, is lard. for texture, since the cows are 

 they are coming in 1.4 to 1.5 lb packages now aug 2023 note.

ingredients - beef, pork FAT only (cause grass-fed beef is low in fat, and this needed texture) water, salt, paprika, sugar, spices, hydrolyzed corn protein, beet powder, dehydrated garlic and onion, natural spice extractives including paprika, modified potato starch, vinegar, nonfat dry milk, whey. 

to be clear - these are the old dairy cows sent off to be turned into hot dogs. you get tenderloin, and rump, and everything off the cow.  it is not one specific cut :)
