In dream interpretation systems in Western Culture, there are no numbers assigned to various images perceived in dreams. That is not how dreams work. Instead, the roasted cow carcass (beef) can be understood as a symbol or metaphor referring to something in the dreamer's life. In this case, depending on how the individual dreamer feels about roast beef, it might represent abundant food or unexpected blessings.
The carcass of a cow lay in the road.
A beef carcass is a dead cow; a lamb carcass is a young sheep that is also dead. A dead young cow would be veal.

Hamburger is not from a designated area of the cow, it usually is the cutoffs from making the prime, select or choice cuts (such as steaks and roasts) and any left over meat from the carcass.
Menudo is another word for tripe, which is the stomach of a cow. The stomach is separated from the carcass, cleaned of all contents, scalded and bleached to clean it, then packaged and shipped out for consumption.
Usually the remaining meat on the carcass or any extra pieces taken when cutting steaks, roasts etc.
