It's Sunday so I am going to raise a ruckus. This was my first thought was something like this sermon from a preacher man.

If I am not mistaken the 3 in the triangle indicates that the loin is from a carcass with a yield grade of 3; that is, 53% or less lean yield.


In order to pass my meat-cutter apprenticeship I had to show that I could evaluate carcasses for sex, yield, and quality.

Also lets clarify the grades a bit.  Single A is for slight marbling not *cow* when someone says Cow you instantly think of an OTM (over thirty months) *cow* having calved every year for the past 6 years (lol) in order to fall into the A's ( A AA AAA) the animal must be youthful sometimes an animal can indeed be OTM but still fall into the A's.  IF however the animal has certain aging factors it then falls into the D's a *cow* would fall in the D's.  There being D1 D2 D3.  13 grades in total from Prime to E.
