EPD'S

Now those of you that's bought a bull
Will no doubt agree with me
That the new fangled ways of pickin' bulls
Ain't what they used to be.

Now you need a geneticist
To help you do things right
Cause pickin' out a bull nowdays
Requires more than sight.

You have to know the dam and sire
And check out their pedegrees.
And then you have to reckon
With those things called EPDs.

Expected Progeny Differences
Are what those initials mean.
They help a rancher pick a bull
Without his calves being seen.

They deal with things like calving ease
And birth and weaning weights.
Not to mention scrotal size
And those maternal traits.

All these things together
Seem to help a racher know
Just what his calves will look like
And which bulls will have to go.

But one day I got to thinkin'
If they used such things on men;
And compiled all our data
And then put us in a pen.

I wonder just what changes
We'd have seen throughout the years.
And which ones of us would still be bulls
And which ones would just be steers.
