How Much Is Too Much?

[scout]

many trials have shown that if you select replacement heifers from the middle weight group your cows will tend to stay the same size when selecting the heavier weight hefiers you are naturally selecting for more growth and larger cows.

Sooooo...... larger cows equals more growth???

I didn't do the studies but my opinion is that when you select the larger heifer calves you are selecting the larger frame score females and over the generations the cows tend to get larger. just my educated opinion right or wrong.

Interesting responses.

Would it change your mind if I told you I had seen results that nearly duplicate these in Alberta, Montana, Colorado, South Dakota, and Argentina?

Is it so hard to believe that the average Angus and Hereford are now larger, and have similar mature size to Continentals?

I have noticed that bull selection has a direct correlation to mature cow size as well :wink:
