Creep feeding replacement heifers

I read on the Internet that creep feeding replacement heifers too early will decrease milk production by depositing fat cells in their udders can anyone clear this up for me and let me know when they start feeding

Creep feeding doesn't cause them to have reduced milk, it is the fat. If you are creep feeding a calf that is on a good milking cow, and they get too fat, then it will mess with udder development and cause reduced milk production as a mature cow. I spent an entire semester in a lactation course, it was truly interesting!
Moral of the story, I would adjust your creep based on the year, cow condition and calf growth. I would say for the most part, depending upon the operation/operator, creep feed is not a high return on investment. Then again, if its a dry year the cows could use the assistance. Again, this concept relies entirely on what your operations goals/objectives are.

I agree with BRB. I use a creep that is mostly oats. Some use straight oats. My creep consists of 1200#'s oats, 500# rolled corn, 75# molasses, and 225# 34.5% calf pellets. I would probably change that if i was just creep feeding steers.  I would also feed this based on cow BCS, pasture quality, etc. JMO

THank u so much it is a lot easier to understand in normal person talk

So when do you guys start feeding out your show heifers that you are also going to use as replacements

We start them from the time we wean right through the show season, changing it along the way to each calves individual needs. We have had some show heifers milk great after their show life and we have had some pretty average. i would say a lot of it depends on genetics but the feed will definitely change them. A good heifer ration along with genetics is the key to the heifers milk production.  We push as hard as we can trying not to get them fat but at the same time trying to get everything we can out of them.
