As john said, have options. Some animals also put more feed away than others. I have a heifer, she plows feed down as if it wasn't there. She can wolf 20lbs of haylage in about an hour, or less. She wolfs 3lbs of grain in 5 minutes or so, while others take their time. Then I have the heifers that take several hours to eat 20lbs of haylage, and 15 minutes or so for 3lbs of grain. The ones that eat heavy could eat some others as well, depending how you do it!
Also I have seen with mine, some grow faster than others. Some are at 55", while I have a couple at 52-53". Heck one about the same age is 2-3" different, due to her genetics (had the same feed, quantity). So that should be kept in mind, in some cases maybe it would be handy to know the sires, and dam's sires. IMO that would be helpfull as some sires tend to throw some fast growing calves, and some sires throw slower growing. I have a heifer (thea), her dam's sire was Ca-Lill. I talked to someone and mentioned thea's dam's sire. He said that he was a small bull. Thea's sire is Braedale Spy. There is another spy I have, and she is 2-3" taller than thea. She must have some of that bulls genes, that effected stature some. No biggy, she could milk heavier than the taller heifer anyways. I am not familiar with replacements, I would however know some backround info on each heifer, could be handy.. It isn't overly important, but what if a couple heifers seemed to be smaller, maybe you think "they aren't getting enough feed". Well what if the sire wasn't known for throwing big calves, and the eventual cows weren't super tall anyways. Just some thoughts. Because genetics do play a big role on a heifers size, feed yes, but aside from feed. I have a heifer, due in April. She will be 24 months in April. She weighs currently about 1200+lbs, another heifer due in June, who will be 24 months in April weighs 100lbs less. Same age, same feed, different genetics.
