[QUOTE="Frankie, post: 687224, member: 13"] While I'd never argue that fertility isn't [b]the[/b] most important trait for a cow, that's not how we select our replacements. I've seen daughters of pathfinder cows that wouldn't settle. We've bought cows that didn't get bred to calve as a two year old, or didn't settle back after her first calf, and they've been solid, reliable producers for years. Management plays a big role in fertility. Because fertility is a low heritability trait, it's very difficult to use it as a selection tool. We keep it in mind, but select replacements/bulls based on other traits first. [/QUOTE]
