Hillsdown-- absolutely no idea.
She comes from my boss's dairy, and he runs herd bulls with the entire milking herd. No way of knowing even who her dam is. The heifer's sire is out of a 40,000lb cow named Ashley; came from the Parker dairy (no idea if you're familiar with them, but my vet tells me if he's at conferences and tells where he's from, the dairy folks often ask if he knows Blair, so I guess the fellow's sorta well known. :lol2
.
VanC -- the cow is spoiled rotten. Sure she's a 90lb cow when she's fresh, but were she on a dairy she'd have been culled a dozen times over the last few years. She's had footrot and mastitis. I nearly picked her off the dead animal pile and she has to have her hooves trimmed 1-3x/yr to stay sound. She's not pushed hard for production; in fact, she hasn't had grain in months. I watch over her like a hawk, especially around calving... good management is far better than good treatment. Sure she has genetics that enable her to stay in the herd easily (breeds back promptly, has a good udder structure) but she's a high maintanance animal and only with careful management and plenty of vet bills have I been able to keep her around this long. In her defense, most of it wasn't her fault, she was just unlucky.
I guess the best reason for her staying around this long is that she hasn't died yet and I refuse to cull her. LOL.
On the flip side, first year I had her, she finished out the year making a profit of $3K off calves she raised. When a cow makes that much money, you can afford to spoil her a little.
