We also sell heavy bred heifers in the fall to calf in spring. If your going to raise replacement heifers, you might as well take the time to breed them to a good, low birthweight bull, and sell as bred heifers. a "replacement" heifer could technically be any weaned heifer. The one's that develop a good reputation are the ones that cull hard and only keep the best to sell as bred heifers. Reputation is extremely important when selling bred replacements.
Last year our bred heifers sold around $950, my guess is this year's will be more like $1100. All were commercial brangus bred to a registered brangus bull. Around two years old at calving time.
