Developing Replacement Heifers
Kaitlyn Sarlo Davila and Todd Thrift
Heifer development can be daunting: it is often one of the largest expenses of a cow-calf operation. This is due to feed costs, but also in large part due to loss when heifers don’t rebreed. For heifers, calving at two years old is the key to maximizing lifetime productivity. In order to calve at two years of age, heifers need to conceive at 15 months of age and reach puberty at 13-14 months of age.
