Many producers have moved from spring to summer calving to avoid death loss from inclement early spring weather and to see a reduction in labor and winter feed costs. Just as there are upsides to changing timing of calving, there are also downsides, which may include reproductive challenges and decreased calf weaning weight. It is important to understand the change in management practices when converting to a summer calving herd.

Early weaning is typically defined as weaning before calves are 150 days of age. In extreme cases beef calves may be weaned at 45 days of age, but more commonly early weaned calves are over 90 days of age. Early weaning may be advantageous in times of drought, when cows are in a confinement system, or as a body condition management tool for very young or old cows. Once weaning has occurred, the cow, now without the demands of lactation, can be maintained on poor quality forage and little to no supplement.

Early pregnancy detection in replacement heifers or cows is a tool producers can use to increase profit. Traditionally, cows and replacement heifers are pregnancy tested in the fall of the year and then non-pregnant cows and cull cows are marketed at that time. This is also when cull cow prices are seasonally at their lowest.

Timing of Pregnancy Test

Pregnancy can be detected in cows as early as 30 days using ultrasound and blood tests.

Stocker-Yearling cattle can complement cow-calf operations by providing flexibility in utilizing grazing resources. In this month’s BeefWatch Producer Perspective Podcast, John Ravenscroft from Cherry County, Nebraska discusses how the Three Bar Cattle Company utilizes home raised and purchased calves to grow as stocker-yearlings to complement their cow-calf operation.
