Gestation calculations: A better management lever than ‘days carried calf’

Gestation length is variable. Understanding what it is and how to manage it will benefit your herd.
April 15, 2026
Peter Jackson

”Days carried calf” (DCC) is a familiar number – easy to filter and easy to build protocols around – but it can also be misleading. The issue is that DCC typically assumes a single fixed gestation length (often 280 days), while real-world gestation length shifts meaningfully with breed, parity, season/month, twinning, calf sex and sire genetics.

Why the placenta might hold the key to better breeding outcomes

Using new technology, researchers across the country are working to understand placental development and function in hopes of understanding pregnancy loss.
October 9, 2025
Kimberly M. Davenport

The placenta isn’t just a passive support system; it is an active, highly regulated organ that can make or break a pregnancy. The better we understand how it works, the better we can care for our cows and make smarter breeding decisions.

Reproductive road map: Leveraging data as your dairy’s GPS

Herd management software acts like a GPS for your dairy, delivering real-time data to guide reproductive decisions, boost efficiency and drive profitability.
May 9, 2025
Robert Heintz

Managing your reproduction program is complex, with many moving parts, but your herd management software can simplify the process. Just as a GPS helps you reach your destination without unnecessary detours, utilizing your herd management software to its fullest potential enables you to achieve your goals without costly missteps or delays.

What should reproductive management look like in robotic facilities?

Three experts weigh in on experiences they've had with clients managing reproduction protocols in robot facilities. Outlining goals and understanding cow behavior heavily influence success.
February 12, 2024
Matti McBride

“Change is easy. Transition is hard. Are you open to surrounding yourself with people who have the best knowledge and listening to them?” Nancy Charlton of DeLaval asked listeners of the “Capitalizing on robotics to enhance animal health and reproduction” panel at the 2023 Dairy Cattle Reproduction Council annual meeting.

Managing for the profitable cow

Productive isn’t always profitable. Use herd management data tools and insights to monitor cow performance, help keep costs in check and maintain a profitable herd.
January 25, 2024
Taliah Danzinger

A productive cow isn’t always a profitable cow. A profitable cow performs in milk volume and quality, breeds back quickly and experiences few health events.

Economic importance of cow longevity and depreciation

Cow longevity is directly related to the profitability of an operation. Cows that leave the herd before weaning a fifth calf saddle the remaining cows with extra costs.
April 17, 2023
Rick Machen

The verdict is in – an open cow is among the top three financial liabilities for cow-calf operators. Calf sales are the largest contributor to annual income; cows that fail to wean a calf are a financial burden borne by the productive cows.

When is the best time to get a cow pregnant?

The optimal time to get mature cows (lactation 3 and greater) pregnant is as early as possible but the results for first-lactation cows, and to a lesser extent second-lactation cows, has varied across herds due to the relative shapes of their lactation curves (i.e., their persistency).
February 20, 2023
Kevin Dhuyvetter

When thinking about lactation length and milk production, one aspect to consider is maximizing the returns to your most fixed resource on the farm. Is your most fixed resource the cow or the stall she occupies?

What every producer should know about calf growth

Before a calf is born, their growth potential is defined by the total number of muscle fibers that develop in utero. Maternal nutrient restrictions in early to midgestation can decrease the number of these muscle fibers.
October 3, 2022
Kalyn Waters

From gestation to the rail, there are things that will impact the calf’s success. Genetics, environment and management are among the biggest. However, before that calf is even born, their growth potential is defined by the total number of muscle fibers that develop in utero.

The value of reproduction

September 26, 2022
Rick Machen and Jason Sawyer

In cow-calf operations, reproductive rate is the foundational productive function of the enterprise. Obviously, if cows do not become pregnant, then no calves are produced for revenue generation the following year.

Using pregnancy testing for drought management

September 26, 2022
Gilda V. Bryant

Most beef producers who routinely test cows and heifers confirm pregnancies when their calves are either weaned or preconditioned in late summer. However, experts recommend checking for pregnancy much sooner, especially during a dry spell.
