Calving distribution is the percentage of calves born in each 21-day cycle throughout the calving season. Each time a cow is not bred during a 21-day heat cycle, it can cost up to 39 lbs of weaning weight (assuming an average daily gain on calves of 1.85 lbs/day).
The benefits of a shortened calving season are numerous:
Having more calves born in the first 21 days of the calving season allows producers to market larger, more uniform groups of calves and increase their profit potential.
It increases cow longevity.
Heifers that were born earlier have greater pregnancy rates, remain in the herd longer and produce one more calf in their lifetime compared to those that calve in later periods.
Herd vaccinations are easier to time.
Increased uniformity allows easier comparison between calves.

When life gets really stressful it can be hard to remember what you already know. This column probably won’t tell you anything new, but it might remind you of some important principles that can get overlooked in the scramble to buy feed and make important financial decisions.
Winter feed costs are a key financial make-or-break factor for cow-calf producers, especially this winter. Weaned calf sales bear most of the responsibility for offsetting those winter feed costs, so reproductive performance is another financial make-or-break factor. The most profitable cows are those that wean a calf every year for the greatest number of years.
The big challenge is that feed costs and reproductive performance are inseparable. Drastic measures to minimize per head feed costs usually have a negative impact on reproductive performance. Maximizing reproductive performance can increase feed costs significantly. But there can be some room to move in the middle. Maintaining or even improving reproductive performance can often be achieved by carefully managing the feed you have to maintain optimal body condition scores. This may mean spending money differently, not necessarily more of it, and will help maintain or improve reproductive performance. Continue reading →
Reproductive failure can pose a significant threat for cow-calf operations, particularly when an issue affects a large portion of the cow herd such as early pregnancy loss. This panel of veterinarians will share case studies of reproductive wrecks on beef operations and how these operations overcame and solved the problem.

A surprising proportion of producers believe they run a closed herd. The 2017 Western Canadian Cow-Calf Survey requested reasons why certain management practices were not employed on individual operations. Out of the approximately 25% of respondents who did not vaccinate their cows and heifers against reproductive diseases such as IBR and BVD, over half of those reported that their reason for forgoing those vaccinations was because they had a closed herd. Similarly, over 20% of respondents did not vaccinate their calves against respiratory disease (BRD), and 30% of those indicated having a closed herd was their main reason for not vaccinating.
This high rate of mistaken belief in having a closed herd is not just a Canadian phenomenon. A 2019 UK survey of almost 1000 producers indicated that over half of those who stated they ran a closed herd had purchased cattle within the past two years. According to the US Department of Agriculture’s National Animal Health Monitoring System (NAHMS) 2007-08 survey, over 88% of operations with 50 head or more brought new cattle onto their operations in the past three years.

I once spent a summer working for canola breeders. Some used traditional selection, while others were experimenting with transgenics. One traditionalist was known to say “sticking a new gene into a plant and expecting it to grow better is like throwing a new gear into a watch and expecting it to keep better time. It’ll probably get worse”. This article isn’t about canola or genetics, but it is about time and unintended consequences. Specifically, it’s about the timing of the breeding and calving seasons.
Canada’s cow-calf sector has moved towards fewer, larger beef cow herds. Calving later, on pasture has been a widely adopted strategy allowing producers to expand their cow herds without a proportional increase in equipment, labor, and facilities. When John Basarab led Alberta’s Cow-Calf Audits in the late 1980’s and late 90’s, breeding often started in May and calving started in late February. In contrast, 70% of the producers responding to the 2017 Western Canadian Cow-Calf Survey started breeding in June or July to calve in March or April.
Do you raise your own heifers? Or do you prefer to purchase your replacements? Regardless of your choice, developing heifers costs money and requires careful management.
Ideally, replacement heifers will go on to become long-term producers in the herd sothoughtful selection is critical. “Each producer has different resources and goals when they make the decision of whether they want to buy or retain heifers,” said Kathy Larson, a University of Saskatchewan economist. “Part of that decision needs to involve cost of production,” she advised during a recent BCRC webinar.
Sometimes it can be hard to know where you’re going if you don’t look at where you’ve been. For decades, research and extension organizations have promoted many practices to beef cattle operators with the goals of improving production, product safety, and ultimately profitability. Recently, the Beef Cattle Research Council (BCRC) and Canfax Research Services created a comprehensive report outlining the adoption of recommended beef management practices over time and across Canada.
The analysis used a broad lens to examine all cow-calf practices from feeding methods to manure management, calving cows to retaining heifers, pasture management to feed testing, and everything in between. Recent data from regional cow-calf surveys and research studies were compared to foundational producer survey and Statistics Canada information dating as far back as thirty-five years.
The first of its kind, this analysis:
Consolidated benchmarks for parameters such as conception rates, weaning weights, death loss, and calving season length;
Compared current practices and highlighted long-term trends across Canada where possible;
Identified gaps in adoption and potential extension opportunities;
As the breeding season approaches, some producers will consider using artificial insemination (AI) and estrous synchronization in their breeding herd; others will not because of the extra time, labour and management required in an AI program, the perceived costs of implementing AI, or they are unaware of the potential advantages of AI.
In this article, we will review economic analysis that compares the costs and benefits of fixed-time AI and natural service and discuss how recent changes in breeding bull and butcher bull prices affect the cost of breeding programs. We will also look at a recent study that addresses the question of how many clean-up bulls are needed in a fixed-time AI program.
Economic Benefits and Hurdles of Using Fixed-Time AI
Compared to natural service, an obvious potential advantage of fixed time AI is to have more calves born in the first 21 days of the calving season, which allows producers to market larger, more uniform groups of calves. Some studies have shown as much as a 10 to 17 day calf age advantage and 20 to 44 lbs more per calf at weaning as a result of estrous synchronization (Johnson and Chenoweth). Despite the extra costs of an AI program , fixed-time AI is estimated to have a net benefit of $11,110 for a 40-cow herd compared to natural service because of improved conception and wean rates, as well as heavier weaning weights (Lardner et al., 2015).

New resources have been added to www.BodyConditionScoring.ca to help cow-calf producers make decisions about managing body condition in their cow herd. Cattle producers know that fat cover plays a crucial role in the reproduction, health and welfare of their animals. These new resources will help guide them when modifying practices on farm to better manage body condition and increase their herds’ productivity and profitability.
The new feed cost calculator gives producers the opportunity to compare the extra expense of adding condition to thin cows in the Fall to the extra value gained by the resulting larger calf crop. The calculator is Continue reading →
