Tech advances boost milk output amid declining dairy farms

Large farms thrive with technology while smaller dairies struggle to keep pace

Milk production has been on the rise even as the number of dairy farms has decreased. According to a recent report from the Agriculture Department, this trend is due to technological advancements that have enabled larger farms to increase their efficiency and output, leaving smaller operations struggling to compete.

Between 2003 and 2023, annual milk production surged by 33%, reaching 226.4 billion pounds, based on the latest USDA data. During the same period, the number of dairy herds licensed to sell milk fell by 63%, with only 26,290 herds remaining.

Factors such as an aging workforce and higher production costs have contributed to this consolidation, alongside U.S. policies over the last decade that have boosted milk production and export market access, occasionally resulting in oversupply.

Large dairy farms, particularly those with over 1,000 cows, have managed to survive and grow by adopting advanced technologies and innovative management practices.

The number of these large farms increased by 60% from 2002 to 2022, whereas farms with smaller herds have significantly declined.

Smaller farms with fewer than 100 cows have faced the greatest challenges, with their numbers dropping by over 70% due to economic and operational pressures.

Looking ahead, experts like Peter Vitaliano, vice president of economic policy and market research, predict a continued decrease in the number of licensed dairies this year.

The decline in feed costs has improved milk margins, providing some relief to livestock producers compared to other commodity growers.

Despite the expected closures of more dairies, milk production in 2024 is forecasted to increase by over 500 million pounds compared to last year. This increase is driven by advancements in technology, genetics, and infrastructure, which help meet the high demand for dairy products like cheese, butter, and yogurt.

In response to FDA regulations, dairy farms are moving away from antibiotics and hormones and instead are leveraging modern technologies and techniques to enhance productivity. Examples include artificial insemination, automatic takeoff devices, and the use of nutritionists to design optimal feed rations. The use of computerized milking systems on dairy farms has doubled from 2000 to 2021.

Additionally, shifts in regional production have been noted, with states such as Idaho and Texas increasing their share of milk production, while California, the largest milk-producing state, has experienced a decrease in its share.

Analysis of greenhouse gas (GHG emissions) in the Canadian swine sector found that CH4 emissions from manure were the largest contributor to the overall emissions, followed by emissions from energy use and crop production.

This innovative project, "Improving Swine Manure-Digestate Management Practices Towards Carbon Neutrality With Net Zero Emission Concepts," from Dr. Rajinikanth Rajagopal, under Swine Cluster 4, seeks to develop strategies to mitigate greenhouse gas emissions.

While the management of manure can be very demanding and expensive for swine operations, it can also be viewed as an opportunity for GHG mitigation, as manure storage is an emission source built and managed by swine producers. Moreover, the majority of CH4 emissions from manure occur during a short period of time in the summer, which can potentially be mitigated with targeted intervention.

In tandem with understanding baseline emissions, Dr. Rajagopal's work focuses on evaluating emission mitigation options. Manure additives have the potential of reducing manure methane emissions. Additives can be deployed relatively quickly, enabling near-term emission reductions while biodigesters are being built. Furthermore, additives can be a long-term solution at farms where biogas is not feasible (e.g., when it’s too far from a central digester). Similarly, after biodigestion, additives can also be used to further reduce emissions from storage to minimize the carbon intensity of the bioenergy.
