How the dairy farm industry contributes to sustainability

Sustainability has become a major talking point in agriculture. It’s a term you might hear in meetings, read in advertisements, or see referenced in industry discussions. But is it just a marketing buzzword, or does it truly reflect a movement toward sustainable agriculture? More importantly, what does sustainability mean for dairy farming and livestock production?

While it may seem like sustainability has always been a part of our conversations, the term only gained prominence in the 1970s. At its core, sustainability is about meeting the needs of today without compromising the ability of future generations to meet theirs. In agriculture, this means conserving resources, minimizing waste, and protecting ecosystems, all while ensuring consistent food production.

When applied to livestock, sustainability becomes even more complex. It’s not just about environmental stewardship; it involves balancing animal health and welfare, financial profitability, social responsibility, and food quality. These five sustainability pillars create a framework that dairy farmers can use to drive long-term success while caring for their animals, their communities and the planet.

Why sustainability matters in dairy farming

The world faces immense challenges in feeding a growing population. By 2050, the global population is expected to grow by 2.3 billion people, requiring 60% more food production. Livestock farm animals play a critical role in meeting these needs by providing high-quality, nutrient-dense foods such as meat, milk and other dairy products.

Dairy farms are integral to rural economies and communities, creating jobs and supporting livelihoods. In the United States alone, agriculture and related industries account for over 10% of jobs. Dairy farms contribute to this by providing employment and boosting local economies through processing plants, supply chains and more.

Sustainability also extends to food security, ensuring both the quality and quantity of food. By producing safe, nutritious milk and other products, dairy farms support healthy diets and meet the nutritional needs of a growing population.

How dairy farmers are contributing to sustainability

Sustainability doesn’t need to be an abstract concept; many dairy farmers are already implementing sustainable practices. These include:

• Using biodigesters to convert waste into energy.
• Recycling manure for bedding or as a natural fertilizer.
• Incorporating byproducts into cow diets to reduce food waste.
• Practicing responsible agricultural water management.
• Prioritizing animal welfare through improved housing and care.
• Adding dietary supplements to reduce cows’ environmental impact.
• Managing soil to maintain long-term fertility and productivity.

These actions not only enhance the environmental footprint of dairy farming but also improve financial profitability and community well-being.

The path forward for sustainable dairy farming

Sustainability isn’t just about the planet — it’s about people, animals, and the systems that connect them. As dairy farmers work to improve animal welfare, adopt new technologies and protect natural resources, they’re actively contributing to a sustainable future.

If you care about your animals, want a thriving operation, and believe in producing safe, nutritious milk, you’re already embracing sustainability. Every small step — from managing manure to conserving water — builds a better future for the dairy industry and the world.

Mejia Turcios is passionate about sharing his knowledge and research with industry leaders, producers, educators and other stakeholders in animal agriculture. Born and raised in Honduras, Mejia Turcios became involved in agriculture at an early age, with a particular love for livestock — which eventually became the focus of his studies. He earned a bachelor’s degree in agronomy from EARTH University in Costa Rica and a master’s degree in animal science from Texas Tech University.

Mejia Turcios completed his Ph.D. in June 2024 at the University of California, Davis, under the direction of Dr. Frank Mitloehner, an internationally known professor of animal agriculture who is also an air-quality expert and director of the CLEAR Center at UC Davis.

Jorge Delgado is an on-farm specialist at Alltech, where he focuses on empowering dairy workers for the benefit of the entire industry.

Originally from Ecuador, Delgado comes from a family of dairy farmers. Before joining Alltech, he offered consulting, sales and training services for an Ecuadoran genetic company and also served as a herd manager for multiple dairies in the United States. He has also worked with Elanco’s Dairy Training Program.

Delgado received a bachelor’s degree in agriculture and dairy science from EARTH University in Costa Rica. He and his family currently live in Minneapolis, Minnesota.
