Where does your magnesium come from?

Regularly test magnesium sources for solubility using simple methods like vinegar tests to ensure minerals are bioavailable, cost-effective and maximize the nutritional value in dairy rations.
December 9, 2025
Benjamin Wenner and Becca Culbertson

Low magnesium-containing mineral sources with high availability can still make a meaningful contribution to the magnesium status of your herd, and differences in solubility should be priced accordingly. Paying attention to solubility and payload ensures that every gram of mineral in the diet delivers value to the cow.

What do WWII combat analytics and dairy nutrition have in common?

Dairy nutritionists use linear programming for least-cost formulation, balancing nutrient requirements and ingredient values to optimize rations, reduce costs and maximize milk production based on evolving research.
October 10, 2025
Chad Jenkins

Given a set of nutrient requirements and a list of ingredients with known nutrient profiles and value, nutritionists may leverage linear programming to derive the most cost-effective combination of ingredients to supply these desired nutrients. This practice is often referred to as "least-cost formulation."

Rethinking chromium: From transition tool to full-lactation asset for dairy cows

Chromium supplementation improves intake, energy efficiency and resilience, with research and on-farm results showing benefits extend beyond fresh cows to support performance throughout lactation.
October 8, 2025
Rick Brown

Chromium has become a useful addition to transition diets. Supplementing with 6 to 8 milligrams per cow daily has been shown to significantly boost dry matter intake, energy efficiency and cow resilience. New data shows that these benefits go beyond fresh cows, supporting chromium supplementation throughout the entire lactation.

Grouping cows, cutting methane: The next step in precision feeding

New research shows how grouping cows by energy needs can lower emissions and improve efficiency.
October 3, 2025
Victor E. Cabrera and Chiung-Lun Huang

What goes into the bunk doesn’t just affect milk production, it also impacts the farm’s bottom line and its environmental footprint. Our team explored a simple but powerful strategy to address this challenge: nutritional grouping. The results showed promise.

Next-generation analytics for next-generation forages

Well-managed forage programs are a key aspect of any dairy operation, and tools such as MILK2024 are valuable metrics to help make decisions on both the quality and quantity of feed harvested.
January 3, 2025
Katie Raver

Well-managed forage programs are a key aspect of any dairy operation, and tools such as MILK2024 are valuable metrics to help make decisions on both the quality and quantity of feed harvested. As technology implementation increases, it is critical to assess what works for an operation and what doesn’t. Understanding the potential impact of these decisions on milk production can help producers do just that.

Challenges, opportunities and the future of AI in dairy nutrition

Thought leaders Chad Jenkins and John Goeser discuss challenges, potential and the outlook of AI in dairy nutrition.
November 1, 2024
Erica Louder

At the intersection of tradition and innovation lies the future of dairy farming, which is increasingly intertwined with artificial intelligence (AI) capabilities. AI has emerged as a transformative force as the industry responds to marketplace pressures and technological advancements. While integrating AI in dairy practices presents challenges, it also offers significant opportunities.

What do the new Nutrient Requirements of Dairy Cattle tell us?

Understanding rumen microbial function and nutrition has come a long way, and research continues to refine our ability to model and predict rumen fermentation outflow to support the cow’s needs.
May 29, 2024
Robert Van Saun

Feed costs account for more than 45% of production costs and approach nearly 60% with high feed costs. Obviously, dairy income is directly proportional to milk volume, composition and quality produced on the farm.

Assessing the value of protein feedstuffs for lactating dairy cows

AA Index can be used as an additional tool to compare different protein sources for lactating cow diets.
February 9, 2024
Logan Morris

Until recently, there was no great way to put a numeric value to the amino acid profile of feed. With the release of the 2021 dairy NASEM, we now have a method to determine the relative value of the amino acid profile of a given feedstuff.
