Management of Fresh Cows for Best Behavior
(2017-10-18)This presentation will describe the importance of understanding cow behavior in early lactation and how knowledge in this area of science can be used to evaluate nutritional management and housing strategies. -
Managing the Diet to Control Ruminal Fatty Acid-Microbial Interactions That Reduce Milk Fat Synthesis
(2020-10)In the early 1900’s, fat supplements were recognized for enhancing milk fat. A hundred years later, the opposite view prevailed causing major shifts in the types of fats fed to dairy cows to avoid a decline in milk fat. ... -
Meadow Fescue Grass Varieties for Optimal Forage Quality in Dairy Production Systems
(2021-10-19)Achieving optimal forage quality on dairy farms is key towards supporting high milk production. In New York State, over 85% of alfalfa sown is done in combination with a perennial grass, a unique practice in dairy production ... -

Milk Urea Nitrogen: Precision, Accuracy, and Individual Animal Variability
(2020-10)MUN can be a useful metric for managing diets and assessing environmental impacts but it is difficult to interpret without knowledge of the expected variability or measurement error. I will discuss results from some recent ... -
Modeling the Effect of Social Environment on Dry Matter Intake: Time Budget Behaviors and Stocking Density
(2020-10)This talk will cover the development of a mathematical model to account for management decisions on dry matter intake, milk production, and behavior of lactating cows. This preliminary model can be used for evaluation of ... -
Modeling the Nutrition-Environment Nexus: Completing the Cycle
(2018-10-16)Dairy farms are complex, interconnected systems. Nutrient management planning requires consideration of how the impacts of management decisions percolate through the entire system. Whole farm models can simulate interactions ... -
