Quickly and accurately characterizing the nutrient content of feedstuffs is vital for balancing high-performance dairy cow rations. It also allows manufacturers to develop robust quality control programs and represent their products as precisely as possible. When it comes to supporting overall animal health and performance, one of the most important nutrients we evaluate as an industry is protein.

Assessing actual nutrient digestibility is key for balanced rations

Given this year’s uncertainties surrounding fertilizer, fuel and freight, one thing is certain – the feed bill will be going up. To prepare for a scenario where ingredients are expensive and potentially hard to come by, many producers and nutritionists are taking a hard look at rations and evaluating what can be removed.

As herd production levels increase, the importance of managing feed hygiene (the bacterial, yeast and toxin loads in feeds) also increases. High-producing cows have an increased demand on their system to support milk production and are more susceptible to blips in feed hygiene.

Feeding dairy cows is as much an art as it is a science, and there are several obstacles that can pose challenges to a successful feeding program. One of these challenges is the consistency of the feeds at our disposal.

The transition period is a key intersection of management on dairies. The sudden increase in demand for energy and nutrients to support milk production, coupled with the stresses of calving, contribute to many different metabolic disorders.
