Feed Efficiency and Its Impact on Feed Intake


Introduction

This fact sheet has been developed to support the implementation of the Natural Resources Conservation Service Feed Management 592 Practice Standard. The Feed Management 592 Practice Standard was adopted by NRCS in 2003 as another tool to assist with addressing resource concerns on livestock and poultry operations. Feed management can assist with reducing the import of nutrients to the farm and reduce the excretion of nutrients in manure.

When calculating feed efficiency, how do you account for variations in milk fat test?

When calculating feed efficiency, milk yield needs to be converted to 3.5% fat-corrected milk (FCM) yield.

The formula for correcting for milk fat is listed below for 3.5% fat corrected milk (which is the number I use).

Lb 3.5% FCM = (0.4324 x lb milk) + (16.216 x lb of milk fat)

Be sure to use pounds of milk fat (lb milk x % fat test = lb of milk fat in your herd).

For more information on calculating and …

Strategies to Improve Dairy Cows’ Feed Intake during Heat Stress

en Español: Estrategias para mejorar la ingestión durante periodos de estrés por calor.

Thermostasis is the process by which cows attempt to keep their body temperature constant in spite of changes in environmental temperatures. Heat stress occurs when the cow is incapable of dissipating enough heat to maintain its core body temperature below 101.3°F. This increase in body temperature results from the combination of heat from the environment and that produced internally during rumen fermentation and nutrient metabolism. In addition, …
