Forage Quality

The Forage and TMR Particle Separator was designed to help in determining the correct forage particle length needed to improve ruminant nutrition.

Discussion of factors affecting forage fiber digestion in dairy cows, including dry matter intake; the interaction of concentrates and other fiber sources in the ration with forage sources; processing and particle size of forages; and influences of fiber digestibility on performance and milk components.

Particle size evaluation tools are described and demonstrated in a series of brief videos.

There are several methods used to measure forage particle size. Each has a role in helping us understand the effects of particle size on the dairy cow. In this video Dr. Jud Heinrichs describes and demonstrates the use of the Penn State Particle Separator, which is a popular method for on-farm determination of particle size.

American Society of Agricultural and Biological Engineers (ASABE). There are several methods used to measure forage particle size. Each has a role in helping us understand the effects of particle size on the dairy cow. In this video Dr. Jud Heinrichs describes and demonstrates the use of the ASABE Particle Separator, which is the standard method for determination of particle size.

There are several methods used to measure forage particle size. Each has a role in helping us understand the effects of particle size on the dairy cow. In this video Dr. Jud Heinrichs describes and demonstrates the use of the Ro-Tap Particle Separator, which is the method originally used to develop the concept of physically effective fiber.

There are several methods used to measure forage particle size. Each has a role in helping us understand the effects of particle size on the dairy cow. In this video Dr. Jud Heinrichs describes and demonstrates the wet sieving technique used by Penn State researchers to determine the particle size of high-moisture samples, such as rumen digesta or feces.
