Swine Feed Processing and Manufacturing - Pork Information ...

All cereal grains fed to swine need to be processed to reduce the particle size by cracking, grinding, rolling, extruding, expanding, or other method before being mixed with other ingredients and fed as a complete diet. Processing improves the utilization of grain nutrients primarily through improved digestibility.

Study: Pet food particle size can affect digestibility ...

Reducing particle size of maize and sorghum nuggets can make them more easily digestible A recent study found that pet food particle size can affect digestibility. In the study, 54 beagles were fed maize, rice or sorghum in fine, medium or coarsely ground nuggets.

Enhancing feed utilization and nutrient digestibility ...

• Digestibility of wheat was influenced in 55 kg pigs by reducing particle size only from 700 to 500 microns irrespective of the grinding method used. In contrast, 110 kg pigs showed specific optimal particle size for best digestibility percentages (700 microns …

Roller versus hammer: Corn particle size impacts digestibility

Therefore, we conducted an experiment to determine the impact of reducing the particle size from 700 to 500 or 300 microns on digestibility of corn, and compared the outcomes when a hammer mill or a roller mill was used.

Reduction of Particle Size of Rhizoclonium riparium ...

The present study evaluated the effect of particle size (PS) of the Rhizoclonium protein concentrate on the apparent digestibility coefficients (ADC) as well as on growth and feed efficiency of the Pacific white shrimp (Penaeus vannamei) for 4 weeks.

Effects of brown rice particle size on energy and nutrient ...

However, the reducing particle size in brown rice had no effect on P balance, which was consistent with observations by Rojas and Stein who reported that a reduction in particle size did not affect the ATTD of P in corn. Thus, it indicates that the reduction in particle size of brown rice is not effective in improving P digestibility in pigs.
