  • Processing Cereal Grains Fed to Dairy Cattle - eXtension

    Reducing the particle size of corn, sorghum, or barley increases the total tract digestibility of starch and thus increases the energy available from these feeds (Table 1). Steam flaking of cereal grains further increases their digestibility. The maturity of the grain, level of moisture, and the fermentation that occurs during ensiling results in higher digestibility of starch for high ...


  • Effect of dietary particle size and nutrient supply on ...

    Reducing particle size from 900 to 600 µm did not alter urinary or total N excretion (P > 0.10), reduced faecal N excretion 11%, increased total-tract digestibility of N and energy 3%, and increased ileal digestibility of N 9% and energy 11% (P < 0.05). Reducing particle size increased energy digestibility but did not reduce total N excretion.

    Like ground corn before it, the particle size of soybean meal and its effect on digestibility is gaining the attention of university researchers. A study reported in the Journal of Animal Science by Ohio State University nutritionist Don Mahan and graduate student Nathan Fastinger looked at the effects of reducing the particle size of soybean ...


  • Effect on amino acid digestibility of reducing the ...

    Research has shown that grinding cereal grains in diets fed to pigs into smaller particle sizes improves growth performance. Feed ground to smaller particle sizes has more surface area on which digestive enzymes can work, so digestibility of energy and nutrients that are enzymatically digested may also be …
