Abstract:
Properly mixing and distributing nutrients throughout a ration can be equally as important
as including them in the formulation. Many factors, including forage type, particle
length, and mixer type, affect the homogeneity of total mixed rations. Particle size plays
an important role in digestion and animal performance and, therefore, is an important
consideration from harvest through feeding. An increase in particle size results in a less
uniform distribution of nutrients throughout the total mixed ration. Typically, diets
with a high proportion of forages have the lowest uniformity of nutrients in individual
batches of complete feed.
