  • Is particle size important for swine diets

    Low moisture grain will shatter more creating more fines than normal moisture content of 1012 percent Increasing the flow rate of grain through the hammer mill will tend to increase particle size but it may result in more variation of particle size Roller mills have the advantage of creating a more uniform particle size than a hammer mill.
