It is generally conceded, however, that good quality, heavyweight feed screenings, high in broken and shrunken wheat, wild buckwheat and oats, may be used to great advantage in some poultry mashes. When so used it is included in very restricted amounts, because of variation in quality and uncertainty as to the amount of dust, chaff, and weed seed present.
