l   ? - r; from the "still" is called "thick distillery slop." This slop
.     is strained and the residue on the sieves is pressed and dried  A
  __* l . z by special machinery, the finished product being called "dis-
? e _ ‘ , tillers’ dried grains. " The fluid part going through the sieves
{ . E ~  is usually thrown away. '
Z ,  ‘ ‘    ‘ Before discussing the subject further, it would be well to
, _   _ review the different kinds of nutrients found in feed stuffs. -
Y   A nutrient is any constituent of a feed stuH that can yield,
~ -     when digested and assimilated, heat and energy, or can pro-
    ’ A ` duce bone, muscle, fat, hair, hoof, etc. There are four _
  `,,_ T .   classes of nutrients in feed stuffs, namely, protein, carbohy-
  __ it  A ‘_ drates, fat and ash. Protein is essential to the life of the p.
i gf f A cells of the animal and for the production of tissue, heat,energy
i ._     `_ l and fat. The fat found in the different feed stuffs may be
    , -   utilized by the animal body for the production of heat and
l `“,-   i ~ energy, or with little change may be deposited in the body as
  » fat. Ash is not only essential to the building-up of the
  `·,—     V bones of the body, but is present in varying proportions in `
  jj·_g_,“l ‘ , every tissue and fluid of the body. Chemists in their reports 1
  l usually divide the carbohydrates, which produce heat, energy ` _
    1 and fat, into nitrogen-free extract and crude fiber.
