Animal feeding-stuffs
This subclass only covers feeding-stuffs that are disclosed as being specially adapted, processed or formulated for non-human animals. Foods or foodstuffs that are of unspecified use or specially adapted for human beings are covered by other subclasses for foodstuffs (see the references below), for example the other subclasses of A23.
Production of animal feeding-stuffs
Processes for production of foods or foodstuffs that are of unspecified use, or specially adapted for human beings, are covered by the relevant subclasses therefor, see the references below.
Apparatus that is specially adapted for production of animal feeding-stuffs is covered by A23N 17/00.
Mechanical aspects that are of general utility are covered by other subclasses, see the references below.
Preservation of materials in order to produce animal feeding-stuffs
This subclass only covers processes for preservation that are specially adapted for production of animal feeding-stuffs. Preservation of foods or food-stuffs that are of unspecified use or specially adapted for human beings, are covered by the relevant subclasses therefor, for example A23B and A23L 3/00 (see the references below).
Mechanical aspects of processes for preservation of materials in order to produce animal feeding-stuffs are classified in other subclasses, for example A01F 25/00 and F26B (see the references below).
