A diet delivery system for the controlled delivery of food to an animal particularly adapted to facilitate intake monitoring and maintain biocontainment capabilities while in microgravity is provided. The system includes a cage insert for an animal enclosure module having a diet servicing compartment adjacent an animal enclosing compartment. A diet housing unit is removably received in the diet receiving compartment and is held in place by a cover. The diet housing includes a housing aperture through which the animal feeds. A first barrier device is selectively movable to block the housing aperture or to allow feeding. A removable diet cassette is inserted in the diet housing and includes an aperture through which the animal feeds and a second barrier device selectively movable for blocking the cassette aperture or for allowing feeding. A diet container in which the food is stored is also provided together with a holding mechanism for releasably holding the diet container in the cassette.

A liquid supplement feeder having a covered tank, a rotatable wheel within the tank, and an opening in the cover over the wheel. A slidable plate is provided adjacent the opening in the cover and is adapted to partially close or completely close the opening so as to limit access to the wheel.

An improved poult box for transportation of newly hatched turkey poults. The box has an open top, a bottom joined by opposing sidewalls and at least one box divider. Positioned on the box divider is a removable poult feed tray which rests over the divider and presents feed at approximately eye level of turkey poults.

This invention is directed to a feeder construction and one which is especially adapted as a bird feeder wherein a novel and cooperative container and closure configuration is presented in such a manner that a highly efficient and practical feeder is produced. In the most preferred form, the container takes the shape of a hollow toroid having an interfitting closure in the form of an encircling ring slidable within a recessed channel in the outer surface of the container. Spaced openings in the closure are capable of orientation with a fill opening within the container upon rotational movement there between so as to provide fill access to the container. The lower interior portion of the toroidal shaped container is provided with a feed access opening for birds and the like. Furthermore, by varying the size of the central laterally extending recess within the container, various species of birds may be restricted from access to the feed opening.

This invention is a small animal feeder that physically restricts access to food by medium to large size animals. It is comprised of a 12 inch cube of cardboard with an extra elongated front forming a vertical 31/2 inch silt. A plastic feeder tray filled with food is inserted inside. It is the size and shape of the front opening that functions as both the barrier to medium to large size animals while allowing unlimited access to small animals. Currently used or patented pet feeders do not discriminate between medium to large size animals and smaller animals where access to dispensed food is concerned.
