Methods and compositions for producing selected non-human mammalian germ cells and gametes and for making non-human animals using the produced germ cells and gametes are provided by the present invention. Methods of generating a non-human embryo and/or animal derived from donor stem cells, methods of generating chimeric non-human animals having substantially all gametes and/or germ cells derived from the donor stem cells, methods of producing a non-human host embryo lacking functional endogenous germ cells and non-human host embryos incapable of developing endogenous gametes of the present invention are described herein.

The present invention provides novel methods of maintaining genetic stability of non-human animal inbred strains. In the methods, pedigree-tracked cryopreserved embryos or gametes or pre-gametes derived from a foundation colony are produced and used to re-establish the foundation colony at appropriate intervals.

摘要:
An animal ear tag that is sufficiently light and small that it may be secured to the ear of an animal without causing irritation to the animal or loss of attachment. The ear tag includes an identification code that may be in the form of human-readable or machine-readable indicia or an RFID tag mounted on or inside the ear tag. The ear tag may be part of a sequential set of ear tags arranged in a strip.
