Abstract: A rice suspension cell according to an embodiment is useful for producing recombinant canine or feline albumin at high efficiency, and thus, by culturing the rice suspension cell, a large amount of recombinant canine or feline albumin can be safely produced at high efficiency. Moreover, it is expected that the veterinary composition for preventing, ameliorating, or treating hypoalbuminemia comprising the rice suspension cell of the present invention would greatly contribute to the resolving of the problems related to safety, social controversies, or the like that are caused by prescribing human serum albumin in veterinary care practice.
