Colostrum for Dogs and Cats: Revisiting Its Biological Roles, Therapeutic Claims and Evidence-Based Applications

Prithwish Mukherjee

Abstract: Colostrum, the first secretion of the mammary gland following birth, is a bioactive and nutrient-dense fluid critical for neonatal survival. Rich in immunoglobulins, growth factors, and antimicrobial proteins, it facilitates passive immunity and supports intestinal maturation. While its role in new-born dogs and cats is well-established, colostrum is increasingly marketed as a nutraceutical for adult pets, with claims of immune enhancement, gastrointestinal support, and improved performance. This review examines colostrum?s composition, its proven benefits in neonates, and the scientific validity of supplementation in adult companion animals. Evidence confirms its indispensable role in neonatal immunity but highlights minimal support for systemic effects in adults. Processing and storage can reduce biological activity, and controlled studies in adult dogs and cats remain sparse. Further research is needed to establish effective and safe supplementation strategies.
