As a follow-up to the first International Scientific Meeting on Colostrum held in Las Palmas, Gran Canaria in 2022, we are excited to announce the second meeting, which will take place in Guelph, Canada. We warmly invite you to join us and contribute to making this event a great success. Renowned speakers will present the latest research on colostrogenesis across multiple species, as well as new insights into the bioactivity of colostrum and its critical role in supporting neonatal calf health and development. This meeting offers a valuable opportunity to connect with scientists from around the world who are engaged in lactation biology, neonatal immunity, and maternal-neonatal interactions.
