    Abstract

    We aimed to study the variation in milk leptin around the time of parturition in dairy goats, and whether milk leptin can be absorbed and play a role in systemic regulation in the neonate. The results indicate that colostrogenesis in goats does not involve accumulation of leptin in colostrum, but secretion of leptin into milk increases and peaks within the first 2 days of lactation. This is likely the result of local regulation in the mammary gland in relation to lactogenesis. Our results did not suggest that milk leptin may play a role in systemic regulation in the neonatal goat.
