VALENCIA-MAGANA, Favio et al. The goat udder: mechanism of milk secretion, and protein/fat synthesis. Abanico vet [online]. 2023, vol.13, e202.  Epub 27-Out-2023. ISSN 2448-6132.  https://doi.org/10.21929/abavet2023.10.

In recent years, the shift in milk marketing towards a standardized price structure based on dairy components has placed greater emphasis on lipid and protein concentration over the quantity of L or kg of milk produced. The nutritional content of goat's milk exceeds the nutritional content of cow's milk, in terms of proteins and fats, and it is the lactocytes of the caprine mammary gland, which must replicate and synthesize these components dairy products. Therefore, this review initially considers the understanding of the anatomy and histology of the mammary gland as responsible for all the activities related to the milk ejection mechanism. The development of the mammary gland determines all aspects of cell behavior, so its development is reviewed through four stages: i) mammogenesis, ii) lactogenesis, iii) galactopoiesis, and iv) involution. The remainder of the review emphasizes milk lipogenesis and proteogenesis, due to their various roles within cellular metabolism and the production of the lipid fraction and protein fraction of milk.

Palavras-chave : mammary gland; goat milk; lipogenesis; proteogenesis.
