It is intended that students acquire a comprehensive knowledge of the physiological, biochemical, cellular and molecular processes controlling the process of milk formation and secretion; develop an understanding of the anatomy and physiology of the mammary gland; to develop understanding of concepts relating to lactation physiology and lactation metabolism of farm animals; integrate physiological concepts and critically evaluate management issues related to lactation in farm animals: nutrition; milking management; control of metabolic diseases and mastitis control measures. Critically evaluate clinical and research papers related to lactation.
Mammary gland: Anatomy and Development
Neuro-Endocrine Control of the mammary gland: mammogenesis; lactogenesis; lactopoiesis; involution / drying.
The reflection mechanism of milk letdown.
Metabolic, Environmental and Nutritional aspects of Lactation. Prophylaxis of metabolic diseases associated with lactation.
Biosynthesis and secretion of milk. Precursors of milk and metabolic pathways.
Composition of colostrum and milk - biochemical and nutritional factors.
Milking: physiological factors and mechanical milking. The milking machine.
Mastitis and the Immune system of the mammary gland. Prophylactic control.
PRACTICAL CLASSES: Anatomy of the mammary gland; components of the milking machine; Hygiene of milking and control of mastitis.
The main methods of teaching are the explanation and exposition of the theoretical foundations of the previous syllabus of the course considering its multiple structuring elements, using the broadest possible range of teaching resources, including those offered by new communication technologies, information and research, to develop students' research skills, reasoning, imagination, sensitivity to the essence of the theme studied and critical and innovative formulation proposals for new solutions to some of the issues studied.
