Overview

This course offers a foundational introduction to lactation biology, focusing on the anatomy, development, and function of the mammary gland. Students will explore the processes of milk production, secretion, and removal, and examine the nutritional composition of milk—including fats, proteins, lactose, vitamins, and minerals. The course also covers milk’s role in human health, including infant development and lactose intolerance, as well as the significance of bioactive milk components. In the final module, learners will gain insight into mammary health, identifying common conditions like mastitis and edema, and exploring prevention strategies. Designed for learners from diverse backgrounds, this course provides a comprehensive overview of milk science and its biological and nutritional importance. This course is part of the College of ACES suite of online programs, including the graduate certificate, "Dairy Nutrition for Udder Success" that can be stacked toward an advanced degree in the College of ACES.

Syllabus

Orientation & Module 1 | Introduction to Lactation Biology

In the course orientation, you'll get to know the course, your classmates, and our learning environment, and gain the technical skills needed. Then, start your journey into lactation science by exploring the anatomy of the mammary gland and the stages of its development. You'll also learn how milk is produced and removed through the processes of lactogenesis, secretion, and removal. By the end of this module, you'll have a solid understanding of how the mammary gland functions to support milk production.

Module 2 | What’s in My Milk? Composition and Labeling

Dive into the composition of milk and discover what makes it such a unique and nutritious food. You'll explore its major components—fats, proteins, lactose, vitamins, and minerals—and learn how different types of milk, such as organic, A2/A2, and rBST-free, compare. This module will help you explain the nutritional roles of milk’s key ingredients.

Module 3 | Milk in Human Health and Nutrition

This module focuses on milk’s role in human nutrition and how it’s represented on store shelves. You'll learn about lactose intolerance, the health benefits of bioactive milk components, and milk’s importance in infant development. By the end, you’ll be able to interpret milk labels and understand milk’s broader dietary significance.

Module 4 | Mammary Health and Disease Prevention & Conclusion

Explore the basics of mammary health, including common conditions that affect the udder. You'll learn to distinguish between mastitis and intramammary infections, recognize symptoms of mammary edema, and understand prevention strategies. This module lays the groundwork for identifying and managing udder health issues. At the conclusion of this module, you will be ready to complete the final assessment for the course and earn your Coursera certificate!
