How dairy cows make milk

How dairy cows make milk

An animated resource showing the systems of organs and flows involved in the digestion and lactation of a dairy cow. A diagram of a cow is shown, with text underneath and animation to highlight the organs and illustrate the flows in the systems. The resource covers the cow’s four stomachs; the steps in its digestion processes; the function of the small intestine in sending nutrients from food into the bloodstream; the role of the secretory glands in the udder in converting nutrients in blood into milk; and the time it takes a dairy cow to produce 25 litres of milk.
