Learning objects Dairy Australia: how do dairy cows make milk?

TLF ID M015285

This is 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 the food into the bloodstream; the role of the secretory glands in the udder in converting nutrients in the blood into milk; and the time it takes a dairy cow to produce 25 litres of milk.




Educational details

Educational value
  • This is a useful resource for the Biological sciences substrand of the science curriculum in years 8 and 9. Digestion, particularly rumination, in cattle is relevant to the content description in year 8 about multi-cellular organisms containing systems of organs that carry out specialised functions that enable them to survive and reproduce. Digestion, absorption and lactation in cows; is relevant to the year 9 content description about multi-cellular organisms relying on coordinated and interdependent internal systems to respond to changes to their environment. The particular value of the resource for these content descriptions lies in its straightforward explanations, clear diagrams and simple language.
  • The resource is also of considerable use in the Food and Fibre Production strand of the design and technologies curriculum from years 5 to 8, particularly for content descriptions that refer to investigating how and why food is produced in managed environments (5 to 6) and analysing how food is produced when designing managed environments (7 to 8).
