Raising the steaks – the science of cattle breeding

This video explores the tools and techniques that are available to beef cattle producers to use in their quest to improve the productivity of their herds. It includes:

  • explanations of how and why estimated breeding values are used
  • description and footage of embryo transfer
  • advantages/disadvantages of artificial breeding techniques
  • interviews with producers and technical experts.

The main subject of the video is a particular cow (W449) who has produced 137 offspring over her life time.

Although it has been designed to support the content of the HSC Agriculture syllabus it is an excellent illustration of STEM.

Dairy farming into the future

This video documents the whole milking process in a robotic dairy. It presents footage of the robots milking the cows, the system of gates that control the flow of cattle into the dairy and the individualised automatic feeding process. Assoc. Professor Kendra Kerrisk (University of Sydney), describes the process and explains the reasons for its development and use.

The video shows an authentic application of robots currently being used in the Australian dairy industry.

Adam Kay – Cotton Australia

Adam Kay provided one of the keynote addresses at the STEM Action Schools Conference on 17 March 2016. In this address Adam describes how science, technology, engineering and mathematics has transformed the cotton industry.

Australia is the most efficient producer of cotton in the world. This efficiency is due to the genetic engineering of the cotton plant to be resistant to insect attack and herbicide tolerant, the developments in irrigation, harvesting and spray technology, yield management and soil moisture and nutrient monitoring.
