Easy care sheep developed by AgResearch were produced using selective breeding. Find out more about selective breeding and why scientists use this method to breed the easy care traits. Rights: M ...
New Zealand sheep farming has been heavily influenced by fluctuations in demand and returns for meat and wool. Discover what other factors have contributed to this industry since the first sheep ...
To breed easy care sheep, scientists at AgResearch first had to find sheep that expressed the traits they wanted – they did this in stages. To manage the easy care sheep research efficiently and ...
Students use a three-level reading guide strategy to locate, interpret and apply the information to consider the role of research in finding easy care sheep traits. Purpose Students engage with ...
Students consider the harms and benefits (consequences) of easy care sheep breeding. Purpose Students use a round robin activity and PMI worksheets to generate ideas about the effect of selective ...
Cows are ruminants – mammals with specialised digestive systems that use fermentation processes to gain nutrients from plant material. Cattle, sheep, horses, deer, goats and camels are also ...
Earthworms are useful indicators of soil health. This project aims to capture information on earthworm abundance and species distribution throughout New Zealand. Information provided will be used ...
Weddell seals and orca are among the top predators in the Ross Sea region of Antarctica, and more than half of the Weddell seal population can be found in the Ross Sea. Information about changes ...
Antarctica’s crabeater seals are the focus of an international study led by the University of Canterbury. The aim is to understand potential environmental and social impacts on one of the ...
Students investigate silage production and test a stream to see if run-off from silage is polluting it. Students then produce a pamphlet of their findings to educate the community. Purpose To ...
Lincoln University has produced resources for year 11 students that focus on dairying in New Zealand. The purpose of the resources is to increase students’ understanding about the science and the ...
This case study was based on a biotechnology unit that focused on investigating silage and the possible effects of run-off on a small rural stream. This case study explores why this was an ...
Easy care sheep have been developed using selective breeding. Here, Dr David Scobie of AgResearch compares this traditional breeding method with the more modern cloning and genetic modification ...
Using peas, maths, and a lot of patience, Gregor Mendel uncovered some of the secrets of the gene. Nobel prize winner Sir Paul Nurse explains some of the monk's ground-breaking conclusions.
The heritability of a trait is determined by how much of it is inherited from the parents and how much is created by the environment. Dr David Scobie explains how heritable some traits are, some ...
This interactive shows the techniques used to make transgenic animals at AgResearch in New Zealand. Molecular biology techniques such as restriction enzyme digests, ligation, tissue culture and ...
This interactive shows how scientists confirm a newborn calf is a transgenic animal. View the steps AgResearch scientists use to produce a transgenic cow in this related interactive.
Ruminants like cows have an amazing digestive system. They are able to digest cellulose found in plant material – something humans cannot do. Drag and drop the text labels onto the boxes next to ...
