Unsung heroes under the soil
Much of the scientific work being carried out at the Massey University led regenerative agriculture project, Whenua Haumanu, is below the ground.
It was organised by the Veterinary Bioscience Institute and LabRoots in the United States. Mellor says there is world-wide interest in the management and care of animals used in laboratories for testing procedures. The conference focused on looking at ways of minimising the invasiveness or impact of experiments on animals.
"For example if you are going to undertake a procedure that might cause pain, then you have an obligation to minimise that. You can't do that unless you can recognise the animal is in pain. Some very interesting work is being carried out on rats and even sheep on the use of facial expressions to indicate whether these animals are in pain."
Mellor is an expert in this area and says his paper was directed at widening the perception of what animals experience in a negative sense and what they can experience in a positive sense. He says by understanding this, researchers can do more to minimise negative impacts on animals.
New Zealand uses animals widely in research and this is well regulated by the National Animal Ethics Advisory Committee. But he says there is always a drive to do better.
"For example, in my paper I pointed out that whenever there is going to be a negative impact on an animal, there is a requirement to demonstrate that precautions and measures that have been taken keep that negative impact to an absolute minimum. What we can do better is keep on learning how animals perceive their world and how they experience it so we can better minimise negative impacts on them."
About 60 scientists from nine countries viewed his presentation. He based himself at Massey University in Palmerston North because of its high speed broadband. He simply logged onto a website and at an allotted time began his presentation.
"There was an opportunity for the participants to ask questions. They did this by typing their questions and it comes out on your desktop and you answer the question verbally."
The advantages of the virtual conference are time, cost and low carbon footprint. But he says he missed the informal interaction that occurs at normal conferences.
"But in a world of today this sort of conference will increase and organisers will find ways of setting up that 'between sessions interaction'."
