What's New

Breeding Focus 2018 Reducing Heat Stress was held in Armidale on 19 & 20 September.

Topics presented at Breeding Focus 2018 Reducing Heat Stress, Breeding Focus 2016 Improving Welfare and Breeding Focus 2014 Improving Resilience were published into books which are available for purchase from AGBU. Abstracts of the papers for 2014, 2016 and 2018 are available as a pdfs and individual papers can also be downloaded.


Breeding Focus Workshop 2014

Improving Resilience

What is resilience in animal and aquaculture breeding? How does resilience differ from robustness, adaptation, tolerance, resistance or genotype by environment interactions in breeding applications? How does resilience of animals and of fish relate to productivity traits which have received most attention in breeding programs to date in all species?

Technology transfer relies on an active engagement of researchers with industry to enable a two-way exchange that keeps researchers up to date with current industry issues and informs industry stake holders of the latest research relevant for their business. The AGBU pig genetics workshops have been conducted since 1991 starting with an emphasis on the use of PIGBLUP, the genetic evaluation system used by most Australian pig breeding companies and then shifting towards specific research outcomes related to all aspects of pig genetics. This has been a unique opportunity for the pig industries to stay up-to-date with current genetic research. The challenges faced by individual breeding operations are similar across species, including livestock and aquaculture, and cross-fostering of ideas as well as sharing discussions between industries are beneficial and desirable. As a result, ‘Breeding Focus 2014’ was developed to extend this opportunity for exchange between industry and research to livestock and aquaculture species. Genetic improvement of resilience is the topic for Breeding Focus 2014. It is our aim in the future to address other topics of interest as an on-going series of Breeding Focus.

In animal breeding, disease resilience refers to the ability of an animal to maintain production at a given level of infection. It is noteworthy, that disease resilience in this definition is used synonymously with productivity. The concept of disease resilience can be further extended to a broader definition of resilience, e.g. environmental resilience. It generally characterises the ability of an animal to recover from any type of setback and return to an acceptable level of performance that optimises productivity and profitability for a wide range of challenging circumstances. Although the challenges faced by various species may differ between industries, the mechanisms and principles applied to breed animals with improved ability to bounce back from various challenges may be similar across species. As animal breeders, we benefit from exchanging ideas about pathways and approaches to breed for improved resilience. It is the aim of this workshop and book to discuss and outline industry experiences and strategies for genetic improvement of resilience of animals.
