Breeding mastitis out of the dairy herd

05.04.2004


New technology developed by CSIRO Livestock Industries (CLI) will lead to the development of new strategies designed to substantially reduce the $140 million lost each year due to Australian dairy cows contracting udder infections.




Developed with support from the Innovative Dairy Products Cooperative Research Centre (Dairy CRC), the bovine immune gene microarray provides researchers with the means to rapidly assess the gene activity profiles of infected and mastitis-resistant cattle.

"Mastitis is an infection of the mammary (udder) tissue caused by a range of bacteria," says CLI’s research team leader, Dr Ross Tellam.


"In dairy cattle this disease results in reduced milk production and altered milk quality and costs Australian dairy farmers between $120 and $150 per cow to treat.

"Identifying the genes responsible for resistance or susceptibility to mastitis opens up the possibility of selecting and breeding dairy cattle with an increased natural resistance to the disease," Dr Tellam says.

According to the Dairy CRC’s Chief Executive Officer, Dr Paul Donnelly, it is desirable that the industry develops approaches to managing mastitis which reduce the dependence on antibiotics.

"Reducing the incidence of mastitis through improved genetics will lessen costs to individual farmers and improve animal welfare," Dr Donnelly says.

The research is part of the Dairy CRC’s Gene Discovery Program which aims to identify, isolate and determine the function of specific dairy cow genes.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...
