The strong trend towards more angular cows over the last decade is a consequence of the upgrading of the traditional British Friesian to Holstein.
Genetic selection in Irish dairy cattle over past decades has predominantly been on milk production. Genetic correlations with milk production suggest that, under such breeding objectives, animals will become taller and wider, and develop deeper, more strongly supported udders.
Research carried out at Teagasc Moorepark, in conjunction with the Irish Cattle Breeding Federation, suggests that animals are indeed getting taller.
“This has repercussions for optimal cubical and milking parlour design,” explains Dr Mairead Bermingham, Teagasc Moorepark. “In addition, animals also have developed deeper, more strongly supported and attached udders which has negative implications for udder health. Furthermore, animals have tended to become more docile and faster milking, which has both management and welfare benefits.”

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.
We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...
What enables electrons to be transferred swiftly, for example during photosynthesis? An interdisciplinary team of researchers has worked out the details of how...
For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
