Claw complaints and lameness in dairy cattle are a considerable problem in livestock farming. Dutch research has shown that specific measures in the area of accommodation and management could improve the situation on dairy farms.
Joan Somers investigated the claw health of more than 7500 dairy cows on different stall floors. Four-fifths of the cows on a concrete stall floor, the most common accommodation, suffered from one or more claw problems. Cows in a straw yard had significantly healthier claws. A straw yard consists of a large bed of straw, often combined with a concrete corridor behind the feeding rack. Due to the drier and cushioning surface of straw, the cows’ feet in a straw yard are less susceptible to various claw disorders.
Somers also studied the effect of claw problems on the walking pattern of the cows on different floor systems. By far the best walking pattern was seen in cows in a straw yard. In more than 80 percent of cases, they walked normally. Less than 1 percent were lame. Cows on a concrete floor walked considerably less well. A quarter walked tenderly, whereas almost 30 percent of the animals exhibited some form of lameness. Only 45 percent walked normally in an unhindered manner. The poor walking was partly caused by painful feet as a consequence of claw disorders, but the hardness of the concrete floor was also a significant factor.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
