Olive leaves provide half of the energy and amino acid requirements of sheep and goats at maintenance level and, if adequately supplemented, can be used as part of the forage in diets for production.
Olive by-products traditionally represent an important group of feed resources for ruminants in the Mediterranean areas. However, these materials are still under-exploited. Spanish and British Scientists have analyzed the inclusion of by-products from olive trees and olive oil extraction in the diets offered to goats and sheep.
Olive by-products were evaluated with respect to their composition, digestion, degradation, ruminal fermentation, and their impact on animal performance and on product quality, with particular attention to their fatty acid profile.
The study presents the effects on growth, milk and meat quality of feeding a range of olive by-products (olive leaves and cakes) to goats and sheep. In diets containing oleic acid the total monounsaturated fatty acid content of milk were increased, while saturated fatty acids dropped. Olive leaves provide half of the energy and amino acid requirements of sheep and goats at maintenance level and, if adequately supplemented, can be used as part of the forage in diets for production.

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
