How do feedstuffs help in resource-friendly feeding of dairy cows?

The current discussion on more sustainable use of soil and groundwater requires the development of (more) environmentally kindly management concepts with a view to efficient nitrogen (N) and phosphorus (P) cycles. Accordingly nutrient-appropriate feeding systems must be created to feed dairy cattle, such as are already used to feed monogastric animals. Primarily the N-content and the P-content in the feed can then be reduced, their conversion rates structured more efficiently, and excretion into the environment can be reduced. Further reasons for taking swift action result from the recently adopted Fertiliser Regulation and the regulations governing agricultural construction measures.

Feed safety coupled with development flexibility

It is evident that living creatures are rarely totally healthy or totally ill, but instead deviate more or less distinctly from the ideal-typical condition. As a result of these fluid transitions, products to maintain or restore vital functions cannot always be clearly categorised as foods/feedstuffs or medicines. By way of improvisation, medicines are delimited in such a way that they are either intended by the distributing company to prevent, relieve or cure illnesses (medicinal products by presentation), or they contain clearly pharmacologically active substances (medicinal products by function).

16th International Symposium on Trace Elements in Man and Animals

The Symposium, which is held every three years, brings together some 250 scientists from 60 countries who carry out research into essential or toxic trace elements in human medicine/veterinary medicine, molecular biology/biochemistry, the environment, agriculture, and human and animal nutrition. The programme of the 16th Symposium from 26 to 29 June 2017 comprised 143 lectures and a similar number of posters. A brief overview of the Symposium contributions that are relevant for animal nutrition/veterinary medicine is given below.

The various metabolic processes, the work of the muscles and fermentation processes in the intestine generate heat in the body. If the body is no longer able to give off this temperature sufficiently to the surroundings, the body temperature rises. This is called heat stress.
