Phosphorus Metabolism During Transition
1Clinic for Ruminants and Herd Health, Justus-Liebig University, Frankfurter Strasse 104, Giessen, D-35392, Germany.
Abstract:
Phosphorus (P) in ruminant nutrition is under ongoing scrutiny because of concerns with P in animal waste polluting the environment. Laws aiming at containing the amount of P of animal origin leaching into surface waters are implemented in many parts of the world. Concerns with restricting the dietary P supply to high-producing animals do however persist. Overall, with the current pressure to be as restrictive as possible with the dietary P supply in high-producing dairy cows, a more in-depth understanding of the metabolic effects of P balance disorders in fresh cows is urgently needed.
