Bulk milk urea concentration was evaluated to assess its potential as an indicator of ammonia emission from a dairy cow barn in a situation with restricted grazing. An experiment was carried out with a herd of, on average, 52 Holstein-Friesian dairy

Urinary urea concentration is an important predictor of NH 3 emission from dairy barns. To reduce urinary urea concentration, accurate and precise prediction of urea concentration for different feeding regimes is a prerequisite. The objective of this

To improve the slip resistance of solid floors in dairy cow houses and to achieve the ammonia emission reduction prescribed by the Dutch government, precast concrete floors with grooves and a dung scraper were investigated. The grooves parallel to th

Two methods to reduce the ammonia emission from double-sloped solid floors, with a gutter at the bottom of the flat “v” and baffles dipping into the slurry, in cow houses were investigated. The effect of two extra urine gutters in the sloping flo

In livestock buildings the ventilation rate influences both the pollutant emission rates and animal?s welfare. In the present study a 3D simulation model was used to simulate 7 commercial dairy cow houses with different roof types and side ventilator

The prevalence of clinical and subclinical digital disorders in 2121 pure breed and crossbreed Holstein Friesian and Dutch Friesian dairy cows, housed all year round in free stalls, was determined in a cross-sectional study on 34 farms (average herd

From July 2002until September 2003, a detailed ammonia emission inventory was carried out in concurrence with detailed measurements of the ammonia concentrations in air in a 3 × 3 km area in the East of the Netherlands. The main goal of the project

As the Dutch government and dairy farming sector have given priority to reducing ammonia emission, the effect of diet on the ammonia emission from dairy cow barns was studied. In addition, the usefulness of milk urea content as an indicator of emissi
