Session 1. High output dairy farming systems
Title Abstract Author Other files

The amount of maize in the feed ration influences milk composition in Northern Spain

The oceanic climate conditions of Asturias (Spain) are favourable for grass and pasture production. However, the use of concentrates in dairy-cow diets has increased in the last decades.

Production pasture versus exercise and recreation pasture for cows in automatic milking systems

In an automatic milking unit, a daytime grazing system with production pasture (group P) was compared with offering cows a small grass-covered paddock only for exercise and recreation, i.e.

Title Abstract Author Other files

Production potential of grassland and fodder crops in high-output systems in the Low Countries in north western Europe and how to deal with limiting factors

The farming community currently growing fodder crops and grassland in areas with intensive dairy production in the EU is confronted with opportunities and threats related to (1) characteristics of

Possibilities and constraints for grazing in high output dairy systems

In temperate and oceanic regions, grazed grass is the lowest cost feed available for milk production. In other regions, grazed grass is less important but can contribute to the diet of livestock.

Intercropping maize and Caucasian clover to reduce environmental impact of maize silage production

Maize (Zea mays L.) silage has become an increasingly important forage crop in high output dairy farming systems in Europe and North America because of its high energy density, relatively uniform n

Improved potassium fertiliser recommendation for grasslands in the Netherlands

Optimal potassium (K) fertilisation stimulates grassland production. In 2011 and 2012 fertiliser trials on grassland were executed to update the 40-year-old recommendations.

Undersown tall fescue as a cover crop after forage maize in 2014

Grass cover crops installed following the harvest of forage maize often develop poorly due to the late sowing date.

Yield comparison of Italian ryegrass and winter rye sown as cover crops after forage maize

Italian ryegrass (Lolium multiflorum L.) and winter rye (Secale cereale L.) sown as cover crops after forage maize, may produce an early cut before a new (maize) crop is installed.
