- Collaboration and coordination of trials in the field of organic grassland and livestock farming

Studies on the avoidance of food-grade concentrated feed components in organic dairy cattle feeding (By-Product)

The efficient use of scarce resources is one of the major future issues in agriculture. This is especially true in organic dairy farming...

Investigation of flexible lying box systems for cattle husbandry (FlexBox)

Flexible cubicle partitions are an innovation designed to offer cows greater lying comfort. This project aims to investigate how...

1st Meeting of the practice group “Cow‑tethered calf rearing“

Cow-calf rearing is an innovative system in dairy farming. The EU project TransformDairyNet aims to develop practical systems for...

Sustainable food management through knowledge of agricultural animal husbandry

The profession of food manager often forms the link between agriculture and consumers. Therefore, a sound knowledge of... is of great importance.

Effects of short-grass or paddock grazing of dairy cows on individual animal and area performance

More milk with paddock or short-grass pasture? Each grazing system has its specific advantages and disadvantages. Paddock pastures are less suitable in dry conditions...

Species-rich pasture mixtures for the high-precipitation area in the Alps

Grazing is a central component of organic farming and is also included in the guidelines as a mandatory feeding system for...

Contribution of tiered grassland use to yield and biodiversity optimization on organic farms

Consumers who increasingly choose organic products also have a high sensitivity to...

Effects of short-grass or paddock grazing of dairy cows on individual animal and area performance

Pasture-based farming has gained importance in recent years; it is of central importance and essential in organic farming...
