GrazyDaiSy - Organic dairy cattle grazing on different sites in Baden-Württemberg: results and recommendations for action from a practical research project
First results about regionally adapted systems for pasture-based organic dairy farming.
The year 2018 was characterized by a pronounced drought combined with heat and pasture areas were not productive.
Solution
Pasture grazing is gaining in importance for organic dairy farms - even for farms that do not offer ideal conditions at first glance. For example, in very dry years like 2018, which was characterised by little precipitation during the grazing season combined with heat and the associated low forage yields. Studies have shown that these locations also have a potential that should not be underestimated, which is to be demonstrated with the help of this fact sheet.
Description
GrazyDaiSy is a European practice research project with eight partner countries. In Germany, it was carried out by the University of Hohenheim, as well as the organic associations Bioland and Demeter were carried out. The aim was to develop improved regionally adapted systems for pasture-based organic dairy farming. dairy farming. In the other countries, research was also conducted on the topics of animal health" and "cow-based calf rearing". calf rearing" research. This fact sheet provides an insight into the results of the first year of the trial. From July to mid September 2018, 27 organic and Demeter dairy farms in southeastern Baden-Württemberg were visited. By means of surveys, information was obtained on the farm structure, herd size and composition, as well as grazing and feeding management. were collected. These data were supplemented with information from the general farm documentation (e.g. FIONA or HIT data). In addition, the biomass and the forage value of the vegetation on the pastures was determined and sampled the forage offered in the barn, to assess the nutritional status of the animals and to estimate their feed intake and milk milk yield from the pasture. be able to.
