Improving the environmental impact (NH3, P2O5) in broiler chicken farming

Reducing the use of protein and phosphate in feed of broiler chickens while meeting the requirements of the animals is desirable because this can reduce ammonia and phosphate emissions from animal husbandry. This strategy also saves globally limited resources. The project investigates concepts for reduced ammonia emissions in conventional and organic farming, as well as for reduced phosphate emissions in conventional fattening. The interdisciplinary consortium with 6 partner organisations investigates effects of protein and phosphorus feeding strategies comprehensively. This includes aspects of animal health and welfare. Methods for measuring emissions are also being further developed to enable more precise inferences.

In the sub-project at the University of Göttingen, feeding influences on the accretion of energy and nutrients are investigated, excretions of environmentally relevant substances are quantified, and consequences for product quality are derived. Together with emission measurements by project partners, proportions of excretions that become environmentally relevant emissions or remain as valuable fertilizer are quantified. The collected data can be used in the future to more precisely determine requirements of the animals for energy and nutrients. This would, again, help to conserve resources and reduce environmentally relevant emissions by feeding the animals closer to the requirements of the animals.
