Healthy, sustainable pig feeding through fiber-rich protein alternatives

Feeding of monogastric animals like pigs our poultry is in strong competition to human nutrition. The aim of the planned study is to establish sustainable and precise feeding strategies for pigs, to avoid nutrient wastes and optimise the genetic potential of the animal. Therefore a feeding trial with fattening pigs and three treatment (control diet low in crude protein and phosphor, diet with improved human edible feed conversion efficiency (HE-FCE) (increased content of regional industrial-by products) and a treatment where pigs can choice between both diets, should be conducted. Diets were calculated to reach similar available nutrient contents (energy, amino acids, macro and trace elements) between treatments. The trial will be split in a starter, grower and finisher phase (= standard in modern pig production). Diets of all phases reach the nutrient requirements of the Society of Nutrition Physiology (GfE 2006). During slaughter, samples of the intestine and blood plasma will be collected for further physiological and immunological relevant analysis (morphometry, blood count, microbiome, microbial metabolites). Analysis will be carried out the the Lab of the institute of animal nutrition, livestock products and nutrition physiology, as well as in the lab of co-operation partners.
