Arbejdsområdet omfatter forskning indenfor den mikrobielle omsætning i foder og fordøjelseskanal hos enmavede husdyr (svin og fjerkræ) med speciel fokus på slagtekyllinger. Forskningen indebærer studier vedrørende sammensætning af den naturlige mikroflora i mave/tarmkanalen og de ernæringsrelaterede faktorer, som påvirker den mikrobielle udvikling og fermentering i fordøjelseskanalen. Målet med forskningsarbejdet er at finde egnede fodringskoncepter til slagtekyllinger for at styrke dyrenes mave/tarmsundhed uden brug af antibiotiske vækstfremmere. Alternative foderadditiva som gær og bakteriekulturer eller andre stoffer, som f.eks. enzymer, organiske syrer og specifikke kulhydrater, er af speciel interesse.

De anvendte analysemetoder omfatter anaerob dyrkning af bakterier, måling af den mikrobielle aktivitet i mave/tarmkanalen og kvantitativ analyse af de mikrobielle fermentationsprodukter i fordøjelseskanalen (kortkædede fedtsyrer (SCFA)og gas).

Research profile
Composition and activity of the natural intestinal microbiota in relation to dietary factors. Feeding and management strategies strengthening the natural microbiota and the gut associated immune function (fermented feed, probiotics, feeding enzymes, organic acids, specific carbohydrates and plant extracts). Focus on dietary factors that support gastro-intestinal health and suppress the abundance of zoonotic bacteria as well as bird pathogenic bacteria and parasites.
