| Adult flies are potential carriers of various microbiological pathogens due to their attraction to animal manure. The common house fly (Musca domestica) place their eggs on the surface of fresh manure and the hatched larvae undergoes three larval stages inside. Whether pathogenic microorganism from the manure may colonize the larva gut and ensure transmission to the adult fly is not known as larvae also nourishes on certain bacteria. In this study we monitored the effect of adding M. domestica fly larvae to poultry manure spiked with different test strains (E. coli, S. Enteritidis and C. jejuni), and followed the quantitative changes in manure, larvae and pupae as well as in the adult fly. |

| Introduction The common house fly, Musca domestica (Md) is an important carrier of zoonotic agents, and Campylobacter jejuni is one that may be transmitted between animals and humans by flies. Colonized animals shed the bacteria in feces where larval stages of Md flies develops. Aim of the present study To monitor fly larvae composting of poultry manure artificially contaminated with C. jejuni, and to investigate a possible transmission route of C. jejuni from the manure through the fly larvae to the adult fly. Conclusions The addition of fly larvae both accelerated the degradation of manure and C. jejuni. Pupae or newly hatched flies were not carriers of C. jejuni although larvae were grown in contaminated manure. Impact When composting poultry manure... |

| I foråret 2013 blev der gennemført et kombineret fodrings og infektionsforsøg med økologiske hønekyllinger på AU’s forsøgsfaciliteter i Foulum. Formålet med forsøget var at undersøge indflydelsen af fodring med fluelarvemel som alternativ proteinkilde til fiskemel på økologisk fjerkræ. Derudover skulle effekten af fodring med friske levende fluelarver på fuglenes tarmsundhed og adfærd undersøges. En eventuel probiotisk effekt af fluelarverne kunne ikke udelukkes, da fluelarverne var dyrket på frisk fjerkrægødning med henblik på at opnå kompostering. Derudover var formålet med forsøget at undersøge om fodring med friske fluelarver og larvemel påvirker forløbet af en Salmonella Enteritidis infektion hos kyllingerne. |

| In a feeding trial 450 layer chickens were fed either of 3 isoenergetic diets supplemented with different fish meal, grounded fly meal (Musca domestica) or fly meal and fresh fly larvae. The purpose of this study was to investigate the possibility of feeding grounded fly larva to layer chickens as an alternative protein source for fish meal in organic poultry. Parameters investigated were weight gain, food consumption, animal behavior and study whether it would have effect on intestinal health. |
