PERCH SHAPE AND MATERIAL AFFECT PERCH USE AND HEALTH PARAMETERS OF LAYING HENS DURING THE REARING AND LAYING PHASE

Perch shape and material affect perch use and health parameters of laying hens during the rearing and laying phase

SUMMARY: Perches are an important resource for laying hens and differ in characteristics like shape, material and diameter.In this study, different perches were tested in regard to animal welfare, focusing specifically on the behavior and health of laying hens during rearing and lay.Five perches, i.e., square-fiber, mushroom-metal, mushroom-plastic

Species determination of Culicoides biting midges via peptide profiling using matrix-assisted laser desorption ionization mass spectrometry

Abstract Background Culicoides biting midges are vectors of bluetongue and Schmallenberg viruses that inflict large-scale disease epidemics in ruminant livestock in Europe.Methods based on morphological characteristics and sequencing of genetic markers are most commonly employed to differentiate Culicoides to species level.Proteomic methods, howeve
