Resumen:
ABSTRACT Many problems in poultry production are caused by a combination
of interrelated factors such as management, stress, nutrition and
exposure to pathogens. Saprophagous flies that develop in poultry manure
are a potential route of pathogen transmission. Besides their nuisance,
defecation and regurgitation of flies soils equipment and structures
and can reduce light levels of lighting fixtures. These effects clearly
affect management and may contribute to reductions in poultry egg
production, health and welfare. Many essential oils or their main
components have bioactive effects such as natural repellents and
insecticides, antioxidants, anticholesterolemics, and antimicrobials.
This study evaluates if supplementing quail feed with thymol or
isoeugenol as functional food could alter the production of flies from
their manure. Dropping samples deposited by quail fed with a
supplementation of 2000 mg thymol or isoeugenol per kg of feed or no
supplement (control) were collected. Each sample was incubated inside an
emergence cage that was inspected daily to collect emerging adult
flies. Significantly fewer flies emerged from droppings of quail fed a
thymol supplemented diet (P = 0.01) and tended to a lower emergence from
droppings of isoeugenol fed quail (P = 0.09). The number of positive
containers for Musca domestica L. was significantly smaller from quail
droppings of thymol (P = 0.02) or isoeugenol (P = 0.01) supplemented
feed than from their control counterparts, suggesting an oviposition
repellent effect. Supplementing quail feed with thymol or isoeugenol has
an overall moderate effect against flies, significantly reducing M.
domestica emergence.
