Resumen:
Most poultry
production issues are linked to a combination of factors related to management,
stress, nutrition and exposition to pathogens. Diet supplementation with
functional feed, products that provide a health benefit beyond basic nutrition,
may contribute to reducing some negative effects of captive breeding. Several
essential oils (EO) and their components have bioactivities on animal
physiology and metabolism including antioxidants, anticholesterolemics,
antimicrobials, and insecticidal, among other. The aim of this research was to
evaluate if the modification of quail diet, supplementing it with the EO
components thymol or isoeugenol, could have an effect on the production of
flies in poultry litter, a sanitary and economic poultry related issue. Manure
samples deposited in the previous 0 to 48 hs by quail that were fed with a
supplementation of 2000 mg thymol, isoeugenol per kg of feed or no supplement
(control) were collected. Each 200g sample (6 replicates per treatment) was
incubated in a container inside an emergence cage. Cages were inspected daily
and adult flies that emerged were collected for 40 days. The effect of quail
feed supplementation on the number of emerging flies, species composition and
emergence times were assessed. Significantly less fly emerged from manure from
the thymol treatment (P < 0.05) and a tendency to lower emergence was
observed from isoeugenol (P = 0.09). Significantly fewer Musca domestica emerged from thymol (P<0.01) or isoeugenol (P<0.01) manure than from the control. No
significant differences between treatments were detected in diversity indexes (P>0.05),
or development times of Musca
domestica
or the other frequent species Ophyra
aenescens and
Muscina stabulans (P = 0.40). Results suggest that the
modification of the quail diet with thymol or isoeugenol (at least at the
assessed concentration) may have a moderate effect against flies, leading to a
reduction in the number of Musca
domestica emerging.
