abstract = {Simple Summary: The growing interest in phytogenic products for use in feed, especially in the
poultry sector, is mainly due to the improvement in the productivity parameters and gut microbiota
modulation properties. For this reason, phytogenic products are becoming excellent candidates as
alternatives to the use of antibiotics in animal production to mitigate the negative effects derived from
their use. The aim of this study is to explore the ability of allium extract (containing garlic and onion),
used as an ingredient in laying hen feed, to improve performance. The promising results obtained in
the present study suggest that Allium spp. extracts had the potential to be used in feeding laying
hens to improve productivity, without affecting egg quality, and to modulate the gut microbiota.
Abstract: The use of allium extract containing propyl propane thiosulfonate (PTSO) as hen feed supplement
was evaluated to demonstrate its positive effect on egg production and intestinal microbiota
modulation. The study was carried out on 90 laying hens whose feed was supplemented with allium
extract for 28 days. Nutritional properties of eggs were not affected, whereas an improvement in
productivity was observed based on the increase weight of eggs. In addition, a modulator effect
on intestinal microbiota was confirmed by the increase in Lactobacillus spp. and Bifidobacterium
spp., as well as by the reduction in Enterobacteriaceae populations. Finally, the preservation of
egg composition was checked by monitoring the content of PTSO, using a new analytical method
consisting of the use of solid phase extraction and ultra-high-performance liquid chromatography
tandem mass spectrometry (UHPLC-MS/MS). Consequently, based on current results, Allium spp.
extract rich in organosulfur compounds such as PTSO added to the diet had a beneficial effect on the
microbiota and would seem to be a possible alternative to increase productivity, while not affecting
the biochemical composition of egg. However, further studies on the effects of allium extract as feed
supplement are necessary.},
