Due to the demand from consumers, the antibiotic growth promoters are being replaced with alternatives in poultry diets, which include herbal growth promoters. The present study was undertaken to evaluate the effect of a phytogenic feed additive, PhytoGrow, on production performance parameters, egg quality traits, and gut microbiota in White Leghorn (WL) layer birds. A total of 540 WL layer birds, aged 42 weeks, were equally divided into 3
groups (180 birds/group); group 1 received PhytoGrow, group 2 received a probiotic product (Bacillus subtilis), group 3 received (Sodium butyric acid 30%), and PhytoGrow is a blend of potential herbs - Azadirachta indica, Curcuma longa, Andrographis paniculata, and Cinnamomum zeylanicum. The birds in all the 3 groups were raised on a standard layer diet and concurrently supplemented with the above additives at a mixing ratio of 500 g/ton and fed ad libitum for 12 weeks (42 to 53 weeks of age). Data on egg production, body weight, egg quality traits, and gut microbiota were assessed. The results of the present study revealed that there was no significant difference in performance parameters hen day egg production (HDEP), feed intake, feed intake/egg, feed conversion ratio, body weight, and egg weight) and egg quality parameters (egg density, egg strength, Haugh unit, eggshell weight, and eggshell defects) in WL layers fed different additives tested in the study. However, supplementation of PhytoGrow significantly reduced the count of Escherichia coli and Clostridium perfringens in ileum and cecum compared to those fed the other two additives. PhytoGrow supplementation significantly reduced pathogen count and numerically improved the performance and egg quality traits in WL layers during the mid egg production phase (42-53 weeks of age) compared to those fed probiotic and butyric acid in the diet.
