“…The highest nitrogen retention was found in T 3 -74.01±0.68 treatment group fed oregano oil with probiotic encapsulated Saccharomyces cerevisiae (200gm/ tones) followed by treatment group T 2 diet containing probiotic encapsulated Saccharomyces cerevisiae (200 gm/tones). These results are corroborating with Attia et al (2017) [3] who observed optimum improvement in the Nretention in broiler chickens fed a blend of plant extracts containing oregano, fenugreek, chamomile and fennel at different dietary 100 ppm and 200 ppm levels. The apparent total tract digestibility of dry matter, crude protein, and ether extract were increased due to the inclusion of the plant extract blend or antibiotic oxytetracycline (OTC) leading to improvement in N-retention.…”

“…In contrast to the present results Mathlouthi et al (2015) [17] in vitro antimicrobial activities of 3 essential oils [oregano, rosemary and a commercial blend of essential oils (BEO) against pathogenic bacteria Escherichia coli, reported a significant decrease in the bacterial concentration in the treatment. Total bacterial counts (coliforms particularly) in caecal contents were decreased for birds fed with a blend of plant extracts containing oregano, fenugreek, chamomile and fennel decreased Attia et al (2017) [3] . Du E et al (2015) [8] , Sarica et al (2009) [22] , Ilias et al (2016) [13] , Manafi et al (2018) [19] also reported similar results.…”

“…In the study of Attia et al. ( 2017 ), a total of 245 1‐day‐old chickens for fattening Cobb 500 (unsexed) were allocated to seven dietary treatments (35 birds/treatment), each including five pens with seven birds. The diets (starter 0–21, grower 22–35, finisher 36–42) were either not supplemented or supplemented with different treatments.…”

The specific concentrations of tetracycline, chlortetracycline, oxytetracycline and doxycycline in nontarget feed for food-producing animals, below which there would not be an effect on the emergence of, and/or selection for, resistance in bacteria relevant for human and animal health, as well as the specific antimicrobial concentrations in feed which have an effect in terms of growth promotion/increased yield were assessed by EFSA in collaboration with EMA. Details of the methodology used for this assessment, associated data gaps and uncertainties are presented in a separate document. To address antimicrobial resistance, the Feed Antimicrobial Resistance Selection Concentration (FARSC) model developed specifically for the assessment was applied. The FARSC for these four tetracyclines was estimated. To address growth promotion, data from scientific publications obtained from an extensive literature review were used. Levels in feed that showed to have an effect on growth promotion/increased yield were reported for tetracycline, chlortetracycline, oxytetracycline, whilst for doxycycline no suitable data for the assessment were available. Uncertainties and data gaps associated with the levels reported were addressed. It was recommended to perform further studies to supply more diverse and complete data related to the requirements for calculation of the FARSC for these antimicrobials.

“…Moreover, phytobiotics increase digestive enzyme activity, enhance feed conversion and hence improve the productive parameters of farm animals [ 17 , 19 ]. These improvements in digestive function have been related to the growth of beneficial bacteria in the cecum of broilers supplemented with phytobiotics, especially lactic acid bacteria such as lactobacilli and bifidobacteria [ 20 , 21 ]. These bacterial groups improve the host’s health by interacting with and training the immune system, allowing the host to allocate resources to production traits [ 22 , 23 ].…”

Phytobiotics (bioactive compounds extracted from plants) are one of the explored alternatives to antibiotics in poultry and livestock due to their antimicrobial activity and its positive effects on gut microbiota and productive properties. In this study, we supplemented a product based on garlic and onion compounds in the diet to laying hens at the beginning of their productive life (from 16 to 20 weeks post-hatching). The experimental group showed a significant increase in the number of eggs laid and in their size, produced in one month compared to the control. This increase in production was accompanied by microbiota changes in the ileum and cecum by means of high throughput sequencing analyses. These bacterial shifts in the ileum were mainly the result of compositional changes in the rare biosphere (unweighted UniFrac), while in the cecum, treatment affected both majority and minority bacterial groups (weighted and unweighted UniFrac). These changes in the microbiota suggest an improvement in food digestibility. The relative abundance of Lactococcus in the ileum and Lactobacillus in the cecum increased significantly in the experimental group. The relative abundance of these bacterial genera are known to have positive effects on the hosts. These results are very promising for the use of these compounds in poultry for short periods.
