“…A positive influence of LEO addition to the drinking water (0.5 mL/L) on the BW and FCR was obtained in the current experiment in the second (22–42 day) and the whole period (1–42 day) of LEO use ( Table 2 ). Yarmohammadi Barbarestani et al [ 5 ] obtained similar results in assessing the influence of LEO addition (main chemical ingredients: Linalool—38.12%; linalyl acetate—25.79%) to the feed at 600 mg/kg concentration. The study proved the efficacy of the influence on the chickens’ growth, mainly by an improvement of the intestinal microflora balance, intestine epithelium structure and antioxidant capability.…”

“…The results of studies that aimed to evaluate the influence of EO addition to the diet on the growth performance parameters of poultry are not unequivocal [ 4 , 5 , 16 , 17 , 18 , 19 ]. A positive influence of LEO addition to the drinking water (0.5 mL/L) on the BW and FCR was obtained in the current experiment in the second (22–42 day) and the whole period (1–42 day) of LEO use ( Table 2 ).…”

“…Contemporary broiler chickens are characterised by a gradually increased growth rate but are also more susceptible to different disorders and diseases, including but not limited to alimentary tract diseases, such as colibacteriosis [ 1 ]. Herbs deserve special attention because they have become more prevalent in feed mixes and supplementation preparations due to the content of valuable biologically active substances, e.g., essential oils (EOs) [ 2 , 3 , 4 , 5 , 6 , 7 ]. EOs are characterised by a multi-directional action [ 3 , 7 , 8 ].…”

“…Lavender essential oil ( Lavandula angustifolia —LEO) is among the EOs that deserve greater focus. It has antibacterial, antifungal, antioxidant and immunostimulating action [ 3 , 4 , 5 ]. The main LEO’s ingredients include linalool, linalool acetate, lavandulol and γ-terpinol, which reveal a broad scope of biological and pharmacological action [ 6 , 7 , 8 ].…”

“…The main LEO’s ingredients include linalool, linalool acetate, lavandulol and γ-terpinol, which reveal a broad scope of biological and pharmacological action [ 6 , 7 , 8 ]. On the one hand, LEO can be characterised by an activity that limits the development of pathogenic bacterial flora, and on the other hand, it can stimulate the growth of the beneficial microbiota [ 4 , 5 , 6 ]. Intensive farming means exposing broiler chickens to stress resulting from feed changing, transport and stocking density [ 9 , 10 ].…”

Biological activity of lavender essential oil is a property that can potentially find an application in poultry nutrition. Nowadays, the use of bioactive compounds is encouraged in many areas of industry and agriculture, since these substances have similar properties as withdrawn antibiotic growth promoters. Additionally, antibiotic resistance bacteria are one of the most important current threats to animal health. The purpose of the study was to determine the influence of lavender essential oil on the production parameters and blood parameters in broiler chickens and to assess the lavender oil’s in vitro reaction in a combination with enrofloxacin towards Escherichia coli. One-day-old non-sexed chicks (Ross 308) were divided into three experimental groups, each consisting of 100 individuals (five replicate of 20 boiler chicken each). The chickens in the control group received drinking water with no addition of lavender essential oil. In the experimental groups, lavender oil was added to the drinking water at a concentration of 0.4 mL/L, in the LEO1–42 from 1 to 42 days of age and the LEO22–42 group from the 22 to 42 days of age. The chickens’ body weight, feed consumption, water consumption, deaths and elimination due to health reasons were determined in the experiment. On day 42 of the chickens’ lives, blood samples were collected based on which selected parameters were identified. An in vitro experiment of lavender oil in combination with enrofloxacin was investigated with a checkerboard method. The results of the experiment showed the antimicrobial and antioxidant activity of lavender essential oil and its positive effect on the production results of broiler chickens. The study results proved that the addition of lavender oil positively impacted the chickens’ final body weight and feed conversion ratio (p < 0.01). No differences were observed between the groups for water consumption, death rate and the examined biochemical and immunological blood serum indices. Lavender essential oil was demonstrated to increase the blood serum’s total antioxidant status. A synergistic reaction in vitro was observed for lavender oil combined with enrofloxacin against resistant strains of Escherichia coli. Based on our study, a health-promoting effect of adding LEO to water for broiler chickens was found. Moreover, in vitro studies indicate a significant effect of lavender essential oil on the inhibition of the resistant strains of Escherichia coli growth and synergistic reaction with enrofloxacin.
