“…The progress in the feed additive industry and the production of encapsulated, heat-stable essential oils can protect them from oxidative damage and improve their overall quality (Attia et al 2017a). Digestibility and metabolic profiles reflect the responses of animals to feed additives (Khan et al 2012;Tufarelli et al 2016;Mokhtari et al 2018). In this context, we investigated the replacement of antibiotics by EOs as growth promoters in terms of growth performance and production efficiency index as well as biochemical, haematological and immune indices of broilers.…”

This study assessed the impacts of essential oils (EOs) consisting of 4.5 g cinnamaldehyde and 13.5 g thymol per 100 g of EOs as phytogenic growth promoters in broiler diet. A total of 216, one-day-old male Arbor Acres broiler chickens were randomly allotted into six groups, each with six replicates. The 1st group was fed a basal diet (Control) without supplementation; the 2nd group was fed the basal diet including zinc bacitracin (ZnB); the 3rd, 4th, 5th and 6th groups were fed the basal diet including EOs at 25 (EOs_25), 50 (EOs_50), 100 (EOs_100) and 150 (EOs_150) mg/kg diet, respectively. The group EOs_150 showed significantly increased (p < .05) body weight gain (BWG), enhanced feed conversion rate (FCR) and production efficiency index (PEI) compared to the other groups, except for EOs_100. Increasing concentrations of EOs above 25 mg/kg significantly (p < .05) increased protein, lipid and fibre digestibility; the addition of EOs also increased the amount of edible parts and dressing percentage of carcases. Diets EOs_100 and EOs_150 resulted in significantly increased plasma total protein and globulin levels, while EOs_150 led to higher plasma glucose concentrations. From the findings, supplementation with 100 mg/kg EOs in encapsulated, heat-stable forms could be used as an alternative growth promoter to ZnB in broiler chickens.HIGHLIGHT Essential oils can replace antibiotic in broiler nutrition with no adverse effects on growth performance. Essential oils improved total edible parts and dressing percentage. Essential oils enhanced digestibility of protein, lipid and fibre. Thus essential oils contained of 4.5 g cinnamaldehyde and 13.5 g thymol per 100 g can be used at 100 mg/kg feed as alternative growth promoter for broilers chickens.

“…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 ).…”

“…Küçükyilmaz et al [ 18 ] reported that EO feed with Lavandula stoechas (main chemical ingredients: Carvacrol—24.5%; 1.8-cineol—20.1%) had a negative impact on the BW, FI and FCR in the whole rearing period. Mokhtari et al in their studies [ 16 ] discovered that an addition of LEO (main chemical ingredients: Linalool—44.31%; linalyl acetate—32.98%) to the feed at 100–800 mg/kg did not affect the fattening production parameters, while a reduction in the breast muscle weight was observed for the supplementation dose of 400 mg/kg feed. The diversification of the test results can be related to the applied supplementation, concentration, form, and administration method (water, feed) and the EOs’ ingredients’ biological activity.…”

“…The diversification of the test results can be related to the applied supplementation, concentration, form, and administration method (water, feed) and the EOs’ ingredients’ biological activity.

“…The results correspond to the previous diet experiment [ 4 ] and the results obtained by Torki et al [ 17 ], who did not demonstrate LEO supplementation’s influence on the blood biochemical parameters in laying hens. Mokhari et al [ 16 ], who used 100, 200, 400, 600, and 800 LEO (mg/kg) as a feed additive, did not observe any differences in the total protein, and cholesterol, triglycerides, HDL, LDL or uric acid. They revealed a glucose concentration reduction in the groups of LEO-supplemented chickens compared to the control group.…”

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.

BackgroundVitamin D possesses an important role in the maintenance and health of broiler chickens. Herbal essential oils (EOs) have been proposed as a suitable alternative to chemical drugs in intensive production management systems for better performance of broilers with slight side effects and admirable therapeutic properties.ObjectivesThis experiment was conducted to investigate the effects of feeding cholecalciferol (VD) in combination of Satureja rechingeri EO (SREO) on growth performance, haematological indicators and immunological response of broilers.MethodsA total of 540 1‐day‐old mixed‐sex broiler chickens (Ross 308) were used in a completely randomized design with a 3 × 3 factorial arrangement of treatments. Experimental treatments included different concentrations of cholecalciferol (VD) (0, 2000 and 4000 IU/kg = 0, 0.05 and 0.1 mg/kg) and SREO (0, 200 and 400 mg/kg) on growth performance, haematological indicators and immunological responses of broiler chickens were investigated.ResultsThe results showed that the chicken fed diet supplemented with 0.1 mg/kg VD (VD0.1) in combination of 200 mg/kg SREO (SREO200) increased the feed intake during the overall and first 14‐day periods of the trial when compared with other dietary treatments. Interaction of VD0.1 × SREO200 led to more body weight gain (BWG) in the grower and finisher phases than all other feed treatment groups. The blood level of lymphocyte at day 42, heterophil at days 28 and 42 and heterophil/lymphocyte (H/L) ratio at 14 and 28 days of age were affected by VD0.1 + SREO200 in comparison with VD0 + SREO0 group. Feeding VD and/or SREO decreased triglyceride, cholesterol and low‐density lipoprotein concentrations at days 28 and 42 of the study, especially in VD0.1 + SREO200 treatment. Feeding VD0.1 + SREO200 also resulted in higher serum status of immunoglobulin M, lysozymes and phagocytic percentage among all treatments.ConclusionConsidering the outcomes, it is suggested that the combination of suitable concentration of VD and EO of the plant had favourable effects on the immune system and performance criteria of broiler chickens.
