“…The application of sub-therapeutic doses of growth-promoting antibiotics (GPAs) in the poultry industry has allowed the development rate and production yield of the birds to be increased while preventing infections [1] by changing their intestinal microbiota, metabolism, and intestinal function [2]. Feeding is a particularly important factor in commercial poultry farming as it represents approximately 70% of the total cost of production, which has led to increased use of GPAs in the poultry industry [3].…”

Background and Aim: The use of antibiotics as growth promoters in the feed of poultry, has contributed to an increase in the antimicrobial resistance of foodborne pathogens worldwide. Hence, the development of new effective alternatives to antibiotics that do not hinder productivity is imperative. For this, the aim of the present study was to determine whether oregano essential oil (OEO) extracted from Lippia origanoides is a suitable alternative to growth-promoting antibiotics (GPAs) for improving the performance, egg quality, and intestinal morphometry of ISA Brown laying hens. Materials and Methods: A total of ninety-six 70-week-old ISA Brown laying hens were randomly assigned to four treatment groups with four replicates per treatment and six hens per replicate. The treatments consisted of four different diets that were formulated according to the nutritional requirements of the genetic line and the production phase with and without the addition of GPA and OEO: NC, which did not contain OEO or GPA; GPA, which included 50 ppm zinc bacitracin as a GPA; 80OEO, which included 80 ppm OEO and no GPA; and 150OEO, which included 150 ppm OEO and no GPA. Results: All of the OEO and GPA treatment groups had a better feed conversion ratio than the NC group. However, the addition of 150 ppm OEO to the diet improved the percentage egg production and egg mass, as well as the external and internal quality of the egg compared with the other treatments. In addition, both the 80OEO and 150OEO treatments improved the yolk color, shell thickness, and shell color, as well as parameters related to the intestinal morphometry compared with the NC group. Conclusion: The findings of this study indicate that 150 ppm OEO can be used as a substitute for GPA to improve the performance, egg quality, and parameters related to the intestinal morphometry of ISA Brown laying hens.

“…Eggs have been shown to have high values of vitamins D and K, as well as increased concentrations of Se [3,16]. Researchers have indicated that this may be a reflection of the increased absorption of vitamins and minerals by hens in response to a change in feeding practices, with the replacement of feedstuffs of animal origin with vegetable oils [17] and other enhancements such as probiotics [18], prebiotics [19], enzymes [20], natural antioxidants [21], different botanicals [22][23][24][25][26][27][28] and the latest essential oils [24,[29][30][31]. Finally, eggs are well renowned for being the principal source of good and highly desirable dietary cholesterol, next to the cholesterol and certain fatty acids from fish [32,33].…”

“…Some useful and important effects of the phytoadditives in animal nutrition include the stimulation of appetite and feed consumption, increased digestive enzyme secretions, immune response activations and antioxidant actions [21,26,28,29,31], as well as the potential use in parasite treatments, such as Dermanyssus gallinae [49,50]. The tea tree (Melaleuca alternifolia) is an aromatic and medicinal plant, found in many parts of the world which is significantly used in agriculture and pharmacy [30].…”

The food of animal origin that is the most consumed is the table egg, but laying hens treated with antibiotics can produce eggs contaminated with antibiotic residues. Residues of antibiotics may present a risk for consumer health. Keeping in mind that laying hens almost always suffer from Mycoplasma (Mycoplasma synoviae), for which they are treated with antibiotics, high-quality egg production is even harder. Our research aimed to investigate the influence of three different antibiotics compared to the tea tree (Melaleuca alternifolia) essential oil administered to naturally infected laying hens with M. synoviae, on antibiotic residues in eggs as well as the egg nutritive and sensory qualities. A total of 20,000 laying hens, housed in one facility and divided into four lines each consisting of 5000 hens naturally infected with M. synoviae, was used. For the antimicrobial therapy, tetracycline (TC), oxytetracycline (OTC) and chlortetracycline (CTC) were used, respectively. As a control, tea tree essential oil (TT) was used. Based on the gained results all tetracyclines treatment residue values were significantly (p < 0.05) higher compared to the control treatment (TT), but without any significant differences (p > 0.05) between themselves. The results showed no differences in the nutritive and the sensory qualities of eggs between the control and the experimental treatments (p > 0.05). Keeping in mind the obtained results from this study, it can be concluded that tea tree essential oil could be successfully used as a natural antibiotic in the treatment of M. synoviae, without any adverse effects on table egg quality.

“…Similarly, bodyweight was not affected by supplementation with extracts of cinnamon, capsicum, oregano and thyme (Lippens et al, 2005). However, Popović et al (2016) observed increased bodyweight as a consequence of herbal supplementation. Likewise, no difference (P >0.05) that was attributable to the treatments was observed in the feed intake (Table 5).…”

Effects of Mentha piperita (peppermint) extract and juice on performance and immune parameters were evaluated in laying hens. A total of 252 Babcock laying hens were allocated to seven treatments with four replications of nine hens. The control hens were fed a basal diet without supplementation. Other hens were given diets supplemented with mentha extract (ME) at 50 (50ME), 100 (100ME), and 200 (200ME) mg/kg of feed or with 50 mentha juice (50MJ), 100 (100MJ) and 200 (200MJ) mg/L that was provided in the drinking water. No significant differences were detected among treatments in bodyweight, feed intake, egg mass, egg production, eggshell breaking strength, Haugh unit, and haematological and serological parameters. The ratio of gram feed to gram egg mass (feed conversion) was significantly better in the birds that received 100ME and 200ME compared with the control hens. The yolk colour index was higher in mid trial analysis (28th day). Thus, although the ME supplementation had a positive effect on feed conversion ratio and egg yolk colour at dosage rates up to 200 mg/kg, further research is needed to establish the efficacy of this herbal product and to determine the most appropriate amount to include in diets for laying hens.
