“…It was found that the use of different combinations of additives (such as medium-chain fatty acids, short-chain fatty acids, oregano essential oil, and sweet basil essential oil) exhibited positive effects on the growth performance of broilers [ 1 ]. Extracts of medicinal herbs (aromatic herbs) have received increasing attention from both researchers and producers as potential alternatives to conventional antibiotic growth promoters in broiler rations [ 2 ]. The beneficial effects of these essential oils as well as plant oils are related to their suitable chemical properties and functional groups, whose mechanisms of action remain to be explained [ 3 , 4 ].…”

The objective of this study was to investigate the effects of thyme and oregano essential oils (as growth promotors), individually and in combination, on the health, growth performance, and prevalence of muscle abnormalities in broiler chickens. Six hundred day-old Cobb 500 hybrid chickens were randomized into four dietary treatment groups with three replicates each. Chicks in the control group (C) received a basal diet, while the experimental treatment groups received basal diets containing 350 mg/kg of thyme oil (T1), 350 mg/kg of oregano oil (T2), and 350 mg/kg of thyme and oregano oil (T3). Growth performance parameters were evaluated at 14, 28, and 42 days. The broilers in treatments T1 and T2 had significantly higher body weights than the control group. The feed conversion ratio was the lowest in chicks who received oregano oil, followed by those fed thyme oil. The overall prevalence of growth-related breast muscle abnormalities (including white striping and white striping combined with wooden breast) in groups receiving essential oils (T1, T2, and T3) was significantly higher than in the control group (C). The thyme and oregano oil diets showed no significant differences in antibody titers against Newcastle disease or interferon-γ (INF-γ) serum levels. In conclusion, thyme and oregano oils had a positive impact on the growth performance of broiler chickens but increased the incidence of growth-related breast muscle abnormalities.

“…Biologically active components of essential oils of thyme, oregano, and rosemary stimulate the activity of beneficial bacteria, thus contributing to the balance of microflora, that is, they are an effective prerequisite for protection against pathogenic microorganisms (Abdel-Fattah et al, 2008;Puvača et al, 2022). Increasing the number of beneficial bacteria not only reduces the number of available substrates for pathogens, but also stabilises the pH of the intestine, ensuring optimal activity of pancreatic enzymes, which further leads to improved nutrient absorption and, accordingly, improved productive characteristics (Jakubowska & Karamucki, 2021;Puvača et al, 2022). There are also data on the anticoccidial activity of thyme and rosemary essential oils on the body of chickens (Lahlou et al, 2021).…”

The search for elements of technologies and preparations of natural origin that improve the functioning of the gastrointestinal tract of animals is relevant given that intensive growing technologies involve the use of a significant amount of various kinds of antibiotics that reduce immunity and negatively affect the quality of meat products. Preparations developed on the basis of biologically active substances from essential oils of medicinal and spicy-aromatic plants are promising in this area. The studies used the dietary supplement Activo, recommended for feeding poultry and pigs, created on the basis of essential oils of rosemary, oregano, and thyme. That is why the purpose of the study was to find out the effectiveness and safety of using dietary supplements as an element of intensive rabbit meat production. Research methods – zootechnical, laboratory, statistical. For intensive fattening of young rabbits of the newly created chinchilla type, a mixed feed recipe based on local feed ingredients was developed. It was established that with the addition of Activo to the diet of fattening young rabbits in the amount of 100, 150, and 200 g/t, their productivity at 90 days of age increased, in particular, live weight – by 2.4-5.3%, average daily growth – by 3.5-6.4%, lifetime loin width (meatiness index) by 2.0-2.4%, feed conversion improved by 4.1-5.6%. It is shown that the use of dietary supplements in the amount of 150-200 g/t of mixed feed in the diets of young rabbits with intensive production of rabbit meat reduces direct costs for the production of 1 tonne of rabbit meat by UAH 2,200 and increases the profitability of production by 5%. Thus, the use of a biological additive as an element of intensive fattening of young rabbits helps to improve the lifetime meat content and slaughter yield of young rabbits while reducing the cost of finished feed and increasing its conversion, which leads to a decrease in direct production costs

“…The most common type of terpenoids in EOs is monoterpenes, which can make up as much as 90% of the total and have a very soothing, subtle aroma. A monoterpene consists of two isoprene units, or 10 carbon atoms (Puvača et al 2022). Numerous terpene synthases monitor the synthesis of monoterpenes.…”

“…EOs from various plant species can include anywhere from 20 to 60 different biologically active compounds, with only a subset (20-70%) playing a significant role and the rest present only in minute quantities. It is possible for there to be a big difference in the amount of biologically active substances present depending on the plant parts utilized, the season they were collected, and the region they were cultivated (Hoffmann 2020;Puvača et al 2022).…”

New research has begun to develop safe and effective alternatives to feed-antibiotics as growth enhancers in response to mounting pressure on the poultry sector to do so. There is a significant demand for poultry products all across the world right now. To achieve this goal, key performance indicators are optimized, such as the rate of chicken growth, the amount of feed used, and the health of the flock as a whole. As a result of this growing need, various alternatives to antibiotics have entered the market. New approaches are desperately needed to keep poultry productivity and efficiency at a high level in the face of mounting pressure to limit the use of antibiotics. Recent years have seen an uptick in interest in the potential of aromatic plant extracts as growth and health boosters in poultry. The great majority of plants' positive effects are accounted for by essential oils (EOs) and other secondary metabolites. EOs have been proven to promote digestive secretion production, improve blood circulation, exert antioxidant qualities, reduce levels of dangerous microbes, and maybe improve the immune status of poultry. EOs are often believed to be safe, non-toxic alternatives because they are all-natural, chemical-free, and devoid of potentially harmful deposits. EOs are extracted from plants, and while there are thousands of them, only approximately 300 have been deemed to have significant commercial value. Many different types of bacteria, viruses, fungi, and parasites are negatively affected by EOs in multiple studies conducted both in vitro and in vivo. The review covers the fundamentals of EOs, their anti-oxidant and immunomodulatory capabilities, their growth-promoting benefits, and their effectiveness against numerous diseases in poultry.
