“…Oregano is a dietary additive commonly used in various animal production systems [ 37 ] due to its known antimicrobial effect and the resulting improved health and performance of growing animals. It is assumed that its chemical properties enable modulations of the gut microbiome and the immune system in piglets [ 38 ].…”

One of the primary substances responsible for the unpleasant odor in boar meat is skatole. Enzymes belonging to the cytochrome P450 (CYP) family play a pivotal role in the hepatic clearance of skatole. This study aimed to investigate the impact of oregano essential oil (OEO), Schisandra chinensis extract (SC), and garlic essential oil (GEO) on hepatic CYP2E1 and CYP2A activity in pigs. In three consecutive trials, cannulated castrated male pigs were provided with a diet containing 0.2–0.3% of one of these plant extracts. Following a 14-day feeding period, the animals were slaughtered, and liver and fat samples were collected. The findings indicate that the activities of CYP2E1 were unaffected by any treatment. However, GEO treatment demonstrated a significant reduction in CYP2A activity (p < 0.05). Pigs treated with GEO also exhibited a notable increase in skatole concentrations in both plasma and adipose tissue. In contrast, animals fed SC displayed elevated skatole concentrations in plasma but not in fat tissue. OEO did not influence skatole concentrations in either blood or fat. Furthermore, the study revealed that a supplementation of 6 g GEO per animal per day induced a significant increase in skatole concentrations in blood plasma within 24 h.

“…The different species of oregano are one of the most studied herbs used for their antimicrobial activity-antibacterial, antifungal, and antiviral. Among the activities and applications of oregano essential oil reported in the livestock industry and meat production are antioxidant, preservative, antimicrobial, and anticoccidial effects, as well as improving the production of digestive enzymes, stimulating digestion and blood circulation, and improving immune status [68][69][70]. The improvement of feed utilization efficiency and animal rearing performance could be determined by changes in intestinal morphology, such as the increase in the height of intestinal villi or the intensification of enzyme activity, with the improvement of protein digestibility due to the intervention of chymotrypsin and by the prevention of parasitosis [70][71][72].…”

Despite the continuous improvement of feed diets and recipes, animal health problems persist. For their treatment, antibiotics and chemotherapy have been shown to have side effects hard to control. The antibiotic residues in animal products may endanger human health. Since the antibiotics were restricted in animals’ diets, which were previously used to keep under control digestive and respiratory pathologies, as well as allergies, so the researchers began to search for natural alternatives. Thus, it was developed the concept of phytoadditives, and these natural plant extracts are gaining ground in animal farming. Since then, more and more animal breeders and farms are willing to use various types of phytoadditives. This chapter aims to present the most widely used phytochemicals in animal nutrition, their effects on animal production and health, and to make some recommendations on the use of phytochemicals in farm animals’ diets.

“…Oregano is one of the best-known aromatic herbs with significant commercial value, cultivated in many countries [ 21 ] and thoroughly utilized in the food and pharmaceutical industry [ 22 , 23 ], and its biomass propagation under controlled laboratory conditions has been described [ 24 , 25 , 26 , 27 ]. It is commonly used in human [ 28 , 29 ] and animal [ 30 , 31 ] diets as a spice, a source of antioxidant compounds, or as an anti-microbial agent for the in vivo inhibition of foodborne pathogens [ 32 , 33 ]. Different parts of the plant, either fresh or dry, display strong antioxidant properties attributed to a multitude of metabolites such as phenolic compounds, flavonoids [ 34 ], phenolic glucosides, resins, sterols, tannins, and triterpenes [ 22 , 35 ].…”

Oregano (Origanum vulgare, Lamiaceae plant family) is a well-known aromatic herb with great commercial value, thoroughly utilized by food and pharmaceutical industries. The present work regards the comparative assessment of in vitro propagated and commercially available oregano tissue natural products. This study includes their secondary metabolites’ biosynthesis, antioxidant properties, and anticancer activities. The optimization of callus induction from derived oregano leaf explants and excessive oxidative browning was performed using various plant growth regulators, light conditions, and antioxidant compounds. The determination of oregano callus volatiles against the respective molecules in maternal herbal material was performed using gas chromatography–mass spectrometry (GC/MS) analysis. In total, the presence of twenty-seven phytochemicals was revealed in both leaf and callus extracts, from which thirteen molecules were biosynthesized in both tissues studied, seven compounds were present only in callus extracts, and seven metabolites only in leaf extracts. Carvacrol and sabinene hydrate were the prevailing volatiles in all tissues exploited, along with alkanes octacosane and triacontane and the trimethylsilyl (TMS) derivative of carvacrol that were detected in significant amounts only in callus extracts. The MTT assay was employed to assess the in vitro cytotoxic properties of oregano extracts against the epithelial human breast cancer MDA-MB-231 and the human neuroblastoma SK-N-SH cell lines. The extracts displayed concentration and time-dependent responses in cell proliferation rates.
