“…Endogenous antioxidant system, especially the enzymes SOD, CAT, and GPx as well as the non-enzymatic antioxidant compound GSH (Aristatile et al, 2015) play an important role in protecting cells against oxidative damage. Catechins and carvacrol stimulated the endogenous antioxidant system and reduced the effects of free radical production on cells and tissues in calves (de Paris et al, 2020) and in Jersey cows during the transition period (Vizzotto et al, 2021). These effects were partially confirmed in the present study, as greater activity of CAT and higher concentration of GSH were observed in OR and GT groups, respectively.…”

We aimed to evaluate the effects of the addition of oregano (Origanum vulgare) or green tea (Camellia sinensis L.) extracts (separately and associated) on feed intake, milk production, and hematological and antioxidant profiles of dairy cows. For that purpose, 16 Holstein and 16 Holstein-Gyr cows with 526.3±10.2 kg and within the first third of lactation were distributed according to a complete block design with measurements repeated in time. Treatments were control (CON), addition of 0.056% of oregano extract (OR), addition of 0.028% of green tea extract (GT), addition of a mixture of OR and GT extract (0.056% each) in the diet (MIX). Hematological and antioxidant profiles were monitored. Data were subjected to ANOVA, with block, treatment, days, and their interactions considered as fixed effects and animal and the residue as random effects. In Holstein cows, GT increased feed intake and milk yield compared with CON; in Holstein-Gyr crossbred cows, OR showed increased intake and GT increased milk yield compared with CON. Compared with CON, GT and OR decreased eosinophils concentration; OR showed the highest neutrophils concentration and neutrophils to leukocyte ratio. Compared with CON, OR presented increased catalase (CAT) activity, while GT increased the reduced glutathione concentration. The MIX treatment reduced CAT activity compared with OR, presented the lowest concentration of oxidized dichlorofluorescein in the erythrocytes (DCFER) and plasma (DCFPLA), and increased eosinophils concentration compared with GT and OR. Extracts differently affected feed intake and milk yield depending on genetic group. Feeding green tea and oregano extracts separately or associated distinctly affects the antioxidant indicators of lactating dairy cows.

“…In addition, MAPs, such as Origanum vulgare subsp. Hirtum, Foeniculum vulgare Mill, Pimpinella anisum L., and their extracts can be used as a novel feed additive in turkey production, having beneficial effects, such as food microbial safety or even can enhance production performance [ 114 ] as “green pesticides” to limit the use of hazardous synthetic pesticides (the case of Heracleum persicum and Achillea millefolium essential oil against Plodia interpunctella , citronellal from Cymbopogon winterianus against Spodoptera frugiperda larvae, or rosemary oil applied against Agriostes obscurus larvae) [ 115 ] or in the zootechnological field to enhance animals’ performance and health [ 116 ]. Moreover, purified bioactive compounds from MAPs (such as Calendula officinalis L., Lavandula vera DC, Artemisia absinthium L.) or even plant extracts (as a whole) have potential applications in the cosmetic industry, which nowadays is focused on new technologies and explores alternative sources of raw materials; the trends in this direction are based on the use of plant-origin components having polyfunctional properties and long-lasting effects [ 117 ].…”

Natural compounds obtained from different medicinal and aromatic plants have gained respect as alternative treatments to synthetic drugs, as well as raw materials for different applications (cosmetic, food and feed industries, environment protection, and many others). Based on a literature survey on dedicated databases, the aim of the present work is to be a critical discussion of aspects regarding classical extraction versus modern extraction techniques; possibilities to scale up (advantages and disadvantages of different extraction methods usually applied and the influence of extraction parameters); and different medicinal and aromatic plants’ different applications (medical and industrial applications, as well as the potential use in nanotechnology). As nowadays, research studies are directed toward the development of modern, innovative applications of the medicinal and aromatic plants, aspects regarding future perspectives are also discussed.

“…Previous studies reported that using oregano essential oils or green tea polyphenols decreased the frequency or severity of diarrhea in dairy calves (Maciej et al, 2016;Katsoulos et al, 2017). Furthermore, Paris et al (2020) reported that calves receiving milk from cows supplemented with oregano or green tea extracts improved their redox status. On the other hand, observed that oregano and green tea extracts anticipated the first rumination of dairy calves, although they did not modify weight gain, diarrhea incidence, or general health conditions.…”

“…Antibiotics and ionophores are used to deal with some of these problems; however, society has concerns about the safety of their use. For this reason, plant extracts are being increasingly used in ruminant feed, including pre-weaned calves (Maciej et al, 2016;Paris et al, 2020). The redox status of these animals has been associated with health conditions as many free radicals are continuously produced in the cells with the potential to provoke oxidative damage to internal organs.…”

“…On the other hand, observed that oregano and green tea extracts anticipated the first rumination of dairy calves, although they did not modify weight gain, diarrhea incidence, or general health conditions. The authors cited provided plant extracts for calves from birth to 10 ( Katsoulos et al, 2017) or 60 days of life (Heisler et al, 2020;Paris et al, 2020), as it comprises the most critical phase of life for calves, as well as the pre-weaned period.…”

This study aimed to evaluate the effects of the separate provision of green and oregano tea extracts on the biomarkers of the redox state and health condition in pre-weaned Jersey calves from birth to 60 days of life. Two experiments following the complete randomized design with measures repeated in time were carried out using 38 Jersey calves (17 and 21 calves in experiments 1 and 2, respectively). Calves were distributed according to date of birth into one of three groups: control (CON) - with no addition of extracts; oregano extract (OE) - addition of 70 mg of oregano extract/kg of body weight (BW) and green tea extract (GT) - addition of 35 mg of green tea extract/kg of BW. Eight biomarkers of the redox state were evaluated on days 1, 30, and 60 after birth, and variables measured on day 1 were used as covariates. Body temperature and occurrence of diarrhea were evaluated every two days. Regarding the main results, the supply of oregano extract reduced the concentration of oxidizing biomarkers, such as DCFP (oxidation of dichlorofluorescein in plasma) and carbonyl, and increased the activity of antioxidant enzymes, such as GPx and catalase. Green tea extract only reduced DCFP and tended to improve catalase activity. Calves remained healthy (no fever and only a few days with diarrhea), and plant extracts did not improve their health condition. The addition of green tea and oregano extracts into the diet has a positive effect on redox status in pre-weaned Jersey calves.
