Wells CW. Effects of essential oils on economically important characteristics of ruminant species: A comprehensive review. ANIMAL NUTRITION (ZHONGGUO XU MU SHOU YI XUE HUI) 2024; 16:1-10. [PMID: 38131027 PMCID: PMC10731003 DOI: 10.1016/j.aninu.2023.05.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 01/10/2022] [Revised: 03/27/2023] [Accepted: 05/04/2023] [Indexed: 12/23/2023]
Abstract
Essential oils derived from plants can provide biological impacts to livestock species. Scientific studies researching essential oils in livestock have investigated various essential oils for prevention and treatment of microbial infection and parasites as well as to enhance milk production, animal performance and rumen function. Despite the availability of several commercial products containing essential oils to promote animal health and production, the vast amount of essential oils, modes of application, and effective concentrations of the essential oils suggest there are more opportunities for essential oils to be utilized in commercial livestock production and veterinary medicine. The objective of this review is to contribute to the understanding of the value that essential oils can provide to the ruminant diet and to examine the biological impact of various essential oils on economically important production traits of ruminant species.

Abstract
The nutrition and active compounds from plants are very important to regulate the immunity of the body by improving the oxidant and inflammatory response. In this article, we aimed to investigate the nutritional profile and the phytochemical compositions of Adonis coerulea; the functional characteristics and its possible mechanism were studied. Results showed that the aerial parts of Adonis coerulea (ACAP) contained the abundant of proteins (16.15%) and the minerals (31.02.09 mg/100 g dried ACAP); promisingly, the content of essential amino acids (8.25%) and fatty acids (13,220.45 mg/100 g) also were obtained to regulate the immunity and prevent some chronic diseases. The methanol extract of ACAP played the anti-inflammatory activity via peroxisome proliferators-activated receptor (PPAR)-γ-mediated nuclear factor kappa B (NF-κB) pathway. Among the 18 identified compounds, linolenic acid from fatty acids and licochalcone A were active compounds by inhibiting nitric oxide (NO) production of RAW264.7 cells induced by lipopolysaccharide (LPS). The alleviation of inflammatory response results in the decrease of oxidative stress; ACAP showed the antioxidant activity by attenuating antioxidant enzymes, improving mitochondrial membrane potential and reactive oxygen species. These results highlight the potential of A. coerulea as a source of active ingredients in pharmaceutical industries.

Abstract
In our previous studies, we found that as the active gradients of Adonis coerulea, cardenolides and cardiac glycosides presented toxicity against mites by inhibiting Na+-K+-ATPase. In this paper, after evaluating the acaricidal activity of the commercial cardiac aglycones/glycosides, serials of novel strophanthidin derivatives were designed and synthesized with an efficient and simple route under mild conditions, and their toxicity against mites, the cytotoxicity and inhibitory effect on Na+-K+-ATP enzyme in PC12 cells were investigated. Results showed among of all compounds, including 9 commercial agent and 32 synthesized strophanthidin derivatives, QXG-1 presented the strongest toxicity against mites with the LC50 value of 320.0 μg/mL. C-19 group of strophanthidin substituted with glycinemethylester would increase the toxicity against mites, and the hydroxyl group at C-5 play the vital role in terms of the toxicity. At the given concentration, QXG-1 displayed the safety against PC12 (10.0 μg/mL) in vitro and mice (3.2 mg/kg) in acute toxicity test, and strong inhibitory effect on Na+-K+-ATPase. It could be used as a promising acaricidal agent. This study lays the foundation to develop of QXG-1 as a relatively safe and alternative acaricidal agent.

Abstract
Adonis coerulea Maxim. as a folk medicine, presented acaricidal acitvity. However, the mode of action and active compounds were unclear. In this study, using proteomics and surface plasmon resonance (SPR) technology the mode of action and active compounds of A. coerulea were investigated, as well as a sensitive and environmentally friendly analytical method developed. Proteomics analysis results showed that after treatment of mites with A. coerulea methanol extract (MEAC), 135 proteins were differentially expressed, most of them enriched in the myocardium pathway and participated in the function of the inflated cystic organ. Na+-K+-ATPase may be a potential target. Then, it was used as a target to capture the compounds from the extract using a SPR test. Twelve compounds were found, five compounds, namely ellagic acid, ouabain, convallatoxin, strophanthidin and cymarin presented the higher affinity with Na+-K+-ATPase in molecular docking test. Further study showed that the latter four compounds presented the stronger cytotoxicity and the inhibitory effect on Na+-K+-ATPase with IC50 values ranging with 2.38-0.56 μg/mL, and also showed toxicity against Psoroptes cuniculi. These results indicated that MEAC presented toxicity against mites by inhibiting Na+-K+-ATPase, and cardiac glycosides may be active compounds of this plant in terms of its acaricidal activity. Only 10 g of plant was used to investigate its active compounds. This study lays the foundation for developing sensitive methods for active compound detection.

Abstract
Adonis coerulea Maxim. presents acaricidal activity in vitro and in vivo, and inhibits AChE and other enzymes activities. However, the active compounds against Psoroptes cuniculi were still unclear. AChE, a common acaricidal and insecticidal target, plays a key role in neural conduction of mites. In this study, using surface plasmon resonance (SPR) technology, AChE was used as a target to capture the compounds from A. coerulea methanol extract (MEAC). After calculating the affinity with molecular docking, the inhibitory effect of compounds against AChE was studied. Results showed that 27 compounds were captured by AChE and identified from MEAC by LC-MS/MS. Among of these compounds, eight compounds presented the high affinity with AChE and high scores in molecular docking assay, especially for silibinin (-12.19 kcal/mol) and vitexin (-11.72 kcal/mol). Further studies showed that although these compounds have the weak cytotoxicity against C6/36 cells, silibinin, quercetin and corilagin could inhibit AChE activity with IC50 values of 40.11 μg/mL, 46.15 μg/mL and 50.98 μg/mL, respectively. These results indicated that silibinin, quercetin and corilagin may be responsible for AChE inhibition which contributes to the acaricidal properties of A coerulea. This study lays the foundation for developing sensitive and sustainability methods for active compound detection from plants.

Abstract
BACKGROUND Treatment of Psoroptes ovis in cattle is limited to topical acaricides or systemic treatment with macrocyclic lactones. Treatment failure of macrocyclic lactones has been reported. The aim of this study was to evaluate a potential alternative treatment against P. ovis. METHODS The acaricidal activity against P. ovis of four plant-derived essential oil components, i.e. geraniol, eugenol, 1,8-cineol and carvacrol, was assessed in vitro and in vivo. In vitro contact, fumigation and residual bioassays were performed. In addition, 12 Belgium Blue cattle were artificially infested and treated topically once a week for three successive weeks with carvacrol in Tween-80 (treatment group) or with Tween-80 alone (control). The efficacy of carvacrol was determined by the reduction in lesion size and mite counts. Six additional animals were topically treated with carvacrol to assess local adverse reactions. RESULTS Three components showed a concentration-dependent acaricidal activity in a contact assay, with LC50 of 0.56, 0.38 and 0.26% at 24 h for geraniol, eugenol, and carvacrol, respectively. However, 1,8-cineol showed no activity at any of the tested concentrations in a contact bioassay. In a fumigation bioassay, carvacrol killed all mites within 50 min after treatment, whereas geraniol, eugenol and 1,8-cineol needed 90 to 150 min. Following a 72 h incubation period in a residual bioassay, carvacrol killed all mites after 4 h of exposure to LC90, while geraniol and eugenol killed all mites only after 8 h exposure. Based on these results, carvacrol was further assessed in vivo. Mite counts in the treatment group were reduced by 98.5 ± 2.4% at 6 weeks post-treatment, while in the control group the mite population had increased. Topical application of carvacrol only caused mild and transient erythema 20 min after treatment. No other side effects were observed. CONCLUSIONS Considering the strong acaricidal activity of carvacrol in vitro and in vivo and the mild and transient local side effects, carvacrol shows potential as an acaricidal agent in the treatment of P. ovis in cattle.

Abstract
Plant essential oils and its chemical compositions are commonly applied in medicinal and other industries due to their broad advanced pharmacological activities. In the present study, we systematically evaluated the acaricidal activities of twelve compounds of essential oils against Psoroptes cuniculi in vitro and in vivo. In addition, to support the clinic uses, their toxicities against immortalized human keratinocytes (HaCaT) and human liver cells (HL-7702) and skin irritation were studied for evaluating the liver and skin safety. The possible mechanism of action of certain chemical were investigated by determining the inhibitory activities against cytochrome P450 (P450) acetylcholinesterase (AChE) and glutathione-S-transferase (GST). Among all tested compounds, eugenol exhibited the best acaricidal activity with LC50 value of 56.61 μg/ml in vitro. Meanwhile, after the treatment of eugenol for five times within 10 days, the P. cuniculi were eliminated in the naturally infested rabbits, no skin irritation was found in rabbits treated by eugenol. Moreover, eugenol presented no or weak cytotoxicity against HaCaT cells and HL-7702 cells with IC50 values of greater than 100 μg/ml. Furthermore, the moderate inhibitory activities of eugenol against mites P450 and AChE were demonstrated. Above results indicated that eugenol presented the promising acaricidal activity against P. cuniculi in vitro and in vivo, is safe for both humans and animals at the given doses. This work lays the foundation for the development of eugenol as an environmentally friendly acaricide agent.

Abstract
The genus Adonis L. (Ranunculaceae), native to Europe and Asia, comprises 32 annual or perennial herbaceous species. Due to their cardiac-enhancing effects, Adonis spp. have long been used in European and Chinese folk medicine. These plants have been widely investigated since the late 19th century, when the cardiovascular activity of Adonis vernalis L. was noted in Europe. The present paper provides a review of the phytochemistry, biological activities and toxicology in order to highlight the future prospects of the genus. More than 120 chemical compounds have been isolated, with the most important components being cardiac glycosides as well as flavones, carotenoids, coumarins and other structural types. Plants of the genus, especially A. vernalis L. and A. amurensis Regel & Radde, their extracts and their active constituents possess broad pharmacological properties, including cardiovascular, antiangiogenic, antibacterial, antioxidant, anti-inflammatory and acaricidal activities, and exhibit both diuretic effects and effects on the central nervous system. However, most plants within the 32 species have not been comprehensively studied, and further clinical evaluation of their cardiovascular activity and toxicity should be conducted after addressing the problem of the rapidly decreasing resources. This review provides new insight into the genus and lays a solid foundation for further development of Adonis.

Abstract
A series of 3-aryl propionic esters and their analogues were designed and evaluated for acaricidal activity in vitro against Psoroptes cuniculi, a mange mite. The structure–activity relationship (SAR) was also discussed. The results showed that 6 compounds possessed the excellent activity (LC50 = 0.17–0.24 mM, LT50 = 1.5–2.9 h), superior to ivermectin (LC50 = 0.28 mM, LT50 = 8.9 h) (P < 0.05), a standard drug. Furthermore, 7 compounds showed the good activity (LC50 = 0.25–0.37 mM, LT50 < 3.9 h), slightly lower or close to that of ivermectin. One compound displayed super-fast acaricidal property, far superior to ivermectin. SAR analysis found that the ester group is vital for the activity and the small steric hindrance adjacent to the ester group is advantageous for the high activity. The <C4 linear alcohol esters can give the higher activity. The substituents on the 3-phenyl ring or replacement of the 3-phenyl with heterocyclic aryl generally decreases the activity. The position of the ester group in the ester chain also influences the activity, where the 3-phenyl propionate and the benzoate had the highest and lowest activity, respectively. Thus, 3-arylpropionates emerged as new and promising high-efficient acaricide candidates.

Abstract
As important secondary plant metabolites, naphthoquinones exhibit a wide range of biological activities. However, their potential as sustainable alternatives to synthetic acaricides has not been studied. This study for the first time investigates the acaricidal activity of naphthoquinones against Psoroptes cuniculi in vitro. Furthermore, the in vivo activity, the skin irritation effects, the cytotoxicity and the inhibitory activities against mite acetylcholinesterase (AChE) and glutathione S-transferase (GST) of the two compounds that displayed the best insecticidal activity in vitro were evaluated. Among fourteen naphthoquinones and their analogs, juglone and plumbagin were observed to possess the strongest acaricidal activities against P. cuniculi with LC50 values of 20.53 ppm and 17.96 ppm, respectively, at 24 h. After three treatments, these two chemicals completely cured naturally infested rabbits in vivo within 15 days, and no skin irritation was found in any of the treated rabbits. Compared to plumbagin, juglone presented no or weak cytotoxicity against HL-7702 cells. Moreover, these two chemicals significantly inhibited AChE and GST activity. These results indicate that juglone has promising toxicity against P. cuniculi, is safe for both humans and animals at certain doses, and could be used as a potential alternative bio-acaricide for controlling the development of psoroptic mange in agricultural applications.

Bioactivity and structure-activity relationship of cinnamic acid derivatives and its heteroaromatic ring analogues as potential high-efficient acaricides against Psoroptes cuniculi. Bioorg Med Chem Lett 2017; 28:1149-1153. [PMID: 29496368 DOI: 10.1016/j.bmcl.2017.08.051] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2017] [Revised: 08/14/2017] [Accepted: 08/19/2017] [Indexed: 10/19/2022]
Abstract
A series of cinnamic acid derivatives and its heteroaromatic ring analogues were synthesized and evaluated for acaricidal activity in vitro against Psoroptes cuniculi, a mange mite. Among them, eight compounds showed the higher activity with median lethal concentrations (LC50) of 0.36-1.07mM (60.4-192.1µg/mL) and great potential for the development of novel acaricidal agent. Compound 40 showed both the lowest LC50 value of 0.36mM (60.4µg/mL) and the smallest median lethal time (LT50) of 2.6h at 4.5mM, comparable with ivermectin [LC50=0.28mM (247.4µg/mL), LT50=8.9h], an acaricidal drug standard. SAR analysis showed that the carbonyl group is crucial for the activity. The type and chain length of the alkoxy in the ester moiety and the steric hindrance near the ester group significantly influence the activity. The esters were more active than the corresponding thiol esters, amides, ketones or acids. Replacement of the phenyl group of cinnamic esters with α-pyridyl or α-furanyl significantly increase the activity. Thus, a series of cinnamic esters and its heteroaromatic ring analogues with excellent acaricidal activity emerged.

Abstract
Bacillus thuringiensis is a bacteria known for its bioinsecticidal toxins and it has been proposed as an alternative in the treatment of several parasites that infect domestic animals (helminths, ticks, mites). In this work, we evaluated the clinical efficiency of the Bacillus thuringiensis GP532 strain in the treatment of six rabbits naturally infested with the P. cuniculi mite. GP532 extract (10mg/ml) was applied by aspersion in both pinna, with a second application after seven days, and the therapeutic effect was measured in both qualitative and quantitative manner. GP532 application resulted in a decreased infestation rate, which was observed as early as 3days post-treatment. At day 14, a decrease from 4.66±0.61 to 0.50±0.10 in the left pinna and from 1.66±0.21 to 0.66±0.16 (P<0.05) in the right pinna was observed. This response was comparable to the commercial drug Ivermectin, which induced a decreased infestation rate from 4.00±0.51 to 0.16±0.10 in the left pinna and from 4.66±0.80 to 0.25±0.11 in the right pinna (P<0.05). At day 30 post-treatment, GP532 decreased the total infested area by 76.80±16.06%, whereas Ivermectin resulted in a 97.41±0.99% decrease. Neither treatment produced irritation or macroscopic lesions. Our results show that the B. thuringiensis GP532 strain has a therapeutic potential in the treatment of psoroptic mange in rabbits.

Abstract
In this paper, the acaricidal activities of Rhododendron nivale Hook. f. and its main compound, δ-cadinene were investigated, and the chemical composition of the essential oil was analyzed. The results showed that among aqueous, 70% ethanols, acetic ether, chloroform, petroleum ether and essential oil extracts from the shoots and leaves, the essential oil showed the best in vitro acaricidal activity against adult P. cuniculi, which occurred in a concentration- and time-dependent manner. The median lethal time (LT50) values of four concentrations (33.33-4.17mg/ml) of the essential oil ranged from 1.476 to 25.900h, respectively. After the treatment of P. cuniculi with the essential oil and ivermectin, infected rabbits were free of scabs or secretions in the ear canal by day 20. Then, the percent yield of essential oil from the leaves and shoots was 2.45% (w/w), which includes 50 compounds. The primary component identified was terpenes, and among of compounds identified from the essential oil of R. nivale the highest relative content was δ-cadinene, which also presented the marked acaricidal activity against Psoroptes cuniculi in vitro. These findings provide evidence for the use of acaricides as a traditional medicine and indicate that the essential oil and δ-cadinene could be used to control mites in livestock.

Abstract
The aim of the present study was to investigate the acaricidal activity of Ligularia virgaurea. An extract was prepared by refluxing with ethanol and steam distillation, and its toxic effect was tested in vitro against Sarcoptes scabiei. The data from the toxicity tests were analyzed using a complementary log-log (CLL) model. The ethanol extract exhibited strong acaricidal activity against these mites; at a concentration of 2 g/ml it killed all S. scabiei within 2 h and at 1 g/ml it killed all S. scabiei within 6 h. Similarly, 2, 1, 0.5 and 0.25 g/ml concentrations of the extract had strong toxicity against S. scabiei, with median lethal time (LT50) values of 0.716, 1.741, 2.968 and 4.838 h, respectively. The median lethal concentration (LC50) values were 1.388, 0.624, 0.310 and 0.213 g/ml for Scabies mite in 1, 2, 4 and 6 h, respectively. The results indicate that the L. virgaurea extract has strong acaricidal activity and may be exploited as a novel treatment for the effective control of acariasis in animals.

Abstract
BACKGROUND Animal acariasis is one of the important veterinary skin diseases. Chemical drugs have been widely used to treat and control this kind of disease. But many chemicals control could increase resistance in target species, toxicity and environmental hazards. We found that the 9-oxo-10, 11-dehydroageraphorone (euptox A) extracted from E. adenophorum has strong toxicity against P. cuniculi in vitro, but the in vivo acaricidal actions of euptox A have yet to be investigated. RESULTS A 14-day experiment was performed using rabbits that were naturally infested with P. cuniculi on a farm. Rabbits were randomly divided into five groups; animals in groups A, B and C were treated in each ear topically with 4.0 ml of 2.0 and 1.0 g/L (w/v) euptox A, respectively. Animals in groups D and E were treated with ivermectin (by injection; positive controls) and glycerol with water only (by embrocation; negative controls), respectively. Each rabbit was treated twice with separate treatments on days 0 and 7. Rabbits were observed daily and detailed examinations were performed on days 0, 7 and 14, to inspect the presence or absence of mites and scabs/crusts. Seven days after the initial treatment, the mean clinical scores (presence of scabs/crusts) decreased from 3.48, 3.37, 3.43 and 3.45 to 0.37, 0.42, 0.78 and 0.38 in the ears of animals in groups A, B , C and D, respectively, which were similar to the observations recorded in the positive control rabbits. However, the clinical score for negative control rabbits did not increase significantly (P > 0.05) during the experiment, and this changed from 3.32 to 3.37 in the ears, and there were no significant differences in clinical efficacy between left and right ears. After two treatments (0 and 7 d), the rabbits in groups A, B, C and D had recovered completely 14 days after the last treatment and no recurrences of infection were observed. CONCLUSIONS These results indicate that euptox A was potent compounds for the effective control of animal P. cuniculi in vivo.

Abstract
Background Psoroptes cuniculi can parasitise the ear canal of the rabbit, and cause the afflicted animals to cease feeding and become severely debilitated, sometimes resulting in death. In this study, we examined the oxidative status and inflammatory level of the peripheral blood of rabbits infested with Psoroptes cuniculi and investigated the pathogenesis of this disease. Methods A total of 24 rabbits were divided into a healthy rabbit group and two infested rabbit groups. After weighing the rabbits, approximately 5 ml of blood was obtained from each animal. Then, the blood serum was extracted and used to assess the levels of antioxidant enzymes and inflammatory factors. Results Compared to the healthy rabbits, the activities of catalase and glutathione-S-transferase and the level of malonyldialdehyde were increased, but the activity of superoxide dismutase was reduced in the infested rabbits. At the same time, a variety of inflammatory cells were activated, and the levels of inflammatory factors such as prostaglandin E2, interleukin-6, interleukin-8 and transforming growth factor-β1 were increased in peripheral blood. Conclusion Animal acariasis was associated with immunosuppressive disorders and inflammatory reaction. These results advance our understanding of the pathogenesis of Psoroptes cuniculi infestation in rabbits and can help guide the effectual treatment of this disease in clinics.

The acaricidal activity of the 9-oxo-10,11-dehydroageraphorone (euptox A), a cadenine sesquiterpene from Eupatorium adenophorum (E. adenophorum) against Sarcoptes scabiei and Psoroptes cuniculi was tested in vitro. A complementary log-log (CLL) model was used to analyze the data of the toxicity tests in vitro. The results showed euptox A had strong toxicity against mites, killing all S. scabiei at 3 and 4 mg/ml (m/v) concentration, while 4 mg/ml euptox A was also found to kill all P. cuniculi within a 4 h period. Similarly, 2, 3 and 4 mg/ml concentration of euptox A had strong toxicity against S. scabiei, with median lethal time (LT50) values at 0.687, 0.526, 0.326 h, respectively. 3 mg/ml and 4 mg/ml showed strong acaricidal action against P. cuniculi; the LT50 values were 0.693 and 0.493 h, respectively. The median lethal concentration (LC50) values were 1.068 mg/ml for Scabies mite and 0.902 mg/ml for P. cuniculi in 2 h. The results indicate that euptox A has strong acaricidal activity and may exploit as novel drugs for the effective control of animal acariasis.
