The aim of the study was to determine the efficiency of a formulation containing essential oils from Origanum vulgare (Lamiacea) and Citrus spp. (Citraceae) in limiting the prevalence and intensity of parasitic invasions in ewes kept in an indoor management system. The study material was a group of 222 mother ewes of Polish Lowland breed. During the entire experiment, the animals were kept in an indoor management system with uniform environmental conditions. On the basis of the parasitologic analysis, the flock was divided into three groups. All groups were uniform from the perspective of genetic traits, age and environmental conditions. The differentiating factor was the addition of a preparation containing essential oils from Origanum vulgare and Citrus spp. in the dose of 4 kg/ton of feed. Group 1 – control group, non-supplemented diet (74 mother ewes); Group 2 – supplemented diet from third month of pregnancy to lambing (73 mother ewes); Group 3 – supplemented diet from third month of pregnancy to weaning (75 mother ewes). The experiment involved parasitologic tests aimed at the determination of prevalence and intensity of invasions of gastrointestinal parasites in mother ewes. The study material was faeces collected from the rectum of mother ewes before the start of the experiment and on day 2, 28, 42, 56 and 70 after lambing. On the basis of the observations, it was shown that continuous use of the preparation during the whole experimental period had a beneficial impact on reducing the prevalence of invasions of Eimeria spp. and Capillaria. However, it must be stressed that both the prevalence and the intensity of parasitic invasions in the studied flock was relatively low, and so the use of such a preventive method was feasible.

The aim of the study was to determine the degree of parasitic invasion at various physiological stages, as well as tracing the dynamics of parasitic invasions in a flock of sheep kept in the combined indoor-pasture management system. The observations were performed on 224 mother ewes of the synthetic SCP prolific meat line over the course of two years. The animals were kept in the combined indoor-pasture management system with uniform feeding and environmental conditions and were under continuous animal husbandry and veterinary supervision. The ewes participating in the experiment were not wormed in the year preceding the experiment and during the observations. The experiment involved parasitologic tests aimed at the determination of abundance and prevalence of invasions of gastrointestinal parasites in mother ewes. The study material was faeces collected from the rectum in the following stages: pregnancy (November), day 2, 28, 42 and 56 after lambing, drying off (day 100 after lambing) and rest (between dry-off and mating). In the analysis of the results of the study it can be noted that, in most cases, the highest prevalence and abundance levels are observed in the infertility period. Moreover, the period of pregnancy and lambing was a crucial one. On the other hand, the lowest abundance and prevalence levels in the majority of cases were observed on day 28 and 42 after lambing. The results of the study should be taken into consideration during the development of prevention strategies limiting parasitic invasions in sheep flocks. Adjusting chemotherapy to the most important periods of parasitic invasions will enable a more efficient fight against parasites. It should also reduce the excessive use of chemical preparations, which is crucial due to the increasing resistance of parasites. Apart from the aforementioned actions, farmers should pay attention to supporting immunity by means of feed, especially in the periods of highest vulnerability to invasions. Such actions should lead to the reduction of losses caused by parasitic invasions in sheep flocks.

The aim of the study was to evaluate the influence of preventive activities involving the use of a coccidiostatic product containing Origanum vulgare and Citrus spp. extracts on the slaughter value of lambs from a confined management system. The study material was a group of 222 mother ewes and 276 lambs of the Polish Lowland breed. During the whole experiment the animals were kept in a confined management system, indoors, with uniform environmental conditions. On the basis of the parasitological analysis the flock was divided into three groups similar in both the intensity and the extensity of parasitic infections: Group 1: a control group, whose diet was not supplemented (74 mother ewes, 87 lambs); Group 2: diet supplemented with OILIS SD, a product with coccidiostatic effect, from the third month of pregnancy to lambing the lambs were fed like the control group (73 mother ewes, 105 lambs); Group 3: diet supplemented with OILIS SD, a product with coccidiostatic effect, from the third month of pregnancy to lambing, the lambs receiving feed with OILIS SD starting from the 14th day of life (75 mother ewes, 84 lambs). Out of 276 lambs included in the experiment, 18 rams and 18 ewes representing all the observed groups were chosen for slaughter. The lambs were slaughtered around day 100 of their life (± 6 days). The observations showed that the animals from Group 3, in which the feed of both mother ewes and lambs was supplemented with a coccidiostatic product, were characterized by a higher slaughter weight: 30.80 kg, in comparison to 27.80 kg in Group 1 and 26.90 kg in Group 2, which has been confirmed as statistically significant (p ≤ 0.05). This corresponded to the achieved carcass weight. The highest average hot carcass weight (13.36 kg) was noted in Group 3, while the parameters for Group 1 (11.88 kg) and Group 2 (11.28 kg) were significantly lower (p ≤ 0.05). The conducted post-slaughter analysis clearly showed that the coccidiosis prevention measure consisting in a product containing the ether oils of Origanum vulgare (Lamiacea) and Citrus spp. (Citraceae) has a beneficial influence on the slaughter value of lambs, and results both in a higher carcass weight and the weights of specific cuts and tissues..

Abstract This study aims to determine the effects of essential oils of Origanum dubium (DUB), Origanum vulgare subsp. hirtum (HIR), and Lavandula angustifolia (LAV) on lipid profiles and liver biomarkers in athletes. Thirty-four trained athletes were randomly assigned to one of three experimental groups or the control group (CON). The concentrations of serum lipids and liver biomarkers were assessed before and after the 14-day essential oil intervention. Gas chromatography-mass spectrometry analysis showed 68.0 and 82.1% carvacrol in DUB and HIR, respectively, and 34.50% linalyl acetate and 33.68% linalool in LAV essential oils. One-way analysis of covariance (ANCOVA) indicated a significant difference (p = 0.001) among the groups for high-density lipoprotein cholesterol (HDL-C) when the associated preintervention values were used as a covariate. The related pairwise comparisons revealed that DUB (p = 0.001) and HIR (p = 0.024) had greater HDL-C values than CON. From the two-way ANOVA, an interaction between time (before vs. after) and the groups (DUB vs. HIR vs. LAV vs. CON) was found for HDL-C (p = 0.030). Findings indicated a significant increase in DUB (p = 0.0001) and HIR (p = 0.010) for HDL-C, and there was a significant decrease in DUB (p = 0.023) for low-density lipoprotein cholesterol. However, there was no difference in total cholesterol, triglycerides, and all liver biomarkers.

The aim of the study was to evaluate the efficiency of various methods of antiparasitic prophylaxis using a conventional chemical agent and a formulation containing plant essential oils. The animal material consisted of 139 mother ewes of two synthetic prolific meat lines: bcp and scp. During the whole experiment, the animals were kept in indoor management system with uniform environmental conditions. The experiment included ewes lambing within the period of 12 consecutive days. Using the results of coproscopic tests performed after lambing, the animals were randomised into three study groups: Group A - wormed with an albendazole-containing preparation (50 sheep), Group L - receiving a lick with antiparasitic essential oils (48 sheep) and Group C - control group, not wormed (41 sheep). Two antiparasitic agents were used. A chemical agent containing albendazole. The procedure was performed on day 35 after lambing, and the dose administered was 5 mg of the active substance per kg bw, which corresponded to 0.5 ml, orally, per 10 kg bw. A natural worming agent was administered in the form of licks containing essential oils of Thymus vulgaris, Allium sativum, Artemisia absinthium, Dryopteris filixmax, Tanacetum vulgare, Cucurbita pepo, Chenopodium ambrosioide, Inula helenium, Peumus boldo, Corallina rubens. The licks were made available to animals on day 21 after lambing. The experiment involved parasitologic tests aimed at the determination of estimated intensity (based of OPG and EPG data) and prevalence of invasions of gastrointestinal parasites in mother ewes. The study material was faeces collected from the rectum on the following dates: after lambing, and on day 28, 42, 56, 70 and 100 of lamb's life. The observations proved that the formulation based on natural plant ingredients had a beneficial influence on the reduction of prevalence of Eimeria and Capillaria. It was also shown that the albendazole-containing chemical preparation is highly efficient in reducing the prevalence of Trichostrongylidae, Nematodirus, as well as Capillaria.

Background and Aim: Extending the shelf life of foods is an essential concept in food safety. Most of the time, foods deteriorate through the growth of microorganisms or oxidation process. Essential oils (EOs) derived from plant material have well-documented antioxidant and antibacterial activity. This study aimed to evaluate the effect of Zataria multiflora Boiss EO (ZEO) and Mentha piperita EO (MEO) on the chemical stability of minced meat during storage at 7°C. Materials and Methods: Total phenolic content, β-Carotene bleaching test, ferric reducing antioxidant potential assay, and 2,2-Diphenyl-1-picrylhydrazyl radical scavenging activity were used to determine the antioxidant potential of EOs. Five different groups including control, ZEO 0.3%, ZEO 0.5%, MEO 0.3%, and MEO 0.5% were designed to assess the chemical stability of minced meat by measuring pH, thiobarbituric acid (TBA), total volatile base nitrogen (TVBN), and peroxide value (PV). Results: pH did not have any significant change during storage. TBA values in the control group were significantly higher than the treatment groups, especially from the 5th day of storage. TVBN in the treatment group was significantly lower than the control group during storage. PV values in the treatment group were significantly lower than the control group during storage. Conclusion: Results indicate that ZEO and MEO had an excellent antioxidant activity and retarded the spoilage process in minced meat. Keywords: antioxidant, Mentha piperita, minced meat, Zataria multiflora Boiss.

Abstract Background Essential oil of Rosa × damascena Herrm. is one of the most valuable and important raw materials for the flavor and fragrance industry. The cultivation of this plant has ancient origins, and Kashan was one of the first mountainous regions of Iran dealing with the cultivation of R. × damascena. In this study, both chemical composition and antimicrobial activity of different rose essential oils obtained from five mountainous areas of Kashan region (Maragh, Qamsar, Sadeh, Javinan, and Kamoo) has been investigated along with the influence of the environmental conditions on these properties. Results Results showed that yield and chemical composition of essential oils obtained from Rosa × damascena were significantly affected by the collection area. In particular, the yield of oils varied from ~0.08 to ~0.132% and citronellol (36.70-9.18%), geraniol (12.82-0.47%), nonadecane (22.73-10.36%), heneicosane (31.7-11.43%), and 1-nonadecene (6.03-3.93%) have been detected as main compounds in all the plants collected, but at different concentrations depending on the collection area. The best fragrance and the highest yield were found in the oil from Kamoo area. Similarly to the chemical composition, the antimicrobial activity of the essential oils was affected by their origin, and essential oil obtained from plants collected from Kamoo area disclosed the highest antibacterial and antifungal efficacy. Its inhibition halos were 17.33±0.58 mm against Aspergillus brasiliensis, 15.67±0.58 mm against Staphylococcus aureus, and 12.33±0. 58 mm against Streptococcus pyogenes. Essential oils of R. damascena were also effective against Gram-negative Pseudomonas aeruginosa and they had a MIC value of 62.50 μg/mL irrespective of the collection area (except the oil from Javinan area). On the contrary, the highest antifungal power against Candida albicans yeast was reached using the essential oil obtained from plants collected in Javinan region (MIC and MBC ~62.50 μg/mL). Conclusions Overall results underline the influence of environmental conditions of the different areas of Kashan region, on the chemical composition of and antimicrobial activity of the essential oils of Rosa × damascena. In addition, results disclosed that Kamoo seemed to be the most suitable area for the competitive cultivation of R. × damascena to the intensive production of aromatic flower oil and natural antimicrobial essential oils.

The objective of the present research was to assess the dietary supplementation of three formulations of essential oils (EO) in chickens under heat stress (HS). Day-of-hatch Cobb 500 chicks (n = 500) were randomly distributed into four groups: 1. HS control + control diets; 2. HS + control diets supplemented with 37 ppm EO of Lippia origanoides (LO); 3. HS + control diets supplemented with 45 ppm LO + 45 ppm EO of Rosmarinus officinalis (RO) + 300 ppm red beetroot; 4. HS + 45 ppm LO + 45 ppm RO + 300 ppm natural betaine. Chickens that received the EO showed significant (p < 0.05) improvement on BW, BWG, FI, and FCR compared to control HS chickens. Average body core temperature in group 3 and group 4 was significantly (p < 0.05) reduced compared with the HS control group and group 2. Experimental groups showed a significant reduction in FITC-d at 42 days, a significant increase in SOD at both days but a significant reduction of IFN-γ and IgA compared with HS control (p < 0.05). Bone mineralization was significantly improved by EO treatments (p < 0.05). Together these data suggest that supplemental dietary EO may reduce the harmful effects of HS.

(1) Background: Research on heart rate variability has increased in recent years and the temperature has not been controlled in some studies assessing repeated measurements. This study aimed to analyze how heart rate variability may change based on environmental temperature during measurement depending on parasympathetic and sympathetic activity variations. (2) Methods: A total of 22 volunteers participated in this study divided into an experimental (n = 12) and control group (n = 10). Each participant was assessed randomly under two different environmental conditions for the experimental group (19 °C and 35 °C) and two identical environmental conditions for the control group (19 °C). During the procedure, heart rate variability measurements were carried out for 10 min. (3) Results: Significantly changes were observed for time and frequency domains as well as Poincaré plot variables after heat exposure (p < 0.05). These findings were not observed in the control group, whose conditions between measurements did not change. (4) Conclusions: The reduction of heart rate variability due to exposure to hot conditions appears to be produced mostly by a parasympathetic withdrawal rather than a sympathetic activation. Therefore, if consecutive measurements have to be carried out, these should always be done under the same temperature conditions.
