“…In the study conducted, it was observed that the use of oregano oil in different doses in post-weaned Tuj lambs did not affect live weight gain, daily live weight gain, daily feed consumption, and feed conversion rate. There are many current studies using thyme and other plant extracts that support the results of our study [22][23][24][25][26] . In another study, it has been reported that the use of cinnamic aldehyde or carvacrol (200 mg/kg diet) does not affect dry matter consumption, live weight gain, and feed conversion ratio parameters [27] .…”

Kafkas Univ Vet Fak Derg, 26 (1): 59-64, 2020. AbstractThe purpose of this study is to investigate the effect of oregano oil (Origanum vulgare) at on fattening performance and blood oxidantantioxidant balance such as glutathione (GSH), superoxide dismutase (SOD) and glutathione peroxidase (GPx) catalase (CAT) enzyme activities, malondialdehyde, ceruloplasmin, nitric oxide, albumin, total protein and globulin in post-weaned Tuj breed lambs. The lambs were average 155 days old, and were divided into 3 groups regardless of gender, and in total 18 lambs were used. In the study the control group (C) was fed with basal ration; while the experimental groups were orally fed with oregano oil supplementation as a commercial product in daily doses of 1 mL/lamb/day (T1) and 2 mL/lamb/day (T2), respectively, in addition to the basal ration, via sterile injections. The experiment was maintained for a total of 52 days of which 10 days were adaptation period. In the study, it has been seen in post-weaned Tuj breed lambs that using different doses of oregano oil had no effect on live weight gain, daily live weight gain, daily feed consumption, and feed conversion ratio (P>0.05). In the study, it was determined that the addition of oregano oil to the ration made no significant difference on fattening performance and MDA, GSH, CAT, ceruloplasmin, nitric oxide, albumin, total protein and globulin values of blood oxidant-antioxidant parameters. SOD and GPx values were significantly affected by the addition of oregano oil to the lamb rations at the point of examining the effect on blood oxidant-antioxidant balance (P<0.05). As a result, it has been determined that oregano oil did not affect the performance parameters, it significantly affected the oxidant-antioxidant balance in lambs.

Kuzular ortalama 155 günlük yaşta olup cinsiyet gözetilmeksizin 3 gruba ayrılmış ve toplamda 18 kuzu kullanılmıştır. Çalışmada kontrol grubu (K) bazal rasyonla beslenirken deneme gruplarına bazal rasyona ek olarak sırasıyla 1 mL/kuzu/gün (T1) ve 2 mL/kuzu/gün (T2) dozlarında ticari ürün olan kekik yağı ilavesi steril şırıngalar ile hayvanlara günlük olarak oral şekilde verilmiştir. Deneme, 10 gün adaptasyon dönemi olmak üzere toplam 52 gün sürdürülmüştür. Çalışmada kesilmiş Tuj ırkı kuzularda kekik yağının farklı dozlarda kullanımının canlı ağırlık artışı, günlük canlı ağırlık artışı, günlük yem tüketimi ve yemden yararlanma oranını etkilemediği görülmüştür (P>0.05).

The use of essential oils as a growth promoter for small ruminants: a systematic review and meta-analysis

Background: Due to their antimicrobial properties and safety, essential oils are currently proposed as a sustainable option for antibiotic alternatives in the livestock sector. This current systematic review and meta-analysis investigated the effects of dietary essential oil supplements on dry matter intake (DMI), average daily gain (ADG), and feed conversion ratio (FCR) of small ruminants. Methods: A total of 12 studies (338 small ruminants) were included in this meta-analysis. The overall effect size was quantified using Hedges’ g with 95% confidence interval (CI) using a fixed-effect model. Publication bias was inspected using Begg’s and Egger’s tests, followed by trim and fill method to detect the number of potential missing studies. Results: Insignificant heterogeneity among studies was detected both on DMI (P of Q = 0.810; I-square = 0.00%), ADG (P of Q = 0.286; I-square = 17.61%), and FCR (P of Q = 0.650; I-square = 0.00%). The overall effect size showed that essential oils supplementation had no significant impact on DMI (Hedges’ g = -0.12; 95% CI = -0.50 to 0.26; P = 0.429) and FCR (Hedges’ g = -0.17; 95% CI = -0.55 to 0.22; P = 0.284), but had a significant positive impact on ADG (Hedges’ g = 0.44; 95% CI = 0.12 to 0.76; P = 0.002). The result of publication bias analysis showed that DMI, ADG, and FCR did not present any significant biases ( P > 0.10), and no potential missing studies detected. Conclusions: Dietary essential oil could improve ADG of small ruminants, without any alteration on DMI and FCR. Further research in this topic is still required to provide stronger evidence of the potency of essential oil as a growth promoter for small ruminants.

Thymbra spicata has been used traditionally as herbal tea for the treatment of some diseases such as asthma, bronchitis, respiratory, coughs, and sore throat infection in Anatolia. In the current study, the essential oil of T. spicata (EOTS) were investigated for their antimicrobial, anti-biofilm activity and chemical composition. The chemical composition of Thymbra spicata was analyzed by gas chromatography-mass spectrometry (GC-MS). Antimicrobial and anti-biofilm properties were determined using broth microdilution methods. According to the results of the present study, the GC-MS profile highlights that the mains compounds were found grandisol 21.99%, cadinol 6.45%, lavandulol acetate 4.39%. The antibacterial activity of the EOTS was evaluated by the micro-dilution method against multidrug resistant Pseudomonas aeruginosa. EOTS produced inhibitory effects against the tested strains. It inhibited 11 clinical isolates of against P. aeruginosa with Minimum Inhibitory Concentration (MIC) values in the range of 1.56-12.5 μl/mL. Minimum Biofilm Inhibitory Concentration (MBIC) value was found to be range of 3.12-25 (μl/mL) while the Minimum Biofilm Eradication Concentration (MBEC) value was found to be 6.25-25 (μl/mL). MIC value of the EOTS was applied onto the bacterial biofilm formations. It was seen that biofilm metabolism was reduced by 2.0-51.6 %. The findings of this study show that EOTS has antibacterial and anti-biofilm activity against P. aeruginosa isolates. Thus, essential oil of T. spicata may be useful a potential source for the treatment of multidrug resistant P. aeruginosa infections and biofilms.Özet. Thymbra spicata Anadolu'da astım, bronşit, solunum, öksürük ve boğaz ağrısı enfeksiyonu gibi bazı hastalıkların tedavisi için geleneksel olarak bitki çayı olarak kullanılmaktadır. Bu çalışmada, T. spicata esansiyel yağının (EOTS) antimikrobiyal, anti-biyofilm aktivitesi ve kimyasal bileşimi araştırılmıştır. T. spicata' nın kimyasal bileşimi, gaz kromatografisi-kütle spektrometresi (GC-MS) ile analiz edilmiştir. Antimikrobiyal ve anti-biyofilm özellikleri, broth mikro-dilüsyon yöntemleri kullanılarak belirlenmiştir. Bu çalışmanın sonuçlarına göre, GC-MS profili, ana bileşiklerin % 21,99 grandisol,% 6.45 cadinol,% 4.39 lavandulol asetat olduğu görülmektedir. EOTS antibakteriyel aktivitesi, çoklu ilaç dirençli P. aeruginosa'ya karşı mikro-dilüsyon yöntemi ile değerlendirilmiştir. EOTS'un test edilen suşlara karşı inhibitör etkiler ürettiği görülmektedir. Esansiyel yağ, 11 adet P. aeruginosa klinik izolatı, 1.56-12.5 μl / mL aralığında Minimum inhibitör Konsantrasyon (MIC) değerleri ile inhibe etmiştir. Minimum Biyofilm İnhibitör Konsantrasyon (MBIC) değeri 3.12-25 (μl / mL), Minimum Biyofilm Eradikasyon Konsantrasyonu (MBEC) değeri ise 6.25-25 (μl / mL) olarak bulunmuştur. EOTS' nin MIC değeri bakteri biyofilm oluşumlarına uygulanmıştır. Biyofilm metabolizmasının % 2.0-51.6 arasında azaldığı görülmüştür. Bu çalışmanın bulguları, EOTS'un P. aeruginosa
