“…Indeed, in order to increase absorption of water, plants in water deficit conditions often reduce their biomass production and contribution more biomass to roots (Albouchi et al 2003). Our results are in agreement with other reports which confirm the effect of irrigation on growth of medicinal and aromatic plants such as Lippia berlandieri (Vazquez and Dunford 2005), Hypericum brasiliense (zobayed et al 2007), Thymus transcapicus (Tabrizi et al 2011) and Thymus daenansis (Bahreininejad 2013).…”

In order to evaluate the effect of irrigation intervals and cattle manure levels on morphological traits, essential oil content and yield of oregano, an experiment was conducted at the experimental Farm of the Faculty of Agriculture, Urmia University, Iran. The experimental design was split-plots, arranged in randomized complete blocks with three replications. Main plots including irrigation intervals (1, 2 and 3 weeks) and four levels of cattle manure at 0, 10, 20 and 30 t ha -1 were allocated to sub plots. Our resultsshowed that increasing irrigation intervals reduced values of all morphological traits except for proportion of stems. Also, values for stems number, plant spread, stem diameter, leaf area, fresh and dry herb yield increased by increasing cattle manure levels. On the other hand, morphological traits not influenced by interaction of treatments except for plant spread and leaf area. The highest essential oil content (2.07%) and yield (66.62 kg ha -1 ) obtained in highest irrigation intervals and cattle manure levels. Whereas, 1 week irrigation interval without use of cattle manure produce lowest essential oil content (1.55%). For essential oil yield, the lowest value (46.37 kg ha -1 ) was found in 2 weeks irrigation interval with application of 20 t ha -1 cattle manure.

“…The dried foliage and inflorescences of both Mexican varieties are used as condiments and as treatment for respiratory and digestive diseases (Rivero-Cruz et al, 2011). The main constituents of essential oils from Mexican oregano include carvacrol, thymol, β-myrcene, α-terpinene, γ-terpinene, p-cymene, and ceneol (Vazquez and Dunford, 2005;SilvaVazquez et al, 2017).…”

-The current study was conducted to investigate the effects of Mexican oregano essential oil (MOO) extracts from Lippia berlandieri Schauer (LBS) and Poliomintha longiflora Gray (PLG) on performance, blood profiles, carcass variables, and meat composition of broilers at slaugther. A total of 360 one-day-old Ross broilers were randomly distributed into four dietary treatments with six replicate pens per treatment and 15 birds per pen. The dietary treatments were: a basal diet (control), control + 0.40 g of LBS/kg of feed, control + 0.40 g of PLG/kg, and control + 0.40 g of LBS/kg + 0.40 g of PLG/kg. Results showed that linear, quadratic, and cubic effects of days were significant in the performance variables of broilers. The treatments with LBS and PLG maintained the broiler body weight without increasing feed intake and water intake when compared with the control group. Broilers given LBS+PLG and PLG had increased blood leukocytes, lymphocytes, lowdensity lipoprotein, and hot carcass yields. In meat composition, treatments with PLG and LBS+PLG presented similar breast protein content compared with the control treatment. Supplementation with these two MOO exhibits positive effects on broiler performance, blood profiles, carcass traits, and meat composition. These two MOO may be promising feed supplements as growth promoters and enhancers of meat quality in broiler production.

“…The significant difference in the level of expression of the four active ingredients in wild vs. cultivated O. ehrenberjii is most likely due to environmental factors. A literature search on earlier publications suggests a dearth of research investigating the effect of the environment on the level of expression of different components in essential oils of Origanum species [20,21]. One citation pointed at the effect of water stress on plant growth and Thymol and Carvacrol concentrations in the Mexican Oregano grown under controlled conditions [20,21].…”

Introduction: The role of Origanum ehrenberjii against bacteria that cause enteric diseases is well known. Salmonella and Enterococcus cause high rates of enteric infections around the world. The aim of this study was to extract essential oils from cultivated and naturally growing O. ehrenberjii, compare the chemical profiles of the extracts and estimate their antimicrobial efficacy against enteric pathogens. Methodology: Sixteen compounds were recovered consistently from essential oils extracted from O. ehrenberjii of wild and cultivated origin. The chemical profiles were determined using GC-MS. Safety of the essential oils was determined by observing mortality of chicks after intramuscular administration of the oils. The antimicrobial efficacy of the oils against the enteric pathogens was determined by the KirbyBauer Single Disk Diffusion assay. Results: The levels of thymol, carvacrol, para cymene and γ-terpinene were significantly different in the two oils. A significant difference in in vitro antimicrobial activity of the two oils against Salmonella enterica serovar Typhimurium was observed. Intramuscular administration of the two oils in one day-old chicks resulted in significant differences in mortality of 60% vs. 5% (p < 0.05) for wild and cultivated herbs respectively, reflecting the higher safety of the cultivated herb due to the differences in the levels of certain active ingredients. Conclusions: The chemical profile of essential oil of wild vs. cultivated O. ehrenberjii differ significantly at compound level, suggesting the reason for their significant difference in efficacy against Salmonella enterica serovar Typhimurium, and also significant differences in the toxicity of the two oils.
