Abstract

This study aimed at determining the chemical composition of sage essential oil (SEO) and yarrow essential oil (YEO), and investigate in vitro their impacts on gas production kinetics, ruminal digestibility and fermentation, and rumen methanogenesis at different dosages (0, 250, 500 and 750 mg L-1 for SEO; and 0, 250, 500, 750 and 1000 mg L−1 for YEO). Alpha-pinene and 1,8 cineol were two major constituents of both SEO and YEO. Both SEO and YEO had a linear and quadratic effect on asymptotic gas production (P<0.05). The gas production rate increased linearly with SEO and curve-linearly with YEO dosages (P<0.05). In vitro degradability of dry matter and organic matter decreased only by YEO. The partitioning factor (PF) and the microbial biomass (MB) decreased and increased linearly with YEO and SEO dosages, respectively (P<0.05). Total volatile fatty acids (VFA ) were not affected by SEO, but decreased in a linear and quadratic manner with YEO dosage (P<0.05). The VFA pattern was modified in a linear and quadratic manner by both SEO and YEO (P<0.05). Ammonia concentration increased linearly only with YEO increasing doses. The methane to total gas (TG) ratio decreased quadratically only by SEO with reductions of 6.7, 13 and 4.2% at the doses of 250, 500 and 750 mg L−1, respectively. These results revealed that SEO modifies the rumen fermentation positively towards producing more MB and less methane in the dose range of 0-750 mg L−1, however, YEO adversely affected the rumen fermentation at all the tested doses.

Abstract

The antifungal activities of 14 selected essential oils (at the concentrations of 0.5 %, 5 %, and 30 %) against the yeast Malassezia pachydermatis (18 isolates and one reference strain) were investigated. The isolates of M. pachydermatis were obtained from swabs of external ear canals of healthy dogs using sterile swabs. The determination of the efficacy was based on a modified disc diffusion method (CLSI M44-A2). The best antifungal efficacy (100 %) was shown by clove, cinnamon and oregano at the concentration of 30 %; less significant efficacy was shown at the concentration of 5 % (38 %, 33 % and 5 %, respectively). Satureja inhibited the growth of Malassezia (efficacy of 16 %) only at the concentration of 30 %. Bergamot, lavender, juniper, cedar, sage, tea-tree, grapefruit, pine, chamomile and yarrow essential oils were not able to form inhibition zones as defined in the methodology used (greater or equal to 15 mm) in all concentrations used. Therefore, according to the interpretation criterion, they were considered ineffective. In all cases, the concentration of 0.5 % was not effective against the growth of Malassezia yeasts.

Summary

Introduction: The high concentration of some trace elements in medicinal plants may lowering the value of herbal material, and may cause poisoning effects.

Objective: The aim of this research was to evaluate the content of trace elements in the organs of: sandy everlasting, yarrow and stinging nettle.

Methods: In the soil samples, the grain size composition, pH, the content of carbon and nitrogen were determined. In the plant material and for the soil samples, the total contents of Zn, Cu, Mn, Fe, Pb were assayed. The values of the bioconcentration factor and translocation factor were also calculated.

Results: The concentration of metals in plant tissues followed in order: Fe>Mn>Zn>Pb>Cu>Hg. The studied species of medicinal plants accumulated mainly Zn, Pb and Hg. It was also shown a high Hg mobility and a low Pb mobility which mainly accumulated in the roots.

Conclusions: As our research shows the plants used in phytotherapy, should come from plantations monitored for toxic heavy metals in soil.

Abstract

An influence of various humic-plant feed additives based on some herbs (nettle, chamomile, yarrow, perforatum), lucerne and humic materials on biochemical indices of Lohmann Brown (LB) layers blood plasma was estimated. Hens were housed in deep litter system, 20 birds in a group. Four groups were formed: control (C – standard feeding), and experimental, supplemented with preparations: E-1 herbal-humic, E-2 humic-herbal and E-3 – humic-lucerne. Hens were placed in the pens on the 16th week of life, addition of preparations with standard food mixture started at the 22nd wk and lasted until 66th wk of life. Blood for analyses was collected four times in the following periods: 27, 37, 54 and 65th wk of life. The applied humic-plant preparations to a limited degree affected the values of examined biochemical parameters in serum: total protein (TP), albumins (Albs), glucose (Glu), urea, triacylglycerols (TAG), total cholesterol (TCh), alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP). It is difficult to determine based on these study, which preparation is one the most active biologically, however is seems that humic-lucerne preparation affected the examined blood parameters to the highest degree. The reference values ranges in hens blood serum LB hens were proposed for: TP (43-65 g/l), Albs (15-22 g/l), urea (0.5-1.2 mmol/l), Glu 10-15 mmol/l), TCh (2.2-4.5 mmol/l), TAG (10-24 mmol/l), AST (4-12 U/l), ALT (150-280 mmol/l) and ALP (190-350 U/l).
