Lasalocid is an ionophore coccidiostatic agent frequently used in poultry. Its extensive use causes the formation of residues in edible tissues and eggs which may pose a risk to consumers. Silybin is the main compound extracted from the herb milk thistle Silybum marianum and its hepatoprotective effect has been reported in literature. The aim of the study was to compare lasalocid and silybin cy...

High value specialty chemicals are usually obtained from natural products by extracting with generally regarded as safe (GRAS) soh•ents. Because organic solvents are quite often used, high operating and disposal costs often occur. When compared to traditional solvents, water can be viewed as an interesting a/tentative because of its low operating and disposal costs. Milk thistle contains compou...

A total of 231 different soil Streptomyces isolates were recovered from 16 different locations in North Jordan. They were assessed for their phytotoxic activity on seeds of cucumber (Cucumis sativus L.) and ryegrass (Lolium perenne L.) placed adjacent to a 2 cm wide Streptomyces culture strips grown at 28C degrees for 3 weeks on starch casein nitrate (SCN) agar. Phytotoxicity was ascertained on...

The spatial arrangement of plants in a landscape influences wind flow, but the extent that differences in the density of conspecifics and the height of surrounding vegetation influence population spread rates of wind dispersed plants is unknown. Wind speeds were measured at the capitulum level in conspecific arrays of different sizes and densities in high and low surrounding vegetation to deter...

Background: This study was conducted to determine the efficacy of milk thistle seeds (MTSs) in counteracting the toxic effects of aflatoxin B1 (AFB1) in a contaminated diet fed to broilers.Methods: Two dietary inclusion rates of AFB1 (0, 0.250 and 500 ppb) and MTS (0, 0.5 and 1%) were tested in a 3×3 factorial manner. The effect of nine experimental treatments was assessed using 216 one-d-old R...

BACKGROUND AND AIM OF THE WORK The authors have previously reported the use of Silymarin (a Silybum marianum standardized extract) as a promoter of milk production in cows. Due to the important psychological impact of hypogalactia in women after delivery, we evaluated the role of Silymarin as a safe and effective galactogogue for human species. METHODS 50 healthy women during lactation were e...

background & aim: aflatoxin (af) is the most important fungus that contaminates food and feed and can enter the food chain of humans. the aim of this study was to investigate the ability of thistle seeds (silybum marianum l.) to reduce the adverse effects of aflatoxin b1 (afb1) on the immune system, variables related to the intestine, appearance and mortality of the broiler chickens. exper...

The response of plant species to future atmospheric carbon dioxide concentrations [CO(2)] has been determined for hundreds of crop and tree species. However, no data are currently available regarding the response of invasive weedy species to past or future atmospheric [CO(2)]. In the current study, the growth of six species which are widely recognized as among the most invasive weeds in the con...
