Ascaris suum is one of the most prevalent nematode parasites in pigs and causes significant economic losses, and also serves as a good model for A. lumbricoides, the large roundworm of humans that is ubiquitous in developing countries and causes malnutrition, stunted growth and compromises immunity to other pathogens. New treatment options for Ascaris infections are urgently needed, to reduce r...

The objective of this study was to determine the effect of irradiation of pomegranate seed (PS) on chemical composition, digestibility and kinetic of gas production. Pomegranate seeds were exposed to gamma ray (GR) and electron beam (EB) at doses of 5, 10, 15 and 20 kGy. Three ruminally fistulated rams were used for obtaining ruminal fluid for in vitro digestibility and gas production measuremen...

Antioxidant activities of different vegetables Bitter gourd, Tomato and Spinach (Momordica charantia, Lycopersicon esculentum, Spinacia oleracea) were determined. In addition, rapid visual estimation of tannin content, total phenolic, tested for their free radical scavenging activity (FRSA) in the DPPH (1, 1-dephenyl2-picrylhydrazil radical) of those samples were assessed. A new technique was u...

Collagen powder hydrolysates were reacted with a solution of commercial mimosa bark tannin extract. The mixture was prepared at ambient temperature and 80°C to determine what reactions, if any, did occur between the collagen protein through its amino acids polyphenolic condensed tannin. reaction products obtained analyzed by matrix assisted laser desorption ionization time-of-flight (MALDI ToF)...

The microbiota affects host health, and dysbiosis is involved in colitis. Sorghum bran influences butyrate concentrations during dextran sodium sulfate (DSS) colitis, suggesting microbiota changes. We aimed to characterize the microbiota during colitis, and ascertain if polyphenol-rich sorghum bran diets mitigate these effects. Rats (n = 80) were fed diets containing 6% fiber from cellulose, or...

Plant polyphenolics are receiving increased attention for their influences on belowground processes. Tannins are of particular interest because of their predominance in natural systems, their wide variation in both quality and quantity, and their protein-binding abilities. Current theory holds that simple phenolics increase microbial activity by acting as carbon substrates, while larger tannins...

this experiment was carried out to investigate the effect of adaptation period to oak leave's tannin on rumen ph and ammonia, rumen microbial population, gas production and dry matter true digestibility (ivtdmd) in alamout goat’s rumen (with no previous history of oak leaf consumption) compared with markhoz goat (with previous history of oak leaf consumption). the goats were fed either oak...

The effects of polysaccharides and tannins present in the hulls of field beans (Vicia faba L.) on the digestion of amino acids, starch and lipid were studied in poultry. A control diet without hulls and the same diet substituted with 400 g hulls/kg diet from three different varieties of beans were fed to 3-week-old chicks for 4 d. Digestibility coefficients for amino acids, starch and lipid wer...

A series of previous studies with quebracho tannin (QT) had shown that the tannin was effective at reducing the worm burden of temperate sheep infected with Haemonchus and Trichostrongylus. The potential of using tanniniferous browse plants available in the tropics as a means to reduce or control nematode infections of small ruminants was, therefore, investigated. Leaves of different browse tre...

Abstract In the present study, tannins from stem and root barks of Tessmannia burttii Harms ( Caesalpiniaceae ), a plant species abundantly growing in Tanzania other parts Africa, were investigated for their suitability hides tanning. Tannin powder was extracted at selected temperatures (30, 50 80 °C) influence each temperature on crosslinking capacity evaluated. The interaction mechanism betwe...
