Introduction of biologically active supplements to the diet poultry results in maximal use nutrients and positively influences live weight slaughter parameters. This promotes rational economical fodders boosts productivity. We studied a mineral feed supplement – an organic selenium compound, which has much greater bioavailability than inorganic sources selenium. Selenomethionine is easily diges...

The problem of selenium poisoning in farm animals has excited interest both from an academic and practical point of view. However, since the pioneering work of K. W. Franke and his coworkers, and the discovery of selenium in toxic grains by Robinson,’ relatively less attention has been paid to the mode of action of selenium compounds or means of detoxification. At an early date Hofmeister (1) r...

Two experiments were conducted to determine the effect of varying dietary selenium (Se) levels and Se source on growing swine. In Exp. 1, seleniferous wheat and oats were used to formulate diets containing .47, 2.58, 5.60 or 8.40 micrograms/g organic Se. Dietary Se level had no effect on pig performance during the 6-wk experiment as measured by daily gain, daily feed intake or feed/gain. Blood ...

Understanding the structural and compositional origins of midgap states in semiconductor nanocrystals is a longstanding challenge in nanoscience. Here, we report a broad variety of reagents useful for photochemical reduction of colloidal CdSe quantum dots, and we establish that these reactions proceed via a dark surface prereduction step prior to photoexcitation. Mechanistic studies relying on ...

Selenium (Se), an essential micronutrient, is believed to enhance neutrophil functions. This study aimed to compare the effects of supplemented organic (Sel-Plex®) and inorganic (sodium selenite) Se on neutrophil functions in high-producing dairy cows, during the periparturient period. Twenty-five Holstein cows were randomly allocated to five dietary treatments as follows: control diet (basal d...

Abstract Liquid chromatography‐tandem mass spectrometry (LC‐MS/MS) was used for the rapid quantification of multiple mycotoxins, specifically aflatoxins B 1 , 2 G and (AFB AFB AFG ), ochratoxin A (OTA), deoxynivalenol (DON), zearalenone (ZEN), in walnuts, pistachios, peanuts, coffee beans, rice, chickpeas from various countries. Total counts fungi, Aspergillus flavus, parasiticus were also asse...

an experiment was carried out to compare the effects of laying hen’s diet supplemented with inorganic and different organic sources of selenium (se) on quality and oxidative stability of eggs during storage. a total of 81, (35-week old) laying hens of lohmann lsl-white were assigned to cages in a completely randomized design with 9 groups of treatment and 3 replicates of 3 birds. hens in each g...

The ability of some crops to accumulate selenium (Se) is crucial for human nutrition and health. Selenium has been identified as a cofactor of the enzyme glutathione peroxidase, which is a catalyzer in the reduction of peroxides that can damage cells and tissues, and can act as an antioxidant. Plants are the first link in the food chain, which ends with humans. Increasing the Se quantity in pla...

Organic superconductors part of a generic phase diagram The Copenhagen group led by Klaus Bechgaard and experienced with the chemistry of selenium succeeded in the synthesis of a new series of conducting salts all based on the TMTSF molecule namely, (TMTSF)2X where X is an inorganic mono-anion with various possible symmetry, spherical (PF6, AsF6, SbF6, TaF6), tetrahedral (BF4, ClO4, ReO4) or tr...
