“…However, many previous reports were suggested that the selenium supplementation had no effect on growth performance Mateo et al, 2007). In this study, growth performance was not improved but Se concentrations in serum and tissues were increased which were generally consistent with previous researches (Kim and Mahan, 2001a, b, c;Tian et al, 2006a, b). Interestingly, improved gain-to-feed ratio was observed when pigs were fed Se yeast B or Se-proteinate compared to Se yeast A.…”

This experiment was conducted to evaluate the bioavailability of different organic selenium (Se) products in finishing pigs. A total of 48 growing pigs, average body weight 47.6 kg±0.05, were allotted to four different treatments in a randomized complete block (RCB) design in three replicates with four pigs per pen. Three different organic Se products, Se-enriched yeast (treatments A and B) and Se-proteinate (treatment C), were used in conjunction with a basal diet with no added Se as a control treatment. In growing period, pigs were fed the same diet but finishing pigs were fed each treatment diet containing organic Se products for 6 weeks. During the experimental period, feed intake and body weight were measured and blood samples were collected to determine the Se concentration. At the end of this experiment, 3 pigs per treatment were killed and various tissues (loin, liver, kidney, pancreas and spleen) were collected to analyze the Se concentration. The body weight, and average daily feed intake (ADFI) were similar among treatments, but the average daily gain (ADG) was increased on Se-proteinate treatment (p<0.01) and gain-to-feed ratio (G/F ratio) was improved on Se yeast B or Se-proteinate treatment (p<0.01). The tissue Se content was also increased when pigs were fed organic Se sources, and Se was retained efficiently in loin (p<0.01) and kidney (p<0.05) when Se yeast B was provided. The serum Se concentration was increased when organic Se was provided and was higher when pigs were fed Se-proteinate (p<0.01); subsequently liver Se was also higher on Se-proteinate treatment than other treatments. The Se yeast A treatment did not show any increment of Se concentration both in serum and tissues. This result demonstrated that Se retention and bioavailability in finishing pigs were varied by Se products although organic sources were provided. Consequently, each organic Se product should be evaluated before it is used as a supplement in animal feed.

“…However, DM, OM and CP intake were influenced by OS supplementation in the present study, which is consistent with the findings of Hemken (1998) who reported a significant increase in the daily DM intake in 0.15 and 0.3 ppm Se-supplemented lactating cows when compared to the unsupplemented cows. On the other hand, Tian et al (2006) showed that pigs fed organic Se had a greater DMI when compared with unsupplemented animals fed during the growing phase, while Payne and Southern (2005) showed no effect for broilers. The selenium concentration of basal diets in Tian et al (2006) study was 0.06 ppm and in Payne and Southern (2005) experiment the selenium concentration of basal diets in starter and grower were 0.12 ppm and in finisher was 0.11 ppm.…”

The aim of this study was to compare the effects of two Se sources on the early lactation of native goats, on nutrient digestibility, as well as nitrogen and energy status of Iranian native goats. Twenty-one native goats aged, approximately 41 ± 9 months and having body weights of 46 ± 8 kg were selected for the experiment. The goats were randomly divided into three groups with an equal number of goats. One group was supplemented with Selemax 2000® as the organic selenium (OS), the second group received diluted sodium selenite as the inorganic selenium, while the third group received no supplementation and served as the control group (C). The results of this research showed that the selenium supplement did not have a significant effect on nutrient digestibility (apart from crude fat) (P > .05) but, the dry matter, organic matter and crude protein intake significantly increased. However, faecal N, urinary N, total N production and energy status were affected by the treatments (P < .05). It can be concluded that OS seems to be a better choice, considering the nitrogen and energy available for metabolism and its partition between milk production and deposit/mobilization within the body.

“…The greatest concentrations were achieved in the kidneys and adrenals in rats when given selenomethionine [38] . In pigs, selenium concentration was generally the highest in the kidney after administration of selenomethionine [39] . However, in the mouse, the liver absorbed the injected selenomethionine more efficiently than did any other tissues, showing the highest selenium concentrations [40] .…”

BackgroundKynurenine aminotransferase 3 (KAT3) catalyzes the transamination of Kynurenine to kynurenic acid, and is identical to cysteine conjugate beta-lyase 2 (CCBL2) and glutamine transaminase L (GTL). GTL was previously purified from the rat liver and considered as a liver type glutamine transaminase. However, because of the substrate overlap and high sequence similarity of KAT3 and KAT1, it was difficult to assay the specific activity of each KAT and to study the enzyme localization in animals.MethodsKAT3 transcript and protein levels as well as enzyme activity in the liver and kidney were analyzed by regular reverse transcription-polymerase chain reaction (RT-PCR), real time RT-PCR, biochemical activity assays combined with a specific inhibition assay, and western blotting using a purified and a highly specific antibody, respectively.ResultsThis study concerns the comparative biochemical characterization and localization of KAT 3 in the mouse. The results showed that KAT3 was present in both liver and kidney of the mouse, but was much more abundant in the kidney than in the liver. The mouse KAT3 is more efficient in transamination of glutamine with indo-3-pyruvate or oxaloacetate as amino group acceptor than the mouse KAT1.ConclusionsMouse KAT3 is a major glutamine transaminase in the kidney although it was named a liver type transaminase.General significanceOur data highlights KAT3 as a key enzyme for studying the nephrotoxic mechanism of some xenobiotics and the formation of chemopreventive compounds in the mouse kidney. This suggests tissue localizations of KAT3/GTL/CCBL2 in other animals may be carefully checked.
