1. The effect of feeding inorganic and organic selenium sources on the hematological blood parameters, reproduction and health of dairy cows in the transition period
ABSTRACT. The purpose of this study was to investigate the effects of four types of diets containing different forms of selenium on the hematological blood parameters, reproduction and health of dairy cattle during the transition period. Twenty-four close-up dry cows with a mean of 259 ± 1days of pregnancy and expected 21 ± 1days prior to parturition were

2. The effect of feeding inorganic and organic selenium sources on the performance and content of selenium in milk of transition dairy cows
ABSTRACT. The aim of this study was to determine the effects of supplementing close-up and fresh dairy cows’ diets with sodium selenite or organic sources of selenium (Se) on the dry matter intake (DMI), milk production and composition. Based on their body condition score (BCS), previous lactation milk yield and expected calving date, 24 multiparous Holste

3. Radioprotective Effect of Sodium Selenite on Mandible of Irradiated Rats
Resumo O propósito deste estudo foi testar o efeito radioprotetor do selênio na microarquitetura óssea de mandíbulas de ratos irradiados. Quarenta ratos foram separados em 4 grupos com 10 animais: grupo controle (GC), grupo irradiado (GI), grupo selenito de sódio (SSG) e grupo selenito de sódio irradiado (SSIG). Uma dose única de 0,8 mg/kg de selenito

4. Effects of different sources of selenium supplementation on antioxidant indices, biochemical parameters, thyroid hormones and Se status in transition cows
ABSTRACT. The aim of this study was to determine the effects of supplementing close-up and fresh dairy cows’ diets with sodium selenite or organic sources of selenium (Se) on the serum biochemical parameters and antioxidant indicators and Se status. Twenty-four multiparous Holstein dairy cows were balanced by body condition score (BCS), previous lactation

5. Organic selenium supplementation is cost-effective for increasing the number of seminal doses produced by sexually mature boars
ABSTRACT The present experiment was carried out to evaluate the economic viability of supplementing boar diets with organic selenium aiming to increase the number of seminal doses of sexually mature boars. Twelve boars were divided into three groups: control group received 0.3 mg kg−1 Se from sodium selenite (n = 4), inorganic group received 0.5 mg kg−1

6. Vitamin E and Sodium Selenite Against Mercuric Chloride-Induced Lung Toxicity in the Rats
The aim of the present study was to elucidate the possible protective role of vitamin E and / or sodium selenite on mercuric chloride-induced oxidative stress and histopathological changes in the lung tissue of the rats. Adult male albino Wistar rats were exposed to mercuric chloride (1.0 mg/kg day) for four weeks. Treatment with mercuric chloride led to oxi

7. Protective Effects of Sodium Selenite and Vitamin E on Mercuric Chloride-Induced Cardiotoxicity in Male Rats
This study was designed to investigate the protective effects of sodium selenite and/or vitamin E against mercuric chloride-induced cardiotoxicity. Male Wistar rats (n=48, 310±10 g) were administered mercuric chloride (1.0 mg/kg bw), sodium selenite (0.25 mg/kg bw), vitamin E (100 mg/kg bw), sodium selenite plus mercuric chloride, vitamin E plus mercuric ch

8. Lead Nitrate Induced Testicular Toxicity in Diabetic and Non-Diabetic Rats: Protective Role of Sodium Selenite
Among heavy met als, lead is one of the common pollutants found in the environment and biological system. In the present study, streptozotocin-induced diabetic and normal non-diabetic male Wistar rats were given sodium selenite (1.0 mg/kg bw), lead nitrate (22.5 mg/kg bw) and sodium selenite plus lead nitrate (1.0 mg/kg+22.5 mg/kg bw, respectively) through g

9. Radioprotective Effect of Sodium Selenite on Developing Teeth
Agentes radioprotetores, como o selênio, são utilizados para reduzir os danos causados pela radiação nos tecidos sadios. O objetivo nesse estudo foi avaliar o efeito do selenito de sódio no desenvolvimento de molares de filhotes de ratas irradiadas. Vinte ratas grávidas foram aleatoriamente divididas em 4 grupos: controle, irradiado, selênio e selêni

10. Copper and selenium supplementation in the diet of Brangus steers on the nutritional characteristics of meat
Twenty-eight Brangus cattle were used to determine the effect of copper and selenium supplementation on the carcass characteristics, fatty acid composition of the longissimus dorsi muscle and on the copper and selenium concentrations in the liver. The treatments were: no supplementation of copper or selenium; 2 mg Se/kg DM as sodium selenite; 40 mg Cu/kg DM

11. Radioprotective effect of sodium selenite on bone repair in the tibia of ovariectomized rats
Esse estudo avaliou a proteção do selênio no processo de reparação óssea em ratas ovariectomizadas após irradiação. Para isso, 80 ratas Wistar foram divididas aleatoriamente em 4 grupos experimentais: ovariectomizado, ovariectomizado/selênio, ovariectomizado/irradiado e ovariectomizado/selênio/irradiado. Foi realizado um defeito ósseo na tíbia d

12. EFEITO DO COBRE E DO SELENITO DE SÓDIO NO ESTRESSE OXIDATIVO, PROTEÍNAS SÉRICAS E CARGA PARASITÁRIA DE CORDEIROS INFECTADOS EXPERIMENTALMENTE POR Haemonchus contortus / EFFECT OF COPPER AND OF SODIUM SELENITE ON OXIDATIVE STRESS, SERUM PROTEINS AND PARASITIC LOAD IN LAMBS EXPERIMENTALLY INFECTED WITH Haemonchus contortus
O presente trabalho teve como objetivo avaliar o perfil oxidativo e de proteínas séricas de cordeiros experimentalmente infectados com Haemonchus contortus e suplementados com selênio e cobre. Foram utilizados 28 cordeiros mestiços Corriedale e Texel, alocados em quatro grupos experimentais com sete animais cada: G1-animais infectados; G2-infectados e su
