Present study was conducted to investigate the effect of organic selenium and vitamin E on physico-chemical characteristics of broiler meat. This study was a 3 x 2 factorial arrangement of three levels of organic selenium (0, 0.1, and 0.2 ppm) and two levels of vitamin-E (0 and 300mg/kg). Day-old Vencobb broiler chicks (n=180), were randomly assigned in 6 treatment groups. The experiment lasted...

BACKGROUND The New Zealand population has both marginal selenium status and mild iodine deficiency. Adequate intakes of iodine and selenium are required for optimal thyroid function. OBJECTIVE The aim of the study was to determine whether low selenium and iodine status compromises thyroid function in an older New Zealand population. DESIGN We investigated the effects of selenium and iodine ...

To the Editor: We read with interest the article by Inoko et al about selenium deficiency,1 but we do not agree with the interpretation of the data. Selenium deficiency was identified as a factor in the etiology of heart failure syndromes in areas of very low selenium intakes, such as China, where an endemic selenium-responsive cardiomyopathy is called Keshan disease.2 Similar cases of cardiomy...

The aim of this study was to evaluate the effect of organic selenium supplementation on the immune response of broilers vaccinated against coccidiosis, Infection Bursal Disease Virus (IBDV) and Newcastle Diseases Virus (NDV). The study included three treatments (T), T1= control (inclusion of inorganic selenium in a basal diet), T2= basal diet + 0.2 ppm of organic selenium as selenomethionine an...

BACKGROUND Selenium status is inversely associated with the incidence of prostate cancer. However, supplementation trials have not indicated a benefit of selenium supplementation in reducing cancer risk. Polymorphisms in the gene encoding selenoprotein 15 (SELENOF) are associated with cancer incidence/mortality and present disproportionately in African Americans. Relationships among the genotyp...

The aim of the present study was to test the hypothesis that nano- seleniuminclusion in broilers’ diets can improve productivity and metabolic functions of broilers.Feed and water were provided ad libitum. A total of 180 one-day old male Ross 308 chicks were randomly assigned to six groups based on a completely randomized design, each with three replicates of 10 birds. One of the groups served ...

1. The effects of selenium and vitamin E supplementation of the maternal diet on their transfer to the egg yolk and tissues of the newly hatched chick and on the development of the antioxidant system in the chick liver in early postnatal life were investigated. 2. One hundred Cobb broiler breeder hens were divided into 10 equal groups and housed in pens at 25 weeks of age. Each hen received 1 o...

The objective of this study was to evaluate the reproductive toxicity of gossypol and the possible counteracting effect of selenium supplementation in rams. Twenty-five mature crossbred (Barki × Rahamni) rams were randomly divided into 5 equal groups. The first group served as a control (no gossypol in diet). The second and third groups received diets containing free gossypol of 9 and 14 mg·kg(...

The essential trace element selenium, which is a crucial cofactor in the most important endogenous antioxidative systems of the human body, is attracting more and more the attention of both laypersons and expert groups. The interest of oncologists mainly focuses in the following clinical aspects: radioprotection of normal tissues, radiosensitizing in malignant tumors, antiedematous effect, prog...

Selenium is an essential trace element for humans, playing an important role in various major metabolic pathways. Selenium helps to protect the body from the poisonous effects of heavy metals and other harmful substances. Medical studies have provided evidence of selenium supplementation in preventing certain cancers. Low and too high selenium (Se) status correlates with increased risk of e.g. ...
