Selenium in Poultry Nutrition: from Sodium Selenite to Organic Selenium Sources
- Medicine, ChemistryThe journal of poultry science
Advantages and disadvantages of main organic Se sources for poultry (Se-yeast, SeMet, and OH-SeMet) are analyzed, and future directions for the development of new Se sources are identified.
Selenium in poultry nutrition: a review
The present research focuses on the effects of Se on meat and egg quality, antioxidant activity of Se, effects on fatty acid levels, activity of glutathione-peroxidase, or the effect ofSe on the immune system.
Selenium in Pig Nutrition and Reproduction: Boars and Semen Quality—A Review
- Biology, MedicineAsian-Australasian journal of animal sciences
Organic selenium in the form of selenomethionine provided by a range of products, including Se-Yeast and SeMet preparations is an important source of Se to better meet the needs of modern pig genotypes in commercial conditions of intensive pig production.
Revisiting Oxidative Stress and the Use of Organic Selenium in Dairy Cow Nutrition
- Biology, MedicineAnimals : an open access journal from MDPI
It has been proposed that one of the main advantages of organic Se in pig and poultry nutrition is the non-specific incorporation of SeMet into general body proteins, thus forming an endogenous Se reserve that can be utilized during periods of stress for additional synthesis of selenoproteins.
Effects of Dietary Selenium Sources on Physiological Status of Laying Hens and Production of Selenium-Enriched Eggs
- MedicineFrontiers in Nutrition
Results revealed that dietary supplementation of 2 mg/kg of Se increased egg weight, decreased feed conversion ratio, and enhanced the antioxidant capacity of eggs in laying hens relative to the control group, whereas no significant differences were observed among SS, SEY, and SEIP treatment groups for the same.
Nutritional modulation of the antioxidant capacities in poultry: the case of selenium.
- MedicinePoultry science
Analysis of the current data on selenium roles in antioxidant defenses in poultry clearly showed its modulatory effect at the level of breeders, developing embryos, newly hatched chicks, and postnatal chickens, and a search for most effective dietary form of organic Se is a priority in poultry nutrition.
Selenium in Livestock and Other Domestic Animals
Recent developments in selenoprotein studies and the new roles of Se in antioxidant defenses and cell signaling have opened new areas of Se research, which have aided understanding of the application of this element to the livestock industry.
Effect of Microbiota-Selenoprotein on Meat Selenium Content and Meat Quality of Broiler Chickens
- Medicine, ChemistryAnimals : an open access journal from MDPI
Bacterial selenoprotein is more efficient than sodium selenite in increasing the breast meat Se deposition and oxidative capacity of broiler chickens, therefore, it can be effectively used to produce Se-rich meat as a functional food.
The effects of selenium feed supplements on the oxidative stability indicators of egg yolk during the laying period
- Acta Veterinaria Brno
The aim of this study was to assess the effects of four types of selenium (Se) feed supplements on the indicators of the oxidative stability of egg yolk. A total of 1,740 Bovans Brown laying hens…
