Comparison of Different Selenium Sources and Vitamin E in Laying Hen Diet and Their Influences on Egg Selenium and Cholesterol Content, Quality and Oxidative Stability
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...
متن کاملComparing responses to different selenium sources and dosages in laying hens.
Developing new sources of organic Se has potential benefit for animal production and human nutrition via animal-based foods enriched in Se. The objectives of this trial were to compare L-selenomethionine with another organic Se source, Se-enriched yeast (SelPlex 2300), and sodium selenite, an inorganic Se source, against a commercial control diet. The effect of source and the dosage of Se suppl...
متن کاملThe effect of dietary selenium source and level on the uptake of selenium by developing chick embryos.
We studied the effect of dietary source (organic or inorganic) and level of Se on the Se uptake of chick embryos. After receiving a low-Se diet for 16 wk, 126 Leghorn laying hens were randomly assigned to one of seven dietary treatments. Treatments consisted of feeding a low-Se basal diet alone or with one of three levels of added Se (0.1,0.2, or 0.3 mg/kg Se) supplied by sodium selenite or Se-...
متن کاملEffect of dietary iodine on production of iodine enriched eggs
AIM Objective of this study was to investigate the effect of different levels of iodine supplementation on iodine content of eggs in laying hens. MATERIALS AND METHODS In the experiment, 135 laying hens (White Leghorn) of 55 weeks age were randomly distributed to 5 dietary treatments; each group contained 27 laying hens distributed in three replicates of 9 birds each. Diet T1 was control basa...
متن کاملInfluence of dietary vitamin C and selenium, alone and in combination, on the performance of laying hens and quality of eggs
Two hundred and forty laying hens were fed diets supplemented with vitamin C and selenium (Se). Vitamin C was added at 0 or 200 mg/kg, and Se was added as sodium selenite or selenized yeast at 0.3 mg/kg. The feed intake and egg production were measured, and egg quality parameters were determined. Supplementation of the basal diet with Se significantly increased the laying performance; however, ...
