Comparison of Bioactive Compound Content in Egg Yolk Oil Extracted from Eggs Obtained from Different Laying Hen Housing Systems
Egg yolk oil is a natural source of bioactive compounds such as unsaturated fatty acids, oil soluble vitamins, pigments and others. Bioactive compound content in egg yolk oil depends from its content in eggs, from which oil was extracted. Many studies show that bioactive compound content in egg is correlated to the content of these compounds in hen feed, but there is also an opinion that hen ho...
متن کاملIodine content in consumer hen eggs
This paper presents the latest information about the supply of iodine to meet its requirements in hens of laying type, on the basis of iodine content in egg yolk and about the importance of eggs as an iodine source in human nutrition. The Sandell-Kolthoff method was applied to determine iodine content in the yolk of eggs from 9 large flocks (54 eggs) and 16 small flocks (96 eggs) in 2004, and f...
متن کاملEffects of incubator humidity and hen age on yolk composition in broiler hatching eggs from young breeders.
The effects of broiler breeder age (26, 28, and 30 wk) and incubator relative humidity (43, 53, and 63% RH) on yolk sac weight and composition in broiler hatching eggs between 16 and 19 d of incubation were evaluated. Percentage yolk sac weight was reduced in eggs from the youngest (26 wk) breeder hens and in eggs incubated at 53% RH. Percentage yolk moisture, in eggs from the youngest hens, wa...
متن کاملHen welfare in different housing systems.
Egg production systems have become subject to heightened levels of scrutiny. Multiple factors such as disease, skeletal and foot health, pest and parasite load, behavior, stress, affective states, nutrition, and genetics influence the level of welfare hens experience. Although the need to evaluate the influence of these factors on welfare is recognized, research is still in the early stages. We...
متن کاملInfluences of Different Sources of Natural Pigments on the Color and Quality of Eggs from Hens Fed a Wheat-Based Diet
This experiment was conducted to evaluate effects of different sources of natural pigments on yolk color and laying hen performance. A completely randomized design with six treatments and six replicates was used.The six experimental treatments were: a control diet containing yellow corn grain, a reference diet containing wheat and barley grain instead of corn; a red pepper diet composed of refe...
