On the daily basis food consumed by human does not fulfil the requirement of Se for the body. Se cannot be directly consumed as it is harmful for the human body that’s why scientist are trying to produce Se enriched foods for human consumption. In this way eggs are the best medium through which consumable Se can be provided to the human by fortifying eggs when Se given to the birds in feed.
Different sources of Se supplementation in the diet may affect the egg shell quality, albumin height and selenium concentration in the eggs when given to ISA hi-sex white commercial layer.A total of 240 birds from ISA hi-sex fed with two Se sources and having three levels (0.2, 0.4, 0.6 mg/kg) each i.e. organic Selenium Yeast (SY), inorganic Se as Sodium Selenite (SS) and combination of organic and inorganic sources of selenium (SY+SS) one control were used in present study. Daily egg production, egg weight and weekly feed efficiency was recorded. Egg shell thickness, egg shell weight, albumen height, yolk index and haugh unit were measured every week. Whole egg Se concentration was determined 2nd, 4th and 8th week of the experiment.
Data collected were analyzed through completely randomized design (CRD) under one ANOVA technique (Steel et al. 1997). Means were separated through Duncan’s Multiple Range test (Duncan’s, 1955) with the help of SAS 9.1. The results of the observed study showed that supplementation of organic Se in the layer hen’s diet improved the albumen height (mm), Haugh unit score and yolk index. In this experiment different sources and levels of Se did not show the statistically significant difference in the results of egg production, egg weight, egg shell weight and egg shell thickness. All the sources and levels of Se improved the whole egg Se concentration and the organic Se showed much better results in whole egg Se concentration as compared to other sources of Se.
