Effect of iodine sources and dietary energy levels on productive, physiological and immunological performance of Bandarah laying hens
Articles in Press, Accepted Manuscript, Available Online from 19 May 2025
A total number of 330 Bandarah chicken (300 females and 30 males) 40-wks-old, were randomly distributed equally into six experimental groups to investigate the effect of supplementation iodine sources (organic and mineral) with different metabolizable energy in 2×3 factorial design on productive, reproductive and immunological traits during the laying period (40-56 wks of age). Laying hens fed three different metabolizable energy levels with 0.5 mg iodine from two sources; organic source (iodine enriched yeast) and inorganic source (Ca (IO3)2∙H2O) and the metabolizable energy levels were 2600, 2700 and 2800 kcal of ME /Kg diet. Results obtained could be summarized as follow: 1- Chickens fed diet containing 2700 kcal of ME /Kg diet and supplanted with organic iodine recorded the significant highest laying rate and egg mass and the best feed conversation ratio compared with the other experimental groups. 2- The best record of number hatched per hen was occurred by the groups fed diet received either 2700 or 2600 Kcal of ME/kg diet with Org-I diet. 3- The highest ratio of triiodothyronine to thyroxin were recorded for the groups fed diet containing 2600 or 2700 kcal of ME /Kg diet and supplied with organic iodine compared with the other experimental groups. 4- The group fed diet contained 2600 kcal of ME /Kg diet and supplied with organic iodine had significantly increase in plasma high density lipoprotein and high density lipoprotein to low density lipoprotein ratio compared with the other experimental groups. It could be concluded that the supplementation of the dietary containing 2700 or 2600 kcal of ME /Kg diet with 0.5 mg iodine enriched yeast/Kg diet is the most successful supplement for enhanced productive, hatchability, immunity, antioxidant status, and therefore economic efficiency for Bandarah laying hens.
