“…These results are in full agreement with those reported by Hassaan et al (2015) who found that values of body weight and body weight gain were improved significantly (P≤0.01) due to iodine supplementation especially at 4.8 followed by 2.4mg iodine/kg diet compared with control group. Similar to results of the current study, Ibrahim et al (2015) reported that body weight and body weight gain were significantly improved by increasing iodine level at 2.4mg I/kg diet compared with the control diet in Sinai laying hens. Likewise, these results are in agreement with those reported in foreign chicken by El-Ansary et al (1996) who demonstrated that addition of KI to the diet increased (P≤0.05) the body weight and body weight gain of the hens comparing to control group.…”

“…The results showed that iodine treated had significantly (P≤0.01) high Red blood cells (RBC's) number and White blood cells count (WBC's) especially T5 and T4 that fed 4.8 or 2.4mg I/kg diet respectively (Table 4). These results comes in agreement with the previous findings of El-Nagar et al (2001) on broiler chicken, Abaza et al (2003) on Alexandria cockerels, Ibrahim et al (2015) and Hassaan et al (2015) on local chicken, they reported that RBC's number was significantly increased with dietary iodine supplementation from 2.4 to 4.8mg I/kg diet (hyperthyroidism), which was accompanied by a significant increase in hemoglobin and heamatocrite concentration. As well as WBC's count was significantly increased (P≤0.05) in chicken fed diet containing 2.4 or 4.8mg I/kg diet compared with the control 1 group.…”

“…As well as improved significantly (P≤0.05) shell thickness as compared with the hens in the control 2 group. These results agreed with the findings of Soliman et al (2008), Madian (2008), and Ibrahim et al (2015) who reported that external egg quality especially shell thickness and internal egg quality especially albumen and yolk height were significantly improved when they supplementation iodine from 0.48mg to 2.4mg I/kg diet for local chickens. Abdel-Hamid et al (2000) reported that the beneficial effect of dietary CaI2 on external egg quality is due to its role on enhance Ca absorption through the gut, therefore saving more Ca for egg production and external egg quality.…”

“…On the other hand, laying performance parameters (egg number, production% and mass) were significantly improved in the hens fed diet contains 4.8 and 2.4mg CaI2/kg diet respectively compared with those in the control 2 group. These findings are consistent with the findings of El-Ansary et al (1996) Ibrahim et al (2015) in local chickens reported that, addition of 1mg CaI2 or 0.80 mm or 1.2 and 2.4mg I/kg diet respectively improved the feed conversion ratio as well as improved significantly egg number, mass and production% compared with the control group. The influence of iodine on feed utilization may be due to an alteration of the microflora of the gut, consequently, more nutrients are available for better growth performance of chicks (Stanley and Bailey, 1989).…”

“…Additionally, El-Ansary et al (1996) reported that administration of KI in drinking water at level of 400ppm increased (P≤0.05) feed conversion, egg production, weight and mass. Moreover, Ibrahim, et al (2015) found that performance (egg production and egg mass), hatchability percent, feed conversion ratio improved by increasing iodine level up to 2.4mg iodine/kg diet as compared with control diet in Sinai laying hens. They added that dietary iodine supplementation, up to 2.4mg/kg diet improved blood parameters, hematological traits, T3 level, and T3/T4 ratio without negative effects on liver function and immune responses, interms of ALT, AST activity and WBC's count.…”

This experiment was conducted for a complex period of 24 wks (each of 12 wks, respectively) to investigate the effect of adding different dietary levels of iodine as calcium iodide (CaI2) on modulating some productive, reproductive and physiological parameters of Inshas strain (Egyptian developed strain). For this purpose 150 laying hens and 15 males (36 until 48 wks of age) were taken from a large flock in the 2 nd period after finishing the 1 st period (24-36 wks of age) that used in recording the egg production only and then divided into five equal treatment groups, each of 30 females and 3 males, with three equal replicates nearly similar in live body weight. The 1 st group (T1) represented the overall mean of egg production of the flock and fed the basal diet (0.3 mg iodine/kg diet) and served as control 1, the other four groups were having an average egg production less than the overall mean by 20%. Hens were divided as follows, the 2 nd group (T2) was fed the basal diet and served as control 2, while the 3 rd (T3), the 4 th (T4) and the 5 th (T5) groups were fed the basal diet plus 1.2, 2.4 and 4.8 mg iodine/kg diet, respectively. Results indicated that iodine supplementation especially at 4.8 followed by 2.4 mg iodine/kg diet non significantly improved feed conversion ratio (g feed/g egg) and egg mass, while shell thickness was significantly (P≤0.05) improved compared to the control 2 group. Egg number and production percentage were significantly (P≤0.05) improved by iodine supplementation at 4.8 mg iodine/kg diet (T5 group) compared to the control 2 group. Moreover, significant increases were obtained for red and white blood cells count. As well, plasma total protein, albumin, globulin, T3 and T4 hormones, calcium and phosphorus salts and HDL-Ch were elevated significantly (P≤0.05) at 4.8mg iodine/kg diet. Conversely, additional iodine especially (T5 group) reduced significantly plasma concentration of total lipid, cholesterol, LDL-Ch. On the other hand, T4 and T5 groups recorded the highest values of fertility and hatchability percentage of Inshas hens. In conclusion, dietary addition of iodine as CaI2 is a practical application at 4.8mg I/kg diet to Inshas hens and had beneficial effects on productive, reproductive, physiological and hematological parameters and immune status.

A total number of 330 Bandarah chicken (300 females and 30 males) 40wks-old, were randomly distributed equally into six experimental groups to investigate the effect of supplementing iodine sources (organic and inorganic) with different metabolizable energy levels in 2×3 factorial design on productive, reproductive and immunological traits during the laying period (40-56 wks of age). Laying hens were fed three different metabolizable energy levels being 2606, 2705 and 2803 kcal/kg diet with 0.5 mg iodine from two sources, organic (iodine enriched yeast) and inorganic (Ca (IO3)2•H2O). Results obtained could be summarized as follow: Chickens fed diet containing 2705 kcal of ME /Kg diet and supplemented with organic iodine recorded significantly the highest laying rate and egg mass and the best feed conversation ratio compared with the other experimental groups. The highest ratio of triiodothyronine to thyroxin were recorded for the groups fed diet containing 2606 or 2705 kcal of ME /Kg diet and supplied with organic iodine compared with the other experimental groups. The group fed diet contained 2606 kcal of ME /Kg diet and supplied with organic iodine had significantly an increase in plasma high density lipoprotein and high density lipoprotein to low density lipoprotein ratio compared with the other experimental groups. Results displayed that there was a significant increase in serum total antioxidant capacity when hens fed diet contained 2606 kcal of ME /Kg diet compared with those fed 2705 or 2803 kcal of ME /Kg diet supplemented with both of iodine sources. Feeding laying hen diet containing 2606 kcal of ME /Kg diet supplied with organic iodine showed significantly the highest Immunoglobulin G value compared with the others. It could be concluded that the supplementing diets containing 2705 or 2606 kcal of ME /Kg diet with 0.5 mg iodine enriched yeast/Kg diet is the most successful supplement for enhancing productive, hatchability, immunity, antioxidant status, as well as economical efficiency for Bandarah laying hens.

The objective of the present experiment was to examine the effect of lighting regimens, iodine sources and levels and their interactions on productive performance, hatching traits, some biochemical blood parameters and thyroid hormones of Mandarah chickens. A total of 400 Mandarah chicks at 8 weeks of age were housed in closed system house and divided randomly into two equal groups (200 chicks / group). Chicks of the first group were exposed toStep-Up Photoperiod (SUP): The photoperiod was increased gradually from 10 h/d at 8 wks of age by half an hour each wk to reach 16 h/d at 20 wk of age (Lr1), Chicks of the second group were exposed to Constant-Step Up Photoperiod (C-SUP): The photoperiod was kept constant at 12 h/d at 8 weeks of age until 16 wk of age and increased gradually by an hour each wk to reach 16 h/d at 20 wk of age (Lr2). The chicks within each lighting regimen were divided equally into four dietary supplementations groups (5 replicates of 10 birds each) as follows: basal diet supplemented with 0 .5 mg Potassium iodide (control, T1), 2 mg Potassium iodide (T2), 0 .5 mg Iodide-enriched yeast (T3) and 2 mg Iodide-enriched yeast (T4) / Kg diet. The results during the laying period up to 36 wk have shown that exposing Mandarah chickens to Lr1 regimen significantly improved egg weight, egg production (%) , egg mass , feed conversion ratio, fertility (%), hatchability (%),body weight at hatch, yolk sac and fabricious gland (%) compared to Lr2 regimen. Moreover, plasma IgM, IgG, TAC, HDL, HDL/LDL ratio and T4 significantly increased for Lr1 compared with Lr2. Feeding Mandarah chickens on 2mg organic iodine/kg diet significantly improved the laying performance , feed conversion ratio, plasma IgM, HDL, HDL/LDL, T3/T4, L%, H%, H/L ratio compared with inorganic iodine either o.5 or 2 mg /kg diet. Also, the interaction of Lr1˟ organic iodine ˟ 2 represented highest (p<0.05) values of egg production%,egg mass,plasma IgM, HDL,HDL/LDL,T3/T4 ratio and L (%), Besides improvement of feed conversion compared with other interactions. In conclusion, it is possible to use the SUP regimen combined with feeding on 2 mg organic iodine /kg diet in laying management from 8-36 weeks of age to improve productive and reproductive performance, hatching traits, hatched chicks body weight and immunity system of Mandarah chickens.
