Production performance in Joper broodstock can be improved through increased feed energy and vitamin E-selenium supplementation. This study used 400 laying hens Isa Brown aged 35 weeks and 15 Sentul rooster aged 68 weeks. This study used a factorial completely randomized design with 2 factors, namely metabolic energy levels (2,700 and 2,800 kcal/kg) and vitamin E-selenium supplementation doses (0, 25, 50, 75 and 100 ppm) where each treatment used 10 laying hens and repeated 4 times. The dose of selenium is 0.001 ppm/mg vitamin E. The energy level has a very significant effect (P < 0.01) on (feed, protein and energy) intake and HDP. The dose level of vitamin E- selenium in feed had a very significant effect (P < 0.01) on HDP and significant (P < 0.05) on (feed, protein and energy) intake and FCR. The interaction between the two has a very significant effect (P < 0.01) on HDP. The average feed intake 113-115 g/day, protein intake 21.90-22.20 g/day and energy intake 308-317...

Nutrition supplementation in broiler breeder diets are necessary to provide the nutritional requirements for the optimal performance of the broiler breeder flock after significant genetic improvement of production performance. The study aimed to determine the effect of adding vitamin E and organic selenium to the diet of broiler breeder Rose 308 in the productive and reproductive traits. The experimental flock consist of 60 hens and 10 cocks at 41 weeks of age. The birds divided into four groups for treatments application, and each treatment had three replicates (five hens per replication). The first treatment T1 fed a standard diet without addition (control) containing 15% crude protein and metabolic energy 2775 kilocalories / kg of diet, and T2 used a standard diet and 500 mg vitamin E / kg of diet supplementation, and T3 used a standard ration plus 0.5 mg of organic selenium (Availa powder) / kg of diet supplementation, and T4 used a standard diet plus a mixture of vitamin E and organic selenium (Availa powder) in proportions 500 and 0.5 mg, respectively. The results showed a significant superiority of the second treatment over the control treatment and other treatments in egg weight, as well as the T1 and T2 recorded significant high number of eggs, the percentage of egg production and the number of weekly eggs / hen compared with T4 group There were no significant differences among treatments in the characteristics of egg quality, fertility and hatchability.
In this study, effects of using different oil sources (sunflower oil, rapeseed oil and linseed oil), organic and inorganic selenium and vitamin E on laying hens' productivity and blood parameters of 22−30 weeks of age were evaluated. A total of 60 Lohmann Brown laying hens, which were 22 weeks old, were assigned to 6 treatment groups (10 hens per each treatment group) and fed experimental diets for 8 weeks. They were fed diets containing 5% sunflower oil + 0.5 mg Na2SeO3 + 40 mg/kg vit. E (Control group 1), 5 % rapeseed oil + Na2SeO3 0.5 mg + 40 mg/kg vit. E (Control group 2), and linseed oil 5% + Na2SeO3 0.5 mg + vitamin E 40mg/kg (Control group 3). Diet in Experimental group 1 was supplemented with 5% sunflower oil + Alkosel ® R397 0.5 mg + 40 mg/kg vit. E, Experimental group 2-rapeseed oil 5% + Alkosel ® R397 0.5 mg + 40 mg/kg vit. E, and Experimental group 3-linseed oil 5% + Alkosel ® R397 0.5 mg + 40 mg/kg vit. E. Laying hens were kept in similar conditions. They were fed w...
A study was conducted using 162 Bovans laying hens to investigate the impacts of extra dietary vitamin A (0, 8000, 16,000 IU/kg), selenium (0, 0.25, 0.50 mg/kg), and their combinations on the performance, egg quality, and blood biological parameters of laying hens during summer months. Supplemental vitamin A up to 16,000 IU/kg diet significantly (P < 0.05) improved all productive traits studied except feed intake which increased with 8000 IU/kg diet compared with control. Feed intake and feed conversion of hens fed diet supplemented with selenium revealed high statistical (P = 0.001) differences. All egg quality criteria were not significantly (P < 0.05) affected by dietary vitamin A except albumin percentage and Haugh units, since Haugh unit score was gradually increased with increasing vitamin A level. Vitamin A-enriched groups showed significant (P < 0.05 and 0.01) decreases in plasma albumen, total lipids, and total cholesterol in respect to the unsupplemented groups. Compared with unsupplemented groups, total protein, albumin, total lipid, and total cholesterol were increased in selenium-enriched groups. There were no significant impacts of selenium treatments in layer diets on thyroid hormones and liver enzymes studied except alanine transferase (ALT) and thyroxin (T 4), as compared with the control group. Hematological parameters were not affected by vitamin A treatment except PCV% which decreased with vitamin A supplementation. Hemoglobin and lymphocytes were increased with increasing dietary selenium level. In conclusion, the combined supplementary concentrations of vitamin A (16,000 IU/kg) and selenium (0.25 mg/kg) might be needed for better production and health of laying hens reared under heat stress conditions.

The aim of this study was to determine the effects of different vitamin-E and organic selenium (selenomethionine) levels on performance and immune response of laying hens. A total of 270 laying hens (65-weeks old Lohman-LSL Lite) were assigned to nine experimental diets consisting of nine replicates (cage) and six hens per cage. A 3×3 factorial arrangement including three levels of vitamin E (0, 125 and 250 mg/kg diet from α-tocopherol acetate) and three levels selenium (0.0, 0.50 and 0.75 mg/kg diet from selenomethionine) was employed for six weeks trial period. The hens performance including hen-day egg production%, feed intake, egg mass (g/hen/day) and feed conversion ratio (FCR, g feed: g egg) were measured. Antibody production against sheep red blood cells (SRBC) also was measured. The general linear model procedure of SAS software was used for data analysis and differences among treatment means was determined using the Duncan’s multiple-range test. The results show that the in...
RESPONSE OF LAYING HENS TO DIETARY VITAMINS A, E AND SELENIUM SUPPLEMENTATION DURING SUMMER MONTHS
The current study aimed to investigate the effects of extra dietary supplementations of vitamins A, E and Selenium and their interactions on the performance of laying hens during summer months. A total of 243 Bovans laying hens 42 weeks old were randomly distributed into a factorial design experiment (3×3×3); including 3 levels of vitamin A (0, 8000, 16.000 IU/kg diet), 3 levels of vitamin E (0, 250, 500 mg/kg diet) and 3 levels of inorganic-selenium, (0, 0.25, 0.50 mg/kg diet). Results obtained showed that most values of live body weight and change in live body weight did not significantly differ due to A, E and Se supplementations and their interactions at all ages studied. Increasing the level of supplementations was associated with the decrease in feed intake and improving feed conversion. The effects of supplementations and their interactions were highly significant (P≤0.01) on feed intake and feed conversion. Increasing the level of vitamin A up to 16000 IU/kg diet had the highest (P≤0.05) monthly egg number and egg mass. Vitamin A increased (P≤0.05 and 0.01) each of egg length at 46 and 50 weeks of age and haugh units at 54 weeks of age. The higher level of supplemented dietary vitamin E led to a significant (P≤0.05) decrease in shell thickness and haugh units. Most of the egg quality traits fluctuated significantly (P≤0.05 and 0.01) with the high level of Se. The interactions among supplementations did not significantly affect egg quality traits. In conclusion, the results of the present study demonstrate that it may be suggested use each of vitamins A and E (together) at extra levels up to 16000 IU/kg diet of vitamin A and 500 mg/kg diet of vitamin E. Se levels need more investigations to detect its suitable level alone or with vitamin E in laying diets to reduce the negative effects of summer months.

ABSTRACT This study was conducted to evaluate the effect of different dietary level of vitamin E and organic selenium on the reproductive performance of Japanese quail breeders. A total of 252 Japanese quail birds aged 20 week with an average of 80 per cent egg production were used in this study. Trial birds were randomly divided into seven groups having male: female mating ratio of 1:3. Experimental birds were randomly divided into seven groups viz. T1- Control: Basal diet (standard Japanese quail ration), T2 - Basal diet with vitamin E 150mg/kg, T3 - Basal diet with vitamin E 300 mg/kg, T4 - Basal diet with organic selenium 0.3mg/kg, T5 - Basal diet with organic selenium 0.6mg/kg, T6 - Basal diet with combination of vitamin E 150mg/kg and organic selenium 0.3mg/kg, T7 - Basal diet with combination of vitamin E 300mg/kg and organic selenium 0.6mg/kg. The highest fertility (91 percent) and hatchability (Total eggs 80 percent; fertile eggs 89 percent) percentage were observed in experimental group which received vitamin E 150 mg per kg and selenium 0.3 mg per kg while the least fertility (78 percent) and hatchability (Total eggs 62 percent; fertile eggs 80 percent) percentage were recorded in the control group. From this study it can be concluded that dietary supplementation of vitamin E and organic selenium had highly significant (P<0.01) improvement infertility and hatchability percentage of Japanese quail. Key words: Japanese quail breeder, vitamin E, organic selenium, fertility, hatchability

The effect of dietary supplementation with VE and Se on the laying productive performance, immunity, and the quality parameters of fresh and stored eggs was assessed. For this study, five treatments, namely control (basal diet), control plus 30 mg of VE and 0.4 mg kg−1 sodium selenite (VE30SS), control plus 30 mg of VE and 0.4 mg kg−1 of Sel-Plex® (VE30SP), control plus 120 mg VE and 0.4 mg kg−1 Sodium selenite (VE120SS), and control plus 120 mg VE and 0.4 mg kg−1 Sel-Plex (VE120SP), were examined. There was no huge impact of VE and Se on feed consumption, FCR and egg yield rate. Quality parameters of fresh egg including egg surface area, eggshell thickness, yolk selenium concentration, albumen height, and Haugh unit were significantly increased following VE and Se supplementation (p < 0.05). For stored eggs, VE and Se significantly increased egg yolk color intensity (p < 0.05). Regardless of storage temperature, eggs from birds fed with VE and Se had less weight loss during 3...
