: This experiment was carried out to evaluate ability of some plant feed additives to replace synthetic vitamins, prebiotics and antibiotics in feeding layers Japanese quail layers reared under chronic heat stress. Two hundreds females and 80 males of Japanese quails were selected and distributed randomly into 10 experimental treatments with 4 replicates per each. Each replicate hold 5 female and 2 male. Ten experimental supplementations were added to basal diet (control treatment) to compose 10 experimental treatments. The other 9 treatments were formed by adding 0.5gm oxytetracycline (20%) /kg diet, 200mg vitamin C/kg diet, 20mg vitamin E/kg diet, 1gm pectin/kg diet, 20gm entire fresh lemon (fully grinded) /kg diet, 250 mg silymarin (Si) /kg, 250 mg curcumin (CR) /kg, 500 mg SI /kg and 500 mg CR /kg respectively. The experiment extended from 8 weeks of age up to 2 months of egg production. The results showed that: Egg production performance of quail fed diet supplemented with fresh lemon equalized with vitamin E and recorded (p ≤ 0.05) significantly higher egg production performance than vitamin C, pectin, antibiotics and other plant feed additives. On contrast laying quail fed diet supplemented with 500 SI mg CR/kg recorded numerically the highest fertility and hatchability percent. Similarly egg quality improved numerically with silymarin supplementation. The results of this experiment recommend that some plant feed additives that are available with low cost may be able to substitute antibiotics, synthetic vitamins and prebiotics in diets to improve performance of laying quail reared under chronic heat stress.
本试验旨在评价几种植物性饲料添加剂在慢性热应激饲养的日本鹌鹑饲蛋中替代合成维生素、益生元和抗生素的能力。选用日本鹌鹑母鹑200只，公鹑80只，随机分为10个处理，每个处理4个重复。每个重复容纳5名女性和2名男性。在基础饲粮(对照组)中添加10个试验添加物，组成10个试验处理。其余9个处理分别添加0.5gm土霉素(20%)/kg日粮、200mg维生素C/kg日粮、20mg维生素E/kg日粮、1gm果胶/kg日粮、20gm全鲜柠檬(磨碎)/kg日粮、250 mg水飞蓟素/kg、250 mg姜黄素(CR) /kg、500 mg Si /kg和500 mg CR /kg。试验从8周龄延长至产蛋2个月。结果表明:在鹌鹑饲粮中添加与维生素E相当的鲜柠檬，其产蛋性能显著高于维生素C、果胶、抗生素和其他植物性饲料添加剂(p≤0.05)。相比之下，产蛋鹌鹑在饲粮中添加500 SI mg CR/kg时的受精率和孵化率最高。同样，添加水飞蓟素后，鸡蛋品质也有了数值上的提高。本试验结果提示，一些成本较低的植物性饲料添加剂可以替代饲粮中的抗生素、合成维生素和益生元，提高慢性热应激条件下蛋鹑的生产性能。

: This work aimed to study the effects of selenium nanoparticles and nicotinamide in-ovo injection on hatchability and physiological traits of broiler chicks at hatch day. A total of 500 eggs from Arbor Acres breeder hens were weighed and distributed into five treatments with four replicates for each. At day 18 of incubation, eggs of the first group were non-injected and served as control, while the 2 nd group was injected with normal saline at 0.9 % (saline group). But, the 3 rd group was injected with selenium nanoparticles (SeNPs) (20 μg SeNPs/ egg) the 4 th group was injected with nicotinamide (NAM) (300 mM NAM/ egg) and the 5 th group was injected with their mixture (20 μg SeNPs plus 300 mM NAM/ egg). The results showed that chicks of saline and mixture in-ovo injection groups had higher significant weights at hatch compared to all other studied groups. In contrast, eggs of the in-ovo NAM injected group had higher hatch of fertile egg percentage values with insignificant differences with both control and mixture injected groups. The chicks of NAM and mixture in-ovo injected groups had significantly highest WBC values compared to all other studied treatments. The chicks of SeNPs, NAM, and mixture in-ovo injected groups have significantly higher low-density lipoprotein compared to control and saline groups. This suggested that the in-ovo injection with NAM and the mixture groups used in the present study had a considerably positive effect on hatchability percentage, chick weight, relative chick weight, white blood cell count, and blood glucose level and the activity of total antioxidant capacity (TAC). In conclusion, injection of eggs in-ovo of broiler chicks with 300 mM nicotinamide/ egg and mixture between 20 μg SeNPs plus 300 mM NAM/ egg enhanced hatchability and some physiological traits for chicks.
本试验旨在研究纳米硒和烟酰胺在蛋内注射对孵化日肉鸡孵化率和生理性状的影响。试验选用500只爱拔益加种鸡，称重后分成5个处理，每个处理4个重复。孵育第18天，第一组不注射卵作为对照，第二组注射0.9%生理盐水(生理盐水组)。第3组注射纳米硒(SeNPs) (20 μg SeNPs/鸡蛋)，第4组注射烟酰胺(NAM) (300 mM NAM/鸡蛋)，第5组注射两者混合(20 μg SeNPs + 300 mM NAM/鸡蛋)。结果表明:盐水和混合蛋内注射组雏鸡孵化时显著体重高于其他各组。相比之下，在蛋内注射NAM组鸡蛋的孵化可育蛋率值较高，但与对照组和混合注射组差异不显著。与其他处理相比，NAM和混合蛋内注射组的WBC值显著最高。SeNPs、NAM和混合蛋内注射组雏鸡的低密度脂蛋白显著高于对照组和生理盐水组。由此可见，在蛋内注射NAM和本研究使用的混合组对孵化率、鸡重、相对鸡重、白细胞计数、血糖水平和总抗氧化能力(TAC)活性均有显著的正影响。综上所述，在肉仔鸡蛋内注射300 mM烟酰胺/蛋和20 μg SeNPs + 300 mM NAM/蛋的混合物，可提高鸡的孵化率和部分生理性状。

: This experiment was conducted to study the association between eggshell color and: productive performance, body measurements and some plasma constituents in Golden Montazah chickens. A total number of 300 Golden Montazah hens, 30 weeks old, were housed individually. Hens were divided into three groups according to their eggshell color (Light Brown, Creamy or White). Blood samples were taken to measure the sex hormones, phosphors and albumin contents and to determine the immune response against Newcastle and H5N1 diseases. Results showed that no significant differences in body weight, comb length, and shank length between females that produced different eggshell color. Wattle length was significantly larger in females produced creamy and light brown shell than females produced white eggshell color. Keel length was significantly longer in females that produced light brown eggs than those that produced Creamy or White eggshell colors. No significant differences in keel length was found between females that produced Creamy or White eggshell colors. No significant differences in egg production were observed between hens that produced different eggshell colors. Egg weight was significantly higher in creamy and white eggshell color than the light brown color group. Also, egg mass was significantly higher in the creamy shell group than the white shell egg group. Shell thickness was significantly higher in Light brown eggs than Creamy or White eggs. Blood Phosphors percentage and albumin percentage, at 42 weeks of age, were significantly higher in females that produced creamy and white eggs than light brown shell color. Antibody titer against H5N1 was significantly higher in hens that produced white eggshell color than hens that produced creamy shell color eggs. No significant differences were observed against Newcastle disease between females produced different eggshell color eggs. Also, no significant differences were observed in estradiol and progesterone hormones in Golden Montazah females produced different eggshell color eggs.

The present work was deliberate to study effect of prebiotic, probiotic or combination of prebiotic and probiotic as synbiotic on productive measurements as growth and slaughter yield, digestibility of nutrients, blood indicates and some intestinal bacterial counts of broiler chicks. A total of 120Arbor Acresat one day of age chicks were classified into four treatments (30 birds each). Broilers in the control clutch (T1) were fed starter and grower diet without supplementations. The second group (T2) was fed the same control added with 5.00 g (MOS) mannanoligosaccharides (as prepiotic). The third group (T3) was fed the same control diet plus 1.00 g Inviva-pro (as probiotic). Whereas, the fourth one (T4) was fed basal diet supplemented with mixture of 5.00g mannanoligosaccharides plus 1.00 g Invivapro (as synbiotic) during starter and grower diet (from 1 to 20 and from 21 to 35 days old). The obtained data showed that the mean values of live body weight and body gain were highest (P < 0.05) for probiotic group (T3), feed effeciency was greatest (P < 0.05) in synbiotic group (T4) and feed intake had no significant changes among all treatments. The total count of bacteria in small and large intestine was significantly higher in treatment (T2) followed by (T3) as compared to the other treatments. Dressing yield percentage and liver weight significantly increased for broilers in T3 (probiotic) and T4 (synbiotic), respectively. There were no variances (P < 0.05) in digestibility of all nutrients for broilers in all treatments. Number of Lactobacilli in both small and large intestine was higher in all treatments than in the control (T1). In addition, The highest number of coliform was recorded in T4 (synbiotic) in small intestine with no significant differences in large intestine.. The highest values of amylase, lipase and trypsin were determined to T3 broilers. While, the highest value of chymotrypsin activity was recorded to T4 broilers. The highest (p˂0.01) total protein, globulin, triglycerides and basophils were recorded to synbiotic broilers group. In addition, probiotic group (T3) recorded the greatest values of glucose and neutrophils. Highest economic efficiency and relative economic efficiency were calculated to probiotic group.

: The aim of this study was to investigate the influence of Calendula officinalis flowers either as a powder (COP) or as an extract (COEx) on productive, digestion enzymes, nutrient digestibility coefficients, egg yolk cholesterol, serum metabolites, gut bacterial content, antioxidant capacity and immunological traits in laying Japanese quail. 504 hens (168 males and 336 females), at 9 th weeks of age were randomly distributed to seven experimental treatments, with six replicates of 12 birds each (four males and eight females). The first treatment was received a basal diet (control), groups from two to four fed on the basal diet supplemented with 0.6, 0.9 and 1.2 % COP, respectively. While, groups from five to seven were fed on basal diet supplemented with 150, 200 and 250 ppm COEx, respectively. Hens fed with 1.2% COP, 200 and 250 ppm COEx levels had significantly (p ≤ 0.001) higher egg number, egg production %, egg weight, and egg mass with the best feed conversion ratio without holding significant effect on feed intake. Egg yolk cholesterol was significantly (p ≤ 0.001) decreased in quails treated with 250 ppm COEx 1.2 % COP and 200 ppm COEx, respectively. Serum biochemistry (total cholesterol, TG, HDL and LDL), liver functions, antioxidant parameters, immune response and some gut bacterial count ( Lactobacillus ) were significantly (p ≤ 0.001) improved by some treatments. Digestive enzymes were significantly (p ≤ 0.001) improved by treatments with COP and COEx especially at 250 pm COEx. Finally, quails fed diets containing 0.6 % COP and 250 ppm COEx had significantly (p ≤ 0.001) the highest nutrient digestibility percentage. The present study concluded that the dietary supplementation with 200 and 250 ppm COEx to laying quail improved digestive enzymes, digestion of nutrients, productive performance, serum biochemistry, immunological parameters, antioxidant capacity, and gut microbial content.

: A study was performed to investigate the effect of dietary protein level and addition of yeast or exogenous enzymes on growth performance and carcass characteristics of Japanese quail. A factorial completely randomized design (3×3), three dietary protein levels (24, 21.6 and 19.2%) without or with two feed additives was used. Five hundred and forty quails were randomly divided into nine groups, kept in cages, fed their respective experimental diets and managed similarly from 2 to 6 weeks of age. The obtained results illustrated that growth performance of quails did not affected by dietary protein level. Quails fed enzyme-enriched diets achieved better feed conversion than the control birds. Feeding yeast-supplemented diets improved the final body weight and weight gain of quails compared with the control birds. Economic efficiency of feeding (EEF) and carcass characteristics were not influenced by dietary protein level, feed additives and their interaction. In conclusion, decreasing dietary CP level from 24 to 19.2% does not compromise the growth performance, economic efficiency or carcass traits of quails. Dietary yeast supplementation has a beneficial effect on growth performance of quails, regardless of dietary CP level.
