A total of 12, 36-week-old of Muscovy drakes were divided randomly into three equal groups (4 individuals each) and subjected to supplementation of VE-Se in combine form in drinking water. The first group was served as control group (C), while the second and third groups (T1 and T2) were supplemented with 1.0g/l and 1.5g/l of VE-Se in drinking water, respectively. The study was performed at poultry research station which belongs to department of poultry production, faculty of agricultural, Ain Shams University and lasted 30-dayes period during summer season. Semen quality traits in terms of ejaculate volume (ml), spermatozoa concentration (×109), sperm motility (%), dead and live (%), PH value and abnormal sperms (%) were determined. Sperm reserves in ducts, seminiferous tubules diameter (STD) and relative spermatogenic activity were also studied. The obtained results indicated that addition of vitamin E-Se improved ejaculate volume, sperm concentration and motility score, while reduced the percentage of abnormalities and dead sperms. Results showed that semen ejaculate volume was significantly increased (P<0.05) with increasing the level of VE-Se supplementation in drinking water. Spermatozoa concentration, progressive motility (%), and packed sperm volume were increased significantly with VE-Se treatment. The percentages of dead and abnormal spermatozoa were significantly decreased (P<0.01) in VE-Se treated compared with the control drakes. Concerning with the effect of two levels (T1 and T2) of VE-Se supplementation in drinking water of Muscovy drakes on the morphometric traits of testis, the obtained results showed that highly significant effects of antioxidant (VE-Se) supplementation on the morphometric of seminiferous tubules (p < 0.05) and the higher values of sperm reserves and spermatogenic activity percentage in both T1 (4.4/ml×109 and 82.8%) and T2 (4.5/ml×109 and 83.0%) compared with control group (3.2/ml×109 and 61.3%). We conclude that VE-Se supplementation could lead to greater economic benefits through increased reproductive efficiency within the ducks production industry.

A total of 320 fertile eggs, were divided randomly into 4 treatments with four replicates and 20 eggs per each replicate. Treatments including: T1; control; without injection, T2; injected with 0.1ml saline solution; sham control, T3, injected with0.1 ml either containing 0.75 ppm inorganic or Nano – iron particles 75 ppm Fe-Nano inorganic, T4, injected with 75 ppm Fe inorganic  On the 7th day of incubation, 0.1 ml solution was In ovo injected into the egg .Body weight and body weight gain were measured at biweekly intervals, at 42d of age, three hens per replicate were weighted, sacrificed for slaughtering weights of carcass, internal organs(heart, liver, and lymphoid organs i.e. (spleen, thymus and Bursa) were recorded. Blood samples were collected at slaughtering bird at 42d of age. There were significant increase in body weight and body weight gain in treatments injected with75 ppm Fe-Nano inorganic and 75 ppm Fe inorganic compared with control. There were no significantly differences among all experimental groups in dressed carcass, gizzard, and heart, liver. Abdominal fat decreased in groups injectedwith75 ppm both iron forms. Compared with the control group. No variation was observed in the weight of bursa and spleen, however thymus weight was significantly higher in both Fe inorganic and Fe nano inorganic injected groups than un-injected control group. High density lipoprotein concentration and cholesterol were significantly decreased by different treatment as compared with the control group. These results suggest that, 75 ppm Fe inorganic or75 ppm Fe-Nano injection at the 7th im proved at the 7th day of incubation improved embryonic growth and development as well as decreasing post hatched chick's plasma cholesterol.

One day old wheat grain sprouts were used to study the effect of using saline water for sprouting on sprout characters, and changes of some chemical compounds after 2 years wheat grain storage of Gemmeiza 11 cultivar. Sprout characters showed no significant different in storage grain sprouts weight at all NaCl concentration while increased in fresh grains sprouts with increasing NaCl concentration. Sprouts chemical components as affected by storage revealed that storage Gemmiza II had the highest crude protein and the lowest carbohydrate content compared with dry fresh seeds. Non storage grains also had higher protein and lowest carbohydrate and energy content compare with dry fresh grains. The results of phytochemical analysis showed that wheat fresh grain sprouts increase phytochemical compounds and recorded the higher values when using saline water (37 compounds) followed by using tap water (33 compounds) compared with dry fresh grains (30 compounds). Saline water also enhanced the number of phytochemical compounds in two year storage grain sprouts (31 compounds vs. 28 compounds for tap water). Moreover, storage grains decreased the number of identified compounds during sprouting. It can be recommended that wheat grain sprouting is a procedure that has been developed to significantly increase the bioavailability of phytonutrients and phytochemical to ensure the nutritional security of population for Egypt.

This work was carried out to study the effect of using some natural dietary supplements; i.e. powders of date palm pits and pollen, ginseng roots, moringa leaves and royal jelly which giving orally in capsule to improve endurance of weightlifter athletes throughout 12 weeks in camp of sport Championship Sector belongs to the Armed Forces, Ministry of Defense, Future City, Cairo, Egypt. Collecting data showed that the suggested dietary supplement capsule had the highest value of the antioxidant activity (96.3%) and significant increases in total phenolic and flavonoids content (52.42 & 63.1 mg/g, respectively). Also, the anthropometric measurements showed a significant increase in weight and height in males compared to females. likewise, waist and mid upper arm circumference had significant increases in males compared to females, Male weightlifter athletes had significant muscles mass bigger than female one, and the fat mass for male was assessed as ‘‘Fitness’’ which ranged between (14 and 17%) but the female had fat mass that assessed as ‘‘Athletes’’ which ranged between (14 and 20%). The weights lifting by male and female increased during three months, and also revealed a significant increase in the efficiency of males in lifting weights higher than in the females during the period of 12 weeks. Thus, the results indicated that by incorporating natural dietary supplement powders in suggesting capsule, it is possible to enhance the performance of weightlifter athletes.

This study aims to study the estimation of production cost functions as it reflects the relationship between total costs and actual production. The main economic indicators that reflect the extent to which the agricultural production units achieved economic efficiency in their use of the productive resources involved in the production process as well as the extent to which they are achieved These units of maximizing the profits of the agricultural product, as well as the study of production costs and the associated indicators are important  both on the productivity unit or at the national level, which can be used in the design and analysis of price policies and help the user Farmers in their productive decision-making, which would encourage producers to continue production or stop production. As well as to determine the volume of production that maximizes profits and thus achieve economic efficiency of the use of productive elements.

he aim of the present study was to optimize the extraction conditions of green tea aqueous extract [green tea concentration (G) and extraction temperature (T)]. Response surface methodology was applied to determine the highest radical scavenging activity (RSA), Ferric reducing antioxidant power (FRAP) and reducing power (RP) of the prepared green tea extract. Effect of green tea aqueous extract prepared using the optimal conditions on the liver cirrhosis retardation in rats was also investigated. Two-factors central composite design was established to determine the effects of G or T and radical scavenging holding time as independent variables on RSA, FRAP and RP as dependent variables. The optimum G, T and holding time with maximum RSA were 1.0 %, 88.7 °C for 25 min, with a predicted RSA of 81.3 % (r2=0.9115) compared to the BHT, which had a scavenging value of 87.4 % at concentration 150 ppm and holding time 30 min The same predicted concentration and temperature obtained with the highest FRAP and RP were 2.566 and 1.687 with r2 0.9780 and 0.9550, respectively. The phenolic and flavonoid contents were 81.2 mg gallic acid equivalent and 33.5 mg quercetin equivalent per 100 ml green tea extract. The extract prepared at optimal conditions was used for treatment of cirrhotic rats by CCl4. Insignificant (P≥0.05) differences were observed between the green tea group and control group in obtained total protein or albumin values. Total protein and albumin were dramatically decreased in the group treated by CCL4.  The same trend was observed with studying the transaminase enzymes. Histopathological sections appeared the effect of green tea extract on the retardation of liver cirrhosis in rats.

The paper shows the development of strawberries crop area in Behera governorate during the period 2001-2015 showing that its lower area was about 150 feddan and its maximum area was about 2320 feddans. The general time trendof area was 120 feddans a year during the studied period.  Strawbarries production, on other hand, was between 600 ton and 6830 during the above period.  Despite the importance of strawbarries are in the governorate, its total production was only 42.731 or 48% of total production in Egypt. This may be explained by the low productivity of most varieties cultivated by farmers. For this, the study is concerned with the cultivation of varieties with high productivity per feddan.   The study depends on the results of a sample of farmers in the governorate to estimate production and cost functions to evaluate factors affecting these functions. The study reveals that the sample farmers in Kom hamada-which represents about 81% of total strawbarries production are producing in the first stage of the production function. This means that farmers do’ nt  use the optimum method of production. The study estimate cost production and the size of farm that minimize cost and that maximize profit for the farm four groups and for the total sample.

The wide and indiscriminate use of pesticides for pest control in agriculture has inflicted serious harm and problems to humans as well as to the biodiversity. Microbial degradation of pesticides in contaminated soils has been considered advantageous to decontaminate areas that have been polluted by pesticides. Chlorpyrifos and diazinon were the most persistent residues in Egyptian soils. Four bacterial isolates were isolated from organophosphorus insecticides contaminated soils and genetically identified based on DNA sequence of 16s rDNA gene, Cronobacter muytjensii GH10, Achromobacter xylosoxidans GH9OP, Pseudomonas aeruginosa GH2NO8 and Pseudomonas putida GH4SNO/P were able to degrade 92.59%, 97.75%, 91.82%, and 90.78% of diazinon (600mg/l) as compared with 16.99% in control and 93.43%, 78.51%, 93.18% and 95.36% of chlorpyrifos (480mg/l) as compared with 4.28%, in control, respectively after 20 days of incubation.

Baby pea (pisum sativum L.) shoots is a new ready to eat baby leaf vegetable sprouts in Egypt. The overall quality change of baby pea shoots is greatly affected by surrounding environmental conditions especially increased elevation of carbon dioxide concentration in the air. This work focus on the impacts of predicted climate changes conditions on the quality of baby pea shoots by using two carbon dioxide concentrations (600 and 800 ppm) compared with ambient air (control) in interaction with three microbial inoculants and their combinations, in semi-automated growth chambers using tray sprouting method. The obtained results showed the largest yield of pea sprouts per unit area in 800 ppm CO2 concentration with increasing about 20% more than ambient air (control) followed by 600 ppm with increasing about 9.4% than ambient air. Also, it revealed that using CO2 at 800 ppm increased pea sprout crude protein content 37.8%, lipid 46.9% and energy 19.5% per unit area when compared to ambient air. While pea sprout treated by 800 ppm CO2 and inoculated by combination of  Az. chroococcum + B. megaterium + Ps. fluorescens recorded the highest significant shoot length in the second cut and highest significant chlorophyll in first and second being 13.25 cm, 57.3 and 58.9 μg Chl./cm (SPAD) and the highest significant protein, lipids, and ash content being 48.65, 4.95, 10.69% as well as the highest significant mineral values of P, Ca, Mg, Fe and Zn being 0.545, 3.535, 0.620% and 61.3 ppm respectively. Current study suggests that high CO2 concentration in the presence of Az. chroococcum + B.  megaterium + Ps. fluorescens improve the yield and the quality of baby pea shoots.

Natural sources of water are limited in Egypt. The rapidly growing populations necessitate continuous expansion of the cultivated area. This means an increase of the gap between the demands of water for irrigation and the limited water supply. Looking for other sources such as low quality water like (industrial effluent, drainage and sewage) must be used in irrigation of some garden and wood plants. This investigation was conducted on agricultural drainage wastewater from El Mohete drain (Marioteya Canal) west of Cairo; the samples were collected from different places during (Summer and Winter seasons). The wastewater contaminated with pathogenic microorganisms, the excess of fertilizers (inorganic & organic), heavy metals, and the residuals of pesticides. Plant Growth Promoting Rhizobacteria (PGPR) could remediate the wastewater as biological bioremediation to remove some pollutants such as pathogenic microorganisms, heavy metals and pesticides. Chemical remediation was used as nitrification inhibitor to stop transformation of ammonia to nitrate. This work was conducted to study the ability of PGPR strains e.g. Bacillus megaterium, Bacillus subtillis, Bacillus circulans, Paenibacillus polymyxa, Pseudomonas floresense, Serratia sp. and Azotobacter chroococcum 5, 9 and 23 to treat the drainage water for irrigation the Mentha viridis cv. and Gladiolas grandiflorus cv. plants.                 Two pot experiments were conducted in greenhouse. The treatments were applied as follows; Natural water, treated water and drainage water to irrigate the plant. Use the PGPR as inoculants and thiourea as nitrification inhibitor, Heavy metal treated was (Copper, Cobalt, Zinc, Cadmium and Mercury) the result showed us heavy metals removal by PGPR from drainage water. The characterizations of PGPRs as shown in the obtained results are they could enhance plant growth by using their own metabolism (solublizing phosphate, producing hormones or fixing nitrogen) as well as correlation of them with the potenit of effects on the growth of plants in unfavorable conditions in order to improve the efficiency of phytoremdiation of contarinated soils. The removal of heavy metals and the elimination of pesticides residues were markedly noticed in this investigation. Results also confirmed the ability of PGPRs in suppressing the effect of pathogenic bacteria like Salmonellasp and E.coli. These abilities are of great importance in terms of plant and soil health. Consequently, the role of PGPRs bacteria associated with plant rhizosphere in remediation of water and soil contaminations due to its biochemical activity and thus, stimulate plant growth is a great important subject in phytoremediation process nowadays.
