Fish wealth in Egypt is one of the sources of national agricultural income, as well as a source of safe animal protein sources, which provides food needs internally and develops other industries beside it. Egypt enjoys vast areas of water bodies suitable for production and development of fish resources, which qualify it to be one of the largest producing countries Not only at the regional level, but also at the international level. Fisheries in Egypt occupy vast areas. These sources vary according to their nature. They include the sea, such as the Red and Mediterranean Sea, and lakes such as Manzala, The problem of research is inspite of the fact that Egypt enjoys its position on the Mediterranean Sea and Red Sea and the existence of the Nile River and lakes, the quantity of fish produced does not sufficient for the needs of local consumption, which led to resorting to imports to bridge the food gap. The average  quantity of imports for the same period was estimated at 280.6 thousand tons. The average exports reached about 18.69 thousand tons for the same period. This means that there is a burden on the agricultural and national balance. The objective of the study is to study the development of national consumption And individual of the name The main results were that the relative importance of the value of exported fish during the period (20002015), where the first ranked fresh and salted fish with an engineering average of about 88.4% of the total The value of exports, while in the second place was for other varieties of fish with an average engineering of about 6.7% and the rest of the species (salmon, sardine, herring, tuna and sponge) ranked from third to seventh with an average of about 4.9% The study and the relative importance of the value of imported fish during the period 2000-2015. Toward 73.1% of the total value of imports, while the second place was fish tuna with an average of about 20.9%. The rest of the species (salmon, sardine, herring, crab, shrimp, caviar, anchovy, mackerel, and other varieties) With an average of about 6% of the total value of imports during the study period.

Direct-fed microbials (DFM) feed additives have been shown to improve average daily gain (ADG) and feed efficiency in ruminant animals in many studies. So, this study aimed to evaluate effect of using fungal and bacterial DFM and their mixture on productive performance of growing lambs. Thirty-two Barkey lambs (3 months old, 22.31± 1.57 kg) were randomly assigned into four groups, 8 lambs of each according to live body weight. The first group (control) was fed control rations without DFM supplementation, while treated groups (Fungal DFM, Bacterial DFM and Mixed DFM) were fed the control ration plus 2.5 g fungal, bacterial or mixed (1:1) DFM; respectively. Results showed that groups fed ration supplemented with DFM (fungal, bacterial and mixed) recorded higher DM, TDN and digestible CP intake. Supplementation of lambs ration with DFM (fungal, bacterial and mixed) showed not significant (P>0.05) effects on rumen liquor TVFA's and ammonia concentration at 0, 3 and 6 hrs post feeding. While DFM supplemented rations showed significant higher rumen liquor pH at 0, 3 and 6 hrs after feeding compared to the control group. Numerically increase was recorded in cellulose activity as unit per ml rumen liquor for groups fed ration supplemented with bacterial and mixed DFM. Direct fed microbial supplementation significantly (P<0.05) improved nutrients digestibility as dry matter, organic matter, crude protein, crude fiber, nitrogen free extract, neutral  detergent fiber (NDF) and acid detergent fiber (ADF) as well as feeding values as TDN and digestible crude protein. Bacterial or mixed DFM supplementation showed numerically increased (P>0.05) in plasma total protein concentration compared to lambs fed ration not supplemented. While albumin, globulin, urea, triglycerides, creatinine ALT and AST, alkaline phosphates activity were not significantly (P>0.05) affected by DFM supplementation. Total gain and ADG were significantly increased (P≤0.05) for groups received rations supplemented with DFM compared to control group. Also DFM supplementation significantly (P≤0.05) improved feed conversion as DM, TDN, CP and DCP compared to the control group. It could be concluded that supplementing lambs ration with fungal, bacterial or mixed DFM improved feed intake, digestibility, average daily gain and feed conversion without any adverse effects on animal health and performance.

Irrigation, water management under climate change conditions plays an important role in rationalizing water uses efficiency in the agricultural development processes specially under aridecosystems conditions. Therefore, the objective of this study was to estimate the irrigation water requirement of savings landscaping areas under different recent techniques. So, this study focused on comparison between fully automatic with central control system (C.C.S) based on weather station and Control unit based on operator experience and background. The experiments were conducted during two years (from January 2014 to December 2015), in the site that located in District 5, New Cairo, Cairo, Egypt.  The results indicated the irrigation scheduling based on weather station data using a central control system (C.C.S) optimized maximize the irrigation water use efficiency and increase the amount of irrigation water saving  by about  14%, 36%,18% and 33% in Autumn, Winter ,spring and summer  respectively  in year of  (2014) and 7%, 29.7%, 16%, 33% in Autumn, Winter, spring and summer,  respectively in year of  (2015) compared with the other irrigation scheduling when based on calculated according to traditional method. In addition,  the results revealed that scheduling practices based on weather station data by using central control system could reduce the average of power consumption (about 314 KW) in year of (2014) and (about 347 KW) in year of  (2015).  Moreover ,the results revealed that the cost of water consumption for the central control system based on the data of the meteorological station for the two years 2014 and 2015, the years of study  were 018601 L.E./ 2 years compared with the other irrigation schedule when calculated according to the operator's experience was 010101 L.E./ 2  years. Where the cost of 36172, 13603, 23393 and 33642  L.E./ 2 years in the winter ,spring, summer, autumn and respectively of the central control system and 39600, 17068, 28820 and 45522  L.E./ 2  years in the winter, spring, summer, autumn respectively of the other system.

The present work was aimed to evaluate Chenopodium quinoa cultivar CICA (Chenopodium quinoa Willd. cv. CICA), in field experiments, as a new and non-traditional leafy crop in Egypt under saline (ECe 17.9 dSm-1) and non-saline (ECe 1.9 dSm-1) soil conditions. Production of biomass, some morphological, physiochemical and yield components traits were estimated at 40 days from sowing date. Biomass production of young quinoa shoot under saline soil was significantly higher by 25% than non-saline soil. Quinoa plants cultivated under saline soil also showed significant high performances for most of morphological traits. Although salinity led to accumulate Na+ concentrations in the leaves by six folds higher than that found in the leaves produced under non-saline soil conditions, but no significant reduction has been observed for K+ concentrations. Moreover, salinity was significantly increased magnesium concentrations in quinoa leaves. On the other hand, no significant increase has been detected of proline or total soluble carbohydrates concentrations in leaves of quinoa grown under saline soil as compared to non-saline soil. This clearly indicated that quinoa plants, during early growth stage, tended to utilize inorganic ions rather than organic solutes to regulate its osmotic potential under saline conditions. Chlorophyll a, chlorophyll b and carotenoid concentrations were significantly decreased under saline soil. Also, concentrations of crude fiber, crude fat and iron in the leaves of quinoa plants grown under saline soil conditions were significantly decreased. Meanwhile, salinity has no significant influence on crude protein concentrations. These results revealed that the quinoa has the ability to grow and produce considerable high leafy vegetable yield with good quality, in terms of high protein, in land unsuitable for conventional vegetable crops.

Examination was done at preliminary bracketing bioassay on one old 4th nymphal instar of desert locust. Results showed that two isolates, namely NDL1 and NDL2 were having highly potentiality as entomopathogenic bioagents. Thirty isolates were isolated from dead/ infected nymphs of desert locust occurred in raring cages at Department of Locust and Grasshoppers Research, Plant Protection Research Institute, Agricultural Research Center, Dokki, Giza, Egypt. Molecular identification of isolated bacteria was done using universal primers of 16s rRNA, followed by DNA sequencing. Nucleotides were blasted at (https://www.ncbi. nlm.nih.gov /genbank/) to recognize that NDL1 and NDL2 isolates were two different isolates of Bacillus cereus with a high similarity (100%).  Susceptibility of 4th nymphal instar of Schistocerca gregaria (Forskal) to the isolated B. cereus was determined using two bioassay procedures, Leaf-dip and per os. The insecticidal activity of both isolates against locust nymph in leaf dipping showed that NDL2 was more efficient than NDL1. However, the opposite trend was observed in using per os.  Both Isolates have the potential to be a successful biocidal agent to control desert locust.

This investigation was carried out to study the effect of calcium chloride and storage period on fruit quality of Golden delicious apple cv. Collected at mature stage from private farm at Elbeida region. The fruits were stored at refrigerators of Horticultural Department, Faculty of Agriculture, Omar Al-Mukhtar University. Through the growing season of 2014/2015. The University, through 0.5 and 1% treatments contained three CaCl2 concentrations vis. 0, at five storage periods (0, 1, 2, 3, 4) weeks. Obtained results revealed that using CaCl2 at both concentrations improved most fruit quality parameters throughout storage periods.

The present Avian Influenza epidemic in Egypt is consider one of the major problems facing the poultry field and caused by circulation of genetically and antigenetically diverse influenza H5N1 viruses. This problem is controlled by applying vaccination. The objective was to determine the AI H5 recombinant vaccines efficacy (rHVT-H5, rFP-AI-H5 (Scotland and Ireland), k rND-AI and k rBuc-AI+ND) against classical and variant field HPAI H5N1 viruses in comparison to the traditionally inactivated whole AI virus vaccines as K R H5N1 / Egy, k H5N2 and k combined AI+ND vaccines. A single dose of the different types of vaccines either recombinant or inactivated whole virus vaccines was administered at different ages of chicken. Eight chicken groups were vaccinated with 8 vaccines and challenged after 4 weeks post vaccination to measure the protection %. Fecal and tracheal swabs were taken after 2 day post challenge to detect viral shedding. It was found that, live rFP-AI-H5 of both Scotland and Ireland strains induced poor clinical protection with high level of virus shedding. While, inactivated rND-AI, live rHVT-H5 and inactivated rBuc-AI+ND vaccines induced high protection rates ranged from 86.7% to 93.3% against both classical and variant HPAI viruses with a decrease or suppression of viruses shedding. In a parallel way, the inactivated whole virus AI vaccines either K R H5N1 / Egy, k H5N2 or k AI+ND induced a protection rates ranged from 85.7% to 100% with a high decrease in virus shedding levels. The data clearly indicate that inactivated whole AI virus and inactivated recombinant vaccines confers high levels of clinical protection with suppression in viral shedding compared to that of live recombinant vaccines except rHVT-H5 vaccine which induce a great level of protection and decrease in viral shedding in SPF chicken.

This study aimed at characterizing nutritional packages adoption by the small dairy farmers under crop-livestock production system. The study is based on quantitative and qualitative statistical analysis. A cross-sectional random survey covered a total of 200 farmers located in 4 governorates Sharqia, Monufia, El-Fayoum, and Minya (50 each). The socio-economic analysis indicated that the illiteracy level was higher (42%) in Minya governorate as compared to others. about half of the households (49%) have been working full time in their farms as farmer this means that they earn their living from agriculture. Family labor represented the highest percentage being 88%, 92%, 80%, and 86% for Sharqia, Monufia, El-Fayoum, and Minya respectively. The results further indicated that farmers who used silage, hay, and green forages, have the highest animal numbers, either from indigenous cows, crossbred cows, buffaloes, sheep, goat, and donkey compared to those who do not use the nutritional packages (non-adopters). The highest percentage of dairy, heifer, fattening, and growing for crossbred cows and buffaloes was detected under silage, hay, and untraditional green forages adopters comparable to those detected under non-adopters. Sharqia governorate had the highest number and consequently percentage of animals followed by El-Fayoum governorate. Silage adopters recorded the highest significant (P<0.05) value of daily milk yield (DMY) and total milk yield (TMY) for indigenous cow, crossbred cow and buffalo as compared to non-adopters. Calving interval significantly (P<0.05) increased for all dairy animals (indigenous cows, crossbred cows, and buffaloes) under non-adopters of nutritional packages being 387, 388.57, and 402 days for the aforementioned animals, respectively. Dairy animals reared under the Nile Delta had the highest significant DMY versus those under the Middle Egypt, where it was 4.05, 8.52, and 7.29 kg vs 3.76, 7.74, and 6.48 kg per day for indigenous cows, crossbred cows, and buffaloes, respectively. In conclusion, adopters of nutritional packages had the highest animal percent and recorded the highest productivity compared to non-adopters.

The response of different concentrations of α-amylase and ascorbic acid on rheological characteristics of weak wheat flour was studied by the three dimension polynomial quaternary model. Flour physicochemical characteristics, dough extensogram, bread texture profile analysis and sensory properties of pan bread were determined. All-purpose flour was treated by fungal α-amylase and ascorbic acid compared with strong flour which using for pan bread production, and then investigates differences of dough extensograms and pan bread quality characteristics. Predicting individual extensograph parameters (Y) was assumed by quadratic polynomial regression model for the independent variables (fungal α-amylase concentrations or ascorbic acid concentrations (X)) to optimize the extensograph parameters (Y) used regression analysis. Three-dimension contour plot was used as a method to study the response surface of different extensograph parameters (Y) as dependent variables with fungal α-amylase concentration and ascorbic acid concentration (X and Z) as independent variables. The obtained optimum predicting concentrations were verified, by using applied extensograph trials and then manufacturing pan bread. Using optimal predictive fungal α-amylase and ascorbic acid concentration levels give accepted extensogram parameters relationship r2 values and good pan bread quality, fit to the strong flour characteristics.

The aim of this study was to investigate the use of corn distillers dried grains with solubles (DDGS) (27.11% CP) and Foots (20.84% CP) as corn processing by-products in monosex Nile tilapia, Oreochromis niloticus diets to replace yellow corn as an energy source and its effect on growth performance, nutrients utilization, whole body proximate composition, nutrients digestibility and economic efficiency. Three hundreds and seventy five fingerlings of Nile tilapia (10± 0.05 g) were randomly distributed into 15 circular plastic tanks (1000 L), representing 5 treatments. Isonitrogenous (25 to 25.84%) and isocaloric (4174.79 to 4364.65 Kcal GE/kg) experimental diets were prepared with substitution levels of DDGS 0% (T1), 20% (T2) and 40% (T3) and Foots 20% (T4) and 40% (T5). The experimental period lasted for 18 week. Results showed that both of DDGS and Foots have higher in all measured amino acids content than those in yellow corn except cysteine. Moreover, DDGS and Foots have higher content of linoleic, oleic, stearic and palmitic acids than those in yellow corn. Also DDGS and Foots covered the nutrient requirements of the essential fatty acid linoleic (18:2 ω 6) for Nile tilapia. Feed intake was significantly decreased as corn partially replaced by Foots more than the DDGS. Apparent digestibility coefficient of CP, EE, NFE and energy recorded the highest values for the T4 (75.76, 89.86%, 57.48 and 68.71%), respectively, followed by T3 with significant differences. The increasing in substitution levels of yellow corn by DDGS did not significantly (P˃0.05) had an effect on Nile tilapia performances. However weight gain and specific growth rate SGR were gradually decreased with increasing the substitution levels of Foots. The CP content of Nile tilapia carcass was significantly increased with increasing the substitution levels of DDGS (T3) and Foots (T5). Feed conversion ratio (FCR) of the fish fed diets T4 (20% Foots) was the best followed by T5 (40% Foots). The cheaper feed cost gain was obtained from T5(40% Foots) followed by T4(20% Foots).
