Hanan Ghaly | Mona Emam | Manal Salah
The poultry production sector occupies an important position among the animal production sectors, as one of the main sources of animal protein in Egypt, with a value of about 32.4 billion pounds, representing about 28.9 % of the value of animal production in 2014. This is due to the features of this sector of the short production cycle, the speed of capital turnover, as well as the high economic return. The problem of the study is the large variation in poultry prices between production areas and consumption areas, Indicating an inefficient transport system, which is considered one of the most important marketing services for this fast food commodity death under the prevailing climatic conditions, thus ensuring that they reach the consumer as quickly as possible. The study aimed is to propose the best transportation model to transport poultry production from surplus with poultry to those of shortage with poultry governorates, to reach the shortest distance marketing to minimize transport costs and time. The study used the transportation problem as one of the operation research tools to rationalize the poultry redistribution between surplus and shortage governorates during three scenarios. The study showed under the assumption of the first scenario (production and consumption are expected firming), that the expected quantity to be transported to the shortage governorates to be about 817.4 thousand tons represent about 25.3% of the total production of the republic during the year 2020, Under the proposed model, the least cost of the transfer is estimated at 69.9 million units/km / ton, are estimated quantities transported about 2.5 million tons, represent about 78.1% of the total production at the level of the republic of that model estimated at 3.2 million tons during 2020. The study also showed that under the assumptions the second scenario (lower production 10% and consumption firming), that the expected quantity to be transported to the shortage governorates to be about 850.7 thousand tons represent about 29.2% of the total production of the republic, Under the proposed model, the least cost of the transfer is estimated at 76.9 million units / km / ton, are estimated quantities transported about 2.2 million tons, represent about 75.8% of the total production at the level of the republic of that model estimated at 2.9 million tons. Under the assumption of the third scenario (Production firming and lower consumption 10%) that the expected quantity to be transported to the shortage governorates to be about 702.3 thousand tons represent about 21.7% of the total production of the republic, Under the proposed model, the least cost of the transfer is estimated at 573. million units / km / ton, are estimated quantities transported about 2.5 million tons, represent about 78.1% of the total production at the level of the republic of that model estimated at 3.2 million tons. The study recommended the use of scientific methods to rationalize the transport process between the governorates thus achieving cost and time to transfer at least on the side and the other side reduce wastage circulation which serves to provide the appropriate poultry prices.

Tumor Necrosis Factor-α (TNFα) is a cytokine signaling protein which has an important role in the immune system regulation and affect female reproductive performance. The objective of this study was investigation the TNFα gene polymorphism and its potential effects in female buffaloes fertility. The DNA was extracted from the blood of 81 buffalo females and a 592 bp fragment contains the full coding region of TNFα-exon 4 was amplified by PCR which subsequently treated with RsaI restriction enzyme. The PCR-RFLP pattern showed that all the animals had fixed CC genotype and T allele was not detected. Sequencing of amplified fragment (GenBank accession No. KY885010) flowed by sequence alignment with GenBank database revealed that the river buffalo target sequence was homologues to cattle than goat, sheep, human and mouse on DNA and amino acids levels. Comparison of TNFα amplicon with homologues Bubalus bubalis records in the GenBank detected 3 SNPs in exon 4. Two of these SNPs were synonymous while the third located in the 3` UTR. Different effects of some of discovered SNPs on RNA cis-regulatory elements and hn mRNA and mature mRNA secondary structures were predicted.

F. Mohamed | K. Abdel-Hamid | Genesia Omar | Basma El-Safty
This study was conducted to examine explant density and source on production of in vitro potato microtubers, as well as survey of different newly-introduced potato cultivars for their microtuberization capacity at the Plant Tissue Culture Facility of the Department of Horticulture, Suez Canal University between 2014 until 2016. Results indicated that as culture density from single node explants increased, microtuber number and yield/petri dish were also increased. However, at the lowest density (10 explants/petri dish), the % tuberization and the average microtuber weight increased significantly over the higher densities (20, 25 and 30 explants/petri dish). Potato microtuber production from plantlets grown in vitroon microtuberization induction medium (liquid over solid media) was also studied using 5, 10 and 15 plantlets per jar.Results showed that microtuber number and yield/jar increased gradually with increasing plantlet density. However, on per plantlet basis, microtuber number increased at the lowest density. Microtuber yield/jar increased significantly at the highest density (1099 mg/jar) compared to 563.6 mg/jar at the lowest density. Average microtuber weight was also affected by culture density and genotype. At the lowest density, microtubers were significantly heavier than at the high density, and the cv. 'Safrane' recorded the highest weight per microtuber. Regarding the effect of explant source on microtuber production, results indicated that the use of single node explants derived from the top of the plantlet produced more microtubers than those taken from the basal part, or 3 node segments. Explant source also affected microtuber yield/dish. Single nodes from the top produced the highest yield compared to 3-nodes segment from the top (205 vs. 104.8 mg). The highest mean microtuber fresh weight was obtained from the culture of 3-node layered segment from the plantlet base, while single nodes from the top recorded lower microtuber fresh weight. The highest microtuber fresh weight was recorded in cv 'Universa' (114.3 mg) using single nodes from the plantlet base. Differences among the tested potato cultivars in microtuber production were detected.

M. Mileek
Sugar crops are considered to be the most important strategic food commodities, which attract the attention of decision-makers and producers who are concerned with the availability of supply in the markets, the deficit and the food gap. Sugar production depends on two crops in Egypt: sugarcane and sugar beet. A sugar gap due to the inability of the supply of domestic sugar to meet the demand for increased consumer needs, resulting in higher prices. The study aims to study the current situation of the production and consumption of sugar crops in Egypt and to estimate the food gap of sugar. Also, study the most important factors affecting the production and consumption of sugar crops in Egypt and the self-sufficiency rate. Of sugar The research was based on descriptive and quantitative analysis of the economic variables, the subject of the research to measure those variables and the research reached the following results. The cultivated area of sugar cane and sugar beet has taken an increasing general trend, which is estimated to be about 0.6, 37.7 thousand feddans annually, respectively, representing about 0.19%, 11.3% of the average during the period (2005- 2015) 324.3, 334.6 thousand acres, respectively. The total production of cane sugar has taken a general trend is decreasing, and did not confirm the statistical model, that is, there is relative stability length of study. The production of sugar beet crop has taken an increasing trend, which is estimated at about 810.8 thousand tons annually, representing about 11.6% of the annual average and estimated at 7002 thousand tons. The total amount of sugar produced from both sugar cane and sugar beets has taken an increasing general trend, and did not confirm the statistical significance, that is, there is relative stability throughout the study period. The food gap of sugar amounted to about 50.35 thousand tons, representing about 1.71% of the average national consumption of sugar, which amounted to 2937 thousand tons during the same period. Self-sufficiency rate of sugar amounted to about 63%, has taken a general trend decreases, and did not confirm the statistical significance, there is relative stability length of the study period. The study of the most important factors affecting the production of cane and sugar beet separately showed the existence of a positive relationship between the total production of each crop separately and the area and productivity of each crop separately, respectively. Study the factors affecting the consumption of sugar during the period of research shows the existence of a positive relationship between national consumption of sugar and the income of the consumer per pound / per year, local production of sugar per thousand tons, and the monetary value to support sugar per million pounds, and the opposite of the amount of national consumption of sugar and the retail price of sugar per kilogram per kilogram and the average global price in dollars / ton.

L. Youssef
The toxic effect of Abamectin and Pyriproxyfen action on the 1st instar larvae of the pink bollworm, Pectinophora gossypiella (Saund.) was studied under laboratory conditions. The toxic action of the tested compounds at their estimated LC50 values on some biological aspects of the treated insect as well as total protein content and the activity of b-esterase in the affected larvae were also studied. Based on the obtained results, abamectin was more toxic than pyriproxyfen after 24, 48 and 72 hr of treatment. In addition, the effect of treatment with the LC50 value of both tested compounds on newly hatched larvae was extended to the following developmental stages, represented as some morphological deformities. Also, total protein content in treated larvae increased than their control when Pyriproxyfen was tested but decreased when Abamectin was administered to larval diet. The electrophoretic analysis using SDS-PAGE for β-esterase enzyme in the larval stage fed on diets treated with tested compounds showed clear variation in the dense and number of enzyme bands.

The current study aimed to investigate the effect of microbiological treatment on improving the nutritive value of corn silage as animal feed. Dried whole corn plants were prepared and two ground silos (0.5 ton each) wereused for ensiling whole corn silage and inoculated by bacterial inoculant (containing Lactobacillus plantarum and Entrococcus faecium) at the recommended rate of 1/2g bacterial inoculants/liter of water/ton of fresh whole corn silage. The ensiling period lasted for 50 days. The criteria of response were determined by: the quality of treated corn silage, chemical characteristics and performance of rams, nutrients digestibility and nitrogen balance. Results for treated and untreated silage, respectively, showed that the silage had pH 3.71 and 3.69, Total Volatile Fatty Acids (TVFA) were 2.48 and 1.98 mmol/100ml, and NH3-N values were 6.1% and 6.41% (on dry matter basis). The values of organic matter (OM), crude protein (CP), crude fiber (CF), ether extract (EE), nitrogen free extract (NFE) and ash content on dry matter basis, however, were very close in the two rations. There were no significant differences between the two rations for the dry matter (DM). The value of CF digestibility was not significantly different from that in treated corn silage, while ration contents of treated corn silage were significantly higher in OM, CP, NFE and EE digestibility than the untreated corn silage. Recorded values for total digestible nutrients (TDN) and starch value (SV) of rations of treated corn silage were significantly higher than those of untreated corn silage being 52.64 and 63.37 vs. 43.53 and 56.09%, respectively. The digestible crude protein (DCP) values were (7.43%) for ration of treated corn silage by 5.96% for the ration of untreated corn silage.

This study was carried out during 2013-2014 and 2014-2015 seasons at a private farm located at Tokh district, Qalubia Governorate. Strawberry fruits ˝festival cultivar˝ to study the effect of active (7.5% O2 +15% CO2 or 10% O2 +10% CO2) and passive modified atmosphere packaging (MAP) on preserving the quality parameters and extend the shelf life of fruits during storage at 0˚C plus shelf life at 10˚C.The results showed that active MAP inhibit the weight loss and decay percentage, maintained fruit texture, ascorbic acid, titratable acidity (TA) and decrease in color development during storage and shelf life. Passive MAP was less effective in reducing the loss of fruits texture, TA and ascorbic acid content. Untreated MAP (control) gave the highest values of weight loss and decay percentage and lowest values of texture, becoming more red and poor appearance after 15 days of storage at 0˚C + 2 days at 10˚C. The results showed also that the optimum gas composition of MAP tests for strawberry was 7.5% O2 +15% CO2. No decay was observed in active MAP at 7.5% O2 +15% CO2 during the storage period plus shelf life. Furthermore, it also retarded texture, color, titratable acidity and ascorbic acid content. Finally, the study concluded that storage of strawberry fruits at active MAP of 7.5% O2+ 15% CO2 improved storability of fruits, and maintained fruit quality and gave fruits with good appearance till of 15 days at 0˚C + 2 days at 10˚C without decay. The shelf life of strawberry after harvest can be extended to 3 days at 0˚C + 2 days at 10˚C by this treatment.

Abd El-Rady F. | Nagwa Rasmy | Nessrien Yasin | Abd El-Razik M. | Fahmy A.
For improving the safety of filling cream, the Hazard Analysis Critical Control Points (HACCP) system was applied during different preparation process. Different biological, chemical, and physical hazards that may exist in every preparing step of filling cream were identified and control measures were used for controlling those identified hazards. Dried milk powder was identified as high potential hazard raw materials contaminated with pathogenic bacteria e.g. S. aureus and Salmonella sp. Whipping step in preparing filling cream was identified as critical control point. For improving the safety of preparing filling cream system, different control measures including, thermal processing (pasteurization), addition of natural preservatives (lemongrass oil and herbs of cinnamon, clove and anise) and reduction of pH (fruit pulps of strawberry, apricots and apple) were established. Different applied control measures could be used for improving the safety of prepared filling cream where different investigated microbiological criteria were reduced to acceptable levels especially pathogenic bacteria. In addition, different HACCP principles as the critical control points, critical limits, monitoring, corrective measures, verifications and records were established. Implementing the HACCP system during preparing filling cream can effectively ensure safety of this product and other food products contained filling cram especially bakeries.
