Sc. in Agricultural Science (Agricultural Economics): Department of Agricultural Economics, Faculty of Agriculture, Ain Shams University, 2020. _______________________________________________________________________________________________ This study focuses on the evolution of urban encroachment on arable land in Egypt. There are three forms of encroachment on arable land. The first type is the removal of the fertile topsoil of agricultural land for the main purpose of bricks manufacturing. The second type is the setting aside of arable land and letting the land go unproductive for long time periods. The third type is the permanent conversion of arable land to buildings. The total acreage lost to encroachment from January 25, 2011 revolution till November 18, 2018 is about 85 thousands feddans of fertile land. The first type of topsoil removal constitutes 7.7 percent of the total lost acreage. While setting aside of arable land constitutes 35.5 percent and the conversion of arable land to buildings constitutes 57.8 percent of total land lost to encroachment. Rapid population growth is the main driver for accelerating encroachment on arable land in Egypt. This is especially evident in the governorates that are not endowed with desert backyard. Gharbeya governorate is a good example of densely populated regions with no desert backyard that could be used for urban expansion. The study reveals that population in Gharbeya grew during the period 2006-2017 with an annually rate of 2.1 percent. _______________________________________________________________________________________________

Sc. in Agricultural Science (Agricultural Economics): Department of Agricultural Economics, Faculty of Agriculture, Ain Shams University, 2020. _______________________________________________________________________________________________ There are large quantities of agricultural wastes available annually in Egypt - economically unexploited agricultural by-products, the most important of which are hay, rice straw, wood and green thrones.These can be used as animal feeds after mechanical, chemical or biological treatments to increase their nutritional valueEspecially since most of these residues are low in crude protein and high in fiber and cellulosic substances that decrease digestion and palatability when feeding animals without any treatment.It is estimated that the total amount of agricultural residues in Egypt ranges from 13-15 million tons per year, although there is a deficit in coarse feed estimated at 4.5 million tons and aims to develop livestock in Egypt to eliminate the current gap in animal products,Average annual per capita consumption of domestic livestock products is estimated at about 12 kg of red meat, 8.6 kg of poultry meat, 10.2 kg of fish, 71.9 kg of milk and 3.9 kilograms of eggs according to 2016 estimates, well below the average consumption in many developing countriesThe lack of feed resources is a major constraint to the development of livestock in Egypt, where it is estimated that the balance of feed (the relationship between feed needs and available feed resources) that Egypt suffers an annual shortage of about 3.5 million tons of digested food T. D.N, Poultry and animals, the cost of the state about 13.7 billion poundsTherefore, about 6.8 million tons of maize were imported in 2015 to be used in the manufacture of feedstuffs. It is estimated that the value of animal production requirements is estimated at 68 billion pounds, representing about 72% of the total value of agricultural production requirements estimated at 94.6 billion. Pounds,This leads to an increase in the cost of local resources as a result of the high prices of livestock inputs.This leads to the contraction of domestic supply in light of the liberalization of foreign trade as a result of the competition of imported meat, where increasing quantities of imported red meat for low prices, as previous studies indicate the relative importance of the costs of feeding dairy animals, which represents about 72% of the average total. _______________________________________________________________________________________________

_______________________________________________________________________________________________ • M. Sc. in Agricultural Science (Agricultural Economics): Department of Agricultural Economics, Faculty of Agriculture, Mansoura University, 2019. _______________________________________________________________________________________________ The encroachments on agricultural lands in Damietta governorate during the period (2003-2017) amounted to about 75885 with an area of encroachments amounting to 4043acres, which took an increasing trend, especially after the January 2011 revolution. This study mainly aimed to study the economic effects of the encroachments on agricultural lands in Damietta governorate. By studying the current situation of the phenomenon of encroachment on agricultural lands and determining the size of the deducted areas in the Republic and Damietta Governorate, determining the relative importance of the infringed areas in the Republic and Damietta Governorate during the period before the January 2011 revolution compared to the period after it. This is in order to identify the causes of the phenomenon of encroachment on agricultural lands and the economic implications of it in Damietta Governorate during the period (2003-2017) The study showed that there is an increase in the amount of loss in both total production, total income, net revenue and workers' wages for winter and summer crops. It also showed that the total value of the estimated deficit in the agricultural trade balance for both winter and summer crops together during the post-revolution period represents more than twice the value of the estimated deficit during The pre-revolution period, while the loss of livestock after the revolution was more than double the loss before the revolution, in addition to the high costs needed to reclaim new lands to compensate for that loss. And by studying the economic indicators of agricultural land use in plant production and agricultural and non-agricultural projects with the sample of the field study in Damietta governorate for the year 2016, it became clear that the net return achieved and the net return on the pound for most of the non-agricultural projects from carpentry workshops and furniture paint in addition to animal production projects from fattening, production and poultry farming It has far exceeded the net achieved and the net return on the pound through the cultivation of the vegetable production cycle (alfalfa + cotton), and this is what prompted many farmers to deduct areas of their lands and The study reached several recommendations, the most important of which is making use of pickles in Egyptian villages and permitting building on them, encouraging farmers to use their land for agriculture only, through the Egyptian state providing all agricultural supplies at reduced prices and helping them market their agricultural crops at high prices in order to achieve a greater return for them than any project. else. _______________________________________________________________________________________________

The experiments were conducted in Fish Research Center - Suez Canal University: The present study was designed to evaluate the use of spirulina (Spirulina platens is) as a replacement of protein with different levels from protein diet for fingerlings Nile tilapia (Oreochromis niloticus). Spirulina was incorporated into tive isonitrogenous and isocaloric diets At 0, 5, 10, 15 and 20% of the protein - based diet. The test diets were fed to the fishat satiation twice a day for 56 days. The final weight gain, specific growth rate, feed conversion ratio, feed efficiency, feed intake, protein efficiency ratio and survival rate of fish significantly (p<0.05) higher for group of fish replaced with 20% Spirulina platensis (T5) and decreased gradually at T4 ,T3,T2 and Tl respectively. There was a significant difference in protein and lipid in carcass proximate composition of the fish fed on 20% spirulina diets as compared to those on the rest of experimental groups. These results suggest an improvement of fish health when fed with feed replacement, Moreover, fish fed with diets containing different spirulina levels exhibited higher total protein serum Creatinine, Urea, Albumin, Globulin, Triglycerides, HDL-C values. On contrary, significantly decreased Albumin Iglobulin Ratio, LDL-C, AL T and AST values compared with control as increased of Spirulina levels. The highest values were obtained at T5 diet. This study demonstrates that up to 20% of spirulina replacement from soybean protein was most effective in stimulating fish growth and more economic for Nile tilapia (Oreochromis niloticus) fingerlings under this experimental condition. Key Words Spirulina platensis, replacement, Nile Tilapia fingerlings, growth performance, feed utilization, carcass composition.

_______________________________________________________________________________________________ • M. Sc. in Agricultural Science (Agricultural Economics): Department of Agricultural Economics, Faculty of Agriculture, ElMansoura University, 2016. _______________________________________________________________________________________________ Egypt has suffered from lack of current water resources to achieve its needs especially because of Egypt's seeking to increase agricultural lands in addition to regional challenges which Egypt faces with Nile countries. The agriculture sector is one of the most important sectors that consumes water. It consumes about more than 80% of the available water resources. Kafr El-Sheikh is one of north Delta governorates which is facing a shortfall in water resources because most of its territories are at the ends of the main canals. So it depends on the agricultural drainage water to balance between needs and water resources by mixing the agricultural drainage water with water canals. For these reasons, the research paper aims mainly at achieving, The economic efficiency effect of using kinds of water irrigation on the Rice Production under the affect of using the fresh water, darning water, and waste water in the agricultural sector. Qualitative and quantitative methods were utilized to achieve the study purpose. Such as, ANOVA, Least Significant Deference(L.S.D.), The Deterministic Frontier Approach, using Data Envelopment Analysis (DEA) to estimate economic efficiency. The study included six chapters: The first chapter has dealt with the literature review and research frame work, the second chapter has concerned with the current and future situation of water and land resources in Egypt, the third chapter has dealt with the current situation of the most important crops in Egypt especially in Kafr El-Sheikh , while the fourth chapter studied the sample of field study, the fifth chapter has concerned with the economic analysis of using different kinds Of water irrigation impact on the economic indicators of the most important crops, in addition to the six chapter which has concerned with measuring estimation of using different kinds Of water irrigation effect on economic efficiency of the most important crops. The study also included an Arabic and an English summaries, in addition to Arabic and foreign references. The study reveals the following results: 1. . Nile water contribution to the offered quantity of water has decreased from about 82.52% in 2000-2001 to about 73.03% in 2013-2014, while the the quantity of of agricultural drainage water has risen from about 8.43% to about 14.61% during the same period. 2. The available water resources of the agricultural sector has increased by about 0.567 billion m3, equivalent to approximately 0.95% per year while the terrestrial unity share of water resources has reached about 7030 m3 during the same period. The terrestrial unity share of drainage water has increased from about 530 m 3 in 2000, to about 1406 m 3 in 2013. 3. It is expected to increase agricultural drainage water from about 12.09 billion m3 in 2018, for about 13.79 billion m3 in 2020, as well as wastewater from about 1.33 billion m3, for about 1.36 billion m 3. It is also expected to increase agricultural water uses from about 63.95 billion m3, for about 64.59 billion m3 during the same period. 4. Production capacity of sugar beet in Kafr El-Sheikh represents about 41.24% of republic production of the while rice represents about 9.71% of Republic production . 5. Productivity of sugar beet crop reaches about 23.87, 22.11, 20.84 tons / acre in fresh water irrigation, mixed water, agricultural drainage water respectively. Total revenue reaches about 9170, 9709.8353 pounds / acre respectively. Net return reaches about 3442 acres, 2871.2179 pounds / acre. Profit reaches about 0.55, 0.46, 0.35 pound respectively. Unit water productivity reaches about 11.37 10.53, 9.92 tons per unit of water, and the amount of water to produce a unit reaches about 95, 101 and 88 m 3 respectively. The net return per unit of water reaches about 1376.1639, 1038 pounds / acre respectively. 6. Productivity of rice crop reaches about 4.00, 3.01, 2.77 tons / acre freshwater irrigation, water mixed, agricultural drainage water, respectively. In addition to that there are significant differences between the irrigation quality of fresh water and mixed water, and between fresh and drainage water, while there is no significant difference between the mixed and drainage water in any familiar significant levels. This reflects that fresh water is the best one for the rice crop. Total revenue reaches about 7757, 5778, 5303 pounds / acre, respectively, and a net acre return reaches about 2716, 655, 471 pounds / acre for each of them, respectively.

The aim of the present study was to evaluate the effects of GH gene polymorphisms on reproduction and growth traits and identify its variability in the rabbits. A total of 218 blood samples collected from rabbits were used to evaluate the allele frequency distribution for GH gene polymorphisms and its association with reproductive and growth traits in rabbits. The samples included 16 rabbits of the different breeds (Middle-Egypt native breed, Gabali Sinai, Baladi Black, Baladi Red and New Zealand White) and 202 rabbits (118 female and 84 male) from APRI rabbits. The traits tested were: (1) body weight (BW) at 5, 6, 8,10 and 12 weeks from birth, (2) daily bodyweight gain (DBG), (3) reproductive traits included age at puberty (AP), Kindling interval (KI), litter size at birth (LS), litter weight (LW) at birth, Litter size at weaning (LSW) and litter weaning (LWW), (4) milk yield. For this purpose, DNA was extracted from rabbit blood samples and used in PCR amplification. The c.-78C >T SNP was genotyped by PCR-RFLP using the digestion by restriction enzyme Bsh1236I (BstUI). Association analysis between the GH C >T SNP and body weight, growth and reproductive traits was tested in the rabbits population using SAS program. The heterozygous genotype was associated with heavy weight of rabbits in different ages during the growth period. This increase in weight was significant (P < 0.05) at 8 weeks of age. DBG through 5-8 week interval was significantly associated (P < 0.05) with the T/C genotype. The heterozygous genotype (T/C) exhibited higher values in the DG compared to C/C and T/T genotypes. The estimated dominant genetic effect (d) was significant (P < 0.05) in 8 weeks. The C/C genotype showed significant value (P<0.05) associated with early age of puberty. The estimated additive genetic effect (a) and estimated dominant genetic effect (d) in a population was insignificantly associated (P<0.05) within all the investigated reproductive traits in rabbits. Polymorphism of heterozygous genotype T/C was associated with milk yield traits of rabbits during the first two weeks in suckling period. Estimated additive genetic effect (a) in a population was significant (P<0.05) within milk yield at the second week of suckling period of rabbits. Estimated dominant genetic effect (d) was significant (P < 0.05) within milk yield at the first week of suckling period of rabbits. In conclusion, the polymorphism of growth hormone (GH) gene in rabbits may has over dominance at the locus c.-78C >T. Positive effects of the heterozygous genotype were recorded compared to both homozygous genotypes on body weight, body gain and milk yield at the first two week. The effect of the C allele of GH gene decreased the age of puberty in rabbits. Effects of the heterozygous genotype in c.-78C > T of GH polymorphisms on the tested traits in current study and on the fmishing weight in previous study could be selected as a favorable genotype in rabbits and may be used in Marker-assisted selection (MAS) programs to improve growth performances rabbits. Key words: Rabbit, GH , association study SNP , reproductive, growth traits.
