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.

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.

In this study the plant by-products and the waste of some food processing or farm land wastes are very rich in the natural antioxidants. There for the aim of this study was to investigate the utilization of these compounds in protection or prevention of some human diseases. The present study was conducted to studying the effect of the polyphenols compounds extracted from dried (Artichoke leaf, Olives leaf and Red grape seeds) on some liver diseases. The main objective of this study is Comparison between the extraction solvents (water – ethanol) on the total content and the polyphenols fractions of (Artichoke leaf, Olives leaf and Red grape seeds) determine by HPLC. Effect of adding the polyphenols water extract of the above three materials on the cooking quality and sensory evaluation of the (paste) as a function food. Effect of adding these paste to the diet of the adult mail albino rats treated with carbon tetrachloride (CCl4) induced liver damage. It can be observed that , ethanol was the more effective solvent for extraction of poly phenols than water, where the ethanol extract contain phenol fractions higher than the water extract in both artichoke and olive leaves as well as ethanol extract showed high concentrate of the total phenolic compounds identified compared with those of water extract. Where artichoke, olive leaves and red grape seeds recorded 712.95, 235.19 and 463.38 for ethanolic extract compound with 426.5, 127.11 and 51.89 mg/100 g for the water extract, respectively. Finally, the results obtained from the biochemical analysis of the rats serum and histopathological examination of the liver refer to a marked improvement in the health status of the rats after administration the water extracts of the artichoke, olive leaves and red grape seeds. However, this study could not determine which of these extracts the better is. we suggest further studies with a focus on the extraction methods, doses used and experimental period Key words: Waste, By-products, Artichoke leaves, Olive leafs, Red grape seeds, Polyphenols, Liver diseases, CCl4.

Ten compost treatments were prepared by mixing rice straw with some different addi¬tives. Treatments were arranged in piles ac¬cording to the component of each pile. Initial temperature in all treatments at zero time was 21°C. During the following days considerable variations in temperature were observed in different treatments. The 10 treatments exhib¬ited two groups according to temperature's demeanor. The first group comprises the treatments 1, 2, 3, 4, 5 and 6 which were pre¬pared without addition of cattle dung. The temperature of the mesophilic initial phase of composting process were ranged approxi¬mately from 21 to 45 °C and takes from 9 to 15 days. In the thermophilic phase the tem¬peratures were increased gradually to reach a maximum temperature ranged between 50 and 62°C. The second group comprises the treatments 7, 8, 9 and 10 which were pre¬pared by addition of cattle dung. The temper¬ature of initial mesophilic phase ware ranged from 21 to36°C and takes three days. The thermophilic phase w-?s continued from 35-40 days and the highest temperature degree was reached to 65-67°C. Variations in temperature during composting process lead to succes¬sion of different microbial communities. Dur¬ing the initial phase of composting process the counts of mesophilic microorganisms were increased. As a result of increasing temperature the counts of mesophilic organ¬isms were reduced and the counts of thermo¬philic organisms were increased. While up to the end of compost process the temperature was reduced with resultant reduction in the counts of thermophilic microorganisms and dominating the mesophilic microorganisms in the process. The total and fecal coliform as well as other pathogenic bacteria {Salmonella and Shigella) were not detected in the fin¬ished products

The aim of this study is to produce compost using rice straw as raw material. Ten treatments were prepared by adjusting the C/N ratio of the rice straw either by addition cattle dung or ammonium sulphate. The mixtures were supplemented with phosphate and potassium either in organic or inorganic forms. The effect of addition of bio-accelerator as the fungal inoculant that consisted of dual cultures of Trichoderma harzianum NRRL 13019 and Phanerochaete chrysosporium NRRL 6359 was also considered. Another set of the same 10 treatments was prepared by adding Eisenia fetida after the thermophilic phase i.e when the temperature steadily reached 30 oC. The earthworms were added to each of the plastic bin, which containing the pre-composted materials. The composting process was continued in both sets up to 16 weeks. Tea was prepared using compost and vermicompost which were produced from the best four treatments. A pot experiment was carried out under greenhouse conditions, during the growth seasons of January 2011. This experiment was designed to study the effect of addition of compost, vermicompost, compost tea and vermicompost tea, produced from the best selected treatments on the growth of common sage (Salvia officinalis L.). The growth was measured in terms of fresh and dry weights (g / plant). The essential oil percentage, total N, P and k percentages were also determined at the end of each cut. Results were statistically analyzed. The obtained results revealed that the plants of common sage (Salvia officinalis L.) which were treated with vermicompost of rice straw, supplemented with cattle dung, rock phosphate, feldspar and fungal bio-accelerator (treatment no. 7) showed their highest values of shoots fresh and dry weight, oil, N, P, K% compared with the other tested treatments.

The experiment was designed to evaluate the use of antibiotics Alternatives and some vaccination programs by using hyperimmunized egg yolk in broiler chicks. 500 one day old Hubbard and cobb broiler chicks were used. They were divided into four groups; the first group is the control one, the second group was injected egg yolk containing immunoglobulin which type (Ig) against (NDV), IBDV and alternative antimicrobial agents to poultry production and processing. Bacteriocins are proteinaceous compounds of bacterial origin that are lethal to bacteria other than the producing strain within tow strain of broilers. The present results showed that the broiler chicks injected egg yolk containing immunoglobulin against IBDV, NDV and combination recorded the highest hemoglobin and hematocrit level compared to control group. Similar trend was noticed for white blood cells count. However, there was no significant difference among treated groups for red blood cells count. With respect to the changes in lymphoid organs weight, the present results showed that the relative bursa weight was significantly decreased in a group injected with egg yolk containing immunoglobulin against IBDV + NDV compared to control group. The groups that are injected with egg yolk containing Ig against IBDV or NDV had significantly higher relative thymus weight compared to other groups. There was no significant difference among the treated groups for antibody titer against both NDVand IBDV. Key words: Broiler, NDV, IBDV, Immunoglobulin
