  : Six Rahmani rams and 26 mature ewes were used in this work kept at Suez Canal University Experimental Farm. The Rahmani rams aged 12 months at the beginning with an average live body weight 45.00 ±1.80 kg. The six rams were divided into two equal groups (A and B). Group A was fed concentrate mixture ad lib while group B received only 80 % of the ad lib concentrate mixture. The roughage, ammoniated rice straw (3 %) was fed ad lib for the two groups during experimental period. Two successive semen ejaculates were collected weekly from the rams of the two groups and evaluated, after a period of ten weeks has elapsed in training for semen collection from these rams. Semen evaluation included the physical characteristics and the two indices of sperm metabolism which were methylene blue reduction time (MBRT) test and fructolysis index. The results of this experiment showed that semen ejaculates collected from rams of group A had slightly better physical characteristics than those of group B. MBRT showed the same trend. It was 74.39±2.69 sec., for group A and 80.72±3.12 sec. for group B. Fructolysis index after 60 min. of semen collection was 1.61±0.12 / 109 motile sperm for group A and 1.42±0.11 /109 motile sperm for group B. while it was after 60 minutes of frozen and thawing 1.91±0.14 for group A and 1.93±0.27 / 109 motile sperm for group B. Conception rate of ewes which were inseminated with frozen thawed semen of group A was 57.14 % (8/14) and was 50% (6/12) in ewes that inseminated with frozen thawed semen of group B. The difference between the two groups was insignificant. It could be concluded that restriction of feeding rams 20% of ad lib of the concentrate mixture had not affected the rate of the metabolism of the spermatozoa of group B.

  Six Zaraibi goat bucks aged ten months with an average live body weight 31.17±1.78 kg were used. The animals were divided into two equal groups A and B. Group A was fed 100 % ad lib and group B was fed 80 % ad lib of the concentrate mixture. The roughage ammoniated rice straw was fed ad lib for the two groups. Two successive semen ejaculates were collected from each buck weekly after ten weeks of starting feeding of two planes to group A and B. A total of 178 semen ejaculates were obtained through the period of this experiment. Results showed that semen ejaculate collected from bucks of group A were of slightly better physical semen characteristics than that collected from bucks of group B. Methylene blue reduction time test (MBRT) of group B was 91.00 ±4.89 sec. while it was 97.81±7.01 sec. for semen ejaculates of bucks of group A which gave semen ejaculates of lower sperm concentration (109/ml) as compared to that obtained from group B. the differences between the two groups in the physical semen characteristics were statistically insignificant except for sperm concentration (109/ml) semen. First semen ejaculates of the bucks of the two groups showed also slightly better physical characteristics than second ones. Methylene blue reduction time test showed the same trend and it was 81.58±4.75sec. and 94.70±5.55 sec. for the first and the second semen ejaculates, respectively. Fructolysis index of raw semen of bucks of group A was of higher value (1.53±0.09 mg / 109motile sperm) than that of bucks of group B (1.38±0.11 mg / 109 motile sperm). Fructolysis index after freezing and thawing showed the same trend of the previous studies on rams spermatozoa. Fructolysis index for bucks of group A & B after freezing and thawing was 1.85±0.39 mg /109 motile sperm and 1.48±0.16 mg/109motile sperm, respectively. The difference between the two groups was statistically insignificant. It could be concluded that restriction of feeding Zaraibi bucks 20 % of ad –lib of the concentrate mixture had not affected significantly the semen characteristics and sperm metabolism of goat buck sperm cell.

  The growth response of S. persica in vitro via micropropagation using nodal cutting explants was investigated. The effect of kinetin, indole acetic acid and type of nutrient medium on the growth of nodal cutting cultured in vitro after 8 weeks in starting stage was studied. The influence of kinetin, indole acetic acid treatments and their combination on the Murashige and Skoog (MS) basal medium full strength was determined in the multiplication stage. The highest rooting percentage was obtained on MS medium supplemented with 2.0 mg/l Indole acetic acid without addition of active charcoal. Preliminary phytochemical screening identifies the presence of carbohydrates and/or glycosides, free flavonoids, sterols and/or triterpenes, alkaloids as well as tannins more strongly in the shoot samples propagated from tissue culture technique indicating their occurrence in such samples with higher amounts. The UV and the visible spectra were recorded by the spectrophotometer for the tested extracts prepared from both the wild and tissue culture propagated plant of S. persica. The UV/visible spectra of the ethanol 95% extracts of both the wild and tissue culture propagated plant were similar. The intensities of the absorption bands were higher with the extracts prepared from the plant propagated by tissue culture technique. The extracts of S. persica propagated by tissue culture technique exhibited a broad spectrum antimicrobial activity against the tested microorganisms, meanwhile the extracts of the wild plant showed less activity.

  White rot disease is important disease which attack bean causing great losses in quality and reduced the total quantities yield. Some factors which affecting the disease incidence were investigated as well as different methods of pathogenicity as well as effect of culture filtrates of the different isolates on the germination of bean seeds. athogenicity test of S. sclerotiorum using stem inoculation technique on cv. Paulista showed that all tested isolates of S. sclerotiorum differed in their virulent. There are a correlation between the length of the lesions on the stem and their pathogenicity. On the other hand, the best method for soil infestation was adding the sclerotia to soil, followed by the soil applying with mycelium on wheat kernels. While the lowest method for soil infestation was the soil infested with the mycelium. The symptoms need 24 hours to appear on the leaves. At the same time, there are a positive correlation between the time of inoculation and the lesions length. A positive correlation between the time of inoculation and the pods rot (cm). On the other hand, all isolates produced different numbers of the sclerotia on the pods after 10 days from the inoculation except isolates ScE2 and ScE8 did not produce sclerotia on the pods. All culture filtrates of the different isolates significantly reduced the percentage of bean seeds germination and length of radical roots compared with the untreated seeds.

  Organophosphorus compounds -via gavage
  Organophosphorus compounds are widely used in industry, agriculture and for public health purposes. They are among the toxic compounds employed for insect control. The purpose of this work was to study biochemical and histopathological changes in liver and kidney of rats as a result of intoxication with profenofos. The treated groups received profenofos orally via gavage at doses of 0.67, 1.012, 1.51, 2.27, 3.405 mg/kg b. wt every other day for 10 days while the control group was given corn oil only. Biochemical indices in serum [alanine aminotransferase (ALT), aspartate aminotransferase (AST), glucose, bilirubin, uric acid and creatinine] were significantly elevated while cholinesterase activity decreased significantly in treated rats in comparison with the control group. Serum urea levels were not changed with the dose increase. Biochemical results were supported by the histopathological picture of liver and kidney. Tissues damages were correlated to the dose increase. Liver sections showed necrosis of hepatic cells as well as the presence of some inflammatory cells besides hyperplasia of bile duct. Kidney specimens showed swelling of tubular epithelial, hemorrhage, mononuclear cell infiltration and lymphocytic infiltration. These findings show that exposure to profenofos insecticide has a clear toxic effect on the rat liver and kidney. Public health education is necessary to raise people awareness about the hazards accompanying the use of such compounds.

  Body condition score, milk production, additive correlation, repeated measurements
  The objectives of the present study were to describe the relationships between repeated body condition scores across different levels of daily milk production. Body condition scores from producer and consultant-recorded data were available across different stages of lactation across the first three parities. Additive genetic correlations between repeated measures of BCS across different levels of daily milk production were high and ranging from0.79 to 0.98 within the 1st lactation. The lowest additive relationship occurred within the 2nd and the 3rd lactation between BCS at the lowest and at the highest milk production level. Permanent environmental correlations between repeated BCS are in reduction mode with increasing the distance between levels of daily milk production within all studied parities. BCS within the 1st and the 3rd parity are in strongly additive genetic relationship at the similar level of milk production. While the corresponding estimates between the 1st and the 2nd parities are low to moderate. In general if accurate genetic evaluations for BCS are to be obtained, recording the date of BCS evaluation should be considered in different breeding programs for improving the total benefit of dairy cattle projects.

  sunflower cultivars, drought, anatomical structures
  A field experiment was performed, during the summer season of 2007 to study the effect of four irrigation intervals, i.e. 4, 8, 12 and 16 days on root and leaf structures of sunflower (Helianthus annuus L.). Sunflower cultivars viz., Sakha 53 and Giza 102, were grown to maturity in a sandy soil. Extending the irrigation interval (drought) increased xylem arm length and average number of xylem vessels bundle-1 in the root. However, an opposite trend was observed true with epidermis thickness, cortex thickness, and average row number of cortex and thickness of biggest xylem vessel. In the cross sections of root the effect on Sakha 53 cultivar was more significant than that with Giza 102 cultivar in all studied characters. Extending the irrigation interval (drought) increased some anatomical characters of leaf such as the thickness of upper epidermis+ palisade tissue, lower epidermis+ spongy tissue, average number of xylem arms bundle -1 and number of xylem vessels bundle -1. Concerning the cultivar effect, Sakha 53 significantly excelled Giza 102 for the thickness of each of mesophyll, upper epidermis + palisade tissue and collenchymatous tissue lower vascular bundle. But the reverse was correct with the thickness of collenchymatous tissue upper vascular bundle and number of xylem arms bundle in leaves.

  Two pots experiments were conducted during 2006 and 2007 seasons to study the influence of four levels of salinity (325 control, 1000, 2000 and 3000 mgl-1) of sunflower (Helianthus annuus L.). Sunflower cultivars viz., Sakha 53 and Giza 102, were grown to maturity in a sandy soil (ECe 2.1 dSm-1). Raising the level of water salinity reduced the yield parameters including diameter of achene, number of seeds achene-1, weight of 100 seeds, seed yield plant -1, total oil and total protein content plant-1. The differences between the two cultivars were not significant in most yield parameters during the two growing seasons (2006, 2007). However, Sakha 53 cultivar was more tolerant than Giza 102 cultivar. The higher salinity level up to 3000 mgl-1, the severer was its depressive effect on the studied yield components.

  Tomato concentrate, Egyptian and Yemeni standards, chemical composition, rheological properties, quality control, color, lycopene, carotenoids, pectin.
  The present study deals with some quality attributes of the tomato concentrate (paste or puree) marketed in Egypt and Yemen under different brands. The impetus behind the present study was the numerous beneficial effects that could be gained from tomato concentrate (paste or puree). The whole work was conducted according to the Egyptian and Yemeni standards. The results of chemical and microbiological determinations showed some or great variations between the tested Egyptian and Yemeni tomato concentrate brands. Therefore, serious control on the quality of tomato concentrate is required. There were a well positive correlations between rheological properties especially, apparent viscosity and total pectin contents. There was a good correlations between Hunter color readings and a*/b* ratio of the samples and concentrations of lycopene and total carotenoids. The effect of temperature on viscosity was very well correlated with the Arrhenius equation (R2 > 0.90).

  The sedentary endoparasitic root-knot nematode [ RKN ], Meloidogyne incognita ( Kofoid and White ) Chitwood, is worldwide an economically important agri-pest, reducing the yield and quality of crops. The traditional method of RKN control is based mainly on chemical nematicides, which will not be frequently available from last decade onwards; their use is highly objectionable due to their major contribution to ground water contamination and dangers to the environment and to human and animal health. In a glasshouse in pot trial, dried leaves of eight wild plants in comparison with oxamyl were evaluated against M. incognita infecting olive cv. Picual. Powdered leaves were used at 5, 10 and 20 gm/kg soil, while oxamyl was applied at 4, 8 and 16 ppm. Results revealed that incorporation of dried leaves of the tested plants and oxamyl reduced galling and reproduction of M. incognita compared to plants free from any amendments. This reduction was varied according to wild plant species and rate of application. The wild plant H. elegans at three applied concentrations proved to be more effective in controlling M. incognita. Number of galls, egg-masses and juveniles for H. elegans at the lowest conc. ( 5gm/kg soil ) were 38.33, 9.33 and 220 respectively, while at the highest cons. ( 20 gm/kg soil ) completely eliminated galls, egg-masses and juveniles. On the other hand, C. colocynthis gave good results in reducing galling and reproduction, since number of galls, egg-masses and juveniles at the three conc. did not differ significantly with those obtained with oxamyl. Other tested plants showed a relatively median effect in decreasing galling and reproduction of M. incognita. Also general mean of the three conc. for each treatment was calculated and the nematicidal efficiency based on percent reduction in galling and reproduction was separately estimated in relation to the parallel values of untreated plants. It was clear that H. elegans has the upper hand, followed descendingly by oxamyl at ppm range, C. colocynthis and A. santalina. from all what mentioned it could be concluded that there is a promising possibility of using an ecofriendly effective alternatives or non chemical pest management systems for achieving a sustainable agricultural practices.

Also the applicable & alternative methods for treatment of waste water dealing with aphysiochemical consideration of the properties. The results indicated that the Total Soulble Solids(T.S.S), Volatile Soulble Solids(V.S.S),Fixed Solids (F.X), Chemical Oxygen Demand(COD) and Biological Oxygen Demand after 5 days)(BOD5)were more significantly higher in continuous mills than in traditional mills , but the value of (T.ph.s)Total polyphenols was slightly higher in continuous mills than in those traditional mills, the use of (PAC) powdered activated carbon achieved a highly significant removal % of T.ph.s,T.S.S,V.S.S,F.S,COD&BOD5 arranged in a descending order as in the following:60%,50%,50%,50%,43%&22% respectively. In case of treatment with a mixture of (2:1)% of (NaOH+Na2CO3),the percent of removal of T.ph.s,T.S.S,V.S.S, F.S,BOD5&COD were highly significant&arranged in a descending order as in the following:60%,40%,40%,40%,30%&25% respectively.And by using a mixture of (NaOH+Na2CO3) at a rate of (3:1) proved a more highly significant removal for the T.ph.s,T.S.S,V.S.S,F.S,BOD5&COD.These values of removal were arranged in a descending order as in following:75%,50%,50%,50%,47%&40% respectively.The use of FeSO4.7H2O was more effective in lowering the values of T.S.S,V.S.S&T.ph.s than FeCl3.6H2O &were arranged in a descending order :40%,40%&30% respectively .While the use of FeCl3.6H2O was too more effective in decreasing value of F.S,COD and BOD5 68%,50% & 30% respectively. Also it can be mentioned that the increase of H2O2 concentration to 5 ml at 2.5 gm of FeSo4 improved organic matter degradation ,however excessive amounts of oxidant to 10 ml has no or even a slight adverse effect on performance due to H2O2 induced radical scavenging.It is very common that the national & international goal for the control of water pollution is the elimination of pollutants discharge into navigable waters.Also the industry improvements often finds that it is more economic to treat waste water for reuse than discharge into Environment.

  cattle, vegetative growth, sandy soil, Verbascum thapsus L.
  Three culture spacings at 20, 30 and 40 cm between the plants in row and three rates of cattle manure at 0.0, 30 and 45 m³/fed. were used to study the effect of culture spacings, cattle manure levels and their interaction on the growth and active ingredients of Verbascum thapsus L. (mullein). Data were recorded on growth, dry leaves and flowers yields as well as some active ingredients. Generally, the highest yield of dry leaves and flowers as well as the highest contents of total iridoid glycosides, total saponins and total mucilages/plant in leaves and flowers were obtained from using the widest plant spacing (40cm) and the highest level of cattle manure (45m³/fed.) each alone or in combination. However, the highest yield of dry leaves and flowers as well as the active components/fed. were produced with the narrow spacing (20 cm) alone or in combination with the highest level of cattle manure (45 m³/fed.) in both seasons.

  NPK fertilization, plant spacings, vegetative growth, sandy soil conditions, Verbascum thapsus L.
  The present work aimed to study the effects of plant spacings, NPK fertilization levels and their interaction on vegetative growth, flowering and some active ingredients of common mullein (Verbascum thapsus L.) plants under sandy soils conditions. Three spacings at 20, 30 and 40 cm between the plants in row and four levels of NPK fertilization at 0.0:0.0:0.0, 20.5:15.5:24, 41:31:48, and 61.5:46.5:72 kg/fed. of N: P2O5: K2O, respectively were applied. Generally, the highest yield of dry leaves and dry flowers per plant as well as the highest content of some active components in leaves and flowers (total iridoid glycosides, total saponins and total mucilages) were obtained from using the highest levels of each of plant spacing and NPK fertilization alone or in combination. Whereas, the highest yields of dry leaves and dry flowers per feddan as well as the active components were produced with the narrow spacing (20) cm combined with the highest level of NPK fertilization in both seasons.
