This study was carried out to determine the effects of different levels of mannan and β-glucan as a prebiotics on some liver and kidney function, blood parameters, immune globulins concentration and body weight on broilers fed diets contaminated with 1mg aflatoxin / kg diet. Eighty broilers were randomly distributed into eight similar groups each group fed commercial broilerdiet as the follows {negative control group fed an regular broilers ration free from prebiotics and aflatoxin, posative control group fed diet contaminated with aflatoxin (1mg/kg) and free from prebiotics, groups from 3 to 8 fed diet contaminated with aflatoxin (1mg/kg) and contain different concentration of mannan and β-glucan in premix (premix added as a 1.5 gm/kg diet)}. Results showed that positive control significantly increased (P < 0.05)serum glutamic-oxaloacetic transaminase (SGOT) and serum glutamic-pyruvic transaminase (SGPT), compared with negative control and the best effect of adding mannan and β-glucan recorded with group 5, 6 where the results were close of negative control. The same trend recorded with results obtained from serum urea andcreatinine. Results of hematological analysis showed that positive control caused a significant decrease (P < 0.05)in values of packed cell volume (PCV), Red blood cells counts (RBC), Hemoglobin (Hb), and noticed a significant increase (P < 0.05) occurrence in values of total white blood cell (WBC). Generally the addition of mannan and β-glucan to diets contaminated with aflatoxin significantly improved the adverse effects of aflatoxin on hematological parameters. This study demonstrates an increase in serum IgGs concentrations with positive control and group8 without significant differences with negative control or other groups. The average body weight gain (g) increased (P < 0.05) with broilers fed negative control diet compared with positive control. The addition of both mannan and β-glucan to diets led to improvement in increase body weight gain and decreases in relative liver whight ratio.

Two field experiments were conducted during the period from 2009/2010 winter season to 2013 summer season to investigate the response of maize (cv. Giza 10) to twelve preceding crop sequences, differing in legumes to non-legumes ratios and terminal crop, under 252, 288 and 324 kg N/ha. Maize traits, i.e. plant height, ear leaf area, leaf area index, ear grain weight, 100-grain weight and grain yield/ha, responded significantly to crop sequences. They were increased with increase of legumes percent in crop sequence and proximity of legume crop to maize. The 100 % legume sequence gave the maximum values for such traits whereas the least values resulted from crop sequence containing legumes of 40 % and terminated with wheat. Differences between N levels, regarding plant height, ear leaf area, leaf area index, ear grain weight, 100-grain weight and grain yield/ha, were significant, indicating the superiority of 324 kg N/ha compared to 252 and 288 kg N/ha. The interaction effect of both crop sequences and N application levels was significant for plant height, ear grain weight, 100-grain weight and grain yield/ha in both seasons, where the highest values of these traits were obtained from 100 % legume sequences and application of 324 kg N/ha. The regression analysis, in both seasons revealed that the linear effect was significant, while the quadratic effect was insignificant regarding number of grains/ear, 100-grain weight and grain yield/ha. That implies the possibility of increasing N level up to 324 kg N/ha to attain maize characters of higher values.

Mozzarella cheeses prepared from buffalo, cow and their mixture (1:1) using commercially available starter cultures (Streptococcus. thermophilus and Lactobacillus. bulgaricus)(1:1). Resultant cheeses were examined when fresh and during storage period at 5 ±10C for 4 weeks. The cow milk Mozzarella cheese tended to be softer, slightly better in flexibility and contained slightly higher moisture, fat and salt contents whereas buffalo milk Mozzarella cheese had higher protein content. Cheeses were also evaluated for meltability (to assess the functionality of cooked cheeses), stretchability, oiling off, microstructure and organoleptic quality. Mozzarella cheese made from buffalo milk showed lower contents of soluble nitrogen and total volatile fatty acids than cheese made from other milks. The electrophoretic pattern of proteins from different milk showed the presence of µs and B-casein as the major components and minor fast and slow moving products. The mobility and relative intensity of the µs-bands differs according to the type of milk. The results indicate that proteolysis in the µs-fraction occurred in all types of milk. Also cow milk cheese gained the highest score for organoleptic properties, while buffalo milk cheese showed the lowest quality. Mixing cow milk with buffalo milk highly improved the quality of the cheese.

An 7 x 7 complete diallel cross of squash was evaluated with parents for heterotic manifestation and evaluate the genetic behavior of yield and yield component traits. Seven different squash varieties belong to the species (Cucurbita pepo, L.), were used in this study. These parental varieties were: Eskandarani (P1); Zucca Patisson custard white (P2); All Green Bush (P3); Courgette Orelia (P4); Sakiz (P5); Copi (P6) and Gapla (P7). The seeds of these parental varieties were obtained from different countries: (P1) and (P6) from Egypt; (P2) from France; (P3) from United Kingdom (U.K.); (P4) from Germany; (P5) from Turkey and (P7) from Syria. These parental varieties were used and their 42 F1,1r hybrids were obtained through complete diallel crosses mating design system. Data were recorded for seven traits: fruit length (F.L.cm); fruit diameter (F.D.cm); fruit shape index (F.Sh.I.); Total Soluble Solid% (T.S.S%); weight of fruit (W.F.g); number of fruits per plant (No.F./P.) and fruit yield per plant (F.Y./P.kg). The results also indicated that the amounts of heterosis versus mid-parents showed highly significant values for all studied traits. The estimates of heterosis versus the better parent showed highly significance for most studied traits. None of the hybrids exhibited maximum heterosis for all the traits, but significant and desirable level of heterosis over mid-parents and better parent was obtained in several hybrids for the different traits. However, GCA values were larger than their corresponding estimates of SCA for studied yield and yield component traits at both F1,1r hybrids. Reciprocal effects (r) were significant for most studied traits. The results indicated that the parents P1, P3, P4, P5 and P7 were seemed to be the best combiners for fruit length (F.L.cm), fruit shape index (F.Sh.I.) and number of fruits per plant (No.F./P.). Also, P2 was the best combiner for Total Soluble Solid% (T.S.S%). In the same time, the two parents P2 and P6 were the best combiners for fruit diameter (F.D.cm) and weight of fruit (W.F.g). These results indicated that the parents P1, P2 and P4 were seemed to be the best combiners for fruit yield per plant (F.Y./P.kg). All 49 genotypes (seven parents, 21 F1's and 21 reciprocal hybrids) were evaluated in a field trial at the growing summer. The experimental design was the Randomized Complete Blocks Design (RCBD) with three replications of 2010. This study was conducted in the Kaha Research Farm of Vegetables Breeding Department, Horticultural Research Institute, (HRI), Agric. Res. Center (ARC), Giza, Egypt.

The main objectives of this investigation were to determine the amounts of heterosis versus the mid-parents and the better parent, nature of gene action and heritability in both broad and narrow senses. Seven squash varieties belong to the species (Cucurbita pepo, L.), were crossed to obtain 42 F1,1r hybrids according to a complete diallel crosses mating design. The results revealed that the mean squares of genotypes which included seven parental varieties and their F1,1r hybrids were highly significant for all vegetative traits. The results also cleared that the mean values showed that no specific parent was superior for all vegetative traits. The results indicated that the parents P1 and P6 seemed to be the best combiner for vein length (V.L.cm); number of leaves per plant (No.L./P.); leaf area (L.A.cm2); fresh weight per plant (F.W./P.g) and dry weight per plant (D.W./P.g). Meanwhile, the GCA effects were found to be significant and positive for mostvegetative traits. The parental varieties P3, P6 and P7 were the best combiners for the ratio of chlorophyll in leaves (Chl.). The estimates of heterosis versus mid-parents showed highly significant values for all studied traits. The estimates of heterosis versus better parent showed highly significant values for most vegetative traits. The results showed the importance of general and specific combining abilities. GCA was larger than their corresponding estimates of SCA for vegetative traits. Reciprocal effects (r) were significant for most studied traits. Estimation of genetic parameters showed that the additive genetic variance was very important for most studied traits. The inheritance of these traits was mostly governed by additive genetic variance rather than non-additive and cytoplasmic genetic factors. In the same time, the estimates of heritability in broad sense were larger in magnitudes than their corresponding values in narrow sense.

This study was conducted at Kaha Research Farm of Vegetables Breeding Department, Horticultural Research Institute, (HRI), Agric. Res. Center (ARC), Giza, Egypt, during the period from 2008 to 2010. The study aimed to estimate heterosis versus the mid-parents and the better parent, general (GCA) and specific (SCA) combining ability variances, nature of gene action, heritability in both broad and narrow senses in some summer squash for economic earliness traits. These traits included number of first female flowering node (No.1stF.F.N); date of first male flower (D.1stM.F.); data of first female flower (D.1stF.F.); first picking date (1stP.D.) and early yield per plant (E.Y./P.kg.). Seven imported squash varieties, namely Eskandarani (P1); Zucca Patisson custard white (P2); All Green Bush (P3); Courgette Orelia (P4); Sakiz (P5); Copi (P6) and Gapla (P7) were used as parental varieties in the present investigation. Diallel crosses (with reciprocals) were made between these parents to obtain 42 F1,1r hybrids according to the complete diallel crosses mating design. All genotypes were evaluated in randomized complete-blocks designs with three replications. The results indicated that the parental varieties Courgette Orelia (P4) and Gapla (P7) seemed to be the best combiners for earliness traits such as number of first female flowering node (No.1stF.F.N); date of first male flower (D.1stM.F.); data of first female flower (D.1stF.F.) and first picking date (1stP.D.). The parents Zucca Patisson custard white (P2) and Copi (P6) were the best combiners for early yield per plant (E.Y./P.kg.). In general, the performances of most F1,1r hybrids were variable and the results cleared that no hybrid was the best all for earliness traits. The results showed the importance of general (GCA) and specific (SCA) combining abilities. GCA was larger than their corresponding estimates of SCA for most earliness traits. Reciprocal effects (r) were significant for most earliness traits. In the same time, the estimates of heritability in broad sense were larger in magnitudes than their corresponding estimates of narrow sense.

Mechanical Properties and Dimensional Stability of Wood-Cement Particleboard from Tree Prunings Residues of Some Wood Species as Affected by The Panel Density
Mohamed
A. Abdel-Aal
The possibility of using tree prunings residues from four wood species grown in Saudi Arabia to create cement-bonded particleboards (CBPs) was studied. The properties of the produced CBPs at different board densities were evaluated. Panels were made using three different board densities (1100, 1200 and 1300 kg/m3) at a constant wood/cement ratio (1/2 by weight). The mechanical properties and dimensional stability characteristics of the CBP panels were determined. It was found that the tree prunings from the four wood species are suitable raw material to create CBPs after pretreating the particles in either cold or hot water and by using chemical additives. The results indicated that the panels produced from these tree prunings meet the mechanical and dimensional stability requirements of commercial CBP panels.CBP panels with good mechanical properties, good dimensional stability and a high level of board density (1300 kg/m3) should be used.

Two field experiments were carried out at the Research Experimental Farm of Sabahia, Agricultural Research Station, Alexandria during the two successive growing seasons of 2011/ 12 and 2012/ 13. G2006-77 sugarcane variety (Saccharum officinarum L.) was cultivated to investigate the effect of two planting dates, October (autumn planting) and in March (spring planting), three soil ploughing treatments (two, three and four passes). and two distances between hills (100 and 125 cm.) on sugarcane yield and its components. The results indicated that planting date did not affect the stalk diameter, stalk yieldand sugar yields but it significantly increased stalk length with spring planting. Four soil ploughings is fair enough for producing higher stalk length and sugar yield No-significant differences between values of stalk diameter and stalk yield affected by different soil ploughing numbers from 2, 3 and 4 in the 1st and 2nd seasons. No significant effect were found in stalk diameter, stalk yield and sugar yield during the two seasons by planting at (100 and 125 cm.) between hills.The interaction among planting date soil ploughing and distances between hills were significant with respect to stalk diameter, stalk yieldand sugar yields during both successive seasons. The planting dates had no significant effect during the 1 st and 2nd seasons on T.S.S. % and purity %. However there was significant effect during the two seasons on sucrose %. The highest values of sucrose % (15.60and 15.64%) were obtained as a result of spring planting in both seasons, respectively. Significant differences in T.S.S. %, sucrose % and purity % by number of ploughing were found in the two consecutive seasons. T.S.S. % the1 st season and sucrose % in the 1st and 2nd seasons were significantly different decreased with the distances between hills, No significant effect was found in purity % during the two seasons and T.S.S. % the 2nd season by planting at (100 and 125 cm.) between hills. Generally, as a conclusion and on the basis of the obtained results that planting G2006-77 sugarcane variety in spring planting season, 4 ploughings and 125 cm between hills produced the highest values of stalk length(cm.), stalk diameter (cm.), stalk yield (ton/ fed) and sugar yields(ton/ fed ) as well as T.S.S.%, sucrose% and purity % under Alexandria conditions

Two field experiments during the winter seasons 2012/2013 and 2013/2014 were conducted at the North Nile Delta region Sakha Agricultural Research Station Farm(31¯ 07° N Latitude, 30¯ 57° E longitude) to investigate the water behavior of sugar beet (Beta vulgaris L.) crop under different rates and doses of nitrogen fertilization on yield, some yield attributes, quality and some water relations. A split-split plot design with four replicates was used in the present study, where the main plots were randomly assigned by irrigation treatments which were irrigation at 55, 70 and 85% depletion of available soil moisture (I1,I2 and I3, respectively). While, sub-main plots were also randomly assigned by nitrogen rates which were N1, N2 and N3 (application of 30, 60 and 90 kg N/fed., respectively). Also, sub-sub main plots were randomly assigned by nitrogen doses which were as one, two equal and three equal doses through the growing season D1 , D2 and D3, respectively. The results indicated that the highest values of water applied, consumptive use and water storage were recorded under I1 in the two growing seasons and the values were (2751.0, 2790,4), (2235.5, 2250.2) and 2300.13, 2325.96 m3/ fed. On the contrary, the lowest values of the above-mentioned studied parameters were recorded under I3 and the values were 2259.6, 2293.2 and 1800.0, 1832.1 and 1990.18 and 2045.41 m3/ fed. For water applied, consumptive use and water storage in the first and second seasons, respectively. Concerning with water productively (WP) and productivity of irrigation water (PIW), the highest mean values were recorded under I1 and the mean values were 13.94, 14.01 kg / m3 for WP and11.34, 11.30 kg / m3 for PIW, but the lowest mean values were recorded under I3 and the values were 12.65, 12.55 kg / m3 and 10.08 and 10.03 kg / m3 for WP and PIW in the first and second seasons, respectively. Regarding water application efficiency, the highest mean values were recorded under I3 and the values are 88.08, 89.19% but the lowest mean values were recorded under I1 and the values are 83.61 and 83.36% in the first and second seasons, respectively. Concerning the effect of nitrogen rates and doses on consumptive use, WP and PIW, the highest mean values were recorded under N3 and D3. Data showed water storage and water application efficiency were slightly affected by both nitrogen rates and doses. Sugar beet root yield, top yield and root diameter were highly significant affected by irrigation treatments, nitrogen rates and doses in the two growing seasons. Where, the mean values for the abovementioned studied parameters were increased with increasing water applied, nitrogen rates and doses. Although root length increased with decreasing amount of irrigation water applied. Sugar yield, purity, nitrogen concentration in tops and roots increased with increasing irrigation water, nitrogen rates and doses. On the other hand, sucrose percentage increased with decreasing irrigation water and nitrogen rates but increased with nitrogen doses.

The wheat crop is one of important strategic which used by the producing countries as a mean of political and economic pressure on developing countries. Where self-sufficiency rate is estimated at about 56% during the year 2012/2013, and the problem in this research is concerned about unjustified increase in the cost of producing wheat crop as a result of rising input prices, while production did not increase the selling price of the crop at the rate commensurate with the high prices of production inputs. The research aims to identify some of mechanisms that causes increase in production volume in Dakahlia Governorate, and reduce the size of the food gap of this crop by studying the functions of production and cost functions to identify the reasons for the high production costs. The study revealed that functions of production of wheat crop study sample for each category possessory from three categories of possessory, that farmers Category possessory first (less than feddan) sample study produce in stage non-economic terms that flexibility productivity for the class of possessory first was 1.18 which is the first phase of the law of diminishing returns that explained production flexibility and presence of extravagance in the use of production elements and therefore must work on the use of the optimal combination of the elements of production until they get higher production and greater net profit. While farmers possessory of second category (from one to three feddan) and farmers possessory of third category (greater than three feddan) producing in the economic phase that flexibility productivity was about 0.86, which consider second phase of the law of diminishing returns. When estimating the cost functions of the three classes of possessory its obvious that farmers for possessory second category (from one to three feddan) are more farmers in order to achieve economic efficiency in terms of the optimal use of agriculture economic resources. In light of this the research conducted that:
1- Need to work on reducing the prices of production inputs, especially for the wheat crop as a strategic crop important.
2- Activate the role of agricultural extension in order to work to provide guidelines for agricultural farms, which in turn leads to optimal use of agricultural resources and thus reduce production costs.
3- Raise the selling price of the crop to suit the high prices of production inputs.

The experiment has been carried out in El-Ariyal Agricultural project, Wadi Al- Shati (in the south of Libya), the experiment was done in four months period starting from January to April, 2010. The samples were twenty male lambs of Barbary sheep were randomly selected from the same flock at weaning age (3-4 months age and 7.5 ± 10.5 kg live weight). Lambs were weaned at the same time and randomly divided into two groups (10 lambs each group). The groups were housed in two separate shelteres and numbered by plastic and metal numbers. Animals were given an adaptation period for 15 days before starting the experiment.
Lambs were fed dry Alfalfa and Oat hay (as roughage feeds) in addition to that they were fed 500 g of concentrated mixture twice a day. the amount of concentrated mixture was divided into two portions (250 g in the morning - 250 g in the evening). The water was given twice a day before the sample was fed the concentrated mixture. Each lamb was weighed before and after the process of feeding started. The process of weighing was done every fifteen days systematically until the end of the experiment. Results of the experiment are illustrated as follows: the results showed significant decrease of weight in the castrated lambs compared to control lambs. Moreover, there was no significant difference showed in blood concentration of glucose. The total lipids did not show any significant change between the two groups. However the cholesterol concentration was significantly higher in serum of the castrated lambs compared with intact lambs, starting from day 105 until the end of the trial. The results of this experiment showed the castrated Barbary lambs performance were lower compared to international sheep breeds.
