Methylation Sensitive Amplification Polymorphism (MSAP) was used to characterize the alterations in DNA methylation in maize (Zea mays L.) inbred lines and their half-daillels affected by plant densities (213333 plant h-1 and 13333 plant h-1). The two restriction was enzymes ( HpaII and MspI) succeeded in diagnosing a total of 23 specific loci, most of (22 loci) were Methylation Sensitive Loci (MSL), while the only one NML (No Methylated Loci) was monomorphic. Thirteen out of 22 MSL loci polymorphic, recording a were polymorphism percentage of 59%. Results of FeSOD gene expression cleared the different response of maize inbreds and hybrids to high plant density stress. Generally, the expression of  the targeted gene

This study was conducted to produce xylose by acid hydrolysis from lignocellulose by product . The process of acid hydrolysis carried out using dilute H₂SO₄ to hydrolyze the available sources of  lignocellulosics  in Province of Wassit being (corn stover, rice husk, reed and wheat straw) ,wheat straw was selected as the best source for hemicellulose  (35)% as compared to the above mentioned sources. The hydrolysis  process included  two separated experiments ,acid hydrolysis of autoclaved and non- autoclaved wheat straw using the following reaction conditions  [(0.5, 1 and 1.5%) sulfuric acid solution, (1, 2 and 3hrs) hydrolysis time and (1:10, 1:15 and 1:20) solid to liquid rat

Ground wheat straw autoclaved and non-autoclaved (l0g) was treated with 6, 8 and 10%  sodium hydroxide of 1:10, 1:15 and1:20 mixing ratio for 1, 2 and 3hrs as reaction time. Results revealed a maximum value (18.79 %) of xylose were found in hydrolysate when autoclaved wheat straw was treated with 8% NaOH for 2hrs , whereas  the lowest value was (13.52) % when the non autoclaved wheat straw (  6% sodium hydroxide concentration , 1h reaction time  and 1:10 solid: liquid ) used. Also, results indicated that  the highest level of furfural (0.34) % was observed when 10 % sodium hydroxide  solution  over 3 hrs incubat

To investigate the influence of zeranol administration by implantation and castration on fatty acids composition, 20 weaned kids (3-4 month old) with an average live weight of 17.3±0.23 kg were divided randomly into two equal main groups, the first was left intact as a control and the 2^nd group was castrated. Each main group was then blocked randomly into two sub groups, the 1^st was left as control and the 2^nd implanted with Ralgro (12mg zeranol). Kids were fed a concentrate adlib and slaughtered after 70 days of fattening. After chilling for 24 hours, a homogenous samples of meat from L.dorsi  muscle was blended for analysis of fatty acid composition. Results revealed that mono uns

This research aims to identify the productive relationship nature among the elements used in the agricultural companies by estimating the translog cost function. It also aims to recognize the possibility of substituting these elements with each other, to identify the nature of revenues, and economies scale through elasticity of other cost. This research goes further to define the typical use of resources, identify the performance of the companies and their contribution in controlling their cost, and estimating elasticity of substitution (Allen-Uzawa), (Morishima).  The translog cost function was estimated so as the total cost of the agricultural companies is a function of the prices of production and production quantity outp

This study was carried out using 94 ewes at Erbil plain - Kurdistan region-Iraq, during the period from May 2016 to April 2017. The overall mean mortality rates from birth to 7 days and from 8 days to weaning age were 8.6 and 6.6%, respectively. Age of dam, type of birth, weight of the dam at matting, Body Condition Score (BCS) and birth weight had an important significant (P<0.05) impact on lamb mortality from birth to 7 days and from 8 days to weaning age. This research revealed  that a higher  lamb  mortality (4.2%) was registered for  dams aged  2 years, while a  lower mortality(6.6%) was found in dams aged 5-6 years, no significant differences in mortality among males and females were appeare

The slides were examined macroscopically. The results showed that coagulative degeneration, degeneration of hepatocy

This study was conducted to assess soil salinity forecasting using spectral soil reflectivity. Artificial salinization was carried out on silty clay loam soil. Collected soil sample was handy crushed, sieved through a 4 mm sieve and backed in plastic columns. The columns were closed from the bottom with a perforated plastic lids with the presence of sand-gravel filter. Columns placed vertically at plastic basins contain saline ground water and left for salinization by capillary rise. At the desired salinity level, soil reflectivity was measured using spectroradiometer and wave length between 350-2500 nm, and band width 1 nm. Soil salinity and moisture were determ

The objective of this study was to evaluate the antibacterial effect of Phyllanthus emblica extract by (ethanol: methanol 1:1) against Pseudomonas aeruginosa, Staphylococcus aureus and Escherichia coli at different concentration started with 20, 10, 5, 2.5, 1.25 and 0.625 mg/ml. The antibacterial activity was determined by the agar well diffusion method to investigate the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC). The alcoholic extract of Phyllanthus emblica had the highest antibacterial activity at 20 mg/mL and 5 mg/mL except in Pseudomonas aeruginosa where the value of inhibition was between 20 mg/mL and 10 mg/mL whereas The MIC concentration

Iraq has been endemic for Newcastle disease virus (NDV) with natural infection causing significant losses in the poultry industry since 1968. This study was designed to  identify a natural infection of NDV  occurred in three governorate in the northern part of Iraq (Erbil, Sulymaniyah and Duhok)  among chicken flocks and estimate its virulence  by the mean death times(MDT) and intra-cerebral pathogenicity index (ICPI). Ninety six flocks with high mortality were examined for post mortem lesions and the samples collected from suspected ND chicken flocks, either sick or dead showed characteristic clinical findings and show positive rapid test for NDV antigen. The collected sample

The aim of this study was to investigate the effect of deprivation on productive traits of newly post hatched chicks. A total number of Ross 308 birds (120) were divided into four groups as in the following way: group1 (G1=38 bird), was regarded as positive control and had been supplied directly with the feed, whereas group2 (G2=27 bird), group3 (G3=28 bird) and group4 (G4=27 bird) were supplied with the diet at post hatch period of 24h, 48hr and 72h respectively. Water supplied was ad libitum to all groups immediately after placing. Result revealed that G1 showed significant performance (P<0.05) according to the level of yolk sac absorption (Y.S.A), Feed Conversion Ratio (F.C.R). The final body weight gain (B.W.G) sh

A stochastic frontier approach is used for analyzing of the environmental impacts of soil salinity in Iraq. An econometric method based on the neoclassical production theory (stochastic frontier analysis) is transformed to enable the definition and estimation of environmental efficiency of wheat production farms in irrigated areas in central Iraq. The study is based on a sample of 360 farms. Farms were divided into three sub groups according to the soil salinity level - low salinity, medium salinity, and high salinity. The empirical results indicate that farmers are broadly environmentally inefficient. Based on an improved input mix, the average potential environmental impact reduction for low, medium, and high salinity farms is
