This study aimed to investigate the stimulation of the formation of phenolic compounds in callus cultures of Origanum vulgare using nanomaterials. Different combinations of plant growth regulators (NAA, BAP, and TDZ) were applied to form the calli from leaf explants. The optimal effect was achieved with a combination of 1 mg/L NAA and 0.5 mg/L BAP, which resulted in an initiation rate of 100% along with significant increase in both fresh and dry weight. The addition of silver nanoparticles (Ag-NPs) and titanium dioxide nanoparticles (TiO₂-NPs) at different concentrations (1, 2, and 3 mg/L) to the culture medium led to a substantial decrease in the fresh and dry weight of calluses with a significant increase in the

This study was aimed to evaluate detection of T. gondii in blood DNA based on the B1 gene and serologically, also to investigate the effect of some risk factors (sex, ages, breeds and flocks). A total of 190 goats were included. The blood samples were obtained from the jugular vein and subjected to nested PCR (nPCR) and Elisa for detection of T. gondii. The results obtained that the prevalence was 24.21% by nPCR and 46.31% by ELISA with significant differences. The degree of agreement between nPCR and ELISA was a slight (Kappa=<

This study was conducted to estimate (Co) variance components of a sexual and egg production traits in Iraqi brown local chickens. Data on 2234 pedigreed hens for successive six generations of selection for high egg production during the first 24 weeks of laying were used. Data of first egg weight (FEWT), body weight at sexual maturity (BWSM), age at sexual maturity (ASM), egg number (EN), egg weight (EW) and egg mass (EM) were recorded individually. The univariate and bivariate animal models under Average Information Restricted Maximum Likelihood (AI-REML) were applied to estimate the variance component and the BLUP breeding values. The average of the traits mentioned above was 35.7g, 1489.59g, 149.31d, 109.32 egg/hen, 44.80g an

This study aimed to examine how including dietary dried rosemary leaves (DRL) of Holstein bulls affects methane production and certain rumen fluid characteristics in vitro. Rumen fluid was obtained from newly slaughtered calves and used in two separate trials: one for gas production and another for digestion. In the trials, two diets were implemented. The first was the standard diet for bulls, consisting of a concentrate diet and alfalfa hay (control group). The second diet included the addition of 250 g DRL to the essential diet. There was a significant decrease (P≤0.01) in methane and N-NH3 production, as well as in the ratio between unsaturated fatty acids (USF) and saturated fatty acids in the rosemary group compar

This study aimed to assess desertification and land degradation in an arid and semi-arid climate (Al-Nasr area, Dhi Qar Governorate). We used the MEDALUS and modified MEDALUS models with three scenarios, in conjunction with GIS mapping techniques, to identify desertification risks in one Iraqi governorate. After creating a desertification database containing 19 criteria, the first steps consisted of mapping four MEDALUS indicators, including soil, vegetation, climate, and land management. The next step involved adding other indicators such as irrigation water. All layers weighted by environmental conditions present in the region were then used according to the same MEDALUS framework to create a desertification map. The results sh

This study was carried out to identify the effect of the quantitative trait loci (QTL) region on some productive and physiological traits of Iraqi chickens. One hundred five and ten-week-old laying hens were used and bred in individual sages from sexual maturity to 100 days of production. Blood samples were collected from the brachial vein for DNA extraction and serum isolation, and then polymerase chain reaction (PCR) was done to determine the target region of the QTL. Two groups were obtained: the first had a PCR product with band 294 bp denoted (P) and the second had no PCR product denoted (NP). The P group had a significant (p < 0.05) effect on egg weight at the second stage of the study amounted 48.23 gm. and a significan

This study aimed to investigate the impact of increased water flow and two different air speeds on water consumption and cooling performance in modify air coolers. An experiment was conducted using an air cooler with an additional water pump to facilitate increased water flow. One Way ANOVA with regression and Tukey was used. Findings revealed that practical water consumption significantly surpassed theoretical estimates, primarily due to heightened resistance encountered by water as it traversed the cooling pads. Notably, the implementation of two water pumps improved cooling, effectively lowering room temperature by7-10 °C (Δt of 9.4°C); however, this enhanc

This study aimed to investigate the specific adsorption of heroin made from morphine that extracted opium. Using acrylamide and n-iso propyiacrylamide as the functional monomers, n,n′-methylenebisacrylamide as the crosslinker, and benzoyl peroxide as the initiator. At bulk heroin concentrations of 20, 40, 60, 80, and 100 ppm in ethanol solution, this MIP's maximum heroin adsorption capacity of 3.87 mg/g at used 0.2 gm acrylamide as monomer which was among the best capacities documented in the literature to date. The adsorption capacity, selectivity separation, reusability, and chemical stabilities of the molecularly imprinted polymers were confirmed by thermodynamic analysis, experimental characterization, adsorption investigat

This study aimed to investigate the impact of fish oil levels on the growth performance, feed efficiency, and body composition of common carp. The study divided 56 common carp into four treatment groups and fed diets containing different levels of fish oil over 56 days. Results showed significant differences in growth performance and feed efficiency between the treatments. The T3 (1.5% fish oil) and T4 (2% fish oil) groups showed the highest weight gain and most efficient feed conversion ratio, suggesting that 1.5% fish oil may support growth outcomes like those with 2% fish oil. Body composition analyses revealed favorable protein-to-fat ratios, suggesting improved nutrient retention and lean growth with reduced fish oil levels.
