Relevance. The article provides a justification for the use of sheep selection taking into account the intra-breed type of Prekos ewes in purebred breeding and crossing with producers of semi-fine wool breeds Romney-Marsh and Kuibyshevskaya to improve the biological usefulness of meat in offspring.Methods: scientific and economic experiment in the use of different selection options, taking into account the productive type of sheep of the Precos breed.Results. The article presents the results of a study on the influence of the selection of sheep on the composition of lambmeat, increasing the usefulness and quality of meat and, thus, the efficiency of its production. It was found that the content of water in the meat of crossbred animalswas lower compared to purebred Precos. There is a lower water content in the meat of rams obtained from sheep of the Precos meat-wool type, both in purebred and crossbred animals. In terms of the protein content in meat, there is an advantage in rams with purebred breeding and crossing compared to meat obtained from the wool-meat type of queens. In the hip bran of purebred animals and crossbreeds with the Kuibyshev breed, this superiority was 1.1% (Р > 0.95), and in the lumbar bran of Romney-Marsh crossbreeds, this difference was 1.6% (Р > 0.95). Mutton from the offspring of the sheep of meat-wool type is characterized by a significantly high content of the essential amino acids threanine, lysine, leucine, phenylanin and isoleucine in comparison with meat from the offspring of the wool-meat type of sheep. A significant superiority was also established in the content of interchangeable amino acids — oxyproline, serine, tyrosine, proline, glycine, aspartic and glutamic acid, cystine and analin.

Background: Urinary tract infections in pregnancy can be complications if the microbes causing it are proven to be resistant to standard use antibiotics. Routinely a multi-dose regimen of nitrofurantoin is used as a management protocol, however recent literatures have highlighted the relative efficacy of Fosfomycin in successful treatment. The present study was done to comparatively assess the efficacy of single dose Fosfomycin and standard dose nitrofurantoin in UTI among pregnant females, Methodology: Study employed a pool of 60 subjects divided equally in two groups. The groups were provided either with Fosfomycin or nitrofurantoin. Observations: Fosfomycin showed a lower rate of side effects and microbial resistance as compared to nitrofurantoin. The clinical and laboratory analysis revealed a statistically significant superiority of Fosfomycin in the selected study sample. Conclusion: Fosfomycin showed a better outcome compared to nitrofurantoin in the selected study sample. Keywords: Fosfomycin, Nitrofurantoin, Pregnancy, UTI

This study focused on elucidating the possibilities of improving current trapping methods for Ips typographus (Linnaeus, 1758). Three field experiments were conducted simultaneously in one study area in the German federal state of Saxony. A comparison of six different commercial attractants revealed a significant superiority of Typosan®, especially for adult beetles after hibernation in the phase of their first swarming. It also attracted fewer individuals of Thanasimus spp. than the other highly attractive products Pheroprax® and IT Ecolure Extra®. Increasing the Pheroprax® application rate by using four instead of one dispenser in a single trap increased the total catch of I. typographus only by 15.5%. In contrast, Thanasimus spp. catch increased by 195.5% when four dispensers were used. A test of different trap types showed a species-specific catching capability, with the 12-funnel WitaTrap® being the most effective in catching I. typographus. The quantity of Thanasimus spp. bycatch in multiple-funnel traps demonstrated the necessity of a selective mechanism to minimize impacts on predator populations. Although we were not able to identify new milestones towards mass trapping, this study contributes to necessary improvements of current trapping methods. Especially in future stands with a smaller share of Norway spruce (Picea abies Karsten, 1881) the weakened beetle population in spring could be effectively reduced by properly conducted mass trapping.

Abstract. The world has always been striving to increase and intensify agricultural production, and there are several attempts to acheive that, such as grafting tomato on potato to obtain two crops from one plant. This investigation was conducted during 2020 in open field in Nahl village, Baniyas, Tartous Governorate, Syria. The vegetative and generative growth and yield have been studied for pomato (grafted tomato on potato) and compared to each tomato and potato separately. Tomato plants were significantly superior in plant height to pomato plants after 23 days of planting until the end of the experiment. On the other hand, there were significant differences between tomato plants and pomato plants in the leaf area after 23, 51 and 65 days of planting. Also, tomato plants significantly outperformed pomato plants in the number of flowers and fruits per plant and the tomato fruit set percent. Anyway, tomato plants were significantly superior in the average yield of tomato fruits per plant (1657 g.plant-1) to pomato plants (185 g.plant-1), while there were insignificant differences in the average yield of potato tubers per plant between pomato which failed to produce tubers and potato (48.25 g.plant-1). Studying the tomato fruit fresh weight showed a significant superiority of tomato plants (54.37 g.fruit-1) to pomato plants (35.97 g.fruit-1), while there were insignificant differences in the other physical (tomato fruit height, diameter and shape index) and chemical (tomato fruit content of total acids, total soluble solids and dry matter, %) properties.

Most current studies on multi-agent evolution based on deep learning take a cooperative equilibrium strategy, while interactive self-learning is not always considered. An interactive self-learning game and evolution method based on non-cooperative equilibrium (ISGE-NCE) is proposed to take the benefits of both game theory and interactive learning for multi-agent confrontation evolution. A generative adversarial network (GAN) is designed combining with multi-agent interactive self-learning, and the non-cooperative equilibrium strategy is well adopted within the framework of interactive self-learning, aiming for high evolution efficiency and interest. For assessment, three typical multi-agent confrontation experiments are designed and conducted. The results show that, first, in terms of training speed, the ISGE-NCE produces a training convergence rate of at least 46.3% higher than that of the method without considering interactive self-learning. Second, the evolution rate of the interference and detection agents reaches 60% and 80%, respectively, after training by using our method. In the three different experiment scenarios, compared with the DDPG, our ISGE-NCE method improves the multi-agent evolution effectiveness by 43.4%, 50%, and 20%, respectively, with low training costs. The performances demonstrate the significant superiority of our ISGE-NCE method in swarm intelligence.

Abstract The experiment of one factor was carried out in the greenhouse of the University of Kirkuk - College of Agriculture - Agricultural Research and Experiment Station for the two agricultural seasons 2020-2021, by planting the seeds of the Carnations (Nanus) plant in special dishes for planting seeds filled with peat moss on 1-10-2020, when the reaching the required size of the root system, the seedlings were transferred on 20-1-2021 to the final and required size of the pots with a diameter of (13 cm) and were treated with two types of plant growth retardants (Alar and Paclobutrazol) at two different levels in addition to the control treatment (100-200) mg.l−1 Alar, (100-200) mg.l−1 Paclobutrazol and the spraying process was repeated 15 days after the first spray. The experiment resulted in a significant superiority of Paclobutrazol at the concentration 200 mg.l−1, as it was significantly superior by giving the lowest plant height and the highest flowers diameter compared to Alar factor and the control treatment, while Alar was significantly superior at the concentration of 100 mg.l−1 by giving the largest number of plant branches and the largest number of flowers compared to Paclobutrazol and control.

The treatments were distributed as follows: T1: added the premix to diet supplied by Nuscience Company. T2: added the premix to diet supplied by Provimi Company. T3: added the premix to diet supplied by Max Care Company. T4: added the premix to diet supplied by INTRACO Company. The results show that there were no significant differences in the relative weight of the shell, except for the mean, a significant superiority of T2 and T4 compared T3, a significant differences in the shell thickness. There were no significant differences in the relative weight of albumin, and a significant superiority in the general average, where T2 outperformed on T4. There were no significant differences in the yolk index. T3 and T2 were significantly superior to T1.

Abstract The current study was conducted in the postgraduate laboratory of the college of Agriculture/University of Al-Muthanna/Department of Animal Production, which aimed to find out the effect of follicle diameter and the culture medium on the percentage of in vitro maturation of sheep oocytes (Ovis Aries). The experiment included in vitro maturation of sheep oocytes aspirated from large, medium and small follicles in different culture media (named A, B and C). In vitro maturation of oocytes was carried out using three culture media that differed only in the concentration of sucrose, which were 0. M, 0.25 M and 0.5 M for A, B and C culture media respectively. The results of the current study showed significant superiority (P ≤ 0.05) of culture medium C than the two media A and B in the percentages of in vitro maturation, which were to 38.0 ± 1.71 %, 27.37±1.47 % and 21.902±0.76 % for C, A and B respectively. The results also indicated significant effect (P ≤ 0.05) of follicle diameter in the percentages of in vitro maturation of sheep oocytes which were 38.0±1.71 %, 29.57±2.06 % and 18.5± 0.27 % for large, medium and small follicles respectively. It could be conclusion from the present study that the follicle diameter and culture medium had a significant effect on the percentage of in vitro maturation of sheep oocytes.

Abstract A field experiment was carried out during winter agricultural season 2020/2021 in Babylon Governorate in at Tajieh region, southeast of Hilla city, to study the effect of planting dates and nitrogen fertilizer on the growth and yield of safflower. The experiment included two factors: planting dates (1 and 15 November and 1 December), and nitrogen fertilizer at levels (0, 90, 120 and 150 kgN.ha-1), the treatments were distributed in a factorial experiment with a randomized completely block design (RCBD) with three replicates. The results showed significant superiority of planting date at December 1 on most growth and yield components parameters, it recorded the highest averages on seed yield, dry matter yield and harvest index amounted to 1576.2, 6126.0 kg.ha-1 and 25.6% respectively. However, nitrogen fertilizer at concentration 150 kg N.ha-1 affected all growth and yield and its components, it gave the highest averages for seed yield, dry matter yield and harvest index amounted to 1762.2, 6626.8 kg.ha-1 and 26.6%, respectively.

Abstract Twenty-eight isolates of Lactobacillus bacteria were isolated from the rhizosphere of pea plants grown in the fields of five districts in Salah al-Din, which included: Tikrit, Al-Alam, Al-Sharqat, Samarra and Baiji, diagnosed according to phenotypic and biochemical tests. Results showed the effect of L. paralimentarius 1081 on vegetative growth characteristics. Treatment of (bacterial filtrate + Ridomil in the presence of pathogenic fungi) was recording the highest values in dry weight of the vegetative and root systems, was 3.91 and 1.23 g respectively in the local cultivar, compared with the lowest values was 2.60 g and 0.76 g respectively in the Syrian cultivar. All treatments inducing plant resistance compared with healthy plants, and the highest activity of the Peroxidase and Polyphenol oxides in the treatment of (Bacterial filtrate + ridomil in the presence of pathogenic fungi), were 1.08 and 1.33 units/ml in the local cultivar, compared to the Syrian cultivar were 0.015 and 0.013, respectively. Results showed a significant decrease in the severity of infection for all treatments compared to the pathogenic fungus treatment, and the lowest infection severity of the vegetative and root systems was recorded in the treatment of (Bacterial filtrate + ridomil in the presence of pathogenic fungi), which was 14.11 and 12.47% in the local cultivar. There was a significant superiority of all treatments in productivity parameters of pea compared to the treatment of pathogenic fungi only, the highest of those parameters including weight of pods and grains weight/plant were recorded in the treatment (Bacterial filtrate + ridomil in the presence of pathogenic fungi) for the local cultivar was 18.07 g and 14.04 g compared to 10.43 g and 8.20 g in the treatment of the Syrian cultivar with pathogenic fungi only.
