One of the main factors that ensure the growth of profitability of poultry farming is the partial replacement of grain crops with non-traditional feed with low cost, which, for example, can be considered processed dry bird droppings (SPP). The aim of the research was to study the effect of organic concentrate based on SPP on the morphological parameters of quail eggs. For the study, 5 experimental groups of quails were selected using the method of analog pairs. The birds of the control group received factory-made feed DC-52-100 %, the quails of the experimental groups (I, II, III and IV) were replaced by 10, 15, 20 and 25% by weight, respectively, with an organic protein concentrate based on SPP. In studies, it was found that the introduction of an organic concentrate based on SPP in the amount of 10, 15, 20, 25 % instead of a similar amount of mixed feed contributed to an increase in the relative weight of the yolk by 1,55; 4,51 (P≤ 0.05); 0,64 and 1,87 %, a decrease in the protein/yolk ratio by 2,07; 6,74 (P≤ 0.05); 0,52 and 3,13%, respectively, relative to similar indicators of eggs of the control group. The addition of organic concentrate based on SPP to the composition of mixed feeds contributed to the improvement of the morphological parameters of food eggs and the quality of the shell. The weight of eggs practically did not change when replacing 10,0% of the complete feed with a similar amount of organic concentrate, while the picture was ambiguous when increasing the dose of the test feed.

The article presents the results of the effect of partial replacement of mixed feeds with organic concentrate based on dry bird droppings (DBD) on the preservation of quail, quantitative and qualitative rates of egg productivity. For the laboratory experiment, 5 experimental groups of Manchurian quail were formed by the analogous pair comparison method. The quail of the control group consumed all-in-one feed (AF), for the quail of the experimental groups (I, II, III, and IV) part of the AF – 10, 15, 20 and 25 % by weight – was replaced with organic concentrate. Results of studies reveal that the introduction of 10 % of organic concentrate into the AF contributed to improved feed intake and livestock safety, increased egg productivity and reduced feed consumption per unit of output. With respect to the indicators of biological usefulness, toxicological and sanitary-epidemiological safety, quail eggs treated with the organic concentrate met the requirements of GOST and TR TS 021/2011 “On food safety”.

In modern poultry farming the most urgent tasks are to search for and test new environmentally safe feed and economically justifi ed additives that stimulate productivity, positively aff ect the health of poultry, and consequently increase the livability of livestock and other important zootechnical traits. In order to maintain physiologically normal processes of life, metabolism and increase the level of productivity of poultry it needs mineral components and their chelated compounds. The purpose of this work was to increase the egg productivity of poultry by using the silicon-containing poly additive Nabicat in feeding young hens and laying hens. The researches have been carried out on the poultry cross Highsex Brown under the environments in CJSC “Poultry Farm “Volzhskaya” in the Sredneakhtubinsky area in the Volgograd region. In this paper, The optimal dose of the introduction of the silicon-containing poly additive Nabicat in the diets of young and laying hens of the cross Highsex Brown has been scientifi cally justifi ed and the biological value of using an organic form of silicon has been determined. The positive infl uence of the optimal dose of poly additive on growth, consumption, and digestibility, nutrient metabolism in the poultry body, as well as egg productivity and quality of the resulting egg has been revealed. Thus, the average egg productivity per 1 hen in the control group during the experiment period was 321,3 pcs., and in the 1st, 2nd and 3rd experimental groups it was 322,6 pcs., 325,8 and 325,7 pcs., which was higher than in the control group by 0,40 %, 1,40 and 1,37 %, respectively. The average egg weight in the 1st experimental group exceeded the control by 0,43 g or 0,68 %, in the 2nd experimental group by 1,16 g or 1,84 %, in the 3rd experimental group by 0,81 g or 1,28 %. The economic eff ectiveness of using the organic silicon additive in the composition of Nabicat poly additive in the feeding of laying hens has been proved. The economic eff ect due to the use of diff erent doses of the introduction of silicon-containing poly additive Nabicat in compound feed for laying hens of the 1st experimental group was 141,66 rubles, the 2nd experimental group 962,76 rubles, and the 3rd experimental group 821,89 rubles.

AbstractThe characteristics of computer-assisted instruction (CAI) which makes it so worthy of consideration for use by the teacher of pupils with special needs, whose time for individual attention with her pupils is limited, are briefly discussed, and comment is made about the limitations of this approach. Attention is drawn to the alternative approach of peer tutoring, where the desirable one-to-one characteristic is attainable, and where there is the possibility that the sensitivity to the quality of the computer program, which is one of the limitations of the approach of CAI, may be contrasted with the not-so-sensitive-to-quality-of-program characteristic of peer tutoring. This possibility is examined in the context of a sample of poor reading Year eight pupils who were given a period of peer tutoring by Year eleven and twelve pupils in the same school, where the demonstrably not high quality program consisted of relatively few meetings between tutor and tutee, of short duration, at which it was expected that there would be talk, reading and being read to. Use of a control group enabled the conclusions to be reached that this peer tutoring resulted in gains for the tutees in reading ability and in attitude towards and behaviour in school, this being suggestive of the power of this low staff input, low cost, low technology technique in the area of special education.

Compound feed are subject to requirements for their composition, since they use several types of grains that contain anti-nutritive substances that reduce the digestibility and use of nutrients. One of the tasks of domestic poultry farming is to reduce losses by increasing the digestibility and accessibility of feed. Among the most effective ways to solve this problem is to add enzymes to the feed of poultry. The inclusion of enzyme drugs in the composition of compound feed contributes to the inactivation of anti-nutritive substances, which contributes to an increase in the coeffi cient of digestibility of nutrients. The purpose of the work was to establish the feasibility and eff ectiveness of the enrichment of compound feed used in the production technology of chicken eggs with mixtures of enzyme drugs of domestic production of Amylosubtilin G3x, Cellolux-F and Protosubtilin G3x. Three groups of laying hens with 57 heads in each have been formed: a control group and two experimental groups. The duration of the experiment was 420 days. Laying hens of the control group have been received farm compound feed depending on their age. Laying hens of the 1st experimental group have been received compound feed of the control group enriched with the enzymes Amylosubtilin G3x and Cellolux-F depending on the age. In the compound feed of laying hens of the 2nd experimental group enzyme drugs were additionally introduced depending on the age Amilosubtilin G3x and Protosubtilin G3x. Higher egg production rates have been observed in the 1st experimental group – 357,81 eggs, which was 6,48 % higher than in the control group and 1,84 % higher than in the 2nd experimental group. The weight of eggs of laying hens of the 1st experimental group was 1,85 g or 2,97 % more, and the 2nd experimental group was 0,7 g or 1,12 % more than in the control group. The diff erence between the egg weight in laying hens of the 1st and 2nd experimental groups was 1,85 % or 1,15 g. The lowest feed consumption of 1,37 kg for the production of 10 eggs was in the laying hens of the 1st experimental group, which was less than the indicator of the control group by 10,94 and by 4,2 % than in the 2nd experimental group.

Based on the results of the analysis of feed materials on the content of micronutrient elements and conducting scientific experiments on broilers chicken, the most effective source of Manganese, Zinc, Iron and Copper in mixed feeds, which contributes to solving the problem of increasing the quality of feeding and intensifying the growth of poultry has been substantiated. The optimum source of essential elements (Mn, Zn, Fe, Cu) for broilers chicken through feeds, the level of their incorporation into mixed fodders have been experimentally determined, and their influence on productivity and feed costs per 1 kg of body weight gain have been investigated. The tasks set in the work have been solved experimentally using analytical (analysis of literature sources), zoo-technical (growth indices, feed intake) and statistical (processing of the results obtained) methods of research. The use of mixed feeds in feeding broilers chicken which contained glycinate of Manganese, Zinc, Iron and Copper making 75 % of the needs, contributes to increasing their body weight by 2.5 % and increasing the growth rate by 2.4 %. Feed costs per 1 kg of broilers chicken growth were 1.5 % lower than the young bird index of the control group.

ObjectiveTo establish the benefits of an early, tailored and low-cost exercise intervention in older patients hospitalised for acute coronary syndrome (ACS).MethodsThe study was a multicentre, randomised assessment of an exercise intervention in patients with ACS ≥70 years with reduced physical performance (as defined by the short physical performance battery (SPPB), value 4–9). The exercise intervention included four supervised sessions (1, 2, 3, 4 months after discharge) and home-based exercises. The control group attended a health education programme only. The outcomes were the 6-month and 1-year effects on physical performance, daily activities, anxiety/depression and quality of life. Finally, 1-year occurrence of adverse events was recorded.ResultsOverall, 235 patients with ACS (median age 76 (73–81) years) were randomised 1 month after ACS. Exercise and control groups were well balanced. Exercise intervention improved 6-month and 1-year grip strength and gait speed. Exercise intervention was associated with a better quality of life (as measured by EuroQol-visual analogue scale at 6 months 80 (70–90) vs 70 (50–80) points, p<0.001 and at 1 year 75 (70–87) vs 65 (50–80) points, p<0.001) and with a reduced perception of anxiety and/or depression (6 months: 21% vs 42%, p=0.001; 1 year 32% vs 47%, p=0.03). The occurrence of cardiac death and hospitalisation for cardiac cause was lower in the intervention group (7.5% vs 17%, p=0.04).ConclusionsThe proposed early, tailored, low-cost exercise intervention improves mobility, daily activities, quality of life and outcomes in older patients with ACS. Larger studies are needed to confirm the clinical benefit.Trial registration numberNCT03021044.

Background: Bursa of Fabricius (BF) and the thymus are primary lymphoid organs of poultry and play a major role in avian immunity. Enteric system is also involved in immunity. Several pathologic conditions directly impact BF and thymus size, and also affect intestinal parameters. Besides, there are several immune system depressor agents which affect birds. The selection of glucocorticoid as inducer of immunosuppression is applied in many experiments; however there are few studies that are applied to the reality in the field. In this context, the aim of this study was to evaluate the effects of dexamethasone as an inducer of immunosuppression on lymphoid organs and microscopic structures of the jejunum.Materials, Methods & Results: One-day-old chicks were used as a control group (n = 8) and the treated group (n = 25) received intramuscular dexamethasone on 21, 23, 24 and 26 day-old. Control birds and treated birds were euthanized 8, 16, 24, 32 and 40 h after inoculation; four control birds and six treated birds were euthanized on the eighth day after the last inoculation. Thymus, BF and jejunum were collected during the necropsy. The selected organs were processed, stained with hematoxylin and eosin and photographed. The BF and thymus cuts were evaluated by three histopathologists to determine the depletion score. Ten villi of each jejunum were evaluated for width and length of villi, depth crypt, microvillus length, enterocyte length of each villus, and wall thickness. Treated birds presented a mean weight lower than control group during all the experiment. The mean weight and the relative weight of the BF and thymus of control birds were significantly higher than treated ones. The lymphocyte depletion in BF and thymus scores differed significantly between groups, being higher in the group challenged with dexamethasone. There were no significant differences between groups for depth of crypt, height of core and height of microvilli. The intestines of the control group had higher mean values for length of villi, width of villi, height of enterocyte and thickness of wall. Significant correlation between weight of thymus and weight of BF, between weight of thymus and weight of bird and between weight of BF and bird weight were found.Discussion: Easy administration, low cost and the absence of suffering during inoculation make the use of glucocorticoids more advantageous to mimic immunosupression in poultry. Treatment with dexamethasone interfered directly in the weight of the birds. Evaluation of immune response of birds can be performed by the ratio of the BF weight in relation to the weight of the bird, as observed in the present study. The relative weight of the BF of untreated animals varied at all ages between 0.21% and 0.29%. It was also observed that the relative weight of BF and thymus in immunosuppressed birds tended to increase according to the end of the treatment. Depletion scores were higher in thymus, suggesting that glucocorticoid promoted more harmful effects on this organ. Dexamethasone had negative influence on length of villus, once mean value was 13% lower than those of control group. Width of villus and height of enterocyte core of treatment group were lower than those observed in control animals. Coefficient of determination greater than 70% was observed for almost all established relationships, except for the length of villi and weight of the thymus. Administration of dexamethasone promotes significant and negative effects on the gain of weight, length of villi, width of villi and height of enterocytes. These finding are useful for future experiments with controlled immunosuppression induction, once it provides significant information of the secondary effects of glucocorticoids administration in poultry.

Computerized auditory training (CAT) is a convenient, low-cost approach to improving communication of individuals with hearing loss or other communicative disorders. A number of CAT programs are being marketed to patients and audiologists. The present literature review is an examination of evidence for the effectiveness of CAT in improving speech perception in adults with hearing impairments. Six current CAT programs, used in 9 published studies, were reviewed. In all 9 studies, some benefit of CAT for speech perception was demonstrated. Although these results are encouraging, the overall quality of available evidence remains low, and many programs currently on the market have not yet been evaluated. Thus, caution is needed when selecting CAT programs for specific patients. It is hoped that future researchers will (a) examine a greater number of CAT programs using more rigorous experimental designs, (b) determine which program features and training regimens are most effective, and (c) indicate which patients may benefit from CAT the most.

When interacting on a learning task, which is typical of several academic situations, individuals may experience two different motives: Understanding the problem, or showing their competences. When a conflict (confrontation of divergent propositions) emerges from this interaction, it can be solved either in an epistemic way (focused on the task) or in a relational way (focused on the social comparison of competences). The latter is believed to be detrimental for learning. Moreover, research on cooperative learning shows that when they share identical information, partners are led to compare to each other, and are less encouraged to cooperate than when they share complementary information. An epistemic vs. relational conflict vs. no conflict was provoked in dyads composed by a participant and a confederate, working either on identical or on complementary information (N = 122). Results showed that, if relational and epistemic conflicts both entailed more perceived interactions and divergence than the control group, only relational conflict entailed more perceived comparison activities and a less positive relationship than the control group. Epistemic conflict resulted in a more positive perceived relationship than the control group. As far as performance is concerned, relational conflict led to a worse learning than epistemic conflict, and - after a delay - than the control group. An interaction between the two variables on delayed performance showed that epistemic and relational conflicts were different only when working with complementary information. This study shows the importance of the quality of relationship when sharing information during cooperative learning, a crucial factor to be taken into account when planning educational settings at the university.

Introduction.Coccygodynia is a multidisciplinary disease which is diffi cult to treat. It seriously limits the ability to work and signifi cantly affects the quality of life of patients. The study of somatic dysfunctions in patients with coccygodynia and the analysis of the results of osteopathic treatment of such patients makes it possible to justify the necessity of osteopathic correction of coccygodynia.Goal of the study— to determine the structure of the leading somatic dysfunctions in patients with coccygodynia and to study the effectiveness of osteopathic treatment of this pathology.Materials and methods.The study involved 44 patients from 25 to 65 years old, randomly divided into two groups. The main group of 24 people (20 women and 4 men) received osteopathic treatment, in accordance with the identifi ed leading somatic dysfunctions. Patients of the control group (16 women and 4 men) were treated locally with soft manual techniques (the treatment area was limited by the pelvic region). In order to assess the results of the treatment, we examined the intensity of the pain syndrome and the psycho-emotional state of patients. The severity of the pain syndrome was assessed in accordance with the visual analogue scale (VAS). The psycho-emotional state (with physical and mental components) was assessed with the help of the SF-36 quality of life questionnaire.Results.Somatic dysfunctions typical for patients with coccygodynia have been identifi ed. Osteopathic treatment has proven to be more effective in comparison with local manual therapy of coccygodynia both in early periods and in 3 months after the end of the treatment course.Conclusion.Osteopathic treatment of post-traumatic coccygodynia is effective, and can be recommended for treatment of such patients.
