The search for alternative drugs for treating inflammatory diseases of bacterial etiology in high yielding cows that do not cause antibiotic resistance and do not reduce the quality of the obtained products is an urgent task for veterinary obstetrics. As one of this remedy, the authors have tested ozonated flaxseed oil (OFO), obtained by bubbling flaxseed oil with an ozon-oxygen mixture for four hours by means of ceramic spray with the ozone concentration being 30 mg / liter. During the bacteriological studies, it was found out that a two-hour incubation of the drug with a bacterial culture inhibits the growth of Staphylococcus aureus and Escherichia coli at a dilution of 108 microbial bodies (m.b.) in ml, bacteria of the genus Citrobacter at a concentration of 106 m.b. and Streptococcus agalactiae at the dilution of 107 m.b. in ml. The therapeutic efficiency of OFO was evaluated on the basis of using it for the cows of the Kholmogory Holstein breed, with the signs of postpartum septic catarrhal endometritis. For this purpose, 2 groups of animals were formed on the basis of analogues. For treating the cows of the experimental group the OFO has been used, and the cows of the control group were treated with the antibiotic containing the drug tylosinocar. For 5 months of observation, all animals were fertilized in the control group, and in the group where OFO was used this number was 93.3 %. Moreover, in the experimental group 47 % of the cows were fertilized after the first insemination, which is 27 % more in comparison with the control group. The duration from calving to fertilization in the group where OFO was used averaged 104 days, which is 21 days less (P <0.05) compared to the control group. Studies have shown that the use of OFO did not lead to the inhibitors emergence in milk in the experimental group of cows.

Abstract Postpartum endometritis is one of the leading causes of infertility in cattle. The study aims to investigate the possibility of using ozonized flaxseed oil (OFO) for treating postpartum purulent-catarrhal endometritis in cows. Ozone was synthesized by using medical ozone generator and chemically pure oxygen. Linseed oil (400.0 ml) was bubbled with an ozone-oxygen mixture for 4 hours through a ceramic sprayer. An ozone concentration at the outlet was 30 mg/l. The therapeutic efficacy of OFO was studied on cattle of the Kholmogory breed with a productivity of 4800 - 5800 kg of milk per year. Thirty animals with symptoms of postpartum purulent-catarrhal endometritis were divided into two groups (n = 15). All of the subjects were in the second and third lactation periods. Animals from both groups were injected with 2% sinestrol solution on days 1 and 3 of treatment. OFO was used in the experimental group (EG). The cattle of the control group (CG) received a 7.5% solution of benzethonium chloride. Drugs were administered intrauterine at a dose of 50–150 ml (depending on the uterus’s size) using a polystyrene pipette, with an interval of 48–72 hours. Cows were inseminated artificially by the cervical method. The pregnancy was determined on the 30-35th day after insemination by ultrasonography. After 5 months of observation, all animals of the CG were pregnant. The pregnancy rate in the EG was 93,3%. In the groups efficiency of the first insemination was 20% and 47%, respectively. In the EG, one impregnation required 1.8±0.2 inseminations, which is 0.5 less than in the CG (2.3±0.3). The duration from calving to impregnation in cows in the EG was 104.4±6.9, 21.2 days less (P &lt; 0.05) than the control, where the period was 125.6±7.6. Thus, OFO can be effectively used for the treatment of endometritis in cattle.

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.

BACKGROUND Caring for children with cancer can be a stressful experience for parents and may have negative effects on their physical and psychological well-being. Although evidence has shown that resilience is associated with positive psychological well-being, few interventions have been specifically designed to enhance the resilience of parents of children with cancer. OBJECTIVE The aim of this study is to examine the effectiveness of a mobile device–based resilience training program in reducing depressive symptoms and enhancing resilience and quality of life (QoL) in parents of children with cancer. METHODS Parents of children diagnosed with cancer were recruited from the pediatric oncology wards of 3 tertiary hospitals in China. The participants were randomly assigned to either the experimental group (52/103, 50.5%) to undergo an 8-week mobile device–based resilience training program or to the control group (51/103, 49.5%) to receive an 8-week program of placebo information. The study outcomes included resilience, depressive symptoms, and QoL, as measured by the Connor–Davidson Resilience Scale, the Self-Rating Depression Scale, and the Short Form of the 6-Dimension Health Survey, respectively. All data were collected at baseline and at 2 and 6 months of follow-up. The data analysis followed the intention-to-treat principle. A generalized estimating equation was used to examine the effects of the intervention. RESULTS The participants were mostly female (72/103, 69.9%), and their mean age was 33.6 (SD 5.2) years. The participants in the experimental group showed significantly higher levels of resilience (mean 67.96, SD 15.8 vs mean 58.27, SD 19.0; <i>P</i><.001) and lower levels of depressive symptoms (mean 40.17, SD 9.9 vs mean 46.04, SD 10.9; <i>P</i><.001) than those in the control group at 6 months of follow-up. The intervention showed statistically significant effects in improving resilience (<i>β</i>=6.082; <i>P</i>=.01) and decreasing depressive symptoms (<i>β</i>=−2.772; <i>P</i>=.04) relative to the control group. The QoL score in the experimental group was higher than that in the control group at 6 months of follow-up (mean 0.79, SD 0.2 vs mean 0.76, SD 0.3; <i>P</i>=.07); however, no statistically significant intervention effect was detected (<i>β</i>=.020; <i>P</i>=.38). CONCLUSIONS The mobile device–based resilience training program effectively enhanced resilience and alleviated depressive symptoms in parents of children with cancer. It is highly recommended that health care professionals incorporate this resilience training program when providing psychological care to parents of children with cancer.

Even though student questioning is the key aspect of inquiry learning, students ask very few questions in Science classrooms. This research aimed to increase the number of high-level questions posed by primary students during science lessons. An experiment was designed in which the experimental group was taught about the taxonomy of questions that can be asked by students during a science lesson. The quality of selected student questions was discussed as a whole class throughout the implementation. In addition, the experimental group completed the textbook activities at the end of each section in groups, whereas, the control group finished these activities individually. The experiment lasted for 4 weeks (12 lessons), during the ‘Microscopic Organisms and Environment’ unit in two 4th-grade classrooms. After completing each section of the unit, student questions were collected. The questions were classified as either low-level or high-level questions. The findings showed that in the experimental group, there were significantly more high-level questions compared to the control group. The questions were longer and more comprehensive in the experimental group. In both groups, as students’ achievement increased, so did the number of questions they asked. Keywords: student questions, high-level questions, question taxonomy, primary science.

Generalized Anxiety Disorder (GAD) is one of the most common anxiety disorders. It has been reported that psychological treatments like Cognitive-Behavioral Therapy (CBT) is effective for patients with GAD. The purpose of the present research was to investigate the effectiveness of CBT on Quality of Life (QOL) and worry in patients with GAD. A sample of 30 patients with GAD who had been referred to psychiatry offices in Isfahan, Iran were selected and assigned into an experimental group (n=15) and a control group (n=15) randomly.  The experimental group received CBT in 8 weekly sessions. All participants completed the World Health Organization Quality Of Life-Brief (WHOQOL-BREF) questionnaire and the Penn State Worry Questionnaire (PSWQ) at pretest, posttest and follow up. The results of MANCOVA showed that the mean scores of QOL in the experimental group was significantly higher than the control group at the posttest and follow up (P<0.05) and the mean scores of worry in the experimental group was significantly lower than the control group at the posttest and follow up (P<0.05) It is concluded that CBT can be applied for the patients with GAD as a useful psychological treatment. In general, CBT can improve QOL and decrease worry in patients with GAD.

Social Annotation (SA) tools can be used to facilitate active and collaborative learning when students have to study academic texts. However, making these tools available does not ensure students participate in argumentative discussions. Scaffolding students by means of collaborations scripts geared towards collaboration and discussion encourages students to engage in meaningful, high-quality interactions. We conducted an experiment with students (n=59) in a course running at a Dutch university, using the SA tool Perusall. A control group received normal instructions, while an experimental group received scaffolding through collaboration scripts. The results showed a significant increase in the number of responses to fellow students for the experimental group compared to the control group. The quality of the annotations, measured on levels of Bloom’s taxonomy, increased significantly for the experimental group compared to both its baseline measurement and the control group. However, when scaffolding was faded out over subsequent assignments these differences became non-significant. The experimental groups’ increased quality of annotations did not remain over time, suggesting that internalization of the scripts was not achieved.

The problem of complete mineral and vitamin nutrition in rabbit breeding is relevant today, despite new discoveries, and research in this direction continues both in Ukraine and around the world. The paper presents experimental data from the results of research to study the effect of different doses of vitamin and mineral supplement "Tekro" in the diets of young rabbits on their productivity, slaughter quality and biological value of rabbit meat. The obtained data of body growth, massometric indicators of carcasses and internal organs of rabbits of experimental groups after slaughter indicate a positive effect of vitamin-mineral supplement "Tekro" on the intensity of development of the body and individual internal organs, which contributes to increased metabolic processes and weight gain in animals research groups. Feeding vitamin and mineral supplements to rabbits of experimental groups of the New Zealand breed for 45 days contributed to a better transformation of feed nutrients into products. In rabbits of the 3rd experimental group, which together with basic ration were fed 3.5 % of the premix "Tekro" at 90 days of age, the highest rates of body weight were recorded, which differed by 8.89 % compared to the control group. In a set of indicators that characterize the nutritional value of rabbit meat, we studied sensory indicators that characterize the quality of rabbit meat: taste, color, pH, juiciness, moisture content, elasticity, aroma, "marbling", etc. It was found that in the appearance of carcasses and muscles in the control group, the samples scored 8.4 points. In the 3-rd and 4-th experimental groups, the number of points on this indicator was higher by 1.2 %. The difference was a trend. Examining the aroma of meat, it was found that in the control of this indicator, the samples scored 7.8 points. In meat samples from experimental groups 3 and 4, the aroma was more identical to natural, so the samples received 2.6 % higher scores. Samples from 3 experimental groups scored the most points in terms of taste. Compared with the control, the figure was higher by 3.6 %. Examining the juiciness of rabbit meat, it was found that samples obtained from carcasses 2 and 3 of the experimental group tended to increase this indicator. Summing up the data, it was found that the highest overall score was found in meat samples from 3 experimental groups. The difference with the control was within the trend and amounted to 2.4 %. Feeding rabbits vitamin and mineral supplements to rabbits helps to obtain good quality meat products with high culinary properties. No data were available to support the effect of vitamin and mineral supplements on compound feed on the synthesis of toxic substances in muscle tissue or the deterioration of rabbit meat. The biological value of muscle samples from rabbits of the 2-nd experimental group did not differ from the control data. The increase was only 0.11 %. It was found that the biological value of muscle tissue from animals of the 4th experimental group was greater than in the control. The difference was 2.6 % Meat obtained from rabbits of the 3rd experimental group, which were fed compound feed with a content of mineral-vitamin supplement "Tekro" 3.5 %, in biological value outweighed the control indicators. The difference was not significant and amounted to 4.1 %. The use of different doses of vitamin and mineral supplements in the feed of young rabbits did not lead to significant changes in the quality of raw hides and furs.
