Impact of Siberian larch dihydroquercetin or dry distilled rose petals as feed supplements on lamb's growth performance, carcass characteristics and blood count parameters.

Abstract The objective of this study was to determine the impact of dihydroquercetin from Siberian larch and dry distilled rose petals (DDRP) on growth performance, carcasses quality and blood characteristics of lambs from the Bulgarian Dairy Synthetic population sheep. For the purpose of the study there were used 30 clinically healthy male lambs aged 65 days, levelled by live weight. They were housed in a totally indoor barn and were divided into one control and two experimental groups, each consisting of 10 animals that were fed for 50 days. The control group (C) was fed ground alfalfa + granulated compound feed. The experimental groups (D) and (R) were fed on the same diet supplemented either with 7.5 mg dihydroquercetin/kg/day or with 545 mg dry distilled rose petals (DDRP)/kg/day respectively. The experimental group D had 5.45% and 8.78% higher slaughter weight comparing to the control group C and experimental group R, respectively. The carcass yield of lambs supplemented with dihydroquercetin was 1.28% and 2.19% higher compared to control group C or the lambs that had consumed DDRP. The carcass yield of lambs having consumed dihydroquercetin is higher by 1.28% and 2.19% respectively compared to lambs from control group C or those having consumed DDRP. The carcass conformation of C or R groups lambs do not differ (70% - class P, 30% - class O). The 90% of lamb's carcasses from the experimental group D were classified in class P. No significant differences were found in the fatness degree. The dihydroquercetin feeding increases the relative fat content (P ≤ 0.01) of lamb carcasses but adversely affects their conformation. No significant differences (p > 0.05) were found between 1st h and 24th h post-mortem pH of control group C and experimental group D. Compared to them the pH values of the experimental group R were by 0.14 - 0.15 pH units lower (p ≤ 0.05). No significant differences (p > 0.05) were found in the blood count of the three studied groups of lambs. Exceptions were made for erythrocytes (RBC) and haemoglobin (HGL) in the experimental group D which were higher (p ≤ 0.05) than these in control group C and experimental group R. The conclusion made was that the use of the dihydroquercetin had a positive effect on the lamb's fattening, slaughter weight and carcass yield. Such an effect was not detected when DDRP was used.

Abstract Improving pig growth performance, nutrient digestibility and pork quality is a continual goal of the pig breeding. For this reason, an increasing interest in using phytonutrients has been observed recently. The objective of this study was to determine the impact of Larix sibirica dihydroquercetin or dry distilled Rosa damascena petals on growth performance, carcass composition, meat quality, blood characteristics and histological changes in ovaries and liver in native Danube White fattening pigs. A total of 120 pigs were used in the experiment with duration of 45 days prior to harvest. The pigs were divided into five groups. The control group (C) was fed basal diet. The other four experimental groups were fed with the same diets containing either 3.5 or 7.5 mg dihydroquercetin/kg/d and 0.255 or 0.545 g dry distilled rose petals/kg/d. The supplementations with dihydroquercetin or dry distilled rose petals increased average body weight by 7.74-9.05%, average daily gain by 27.06-30.13%, and feed to gain ratio by 12.53-15.99% and decreased feed consumption by 5.24-13.84% and average liver weight by 10.53-21.12% compared to the control group. Two supplementations didn't cause pathological changes in histological structure of pigs' liver and ovaries, and didn't influence pH values and proximate composition of m. Longissimus thoracis and m. Semimebranosus. No pH determined stress-induced muscle damage was found and the pork carcasses were classified in classes E and U. The two used supplements reduced the blood LDL cholesterol by 13.27-14.29% as well as increased erythrocytes, platelets, haematocrit, mean red blood cell count, mean haemoglobin concentration in erythrocytes, triglycerides and total cholesterol.

Introduction:Psychological impact of Therapeutic Patient Education (TPE) for dialysis patients is rarely evaluated since the focus of many studies is on medical variables (i.e., adherence).Objectives:The aims of this study were: 1) to estimate the impact of a TPE program on knowledge, depression and anxiety, 2) to examine change in knowledge as a mediator of the effects of a TPE program on mental health.Method:This study was conducted in three hemodialysis units and comprised two groups: an experimental group with education and a control group with routine care. The program was based of 5 educative sessions. Knowledge, depressive and anxious symptoms were assessed with self-reported outcomes measured before and 3 months after the program.Results:The sample comprised 125 patients. Knowledge about vascular access and nutrition (p < 0.01) and depressive symptoms increased in the experimental group (p < 0.01). Analysis of mediation showed that changes in knowledge about vascular access were a significant mediator of the effects of the program on depressive symptoms (F = 4.90;p = 0.01).Discussion:Knowledge acquired during an educational program could lead to an emotional change. Improving knowledge often leads to an awareness of the risks that can modify the psychological state of patients by reminding them of their vulnerability. This study shows that it is required to be attentive to the way of transmitting knowledge. It’s necessary adapting this transmission to the needs of patients and promoting the acquisition of psychosocial competence too.Conclusion:This study shows that knowledge acquired during an educational program can lead to an emotional change in the short term. A long-term follow-up of the population should be interesting to observe these emotional effects.

Summary. The disbalanced feeding and the uneven distribution of micro- and macroelements in the environment leads to a trace element, in particular hypomelanosis. To accelerate the growth and preservation of young farm animals include in the diet of various biological additives and drugs, which include selenium. For stimulation of weight gain in the livestock industry, as well as for the prevention and treatment of pathological processes in addition to micro - and macrouse amino acids, primarily methionine. The aim of this work was to study the influence of composition of DAFS-25+Polizon on morpho-biochemical parameters of blood and functional state of the liver in fattening bulls of black-motley breed in the conditions of the Republic of Bashkortostan. Experiments using were conducted on bull-calves of black-motley breed of the properties in the properties age from 6 to 15 months. The first experimental group during the experiment was additionally given the composition of DAFS-25+Polizon at a dose of 2 mg/kg, the animals of the control group received a standard diet. To assess the impact of the composition DAFS-25+Polizon on metabolism cattle studied morphological and biochemical indicators of blood and conducted histological examination of the liver. It is established that the use of the composition of DAFS-25+Polizon at a dose of 2 mg/kg increases the number of erythrocytes and hemoglobin in the experimental group and reduces the amount of white blood cells. The serum content of total protein, phosphorus and calcium increases in the group of experimental animals. Microscopic examination of the liver revealed no changes in the structure of the organ and hepatocytes in the experimental group, whereas in the control group hemodynamic disorders and dystrophic changes in liver cells were observed. Thus, the use of the composition DAFS-25+Polizon at a dose of 2 mg/kg of live weight in fattening bulls black-and-white breed contributes to the increase of redox processes in the body, stimulation of metabolism, prevent the development of liver disorders of cellular mechanisms of metabolism, optimizes the structure of the liver, which generally provides higher productivity.

Изучены рост и развитие бычков — помесей красной степной с казахской белоголовой породой в равнинной провинции Дагестана. Установлено, что помесный молодняк, по сравнению с чистопородным скотом красной степной породы, имеет более высокую живую массу при рождении на 1,8 кг, или 7,3%. При отъеме в 8-месячном возрасте помеси имели живую массу 210 кг против 187,6 кг у красного степного молодняка, что на 22,4 кг, или 11,9% выше. В 12-, 15- и 18-месячном возрасте живая масса помесных бычков равнялась 291,8 кг, 359,7 и 436,6 кг, соответственно, или на 28 кг, 36 и 45,8 кг больше по сравнению с красным степным скотом. Среднесуточные приросты помесных бычков за период выращивания и откорма составили 760 г, что выше на 12,1% по сравнению с чистопородным красным степным молодняком. После заключительного откорма и убоя помесные бычки дали тяжеловесные туши с хорошим поливом. По массе парной туши они превосходили чистопородных аналогов на 31,3 кг, или 15,6% с преимуществом выхода туши на 2,4%. Убойный выход у бычков опытной группы составил 58,7%, контрольной — 55,8%. От помесных бычков были получены тяжеловесные шкуры массой 27,1 кг, от чистопородных — 21,6 кг, преимущество по этому показателю имели помесные животные 5,5 кг, или 25,4%. Для увеличения производства говядины в равнинной провинции Дагестана рекомендуем скрещивание коров красной степной породы с быками казахской белоголовой породы. The growth and development of bulls of red steppe crossbreeds with the Kazakh white-headed breed in the flat province of Dagestan were studied. It was found that young crossbreed animals in comparison with purebred red steppe cattle have a higher live weight at birth by 1,8 kg or 7,3%. When weaning at 8 months of age, cross-bred bulls had a live weight of 210 kg against 187,6 kg in red steppe young, which is 22,4 kg, or 11,9% higher. At 12, 15 and 18 months of age, the live weight of crossbred bulls was 291,8 kg, 359,7 and 436,6 kg, respectively, or 28 kg, 36 and 45,8 kg more than the red steppe cattle. The average daily growth of cross-bred bulls during the growing and fattening period was 760 g compared to 678 g, that is, they were 12,1% higher compared to purebred red steppe young. After the final fattening and slaughter, the cross-bred bulls gave heavy carcasses with good watering. By weight of the paired carcass, they were superior to purebred counterparts by 31,3 kg or 15,6% with an advantage of 2,4% carcass yield. The slaughter yield of bulls in the experimental group was 58,7%, 55,8% in the control group, respectively, with an advantage in favor of crossbreeds of 2,9%. Heavy skins weighing 27,1 kg were obtained from crossbreed bulls, 21,6 kg from purebred ones, and crossbreed animals of 5,5 kg or 25,4% had an advantage in this indicator. Studies have shown that in order to increase beef production in the lowland province of Dagestan, it is necessary to use crossbreeding of the breeding stock of the red steppe breed with bulls of the Kazakh white-headed breed.

Since the occurrence of swine salmonellosis has increased over time and control strategies other than biosecurity are highly recommended, the present study aimed to evaluate the efficacy of vaccination with Salmonella Choleraesuis and Salmonella Typhimurium bacterins in pigs. Two experimental groups were formed: G1, animals immunized with two doses of a commercial vaccine (n = 20); G2, control group (n = 20). After vaccination, all pigs were orally challenged (D0) with 108 CFU of Salmonella Typhimurium and evaluated for 40 days. Every 10 days after D0, five piglets from each experimental group were euthanized and submitted to the necroscopic examination, when organ samples were collected. Blood samples and rectal swabs were collected before the first dose of the vaccine (D−42), before the second dose (D−21), before the challenge (D0), and thereafter, every three days until D39. Blood count, serum IgG measurement by ELISA, and the excretion of Salmonella Typhimurium in feces were evaluated. While the results from blood count and serum IgG concentration did not differ, the detection and excretion of Salmonella between G1 and G2 differed (p < 0.05). Therefore, it was observed that this vaccine partially protected the animals against experimental infection with Salmonella Typhimurium, reducing the excretion of bacteria in feces.

Writing is an intricate process that encompasses various factors and is a key skill for English as a Foreign Language (EFL) students. Thus, writing assignments are vital for any curriculum. One of the essential aspects of effective writing includes good grammar knowledge. Advocates of process writing argue that a free-writing journal is a practical approach to teaching EFL students writing. This study is intended to examine the impact of the free-writing journal on EFL learners. This study was conducted on 80 students from a writing course at the University. Thirty-five students were randomly selected to join the free-writing program—the experimental group—and 45 students were kept in their regular structured writing program—the control group. The experimental group selected topics of interest to them and was encouraged to write in English freely without concern for errors, whereas the control group followed a regular structured writing program where the topics were selected for them and they wrote following a clear guideline. Five major areas were investigated to evaluate students’ progress: the number of words written, spelling, capitalization, subject-verb agreement, and punctuation. The researcher conducted semi-structured interviews with 10 students of the experimental group to elicit their perception of the free-writing program. According to the analysis, students in the free-writing program acquired better grammar acquisition than the control group. The researcher also observed students’ perception of free-writing at the end of the study and found that free-writing improved their writing skills.

AbstractWriting as a multiple-step process is one of the most complex and demanding skills for graduate students to master. Foreign or second language learners who are required to write for academic purposes at the university level may even find it more demanding to master. One of the ways of decreasing the burden of mastering this skill for learners is mediation, using scaffolding techniques to teach writing. Hence, having a good understanding of the impact(s) of adopting mediating or scaffolding techniques in writing classes is absolutely indispensable. To this end, the present study employed an experimental research design to investigate the impact of mediation in the flipped writing classrooms of the students of medicine. To peruse this goal, 47 medical students were selected through purposive sampling and put into control and treatment groups. Medical students in the treatment group watched teacher-made video content(s) before their writing classes. The students in this group experienced organized-interactive writing group activities in their classes. Unlike the experimental group, the students in the control group received all the instructions in the classroom and were assigned homework. The findings obtained through the ANOVA and t-test indicated that the students in the experimental group significantly outperformed their counterparts in the control group in terms of their writing. A probable conclusion could be that by requiring students to study in advance and take responsibility for their learning, flipped classroom can provide the opportunity for learners to actively construct knowledge rather than receive the information passively in the classroom. Flipped classroom can also cultivate interactive class time for teachers and enable them to invest in more fruitful academic practices, instead of asking students to spend a substantial amount of time each week doing homework independently.
