Research has been carried out on the use of the symbiotic “Rumimaster” in balanced diets of highly productive cows in the conditions of the breeding plant “Kirovskaya meadow-bog experimental station”. The experiment was carried out on two groups of animals in the middle of lactation with a duration of 90 days. The inclusion of the feed additive “Rumimaster” in the diet of experienced cows contributed to an increase in the gross production of natural and 4% fat milk by 124.5 kg and 128.4 kg, the yield of milk fat and milk protein by 5.2 and 4.1 kg, respectively. … The differences between the groups for these parameters were in the range of 5.1-5.7%. The productivity of cows for 305 days of lactation in the experimental group was higher than in the control by 7.5%. The symbiotic “Rumimaster” promoted the activation of digestion processes, which was reflected in the increase in the time of feed consumption and the duration of the chewing gum. The cows of the experimental group showed an increase in the level of digestibility of the main nutrients. In terms of the digestibility of crude protein and crude fiber, the experimental group of cows significantly exceeded the indicators of the control group by 3.3 and 3 absolute percent, respectively. The blood biochemical parameters of the animals of the experimental and control groups were within the physiological norm. The economic evaluation of the research results showed the effectiveness of the use of the symbiotic “Rumimaster” in the diets of lactating cows, which was expressed in the receipt of additional profit from one cow in the amount of 1,344.79 rubles for the period of experience and an increase in the profitability of milk production by 2.1 absolute percent.
Применение имплантов в коррекции диафрагмальной грыжи у новорожденныхThe use of implants for surgical treatment of congenital diaphragmatic hernia in newborns Врожденная диафрагмальная грыжа (ВДГ) -патология, которая требует обязательной хирургической коррек-ции. При значительных дефектах диафрагмы, например аплазии ее купола, зачастую возникает необходимость в использовании имплантационных материалов. До сих пор нет единой точки зрения по вопросу выбора имплан-та. В статье представлены результаты сравнительного анализа лечения новорожденных (n = 40) с левосторонней ложной ВДГ. Всем пациентам была выполнена торакоскопическая пластика купола дифрагмы. По типу использо-ванного имплантационного материала детей разделили на две группы: для первой (n = 16) применяли синтетичес-кие импланты «Экофлон» («НПК "Экофлон"», Россия), для второй (n = 24) -биологические импланты Permacol (Tissue Science Laboratories, Великобритания). Результаты исследования показали преимущества биологичес-кого импланта: время операции при его использовании было меньше (106 мин против 144 мин при использова-нии «Экофлона», p <0,05); число рецидивов -также меньше (28 % против 54 %, однако p >0,05); случаев от-торжения импланта не было (при использовании «Экофлона» у двух пациентов началось воспаление, p <0,05).Congenital diaphragmatic hernia (CDH) is an absolute indication for surgical treatment. In case of extensive defects of the diaphragm, such as diaphragmatic aplasia, the use of implants is required. So far, there is no unanimous opinion on the type of the implant. The article presents a comparative analysis of treatment of 40 newborns with left pseuso-CDH. All patients received thoracoscopic repair of the diaphragmatic cupula. The patients were divided into two groups according to the type of the implant: 16 newborns received Ecoflon synthetic implants (Ecoflon Scientific and Production Complex, Russia) and 24 newborns received Permacol biologic implants (Tissue Science Laboratories, UK). The study demonstrated the advantage of the biologic implant over the synthetic one: the surgery took less time (106 minutes compared to 144 minutes with Ecoflon, p <0.05); relapses were also more rare (28 % and 54 %, respectively; however, p was >0.05); no implant rejection was observed (with Ecoflon, two patients responded with inflammation, p <0.05).Ключевые слова: новорожденные, врожденная диафрагмальная грыжа, торакоскопия, имплант, имплантационный материал, «Экофлон», Permacol
Purpose. Presentation of clinical cases of rare combination of omphalocele with pylorostenosis in the postoperative period and additional liver lobe. Materials and methods. In National Medical Research Center for Childrens Health of health surgical ward of newborns and infants for the 2019 us operated 2 children who performed surgery involving intra-operative decision making about further surgical tactics. Results. the results of surgical treatment of newborns with omphalocele combined with hypertrophic pylorostenosis and extra liver lobe are presented. Conclusions. In patients with malformations of the anterior abdominal wall in the postoperative period, when regurgitation syndrome appears, it is necessary to make a differential diagnosis between the functional and organic causes of obstruction. When confirming the organic nature of the obstruction, surgical intervention is indicated. It is necessary to be able to timely and objectively assess the risks and expediency of the approach when choosing surgical tactics in each individual case.
The results of long-term research on the use of drained lowland peat and developed soils in feed production in the North-East of the European part of Russia are presented. The main agroecological technologies for the production of high-quality feed in soil-protective crop rotations, long-term pastures on drained low-lying peat soils and methods for using developed peatlands in intensive haymaking mode are proposed.
Anorectoplasty and pull-through procedure can be performed with extended mobilization or tension anastomosis, which can compromise the vasculature of the rectum. We aimed to analyze the histopathological ndings, hypoxia biomarker values and to correlate the incidence of anal stenosis and defecation disorders of both conditions in experimental models. MethodsWe created anorectal reconstruction models during anorectal mobilization with extended mobilization with impaired vascularization (group I) and tension anastomosis (group II) in rats. Hypoxia biomarker values was assessed in both groups and in sham operated animals (group III). The histopathological changes on the 3 rd postoperative day, anal stenosis and defecation disorders on the 35 th day are compared with each other and with a control group (group IV). ResultsHypoxia biomarker levels con rmed postoperative ischemia in I -III groups compared to the control.Groups I, II are accompanied by pronounced histopathological changes in the anorectum on the 3rd postoperative day and accompanied by severe brosis on the 35 th day. In comparison to group III, both groups showed defecation disorders and anal stenoses. ConclusionExtensive mobilization with vascular impairment and tension anastomosis resulted in similar ischemia with histopathologic changes, which in the long term resulted in brotic changes associated with defecation disorders.
