Проблема и цель. Целью исследований стало изучение терапевтической эффективности комплексной терапии хронической обструктивной болезни бронхов и легких (ХОББиЛ) у лошадей и экономическое обоснование лечения. Методология. Научно-исследовательская экспериментальная работа проводилась на базе конюшни ИП Дубеев А.И. Малоярославецкого района Калужской области, ООО «Старожиловский конезавод», КСК «Успенский» Скопинского района, а также на базе частных конюшен Рязанской области в период с 2017-2019 гг. Объектом исследований являлись лошади с диагнозом ХОББиЛ. В процессе научной работы были собраны данные о распространении и манифестации ХОББиЛ на поголовье 16 лошадей различных пород, возраста и пола. На основании клинических и субклинических симптомов изучаемой патологии были составлены две схемы лечения ХОББиЛ у лошадей. В сравнительном аспекте изучена их терапевтическая эффективность, предоставлено экономическое обоснование терапии. Для этого были сформированы две аналогичные по диагнозу (ХОББиЛ) группы лошадей (n=8): контрольная и опытная. Результаты. Установлено, что заболеваемость лошадей ХОББиЛ за период с 2017 по 2019 годы составляет от 2,0 до 11,7 %. Установлена тенденция увеличения на 4,4 % случаев ХОББиЛ в 2019 году по сравнению с 2017 годом. Выявлено, что наивысший процент ХОББиЛ (53 %) наблюдался у животных старшей группы (16-19 лет). На протяжении периода наблюдения изучаемая патология в 75 % случаев была отмечена у жеребцов, в 25 % – у кобыл. Изучением манифестации проявления ХОББиЛ выявлено, что наиболее часто встречающимися симптомами во время приступов были: снижение работоспособности, снижение упитанности, абдоминальный тип дыхания, экспираторная одышка, увеличение частоты дыхания и сердцебиения в 100 %; западение межреберных промежутков, запальный желоб, выпячивание анального отверстия («игра анусом») – в 70 %, изменение пищевого поведения в 60 %, носовое истечение в виде густой катаральной пены в 50 % и лихорадка в 10 % случаев болезни у лошадей. Разработана эффективная комплексная схема терапии лошадей с ХОББиЛ. Заключение. Установлено, что при применении комплексного лечения ХОББиЛ у лошадей, включающего коррекцию условий содержания, внесение в рацион кормовых добавок «Equimins Clear Breather Supplement» и «Льняного масла», а также применение фармпрепаратов (дексаметазона, спутолизина, ингаляции беродуала) терапевтическая эффективность в опытной группе составила 87,5 %, что выше показателя контрольной группы на 12,5 %. Срок клинического выздоровления в опытной составил 9,8 суток, в контрольной группе 17,6 суток. Стоимость лечения ХОББиЛ в расчете на лошадь массой 500 кг составила 30530 руб., что в 2,2 раза больше чем в контроле. Однако это дорогостоящее лечение экономически обосновано, так как позволяет снизить сроки достижения ремиссии в 1,8 раза. Problem and goal. The aim of the research was to study the therapeutic effectiveness of complex therapy of chronic obstructive pulmonary disease (COPD) in horses with and provide an economic justification for treatment. Methodology. Research work was carried out on the basis of IP Dubeev A. I. Maloyaroslavetsky district of the Kaluga region, LLC "Starozhilovsky Stud Farm", KSK "Uspensky" of the Skopinsky district, as well as on the basis of private stables of the Ryazan region in the period from 2017-2019. The object of research was horses with a diagnosis of COPD. In the course of scientific work, data were collected on the manifestation of hobbils on the livestock of 16 horses of various breeds and ages. Based on the clinical and subclinical symptoms of the studied pathology, two treatment regimens for COPD in horses were compiled. In a comparative aspect, their therapeutic and economic effectiveness is studied. For this purpose, two groups of horses (n=8) similar in diagnosis (COPD) were formed: a control group and an experimental group. Results. It was found that the incidence of COPD horses for the period from 2017 to 2019 is from 2.0 to 11.7 %. The trend of an increase of 4.4% in cases of COPD in 2019 compared to 2017 was established. It was revealed that the highest percentage of hobbits (53 %) was observed in animals of the older group (16-19 years old). During the follow - up period, the studied pathology was observed in 75% of cases in stallions, and in 25% in mares. Studying the manifestation of the manifestation of COPD, it was revealed that the most common symptoms during seizures were: decreased performance, decreased fatness, abdominal type of breathing, expiratory shortness of breath, increased respiratory rate and heartbeat in 100 %, occlusion of the intercostal spaces, the ignition chute, protrusion of the anal opening ("playing with the anus") - in 70 %, changes in eating behavior in 60 %, nasal discharge in the form of thick catarrhal foam in 50% and fever in 10% of cases of the disease in patients with An effective comprehensive treatment regimen for horses with COPD has been developed. Conclusion. It was found that when using complex treatment of COPD in horses, including correction of conditions of detention, introduction of feed additives "Equimins Clear Breather Supplement" and "Linseed oil" into the diet, as well as the use of pharmaceuticals (dexamethasone, sputolysin, berodual inhalation), the therapeutic effectiveness in the experimental group was 87.5%, which is 12.5% higher than in the control group. The period of clinical recovery in the experimental group was 9.8 days, in the control group 17.6 days. The cost of treatment of COPD per horse weighing 500 kg was 30530 rubles, which is 2.2 times more than in the control. However, this expensive treatment is economically justified, as it reduces the time to achieve remission by 1.8 times.

The objective of the work was to determine the possibility of drug correction of endothelial dysfunction, structural changes in peripheral arteries and the synthesis of end products of nitric oxide metabolism by the use of a combination of roflumilast and quercetin in the baseline therapy. In contrast to the baseline, the use of integrated therapy was followed in 6 months by a probable increase in the initial rate by 18.76 % (0.61 ± 0.04) m/s to (0.75 ± 0.04) m/s (t = 2.47; P < 0.05) and a probable decrease in the initial diameter of the brachial artery to (3.69 ± 0.29) mm (t = 2.49; P < 0.05). Patients of the experimental group have shown a significant increase in mean values of EDVD at the end of in-patient treatment and after 6 months of intensive supportive therapy (t = 2.17; Р < 0.05). The appointment of complex therapy after 6 months showed an increase in concentration in the blood of metabolites of NO in 1,3 times to (10.35 ± 1.89) μmol/l (t = 1.00; P > 0.1) at normal (12.05 ± 2.11) μmol/l. In patients of the index group after six months of the background therapy, IMT index has appeared in 1.07 times lower than the input data and has not reached the level of the control group. The IMT index for patients in the experimental group was considerably lower than the index before treatment (t = 0.31; P > 0.1).  Application of complex therapy in patients with severe chronic obstructive pulmonary disease in the exacerbation phase in combination with stable coronary heart disease, stable angina pectoris I–II FK contributes to the restoration of endothelial function, improves structural changes in the peripheral arteries and has a stimulating effect on the synthesis of nitric oxide.

Mineral Feed Additives

Animals imported to Yakutia from other regions fall into feeding and housing conditions that differ from their usual agro-climatic conditions, which causes the problem of their adaptation. Yakutia is one of the areas where the feed of its own production has a lack of basic minerals, which affects the health and productivity of animals, which has an additional negative influence on the adaptation process of imported cattle. In order to replenish macro- and microelements in the body, it is necessary to introduce various local mineral feed additives, premixes, and use mineral salts into the ration. Under the conditions of Central Yakutia the influence of local mineral feed additives (zeolite of the Khonguruu Deposit in the Suntar district and sapropels of local lakes) containing macro- and microelements that increase the meat productivity of steers has been studied. As a result of the research the influence of local mineral feed additives on meat productivity and physiological condition of Hereford steers has been established. Influence of zeolite and sapropel in a complex with mineral salts on digestibility of nutrients of the ration and use of nitrogen, calcium and phosphorus by experimental animals has been defined. The influence of feed additives on the quality of meat products has been studied. The results have shown that the use of local mineral feed additives in the composition of ration of steers during the fattening period at a dose of 0,7 g zeolite per 1 kg of live weight of the animal and 200 g of sapropel in combination with 10 g of mineral salts contributed to the gain in live weight, carcass weight, carcass yield, yield of edible parts, and economic efficiency of fattening. For the entire period of the experiment the gain in live weight in groups was: in control group 2222,9 kg, in the 1st experimental group 2396,2 kg, in the 2nd experimental group 2471,1 kg. The total economic effect for the 1st experimental group for the period of experiment amounted to 44,3 thousand Rubles, for the 2nd experimental group 78,0 thousand Rubles or per 1 head/day 14,06 and 24,76 Rubles, respectively.

Mycotoxins have been formed in feed are secondary metabolites of fungi and are quite stable substances that have teratogenic, mutagenic and carcinogenic effects. An effective way to combat mycotoxins in feed is the use of feed additives that adsorb toxins, prevent their absorption in the gastrointestinal tract of the animal and are excreted from the body. The infl uence of coconut enterosorbent Shelltic Es on fattening and meat qualities of young pigs has been studied. It has been found in the process of fattening that the highest feed digestibility was in pigs of the experimental group, in the diet of which enterosorbent has been added. The results of studies of the chemical composition and technological properties of pork have been provided. The positive eff ect of enterosorbent on precocity, absolute average daily gain of live weight and reduction of feed expenditures per 1 kg of gain has been revealed. In pigs from the experimental group the average thickness of the fat was higher and the area of the “muscle eye” was lower compared with animals of the control group, which indicates that higher rates of carcass yield have been obtained due to faster accumulation of fat tissue. The weight of internal organs of pigs indicates the intensity of metabolic processes in the body. In experimental animals the weight of the lungs was 0,1 kg lower, and the liver and heart were higher by 0,13 and 0,01 kg, respectively. Enterosorbent had no effect on the content of vitamins in the liver of pigs of the compared groups. The content of impurities of organochlorine toxicants and toxic elements in the meat and liver of animals of the experimental group was lower than that of control analogues. Therefore, the use of enterosorbent Shelltic Es promotes more active excretion of them from the body.

The results of researches on the development of new mineral feed additives based on raw materials produced by Uralchem and the study of the eff ectiveness of their use in the rations of lactating cows have been presented in the article. The experiment has been carried out in the conditions of LLC “PF Barabinskoe” in the Dalmatovsky area in the Kurgan region where 3 groups of lactating cows of Black-and-White breed have been formed. Animals in the control group have been received the ration adopted in the farm, the 1st experimental group with the additive RusMA No. 1 at a dose of 150 g, the 2nd experimental group– with the additive RusMA No. 2 at the dose of 350 g. The use of experimental mineral additives in feeding lactating cows allowed us to increase their milk productivity and profi tability of production. At the same time, the best eff ectiveness was shown by the additive RusMA No. 2 at the dose of 350 g/head/day. The use of RusMA additives during the experiment period (105 days) allowed to increase the milk productivity of cows in the 1st experimental group by 6,03 % and in the 2nd experimental group by 8,24 %. Taking into account the fat content in milk, this diff erence was 6,31 and 8,53 %, respectively. The energy value of milk from cows of the experimental groups was higher compared to the control group by 2,45 and 1,76 %, respectively. According to the content of dry matter in milk, cows of the 2nd experimental group exceeded the control and 1st experimental group by 0,39 and 0,12 abs.%, respectively. The maximum milk fat content has been observed in the milk of cows of the 1st experimental group by 0,03 and 0,01 abs.% more than in the control and 2nd experimental groups, respectively. In terms of protein content, the cows of the 2nd experimental group signifi cantly exceeded the control group by 0,10 abs.% and the 1st experimental by 0,04 abs.%. The content of milk sugar in the 2nd experimental group was higher than in the control by 0,30 abs.% and compared to the 1st experimental by 0,11 %. Signifi cantly more calcium and phosphorus were contained in the milk of cows of the 2nd experimental group by 4,58 % (Р ≤ 0,001) and 2,86 % (Р ≤ 0,05), compared with the control group. The expenditures of feed in the EFU for the production of 1 kg of milk in animals of the 2nd experimental group was less by 5,13 % than in control cows and by 2,63 % compared to the 1st experimental group. The prime cost of 1 centner of milk was lower in the 2nd experimental group by 3,94 %, in the 1st experimental group by 2,65 % compared to the control group. The level of profi tability of milk production in the 2nd experimental group was higher by 9,0 and 1,0 abs.% in comparison with the control and 1st experimental groups, respectively.

The aim of this study was to compare the effect of two different types of oils in diet on the fatty acid profile in the eggs of layers and to include a particular type of oil as a supplement of feeding mixtures for layers in order to support the development of functional foodstuffs. Thirty layers fed a diet containing soybean oil constituted the control group (soybean oil is the most frequently used oil added to feeding mixtures). In the experimental group (thirty layers), soybean oil was replaced with linseed oil at the same amount (3 kg of oil per 100 kg of feeding mixture). Feeding was provided ad libitum for all days of the month. After one month, egg yolks were analysed and the fatty acid profile was compared. Significant differences (P ≤ 0.05) were found in the concentration of myristic acid that belongs to the group of saturated fatty acids. Eggs in the experimental group showed higher concentrations of myristic acid compared to the control group (0.20 g/100 g of fat and 0.18 g/100 g of fat, respectively). Highly significant differences (P ≤ 0.01) were found for heptadecanoic acid but the trend was opposite to that of myristic acid; concentrations of heptadecanoic acid in the experimental group were lower than those in the control group. Highly significant differences (P ≤ 0.01) were found for n-9 monounsaturated fatty acids where egg yolks in eggs from layers fed linseed oil contained higher concentrations of oleic acid, myristoleic acid, and palmitoleic acid. Lower concentrations of n-6 fatty acids (P ≤ 0.01) were found after the addition of linseed oil in eggs. Linseed oil showed a positive effect on n-3 fatty acids (α-linolenic acid), its concentration in the control and experimental group was 0.82 g/100 g of fat and 5.63 g/100 g of fat, respectively. The possibility of influencing the fatty acid profile in eggs is very important for the development of functional foods.

Increasing the production of pork meat requires careful work not only in terms of breeding, but also in the organization of complete feeding of animals, the correct selection of feed and feed additives containing the necessary nutrients. The purpose of the work was to analyze the use of premix in feeding young pigs on fattening. Two groups of fattening young pigs (Large White×Landrace) have been selected for the researches using the method of analogous groups, taking into account the breed, age, and live weight per 20 heads in each group with a live weight of 35 kg. Pigs of the control group have received the main economic diet, and animals of the experimental group have received an additional premix Khutorok at the rate of 10 g of premix per 1 kg of feed. The results have shown that the best age to reach 100 kg was in the experimental group of pigs – 215,8 days, which received premix with feed that characterizes their higher precocity by 36,3 days (P < 0,001) than in the control group of animals. The use of this premix had a positive impact on the livability of young animals, in the experimental group it was by 9,3 abs.% more than in the control group of animals. Thus, the best fattening traits have been possessed by young pigl of the experimental group have been received the premix Khutorok in their diet at the rate of 10 g of premix per 1 kg of feed. The obtained data indicate the feasibility of using the premix Khutorok in the feeding pigs for fattening.

In order to study the effect of dietary supplement of linseed oil on polyunsaturated fatty acids (PUFAs) in egg yolk of Gallus domestiaus, total 160 healthy Gallus domestiaus of 26-week old were randomly selected and divided into 4 groups, each of which included 40 chickens fed outdoors with an area of 63 m2 and free food and drinking water. The control group (CK) was fed the basic diet, and the experimental group was added 1, 3 and 5% of linseed oil in the fundamentals of diet (experimental group 1, 2 and 3, abbreviated as P1, P2, P3), respectively. The content of PUFA and the value of n-6 PUFA and n-3 PUFA in egg yolk were determined by gas chromatography with 24 eggs randomly selected in each group after 10th, 25th and 40th days of the commence of the experiment. We found that the levels of α-linolenic acid (C18:3n3, ALA) and docosahexaenoic acid (C22:6n3, DHA) in egg yolk were clearly higher than the CK when 3% linseed oil or 5% linseed oil were added in the diet during the three experiment periods, in which the contents of linoleic Acid (18:2n6c, LA) and arachidonic acid (C20:4n6, ARA) in egg yolk differ little between P1, P2 and P3 and the CK while the value of n-6 PUFA and n-3 PUFA in egg yolk of the P2 and P3 groups decreased significantly. The comprehensive comparisons suggested that the content of C18:3n3 and C22:6n3 in egg yolk could be clearly increased in the P2 while the value of n-6 PUFA and n-3 PUFA decreased. This study provides theoretical basis for the production of functional eggs enriched with C22:6n3 and C18:3n3.

Determining which forms of mineral feed additives can increase farm animal productivity is a key area of research. This study assessed the mineral composition of ruminal fluid and the effectiveness of calcium and phosphorus used by animals after the introduction of finely dispersed particles (FDP) of SiO2 (group I) and FeCo (group II) with a hydrodynamic radius of 109.6 ± 16.6 and 265 ± 25 nm, respectively. The deposition and use of calcium and phosphorus in the body of the experimental animals exceeded the control values. In group I, 30.8% more calcium was deposited (p ≥ 0.05), and in group II, the value was 30.3% (p ≥ 0.01). In the experimental groups, the calcium utilization rate was 27.3% higher in group I (p ≥ 0.05), and 28.2% higher in group II (p ≥ 0.01) compared to in the control. Phosphorus deposition was 34% higher (p ≤ 0.01) in experimental group I and 6% higher in experimental group II, compared with the control. Group I had a high utilization rate of phosphorus from the feed (with a 29% difference compared to the control). Comparison of the experimental groups revealed that the introduction of SiO2 FDP promoted an increase in the concentration of silicon, phosphorus, and calcium in the ruminal fluid. The introduction of FeCo FDP was accompanied by a decrease in the concentration of iron and cobalt in the ruminal fluid. Thus, the use of feed additive in finely dispersed form in the diet of animals was accompanied by an increase in the use of calcium and phosphorus by the animal’s body, which is advisable when intensifying milk and meat productivity. The obtained results require further research. Keywords: finely dispersed forms of microelements, ruminants, calcium and phosphorus exchange, feeding

Abstract Objective The purpose of this study was to investigate the effectiveness of elastic resistance training on improving muscle strength, functional exercise capacity, health-related quality of life (HRQoL), and dyspnea in people with stable chronic obstructive pulmonary disease (COPD). Methods For this systematic review, PubMed, The Cochrane Library, Embase (OVID), PEDro, SciELO, and CINAHL were searched from inception to November 2019. Included studies were randomized clinical trials in which people with stable COPD were allocated to (1) an experimental group that received lower-limb resistance training, upper-limb resistance training, or both using elastic resistance; or (2) a control group that received no or sham resistance training or conventional resistance training using weight machines. Data extraction was performed by 3 review authors. The methodological quality of the studies was assessed using the PEDro scale. Eight studies on 332 participants were included. Results Knee extensor strength was higher in the experimental group (standardized mean difference = 0.52, 95% CI = 0.09–0.95) compared with the non-exercise control group. Compared with the conventional exercise control, the experimental group presented similar effects for muscle strength, functional exercise capacity, HRQoL, and dyspnea (95% CI overlapped the line of no effect for all). Conclusions Elastic resistance training improves muscle strength in people with COPD. The current review suggests elastic resistance as a potential alternative to conventional resistance training using weight machines, as they show similar effects on muscle strength, functional exercise capacity, HRQoL, and dyspnea. Impact Due to its beneficial effects, including reduced risk of exacerbation-related hospitalizations, exercise training is viewed as the cornerstone of pulmonary rehabilitation in people with COPD. This study shows that elastic resistance training can be an effective, portable, practical, and low-cost alternative to conventional weight resistance training. Lay Summary Training with elastic resistance tubes or bands—which are easy to carry, easy to use, and relatively low cost—can be an effective way to improve strength for people with COPD and promote similar benefits to those achieved with weight machines.
