The article compares the reproductive qualities of sows of Danish selection obtained by different breeding methods during their seven farrowings in one farm. It was found that local sows F1 obtained from mothers of Landrace breed and boars of Danish Large White breed had a significant excess of the total number of piglets at birth over analogs obtained by backcrossing of two-breed sows with boars of Danish Landrace breed by 0.90 head or 5.92 % (p<0,001). Both purebred sows of Danish Landrace and local sows significantly exceeded their peers obtained by the method of backcrossing by the number of stillborn piglets by 1.17 heads or 45.88% (p<0.001) and 0.5 heads or 26.60% (p<0.001) respectively. The probable lag of sows obtained by backcrossing in terms of the proportion of stillborn piglets from both purebred analogs by 5.03% (p<0.05) and from local analogs – by 9.29% (p<0.05). The complex indicator of reproductive qualities, calculated as an evaluation index, showed that the best such qualities were possessed by livestock for purebred breeding, where animals scored 0.05 and 0.74 points more than their peers F1 and Fr, respectively. The calculation of the estimated selection index of reproductive qualities of sows allowed to state that sows obtained from backcrossing had a higher value of 109.66 points, which is more than their purebred peers – by 4.48 points and local peers – by 3.96 points. According to the results of the first farrowing, a significant difference in the total number of piglets at birth, fertility, number of piglets at weaning, safety, nest weight at weaning, the weight of 1 head at weaning between livestock groups is not established but found that purebred sows relative to analogs obtained from backcrossing had a significantly higher number of stillborn piglets by 0.75 head or 60.00% (p<0.01) and the proportion of stillborn piglets by 5.09% (p<0.01). Evaluation of the data of the second, fourth, fifth and seventh farrowings revealed no significant difference in the bulk of the indicators of reproductive qualities of sows between the livestock of all groups. The study of the third farrowing allowed claiming that the number of stillborn piglets in this period was probably higher in sows of the first control group relative to analogs of the second experimental (F1) by 0.73 heads or 31.88% (p<0,05) and relative to analogs Experimental III (Fr) by 0.97 heads or 42.36% (p<0.01). According to the sixth farrowing piglets of the II experimental group (F1) exceeded the number of births by 1,77 heads or 12.46% (p<0.05) – control analogs, the fertility rate – by 2.32 heads or 19.66% (p<0.01) – analogs of the control and 1.41 head or 9.99% (p<0.05) – analogs of the III experimental group (Fr), but at the same time inferior in terms of safety to peers of the control group by 13.25% (p<0.01). Intergroup analysis of data showed that during the sixth farrowing piglets of the II experimental group (F1) exceeded the fertility rate – by 2.32 heads or 19.66% (p<0.01) – control analogs and 1.41 heads or 9.99% (p<0.05) – analogs of the III experimental group (Fr). The study of the dynamics of absolute, average daily, and relative growth of piglets revealed that both in the control group (purebred Danish Landrace) and in the third experimental group (Fr) in terms of seven farrowings, the indicators did not differ statistically. However, piglets of group II (F1) during the sixth farrowing had the highest values: the absolute increase was 6.18 kg, exceeding the first by 0.58 kg or 10.36% (p <0.05), the average daily gain – 221 g, which is higher than the average for the first farrowing in the group by 20 g or 10.50 % (p<0.05) and a relative increase of 138.62%, which is higher than the results of the first by 7.23% (p <0.01).

Due to the impact of adverse environmental factors, unsatisfactory conditions of pig population, deterioration of food supply, abuse of antibiotics, lack of preventive measures, leads to the development of diseases among pigs, especially young, which leads to a decrease in resistance, body performance, reproduction and reduction of livestock, as well as large economic losses. The use of bacterial preparations from living microorganisms can significantly reduce or even eliminate the use of antibiotics and hormones in the cultivation of healthy animals, to obtain high-quality and safe high-grade products. The aim of the work is to study the effect of probiotic EM – 1 on the physiological state and productivity of young pigs of large white breed. The experiment was conducted on two groups (6 heads each) of animals-analogues, starting from 60 days of age, for 2 months. Animals of the control group received feed produced in the farm. Piglets of the experimental group in addition to the main diet received 5% of feed fermented with em-1. Evaluation of the physiological state and productivity of young pigs was carried out on 60, 90 and 120 days of experience according to the methods adopted in clinical practice. Hygienic, hematological, biochemical, zootechnical and statistical methods of research were used in the performance of the work. The use of probiotic EM-1 in animals of the experimental group led to an increase in hemoglobine concentration by 7.7%, an increase in the number of red blood cells by 13.7%, the total number of leukocytes by 9.52%, and glucose concentration by 11.4%. The advantage of the viability of these pigs for the content of total protein (P < 0.05), γ–globulins by 18.6%, the activity of aminotransferases (AlАT, AsAT; P < 0.05), the average daily gain increased by 12.3% at the end of the experiment. For feeding piglets feed with probiotic EM-1 increased metabolic processes, resistance and productivity of the body, which indicates a higher level of redox reactions in their body.

The results of the effect of feeding the chelated form of Zinc on the safety, productivity and slaughter parameters of broiler chickens are presented. The aim of this study was to determine the safety, productivity and slaughter parameters of broilers on the background of feeding chelated form of Zinc. Materials and methods. Experimental studies were conducted during 2020 on broiler chickens cross Cobb-500 in the vivarium of the Veterinary Faculty of Sumy National Agrarian University (Ukraine), divided into two groups on the principle of analogues (control and experimental) of 50 broilers each. The source of zinc for chickens in the control group was their sulfates. Chelated forms of Zinc were used for broiler chickens of the experimental group. All groups of broiler chickens were administered the compound with compound feed in a dose that corresponded to the daily requirement of the bird in this trace element. The duration of the experiment is 42 days. The growth and development of broilers were evaluated on the basis of determining the relevant zootechnical indicators. Live weight of birds was determined by individual weighing on scales of the VNC type with an accuracy of ±1 g at the age of 7, 14, 21, 28, 35 and 42 days. Both scientific and economic experiments also determined the preservation of livestock - daily by the number of culled and dead birds. Feed consumption was recorded daily, for each week of cultivation and for the entire period of the experiment. At the end of the experiment, the cost of feed per 1 kg of live gained weight was calculated. Results. According to the results of the conducted researches, it was established that feeding of the chelated form of Zinc probably increased both the average daily gain and the total live weight of broiler chickens at different age periods of rearing. The live weight of chickens at the beginning of the experiment was almost the same, but at 7 days of age it tended to increase in chickens of the experimental group, although a significant difference between groups in this indicator was not found. It was found that the weight of uneviscerated, semi-eviscerated and eviscerated chicken in poultry of the experimental group was greater than similar indicators in the young animals of the control group by 9.3, 9.2, and 9.8 %, and this difference was significant (p<0.01). The yield of semi-eviscerated carcasses was higher in ones of the experimental group (84.19 %), and the difference was significant (p<0.05). Conclusions. It was found that the live weight of chickens of the experimental group (consumption of feed with a chelated form of Zinc) prevailed at 7 days of age by 1.1 g; on the 14th day – on 22.1 g (p<0.01); at 21 days – 35.4 g (p<0.01); at 28 days – 94.5 g (p<0.05); at 35 days – 133.6 g (p<0.01); at 42 days – at 218.9 g (p<0.05). Preservation of young animals in the experimental group, which used chelated compounds of Zinc, was higher and amounted to 96 %, compared with the control – 92 %. By age, feed costs per unit weight gain were lower in the experiment, respectively: 0.05; 0.08; 0.12; 0.06; 0.07 and 0.05 kg, compared to the control group. Growing broiler chickens on compound feed with a chelated form of Zinc by 9.8 % (p<0.01) increases the weight of the eviscerated carcass.

The results of the influence of different amounts of triticale grain in feed on productivity, feed conversion and economic parameters of young rabbits for intensive growing technology are presented. For the feeding of experimental young, full-grain granulated feed was used in the structure of which there was a different grain content of triticale: experimental group II – 10.0%, III, IV and V experimental groups – 20.0%, 30.0% and 40.0% respectively. Experimental young rabbits of the first control group fed full-range feed, which was balanced by the main nutrients. According to the results of the research, it was found that from the 2nd week fattening in rabbits of experimental groups, which received a grain of triticale in the diet, an increase in live weight was observed in comparison with the control group. During the whole period of cultivation, the highest average daily gain of live weight was observed in rabbits of experimental group IV, which was 42.5 g, which is 10.1% higher compared to control. The advantage of rabbits II, III and V of experimental groups fed 10.0%, 20.0% and 40.0% of tritiacale derivatives was 3.0, 5.7% and 1.0%, respectively, in comparison with analogues of the control group. A similar trend was observed in terms of the absolute increase in live weight. According to the indicator of integrated assessment (RBC) of young rabbits, based on the average daily gain and width of the lumbar, the highest value was found in youngsters in the IV group (277.95) for the use of mixed fodders containing 30% of the grain yield of Triticale Harroza variety in the diet. The prospects of further research concerning the influence of various amounts of the investigated feed factor on reproductive indices of rabbits are outlined.

Abstract Study design: Retrospective cohort study.Objective: To explore the effect of a new device for kyphoplasty.Methods: 80 patients with kyphoplasty from January 2019 to December 2020 were selected and divided into experimental group (n = 40) and control group (n = 40) according to different surgical methods. The experimental group was treated with new puncture needle puncture technology, while the control group was treated with traditional puncture needle puncture technology. The operation time and intraoperative blood loss were recorded. The pain improvement was evaluated by VAS score. The operation effect was evaluated by anterior height of injured vertebral body, middle height of injured vertebral body and wedge angle of injured vertebral body. The number of fluoroscopy and the cost of operation were also evaluated.Results: Compared with the control group, the operation time and intraoperative blood loss of the experimental group were significantly less than those of the control group, and the differences were statistically significant. There was no significant difference in the ratio of anterior height of injured vertebral body between the two groups on the third day and the last follow-up. There was no significant difference in the ratio of middle height of in injured vertebral body between the two groups on the third day and the last follow-up. There was no significant difference in wedge angle of injured vertebral body between the two groups at the third day and the last follow-up. There was significant difference in the number of fluoroscopy between the two groups. There was no significant difference in the operation cost between the two groups.Conclusion: The new surgical method can shorten the operation time and reduce the radiation exposure rate of surgeons, but it has no effect on the operation effect and operation cost.

The research was conducted on two groups–analogues of young pigs of large white breed with 10 pigs each. Weaned piglets at the age of 28 days were fed with the protein–vitamin mineral supplement «Minaktyvit» – starter in the amount of 25% of grain feed (33 days), while young pigs in growing were given the protein–vitamin mineral supplement «Minaktyvit» – grower in the amount of 15% (50 days) and those in fattening the protein–vitamin mineral supplement «Minaktyvit» – finisher in the amount of 10% (62 days). The control group received protein–vitamin mineral supplement. At the end of growing with the live weight of 100 – 110 kg a control slaughter was carried out and samples of stomach, small and large intestines for laboratory tests were picked out. Studies have shown that feeding of young pigs with the protein–vitamin mineral supplement «Minaktyvit» increases the average daily gains by 95 g or 15.68%, while their level is 701 g in the experimental group of animals and 606 g in the control one. The protein–vitamin mineral supplement «Minaktyvit» incredibly affected the morphological parameters of the stomach in the experimental group of pigs. However, the thickening of the walls by 4.3%, 5% and 10.9% respectively is observed in cardiac, fundic and pyloric areas of the experimental group, compared to the control one. The thickening of the walls in stomach areas under the influence of feed factor is associated with increasing of the mucosa thickness. Mucosa increased by 0.1 mm in the cardiac area, 0.36 mm in fundic and 0.53 mm in the pyloric one. The change in the structure of the investigated jejunum is observed while consuming the protein–vitamin mineral supplement «Minaktyvit» in the diet. The wall thickness increased by 17.57% (P < 0.05), including the thickening of mucosa by 16.7% and that of serous–muscular shell by 18.8%. No significant difference in the structure of the colon in the experimental group of animals was determined.

The article highlights the problem of finding optimal variants of breeding process in a herd of pigs at purebred and crossbred selection. For this purpose, the control and two experimental groups were formed: ♀ Pietrain × ♂ Pietrain (control), ♀ (Pietrain × Large White) × ♂ Large White (first experimental group), ♀ (Pietrain × Durok) × ♂ Pitren (second experimental group). The analysis of the animals performance in these groups was carried out in 40, 30 and 35 parities, respectively. The research was conducted on the basis of PE «Maglevovany M.I.» in the Donetsk region. It has been established that the higher level of reproductive characteristics have sows of first experimental group, which have heredity of Large White breed, this breed is traditionally considered as a maternal form in cross-breeding schemes. For instance, their litter size at birth is higher than the same indicator in the control and second experimental group (plus 0,5, P<0,05, and 0,3 piglets, respectively); by the litter size at weaning at 28 days (plus 1,6, P<0,001, and 0,6 piglets); by the litter size at 2 months (plus 1,6, P<0,001, and 0,4 piglets). The highest piglet survival at the age of 2 months was in the litters, whose ancestor were boars of Pietrain breed (second experimental group) − plus 3,6 and 2,3 %, respectively, compered to purebred piglets of Pietrain breed and the first experimental group. For such complex indexes as the litter weight at weaning and litter weight at 2 months the first experimental group had an advantage of 18,1 kg (P<0,001) and 31,1 kg (P<0,001) over the control group (purebred Pietrain) and 5,4 kg and 7,6 kg − over the second experimental group. However, the average piglet weight of sows of second experimental group both at 28 days and at 2 months are equal to the average piglet weight of the same age of the first experimental group. The piglets, which are descendants of boars of meat breeds Duroc and Pietrain show a tendency to the faster growth even in an early age. The avarage live weight of pigs of the second experimental group at the age of 100 days and 7 months is higher compared to avarage live weight of pigs of the same age of the control and the first experimental groups – plus 8,5–21,7 kg (P<0,01 for the second experimental group) and 4,4–13,5 kg (P<0,001 for the second experimental group), respectively. At the age of 100 days, the maximum average daily gain was obtained in the second experimental group with an advantage of 190 g (P<0,001) compared to control group and 115 g (P<0,001) compared to the first experimental group. It is obvious that hybrids with the faster growth, which were obtained through crossbreeding ♀ (Pietrain × Duroc) × ♂ Pietrain reach a live weight of 100 kg in a shorter period: they need less time needed to reach 100 kg of live weight – 32 days less (P<0,001 ) compared to purebred animals of Pietrain breed (control group) and 18 days less (P<0,001) compared to hybrids ♀ (Pietrain × Large White) × ♂ Large White (the first control group). By such an indicator as the fat thickness the hybrids of the second experimental group dominate by purebred pigs of the same age of the control group (minus 0,2 mm), that characterize the low ability of meat breed for getting fat. The fat thickness of hybrids of the second experimental group was less by 0,9 mm (P<0,001) compared to the pigs of the first experimental group. Thus, in this herd in order to improve the reproductive qualities of sows, it is suggested to use the crossbreeding scheme ♀ (Pietrain × Large White) × ♂ Large White and to improve the fattening qualities of young animals the optimal is scheme of crossbreeding ♀ (Pietrain × Duroc) × ♂ Pietrain. Key words: pigs, Pietrain, Large White, Duroc, purebred and crossbred selection, reproductive and fattening qualities.

The purpose of the research was to elucidate the eff ect of compound feed containing an experimental concentrate intended to improve the performance of pork, when it is used at the fi nal stage of fattening pigs. The composition of the concentrate (%) was: vitamin E-0,32; vitamin D3 – 0,30; vitamin C - 0,30; vitamin B4 – 1,56; vitamin B12 – 0,004; betaine – 10,00; bentonite – 77,166; soy fl our (fi ller) – 10,00. Activity of drugs was: vitamin E - 50,0 %; D3 – 15,0 thousand. IU in 1 g; B4 -60,0 %; B12 – 1,0 %; Omec J - 2,0 %; selenium-KI – 0,2 %. Testing of the concentrate under production conditions has been carried out on two groups of pigs (n=24.) of Large White breed. The control group of animals has been received farm’s compound feed and experimental group has been received together with the compound feed experimental concentrate in the amount of 1,0 % within 10 days prior to slaughter. The average live weight of pigs when the enter to the experiment amounted to 95,7–95,8 kg when the fi nish it was 114,1–114,7 kg. Gut microbiocenosis and some biochemical parameters of pig meat have been studied. The average daily gain in live weight in pigs receiving compound feed containing concentrate increased by 2,8 %. There was an improvement in the biological value of pork protein due to the higher content of essential amino acids in it by 0,44 %. Meat samples have been obtained from animals from the experimental group exceeded the control ones by the amount of tryptophan, leucine, isoleucine in them signifi cantly. Protein-quality indicator of meat from animals of the experimental group exceeded the control samples by 3,35 units. The moisture-binding capacity of meat from animals from the experimental group was higher by 6,0 % (P < 0,05), and the color intensity by 3,0 units of extinction (P < 0,05), which is consistent with a higher hemoglobin content in the blood by 1,5 g/l. The meat of experimental animals has been characterized by the increased content of ribofl avin, biotin and folic acid. Tasting evaluation of meat and broth gave positive results.

The aim of the authors was to determine the effect of the selenium-containing preparation «E-selenium» and the homeopathic preparation «Ovariovit» on the reproductive indices of sows, as well as the tasks: to study the morpho-biochemical and immunological status of clinically healthy animals; evaluate the performance of the sows under investigation. The experiment on the basis of a large industrial pig complex in the Omsk region using healthy sows selected according to the principle of analogues allowed us to establish that the simultaneous application of the studied complex of drugs allows achieving high productive results. The positive effect of the preparations is indicated by the production parameters of the experimental group with a significant difference from the control group, consisting in a shortening of the farrowing period (P <0.01); an insignificant increase in the number of live-born piglets, the weight of the nest at birth, the average daily gain, and the average live weight of the piglets during weaning. The introduced complex «E-selenium» and «Ovariovit» with the purpose of correction of reproductive functions of sows positively influences blood indices, so on the 30th day after administration of drugs the amount of creatinine in the sows of the experimental group significantly decreased to 320.18 ± 8.69 against 401, 5 ± 13.43 in the control group (P≤0.001); a significant increase in the content of total protein in the blood of the test animals was observed by 9 % (P≤0.05). Immunological studies have confirmed the beneficial effect of selenium-containing and homeopathic preparations, namely on the 30th day after the introduction of the complex it was found that in the sows of the experimental group there was an increase in the number of leukocytes by 50 % and erythrocytes by 25.4 % (P <0.05) with values in the control group of animals. There was also a significant increase in absolute lymphocyte count in the peripheral blood. At the same time, an increase in the number of lymphoid cells was due to all populations. Especially it is necessary to allocate cytotoxic T-lymphocytes, the concentration of which relative to control increased by 2.6 times (P <0.05).
