Biological Preservative

The effect of a new biological preservative representing a mix of lyophilized Lactobacillus plantarum VKPM V-4173, Lactococcus lactis subsp. lactis VKPM V-2092 and Propionibacterium acidipropionici VKPMV-5723 strains (40 : 40 : 20) on the quality of haylage prepared from a mix of vetch, oats, and pea has been studied. The total bacteria content in the preservative was 1·1011 CFU/g. Five different variants of conservation of alfalfa haylage prepared at the budding stage were evaluated under laboratory conditions. The variants included a self-conserved control and the preservative at two different dosages (3 and 6 g/ton) with and without the addition of cellulolytic enzymes. The best results were observed in the case of both the enzyme-free and the enzyme-containing preservative at the dosage equal to 6 g/ton. These variants provided the maximum protein content in the haylage (94.3% and 94.5% of the initial content, respectively) and a high content of lactic acid (62.9% and 65.4% of the total acid content, respectively) and also good organoleptic characteristics. The determined optimum biopreservative dosage was tested under industrial conditions using 750 tons of vetch-oats-pea haylage. The use of the biopreservative provided a high-quality haylage of high nutritive value. Industrial evaluation of the effect on the productivity of milk cattle (n = 15) of the addition of the biopreservative to the haylage showed that the maximum average daily yield of milk with basic fat content (3.4%) was obtained from cows of the experimental group whose ration included haylage prepared with the use of the studied preservative. This yield came to32.7 kg , which exceeded the yield for the control group (fed on self-conserved haylage) by 7.0%. Three months feeding of cows with the haylage prepared with the use of the new preservative brought a significant saving of money (4,862 rubles per a head at the prices of 2015–2016).

Promising in feed production is the preparation of haylage with subsequent storage of herbage together with preservatives. The modern market off ers various chemical preservatives in the form of organic acids: propionic, formic, benzoic and their salts. Some disadvantages of preservatives of this group (volatility, toxicity, venom, ability to cause respiratory burns, corrosion, etc.) require to organize a search for new ones based on bacteria and enzymes. The purpose of the work was to increase the level of milk productivity of cows and quality of milk by using the preservatives Biosib and Silostan in the preparation of haylage. Scientifi c and economic experiment has been carried out in LLC “Agrofi rma Bairamgul” in the Uchalinsky area in the Republic of Bashkortostan. For the research, 36 Holstein cows have been selected, from which 3 groups of animals have been formed based on the principle of analogues per 12 heads in each. The input in the ration of lactating cows of grain and legume haylage prepared using the technology with the use of preservatives Biosib and Silostan contributes to the increase in milk productivity. The best eff ect has been demonstrated when using the drug Silostan (the 2nd experimental group), which can be explained by the diverse biological composition of microbes, as well as amino acid complexes, enzymes, vitamins and trace elements. The increase in milk productivity of cows of the 1st and 2nd experimental groups allows to reduce the prime cost of production, respectively according to groups, by 38,7 rubles or 3,31 % and 51,1 rubles or 4,43 %; to increase revenue from the sale of milk by 3186,5 rubles or 4,32 % and 3664,0 rubles or 7,24 %; net profi t by 1791,9 rubles or 17,97 % and 2570,6 rubles or 25,78 % and the level of profi tability by 4,14 and 5,52 % compared to the control group.

The association between science and production is gradually developing due to the arrival of new information and discoveries about the composition of feed and the transformation of nutrients in the body of cows. One of the most important links in the formation of animal productivity during lactation is the use of new feed products and feed additives in feeding. The results of scientific and economic experiment on the use of protein concentrate “Agro-Matic” in feeding of highly productive lactating cows of Ayrshire breed are contained the article. The inclusion of protein concentrate “AgroMatic” in the daily rations of lactating cows in the amount of 1,0 and 1,5 kg/head/day increases the level of indigestible protein by 6,1 and 8,9 %, respectively. The use of protein concentrate in the amount of 1,5 kg in cows feeding helps to increase the digestibility of nutrients in rations the quality of milk and the productivity of cows. When feeding protein concentrate in the amount of 1,5 kg the milk productivity of cows during the period of increasing the milk yield was 4297,5 kg of milk, the yield of essential and dispensable amino acids with milk was significantly higher. The yield of milk protein in cows that received protein concentrate in the ration in the amount of 1,0 kg was 137,7 kg, and when using 1,5 kg – 141,4 kg, which was signifi cantly higher than in the control group by 10,2 and 13,6 kg, respectively. The use of protein concentrate “Agro-Matic” in the ration had a benefi cial eff ect on the digestibility of protein. The digestibility of raw protein of the feed mixture with the inclusion of 1,5 kg of protein concentrate was 71,1 % compared to 68,0 % in the basic ration, which are used at the Maysky complex in the “Plemzavod Maysky”

Relevance. Fermentation of cabbage is a common way of processing, which allows to preserve and strengthen its useful qualities. To date, breeders have proposed a significant number of varieties and hybrids of cabbage, each of which has its own individual biochemical characteristics. Traditional sauerkraut is carried out after harvest. Long storage can affect the change in the content of organic acids and sugars in cabbage.Methods. The aim of the work was to study the parameters of the fermentation process of eight varieties and hybrids of cabbage by selection in the Federal State Budgetary Scientific Institution Federal Scientific Vegetable Center by the intensity of sugar reduction, accumulation of organic acids, organoleptic parameters and activity of lactic acid microorganisms. Fermentation was carried out after a 5-month period of storage of heads.Results. The results showed that the storage period did not affect the fermentation result of most of the studied varieties and hybrids of cabbage. There are varietal differences in the initial content of mono-and disaccharides, organic acids, which affected the fermentation process. The increased content of malic acid in the variety population Podarok, F1 Severyanka contributed to the slowdown of the first stage of fermentation. Varietal features of the Parus population contributed to the slowdown of the first and second stages of fermentation, which was manifested in a decrease in the rate of destruction of sugars. Variety Zymovka 1474 in the process of processing by fermentation accumulates a significant amount of succinic acid, which can characterize its special difference among the studied varieties and hybrids. The best organoleptic characteristics were distinguished by hybrids of fermented cabbage F1 Likova, F1 Natali, F1 Mechta and F1 Snezhinka. The results of the study suggest that the processing of cabbage by fermentation should take into account its individual varietal biochemical features. This will not only preserve the valuable nutritional properties of the cabbage itself, but also strengthen them by optimizing the natural process of lactic acid fermentation. The result will be the best organoleptic effect achieved by an optimal combination of lactic and citric acids and mono-sugars.

Because of economical reasons the substitution of maize by feed corn as wheat (Sulamit) and triticale (Kitaro) was revolved in concentrate part of dairy cow feeding rations. The design of mentioned replacement in feeding rations was carried out according to results of previous research (Pozdíšek and Vaculová, 2008) for nutrition experiment. The aim of this paper was to evaluate the possible effects of corn replacement in cow feeding rations on milk composition and properties. The expressively different variants of corn were selected for experiment in comparison to maize (reference). Dairy cows were fed by total mixed ration on the basis of maize and clover silage and hay. Otherwise the identical day feeding rations among cow groups differed only in concentrate portions ((K, control group) maize 1.5 kg, wheat (P1) 2.0 kg and triticale (P2) 2.0 kg (experimental groups)). Group feeding rations 1 (K), 2 (P1) and 3 (P2) had: NEL/kg dry (DM) matter (6.524, 6.512 and 6.491); NL % in DM (17.9, 18.2 and 17.9); fibre % in DM (15.96, 15.74 and 15.72); PDIN/PDIE (1.189, 1.189 and 1.191). The experiment took six weeks, there were included 8, 9 and 9 cows (n = 26) of Czech Fleckvieh breed. Feed groups were well balanced in terms of milk yield, days in milk and number of lactation. The tie stable and pipeline milking equipment were used in experiment. Animals were milked twice a day and sampled at morning milking in intervals about seven days approximately. Cows were relatively healthy in terms of occurrence of milk secretion disorders. Within groups the individual milk samples (in total 182 in experiment) were aggregated into bulk samples (n = 21 = 3 groups × 7 sampling periods), which were analysed on 45 milk indicators, 18 of them were evaluated in this paper. The differences in milk yield were significantly advantageous for K group (15.32 > 14.07 (wheat) or 13.86 kg (triticale) at morning milking), while fat (3.27 < 3.47 or 3.44 %) was lower (P < 0.05). Lactose was not influenced. More important differences were in total dry matter, 12.09 (K) < 12.23 (P1) or 12.40 % (P2). While for wheat was not for triticale was similar effect observed in crude protein (CP) of milk (3.08 (K) or 3.05 (P1) < 3.23 % (P2)). Similar trend was also confirmed in casein (CAS; 2.43 or 2.44 < 2.55 %; from P < 0.05 to P < 0.001 for CP and CAS). There were insignificant differences between groups for casein number, pH acidity, electrical conductivity, Mg and Cu (P > 0.05). Milk specific weight was lowest in P1 (P < 0.01), but this indicator is practically less important. More expressive differences were in somatic cell count (SCC) in geometric mean 249 (P2) > 76 (K) or 72 103/ml (P1). Because of quite typical high SCC variability in tri­ti­ca­le P2 group (in opposite to this low variability in K and P1 groups) it could be caused by chance in animal selection for groups and all values met the standard demand for extra quality of milk. Therefore, it is not necessary to over estimate this result. Milk urea as metabolical indicator was higher in wheat group, significantly (P < 0.05) versus triticale group (23.39 (P1) > 20.80 (K) and 20.50 mg / 100ml (P2), but all values lay in respected physiological range (from 20 to 30 mg / 100ml). In the Ca case it was significantly higher (P < 0.05 versus wheat) in triticale milk group by 5.7 and 4.0 % (1306 (P2) > 1231 (K) or 1253 (P1) mg / kg). This increase could be interested in terms of milk nutritive value, but not for routine milk payment. The levels of P and Fe in milk were higher in K versus experimental groups (P < 0.05). It is less interesting in terms of economy or nutrition. In general milk was a little different according to differences in corn portions of cow feeding rations and corn variant replacement. In terms of experiment the concrete corn replacement in concentrate portion of feeding ration could not have an essential impact on milk quality and it si possible to agree with such conception. However, the milk quality and yield were not overcome by replacement of maize by wheat (Sulamit) or triticale (Kitaro). At triticale the lower milk yield was compensated by higher levels of DM, fat, CP, CAS, Ca and also SCC as compared to maize and wheat. The used corn replacement variants were not expressively worse than maize.

The realization of the genetic potential of farm animals is first of all determined by the complete feeding, which is determined by its balance in accordance with the needs of animals with a certain physiological state and level of productivity. The study of enzyme compositions in the feeding of mammalian farm animals that promote better digestion of incoming nutrients is an urgent issue. Feed enzymes not only increase the digestibility of individual feed components, but also allow you to increase the rate of input of inexpensive raw materials “rich” in anti-nutritional factors without compromising the health and productivity of the animal. The purpose of the research was to study the use of enzyme compositions in the feeding of cattle and pigs. The results of the study of enzyme compositions in the rations of lactating cows during the period of increasing the milk yield and pigs during the period of rearing and fattening have been presented in the article. The input of enzyme additives with a cellulolytic effect in the rations of cows had the positive effect on the digestibility of nutrients in the feeding ration, milk productivity, and the composition of milk. During the first 100 days of lactation milk with natural fat content was produced from cows of the 1st experimental group by 5,5 % more and from cows of the 2nd experimental group by 13,8 % more than from animals of the control group. In terms of 4 % milk the animals of the 1st experimental group exceeded the control analogues by 7,32 % and in the 2nd group by 18,1 %. The input of 1 kg/t of feed in the diet of the multienzyme composition “Kemzaym W” animals allowed us to get 81,7 kg of additional gain, more profi t compared to the 1st experimental group, where the additional gain was 24,7 kg. The use of the multienzyme composition “Kemzaym W” in the amount of 1 kg/t in the diets of young pigs had the positive effect on the digestibility of raw nutrients, on the increase in live weight and average daily gains, on the yield of meat and the quality of carcasses.

When interacting on a learning task, which is typical of several academic situations, individuals may experience two different motives: Understanding the problem, or showing their competences. When a conflict (confrontation of divergent propositions) emerges from this interaction, it can be solved either in an epistemic way (focused on the task) or in a relational way (focused on the social comparison of competences). The latter is believed to be detrimental for learning. Moreover, research on cooperative learning shows that when they share identical information, partners are led to compare to each other, and are less encouraged to cooperate than when they share complementary information. An epistemic vs. relational conflict vs. no conflict was provoked in dyads composed by a participant and a confederate, working either on identical or on complementary information (N = 122). Results showed that, if relational and epistemic conflicts both entailed more perceived interactions and divergence than the control group, only relational conflict entailed more perceived comparison activities and a less positive relationship than the control group. Epistemic conflict resulted in a more positive perceived relationship than the control group. As far as performance is concerned, relational conflict led to a worse learning than epistemic conflict, and - after a delay - than the control group. An interaction between the two variables on delayed performance showed that epistemic and relational conflicts were different only when working with complementary information. This study shows the importance of the quality of relationship when sharing information during cooperative learning, a crucial factor to be taken into account when planning educational settings at the university.

Introduction.Coccygodynia is a multidisciplinary disease which is diffi cult to treat. It seriously limits the ability to work and signifi cantly affects the quality of life of patients. The study of somatic dysfunctions in patients with coccygodynia and the analysis of the results of osteopathic treatment of such patients makes it possible to justify the necessity of osteopathic correction of coccygodynia.Goal of the study— to determine the structure of the leading somatic dysfunctions in patients with coccygodynia and to study the effectiveness of osteopathic treatment of this pathology.Materials and methods.The study involved 44 patients from 25 to 65 years old, randomly divided into two groups. The main group of 24 people (20 women and 4 men) received osteopathic treatment, in accordance with the identifi ed leading somatic dysfunctions. Patients of the control group (16 women and 4 men) were treated locally with soft manual techniques (the treatment area was limited by the pelvic region). In order to assess the results of the treatment, we examined the intensity of the pain syndrome and the psycho-emotional state of patients. The severity of the pain syndrome was assessed in accordance with the visual analogue scale (VAS). The psycho-emotional state (with physical and mental components) was assessed with the help of the SF-36 quality of life questionnaire.Results.Somatic dysfunctions typical for patients with coccygodynia have been identifi ed. Osteopathic treatment has proven to be more effective in comparison with local manual therapy of coccygodynia both in early periods and in 3 months after the end of the treatment course.Conclusion.Osteopathic treatment of post-traumatic coccygodynia is effective, and can be recommended for treatment of such patients.

In order to increase the pregnancy rate in the assisted reproductive technology, the selection of one embryo with the highest implantation potential it is very important. Time-lapse microscopy (TLM) is a tool for selecting quality embryos for transfer. This study aimed to assess the benefits of single-embryo transfer of autologous oocytes performed on day 5 of embryo incubation in a TLM-equipped system in IVF and ICSI programs. Single-embryo transfer following incubation in a TLM-equipped incubator was performed in 282 patients, who formed the main group; the control group consisted of 461 patients undergoing single-embryo transfer following a traditional culture and embryo selection procedure. We assessed the quality of transferred embryos, the rates of clinical pregnancy and delivery. The groups did not differ in the ratio of IVF and ICSI cycles, average age, and infertility factor. The proportion of excellent quality embryos for transfer was 77.0% in the main group and 65.1% in the control group (p = 0.001). In the subgroup with receiving eight and less oocytes we noted the tendency of receiving more quality embryos in the main group (р = 0.052). In the subgroup of nine and more oocytes the quality of the transferred embryos did not differ between two groups. The clinical pregnancy rate was 60.2% in the main group and 52.9% in the control group (p = 0.057). The delivery rate was 45.0% in the main group and 39.9% in the control group (p > 0.050).

Many mothers who give birth to Sectio Caesarea (SC) do not Initiate Early Breastfeeding (IMD), which fails exclusive breastfeeding. This study aimed to determine the effect of IMD management in postpartum SC mothers on nutritional status, speed of milk production, and quality of breast milk protein. Method: quantitative research with quasi approach experiment. The research design used was a pre-post-test control non-equivalent control group. A sampling of this study used the Consecutive method sampling with a sample of 20 mothers who gave birth by cesarean section (SC). Hypothesis testing uses the independent t-test and the Mann-Whitney test. The study results showed an influence on the management of IMD in postpartum SC mothers on the speed of ASI production (p-value=0.004) and nutritional status (p-value=0.028). There was no effect of IMD management on postpartum SC mothers on the quality of breast milk protein (p-value = 0.543). This study recommends that the hospital implement an IMD promotion program before the abdominal wall is closed as a form of intervention to increase milk production and maternal nutritional status
