The study of the biological role of chemical elements in farm animals is one of the issues that scientists continue to investigate. A comprehensive study of the gene pool and phenofund of breeds and species of farm animals is being carried out in Siberia. An important issue is the search for vital markers of macronutrient accumulation, including sodium in organs and tissues of animals. The article presents data on the content of sodium in the blood serum of offspring obtained from bulls-producers of the Holstein breed. The experiment was carried out at OAO Vaganovo, Kemerovo region. The sodium concentration was determined by the atomic emission method on an ICP AES IRIS spectrometer at the V. S. Sobolev Analytical Center for Collective Use of the Institute of Geology and Mineralogy SB RAS. In the area of Holstein cattle breeding, there is no excess of LOC for heavy metals in soil, water, feed, organs and tissues of animals. The influence of the genotype of the fathers of the Holstein breed on the sodium content in the blood serum of sons was established. The sodium concentration in Fabio’s offspring was 1.9 times higher (240.4 mg/ l) than in Brio’s sons (P ˂ 0.001). By the level of sodium in the serum of offspring, bulls-producers were arranged in the following order: Brio ˂ Bonaire ˂ Malstrom ˂ Fabio in a proportion of 1: 1.3: 1.5: 1.9. The phenotypic variability of this element between the offspring of different producers differed by 3 times or more. Interbreed differentiation, the influence of the genotype of producers, differences between lines and families sign the hereditary determination of resistance and susceptibility to the accumulation of macro- and microelements in organs and tissues of animals.

Intensive dairy farming in modern conditions is impossible without a solid forage base and the use of high-quality forage resources. A high level of cow productivity presupposes adequate nutrition for the animal at all physiological periods of its life. Due to the fact that cows consume relatively little feed during the first period of lactation, the primary task of livestock breeders is to provide the body of highly productive animals with the necessary amount of energy, protein and other nutrients. The article presents the data of a scientific experiment on the use of non-degradable protein in the rumen PassPro Balance in diets for fresh cows. The feed additive under study contributes to an increase in the level of dry matter consumption by animals. The average daily milk yield of the experimental group, which received the studied supplement, significantly increased by 12.0% (P <0.05) in comparison with the control group. There was also established a tendency to an increase in the fat content in the milk of cows from the experimental group. According to the biochemical analysis of the blood serum of cows, the level of albumin in all animals was within the physiological norm. The content of globulins was below the norm in animals of all groups without significantly significant differences. The activity of the AST and ALT enzymes between the groups did not differ significantly. However, it should be noted that in both groups these indicators were within the normal range. The level of alkaline phosphatase tended to increase in the experimental group by 20.8% in comparison with the control group. Feeding PassPro Supplements Balance in the diets for the experimental group made it possible to receive 2565,00 rubles of additional profit, while the level of profitability of milk production increased by 2.02% relative to control.

The aim of the work is to study the effectiveness of the use of trace elements on potatovarieties of different ripeness groups in the northern forest-steppe Ob in the Novosibirsk region.Experimental data were obtained on leached black soil of Novosibirsk region in 2017–2019. Thegenerally accepted technology of potato cultivation was used for the experiments. Since autumn,fertilizers at a dose of P90K90were applied as a general background for potatoes. Nitrogen fertilizers (60 kg / ha) were applied in the spring for pre-sowing cultivation. Foliar dressing with microelements(Cu, B, Zn) was used at the beginning of the budding phase of potato plants: copper – 20, boron –45, zinc – 50 g of active ingredient per 1 ha with a working fluid consumption of 300 l/ha. Traceelements increased the growth and development rates of potato varieties of three groups of ripeness.In varieties Liubava (early), Svitanok Kievsky (mid-early), Tuleevsky (mid-season), the use of traceelements contributed to an increase in the development indicators of the photosynthetic apparatus(maximum and average leaf area and plant productivity) by an average of 21%, especially againstthe background of boron and zinc. Foliar dressing of potatoes increased the yield parameters by anaverage of 24 % relative to the control (water). The increase in the marketability of tubers reached12 %. A greater effect was achieved against the background of boron use: a significant increase inyield, dry matter, starch, vitamin C. In variants with microelements, the susceptibility of potatoes byrhizoctonysis decreased.

The aim of the study was to determine the influence of plant species and year conditions on the biological diversity and number of insects – inhabitants of the crown layer of woody plants of the Rosaceae family in the conditions of the northern forest-steppe of the Ob region. The research was carried out in 2017–2018. During the flowering period of woody entomophilous plants, insects were collected by mowing with an entomological net in the crowns and undercrown space (25 strokes in four repetitions). In the crown of woody introduced plants Pyrus ussuriensis (Ussuri pear), Prunus maackii (Maak plum), Amelanchier alnifolia (alder irga), Spiraea betulifolia (spiraea birch leaf), Physocarpus opulifolius growing on the territory of arboretum of RAS in the northern forest-steppe of the Ob region, a total of 2597 insect specimens from 7 orders and more than 30 families were found. The largest number of insects belonged to the order Diptera (49.4 %). Representatives of the orders Thysanoptera (23.7%) and Hymenoptera (11.4%) made a significant contribution to the formation of the entomofauna. The entomofauna of different species of woody plants from the Rosaceae family differed in the taxonomic groups of insects and their numbers. A high degree of enomofauna similarity (Jaccard coefficient is 0.75) was found between Amelanchier alnifolia and Pyrus ussuriensis with similar flowering periods. A low degree of similarity was found between Amelanchier alnifolia and Spiraea betulifolia (0.32) and between Pyrus ussuriensis and Physocarpus opulifolius (0.33). The species of the plant (38.1 and 26.1%, respectively) had the greatest influence on the biological diversity and the number of entomocomplexes, which indicates the adaptation of insects to a woody plant of the Rosaceae family. The conditions of the year significantly (by 9.8%) influenced the biological diversity of insects during the flowering period.

Published: March 2021

In the non-black soil zone of Russia on sod-podzolic and floodplain soils, the adaptive properties of forage crops of the bluegrass family were assessed in terms of ecological stability and plasticity and the effect of mineral fertilizers on them according to the yield criterion. The analysis of changes in the yield of forage crops was carried out from 2009 to 2015. It was characterized by different weather conditions. As a result of the research, it was found that the environmental index varied over the years from –6.36 to 6.08. The highest adaptation coefficient was observed in Sudanese grass (1.37) and millet (1.33). The smallest yield variability was found in the cultivation of awnless brome (10.8%), millet (13.2%) and annual ryegrass (14.6%). The highest stress resistance was found in one-year ryegrass (–6.00) awnless brome (–6.20) and oats (–6.50) – the main forage crops in the study area. The minimum value of the yield range in contrasting conditions was set in millet (20.4) and awnless brome (22.0). The most stable crops in obtaining the harvest were two-source reed, annual ryegrass, Scleranthus, meadow fescue and Sudanese grass. Sudanese grass, millet and oats were the most responsive to changes in cultivation conditions. The most intense (bi = 2.40, and Sd 2 = 0.39) fodder crop in the western Briansk region is Sudan grass, while millet and oats are highly responsive in combination with low yield stability. The awnless brome reacts poorly to the improvement of external conditions, but has a fairly high yield stability. The use of mineral fertilizers increases the environmental index, adaptation, variability of the yield of forage crops, increases the gap between the maximum and minimum yield, and also enhances the stability and reduces the responsiveness of crops to environmental changes.

The research was carried out to study the influence of biologization and chemicalization factors on the phytosanitary state of barley in the chain of the six-field fodder crop rotation of the second rotation in the forest-steppe of Western Siberia. The biologization factor was considered sowing peas to barley. The chemicalization factor was considered as the introduction of mineral fertilizers according to the results of agrochemical analysis at a dose of N60P20. It was found that the highest development of root rot was found in the variant with sowing barley without fertilizers, where the disease development index reached an average of 14.4% for the plant. The lowest one is in the variant “barley + peas + fertilizers’ (4.6%). In the variants “barley + peas’ and “barley + fertilizer”, the intensity of the disease was approximately the same and within the limits of the severity threshold – from 6.6 to 6.9 %. Similar data were obtained for the prevalence of the disease. Among the analyzed organs, the primary roots had the greatest damage, which was due to significant infection with Bipolaris sorokiniana Sacc. Damage by leaf-stem infections was almost 2 times lower in the variant with the use of the legume component and the application of fertilizers (16.8%) versus the control variant (31.8%). It was found that the correlation coefficient of the root rot development index on average for a plant with productive tillering was r = –0.63, and with plant height r = –0.99. Confirmation of the harmfulness of root rot is a close negative correlation between the yield and the indicators of the development of the disease on average for the plant: r = –0.74. It was found that the most favorable phytosanitary situation developed in the variant of sowing barley with the use of fertilizers and a legume component, which is associated with the healing effect of fertilizers and legumes, which is reflected, on the one hand, in increasing the endurance of the plant itself, and on the other, in an inhibitory effect on causative agents of the disease.
Features of the epizootiological process for the main helminthiasis in cattle in the Amur region
Authors: Bondarenko G. A. , Trukhina T. I. , Solovieva I. A.
Published: March 2021

The effectiveness of the fight against helminthiases depends on the knowledge of their epizootology, age and seasonal dynamics. The Amur Region is located in a sharp continental climate zone, which affects the living conditions and health status of farm animals, including the development of various parasitic diseases that negatively affect the productivity of farm animals. The biological cycles of helminths are characterized by seasonal dynamics of development, since most of them take place with the participation of intermediate hosts that are sensitive to changes in climatic conditions (temperature, amount of precipitation), as well as to other factors. The determination of the onset of infection timing, the most unfavorable seasons and the main types of helminths are necessary for the prevention of helminthiasis in each specific region. It has been established that the basis of the population structure of helminthiases in cattle under the conditions of the Amur Region is trongylatoses, strongyloidiasis, neoascariasis and moniesiasis. The first eggs and larvae of Strongylata spp. Found in February – April. The greatest extent of invasion was observed in the winter period (February). Moniezia benedeni, as well as Neoascaris vitulorum, had the highest infection rates in the autumnwinter period. At the same time, in the annual dynamics, the first eggs of helminths in both species were found in February. Cases of detection of other helminths in cattle were first recorded mainly in the spring. Thus, the infection of cattle with helminths in the Amur Region does not depend on the grazing season, which should be taken into account when developing plans for anthelmintic measures in livestock farms.

The seasonal variability of the physicochemical parameters of milk of both ordinary goats and goats producers of a biosimilar human lactoferrin has been established. The average values of the mass fraction of fat, protein, lactose, nonfat milk solids, density index in the second and third quarters were lower than in the first and fourth quarters. At the same time, the difference between the spring-summer and autumn-winter periods in the mass fraction of fat was 25%. In the mass fraction of protein, lactose, nonfat milk solids, density it was 5–7%. Comparative analysis of milk from goats-producers of a biosimilar human lactoferrin of various lactations revealed a number of changes in the physicochemical composition of raw materials in comparison with non-transgenic animals: an increase in the mass fraction of protein by 4–6% (P˂0.05), of lactose by 2–6 (P˂0.05), nonfat milk solids by 1–6, density by 2–5% (P˂0.05), freezing temperature by 5 and a decrease in the mass fraction of fat by 5–8% (P˂0, 05). At the same time, the indicators of active and titratable acidity of milk were similar in all groups of animals. At the same time, the concentration of human lactoferrin in the milk of producers of the second and third lactation had almost identical seasonal changes in the increase and decrease in the synthesis of lactoferrin in the mammary gland during the year: in the first quarter – 2.88 and 2.97 g/l, in the second – 4.76 and 4.63, in the third – 7.44 and 7.55 and in the fourth – 7.97 and 6.72 with an average annual value of 5.84 and 5.72 g/l, respectively.

The characteristic of bulls-producers of red breeds of OAO Barnaulskoe breeding enterprise on the quality of sperm and its resistance to cryopreservation are presented. The breeding enterprise has examined samples of water, soil, feed for the content of heavy metals. In the studied samples, no excess of the LOC was found. The research results were processed on a PC using population statistics methods. Angler bulls produced the largest amount of ejaculates unsuitable for cryopreservation. It is 20.6%. According to this indicator, they surpassed the producers of red Danish and red steppe breeds by 4.1-7.8%. The animals of the latter breed showed the smallest amount (1.7%) of ejaculates rejected after defrost. In Angler bulls, this indicator was 5.95%, in red Danish bulls it was 2.95%, which is 3.52 and 1.75 times higher than in red steppe breeders (P <0.01-0.001). Significant differences were established between individual bulls of the red steppe breed in the number of ejaculates rejected before cryopreservation (2.84-22.29%) and after defrost (0-7.09%). The differences between breeds in the frequency of rejected ejaculates before freezing and after cryopreservation indicate a certain role of heredity in the resistance of animals for these indicators. Spearman’s rank correlation coefficient between these traits was 0.312. It indicates the possibility of preliminary assessment and selection of bulls according to the first indicator. But the final assessment of the bull-producers can be made by the frequency of rejected ejaculates after thawing. We propose to consider the issue of additional accounting in breeding programs for the resistance of the seed of bulls-producers to cryopreservation.

The increasing industrial activity in Indonesia, that is not equipped with appropriate waste treatment, has caused an increase of heavy metal contaminants in water bodies. Heavy metals contamination such as copper (Cu), mercury (Hg), cadmium (Cd), and lead (Pb) contamination in water bodies have endangered aquatic life and public health. For this reason, it is urgently important to lower down the concentration of heavy metal pollutants in the water bodies surrounding industrial areas. Compared to chemical remediation, bioremediation of heavy metal by using indigenous bacteria is more effective and economical, since it can be applied in situ directly and be used repeatedly. Acinetobacter sp. IrC2, used in this study, is Indonesian indigenous bacteria isolated from the industrial waste treatment facility in Rungkut, Surabaya. This study aims, firstly, to investigate the heavy metal multiresistance of Acinetobacter sp. IrC2 against mercury, cadmium, and lead. Secondly, this study intends to examine its bioaccumulation capacity for single and heavy metal alloys. The heavy metal multiresistance test was carried out by measuring the minimum heavy metal concentrations that inhibit bacterial growth (Minimum Inhibitory Concentration/MIC). The bioaccumulation capacity was measured using an atomic absorption spectrophotometer (AAS). Â It is shown that Acinetobacter sp. IrC2 has high multiresistance to mercury, cadmium, and lead with MIC values of 12 mM, 8 mM, and 18 mM, respectively. Furthermore, Â it is also resistant to Â heavy metal mixture of 4.5 mM. Â The mechanism of bacterial resistance in response to heavy metal toxicity, in general, is by accumulating heavy metals in the cells. The highest amount of accumulated heavy metals identified, from bacteria grown in the medium contains a mixture of heavy metals, were 0.023 mg, 0.084 mg, 0.684 mg, and 1.476 mg per gram of cell dry weight for copper, mercury, cadmium and lead respectively. Â In conclusion, Acinetobacter sp. IrC2 is a promising heavy metal bioremediation agent due to its heavy metal multiresistance and accumulator characteristics.Â Â Key words: Acinetobacter sp.

The genetic diversity of typical clinical isolated Plasmodium falciparum in the malaria population varies greatly, especially at the location where malaria disease were recorded at high incidence rate. MSP2 is known as glycoprotein expressed on the surface of merozoites, which is an antigenic protein and has a potential to act as vaccine candidate for malaria. The MSP2 gene has two main allelic groups called FC27 and 3D7/IC. Block 3 from MSP2 gene is the most polymorphic to describe the diversity of parasite populations. The P. falciparum parasite population is often characterized by wide genetic diversity in areas of high transmission intensity. Therefore, the study on P. falciparum diversity is useful to describe the level of malaria transmission. The study of genetic diversity focused on clinical isolated species at Wamena General Hospital was aimed to determine the presence of the MSP2 gene, variety of MSP2 gene alleleÂ  and the dominant frequency of the MSP2 gene allele. This research has been carried out from March 2018 to February 2019 using a cross sectional approach. The research sample was taken and prepared from Wamena Regional Hospital and followed by the analyzing of DNA isolation, PCR, electrophoresis of the research samples was done at the genetic science laboratory in Jakarta, Indonesia.

Amaç: Bu çalışmanın amacı, Parkinson hastalığı olan yaşlı yetişkinlerde uyku bozukluğu, anksiyete ve depresyon sıklığı yanı sıra bu şikayetler ile hastalığın evresi ve süresi arasındaki ilişkiyi incelemektir. Gereç ve Yöntem: Parkinson hastalığı tanısı ile takip edilen toplam 585 yaşlı yetişkine Epworth Uykululuk Ölçeği, Pittsburgh Uyku Kalitesi İndeksi, Uykusuzluk Şiddet İndeksi, Beck Depresyon Envanteri ve Hamilton Anksiyete Ölçeği uygulandı. Elde edilen veriler 585 sağlıklı bireyden oluşan kontrol grubunun verileri ile karşılaştırılarak yorumlanmıştır. Bulgular: Pittsburgh Uyku Kalitesi İndeksine göre hasta grubunda gündüz işlevleri ve subjektif uyku kalitesi istatistiksel olarak anlamlı düzeyde daha kötü bulunmuştur. Beck Depresyon Envanteri puanı ile Birleşik Parkinson Hastalığı Derecelendirme Ölçeği ve Hoehn Yahr Ölçeği arasında pozitif ve istatistiksel olarak anlamlı bir ilişki belirlenmiştir. Hastalığın evresi arttıkça depresyon sıklığı artarken, hastalık süresi arttıkça anksiyete sıklığı da artmaktadır. Sonuç: Özellikle Parkinson hastalığı olan, klinik olarak daha ağır olan ve daha uzun süredir tedavi gören yaşlı yetişkinlerde depresyon ve anksiyete varlığı sorgulanmalıdır. Tedaviye bağlı komplikasyonları olan hastalar uyku bozuklukları açısından değerlendirilmelidir. Parkinson hastalığının sadece motor semptomlarla ilişkili olmadığı, motor dışı semptomların etkili bir şekilde tedavi edilmesinin hastaların yaşam kalitelerini de artıracağı unutulmamalıdır.

This study aims to determine the effect of the dose of fermented rice bran using Lactobacillus sp. on growth performance and enzyme activity in tilapia. This research was conducted in Sidenreng Rappang Regency. The test animal used was tilapia larvae measuring 1.17 g. The maintenance container is a tarp pool with a size of 1 m x 1 m x 1 m filled with fresh water as much as 85 L. The study was designed using a completely randomized design consisting of four treatments and three replications, thus there were 12 experimental units. The treatment was determined based on the dose of fermented rice bran using Lactobacillus sp. which differ, namely 0, 10, 15 and 20%. The test feed was given to tilapia larvae, which were stocked with 20 fish per container for 60 days of rearing. The specific growth rate data of tilapia were analysed using analysis of variance (ANOVA) and enzyme activity was analysed descriptively based on the viability of tilapia. The results showed that tilapia fed with 20% fermented rice bran had a significant effect on the specific growth rate, protease and amylase enzyme activity. The optimal dosage of fermented rice bran using Lactobacillus sp. is 15-20%.

Red tilapia is a one of the economically important fish species. In order to increase growth and feed efficiency, feed restriction strategies can be carried out. This study aims to determine the effect of periodic (weekly) restriction of feed on compensatory growth and physiological responses of red tilapia during the enlargement phase. The activity was carried out at the Fish Breeding Research Center for 4 months. The research method used a completely randomized design (CRD) 4 treatments with 3 replications, namely control (fish were fed daily), 1 (1 fasting day a week), 2 (2 fasting days a week), and 3 (3 fasting days  a week). Fish rearing was conducted on the concrete tub measuring 2 x 1 x 0.8 m3 with a stocking density of 10 fish m-2. During the maintenance period of 120 days the fish were fed satiation twice a day. The results showed significant differences (P <0.05) in the value of weight growth, specific growth rate, daily growth and feed conversion ratio between control and other treatments, but not significantly different from treatment S1. The highest survival value was indicated by S1 treatment. The blood faal values of fish that were given feed restrictions consisting of red blood cells, white blood cells, hematocrit and hemoglobin showed that there was not significantly different than control fish (P> 0.05), which was at normal values. Restriction of feed to 1 day a week showed partial compensatory growth with better feed efficiency than fish fed daily.

Fisheries management or conservation requires information on length-weight relationship (LWR) for the fishing regulation and biomass estimation. This study aims to assess LWR estimation using two methods, regular and Bayesian hierarchical approached for big-eye Scad (Selar crumenophthalmus). Samples of big eye Scad were collected at several fish landings around Ambon Island from March to August 2020. Length-weight relationship measurement to obtain the parameters of W = a*Lb was tested using generalized linear model and t-test. The parameter b for monthly sampling was not significantly different (F = 0.77, df = 70, P = 0.89) and showed isometric growth b=3 (t = -1.13, df = 4, P = 0.32). Regular measurement resulted parameter log10(a) = -1.99 (±SD = 1.06) dan b = 3.06 (±SD = 0.084). Bayesian method produced parameter log10(a) = -2.07 (±SD = 0.2365) dan parameter b = 3.21 (±SD = 0.1497). Weight measurement from HB approach was significantly higher than the regular method (t = 1.65; df = 405; P <0.0001), and might produce over-estimated of weight from length data. Discrepancy of these methods was overcome by combining all information of LWR to obtain the best estimation on LWR parameters.

Channa striata or striped snakehead is one of species from family Channidae that widely distributed from India, Southern China to Southeast Asia including Indonesia. It is a commercially important freshwater fish because of its taste and health benefits. High demand of this species trigger many efforts to increase its production, one of them is genetic monitoring. This study used complete Cytochrome b gene sequence of mtDNA for determining genetic variation in wild population of C. striata. C. striata samples (n=31) from two different locations in Indonesia were amplified and analyzed using MEGA ver 7.0. Sequences of 1140 bp complete cyt b gene revealed the presence of 2 haplotypes with 1137 bp conserved sites and 3 bp variable sites (0,26%). Overlapping haplotype was observed in samples from Bekasi, however there were only one haplotype in samples from South Borneo. Interspecies genetic were analysed with species from Genebank and showed that C. striata from Indonesia has close genetic relationships with C. striata from Borneo-Indonesia (MN057164.1) with genetic distance 0%. This study also revealed that C. striata from Indonesia were phylogenetically distinct with C. striata from China with 9,2%K2P genetic distance. Complete cyt b gene has been proven for assessing phylogenetic relationships and population diversity of C. striata in Indonesia.

Objective: Acute mesenteric ischemia is a surgical emergency. During the course of treatment, most of the patients require nutritional treatment. However, achieving nutritional goals may not be always possible. This study aimed to investigate nutritional management of the patients who were operated on for acute mesenteric ischemia.

Materials and Methods: Patients who were diagnosed and hospitalized for acute mesenteric ischemia between 2015 and 2018 were retrospectively analyzed. Nutritional management of patients was studied in terms of hospital length of stay, mortality rate and achieving of nutritional goals.

Results: Thirty patient were included in the study and 18 patient received nutritional treatment. Median length of stay was 28.5 (range:9-220) days. Target nutrition goals were only achieved in 11 patients (61%). Overall mortality rate for nutritional treatment group was 50%. There was no significant difference between the patients whose treatment objectives were achieved or failed in terms of length of stay (p=0.375) or mortality [(p=0.630 (95% CI0,237-10,809)].

Conclusion: The management of nutritional treatment of acute mesenteric ischemia patients is challenging. Achieving the nutritional goals may not be possible in many patients.
