Published: June 2020

When growing fish in high-tech breeding systems, it is exposed to many stress factors. To reduce stress, we used spore forms of microorganisms — Bacillus subtilis and Bacillus licheniformis, possessing probiotic properties. Two groups were formed, a control group and an experimental group that received probiotic microorganisms with feed. The aim of the study was to evaluate the effectiveness of the use of microorganisms — Bacillus subtilis and Bacillus licheniformis to reduce stress in fishes. For this indicator points were selected — stress hormone cortisol and antioxidant defense enzymes. The research results showed that stress level assessed by cortisol in fishes fed with probiotic microorganisms is 2.8 times lower than in the control group. The use of micronucleus test to assess cytogenetic damage showed that against the probiotic microbiota background, the number of cells with fragmented nuclei decreases by 5.7 times. Antioxidant defense enzyme activity when using Bacillus subtilis and Bacillus licheniformis increased, indicating activation of the defense system against oxidative stress. The obtained results demonstrated the high efficiency of the use of spore forms Bacillus subtilis and Bacillus licheniformis when growing catfish in high-tech fish farming systems. The Russian Foundation for Basic Research has supported our study with the grant No. 18-016-00127.

Published: June 2020

Currently, among chemical pollutants a significant danger to the health of animals and humans represent oxygen-containing nitrogen compounds nitrates and nitrites, which are widely used as mineral fertilizers. The article presents data on the study of chronic nitrate intoxication, reproduced in laboratory animals and its pharmacological correction with a complex of substances of phospholipid and polysaccharide nature. The introduction of sodium nitrate to non-linear rats for 30 days at a dose of 3.8 mg per animal leads to the development of intoxication in rats with dominant signs of liver damage. On this background, the use of the complex of beet fiber and rapeseed lecithin leads to a weakening of nitrate toxicosis, which is demonstrated by an increase in rats’ body weight, weakening of the clinical manifestations of intoxication, a decrease in cytolytic syndrome, intrahepatic cholestasis and impaired protein synthesis function of liver.

Published: June 2020

In domestic animals in postnatal ontogenesis, statistically significant changes in the number of α-endocrinocytes and the values of their nuclear-cytoplasmic ratio in the endocrine islets of pancreas have been revealed, which reflects the species and age-related dynamic processes of its morphofunctional development in animals. In cattle and small cattle (sheep), pigs, dogs and cats, two critical periods of postnatal development of the pancreas have been identified. The first critical period is observed from the birth to the age of three months. It is associated with an alimentary factor: the transition from a dairy diet to roughage, which leads to a decrease in the values of morphometric indicators of the pancreas and the restructuring of the functional work of the organ as a whole. The second critical period is registered in animals during puberty, that is, at 6 months of age, which is associated with the release of hormonal inducers aimed primarily at the implementation of physiological changes in the body.

Authors: Nguyen Duc Hanh , Dinh Thi Mai
Published: June 2020

Animal husbandry plays a certain role in economic growth of the agricultural sector. Compared with conventional husbandry, wildlife farming brings important, even many times greater economic benefits with certain species. At present, however, due to different objective and subjective factors, the raising of wild animals in Vietnam has not been adequately taken care of and faced several difficulties. The inadequate legal structure for wildlife farming has caused difficulties to farmers when finding breeding supplies and product output. In addition, wildlife criminals take advantage of agricultural operations to cover up their crimes, evade the detection and handle from the authorities. In order to contribute to promoting the development of agricultural economy in general, the economy of organizations and individuals participating in animal husbandry activities in particular, we aims at recognizing, examining and reviewing the existing legal system for wildlife-farming practices, crime situation and crime handling in Vietnam in recent years in this research. We will detect the difficulties, obstacles and inadequacies of the legal framework on wildlife farming, as well as the prevention and prosecution of wildlife crimes, propose strategies and guidelines for perfecting the law and appropriately implementing law provisions.

Published: June 2020

The article discusses the possibility of using natural aluminosilicates as active components of complex medicines at hepatosis in poultry. The use of bentonite from the Kantemirovsky deposit of the Voronezh region in the feed ration of broiler chickens at a dose of 2% helps to improve the general condition of the poultry, the intensity of their growth and productive indicators. In biochemical homeostasis, activation of metabolic processes such as protein, lipid, carbohydrate and mineral is noted. The inclusion of bentonite in the feeding schedule prevents the development of metabolic changes in hepatocytes and their cytolysis, which is confirmed by a decrease in the level of transaminases - AST by 22.9%, ALT by 69.8%, as well as by the accumulation of endogenous toxic substances in the body. The experiment showed that natural bentonites not only provide correction of metabolic homeostasis, but also contribute to the weakening of endotoxemia in the poultry body, showing hepatoprotective and antitoxic effects.

Published: June 2020

The article presents the study results on the fattening effectiveness of Texas Broiler quails using the formulated feed with “B.I.O. Acid Ultra” acidifier. Space and layout design of the mini-farm allowed to house 1000 head of the main flock and up to 300 young birds. The inside climate system of the mini-farm maintained the temperature in the range of 18 °C -20 °C and 75% humidity. In the study, 250 head of daily chicks were randomly selected and divided into 5 groups of 50 head each – one control group and four experimental ones. The study lasted for 8 weeks, i.e. the meat quail fattening period. The addition of the acidifier to the diet in the amount of 0.23% was found to result in 9.0% increase in the bodyweight of the 8-week old quails. The average daily weight increments also increased during the entire fattening period. The use of the acidifier reduced the feed conversion ratio by 4.1% – 6.79 versus 7.1 in the control group. However, the effect of different acidifiers on the effectiveness of quail fattening and the organoleptic and other quality indicators of the quail meat requires further comparative inquiry.

Published: June 2020

Liquid fertilizers fed into centrifugal device are spread along angle and radius of feed under action of blades. This article describes how to calculate throwing angular characteristics using Mathcad. The package consists of four programs. Program Mf is intended for calculation of probability density of supply point coordinates under assumption of bivariant normal distribution of system r, γ, which are specified in the form of vectors. The result of the calculation is displayed as matrix Mf. The program Mα calculates the throwing angle for all combinations r, γ.. To calculate the throwing angle, the method of solving differential equations of particle movement along the blade of the device with input data was used: Radius of the disk R, angular speed ω, coefficient of friction of fertilizers on the blade f. The program Ms extracts from the matrix Mf elements Corresponding to a throw angle less than a given number A. The program F (A) sums the elements of the matrix Ms. We obtained the values of the throw angle distribution function by multiplying the resulting sum by the intervals of vectors r and γ. The calculated throwing angle distribution function is approximated by the standard normal distribution function.

Published: June 2020

In the process of performing technological operations, any agricultural machinery is exposed to a large number of changing factors. The result of technological operations, in most cases, is performed by an organoleptic method, which is characterized by a significant error (up to 40%) and labor input. Given the complexity and labor input of assessing the performance quality indicators of agricultural machines, even partial automation of this process in practice gives a tangible (tens of percent) economic effect and becomes the basis for the formation of digital agriculture. We have analyzed existing methods for monitoring the quality indicators of technological operations using the example of the grain harvesting process. In particular, the possibilities of improving the methods for monitoring the performance quality indicators of a combine harvester have been considered. The correlation between the external signs of the quality violation of the technological process (losses) and adjustable parameters has been demonstrated using the example of a combine harvester thresher. A technique for adjusting the technological settings of the combine on the basis of electronic means of grain losses control, as an element of introducing the Precision Farming technologies, has been developed.

Authors: Fudin Konstantin , Konovalov Vladimir , Zaitsev Vladimir , Teryushkov Vyacheslav
Published: June 2020

The aim of the research was to establish the influence of the number and height of blades of a drum mixer on the quality of the prepared mixture of concentrated feed. The research method of the drum mixer provided for the experimental determination of the coefficient of variation (unevenness) of the mixture with a three-level combination of the blades height and their number. The absence of an extremum according to the obtained data required the use of a fourth level of the number of blades. Computer processing of the results made it possible to establish a functional dependence of the influence of design factors on the quality of the mixture. The implementation of the used research methodology for the operation of the drum mixer made it possible to establish an adequate functional dependence of the influence of the number of blades and their height on the quality of the mixture. The number of blades used practically does not affect the coefficient of variation of the content of the control component. The values change less than experimental error. However, existing trends indicate a slight (about 1%) decrease in the coefficient of variation of the mixture with an increase in the number of blades from 2 to 8 pcs. For 50 kg of feed in a drum capacity of 0.26 m3, the height of the blades is about 0.15 m. The increase or decrease in the height to 0.125 m or 0.175 m affects the quality of the mixture, increasing the coefficient of variation from 20.6% to 34-50% at the proportion of the control component of 1% and the mixing time of 200 seconds.

The restoration of plant ecosystems of brown coal dumps in the stepped areas of South Primorye occurs in two ways: 1) by reclamation; 2) by overgrowing. Only 2% of disturbed lands undergo reclamation, the rest is overgrowth. Spontaneous restoration of ground cover is the least promising, since it does not provide the formation of stable successions. The way out of this situation is the controlled contagious introduction of diasporas of species typical for a given habitat in combination with the necessary microflora.

Consider in this article, interesting in our opinion, the results of the study and the proposals of scientists in terms of determining the value of land and forest resources using the assessment options for these purposes. When conducting research on the chosen topic, we completely agreed with the opinion of many Russian scientists, said about the need to assess the value of forest lands and forest resources, which is carried out for different purposes. The most relevant for our country are: determination of fees for the use of forest resources; setting fees for obtaining the right to lease or concession of forest fund plots; determination of the effectiveness of forest land use projects and the effectiveness of forest management systems; assessment of environmental damage and the effectiveness of environmental projects, etc. In this article we have shown only part of the proposals, in our opinion, of important assessment factors and their calculations for determining the value of the forest resource in a certain territory of the country’s forest fund. They presented for your consideration a brief algorithm for the integrated assessment of forest resources and sites, compiled from research and analysis of various scientific Russian schools.

One of the main promising directions in the development of pharmacology is the development of drugs that provide targeted drug concentration and effective approaches to obtaining them using nanoscale drug delivery systems. In our opinion, the most promising is the use of biodegradable delivery systems due to their low toxicity and xenobiotic effects on the patient’s body. The need to develop regulated drug delivery systems is due to their clear advantage over analogues in standardized dosage forms. Based on modern research publications we have developed an exosomal antibacterial form of azithromycin that has pronounced selective properties for respiratory epithelial cells. The aim of the work was to study the safety parameters of the developed drug based on exosomal particles, in particular subchronic toxicity. For the study 3 experimental and 1 control groups of white rats weighing 190-220 g were formed with 10 heads each. The drug was administered intragastrically daily for 90 days in doses of 1/10; 1/20 and 1/50 of the LD50 set in the acute experiment. The study found that the use of the developed exosomal drug intragastrically once a day for 90 days does not affect the behavioral responses of animals and their external condition.

Published: June 2020

The issues related to the study of Human Resource processes optimization strategy with the use of the Lean Manufacturing system are highlighted in the paper. The HR specialist role in the recruitment system is reviewed. It is necessary to improve the current process, affecting each of its stages, to increase the efficiency of personnel selection and expand the influence on final result achievement in the food industry enterprises. The concept of HR as a business partnership (HRBP) is developed, which makes it possible to independently flag the need for personnel in accordance with company’s business plan and in some cases also to force changes needed to increase the effect of recruitment process for the company. Modified personnel selection system is introduced and the algorithm for its implementation based on Lean principles with the specified optimization effect in reducing personnel turnover rate and losses is developed. The value map, competency matrix and the list of actions needed to optimize recruitment are worked out.

The use of new non-traditional types of plant materials in the diet is one of the ways to improve the meat products’ quality. The combination of plant proteins with animals creates biologically active amino-acid complexes which increase its bioavailability for organism and biological value of the product. In this case, the use of non-traditional plant materials in the production technology of new types of sausage products to improve the quality of the end product is prospective and relevant. Research objective is development of formulations and technologies for new types of high biological value products, based on combination of meat raw materials with functional additives of plant origin. The work was performed at the Department of Food Technology FSBEI HE «Don State Agrarian University», Persianovsky, Rostov region. The objects of research were the new protein-carbohydrate complexes based on flour from germinated seeds of mung bean, control and model forcemeat based on trim beef of first grade, lean trim pork and mid fat trim pork, and end products. Introduction to the cooked sausage products formulation of mung bean germinated seeds flour has a beneficial effect on the organoleptic properties of the end product and enriches it with biologically valuable substances.
