The organization of feeding animals in aviaries
Authors: Moiseeva T A 
Published: September 2020

Abstract
The article discusses the modern general rules for feeding animals kept in enclosures (in zoos). The characteristics of plant and animal feeds used in zoos are given, the need for free access of animals to feeds and water is emphasized, the controversial use of enzyme additives and antibiotics for feeding animals is indicated. The various methods for storing feed are listed. It is indicated that aviary complexes in various natural and economic regions have different species composition of fodder products, significantly different from each other; therefore, it is difficult for all of them to unify animal feeding diets. A common feature for households is that they make extensive use of local feed, because costs can be reduced only with the help of such fee. In this case, the nutritional value of feed is usually determined by the calories based on the fact that thermal energy in the animal’s body is released during the oxidation of the nutrients coming from the feed. Each group of animals has its own norms and rules of feeding and watering, the examples of dietary standards for some groups of animals are given, the importance of the method of feeding the animal is noted.

Authors: Laishevtsev A I 
Published: September 2020

AbstractRespiratory diseases of farm animals cause great economic losses to cattle-breeding, sheep-breeding and goat-breeding enterprises. On the territory of the Russian Federation one of the most wide-spread respiratory diseases among cattle, sheep and goats is Pasteurellosis, with Pasteurella multocida and Mannheimia haemolytica (earlier Pasteurella haemolytica) considered as its pathogens until not long ago. On the basis of the peculiarities and differences of the biological features of the mentioned microorganisms as well as on the basis of differences in aetiology, epizootiology, pathogenesis and clinicopathologic manifestations of the disease, infection caused by M. haemolytica was differentiated from Pasteurellosis and assigned to a new nosology – Mannheimiosis. In its turn Mannheimiosis is a Pasteurellosis-like disease, which needs some predisposing stress factors to appear. Unlike Pasteurellosis, Mannheimiosis does not appear independently, but can provoke secondary complications. Nowadays the peculiarities of Pasteurellosis are thoroughly studied, while there is not enough systematized data on Mannheimiosis. Due to all mentioned above we consider the relevance of the studies on Mannheimiosis of cattle, sheep and goats to be obvious. Presented work contents the information about microorganism M. haemolytica, the description of its cultural, morphological, biochemical and serological features, as well as factors of virulence of the pathogen, due to which pathogenesis of the infection develops. Moreover, there is information about the development of Mannheimiosis, the most typical signs of the infection, principles of laboratory diagnosis, treatment and specific prevention.

Abstract
In modern conditions of animal husbandry, when high-tech methods of breeding replace existing approaches to livestock maintenance, timely vaccination is almost the only reliable way to fight clostridiosis. Anaerobic infections are a serious problem for livestock breeding worldwide. The damage is caused by economic losses and animal deaths, as well as by the adverse conditions in the area, contaminated by spores of pathogens and losses from the introduction of quarantine measures and restrictions. Due to the wide spread of pathogens in the environment, the acute or super-acute course of the disease and the severity of damage to body tissues, treatment of animals is almost 100% ineffective compared to specific prevention. However, for the development of an effective immunobiological medication, it is necessary to justify its composition, therefore, it is important to constantly monitor the etiological structure of clostridiosis in cattle.

Published: September 2020

Abstract
The results of molecular-genetic analyses of milk sample are presented in this article. The experimental studies were carried out in the dairy cattle of livestock farms of the Vologda region suspected to the respiratory infections. Samples of milk were obtained from the cows with the following clinical signs: cough and mucosal discharges from the nasal cavity. The laboratory studies were conducted in the virology laboratory of Federal scientific center-all-Russian research Institute of experimental veterinary medicine. Polymerase chain reaction and Reverse transcription polymerase chain reaction were used for the detection of the genome of the viruses. The samples were tested for the presence of following viral infections: bovine herpesvirus, bovine viral diarrhea virus – mucosal disease, parainfluenza-3 virus and coronavirus. A comparative analysis of the nucleotide sequences of the studied virus and the reference strains of the GenBank database showed the similarity of the detected virus in cow milk of the Vologda region with the Bovine herpesvirus-5 (BoHV-5). During the differential diagnostics, the coronavirus, bovine viral diarrhea virus and parainfluenza-3 virus were excluded. Thus, as a result of the studies, Bovine herpesvirus-5 (BoHV-5) was detected for the first time in the milk of cows of livestock farms of the Vologda region.

Abstract
The article presents the results of studying the characteristics of rice grain of variety Anait. It was previously noted that in this variety in the primary seed production nurseries there is a different quality of grain on the panicle and in the plant community. This can be explained by the different quality of technological indicators of grain and milled rice. The variety of grain quality of Anait is due to the interaction of its three forms: matrix (maternal), environmental and genetic. In the primary seed production nursery (P-1) of rice variety Anait, 25 families were analyzed. A biometric analysis of plants was made and important technological indicators of the quality of grain and milled rice were determined. Variability in the grain thickness was established, expressed by the variability of the mass of 1000 grains not only between families, but also within the family, on a panicle. Rice variety Anait is unique in that it has a very large grain, but the weight of 1000 grains can vary from 33.0 to 44.4 g. The weight of 1000 grains in it depends on the thickness of the grains. Family varieties were grouped into three classes according to the grain thickness: class I - with a thickness of 2.0-2.2 mm; II class - 1.9-2.0 mm and III class - families with high mobility of the trait, i.e. showing inconsistency in thickness over 2016-2018. The variability of the main technological quality traits of grain and milled rice by classes amounted to: I class - filminess - 0.3-5.7%, grain thickness - 0.7-2.0%, weight of 1000 grains - 2.1-3.8%; II class - 0.9-8.4%, 0.3-3.2% and 0.5-3.6%, respectively; III class - 8.2-9.3%, 5.5-7.3% and 6.2-10.4%, respectively. Specific correlation relationships in each class are established, which determine their peculiarity in the subsequent seed production.

AbstractSalix contains salicylates in their leaves, bark, and buds. That is why there is a necessity in elaborating microcloning propagation technologies of same genotypes which are high productive in salicin in order to create industrial plantations. The study examined the effect of 25 different combinations of BAP and NAA concentrations on the growth and development of S. acutifolia. The best results were observed on MS supplemented with 1.0 mg/l BAP and 0.01 or 0.1 mg/l NAA, and rhizogenesis on MS medium supplemented with 0.1 and 0.2 mg/l NAA. In order to study the effect of the mineral composition of basic media on the morphogenesis of S. acutifolia in an in vitro culture, DKW, GD, MS, and WPM were tested. Kn, BAP, and 2iP were compared to study the effect of cytokinins on the morphogenetic ability of S. acutifolia explants. The influence of the mineral composition of the medium on the rhizogenesis of S. acutifolia explants in vitro was evaluated on four studied media DKW, GD, WPM, and MS. Each medium contained 3% sucrose, 0.6% agar-agar, and 0.2 mg/l NAA. As a control, MS medium supplemented with 0.2 mg/l NAA was selected.

Abstract
Control over the state of protected areas in the city is an extremely important activity, as these areas are of great recreational, environmental and educational importance, and the pressure exerted on them by residents of the city and their activities can disrupt the balance in these ecosystems. There are four main types of anthropogenic impact on natural areas: trampling and littering, contamination of water bodies and animal disturbance factors. All these problems are related to the large number of visitors to natural areas. The natural environment has a response to any human impact, which means that it is possible to identify the force of this impact and to form methods to minimize it. The condition of natural-historical park “Kuskovo” is assessed with the help of environmental control methods and devices. The flora and fauna of the territory are considered and the Red Book species are identified. Classification of forest landscapes, analysis of road and path network, recreational digression and noise impact on the investigated area were also made.

Published: September 2020

Abstract
Multipotent mesenchymal stem cells have a high therapeutic uniqueness. Their potential extends to the treatment numerous of animal diseases. This is due to their properties. They have the ability to self-renew in the culture for a long time. Upon induction to differentiation, cells are able to form cells within the same germ layer. When introduced into the body of an animal, they can exhibit an immunomodulatory effect, anti-inflammatory, anti-apoptotic and anti-fibrotic. In this regard, multipotent mesenchymal stem cells are considered as promising cellular material for the regeneration of animal tissues and organs. We conditionally divided the achievements of regenerative cell medicine described in the scientific literature using multipotent mesenchymal stem cells into groups. The division was carried out according to the nature of the pathological process (degenerative, immunological, inflammatory).

Abstract
Altai Krai is characterized by a low degree of knowledge of entomofauna of the protected areas (specially protected natural areas). The article presents, for the first time, the results of a study of necrophilous beetles on the territory of the natural monument “The confluence of the Biya and Katun rivers (Ikonnikov Island)”. The collection of the material was carried out using soil baited pitfall traps. There were discovered 64 species from 7 families of Coleoptera. The most abundant in species was Staphylinidae (43.77% of the total number of species). Families Silphidae and Histeridae have significantly less number of species (20.31% and 12.5% respectively), as well as other families (Scarabaeidae, Leiodidae, Dermestidae, Hydrophilidae), which were represented by 3-5 species each. The most abundant in the number of specimens was Silphidae (Nicrophorus vespillo, N. vespilloides, Oiceoptoma thoracicum). Common and numerous were Anoplotrupes stercorosus, Aphodius rectus (Scarabaeidae), Sciodrepoides watsoni (Leiodidae), Hister unicolor, Saprinus semistriatus (Histeridae), Creophylus maxilosus (Staphylinidae). The estimation of the species richness, degree of dominance and evenness of species in the community of necrophilous Coleoptera showed medium values of Shannon index (H=2.6), Berger-Parker index (D=0.26) and Pielou’s evenness index (E=0.44).

Abstract
Heightened interest in primocane-fruiting raspberry in the region necessitated a detailed study of this berry crop. The article introduces the research carried out in 2019 on the 0.15 ha collection site of Siberian Institute of Plant Physiology and Biochemistry of the Siberian Branch of the Russian Academy of Sciences (Irkutsk). The research objects were 9 varieties and 3 select forms of primocane-fruiting raspberry of the domestic breeding. Particular attention was paid to the biological and practical features of the research object: early maturity, cropping power, and damage caused by phytopathogenic objects. During the growing season, the varieties bearing fruit in late July – early August and those bearing fruit in the first and second ten-day intervals of September were noted. Large-fruited varieties (fruit mass more than 6 g) and large-fruited forms (fruit mass more than 7 g) were singled out. In the study season, fruiting continued until early October due to weather conditions. That allowed many plants to give maximum yield. The last harvest was on October 7, 2019. However, there were some plants that were only entering the stage of mass bearing at that moment. As a result, more early-maturing forms and varieties with the highest cropping power and resistance to fruit rot during the rainy season were registered among the range of varieties under study. Observations on the spider mite population on the plants were described. The paper describes the conditions for growing and the difficulties encountered during the planting of primocane-fruiting raspberry. The climatic conditions of the study area are described.
Supramolecular complexes of drugs for parasitic sheep invasions
Authors: Marchenko V A , Khalikov S S 
Published: September 2020

Abstract
The complex of multicellular parasites of sheep in Gorny Altai is mainly represented by intestinal and pulmonary strongilates, moniesia, dikrocelia and parasitic insects, which involves the use of complex parasiticidal agents of a wide spectrum of activity in the system to minimize the volume and frequency of use of drugs. Ivermectin (IVM) has a nematodocidal and entomocidal effect, fenbendazole (FBD) is an effective nematodocide and cestodocide, triclabendazole (TBD) is a recognized trematodocide. To obtain more effective drugs based on these substances, their mechanochemical modification using polyvinylpyrrolidone (PVP) is proposed. The aim of the work is to show the promise of using mechanochemical technology to improve the physicochemical and biological properties of drug substances and to evaluate the effectiveness of compositions of supramolecular complexes ofpolyvinylpyrrolidone with IVM, FBD and TBD in parasitic sheep infestations. Experiments on the study of the parasitocidal activity of compositions for intestinal helminthiases were carried out on a flock of spontaneously invasive sheep in the Shebalinsky district of the Altai Republic. According to the principle of analogues, 6 experimental (10 animals each) and 2 control (20 animals each) groups were formed. The preparations were given to the sheep individually in the form of an aqueous suspension orally. The study demonstrated the high efficiency of solid dispersion (SD) of the composition FBD / IVM / PVP at a dose of FBD - 3.0, IVM – 0.2 mg / kg b / w when administered orally against gastrointestinal strongylates and moniesia (95.8 and 100% ) and a bloodsucker in sheep (92.5%). SD of the composition TBD / IVM / PVP at a dose of TBD - 3.0, IVM - 0.2 showed high efficacy against gastrointestinal strongylates and dicrocelia (96.8 and 100%) and was not effective against moniesia and sheep blood suckers. The initial substances of FBD and TBD showed significantly less activity during parasitic infestations of sheep. The use of the studied SD suggests the possibility of a significant (three-fold) reduction in the dosage of FBD and TBD without loss of parasiticidal activity.

Abstract
Enzymatic processing of raw meat is a promising technique for balancing its properties. The paper presents the results of a study of the functional and technological parameters of minced meat subjected to enzymatic treatment with transglutaminase and sequential treatment with pepsin and transglutaminase. The object of the study is beef with a connective tissue content of 20%. The highest values of moisture-binding, water-holding abilities and product yield after heat treatment were established for a test sample of minced meat with sequential treatment with pepsin and 0.3% transglutaminase. According to the results of the studies, it can be concluded that low-grade beef should be treated first with a proteolytic enzyme to soften the connective tissue, and then with transglutaminase for better binding and retention of moisture.

Abstract
The aim of the study was to obtain physiological, biochemical and zootechnical data confirming the effective use of the antioxidant dihydroethoxychine to increase productivity in laying hens. The experiment was carried out on 2 groups of laying hens of the breeding herd, selected by 100 heads by random sampling. For 41 days, the chickens of the experimental group received a basic diet with the addition of dihydroethoxychine (DGE) in the amount of 100 mg/kg of feed. On the 25th day of the experiment, blood samples (n=5) were taken for biochemical studies. In the experimental group, the concentration of cholesterol in the fraction of high-density lipoproteins increased twofold (P<0.01) and in the fraction of low-density lipoproteins decreased by almost 50% (P<0.01) against the control. The concentration of MDA in the blood of chickens in the experimental group was 82.00% relative to that in the control, and in the yolk of the egg - only 37.42 %. Egg production of chickens in the experimental group was higher than in the control by 7.3% (P<0.1). Hatchability of chickens in the experimental group increased by 14.6% (P<0.01) relative to control. It was concluded that the tested water-soluble antioxidant has a positive effect on the biological functions and productive parameters of laying hens.
