Abstract:

Due to the increase in the range and scale of use of pesticides in agricultural practice, as well as environmental pollution from industrial and household waste, the urgency of the problem of pesticide poisoning is increasing every year. Because of the widespread use of pesticides, pests of agricultural crops resistance to them is gradually increasing, and as a result, there is a growing trend in the use of mixed pesticides. Cypermethrin causes neurotoxicity by passing through the blood-brain barrier in the central nervous system, and causes motor deficits. Also pesticide affects the peripheral nervous system. One of the most important parts in the complex treatment of cypermethrin poisoning is antidote therapy. Due to the small amount of information about the treatment of cypermethrin poisoning in an average fatal dose, the purpose of our research was to study the effect of cyanopyrethroid (β-cypermethrin) on the hematological and biochemical parameters of the animals (white rats) blood against of the therapeutic agents use. The experiments were performed in the vivarium of the laboratory of medicinal products pharmacology of The Federal Center for Toxicological, Radiation and Biological Safety. Experiments were conducted on 24 white rats of 180-210 g, β-cypermethrin (Kinmix, LLC "Green Pharmacy of Gardener") was administered intragastrically at an average fatal dose of 59.6 mg/kg, therapeutic agents was administered intramuscularly in the development of typical clinical symptoms of poisoning (depression, bronchospasm, convulsions, tremor). The animals were divided into 4 groups of 6 animals in each, the first group was a biological control (common water), the second group control (Kinmix). Animals of other groups were received β-cypermethrin and medicinal preparations in the development of clinical symptoms of poisoning. The third group was received treatment consisting of dipyroxime (28.0 mg / kg), sodium bromide (28.0 mg/kg), pyridoxine (0.4 ml) and diosmectite (12.0 mg/kg), the fourth group phenazepam (5 mg/kg) and diosmectite (12.0 mg/kg). According to the results of studies, in animals poisoned with β-cypermethrin in an average fatal dose (59.6 mg/kg) the best effect was obtained in the group with the use of dipyroxime, sodium bromide, pyridoxine and diosmectite. As a result, the survival rate of animals was 83.5%, which is confirmed by hematological and biochemical studies.

Abstract:

Organophosphate pesticides occupy one of the leading places among the preparations used in agriculture. Their high efficiency in the protection of animals and plants has been proved. Organophosphate pesticides are successfully used in the agricultural industry as insecticides and acaricides. At the same time, despite the proven feasibility of use in the national economy, pesticides are characterized by a high danger to humans and animals. The current situation with the treatment of poisoning with organophosphate pesticides necessitates the development of new domestic effective antidotes, one of the main components of this ones are holinolytics. The article presents the results of experimental studies aimed at studying the parameters of acute and chronic toxicity of the new domestic antidote RR-2 synthesized in the FCTRBS. Experiments were carried out on pond fish and guppies. For this purpose, the animals were kept in antidote solutions. Survival, behavior, and weight of specimens were evaluated. According to the results of experiments, the acute toxicity of cholinolytic for ponds is 150.0013.8 mg/dm3, for fish 125.9912.82 mg/dm3.

Abstract:

The main requirements for feeds are their safety and nutrition, ensuring the physiological needs of animals. Safety indicators include toxicity, the content of toxic elements, mycotoxins, pesticides, nitrates and nitrites, conditionally pathogenic and pathogenic microflora. The purpose of the research is to assess the general (integral) toxicity of feed received from the Republic of Tatarstan (Zelenodolsky, Nurlatsky, Buinsky, Baltasinsky, Arsky, Laishevsky districts, Naberezhnye Chelny). The experiments were carried out in the laboratory of mycotoxins FTSTRB-VNIVI. In the studied feeds, the general toxicity was determined according to GOST 31674-2012 for 3 types of test objects (stylonichia, white mice, rabbits). 89.8% of feed samples by bioassay on protozoa showed no toxicity; 4.1% were toxic. In all cases, the bioassay on white mice was negative (no death of the animals and no visible changes in the internal organs during the autopsy of the animals killed were observed). In two cases, dermatonecrotic effect was revealed when applying extracts of the studied feed to the skin of rabbits. It is worth considering the fact that the official interpretation of the research results requires adjustment depending on the type of animals. In the case of toxicity on protozoa and the absence of toxicity on white mice and rabbits, the food is officially considered non-toxic, but given that the cicatricial microflora, including ciliates, plays a special role in digestion in ruminants, it must be considered toxic. Most of the studied samples of feed from livestock farms of the Republic of Tatarstan by the bioassay method were recognized as benign and recommended for use without restriction. For livestock farms where toxic feed has been discovered, recommendations have been issued for their further use.

Abstract:

Determining the level of natural resistance is essential for assessing the state of the human body and animals, the severity of the development of negative processes and the forecast of consequences when exposed to man-made environmental factors. The available methods for determining humoral factors of natural resistance are labor-intensive and require large amounts of test serum or plasma, reagents, and test culture. This makes it difficult to use them for a large number of samples in model Toxicological and radiobiological studies, as well as for mass inspection of farm animals in technogenically polluted territories. Automation of the detection process with the help of technical solutions used for enzyme immunoassay can help solve this problem successfully. Studies have shown that the values of lysozyme, β-lytic and bactericidal activity of the blood of irradiated rats, determined using standard methods, and ELISA do not differ significantly. The dynamics of the studied humoral factors of natural resistance in animals after radiation exposure in the dose range from 3 to 12 Gy depended on the radiation dose, and not on the method of determination. It was demonstrated that the use of ELISA to determine the level of natural resistance of animals allows to: decrease the volume of the studied serum or blood plasma test and culture; to increase the number of simultaneously analyzed samples, to measure parallel samples to maximize the accuracy of the studied parameters.

Abstract:

Food products, ready-to-eat and semi-finished products of animal origin, due to the peculiarities of manufacture and storage, can be a source of intestinal infections and such dangerous diseases as listeriosis and erisipiloid (erysipelas). The most at risk are consumers with immunodeficiency during the rehabilitation period, after the use of immunosuppressants, cytotoxic drugs and ionizing radiation during the treatment of cancer. If infection with banal intestinal infections and listeriosis occurs alimentary, then an erisipeloid can develop after contact with the causative agent of the disease during cutting and preparation of products from pork obtained from animal carriers of bacteria. A study of the possibility of using radiation technologies to ensure microbiological safety of problematic food products showed that irradiation of minced meat in a vacuum package at a dose of 1.5 kGy leads to complete inactivation of the listeriosis pathogen. A positive effect was observed during the radiation processing of minced meat (dose of 0.5 kGy) in a modified gas environment (75% O2, 25% CO2). It was shown that the magnitude of the effective dose depends on the concentration of Listeria monocytogenes in production. The fact that the pathogen of erisipeloid does not form spores and capsules (radioresistant forms) suggests that the inactivating dose will not exceed 3 kGy. According to numerous data, radiation treatment in this dose range does not reduce the quality of food products. Thus, radiation technologies can be considered as the best way to provide people with immunodeficiencies with safe and quality food products.

Abstract:

The leading role in elimination of infectious agents from the body, such as anthrax, belongs to cells with phagocytic properties, immunoglobulins and proteins of the complement system. The paper presents the materials of studying the dynamics of the functional activity of phagocytes of animals vaccinated against anthrax. Functional activity of phagocytic cells was evaluated by the phagocytic activity of leukocytes. Phagocytic activity (FA) was determined in calculating the relationship of phagocytic neutrophils to the total number identified and their absorption capacity for the phagocytic index (PHI) the number of microbial cells in terms of one active neutrophil. During the study observed the increase in the values of phagocytic activity and phagocytic index, which reached their maximum values at day 14 after immunization, indicating activation of factors of natural resistance of the organism. High values of the studied parameters was observed up to 150 days after vaccination. In the further periods of the study, indicators fell to levels identical to the control group. The decrease in the examined values to the level of the control group determines the low efficiency of presentation of antigens to cells of the adaptive immune system, and as a result, the actual phagocytosis final stage of the immune response. Reducing the number of active phagocytes to 120 days after vaccination may be associated with complete elimination of the introduced vaccine strain from the body by this time.

Abstract: Results of research of an alternative way of release of antigen of a virus of the rage based on a method of three-phase extraction of initial suspension and scoring on a dispergator and also estimates of immunochemical properties of the received product are presented. Initial virussoderzhashchy material of organ and fabric origin was subjected to extraction by serial processing by saturated solution of sulfate of ammonium (NSA) and a butanol. For fuller disintegration the extracted suspension was subjected to scoring on an ultrasonic dispergator of UZDN - 2T then anti-gene samples processed 96% ethanol in different proportions. Anti-gene properties of the received fractions estimated by methods of an analytical disk-electrophoresis, a western - a blotting and "sandwich" - IFA. It is shown that application of ultrasonic processing of the extracted suspension of virussoderzhashchy material and further processing of 96% ethanol in the ratio 1:1 allows to get rid of ballast substances and subvirus components more effectively. The received anti-gene product is monomeric, supports one prevailing proteinaceous fraction weighing 67.2 kd that corresponds to G-protein of a virus of rage and also has a caption in "sandwich" - IFA 1:40960. These characteristics confirm high diagnostic efficiency of this antigen and its suitability for a complete set of express test systems on the basis of IFA. The described way of release of antigen by means of chemicals and ultrasonic processing can be considered as an available and economic alternative to the considered earlier zone ultracentrifugation in density gradients.

Abstract:

The experiment provides information on a comparative study of the biological characteristics and productive traits in bull-calves of various genotypes under the year-round feedlot conditions, OOO, conducted a scientific and economic experiment. The scientific and economic experiment was conducted on three groups (30 animals each) of bull-calves of Kazakh white-headed (I group), Simmental (II group) and Kalmyk (III group) breeds in Yubileynoye LLC, Adamovsky District, Orenburg Region to achieve appointed goals. The test animals were kept on a feedlot combined with a light type building for resting and feeding individuals in bad weather. All technological processes associated with keeping and feeding animals were mechanized. During the experiment, bulls of all experimental groups received the same rations, consisting of mixed grass hay, haylage, corn silage, concentrates in accordance with detailed feeding norms, taking into account the receipt of 800 - 900 g of daily gain in body weight. The diets were balanced by basic nutrients and adjusted according to live weight and growth rate of individuals of various genotypes. During the experiment, the average monthly outdoor temperature at the feedlot in autumn was from + 10.0 to -5.5 C, in winter from -10.8 to -15.7 C, in spring from -8.8 to + 9,9  C. Relative humidity ranged from 55 to 86%, wind speed from 0.3 to 9.7 m / s. As a result of the study, it was found that Simmental bull-calves had the highest live weight and absolute growth rate. They were ahead of their beef cattle peers in the first indicator by 12.5 (3.06%) and 28.0 kg (7.13%), in the second - by 6,4 (3.6%) and 13.3 kg (7.9%). In general, the average daily gain over the period of the experiment of bull-calves from groups I, II, and III was 836; 866 and 803 g with maximum performance in individuals of the Simmental breed. However, the bull-calves of the Kazakh white-headed and Kalmyk breeds were more resistant to the influence of environmental factors. They exceeded the comparable peers of the Simmental breed in terms of bactericidal activity of blood serum by 5.2 and 4.0%, serum lysozyme activity - by 1.4 and 1.6 times in unfavorable months by climatic conditions. The greatest activity of β-lysines was observed in individuals of all groups in the winter (15.2 - 17.6%), lower - in fall (14.9 - 15.7%).

Abstract:

In two scientific and economic experiments conducted by the group-analog method in the conditions of a poultry farm in the Chuvash Republic, the effect of feeding preparations of water-soluble vitamins C, Bc and B13 to laying hens of the cross "Loman-brown" on their egg production and egg quality was studied. In the first experiment, the birds of the experimental groups were given 50 mg of ascorbic acid, 1 mg of folic acid, and 5 mg of potassium orotate for 180-230 days as part of 1 kg of compound feed PK-1-3. In the second experiment, we studied the effectiveness of introducing potassium orotate into compound feeds for laying hens at doses of 5.0, 7.5 and 10.0 mg per 1 kg of feed. Such feeding contributed to an increase in egg-laying hens of the experimental groups in comparison with the control groups by only 3.0 5.8 %, with a significant improvement in the vitamin value of food eggs. In the first experiment, there was an increased content of thiamine, Riboflavin, ascorbic acid and retinol in the yolk of eggs by 20% compared to the control group. When studying the effectiveness of introducing into feed of vitamin B13, it is established that at the dose of 5 7.5 mg/kg was an increase in egg yolk of laying hens of the experimental groups compared with the control carotenoids 4.5 to 7.1 %, vitamin A 52 59 %, thiamin 14.3 28.6 per cent. In 1 kg of feed, the content of ascorbic acid should be at least 75 mg, folic acid-102 mg, potassium orotate-7.5 mg.
