The bed bug Cimex lectularius L. is a common ectoparasite in the buildings of poultry farms. There are a number of chemicals for the bed bug control, although literature data reports about insecticide-resistant populations of C. lectularius. The high efficiency of pest control on large livestock or poultry farm facilities can be achieved by the competent choice of an insecticidal formulation based on the insecticide susceptibility of insects on these farms. The aim of this work was to determine the acetamiprid susceptibility of natural population of bed bugs (Cimex lectularius L.) in a poultry farm. Tests were carried out with larvae and adults bed bugs taken from the poultry facility. The susceptibility to acetamiprid was assessed by the insect dosed contact method with lethal concentrations, which were determined by the weighted probit analysis method. The median lethal concentration of acetamiprid was 0,00000648% and its median lethal dose was 1,88 μg/g of insect weight. The acetamiprid concentration that was 4 times lower than the diagnostic one led to 100% mortality of insects. The results suggest that the natural population of bed bugs from the Company “Poultry farm Pyshminskaya” are susceptible to acetamiprid.

The objects of research were the bacterial cultures of the genera Salmonella, Escherichia, Pseudomonas, Staphylococcus. The morphology of biofilms and the phases of its development were studied by the method of light and scanning electron microscopy. To study the formation of biofilms in liquid nutrient media, 24-hour microorganism cultures in S-form grown on dense or liquid nutrient media were used. The material was incubated for 24 hours at 37 °C. Then the cover glasses with biofilms formed on them were extracted with tweezers and placed in Petri dishes with filters laid on the bottom (for electron microscopy). In order to preserve the natural architectonics, were fixed by vapor of 25% glutaraldehyde during 3...5 hours. For contrasting preparations, vapor of 2...4% solution of osmic acid were used for 2...3 minutes. The laws of biofilm formation in conditionally pathogenic and pathogenic bacteria were experimentally confirmed: adhesion of single cells, association of exopolysaccharide matrix into clusters, formation of mature biofilm. SEM method shows the possibility of forming a multilayer structure of biofilm, which determines their increased resistance to antimicrobial agents (antibiotics, disinfectants).

The content of lead in the liver, kidneys and spleen of male rats of the Wistar line was studied in chronic metal intake at doses of 0,0019; 0,0023 and 0,0039 mg/ kg of body weight. Clinically healthy animals (120 heads, age of 3-4 months) were divided into 4 (four) groups of 30 heads each. Group 1 of animals received basic diet and served as control. Rats of 2, 3 and 4 groups (experiment) received 5 g of meat with different concentrations of lead daily for 180 days of study with the main diet. The content of lead in meat did not exceed the permissible level (0,5 mg/kg) and was 0,13; 0,16 and 0,27 mg/kg, respectively. Samples of organs and tissues were taken of 5 (five) animals from each group for the 30, 60, 90, 120, 150 and 180 day of intoxication. Chronic intake of lead with a diet in male rats at doses of 0,0019; 0,0023 and 0,0039 mg/kg of body weight led to increasing of the concentration of metal in the liver, kidneys and spleen. The maximum values of the index were observed in animals of 4 groups, which received lead at a dose of 0,0039 mg/kg of body weight. The comparative analysis of lead concentration in organs revealed the maximum levels of metal in the kidneys, which exceeded the standards in the by-products of slaughter animals established both in Russia and in Europe. The received results allow to speak about necessity of revision of the permissible content of lead in meat and meat products of slaughter animals specified in Russian Federation (0,5 mg/ kg) and daily admission to the human body (0,0036 mg/kg of body weight) recommended by WHO.

In recent years, a number of new disinfectants have been proposed for practical use. However, not all of them can be recommended for the food industry due to the increased requirements of sanitary and environmental safety of chemical products. Therefore, the proposed products for disinfection, for example, dairy production facilities, must be certified, accompanied by the results of toxicological studies and a recommendation about the possibility of testing a particular product in certain industries. In modern conditions, an important task set by the leadership of Russia for the scientific community of our country is import substitution in all spheres of life. The disinfecting drug Sandezffekt was developed by the Department of Veterinary- Sanitary Expertise and Biological Safety of the Moscow State University of Food Production for the food industry and veterinary medicine, as an effective analogue of vehicles produced by foreign companies. As a result of research, the effectiveness of the “Sandezeffect” preparation was established under conditions of various processing industries of the agro-industrial complex: the dairy and meat industry.

The article presents data on studies of the stability of staphylococcal biofilms. Staphylococcus grows predominantly as biofilm on virtually any type of industrial surface, causing contamination of food and water, corrosion of the metal surface and obstruction of the equipment. In particular, in the processing meat and dairy industry, biofilm formation can contribute to food spoilage and the transfer of pathogenic microorganisms, increasing the possibility of cross-contamination, which can be associated with a serious risk to consumer health. Staphylococci are often isolated from products of animal origin, but it turned out that in the state of biofilm they are more stable and viable than planktonic cells, especially after insufficiently effective disinfection.

A conceptual model of lead metabolism in the organism of farm animals with a multi-chamber stomach under intake with a ration is presented. The input parameters are determined by the daily intake of lead from the diet and the factors that modify this process. The model includes three compartments: 1) transport of lead in the gastrointestinal tract (rumen, reticulum, omasum, abomasum, small and thick intestine); 2) distribution and accumulation of lead in organs and tissues (liver, kidneys, spleen, heart, lungs, blood, mammary gland, skin, muscle and bone tissue); 3) removal of lead from the body (urine, feces, wool, milk, fetal). The paper discusses the use of the model to assess the parameters of the transition on the trophic chain «ration–animal–food», forecasting and determining the acceptable level of lead intake with feed in order to ensure the production of environmentally safe products in the conduct of animal husbandry in conditions of contamination of agricultural land.

Cow's milk is the main agricultural product and a valuable raw material for the production of dairy products. During the study the quality of milk, organoleptic, microbiological and chemical indicators are determined. The chemical composition of milk depends on many factors – the breed of cows, feeding, content, age, physiological condition of the animal, season of the year, etc. The chemical composition of raw milk is an important condition in deciding on its further processing for a certain type of dairy product. Modern national and international regulatory documents impose low requirements for the mass fraction of fat and protein in cow's milk – at least 2,8 %. Milk with a minimum content of fat and protein does not allow to obtain products with high yield. To plan the production of dairy products, it is necessary to take into account seasonal changes in the chemical composition. The Chuvash State Agricultural Academy has a small dairy farm. The academy has a training and research laboratory on the technology of milk and dairy products. In the conditions of this laboratory, milk of cows, not only of our academy, but also of personal subsidiary, farm and collective farms are examined. In this regard, it is relevant to conduct research to identify seasonal changes in chemical composition of milk. Our article presents the results of research work on determining the chemical composition of milk of cows in the dairy farm of educational scientific and practical center «Studenteskiy» of the Chuvash State Agricultural Academy in autumn. It was revealed that in September, October and November, the content of fat and protein in milk significantly increases.

To plan and improve the efficiency of disinsection measures at livestock and poultry facilities, the information on the susceptibility of houseflies to modern insecticides is needed. The goal of this study was to determine the susceptibility level to fipronil, acetamiprid, ivermectin, and chlorfenapyr in Musca domestica L. field populations inhabiting agricultural facilities. The study was conducted in one poultry and in two livestock farms. The susceptibility of M. domestica adults of the first generation to insecticides was assessed by the method of dosed contacting, after which the median lethal doses and the resistance ratio were calculated relative to the laboratory culture. According to the results, the fly population from a cattlebreeding farm, in which neonicotinoid fly baits were used for ten years, was highly resistant to acetamiprid (resistance ratio 57) and tolerant to ivermectin (resistance ratio 10). The fly population from poultry farms, in which neonicotinoids were used as baits against flies for four years, was tolerant to acetamiprid (resistance ratio 5). The fly population from a livestock farm, in which insecticides have not been used for more than five years, was susceptible to all insecticides tested. The obtained results and literature data confirmed that the rate of the development of insecticide resistance in field populations of M. domestica depends on the form and duration of the application of insecticide formulations.
