The work is aimed at studying the suitability of milk for cheese making and developing the technology for soft cheeses production by the thermoacid method in the conditions of personal subsidiary, individual, and collective farms. Research works have been carried out to determine the quality of milk from cows of “Studencheskiy” Scientific Production Center of the Chuvash State Agrarian University. Studies of milk at the testing laboratory center of the university were carried out according to generally accepted methods. Express research methods were used in the training and research laboratory of milk and dairy products technology. It was stated that the ratio of the mass fraction of fat and protein, the mass fraction of fat and dry skim milk residue, the mass fraction of protein and dry skim milk residue does not always meet the requirements for milk intended for cheese making. The results of milk quality research were used in developing the recipe and technology of soft cheese. As a result of multiple studies, a thermoacid method was recommended for the production of soft cheeses in the conditions of individual, collective and personal subsidiary farms.

The article considers the component composition of the specialized product for sport nutrition influences on its organoleptic parameters. The influence of sunflower flour amount introduced into the product on its organoleptic characteristics is described, the recommendations for assigning the product to the spoon or drinking type are given, depending on the content of sunflower flour in the product. A comparative analysis of the type of inoculum used on organoleptic parameters is carried out. The selection of sweetener and flavoring matter is made, the dose of their application is justified. Thе organoleptic characteristics of the product are formulated.

The article describes the results of the study of the effects of different levels of general and protein nutrition, diets with a reduced level of protein, the effect of synthetic lysine and methionine on digestive and metabolic processes, the growth intensity of young cattle and their meat productivity. According to the results of the study, the norm of fiber in the diets of gobies fed at year-round sites in winter conditions was established. The production inspection showed a high efficiency of detailed feeding standards, as well as little information about the change in the need for animals for basic nutrients depending on climatic conditions when harvesting and fattening livestock at year-round sites.

Pig breeding, as an independent livestock sector in Russia, has been developing steadily since 2008. This was facilitated by the adoption of the agricultural development program, which assumed an increase in state support for the agro-industrial complex. However, the intensification of pork production places high demands on the quality of livestock, which necessitates the use of breeds, types and lines that can withstand the loads of modern industrial technology without reducing productivity. The article presents the morphological parameters of the peripheral blood of store pigs of large white breed, obtained using a hematology analyzer. Based on the analysis of the data obtained, the authors have came to the conclusion that there is a tendency to an increase in the number of erythrocytes and hemoglobin, and a decrease in the number of leukocytes and platelets with age in the blood of fattening pigs. These changes can be associated with high growing capacity of fattening piglets and the implementation of effective preventive measures on the farm in relation to piglet anemia.

Pursuing the strategic priorities of agricultural development imposes high requirements for the professional skills of specialists. Implementing professional standards requires new methodological approaches to the formation of educational programs for training breeders-zootechnicians on the basis of the modular-competency approach which ensures training specialists for agricultural organizations who will be able to implement the federal science and technology program of developing Russian agriculture. The methods of building professional competences through the educational program development are substantiated and tested by the authors. The program provides the immediate reaction of the specialist training system to the dynamic requirements of the labor market, qualification obtaining, qualification level improvement, and career development in the directions demanded on the labor market.

The results of research on the prevention of fetal mortality in recipient cows using a combination of anesthetic and sedative agents to relieve the stress response conducting embryo transplantation are presented. It is noted that during sacral anesthesia with 2% novocaine solution and intramuscular administration of 0.5 ml/ 100 kg of xylanite solution before embryo transplantation, the physiological parameters were within the limits of the physiological norm. Temperature indicators range from 38.4±0.42 to 39.0 ±0.14 ° C, pulse and respiration an hour after administration of drugs in the first experimental group corresponded to the physiological norm (67.6±0.83 beats per minute and 26.0±2.38 respiratory movements per minute). The dose of novocaine solution is calculated according to the instructions for the use of the drug, namely, the length of the croup is measured in cm (from the mucus to the sciatic tubercles) and divided by three, the resulting number denote the amount in ml of novocaine solution require for anesthesia.The level of cortisol is lower in the group with the use of a combination of drugs by 24.6% (P<0.01) than in the control one hour after the introduction of embryos into the female genital tract.
