The methods of mathematical planning of the experiment determined that the optimal dosages in the formulation of bread powder from microalgae Dunaliella Salina are 5.0-10.0 % by weight of flour in the dough. As a result of applying the recipe of promising new plant additives the organoleptic quality (taste, odor, status crumb) and physical-chemical parameters of the finished products (specific volume and porosity of bread crumb) improves. Due to the increased content of protein substances, including essential amino acids, dietary fibers, vitamins, minerals the bread has increased nutritional and biological value and can be considered as a product of therapeutic and preventive purposes. The range of functional bakery products is also expanding.

The article deals with the preparation for the experiment on long-term monitoring of the temperature of eggs and brooder-hens, the heart rate and the motor activity of the embryos and the motor activity and the behavior of brooder-hens during natural chicken brooding in laboratory conditions. The issues of laboratory premises selection and their internal layout are discussed. We suggest protecting the hardware from dust and excessive humidity by installing it in an isolated chamber in the immediate proximity to the cages with birds. The factors influencing the results of the experiments that involve living animals are analyzed. Some ready-made solutions are suggested to arrange the power supply of the laboratory. We also describe the appropriate components of the hardware set for the monitoring of the controlled parameters.

The article describes the milk productivity of the main genealogical lines of cows of the Voronezh type of red-mottled dairy breed of cattle bred in the Voronezh region, taking into account the linear affiliation. A sample of cows produced breeding plants area of PZ “Druzhba” and PZ “Bolshevik”. Analyzing the results of milk production and longevity of livestock, paid attention to the number of cows on lactations; percentage of disposal to 1 lactation; milk yield for 305 days of lactation, kg; milk yield of average productivity for 305 days of lactation, kg; average age of cows in lactations; lifetime productivity of cows, kg.
