The influence of physical load to some blood components dynamics in 30-days baby rabbit’s blood during prenatal period was investigated by us. That’s why changes of normal and experimental rabbit puppies after short and long term physical load in some morphological indicators were explored through blood of 30-days rabbit puppies born by mothers suffered from hypoxia during fetal period of prenatal development. Significant changes occurred by comparison results from experiments on control animals with the results from experiment on experimental animal. Reduction and rising appeared in some indicators of blood elements after physical load in 30-days normal rabbit puppies blood and in 30-days rabbit puppies born by mothers suffered hypoxia during 10 days 20 minutes every day in fetal period of prenatal development. Therefore the level of blood indicators in normal and hypoxia condition depends on the condition of central nervous system.

The experimental studies of density distribution of the particles of a mixture of wheat, oats, rye to feed pigs by infrared heating at the time of stay and temperature at the exit of the installation. The purpose of the work is to study the quality of treatment of the product with the settings with the screw and the screw with installed round jumper on the pen of the screw. Screw installations with infrared emitters of selected wavelength give the opportunity for intense and continuous heat treatment process. The authors used the optimal parameters of the process with the screw and the screw with installed round jumper on the pen of the screw. The parameters of screw installation during the study were the following: the number of revolutions of the screw was 10 rpm, density of heat flux was 12 kW/m2, output capacity – 250 kg/h.
