Abstract

One of the ways to increase the nutritional value of feed is the use of a biologically active additive based on sprouted grain. The positive use of sprouted grain of wheat and barley has been reliably established. At the same time, the possibilities of using sprouted grain of lupine are considered much less frequently. The authors have described technique and presented the results of experimental studies on assessing the eff ect of pre-sowing UV treatment and artifi cial illumination modes during lupine germination on vitamin feed. The time of UV treatment aimed at disinfection before germination and the time of grain illumination with a phytolamp during germination were chosen as the variable factors, and the length of the shoots was chosen as the response function. The range of seed illumination was from 4 to 10 h, and the UV irradiation time was from 60 to 300 s. The germination period was 5 days. Samples exposed to natural light served as control. According to the experimental data, a regression equation was obtained that describes the eff ect of UV disinfection and illumination time during growth on the length of the shoots, and graphical dependences of the change in the response function in the intervals of variation of the infl uencing factors were constructed. Experimental data have shown that an increase in the time of UV disinfection of seeds has a positive eff ect on the length of the shoots. It was revealed that on the fi fth day of germination, the maximum length of shoots (25 mm at 11 mm in control samples) was obtained with preliminary UV disinfection of germinating seeds for 300 s and 4-hour artifi cial illumination with a phytolamp. The expediency of using this technique when germinating lupine seeds for vitamin feed for animals has been experimentally confi rmed.
