Studying the effectiveness of biotechnological microbial-mycelial composition for calves

The purpose of the research was to study the effectiveness of using a microbial- mycelial composition based on filamentous fungi Fusarium sambucinum var. sambucinum 52434 VKPM F-139, Trichoderma reesei LA-531 VKPM F-184, bacteria Lactobacillus paracasei subsp. paracasei VKPM B-2430 and auxiliary components (molasses, zeolite, sodium chloride) for young cattle. As a result, it was shown that adding the developed composition for 30 days at a dose of 1,0 % to the main diet helps to increase resistance to adverse environmental factors, which is manifested by a decreasing in morbidity, increasing productivity and safety of calves.
