Development of the experimental composition based on the mycelial fungi Fusarium sambucinum and evaluation of its efficiency as a means for the prevention of diarrhea in calves

Abstract

The main task in livestock complexes is to ensure the safety of livestock and to obtain healthy young animals. It is known that in the last months of pregnancy in cows, the fetal weight increases by 70-75 %, all the organs of the immune defense and the enzymatic system develop, and, consequently, the general resistance of the newborn young is formed. This underlines the importance of creating optimal conditions for feeding and keeping pregnant animals. Therefore, when developing rational measures for the prevention and control of diseases of nascent young animals, it is necessary to consider this complex as a single system, since the physiological immaturity of newborns cannot be further compensated even by ideal growing conditions.The use of a composition based on a mycelial fungus and an organosulfur compound is a promising preventive agent that does not have a pronounced negative effect on the animal's body. The proposed therapeutic two -component composition for pregnant cows consists of selimaccide and a commercial preparation «Milife» containing a culture of the mycelial fungus Fusarium sambucinum strain VKPM F-139. Selimaccide is the diethylammonium salt of N-methylamino-1-phenylmethanesulfonic acid, belongs to the new chemical compounds of the class of aminomethanesulfonates, is a white crystalline powder with a specific odor, well soluble in water, alcohol, dimethylsulfoxide.Daily watering of the proposed composition to pregnant cows 12 days before calving 2 times a day at a dose of 500 cm3 / head with an interval of 6 to 8 hours ensures the birth of calves resistant to gastrointestinal disorders.The aim of the research was to study the effectiveness of the drug, which is a combination of selimaccide and the mycelial fungus Fusarium sambucinum strain VKPM F-139 as a means of preventing gastrointestinal disorders in newborn calves when applied to pregnant cows.
