Monitoring of the bovine digestive diseases on the Transbaikal territory

Abstract

The dynamics of digestive diseases of bacterial etiology among cattle are presented. Statistical, laboratory and annual average data on registered animals with this pathology, mortality and forced slaughter of livestock were analysed for the period 2016-2020. It has been found that digestive diseases of bacterial etiology are prevalent both in young cattle (53.7% to 61.4%) and in adult cattle (43.1% of the total number of diseased animals). The following pathogens were identified on the basis of bacterial tests on biological material: enteropathogenic E. coli (37.8% of the total number of diseased animals) and group D streptococci, E. Faecalis (15.1%). The rest of the herd had associated infections (19.2%) and non-contagious digestive diseases (27.9%). As a result of this monitoring, a high incidence of digestive diseases among cattle in livestock farms in the following districts of the Trans-Baikal Territory was recorded: Akshinsky, Krasnochikoysky, Kyrinsky, Nerchinsky, Olovyaninsky, Priargunsky, Khiloksky, Shelopuginsky, Aginsky. The lowest prevalence of cattle diseases in organizations of various forms of ownership has been recorded in peasant farms in the region (6.8-10.9%). The average number of registered animals with this pathology is recorded in agricultural organizations (26.9-37.6%). A high percentage of these diseases were recorded in households (62.8%). When farms follow the organization of therapeutic and prophylactic measures, housing and feeding hygiene rules, it is possible to ensure the safety and productivity of livestock, high quality and safety of livestock products and to prevent bacterial diseases of the digestive organs.
