MODEL OF ESTIMATION OF RISK OF DEVELOPMENT OF COMPLICATIONS WHEN DYSPEPSIA IN CALVES
To ensure the foodsecurity of the Russian Federation, the problem of the conservation andrational use of the biological potential of farm animals is one of thepriorities. The conditions of development of calves in 1 month of life isdetermined by both the health and productive longevity of cattle. In thenosological structure of the pathology of young cattle one of the first placesis occupied by gastrointestinal diseases. Questions assessing the risk ofdeveloping complications in calves with gastrointestinal diseases in veterinarypractice always remain relevant. Firstly, it is connected with the populationhealth of the livestock of young stock as a whole, secondly, with theexpediency of spending on treatment and preventive measures in the agriculturalorganization. The non-metric system of «integral indicators» characterizing theclinical course of these diseases was developed by us for the rapid tracking oftrends indicating the risk of complications. It included an assessment of theseverity of signs of dehydration (exsiccosis) of the body of calves and thequalitative characteristics of their feces. The combination of non-metric«integral indicators», expressed in points, represented a rating scale from«calf healthy» to «critical condition with a poor prognosis». In the examinedanimals (n=50), the use of a scale for assessing the physiological state ofcalves with dyspepsia of various genesis allowed for an in-depth analysis ofthe clinical indicators of the disease, identifying the risk groups fordeveloping complications and adverse outcomes of the disease. It was shown thatthe examined calves with a background total coefficient of 22–23 points on thescale of assessing the severity of signs of dehydration (exsiccosis) of thebody and the qualitative characteristics of their feces are practicallyhealthy. In calves with a background total coefficient of 18–21 points,disorders of the physiological state caused by the disease were minimal, theprobability of a favorable outcome («recovery») by the 14th day was 52.4 %.Calves with a background total coefficient of 14–17 points were assigned to therisk group for the development of complications and adverse outcomes of thedisease. In 23.8 % of cases, animals were stunted, in 52.4 % ofcases, calves were diagnosed with dysbacteriosis. The death of calves wasobserved in 9.5% of cases.
