[Changes of the clinico-biochemical indices in the rumirid juice and urine in experimental aflatoxicosis of dairy cows].

The health condition and course of fermentation processes in the rumen were studied in four cows of the Red Spotted breed at the age of four to nine years. The clinico-biochemical indices in the rumen liquor and urine were used. The experimental animals were exposed to a mixture of aflatoxins applied in the dose of 200 mg B1 and 80 mg B2. The toxic action of aflatoxins manifested itself as inappetence, increased temperature, changes in the pulse and respiration rate and reduced activity of the proventriculi. Diarrhoea was observed in two animals. The pH value, total acidity and ammonia level in rumen liquor ranged within the limits of reference values. The significant drop of the production of volatile fatty acids with changes in their proportions and a reduction of the acetic acid level with a simultaneous increase of the percentage of butyric acid testity to a disorder in the activity of rumen microflora. The reduction of the number of infusorians as a biological indicator of fermentation processes proves the correctness of this assumption. During the elimination of aflatoxins through the kidneys the function of the kidneys is impaired, showed proteinuria, ketonuria, glycosuria and haematuria.
