State of metabolic processes in cattle under the influence of biotic contaminants of feed

Control of feed contamination by micromycetes and bacteria at all stages their preparation, storage, feeding farm animals is an acute issue safety one the principal measures that create opportunity to prevent negative impact on animal health. Therefore, study aimed investigate state metabolic processes in cattle different physiological groups under influence biotic contaminants. The material for research was grain fodder coarse grinding local production, roughage used farm. Veterinary sanitary condition products established based organoleptic, toxico-biological microbiological studies. To determine indicators processes, 3 cows (n = 5–7) with conditions were formed: group I — non-pregnant cows, II pregnant normal pregnancy, III after miscarriage. Biochemical parameters (level total protein, albumin, globulins, vitamins A E) blood serum samples determined spectrophotometrically conventional methods. content inorganic elements aggregate bovine sera performed using X-ray spectrometer ‘Spectroscan MAX’. Laboratory studies have proven presence contaminants base experimental Exceedance maximum permissible levels (max 16.50×104 CFU/g when MPL 5.0×104 CFU/g) toxin-forming (due genera Fusarium, Aspergillus, Penicillium, Mucor, Rhizopus; a 24 isolates microscopic fungi isolated, which showed high toxicity 11.3% weak 20.1% samples) bacterial 18.7×105 5.0×105 CFU/g), structure coliform Salmonella enterica isolated. In consumed excess contaminants, disorders digestive tract (diarrhea) reproductive capacity (abortions first half pregnancy) observed found cattle: increased Iron (on average 1.5 times) Bromine 1.6 levels, decrease concentration vitamin (by 17.4–39.8%), E 10.0–12.5%), most pronounced abortion respectively, Manganese 12.5%) Selenium 30.7%)
