The impact of Fusarium mycotoxins on macro and micro parameters of dairy cattle

The aim of the present study was to evaluate impact on macro and micro parameters dairy cattle when cows consumed total mixed ration (TMR) contaminated with (zearalenone) ZEA deoxynivalenol (DON) for 60 days. Macro indicators included milk composition production blood components, rumen volatile fatty acids (VFAs), DON concentrations in fluid milk. Twenty were fed TMR naturally mycotoxins (ZEA 300 - 500 μg/kg; 102 200 μg/kg). trial lasted Samples blood, fluid, taken three times at intervals 30 obtained results showed that combination affected liver kidney enzymes (p < 0.05) because, days, alkaline phosphatase (ALP) increased by 25%, albumin (ALB) decreased 8.7%, creatinine (CREA) 40%. Rumen ammoniacal nitrogen (NH$_{3}$-N) statistically significantly (43%), whereas acetate acid (2.7%). In reduced yield (20.8%), fats (11.8 %), proteins (3.5%). After days (28.6%), (30%) > 0.05). samples, concentration from 0.97 μg/L (0th day) 1.43 (on 60th day). Based results, it determined Fusarium occurring fodder produced under Lithuanian climatic conditions some indicators.
