| الوصف: | The research was carried out in the dairy complexes of Lednevo breeding farm in the Yuryev- Polsky district, the Vladimirov region. The purpose of the study was to scientifically substantiate the influence of mycotoxins on quality indicators of milk in cows in a large livestock complex. At each of the complexes, 20 cows were selected. The milk samples were taken to determine the content of protein, fat, casein, albumin, globulins, lactose, total solids, dry skimmed milk residue using automatic milk composition analyzer (Combi Milkoscan, FossElectric, Denmark). Analysis of mycotoxin residues in milk was carried out using liquid chromatography mass spectrum. To determine hematological parameters and perform biochemical tests, BioSystemsA25 automatic analyzer (USA) was used. The results of automatic Foss analyzer showed a decrease in dry matter content in milk from cows that received feed with a higher concentration of mycotoxins (10.44 0.22 versus 14.71 0.45 %). Thus, mycotoxins in high concentrations affect amino acid metabolism. Threonine, an essential amino acid obtained from aspartate in bacteria and plants, is metabolized to form glycine and serine, which have a great influence on metabolic processes. Thus, feeding lactating cows with fodder containing mycotoxins reduced feed consumption, milk yield, and also had negative effect on hematological and biochemical blood parameters of experimental cows. |
