Introduction. Fasciolosis causes retardation of growth and the development of young animals, reducing the milk productivity of cows, increasing their susceptibility to infectious diseases. Many authors have noted that meat is infected with Fasciola, opportunistic and pathogenic microflora, can lead to food poisoning.

The goal of the work was to establish the level of vitamins (A, E, B1, B2, C), micro- and macroelements (Ca, Mg, Na, K, Fe, P) changes in meat and liver of cattle infected with fasciolosis.

Materials and methods. Researches to determine the parasitic fauna and morph physiological indicators were conducted in the Laboratory of Parasitology and Helminthology of the Institute of Zoology of the ASM during 1981-2011.

Results of research and discussion. In the Republic of Moldova, the ongoing reforms in the livestock sector over the last 20-25 years (the formation of small and medium farms, as a result of the resettlement of a large number of animals from complexes to private farms) led to increase of the number of livestock in the private sector by 5.8 times compared with the public sector. In the recent years, it was registered a significant increase of the infection of cattle with fasciolosis. Adult cattle (4-6 years) during 1981-1982 were infected with fasciolosis in 32.1% of cases, and in 2010-2011 – in 66.5% of cases, which is higher by 34.4%, and these indices of young animals (23-25 months) were 16.2%, 47.1% and 30.9%, respectively. The reason of it was grazing of animals of different species and ages in the limited territories. It was found, that cattle infested with fasciolosis, the content of vitamin A in the liver decreased by 1.4 times, E – 3.18, B1 and B2 – 1.08 and 1.23, respectively, and C – 2.08, iron – by 3.01 times, phosphorus – 4.17, calcium – 1.56, Mg – 1.04, and the content of Na and K increased by 1.61 and 1.25 times compared to healthy non-infected animals. In the animals meat infected with fasciolosis, the content of vitamin A was 1.83 times lower, E – 1.67, B1 – 1.21, B2 – 1.11, C – 3.73, calcium – 1.60, phosphorus – 1,46, but magnesia, sodium, potassium, and iron, respectively by 1.34, 1.82, 1.30 and 3.14 times higher than in healthy cows.

Conclusions and prospects for further research. Fasciolosis infection of the cattle forms parasitocenosis of Fasciola, opportunistic and pathogenic bacteria (Escherichia coli, Staphylococcus albus, Streptococcus viridans, Bacteria prоteus vulgaris etc.). Considering that fasciolosis as well as other parasitic diseases cause deep morphophysiological changes in the animal’s organism, the quality indicators of meat and offal (vitamins, micro- and macroelements) decrease, we propose that their costs depend on the degree of parasites infestation.

Keywords: cattle, fasciolosis, extensiveness of invasion, vitamins, micro- and macroelements.
