Epidemiology of echinococcosis and changes in some chimical indicies of muscular tissue and liver of cattle in the Republic of Moldova

Abstract

The study of the parasitological invasions with Echinococcus granulosus in about 8000 cattle have been carried out in different time periods (1986-1987, 2014-2015) in private farms, family household and specialized in milk and beef production farming sectors from the Republic of Moldova. The results of the parasitological research carried out in 1986-1987 have revealed the 33.6% incidence of echinococcosis in adult cattle from farming sectors, 60.6% incidence in farms and 76.5% in cattle from family household (mean 56.9%); the incidence related to bull-calves population (of 23-25 months old) were 8.3%, 17.7% and 21.1% correspondingly (mean 15.7%). In the period 2014-2015, after the restructuring carried out in the livestock, the results show that adult cattle from farms were infested at 74.6%, in individual sector - in 83.7% of cases (mean 79.2%) and young cattle (23-25 months old) - in 31.2% and 37.4% cases correspondingly (mean 34.3%). Compared to 1986-1987 the level of infestation of adult bovines increased, in average, with 22.3% and of young cattle with 18.6% which prove the existence of various outbreaks of parasitic agents (definitive hosts) and lack or irregular conducting of dehelmentization. It was determined that the infested with echinococcosis cattle produce less meat and eatable by-products. Moreover, the content of some vitamins (A, E, B1, B2, C), micro-, macroelements (Ca, Mg, Na, K, Fe, P), chemical indicies (humidity, dry solid matter, proteins, fat, mineral saults) in muscular and liver tussues proved to be considerably changed influencing considerably the animal products’ nutrition value.
