Seasonal dynamics of ruminants moniesiosis at the zone of sufficient moisture in the Stavropol regione

Abstract

Moniesiosis of ruminants at the zone of sufficient moisture in the Stavropol regione is represented by two species: M. expansa and M. benedeni. The highest rate of the exten sive invasion is observed among lambs of the current year of birth, which is stated by two peaks - from May to the end of August (100%) only for M. expansa, and from late August to early September to the end of November (25-50%) also by M. benedeni,that is most of the samples contain M. expansa eggs. Throughout the year young ewes and adult stock are infected by two species: M expansa and M. benedeni, with a prevalence of the first species. During the indoor maintenance, the animals are infected within 5-15%. Later, during pasturing from April to the end of November, there are two peaks in morbidity. The first one - from May to the end of August, the second one - from the end of August to the end of November, morbidity is caused by two species with a predominance of M. expansa. The highest intensity of invasion is observed among young ruminants of the current year of birth. At the time of weaning (in July, early August) there are 2.7 specimens of moniezia. In the future, during the indoor maintenance of young ruminants, the intensity is approximately at the same level - 1.3-1.7 specimens of moniezia
