Abstract

Formulation of the problem. The key to successful development of sheep breeding is veterinary welfare of livestock. Among contagious etiology diseases of sheep a significant place occupy ectoparasitic diseases, including melophagosis. Invasion causing considerable economic damage to the industry due to the loss of meat and wool productivity, loss of young sheep. Most of the research results show that melophages parasitize on sheep throughout the year, but melophagic invasion has expressed seasonality. So the authors suggest that the peak population of adult sheep’s parasites occurs in May. After haircut intensity of invasion decreases and becomes minimum in July and August. Increasing the number of affected sheep occurs gradually and in November extensity of melophagosic infestation is greatly increased and reaches a maximum in the spring. Therefore, definition of depending of indicators invasiations of sheep by melophagosic agent from season in terms of Ukraine is the actual direction of research. The purpose of research – explore the indicators of extensiveness and intensity of melophasosic infestation in sheep throughout the year and find out the features seasonal manifestation of enthomoses. Materials and methods. Research conducted during from March 2016 to February 2017 in conditions of LTD «Druzhba» of Dykanka region of Poltava area, melophagosic troubled about the sheep. Parasitologic research conducted in the Scientific Laboratory of Parasitology and Veterinary and Sanitary Expertise Faculty of Veterinary Medicine of Poltava State Agrarian Academy. When examining of livestock key indicators of sheep lesions by melophagosic pathogen were extensiveness and intensity of infestation (EI and II). Results and discussion. Conducted studies have established that the degree of infestation of sheep melophagosic agent depended on the season. Thus, the maximum exposure of extensiveness and intensity of melophagosic infestation was recorded in the winter-spring season (EI – 58.88–66.66 %, II – 153.06±3.1 – 153.06±3.13 ex. at animal, respectively ) and set the minimum in summer (EI – 12.38 %, II – 12.38±1.04 ex. at animal). Autumn extent of infection of sheep after summer began gradually to grow and amounted to 31.66 %, 70.71±3.38 ex. parasites. Conclusions. 1. Melophagosis of sheep in Poltava region registered during the year, but infestation occurs with expressed seasonal dynamics. 2. The maximum performance of extensiveness of melophagosic infestation in sheep recorded in March and February (up to 71.67 %), minimum – in June (8.33 %). 3. Indicators of melophagosic infestation were increased in April–May (up to 212.21±3.14 ex. at animal) and declined in June and July (up to 9.30±1.22 ex.). Prospects for further research. Advisable to consider in further research about study the therapeutic efficacy of modern insecticides at melophagosis of sheep.
