Псороптоз овець і диких кіз: клінічний прояв та лікування в умовах антропобіоценозів

Abstract

Ураженість овець і диких кіз псороптесами становила 100 % з різним ступенем: від тотального до легкого. Летальність серед овець становила 3,2 %, а серед диких кіз – 5,9 % за генералізованої форми. Застосовані «Іверон-10» і «Дектомакс» ін’єкційні у дозі 0,2 мл на 10 кг маси тіла тварини, двократно, показали 100 % ефективність.

Among the ectoparasitoses of small ruminants, psoroptosis has an important place - a common acarosis disease caused by a permanent ectoparasite of the genus Psoroptes (Psoroptidae: Acariformes). This highly contagious invasion causes huge economic losses in many countries with developed sheep breeding. The aim of the work is to study the distribution and analyze the clinical signs in psoroptosis in sheep and wild goats. Research objectives: to determine the effectiveness of drugs in psoroptosis of sheep and wild goats in conditions of anthropobiocenoses. The material was skin scrapings from 63 sheep (Ovis aries) of fine-fleece breeds: Prekos and Romanovskaya, which belonged to the Scientific and Production Center of Kharkiv State Zooveterinary Academy (SPC KhSZVA) and from 17 wild goats: 14 Siberian mountain goats (Capra siberica) and 3 Marhura (Capra falconeri), which belonged to Government Organization (GO) «Feldman Eco-Park». The acarological study has carried out by the compressor method using a 50 % aqueous solution of glycerin and a 10 % alkali solution (KOH). For the treatment of sheep and wild goats, macrolides «Iveron-10», «Dectomax» were used at a dose of 0.2 ml per 10 kg of animal body weight, twice at 30 and 14 day intervals, respectively. In addition, a synthetic pyrethroid «Butox-50» by the bathing method in water emulsion (twice at 10 day intervals) after shearing sheep, in diluted 1 ml per 1 liter of water ex tempore. The infestation of sheep and wild goats by Psoroptes ovis mites (Hering, 1838) in 2017–2019 was 100 % with varying degrees of body surface damage. In 65.1 % of sheep of the SPC KhSZVA, hair loss was observed on 80–100 % of the body surface, in 28.6 % of animals – 50–79 % of the surface, 6.3 % – less than 50 % of the body surface. In 94.1 % of wild goats of the GO «Feldman Eco-Park», lesions were recorded up to 50 % of the body surface, and in 5.9 % – total lesion. Total lesion in wild goats was characterized by lesions of the surface of the head, ears and neck with significant keratinization of the skin to the inner layers with deep cracks and bleeding, and in sheep, by lesions of the entire surface of the body. Mortality in sheep was 3.2 %, and in wild goats - 5.9 % with generalized form. The applied treatment regimens of sheep and wild goats for psoroptosis with injectable preparations «Iveron-10» and «Dectomax», respectively, at a dose of 0.2 ml per 10 kg of animal body weight, twice at 30 and 14 day intervals with additional bathing of sheep in water emulsion of «Butox-50» (twice at 10 day intervals) showed 100 % efficiency.
