Two-year observations were made on the seasonal and age dynamic of the basic helminth infections on a pasture complex of the village of Bochkovtsi , Veliko Turnovo district. The methods of F ulleborn , Berman , successive washing, and MacMaster were employed to investigate a total of 2198 fecal samples taken from 50 permanently marked lambs, weaned lambs, and ewes. The parasite burden and the species composition of the helminths were established via complete post-mortem examinations, resp., helminthologic necropsies of 19 ewes, 7 weaned lambs, and 5 lambs. Studied were also the surrounding field conditions in order to discover and investigate the biotopes. A total of 517 fresh-water snails of the Limnea truncatula species and 640 land ones of the Helicella obvia species were examined. The helminth fauna was established with the various categories of animals raised on the pasture complex along with the seasonal dynamic of the basic parasitic diseases. A programme for the prophylaxis and therapy was worked out.
在大特尔诺沃区博奇科夫齐村的一个牧场综合体上，对基本蠕虫感染的季节动态和年龄动态进行了为期两年的观察。采用富勒伯恩法、伯曼法、连续冲洗法和麦克马斯特法，对从50只永久标记的羔羊、断奶羔羊和母羊采集的总共2198份粪便样本进行了调查。通过对19只母羊、7只断奶羔羊和5只羔羊进行完整的死后检查，即蠕虫学尸检，确定了蠕虫的寄生虫负荷和种类组成。还研究了周围的田间条件，以发现和调查生物群落。共检查了517只截口椎实螺和640只明显圆口螺。确定了牧场综合体上饲养的各类动物的蠕虫区系以及基本寄生虫病的季节动态。制定了预防和治疗方案。
