De Gruyter Open

From December 2015 Agricultura journal will be published in partnership with De Gruyter Open (degruyteropen.com), the world's second largest publisher of Open Access academic content, and part of the De Gruyter group which has over 260 years of publishing history. De Gruyter Open closely cooperates with the majority of abstracting and indexing services, universities and libraries, providing a wide availability of journal's content and increasing its visibility. Agricultura's full-text articles will be found also at the new address on the De Gruyter Open's platform in following weeks.

The type and the level of invasion by the endohelminths from nematodes and trematodes species were measured in naturally infected sheep by counting the number of eggs in faeces (FEC). The samples of faeces were taken before the spring grazing from randomly selected experimental group of sheep 7 days prior to (Day-7) and on the day of medication (Day 0, n = 15). Closantel (10 mg kg-1 body mass) and mebendazole (15 mg kg-1 body mass) were applied orally. On the 7th and 21st day after the treatment the value FECp was verified in the same group of animals and the degree of reduction with respect to the basal value FECb on the Day-7 and Day 0 (FECRT; 100x (1-(FECp/FECb)) was calculated. All species of endohelminths (Ostertagia, Trichostrongylus, Nematodirus, Strongyloides, Toxocara, Moniezia, Chabertia and Trichuris) found reacted to application of the drug by intensive reduction of the count of eggs excreted, in the range from 94% to 100%.

Key words: sheep, nematodes, anthelminitic, faecal egg count reduction test

Presoja učinka closantela in mebendazola na zmanjšanje fekalnega števila jajčec ovčjih nematod

Pri naravno invadiranih ovcah smo merili fekalno število jajčec (FEC) endohelmintov nekaterih nematodnih in trematodnih parazitskih vrst. Vzorce ovčjega blata smo preiskovali pred spomladansko pašo naključno odbranih poskusnih ovac in sicer sedem dni pred (-7 dni) in na dan peroralne medikacije (dan 0, n=15) closantela (10 mg na kg telesne mase) in mebendazola (15 mg na kg telesne mase). Sedem in 21 dni po medikaciji smo ocenili fakalno število jačec (FECp) v isti skupini ovac in izračunali stopnjo (FECRT) zmanjšanja invadiranosti 100×(1-(FECp/FECb)] glede na izhodišno stopnjo (FECb, na-7 dni oziroma dan 0). Prav vsi endohelminitski rodovi (Ostertagia, Trichostrongylus, Nematodirus, Strongyloides, Toxocara, Moniezia, Chabertia in Trichuris) so reagirali na oba antiparazitika z močno stopnjo redukcije izločanja jajčec v fecesu v razponu med 94% in 100%.
