Fig. 1
Fecal egg counts (EPG, eggs per 1g of faeces; mean + SEM) of strongyle nematodes detected in ewes and their lambs throughout the grazing season (May-October). Treated animals received mineral licks containing the extracts of the plants with anti-parasitic properties (Star Bloc Phyto Vers), while their respective control animals received standard mineral licks (Lisal Se) ad libitum. ND - not detected. Within months, means denoted by different letters are significantly different (P<0.05)

Prevalence (%) of strongyle nematodes infections in ewes and their lambs determined by coproscopic examination during the grazing season (May-October). Treated animals received mineral licks containing the extracts of the plants with anti-parasitic properties (Star Bloc Phyto Vers), while their respective control animals received standard mineral licks (Lisal Se) ad libitum. ND - not detected.

Prevalence (%) of Moniezia spp. infections in ewes and lambs determined by coproscopic examination during the grazing season (May-October). Treated animals received mineral licks containing the extracts of the plants with anti-parasitic properties (Star Bloc Phyto Vers), while their respective control animals received standard mineral licks (Lisal Se) ad libitum. ND - not detected. Within months, values denoted by different letters are signifi cantly different (P<0.05)
