Research was carried out on 1,684 sheep (1,093 F and 591 M) originating from European Mouflon (Ovis aries musimon), its hybrids with Polish heat sheep and four sheep breeds that are characterized by a mixed wool compared to Polish Merino. All animals were subjected to gene identification factor insulin-IGF-1, in the assessment of allele C and T. In conclusion it should be noted that in the 7 examined breed groups sheep showed no polymorphism alleles and genotypes of insulin-like factor gene IGF-1, limiting its scope to determine the C allele and genotype CC. This result indicates the need for further research in this area in "culture" sheep imported and adapted to Polish conditions and the production environment.
Coproscopic examinations of mouflons Ovis aries musimon from four forest districts of Lower Silesia performed in spring and autumn from 2012 to 2014 demonstrated the presence of pulmonary nematodes and intestinal parasites, including coccidia of the genus Eimeria. Prevalence of pulmonary nematodes (mainly Muellerius capillaris) amounted to 69.78%, intestinal nematodes – 56.11% and coccidia of the genus Eimeria – 44.6%. The number of oocysts, eggs of intestinal helminths and larvae of pulmonary nematodes was low. Most frequently the parasites occurred in mouflons from the Jugów forest district, which is related to contact with sheep grazed in the area.
