Insulin-like growth factor 1 receptor (IGF-1R) is a main receptor of IGFs family which plays a critical role in the postnatal growth and skeletal growth in many species. However, there are few reports of IGF-1R gene structure and its effects on growth traits in sheep. The objectives of this study were detection of IGF-1R polymorphisms and assessment of their associations with ...

chorioptes bovis is a mite found on the skin of cattle , horse, sheep, goat , camel and wild ruminant. in cattle the root of tail is frequently affected and if untreated the condition may spread to the other parts of the body. c. bovis isolated for the first time from eight dairy cattle 3-7 years old around sharifabad , tehran province.

BACKGROUND Despite the long history of Rift Valley fever (RVF) in Tanzania, extent of its suitable habitat in the country remains unclear. In this study we investigated potential effects of temperature, precipitation, elevation, soil type, livestock density, rainfall pattern, proximity to wild animals, protected areas and forest on the habitat suitability for RVF occurrence in Tanzania. MATER...

Molecular genetics selection on individual genes is a promising method to genetically improve economically important traits in livestock. The insulin like growth factor-I (IGF-I) gene may play important roles in growth of multiple tissues, including muscle cells, cartilage and bone. The objectives of the present study were the estimate the haplotype frequencies of the IGF-I gene polymorphisms i...

Understanding how dispersal patterns are influenced by landscape heterogeneity is critical for modeling species connectivity. Resource selection function (RSF) models are increasingly used in landscape genetics approaches. However, because the ecological factors that drive habitat selection may be different from those influencing dispersal and gene flow, it is important to consider explicit ass...

BACKGROUND Infectious keratoconjunctivitis (IKC) is a clinical condition affecting eyes of domestic and wild Caprinae worldwide, and Mycoplasma conjunctivae is considered the primary causative agent of IKC in sheep, goats and wild Caprinae. Domestic ruminants from high mountain habitats share grazing areas with wild mountain ungulates, such as chamois (Rupicapra spp.), Alpine ibex (Capra ibex) ...
