Fecal egg counts for gastrointestinal nematodes are associated with a polymorphism in the MHC-DRB1 gene in the Iranian Ghezel sheep breed

Genetic variation among sheep breeds in resistance to gastrointestinal nematodes (GIN) has been demonstrated in several production environments. Relationships between the ovine major histocompatibility complex and resistance to GIN have been studied, but few studies have systematically examined this issue in less-developed and semi-arid regions. The aim of the current study was to explore assoc...

Use of Microsatellite Polymorphisms in Ovar-DRB1 Gene for Identifying Genetic Resistance in Fat-Tailed Ghezel Sheep to Gastrointestinal Nematodes

This study was designed to identify genetically resistant animals to gastrointestinal nematode (GIN) infections using microsatellite polymorphisms of Ovar-DRB1 gene in Iranian Ghezel sheep breed lambs. In the present study 120 male Ghezel lambs were at 4 to 6 months of age randomly selected from six different sheep flocks in East Azerbaijan province (n=20 per flock). These lambs were naturally ...

Microsatellite Polymorphism in DRB2 Gene and its Relation to Haemonchus Contortus Parasites Fecal Egg Count in Iranian Ghezel Sheep

Gastrointestinal parasites are one of the main sources of economic decline in sheep production around the world. Resistant sheep do not completely reject the disease; they only harbor fewer parasites than susceptible sheep and therefore have a lower fecal egg count. The present research was designed to evaluate microsatellite polymorphism in intron 5 of DRB2 gene and its correlation with H. con...

Genetic Polymorphism of GDF9 Gene in Iranian Moghani Sheep Breed

The families of TGF-β proteins are the most important growth factors in the ovary for growth and differentiation of early ovarian follicles. Three related oocyte-derived members of the transforming growth factor-β superfamily namely growth differentiation factor 9 (GDF9), BMP15 and BMPR-IB have been shown to be essential for follicular growth and ovulation. Different mutations in the GDF9 gene ...

Association of the Polymorphism Kiss1 Gene Exon 1 with Twin Traits in Sanjabi, Ghezel Breed Sheep by PCR–SSCP Technique

The Kiss1 gene is one of the known affective gene in fertility, which affects ovulation and multiplication. In this study, Blood samples were collected from 100 sheep of Sanjabi in Mehregan breeding station in Kermanshah province and 50 sheep Ghezel breeding station of Urmia University. After DNA extraction, the polymerase chain reaction (PCR) was used for specific primers amplification of 331 ...
