this survey was carried out to determine the infection rate of coenurus cerebralis in urmiaabattoir, west azerbaijan, iran. a total of 402 sheep heads were examined and the number ofc. cerebralis cysts per each head was recorded. thirty three sheep heads were examined eachmonth during 12 months from 2006 to 2007. of 402 heads, a number of 75 heads (18.65%)were infected with c. cerebralis. the c...

Broad diversity among breeds of sheep is a precious industry resource. This breed diversity can be managed to increase performance and profit through use of crossbred ewes mated to rams of a terminal sire breed. Differences among breeds in performance for survival, growth, carcass, wool, and reproductive traits are due to the unique genetic history associated with each breed. Beneficial genetic...

This study evaluated The association of breed, sex, age and location herd/flock (Village. peri-urban sales point) with prevalence distribution ticks in sheep goats Abeokuta its environs, A total 300 were randomly selected from the three locations. estimated age, breeds each animal determined. Thereafter, they examined for presence ticks, Ticks collected into universal bottles containing 1% form...

b ackground: the aim of the present study was to determine the molecular characteristics of echinococcus granulosus from paraffin-embedded tissues of hydatid cysts isolated from human and protoscoleces of hydatid cysts from sheep, cattle and camel isolates using pcr- rflp of its1- rdna analysis in golestan province, northern iran. m ethods: e . granulosus isolates from human patients infected w...

acetyl-coenzyme a carboxylase α (acc-alpha) is considered as the key regulatory enzyme in fatty acid biosynthesis. acc-alpha gene is located on caprine chromosome 11 and is polymorphic in many goat breeds. in the current study, we aimed to find possible single nucleotide polymorphisms (snps) in the exon 1 region of the acc-alpha gene in iranian mahabadi goat breed. genomic dna was extracted fro...

background: toxoplasmosis is a worldwide spread disease. the present study examined the prevalence of toxoplasma gondii infection among animals of ediblemeat (cattle and sheep) in chaharmahal va bakhtiari province (southwest of iran) in 2012. furthermore, we attempted for the first time to identify this parasite from the meat products in the province. methods: the tongue, brain, femur muscle an...

abstract the whole blood potassium concentration has shown the bimodal distribution in sheep, which has been classified into lk and hk types; hk allele is recessive to lk with a single gene inheritance. this polymorphism showed different behavior in different environment, which could be due to adaptation process. this research was conducted on the zel and kermani breed research station, which k...

This study estimated the magnitude of sexual dimorphism in a relict sheep from Catalunya (NE Spain), called Fardasca,using geometric morphometric techniques. For these analyses, a total of 18 skull specimens (2 adult males and 16 females) were studied. Our results suggest that the breed is not cranially dimorphic, so sex determination using landmarks described here as criteria is likely to yiel...

in this research thirty specimens of duodenum of lori-bakhtiari sheep from abattoir were collected. the specimens were selected from male healthy sheep and aged 1 years. after collecting them and determining of three parts of duodenum (cranial, descending and ascending parts), the lengths of them were measured. for histological studies, each part of duodenum divided to two centimeter pieces and...
