SUMMARY In this study, Coxiella burnetii seroprevalence was assessed for dairy and non-dairy sheep farm residents in The Netherlands for 2009-2010. Risk factors for seropositivity were identified for non-dairy sheep farm residents. Participants completed farm-based and individual questionnaires. In addition, participants were tested for IgG and IgM C. burnetii antibodies using immunofluorescent...

Aneurysm of the pulmonary artery is a rare condition in animals, and to our knowledge it has never been reported association with neoplasia. This report describes case an adult female sheep “Churra Galega Bragançana” breed aneurysm associated lung cancer (ovine adenocarcinoma).

In sheep, cervical artificial insemination (AI) involves depositing semen at the opening, as it is not possible to traverse cervix due its complex anatomy. However, internationally this method yields low pregnancy rates when frozen-thawed used. An exception in Norway, which vaginal deposition of a natural estrus around 70%. As and secretions are principal factors influencing sperm transport sit...

During the early days of the development of the Australian Merino sheep, selection of sheep was based on subjective classing, which is still in practice. Showing of stud animals was also based on subjective classing. With this method some characteristics become fashionable, because of the perceived positive associations with production and fitness. However, some can only be described as fancy t...

Massese is an Italian dairy sheep breed characterized by animals with black skin and horns and black or apparent grey hairs. Owing to the presence of these two coat colour types, this breed can be considered an interesting model to evaluate the effects of coat colour gene polymorphisms on this phenotypic trait. Two main loci have been already shown to affect coat colour in sheep: Agouti and Ext...

Biological control of parasitic nematodes of livestock is currently under development and represents another tool that may be integrated into helminth parasite control strategies. This paper presents a brief introduction to commercial sheep farming in South Africa and currently available nematode parasite control methods. These include the FAMACHA clinical assay, strategies of pasture managemen...

the genotypes of the melatonin receptor 1a (mtnr1a) were determined by pcr-rflp in the native iranian shall  and karakul breeds of sheep . blood samples were collected from 60 karakul and 50 shall breeds. genomic dna was extracted based on the guanidin thiocyanate-slica gel method. after pcr reaction, pcr products were digested by the mnl1 restriction enzyme. the mtnr1a locus had two genotypes ...

Variation in ovulation rate of ewes was studied with particular reference to the heterosis effect in a 3-breed (Dorset Horn, South Australian Merino, Corriedale) experimental sheep population. For the population as a whole, heterosis effect on the young (1 1/2 year-old) ewes (+0.17 k 0.06** ova, or 14.5%) was similar to that on the mature (5 1/2 year-old) ewes (+0.19 f 0.06** ova, or 12.5%), in...

Sheep of the Pantaneiro breed and seven other breeds, raised in the State of Mato Grosso do Sul, Brazil, were genotyped using eight microsatellite loci. The aim of the present study was to determine the genetic variability, phylogenetic relationship, and patterns of gene introgression and miscegenation among the animals surveyed, to obtain information about the genetic structure of locally adap...

The aim of this study was to determine the prevalence of trematodes and cestodoses in slaughtered sheep from the region of Sarajevo. The study was carried out on a total of 699 indigenous sheep of pramenka breed, of various sex and age. After parasitological section, visual examination and palpation of the liver, the prevalence rate of Fasciola hepatica, Dicrocoelium dendriticum, hydatid cysts ...
