The increasing number of sheep (Ovis aries) in the reindeer (Rangifer tarandus tarandus) herding area in North Finland and supplementary winter feeding of reindeer in corrals shared with sheep causes potential for crossinfection of gastrointestinal nematodes between reindeer and sheep. The aim of this study was to elucidate this potential. The study included 46 animals, of which 12 reindeer and...

Although sheep (Ovis aries) have been one of the most exploited domestic animals in Estonia since the Late Bronze Age, relatively little is known about their genetic history. Here, we explore temporal changes in Estonian sheep populations and their mitochondrial genetic diversity over the last 3000 years. We target a 558 base pair fragment of the mitochondrial hypervariable region in 115 ancien...

This study was undertaken to determine the prevalence and diversity of Eimeria species in sheep in Tabriz suburb. The prevalence of ovine parasitism due to Eimeria spp. was estimated in 240 sheep aged less than six months to over 12 months, in a period of one year (2003-2004). The samples were collected from pre-slaughtered sheep in Tabriz slaughterhouse and transferred to the parasitology labo...

AIM To investigate whether single-dose intravitreal injections of bevacizumab and ranibizumab transfer into milk. METHODS This study included lactating 12 sheep and a single 3-month old suckling lamb of each sheep. Two groups consisting of 6 sheep and their lambs were constituted; the ranibizumab group and the bevacizumab group before the administration of intravitreal injections, blood and m...

BACKGROUND: Camel and sheep have high disperse and tolerance in tropical regions. But different results of harsh condition tolerance ability of them have been reported. OBJECTIVES: The objective of this study was to determine the heat stress tolerance in camel and sheep by evaluating changes in blood serum metabolites and to report and compare the serum biochemical profile of sheep and camel du...

BACKGROUND Comparatively little is known about the prevalence or the molecular characteristics of the zoonotic pathogen E. coli O157:H7 in the sheep reservoir. To investigate this and determine the host specificity of subclones of the bacterium, we have conducted a slaughterhouse prevalence study in sheep and compared the collected isolates to O157:H7 previously isolated from cattle and human p...

Background: Epidemiological studies have used farmer estimates of the prevalence of lameness in their flocks. This assumes that farmers can identify lame sheep. Eight movie clips of sheep with locomotion from sound to moderately lame were used to investigate the ability of farmers and sheep specialists to recognise lame sheep. Each participant was asked to complete a form and indicate, for each...

b-lactoglobulin (coded by the b-lg gene) is the major milk whey protein in ruminants. studies have shown that this protein is polymorphic in many breeds of sheep as a result of a single base pair substitution in the b-lg gene that also gives rise to rsai restriction fragment length polymorphism (rflp). blood samples were collected from 391 animals belonging to 5 iranian and 6 russian sheep bree...

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...

Abstract Background Sheep milk is a nutritional and health-promoting food source for humans. The DEATH superfamily conserved protein family, some of its members are closely related to lactation. Systematic studies the important further understanding functions in mammary gland during lactation; however, there currently lacking. Results Herein, 74 were identified sheep, phylogenetic analyses indi...
