I. The relationship between the heart rate and the energy expenditure of four sheep, S, S,, S, and S1, was studied under conditions known to increase energy metabolism. 2. A close relationship between heart rate and energy expenditure was shown to exist in three of the four sheep tested when energy expenditure was increased by cold exposure and by increased levels of food intake. 3. The source ...

Shiga toxin producing Escherichia coli have been associated with HUS, HC and TTP in human. We found recto-anal mucosal sample in sheep as well in cattle is the main site for E. coli O157 localization. 1246 E. coli isolates from 872 both healthy and diarrheic animals were analyzed, by screening for the presence of Shiga toxin-producing (VT 1 and VT 2) and intimin (eae) genes used Multiplex PCR. ...

The Booroola fecundity gene (FecB) and growth differentiation factor 9 (GDF9) gene belong to the transforming growth factor β (TGF-β) superfamily. The mutations of these genes have additive effects on the prolificacy in sheep. The aim of the present study was to determine the possible mutations of FecB and FecGH genes in Lory sheep breed of the Lorestan province, Iran. Sixty...

background: the prevalence of setariasis in cattle and cerebrospinal nematodiasis in sheep and goats were determined in two geographical regions of iran. methods: in two provinces of iran: mazandaran (zone i) and qazvine (zoneii)   where sheep and goats were suffering from symptoms similar to cerebrospinal nematodiasis, the peritoneal cavities of  763 and 1020 cattle were searched for adult set...

Sumatera Composite (SC) sheep and Barbados Black Belly cross (BC) are two that have half the genetics of local (SL) sheep. Populations with partially same genetic composition sometimes difficult to distinguish. Based on female body size sheep, an analysis was carried out distinguish three breed relationship. The research conducted using SC, BC SL ewe measured in weight 8 sizes. Analysis varianc...

We identified 37 single-nucleotide polymorphisms (SNPs) in sheep and screened 16 individuals from 8 different sheep breeds selected throughout Europe. Population genetic measures based on the genotyping of about 30 sheep from the same 8 breeds are reported. To date, there are no sheep SNPs documented in the National Center for Biotechnology Information dbSNP database. Therefore, the markers pre...

This paper presents a new system architecture and test bed application implementation called Sheep Manager. Sheep Manager system uses NFC technology for the identification of sheep inside a flock as well as sensors for the real-time measurements and recording of raw milk extraction per ewe. All recorded information are then stored into the cloud. Authors also propose an algorithm for sheep bree...

(Photo acknowledgement: Kurrawa Alpacas 2002, Mahoney 2004) Canine attacks on newborn lambs are a problem for sheep farmers, causing substantial economic losses to the sheep industry. Anecdotal evidence indicates that alpacas reduce the losses caused by such attacks when placed within sheep flocks. A study was conducted at two sheep farms in rural NSW where experimental – ewes grazing with alpa...

In this study, it was aimed to determine the effectiveness of transabdominal ultrasonographic imaging on 35th day pregnancy in determining status and number fetuses sheep. 69 Awassi sheep were used study. Sheep mated after oestrus synchronization during breeding season. On 50th days mating, a examination performed twice transabdominally each animal by ultrasonography. with single/multiple offsp...

The distribution of sheep was monitored for three years on part of an unimproved high-country summer range composed of several land units with different phases of degraded tall tussock and short tussock grassland. Sheep distribution was found to be non-random and to vary seasonally. Available dry matter and water content of inter-tussock vegetation were monitored on well vegetated land units fo...
