(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...

Sheep and goats are popular examples of livestock kept on city farms. In these settings, close contacts between humans and animals frequently occur. Although it is widely accepted that small ruminants can carry numerous zoonotic agents, it is unknown which of these agents actually occur in sheep and goats on city farms in Germany. We sampled feces and nasal liquid of 48 animals (28 goats, 20 sh...

In this paper, we propose a solution to the problem of herding by caging: given a set of mobile robots (called herders) and a group of moving agents (called sheep), we move the latter to some predefined location in such a way that they cannot escape from the robots while moving. We model the interaction between the herders and the sheep by assuming that the former exert virtual “repulsive force...

Hu sheep is one of the most important species in China; it is also listed as one of the 78 nationally protected domestic animals by the Chinese government in 2000. The construction of cDNA expression library of Hu sheep is of great significance for protecting individual genomes, generating transgenic sheep, and conducting clinical research using cDNA from Hu sheep. In this study, the total RNA ...

The diversity of populations in domestic species offers great opportunities to study genome response to selection. The recently published Sheep HapMap dataset is a great example of characterization of the world wide genetic diversity in sheep. In this study, we re-analyzed the Sheep HapMap dataset to identify selection signatures in worldwide sheep populations. Compared to previous analyses, we...

Previous studies based upon competition between different organic anions for biliary excretion in vivo have suggested that all organic anions share a common hepatic secretory mechanism. Corriedale sheep with an inherited defect in organic anion excretion by the liver were used to study this problem directly without the need for competition studies, the results of which are difficult to analyze....

ONCEL, T., G. VURAL: Occurrence of Toxoplasma gondii antibodies in sheep in Istanbul, Turkey. Vet. arhiv 76, 547-553, 2006. ABSTRACT This study was carried out in order to determine the occurrence of Toxoplasma gondii antibodies in sheep in five districts of Istanbul, Turkey. A total of 181 sera taken from sheep were examined for antibodies to Toxoplasma gondii using an enzyme-linked immunosorb...

Sheep betaretroviruses represent a fascinating model to study the complex evolutionary interplay between host and pathogen in natural settings. In infected sheep, the exogenous and pathogenic Jaagsiekte sheep retrovirus (JSRV) coexists with a variety of highly related endogenous JSRVs, referred to as enJSRVs. During evolution, some of them were co-opted by the host as they fulfilled important b...
