The mechanism of influenza virus (INFV)-induced immunosuppression and the mode of inosiplex action against INFV infection were studied. INFV suppressed both anti-lipopolysaccharide and anti-sheep erythrocyte antibody production in mice. INFV infection caused viral mRNA synthesis and increased total RNA synthesis in lymphocytes, but total mRNA synthesis was decreased. The translational ability o...

Goats and sheep rank third and fourth in terms of global milk production from different species, but unlike cow milk, which has stringent hygiene and quality regulations, microbiological standards for the production and distribution of goat milk and sheep milk are more relaxed. Difficulties in managing the sanitary quality of sheep and goat milk derive from a series of factors including the low...

The objective of this paper is to evaluate the productive and reproductive performance major constraints indigenous sheep in Ethiopian perspective. Ethiopia home for at least 9 breeds 14 traditional populations. Sheep are second most important species livestock next cattle Ethiopia. productivity mostly based on sheep. age first sexual maturity may be affected by weaning season post nutrition th...

Numerous gram-negative bacteria communicate and regulate gene expression through a cell density-responsive mechanism termed quorum sensing (QS), which involves the synthesis and perception of diffusible N-acyl-homoserine lactones (AHL). In this study we genetically and physiologically characterized the Burkholderia thailandensis DW503 QS network. In silico analysis of the B. thailandensis genom...

There is a sex difference in the hypothalamo-pituitary-adrenal (HPA) axis of many species, although there are sparse data on the sheep. In the present study we have compared the HPA axes of intact and gonadectomised adult male and female sheep at the level of the median eminence, pituitary and adrenal glands using a variety of in vitro approaches. The concentration of arginine vasopressin (AVP)...

Low-input lambing management was the focus of the 2007 Sheep Symposium at the joint annual meetings of the American Society of Animal Science, the American Dairy Science Association, the Asociación Mexicana de Producción Animal, and the Poultry Science Association held in San Antonio, Texas, on July 8 to 12, 2007. The purpose of this symposium was to bring together biologists and managers who c...

Despite the importance of carnivores in terrestrial ecosystems, many nations have implemented well-coordinated, state-funded initiatives to remove predators, largely because of conflicts with humans over livestock. Although these control efforts have been successful in terms of the number of carnivores removed, their effects on the viability of the industries they seek to protect are less under...

OBJECTIVE The present study aimed to estimate and compare the economic impact of Schmallenberg virus (SBV) in different sheep production holdings using partial budget and gross margin analyses in combination with production models. PARTICIPANTS The sheep production types considered were lowland spring lambing, upland spring lambing and early lambing flocks in the UK, and grass lamb flocks of ...

Small ruminants (goats and sheep) form an important economic and ecological niche in agricultural systems throughout the developing countries. Their current contribution is not commensurate with the potential capacity for higher levels of production. The context for productivity enhancement and increased socioeconomic contribution relates to large population size, wide distribution across vario...
