BACKGROUND As the prevalence of obesity increases in developing countries, the double burden of malnutrition (DBM) has become a public health problem, particularly in countries such as Guatemala with a high concentration of indigenous communities where the prevalence of stunting remains high. OBJECTIVE The aim was to describe and analyze the prevalence of DBM over time (1998-2008) in indigeno...
Knowledge of the genetic relationship and admixture among neighbouring livestock populations is crucial for conservation efforts. This study analyzed the molecular diversity of fifteen sheep populations (both indigenous and exotic) in Kenya. Blood samples from 582 individuals were genotyped across the 15 microsatellite markers. The expected heterozygosity and Mean number of alleles ranged from ...
Genetic resistance: tolerance to vector-borne diseases and the prospects and challenges of genomics.
Vector-borne diseases in cattle and small ruminants (e.g. trypanosomosis, Rift Valley fever and East Coast fever) are associated with major economic losses in tropical countries, and particularly on the African continent. A variety of control strategies (e.g. management, vaccination and/or acaricide treatments) are used to minimise their negative impacts. These strategies are often associated w...
In the past decade, two pathogens transmitted by Culicoides biting midges (Diptera: Ceratopogonidae), bluetongue virus and Schmallenberg virus, have caused serious economic losses to the European livestock industry, most notably affecting sheep and cattle. These outbreaks of arboviral disease have highlighted large knowledge gaps on the biology and ecology of indigenous Culicoides species. With...
END MARKET OPPORTUNITIES MARKET OVERVIEW Throughout Africa and in humid West Africa in particular, small ruminants must be considered primarily as sources of meat and meat products. There is ample evidence from several African regions that demand for meat is strong and increasing. This reflects greater urbanization and associated higher incomes, which have led to large domestic and internationa...
Background Helminths constitute one of the most important constraints to livestock production in the tropics. Widespread infection with internal parasites in grazing animals, associated production losses, costs of anthelmintics and death of infected animals are some of the major concerns. Current control methods focus on reducing contamination of pastures through anthelmintic treatment and/or c...
Serum lysozyme is widely known for its immuno-protective action. The level is an index of macrophage function and this reflects the status of Reticulo-endothelial (RE) system in the body. It is a ubiquitous bacteriolytic enzyme present in the body fluids and tissues. It acts as an important antimicrobial component in the serum and body fluids. Therefore, the present study was undertaken to dete...
Host factors are regarded as important in shaping the archaeal community in the rumen but few controlled studies have been performed to demonstrate this across host species under the same environmental conditions. A study was designed to investigate the structure of the methanogen community in the rumen of two indigenous (yak and Tibetan sheep) and two introduced domestic ruminant (cattle and c...
A study has been directed towards a better understanding how the Aseel, Kadaknath and White Leghorn immune system responds to multi-determinant antigen, sheep red blood cells. In contemporary commercial poultry production myriad of Viral and bacterial diseases being lingering menace to poultry industry and retort to prevent and control them are needed due to enormous production losses. Our rese...
