Trypanotolerance
A trypanotolerant organism is one which is relatively less affected by trypanosome infestation. By host In humans In livestock Some breeds are known for their trypanotolerance. This is especially important in Africa where a few particular trypanosomes are major economic and agricultural pests. Trypanotolerant livestock breeds * N'Dama cattle * West African Dwarf goats * West African Dwarf sheep (Djallonké) * Cameroon sheep History of genetic research Trypanotolerance had previously been achieved through normal livestock breeding in cattle, but genetic analysis was becoming a serious option in the 1980s. The effort that would eventually bear fruit began with a conversation between Peter Brumby - then at the International Livestock Centre for Africa - and Morris Soller in 1985. This was followed by the opening of the shortlived International Trypanotolerance Center in the Gambia The Gambia,, ff, Gammbi, ar, غامبيا officially the Republic of The Gambia, i ...

Morris Soller
Morris Soller (1931) is a research professor in the Department of Genetics of the Hebrew University of Jerusalem. He is especially interested in livestock- and crop- genetics including trypanotolerance in cattle. Early life and education Soller was born in 1931 in Manhattan, New York City, USA At the age of 12 he was first inspired to learn about genetics by reading The Theory of the Gene by Thomas Hunt Morgan. . While an undergraduate he read Jay Laurence Lush's ''Animal Breeding Plans'' and learned much from it and interestingly would receive the award named for Lush 50 years later see below. Soller also learned much from the writings of Ronald Fisher and Sewall Wright during this time. In 1951 he earned a Bachelor's Degree in Agriculture and then in 1956 both a Master's Degree in Applied Statistics and a Doctorate of Philosophy in Animal Breeding from Rutgers University. He would later return to his birth country for further postdoctoral education at Indiana University an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
N'Dama
N'Dama is a breed of cattle from West Africa. Other names for them include Boenca or Boyenca (Guinea-Bissau), Fouta Jallon, ''Djallonké'' or ''Djallonké cattle'', Fouta Longhorn, Fouta Malinke, Futa, Malinke, Mandingo (Liberia), and N'Dama Petite (Senegal). Originating in the Guinea highlands, they are also found in southern Senegal, Guinea-Bissau, the Gambia, Mali, Ivory Coast, Liberia, Nigeria, and Sierra Leone. They are Animal trypanosomiasis, trypanotolerant, allowing them to be kept in tsetse fly-infested areas. They also show superior resistance to ticks and the diseases they carry and to ''Haemonchus contortus'' stomach worms. The Senepol breed of beef cattle developed on the Caribbean Island of St. Croix has long been thought to originate from crosses between N'Dama cattle, imported in the late 19th century, and Red Poll cattle, but it is actually an admixed breed between a European taurina (Red Poll) and zebu. Reproduction The age of first calving is 3.5 years in Uppe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
West African Dwarf Sheep
The West African Dwarf or Djallonké is an African breed or group of breeds of domestic sheep. It is the dominant breed of West and Central Africa. This breed is primarily raised for meat. The Cameroon or Cameroon Dwarf is a breed within this group.Valerie Porter, Lawrence Alderson, Stephen J.G. Hall, D. Phillip Sponenberg (2016)''Mason's World Encyclopedia of Livestock Breeds and Breeding''(sixth edition). Wallingford: CABI. . Characteristics The West African Dwarf is generally white or piebald, the front half being black and the back half white. However, skewbald (tan on white) and the black belly pattern are found, and the Kirdi type are specially selected to be entirely black. Rams weigh approximately , have a well-developed throat ruff and are usually horned. The horns are wide at the base, curve backwards, outwards and then forwards again, with a maximum of one and a half coils. Ewes weigh about and are usually polled (hornless), but may have slender short horns. The ears a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disease Tolerance
Tolerance to infection, or disease tolerance, is a mechanism that host organisms can use to fight parasites or pathogens that attack the host. Tolerance is not equivalent to resistance. Disease resistance is the host trait that prevents infection or reduces the number of pathogens and parasites within or on a host. Tolerance to infection can be illustrated via comparing host performance versus increasing load. This is a reaction norm in which host performance is regressed against increasing disease burden. The slope of the reaction norm defines the degree of tolerance. High tolerance is indicated as a flat slope, i.e., host performance is not influenced by increasing burden. Steep downward slope indicates low tolerance in which host performance is strongly reduced with increasing burden. An upward slope indicates overcompensation in which a host increases its performance with increasing burden. Genetic variation in tolerance and its correlation with resistance, can be quantified usi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Revue D'élevage Et De Médecine Vétérinaire Des Pays Tropicaux
A revue is a type of multi-act popular theatrical entertainment that combines music, dance, and sketches. The revue has its roots in 19th century popular entertainment and melodrama but grew into a substantial cultural presence of its own during its golden years from 1916 to 1932. Though most famous for their visual spectacle, revues frequently satirized contemporary figures, news or literature. Similar to the related subforms of operetta and musical theatre, the revue art form brings together music, dance and sketches to create a compelling show. In contrast to these, however, revue does not have an overarching storyline. Rather, a general theme serves as the motto for a loosely-related series of acts that alternate between solo performances and dance ensembles. Owing to high ticket prices, ribald publicity campaigns and the occasional use of prurient material, the revue was typically patronized by audience members who earned more and felt even less restricted by middle-cla ...

Annual Reviews (publisher)
Annual Reviews is an independent, non-profit academic publishing company based in San Mateo, California. As of 2021, it publishes 51 journals of review articles and ''Knowable Magazine'', covering the fields of life, biomedical, physical, and social sciences. Review articles are usually “peer-invited” solicited submissions, often planned one to two years in advance, which go through a peer-review process. The organizational structure has three levels: a volunteer board of directors, editorial committees of experts for each journal, and paid employees. Annual Reviews' stated mission is to synthesize and integrate knowledge "for the progress of science and the benefit of society". The first Annual Reviews journal, the ''Annual Review of Biochemistry'', was published in 1932 under the editorship of Stanford University chemist J. Murray Luck, who wanted to create a resource that provided critical reviews on contemporary research. The second journal was added in 1939. By ...
