Item The population of laying hens loses important genes: A case history(Journal Article, 1997) Sorensen, P.Item Sustainable animal agriculture and crisis mitigation in livestock-dependent systems in southern Africa(Conference Proceedings, 2001-03) Banda, J.W.; Chagunda, Mizeck G.G.; Kamwanja, L.A.; Phoya, R.K.D; Safalaoh, A.C.L.These proceedings contain papers, abstracts and posters of the Regional Conference on Sustainable Animal Agriculture and Crisis Mitigation in Livestock-dependent Systems in Southern Africa that took place at Malawi Institute of Management (MIM) in Lilongwe, Malawi, from 30th October to 1st November 2000. A keynote paper opens each theme and is followed by scientific contributions, short communications, and abstracts. Posters are published as short communications and/or abstracts. These proceedings are organised as follows: Session 1 Livestock Management and Improvement (16 papers) Session 2 Policy Analysis, Socio-economics and Sustainable Integrated Animal Health (4 papers) Session 3 Crisis Mitigation in Livestock-dependent Systems - Held as a mini workshop within the conference (2 papers) Session 4 Product Enhancement and Human Resources Development (4 papers) Session 5 Short Communications (4 papers) Session 6 Abstracts (10 abstracts)Item Village chicken production systems in Ethiopia: 2. Use patterns and performance valuation and chicken products and socio-economic functions of chicken(Journal Article, 2003-01-20) Dessie, Tadelle; Tadesse, M.; Yami, A.; Peters, Kurt J.Item Indigenous chicken in Ethiopia: Genetic potential and attempts made at improvement(Journal Article, 2000-03-01) Dessie, Tadelle; Yami, A.; Peters, Kurt J.This paper describes the rural poultry production system and the role of scavenging chicken in rural household economy of Ethiopia. Past attempts that have been made to improve the production and productivity of local birds through upgrading (distribution of exotic birds) and crossbreeding in Ethiopia are assessed. The merits and demerits of the different ecotypes of indigenous chicken and their crosses are reviewed. The significance of indigenous birds in the face of extensive importation of exotic birds are assessed. Finally, future areas of research on indigenous chicken is recommended to aid the development of rational utilisation of the local chicken genetic resource.Item Village chicken production systems in Ethiopia: 1. Flock characteristics and performance(Journal Article, 2003-01-15) Dessie, Tadelle; Tadesse, M.; Yami, A.; Peters, Kurt J.Item Village poultry production systems in the central highlands of Ethiopia(Journal Article, 2001) Dessie, Tadelle; Ogle, B.Participatory rural appraisal (PRA), supported by checklists and intensive case studies on individual households, was carried out in three villages at three different altitudes in the central highlands of Ethiopia. The chicken production system in each village is described and the problems are discussed. More than 60% of the families kept chickens, and in most cases the women owned and managed the birds and controlled the cash from the sales. The production systems followed were mainly low-input and small-scale, with 7-10 mature birds per household, reared in the back yards with inadequate housing, feeding and health care. The average egg production per clutch was 15-20, with 3-4 clutches per year. The mean number of eggs set per bird was 12.9 +/- 2.2 (n = 160), depending on the size of the bird and season, and the hatching rate was 80.9% +/- 11.1%, range 44%-100% (n = 160). Poultry meat and eggs were generally accepted and appreciated in all three villages. In addition to the small amount of cash income they provide, scavenging chickens have nutritional, cultural and social functions. The flock composition, price of poultry and poultry products, disease outbreaks and hatching of chicks were strongly affected by season. Disease was cited as the most important problem by most of the members of the community, followed by predation, lack of feed, poor housing, insufficient water and parasites. Disease periodically decimated the flocks, and consequently, about 50% of the eggs produced were incubated in order to replace the birds that had died. The major source of loss in the system was the high mortality of chicks (61%) that occurred between hatching and the end of brooding at 8 weeks of age. The system was characterized by no or few inputs and a low output level. The major input was the cost of foundation stock, but after that virtually no cost was involved. The major source of feed for the birds was from the scavenging feed resource base, which comprised table leftovers, small grain supplements and anything edible from the immediate environment.Item Phenotypic and genetic characterization of local chicken ecotypes in Ethiopia(Thesis, 2003) Dessie, TadelleItem Structures for improving smallholder chicken production in Bangladesh breeding strategy(Conference Paper, 2000) Jensen, H.A.
