The diet of helmeted guineafowl (Numida meleagris) in the Riemland of the northeastern Free State, South Africa
South African Journal of Wildlife Research, 2008Co-Authors: Helen Prinsloo, Victor Harley, Brian K. Reilly, Timothy M CroweAbstract:This study was conducted to determine the diet of helmeted guineafowl (Numida meleagris) in the Riemland and to establish the effects that these gamebirds may be having on cash crop yield. In the Riemland Farming Community many farmers complain of harvest losses suffered to guineafowl. It was found that the main dietary items during all seasons are corms of weed plants, primarily Cyperus spp. Helmeted guineafowl rely to a large degree on waste maize and germinating wheat during winter when natural food is difficult to find. Although they do not pose any problems with regard to maize Farming, this is not necessarily true for wheat Farming.

The diet of helmeted guineafowl ( Numida meleagris ) in the Riemland of the northeastern Free State, South Africa : short communication

The dynamics of (de)stigmatisation : boundary construction in the nascent category of organic Farming
'SAGE Publications', 2020Co-Authors: Siltaoja Marjo, Granqvist Nina, Lähdesmäki Merja, Kurki Sami, Puska Petteri, Luomala HarriAbstract:This study finds that it is possible for organizations in emerging categories to resist stigmatization through discursive reconstruction of the central and distinctive characteristics of the category in question. We examined the emerging market of organic Farming in Finland and discovered how resistance to stigmatization was both an internal and an external power struggle in the organic Farming Community. Over time, the label of organic Farming was manipulated and the practice of Farming was associated with more conventional and familiar contexts, while the stigma was diverted at the same time to biodynamic Farming. We develop a process model for removal of stigma from a nascent category through stigma diversion. We find that stigma diversion forces the core Community to (re)define themselves in relation to the excluded Community and the mainstream. We also discuss how notoriety can be an individuating phenomenon that helps categorical members conduct identity work and contributes to stigma removal

raw fish eating behavior and fishborne zoonotic trematode infection in people of northern vietnam
Foodborne Pathogens and Disease, 2011Co-Authors: Van Thi Phan, Annette Kjaer Ersboll, Anders DalsgaardAbstract:Abstract Raw fish consumption in restaurants, for example, Sashimi style, is popular worldwide. In Vietnam, raw fish dishes are also traditionally prepared and consumed in private households. However, the habits of eating raw or otherwise inadequately cooked fish can be associated with risks of acquiring fishborne zoonotic trematode (FZT) infection. The present study was done in a fish-Farming Community in Nam Dinh, Vietnam, to obtain information about habits of eating raw fish dishes and risks for human FZT infection. Discussions were held in different groups divided by gender and age on raw-fish-eating behavior. A total of 180 household members were interviewed and their stool samples analyzed to identify risk factors of FZT infection. There was awareness about the risk of liver fluke infections from eating raw fish. However, many older people accepted these risks and continued eating raw fish, as they know effective drug treatment is available. Raw fish dishes are consumed at social gatherings from sha...

animal reservoir hosts and fish borne zoonotic trematode infections on fish farms vietnam
Emerging Infectious Diseases, 2009Co-Authors: Nguyen Thi Lan Anh, Anders Dalsgaard, Nguyen Thi Phuong, Darwin K Murrell, Maria Vang Johansen, Luong To Thu, Tran Thi Kim Chi, S M ThamsborgAbstract:Fish-borne zoonotic trematodes (FZT) pose a risk to human food safety and health and may cause substantial economic losses in the aquaculture industry. In Nghe An Province, Vietnam, low prevalence of FZT for fish farmers but high prevalence for fish indicate that reservoir hosts other than humans may play a role in sustaining transmission. To determine whether domestic animals may be reservoir hosts, we assessed prevalence and species composition of FZT infections in dogs, cats, and pigs in a fish-Farming Community in Vietnam. Feces from 35 cats, 80 dogs, and 114 pigs contained small trematode eggs at 48.6%, 35.0%, and 14.4%, respectively; 7 species of adult FZT were recovered from these hosts. These results, combined with data from previous investigations in this Community, imply that domestic animals serve as reservoir hosts for FZT and therefore must be included in any control programs to prevent FZT infection in humans.

grain yield variation and association of major traits in brown seeded genotypes of tef eragrostis tef zucc trotter
Agricultural and Food Science, 2015Co-Authors: Habte Jifar, Kebebew Assefa, Zerihun TadeleAbstract:Tef [Eragrostis tef (Zucc.) Trotter] is the major cereal crop of Ethiopia where it is annually cultivated on more than three million hectares of land by over six million small-scale farmers. It is broadly grouped into white and brown-seeded type depending on grain color, although some intermediate color grains also exist. Earlier breeding experiments focused on white-seeded tef, and a number of improved varieties were released to the Farming Community. Thirty-six brown-seeded tef genotypes were evaluated using a 6 × 6 simple lattice design at three locations in the central highlands of Ethiopia to assess the productivity, heritability, and association among major pheno-morphic traits. The mean square due to genotypes, locations, and genotype by locations were significant (P < 0.01) for all traits studied. Genotypic and phenotypic coefficients of variations ranged from 2.5 to 20.3 % and from 4.3 to 21.7 %, respectively. Grain yield showed significant (P < 0.01) genotypic correlation with shoot biomass and harvest index, while it had highly significant (P < 0.01) phenotypic correlation with all the traits evaluated. Besides, association of lodging index with biomass and grain yield was negative and significant at phenotypic level while it was not significant at genotypic level. Cluster analysis grouped the 36 test genotypes into seven distinct classes. Furthermore, the first three principal components with eigenvalues greater than unity extracted 78.3 % of the total variation. The current study, generally, revealed the identification of genotypes with superior grain yield and other desirable traits for further evaluation and eventual release to the Farming Community.
