Variation in village chicken production systems among agro-ecological zones of Zimbabwe

Abstract: The degree to which village chickens are integrated in the smallholder farming systems differs depending on the socio-economic, cultural and biological factors within each system. The objective of this study was to characterise the village chicken farming systems and identify possible threats to, and opportunities for, local chickens in the agro-ecological zones of Zimbabwe. A pre-tested questionnaire was administered to households randomly selected from five districts, Risitu (n = 97), Hurungwe (n = 56), Gutu (n = 77), Gokwe-South (n = 104) and Beitbridge (n = 37) in eco-zones I–V, respectively. Age of head of household averaged 47 years (SD = 14.3). Land holdings per household averaged 4.82 ha (SD = 3.6). Overall, 17.7 percent of the households ranked livestock as the major source of income compared to 70.8 percent who ranked crops as the main contributor. Chicken flock size averaged 16.7 (SD = 12.4), and the highest flock sizes were observed in eco-zones I and IV. Households owning cattle, goats and other livestock assigned less important ranks to chickens. Chickens were used mainly for the provision of meat and eggs whilst the use of chicken feathers and investment were uncommon practises. Results indicate that more support is necessary for village chickens in the non-cropping regions of the country.

Evaluation of Intussusception after Monovalent Rotavirus Vaccination in Africa

Abstract: Background Postlicensure evaluations have identified an association between rotavirus vaccination and intussusception in several high- and middle-income countries. We assessed the association between monovalent human rotavirus vaccine and intussusception in lower-income sub-Saharan African countries. Methods Using active surveillance, we enrolled patients from seven countries (Ethiopia, Ghana, Kenya, Malawi, Tanzania, Zambia, and Zimbabwe) who had intussusception that met international (Brighton Collaboration level 1) criteria. Rotavirus vaccination status was confirmed by review of the vaccine card or clinic records. The risk of intussusception within 1 to 7 days and 8 to 21 days after vaccination among infants 28 to 245 days of age was assessed by means of the self-controlled case-series method. Results Data on 717 infants who had intussusception and confirmed vaccination status were analyzed. One case occurred in the 1 to 7 days after dose 1, and 6 cases occurred in the 8 to 21 days after dose...

Exploring the Self-Concept in an African Culture

Abstract: Self-concept orientations (individualistic, collectivistic, and moralistic) were examined for 210 Zimbabwe college students of a Shona cultural background. Although the students tended to endorse an individualistic self-concept orientation to a significant extent, the women and the older students were more inclined to perceive of the self-concept as collectivistic and moralistic in orientation. Implications for self-concept models for African cultures and suggestions for further research are discussed.

Monogeneans of the genus Cichlidogyrus Paperna, 1960 (Dactylogyridae: Ancyrocephalinae) from cichlid fishes of Lake Kariba (Zimbabwe) with descriptions of five new species

Abstract: The gills of six species of cichlid present in Lake Kariba (Zimbabwe) revealed the presence of twelve species of Cichlidogyrus, five being new species. The parasites were as follows: C. halli (Price & Kirk, 1967) in Oreochromis mortimeri (main host) and Serranochromis macrocephalus (occasional host); C. tilapiae Paperna, 1960 and C. longicornis Paperna & Thurston, 1969 in O. mortimeri only; C. sclerosus Paperna & Thurston, 1969 in O. mortimeri (main host) and in S. macrocephalus (occasional host); C. haplochromii Paperna & Thurston, 1969 in Pharyngochromis darlingi only; C. tiberianus Paperna, 1960 in Tilapia rendalli only; C. dossoui n. sp. in T. rendalli (type-host) and in O. mortimeri and S. macrocephalus (occasional hosts); C. karibae n. sp. in S. codringtonii (type-host) and in O. mortimeri (occasional host); C. zambezensis n. sp. in S. macrocephalus (type-host) and in O. mortimeri (occasional host); C. quaestio n. sp. in T. rendalli (type-host) and in S. codringtonii and S. macrocephalus (occasional hosts); C. philander n. sp. in Pseudocrenilabrus philander. C. longicornis gravivaginus Paperna & Thurston, 1969, found in O. mortimeri, is elevated to specific status.
