Abstract Identification of breeding practices and traits preferences by farmers for selection of breeding animals to be parents of the next generations is the crucial step to the successful implementation of community-based breeding programs (CBBPs). The aim of the study was to detect breeding practices and traits preferences by farmers at Lepelle-Nkumpi Local Municipality, South Africa to determine their relevance in establishing a CBBPs. A structural questionnaire was designed and administered to 183 randomly selected goat keepers from 4 villages. Across the 4 communities, the majority of goat keepers were males with the traditional purposes, sales and meat production as their main reasons of keeping goats. Spring breeding season was practiced using natural mating system controlled mainly by means of castration and culling of poor reproductive or undesired goats for breeding. The most important common farmers’ preference traits among the four communities were twining ability, good mothering ability and body size in breeding does, and mating ability, growth rate and body size in breeding bucks. However, the selection of breeding stock might also include qualitative traits such as coat color of goats. The results from this study are useful for designing CBBPs for indigenous goats in Lepelle-Nkumpi Local Municipality.

ABSTRACTIt has been recognized that the Merle coat pattern is not only a visually interesting feature, but it also exerts an important biological role, in terms of hearing and vision impairments. In 2006, the Merle (M) locus was mapped to the SILV gene with a SINE element in it, and the inserted retroelement was proven causative to the Merle phenotype. Mapping of the M locus was a genetic breakthrough and many breeders started implementing SILV SINE testing in their breeding programs. Unfortunately, the situation turned out complicated as genotypes of Merle tested individuals did not always correspond to expected phenotypes, sometimes with undesired health consequences in offspring. Two variants of SILV SINE, allelic to the wild type sequence, have been described so far - Mc and M.Here we report a significantly larger portfolio of existing Merle alleles (Mc, Mc+, Ma, Ma+, M, Mh) in Merle dogs, which are associated with unique coat color features and stratified health impairment risk. The refinement of allelic identification was made possible by systematic, detailed observation of Merle phenotypes in a cohort of 181 dogs from known Merle breeds, by many breeders worldwide, and the use of advanced molecular technology enabling the discrimination of individual Merle alleles with significantly higher precision than previously available.We also show that mosaicism of Merle alleles is an unexpectedly frequent phenomenon, which was identified in 30 out of 181 (16.6%). dogs in our study group. Importantly, not only major alleles, but also minor Merle alleles can be inherited by the offspring. Thus, mosaic findings cannot be neglected and must be reported to the breeder in their whole extent.In light of negative health consequences that may be attributed to certain Merle breeding strategies, we strongly advocate implementation of the refined Merle allele testing for all dogs of Merle breeds to help the breeders in selection of suitable mating partners and production of healthy offspring.

Community Based Education

Education of health professionals using principles of community-based education is the recommended national policy in South Africa. A paradigm shift to community based education is reported in a number of nursing education institutions in South Africa. Reviewed literature however revealed that in some educational institutions planning, implementation and evaluation of Community-based Educational (CBE) programmes tended to be haphazard, uncoordinated and ineffective, resulting in poor student motivation. Therefore the purpose of this study was to analyse the implementation of community-based education in basic nursing education programmes in South Africa. Strauss and Corbin’s (1990) grounded theory approach guided the research process. Data were collected by means of observation, interviews and document analysis. The findings revealed that collaborative decision-making involving all stakeholders was crucial especially during the curriculum planning phase. Furthermore, special criteria should be used when selecting community learning sites to ensure that the selected sites are able to facilitate the development of required graduate competencies. Collaborative effort, true partnership between academic institutions and communities, as well as government support and involvement emerged as necessary conditions for the successful implementation of community-based education programmes.

Intervention Service

Infants and toddlers with special needs within the developing context in South Africa are not currently receiving adequate early communication intervention services. The development of a model for service delivery to this population is imperative for the successful implementation of early communication intervention in the developing context in South Africa. The basic model of early intervention service delivery provides a theoretical basis for early intervention service delivery but has certain limitations when applied to the developing context in South Africa. Community-based intervention is proposed as an avenue for the delivery of health care services within primary health care although constraints in the application of community-based intervention exist. An integrated model of early communication intervention service delivery within community-based intervention is proposed and illustrated by presenting a case example.

Cycads are the most threatened group of plants in the world and there are a wide range of ecological and anthropological forces responsible for the extinction risk of these taxa. South Africa is a global hotspot of cycad diversity and the country’s cycads are facing high extinction risk. In this study we sampled a population (n=34) of Encephalartos transvenosus Stapf & Burtt Davy, a cycad species endemic to Limpopo Province, South Africa. The population was located on the Soutpansberg mountain range in the Mutale local municipality. A survey was conducted to quantify the threats to the population.  Forty-seven percent of the plants had been damaged by bark harvesting for traditional medicine, and the population showed a mortality rate of 9%. We recommend further studies at a range of Encephalartos transvenosus populations to provide a broader understanding of impacts of harvesting and population trends. We also recommend community based initiatives to enhance the protection of this species in the communities in which they are found.

Stephanus Le Roux Marais (1896−1979) lived in Graaff-Reinet, South Africa, for nearly a quarter of a century. He taught music at the local secondary school, composed most of his extended output of Afrikaans art songs, and painted a number of small landscapes in the garden of his small house, nestled in the bend of the Sunday’s River. Marais’s music earned him a position of cultural significance in the decades of Afrikaner dominance of South Africa. His best-known songs (“Heimwee,” “Kom dans, Klaradyn,” and “Oktobermaand”) earned him the local appellation of “the Afrikaans Schubert” and were famously sung all over the world by the soprano Mimi Coertse. The role his ouevre played in the construction of a so-called European culture in Africa is uncontested. Yet surprisingly little attention has been paid to the rich evocations of landscape encountered in Marais’s work. Contextualized by a selection of Marais’s paintings, this article glosses the index of landscape in this body of cultural production. The prevalence of landscape in Marais’s work and the range of its expression contribute novel perspectives to understanding colonial constructions of the twentieth-century South African landscape. Like the vast, empty, and ancient landscape of the Karoo, where Marais lived during the last decades of his life, his music assumes specificity not through efforts to prioritize individual expression, but through the distinct absence of such efforts. Listening for landscape in Marais’s songs, one encounters the embrace of generic musical conventions as a condition for the construction of a particular national identity. Colonial white landscape, Marais’s work seems to suggest, is deprived of a compelling musical aesthetic by its very embrace and desired possession of that landscape.

Program pemuliaan ikan mas varietas Punten dilakukan dengan seleksi individu terhadap karakter bobot ikan. Pembentukan populasi dasar untuk kegiatan seleksi dilakukan dengan memijahkan secara massal induk ikan mas yang terdiri atas 20 induk betina dan 21 induk jantan yang dikoleksi dari daerah Punten, Kepanjen (delapan betina dan enam jantan), Kediri (tujuh betina dan 12 jantan), Sragen (27 betina dan 10 jantan), dan Blitar (15 betina dan 11 jantan). Larva umur 10 hari dipelihara selama empat bulan. Selanjutnya dilakukan penjarangan sebesar 50% dan benih dipelihara selama 14 bulan untuk dilakukan seleksi dengan panduan hasil sampling 250 ekor individu setiap populasi. Seleksi terhadap calon induk dilakukan saat umur 18 bulan pada populasi jantan dan betina secara terpisah dengan memilih berdasarkan 10% bobot ikan yang terbaik. Calon induk yang terseleksi kemudian dipelihara hingga matang gonad, kemudian dipilih sebanyak 150 pasang dan dipijahkan secara massal. Didapatkan respons positif dari hasil seleksi berdasarkan bobot ikan, yaitu 49,89 g atau 3,66% (populasi ikan jantan) dan 168,47 g atau 11,43% (populasi ikan betina). Nilai heritabilitas untuk bobot ikan adalah 0,238 (jantan) dan 0,505 (betina).Punten carp breeding programs were carried out by individual selection for body weight trait. The base population for selection activities were conducted by mass breeding of parent consisted of 20 female and 21 male collected from area Punten, eight female and six male (Kepanjen), seven female and 12 male (Kediri), 27 female and 10 male (Sragen), 15 female and 11 male (Blitar). Larvae 10 days old reared for four moths. Then after spacing out 50% of total harvest, the offspring reared for 14 months for selection activity based on the sampling of 250 individual each population. Selection of broodstock candidates performed since 18 months age on male and female populations separately by selecting based on 10% of fish with best body weight. Candidates selected broodstocks were then maintained until mature. In oder to produce the next generation 150 pairs were sets and held for mass spawning. The results revealed that selection response were positive, 49.89 g (3.66%) for male and 168.47 (11.43%) for female. Heritability for body weight is 0.238 (male) and 0.505 (female).
