Animal feeds on the Federation

An Occasional Paper on animal feed nutrition in the then Federation of Rhodesia & Nyasaland.A knowledge of the nutritive value of feeds is essential for correct and economical feeding of farm stock. In countries where the science of agriculture has been practised for a century or more a vast amount of data has accumulated and from this reliable values have been obtained for the animal feeds in use. In the tropics the study of animal nutrition is a relatively new subject and most of the information available about local feeding stuff's is based on chemical analysis. This is true in the Federation, although a few digestibility trials with animals have been carried out. It is well known that without digestibility data chemical analysis can only provide approximate values

The one minute mentor : a pilot study assessing medical students’ and residents’ professional behaviours through recordings of clinical preceptors’ immediate feedback

Introduction: The assessment of professional development and behaviour is an important issue in the training of medical students and physicians. Several methods have been developed for doing so. What is still needed is a method that combines assessment of actual behaviour in the workplace with timely feedback to learners. Goal: We describe the development, piloting and evaluation of a method for assessing professional behaviour using digital audio recordings of clinical supervisors’ brief feedback. We evaluate the inter-rater reliability, acceptability and feasibility of this approach. Methods: Six medical students in Year 5 and three GP registrars (residents) took part in this pilot project. Each had a personal digital assistant (PDA) and approached their clinical supervisors to give approximately one minute of verbal feedback on professionalism-related behaviours they had observed in the registrar’s clinical encounters. The comments, both in transcribed text format and audio, were scored by five evaluators for competence (the learner’s performance) and confidence (how confident the evaluator was that the comment clearly described an observed behaviour or attribute that was relevant). Students and evaluators were surveyed for feedback on the process. Results: Study evaluators rated 29 comments from supervisors in text and audio format. There was good inter-rater reliability (Cronbach α around 0.8) on competence scores. There was good agreement (paired t-test) between scores across supervisors for assessments of comments in both written and audio formats. Students found the method helpful in providing feedback on professionalism. Evaluators liked having a relatively objective approach for judging behaviours and attributes but found scoring audio comments to be time-consuming. Discussion: This method of assessing learners’ professional behaviour shows potential for providing both formative and summative assessment in a way that is feasible and acceptable to students and evaluators. Initial data shows good reliability but to be valid, training of clinical supervisors is necessary to help them provide useful comments based on defined behaviours and attributes of students. In addition, the validity of the scoring method remains to be confirmed

Chemical composition of three herbaceous tropical forage legumes grown successfully in Zimbabwe

A scientific study on animal- feed nutrition for better stock production in Zimbabwe.Desmodium uncinatum, Stylosanthes guianensis and Macroptilium atropurpureum, grown at the University of Zimbabwe Farm, were harvested serially in the early (December), mid (February) and late (April) growing season in 1992/93 and oven-dried. Field-cured hays were also made from the legumes in April 1993 and 1994. The legumes differed in phenological development which, in turn, influenced crude protein (CP) levels. The CP content of S. guianensis (132 to 167 g/kg dry matter) was the least and first rose and then fell, that of D. uncinatum (195 to 234 g/kg DM) decreased, while that of M. atropurpureum (189 to 229 g/kg DM) increased with the season. Neutral detergent fibre (NDF) was higher in the early (364 to 440 g/kg DM) than in the mid to late season (470 to 559 g/kg DM). S. guianensis was the most fibrous in April, while D. uncinatum contained the most lignin across the season (148 to 159 g/kg DM). The legumes, especially M. atropurpureum, were rich in calcium (9.8 to 20.4 g/kg DM) and phosphorus (1.8 to 3.3 g/kg DM). Hay making was associated with loss of quality (e.g., 14 to 31 percent less CP and 12 to 51 percent more NDF) that was attributable to leaf loss. D. uncinatum hay contained the most fibre, lignin and acid detergent insoluble nitrogen and the least minerals. It is concluded that, overall, M. atropurpureum was chemically the most nutritious legume

Cross-Linguistic Influence of Similar Phonological Contrasts for Heritage Bilingual Children in the United Kingdom

Children who grow up learning a heritage language at home, and a majority language from school and peers, represent a case of bilingualism in which there is less distinction between a “first” and “second” language. This thesis investigates the similar contrasts within two separate heritage language communities, in order to observe patterns that occur between heritage language groups. A contrast pairing for each pair of languages was chosen: one for English-Polish heritage bilingual children and one for English-Chinese children. It was hypothesized that there would be cross-linguistic influence present, and that the acoustic cues of the English contrast would influence the production and perception of the heritage language contrast. Children between ages 7;0 and 9;6 performed a picture-naming task and a perceptual categorisation task, involving a phonetic continuum across a lexical minimal pair. The data include heritage bilinguals as well as control samples of monolinguals of each language. Results suggest that the heritage bilinguals reliably produced and perceived each contrasts. A degree of cross-linguistic influence was also present, and was seen both spectrally and temporally. In production, a comparison of vowel duration between heritage speakers and monolingual English speakers showed a significant effect (p < 0.001), with heritage speakers relying less on the temporal cue. This was not repeated in perception. The effect is evaluated with respect to phonetic assimilation, presenting evidence for a shared phonetic space in which mutual influence occurs

Socio-economic aspects in draught animal-crop linkages: a diagnostic study of Tsholotsho, Chinyika and Mutoko smallholder farming areas of Zimbabwe

A research paper on Zimbabwe's small-holder farmers' constraints in crop production due to shortages of draught animal power during the 1994/95 agricultural season.A survey was conducted on 451 households in Tsholotsho, Chinyika and Mutoko smallholder areas to understand farmers’ crop production constraints in relation to draught animal power (DAP) during the 1994/95 agricultural season. Farmers without DAP constituted 48.6 percent in the three districts. Of these, 54.5 percent had access to neighbours’ or relatives’ animals. The rest hired or worked in others’ fields in exchange for draught animals. Animal diseases and shortage of grazing land were noted as the major constraints in animal production. Both farmer education and experience as well as household head were found to be associated with district (p<0.001). Tsholotsho had the largest number of farmers (52.8 percent) with more than 10 years experience while Mutoko had the largest proportion (43.3 percent) of Master farmers. Farmer education and experience were found to be independent of sex. The average land holdings per farmer for Tsholotsho, Chinyika and Mutoko were 6.21 ha, 4.22 ha and 1.62 ha, respectively. Tsholotsho is a dryland communal area whilst Chinyika is a relatively wet area. Mutoko is a typical communal area with a high population pressure. Maize is the main crop in Chinyika and Mutoko whilst millet is the most common in Tsholotsho
