  • The present study was carried out to compare the composition of major essential oil components in the flue-cured tobacco produced by Korea, America, China, Brazil and Zimbabwe. Above 100 essential oil components were separated by GC and major 18 components of them, known to be important contributors to flue-cured tobacco flavor and smoke taste, were identified by GC/MS. Neophytadiene was major in quantities in the oils mostly and its composition in flue-cured tobacco produced by Korea, America, Zimbabwe, Brazil, and Unnam and Yenji region of China was 26.82\%,\;25.17\%,\;26.50\%,\;16.92\%,\;and\;18.75\%\;and\;14.87\%$, respectively. Megastigmatrienone, one of the major tobacco carotenoid degradation products was contained above $10\%$ in the oils of flue-cured tobacco produced by Korea and America, but, it was comprised about $5.66\%$ to 8.00 in Brazil, Zimbabwe, and Unnam and Yenji region of China. Damascenone is important to the aroma of tobacco as a crotenoid degradation products. Its amount in the oils was $3.31\%\;in\;Brazil,\;3.13\%\;in\;America,\;2.57\%\;in\;Zimbabwe,\;2.54%$ in Yenji of China, $2.00\%$ in Korea and $1.85\%$ in Unnam of China. These results can furnish the basic information capable of evaluating the quality value of flue-cured tobacco produced by various nations.

  • The objective of this study was to determine the effect of draught stress on certain haemograms and ovarian activity and the influence of dietary supplementation on the negative effects of draught in cows. Blood parameters and ovarian activity were assessed in supplemented non-working (SNW), supplemented working (SW) and non-supplemented non-working (NSNW) cows. Body weights and body condition scores were recorded fortnightly. Blood samples were collected through jugular venipuncture in December, February and April to determine the contents of haematocrit, erythrocyte, haemoglobin and white blood cells. Ovarian palpations were carried out in October, January and April. The SW cows maintained body weights (p>0.05) during the monitoring period whereas both SNW and NSNW cows gained (p<0.05) body weights. Body condition scores were similar between SW and NSNW cows. Cows in the NSNW group had lower (p<0.05) haematocrit concentrations in April than both supplemented groups. In December, erythrocyte concentrations were similar (p>0.05) among all treatment groups. Haemoglobin concentrations were higher (p<0.05) in SW and SNW cows in February and April than in December. The SW cows had higher leucocyte contents (p<0.05) in February than the other groups of cows. All treatment groups showed similar (p>0.05) ovarian activity in January. However, the NSNW group showed a lower proportion (p<0.05) of cows that exhibited normal ovarian activity in April. The results suggest that dietary supplementation of cows increases haematocrit and haemoglobin contents. In addition, supplementary feeding during the period of draught power provision maintains ovarian activity in cows.

  • Genetic parameters were estimated for birth weight and weaning weight from three year (1991-1993) data totalling 1100 records of 25 rams to 205 ewes of Indigenous Sabi flock maintained at Grasslands Research Station in Zimbabwe. AIREML procedures were used fitting an Animal Model. The statistical model included the fixed effects of year of lambing, sex of lamb, birth type and the random effect of ewe. Weight of ewe when first joined with ram was included as a covariate. Direct heritability estimates of 0.27 and 0.38, and maternal heritability estimates of 0.24 and 0.09, were obtained for birth weight and weaning weight, respectively. The total heritability estimates were 0.69 and 0.77 for birth weight and weaning weight, respectively. Direct-aternal genetic correlations were high and positive. The corresponding genetic covariance estimates between direct and maternal effects were positive and low, 0.25 and 0.18 for birth weight and weaning weight, respectively. Responses to selection were 0.8 kg and 0.14 kg for birth weight and weaning weight, respectively. The estimated expected correlated response to selection for birth weight by directly selecting for weaning weight was 0.26. Direct heritabilities were moderate; as a result selection for any of these traits should be successful. Maternal heritabilities were low for weaning weight and should have less effect on selection response. Indirect selection can give lower response than direct selection.

  • The purpose of this paper is to carry out an empirical analysis of the link that exists between microfinance and poverty alleviation. The analysis is driven by literature searches on empirical works done by different researchers in different contexts. Qualitative research methodology was adopted, following a desktop approach. An empirical literature review took a centre stage in this investigation. An analysis of empirical works shows that microfinance enhances poverty alleviation despite the challenges such as the Indian Andhra Pradesh crisis. The paper is limited to a review of empirical sources of literature. A field survey, supported by an econometric analysis would have helped to generate robust results. This paper attempts to bring together the empirical works that were done in different contexts to shed light on the important relationship between microfinance and poverty. Many research works on microfinance depend upon personal anecdotes, thus this present paper attempts to compile the scattered empirical findings on microfinance and poverty alleviation.

  • A trial was conducted to evaluate the growth performance and carcass characteristics of LW ${\times}$ Mukota $F_1$ crosses when fed diets containing graded levels of maize cob meal. Sixteen LW ${\times}$ Mukota $F_1$ crossbred pigs of approximately 4.5 months of age, were randomly allocated to four diets that contained 0, 100, 200 and 300 g maize cobs/kg, which corresponded to 276.4, 360.3, 402.9 and 523.5 g NDF/kg, respectively. The pigs were fed ad libitum for 14 weeks. The diets were formulated to contain similar levels of energy (ca. 9MJ ME/kg) and protein (ca.160 g CP/kg). Average daily feed intake (ADFI), daily gain (ADG) and feed conversion ratio (FCR) were monitored for 14 weeks. At slaughter, the cold dressed weight (CDM) and backfat thickness (BFT) were determined. There was no significant linear relationship (p>0.05) between level of cob inclusion and ADFI. The ADG decreased as level of maize cobs increased (p<0.001). The pigs that were on 300 g cobs/kg had the highest FCR (p<0.05) as compared to pigs on the other three diets. No differences (p>0.05) were observed in the CDM between pigs that were fed diets that had 0 and 100 g maize cobs/kg. In addition, pigs on 100 and 200 g cobs/kg diets had the same CDM (p>0.05). The diet that contained 300 g cobs/kg gave the lowest (p< 0.001) CDM. Both BFT parameters showed a decrease (p<0.05) as level of maize cobs increased. An increase in CDM was associated with an increase in BFT (p<0.001), with the correlation coefficient between K7.5 and CDM being 0.84 (p<0.001). It can, therefore, be concluded that crossbred pigs perform well on diets containing up to 200 g/kg maize cobs.

  • This study made use of a qualitative approach with an intrinsic case study to explore how handheld devices applications were integrated in teaching and learning in Textiles, Clothing and Design programmes. Participants of the study were purposively sampled from the Textiles and Clothing department at a selected university of Science and Technology in Zimbabwe comprising eight lecturers and thirty-two students. In-depth, focus group interviews and observations were used to gather data for the study. The findings of the study showed that participants were still at the stage of actively experimenting with very limited handheld device applications for the purposes of teaching and learning. Photoediters and digital cameras were the commonest applications used in most modules of the Textiles, Clothing and Design programmes. Though the photoediters and digital cameras were found to match the multimedia category of the Functionality framework, these were not fully utilised by students. It was recommended that there is need for the Textiles, Clothing and Design lecturers to provide opportunities for students to use a variety of applications on handheld devices for collaborative designing in practical modules of the programmes as these can encourage the development of critical skills necessary for creating innovative textiles and fashion designs.
