There was a significant difference (P<0.05) in the heights of plants recorded by the varieties only at flowering stage. The yields of fresh biomass in C. cajan was significantly different (P<0.05) across all the varieties harvested in 2016. In all the varieties there was a significant difference (P<0.05) in dry matter yield in both seasons of 2016 and 2017. The effect of browse varieties and drying methods showed a significant effect (P<0.05) on DM, CP, fat, NDIN, ADIN and hemicellulose content of varieties. There was little impact by varieties and drying methods (P<0.05) on ash, NDF, ADF, ADL, TNC and cellulose content of varieties. Varieties and drying method had no effect (P>0.05) on Ca, Mg and K except for Na and P. There was no effect caused by varieties and drying methods (P>0.05) on Zn and Mn with Cu and Fe being the exceptions. Oven drying showed an overall reduction in the tannin concentration on leaves while there was an increase in saponins. The different varieties had no effect (P>0.05) on the IIR, 0.0275±0.0089, 0.0275±0.0077 and 0.0409±0.0109 for Cv1, Cv2 and Cv3, respectively. The day of the trial and browse variety had an effect (P<0.05) on bite rate. However, the day of trial had no significant effect (P>0.05) on both bite size and the instantaneous intake rate. Individual goat had a significant effect (P<0.05) on bite rate. There was a significant difference (P<0.05) in the in vitro and in sacco rapidly degradable fractions (a) of all the three varieties but the drying method had no effect (P>0.05). The slowly degradable fraction (b) and degradation rate constant (c) of all varieties was not significantly different (P>0.05) on both drying methods during IV DaisyII procedure. However, b and c, in all the varieties was significantly different (P<0.05) in both drying methods during the in sacco procedure. There was no significant difference (P>0.05) in the mean potentially degradable fraction (a+b) across all C. cajan varieties during IV DaisyII procedure, however a+c of all varieties was significantly different (P<0.05) in both the drying methods during the in sacco procedure. The effective in vitro and in sacco degradability of the varieties was significantly different (P<0.05) with a rumen outflow rate of 2, 5 and 8 percent per hour. The shade-dried varieties had a higher (P<0.05) ED than the oven-dried materials during IV DaisyII and the in sacco procedures. It was concluded that the decline in yield of C. cajan during the study is a reflection of poor survival, the insufficient regeneration from seed, nutrient depletion over time and the extended dry seasons. Therefore, shade drying is commended method of drying forages.]]> Wed 12 May 2021 17:44:45 SAST ]]> Student-teachers' perspectives of the role of environmental education in geography education https://vital.seals.ac.za/vital/access/manager/Repository/vital:1776 Wed 12 May 2021 17:21:57 SAST ]]> Exit strategies in social protection and the role of the social worker : a case study of exited households from the harmonised social cash transfers in Goromonzi District, Zimbabwe https://vital.seals.ac.za/vital/access/manager/Repository/vital:32389 Wed 12 May 2021 16:17:23 SAST ]]> The Karoo caterpillar Loxostege Frustalis Zeller (Lepidoptera : Pyralidae) in relation to its host plants and natural enemies https://vital.seals.ac.za/vital/access/manager/Repository/vital:5604 Wed 12 May 2021 15:52:45 SAST ]]> Drought management strategies and poverty alleviation in Zimbabwe : the case of Mwenezi District https://vital.seals.ac.za/vital/access/manager/Repository/vital:40663 Wed 12 May 2021 14:11:45 SAST ]]> Nutritional and pharmacological profile of moringa oleifera lam.

There exists a good agreement between WC and WHR. Also, a moderate agreement exists between WC and WHtR, WC and NC, WHR and WHtR, and WHtR and NC. The prevalence of above normal body composition for participants with hypertension was 71.0 percent, 65.9 percent, 63.2 percent and 66.5 percent by WC, WHR, WHtR and NC, respectively. For diabetes, the prevalence was 20.6 percent, 19.4 percent, 17.0 percent and 18.6 percent by WC, WHR, WHtR and NC, respectively. Waist circumference was a stronger predictor of hypertension and diabetics, with odds ratio of 3.7 (95 percent CI: 2.3-6.1 and 3.1 (95 percent CI: 1.6-6.0), compared to NC, with odds ratio of 1.7 (95 percent CI: 1.1-2.8). The prevalence of pre-hypertension was 33.7 percent and hypertension was 57.0 percent. Age, marital status, level of education, period of driving, obesity, alcohol, sweet drinks consumption and diabetes were significantly associated with hypertension. After adjusting for confounders, age >35 years (P=0.004), obesity and alcohol use (P<0.001), period of driving >5years (p=0.028) and diabetes (P=0.003) were significant predictors of hypertension. Prevalence of pre-diabetes and diabetes was 17 percent and 16 percent, respectively. Of those who were diabetic (n=63), the majority were aware of their diabetes status (n=43) and were on treatment (n=30). Age, marital status, level of education, period of driving, obesity, sweet drinks consumption, physical activities and hypertension were significantly associated with diabetes. Only age >35 (AOR= 3.6, CI 1.2-11.1), ever married (AOR= 3.3, CI 1.5-7.0) and hypertension (AOR= 3.4, CI 1.7-6.8) were the independent predictors of diabetes after adjusting for confounders. The prevalence of metabolic syndrome was 22 percent. Age, marital status, level of education, physical inactivity and period of driving were significantly associated with metabolic syndrome. After adjusting for confounders, only age above 35 years (Adjusted Odd Ratio [AOR] =3.8, CI=1.4- 9.5), ever married (AOR=3.0, CI=1.6-5.3) and period of driving above five years (AOR= 2.4, CI=1.2-4.7) were the significant and independent predictors of metabolic syndrome. About 30 percent of the participants were daily smokers, 37 percent consume alcohol regularly and only 18 percent were physically active, while 82 percent were physically inactive. In conclusion, there was a high prevalence of obesity, hypertension and diabetes among the commercial drivers in this setting, which is associated with unhealthy lifestyles (smoking, excessive alcohol consumption, physical inactivity). Interventions aimed at promoting cardiovascular health of commercial drivers such as health education and workplace screening, should prioritize weight reduction, healthy eating and physical activity in this population.]]> Thu 13 May 2021 00:20:29 SAST ]]> A framework for digital signature implementations for e-government services https://vital.seals.ac.za/vital/access/manager/Repository/vital:39490 Thu 13 May 2021 00:07:49 SAST ]]> Intertidal patterns and processes : tracking the effects of coastline topography and settlement choice across life stages of the mussels perna perna and mytilus galloprovincialis https://vital.seals.ac.za/vital/access/manager/Repository/vital:5721 Fri 14 Jan 2022 10:57:18 SAST ]]>
