Lipid oxidation occurred more rapidly (P<0.05) when MLM was not added. During processing and storage, TBARS were higher (P< 0.05) in chicken droewors. TBARS during storage were lower (P>0.05) with MLM added. Results showed a significant difference (P<0.05) in proximate composition of chicken droëwors, containing on average 16.93±1.29 to 10.79± 1.83/ 100 g moisture, 45.80± 1.65 to 67.56± 2.33/ 100 g protein, 14.37± 2.15 to 26.13± 2.15/100 g ash. The current study resultsgave a summary of the composition of chicken droëwors and showed higher susceptibility to lipid oxidation in chicken droewors. Therefore, Moringa oleifera leaf powder showed antioxidant activity in chicken droëwors, reserved lipid oxidation in the product. In conclusion, MLM could be used as a functional antioxidant preservative in chicken droëwors.]]> Wed 16 Feb 2022 11:50:07 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:42948 Wed 12 May 2021 15:07:02 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:42809 Wed 12 May 2021 14:49:21 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:42934 0.5). The model also performed generally well compared to established models that had been previously applied in some of the study catchments. The highest sediment yields recorded per country were 153 t km-2 year-1 (Tsitsa River; South Africa), 90 t km-2 year-1 (Odzi River; Zimbabwe) and 340 t km-2 year-1 (Rio Tanama; Puerto Rico). The results also displayed consistent underestimations of peak sediment yield events, partly attributed to sediment emanating from gullies that are not explicitly accounted for in the WQSED model structure. Furthermore, the calibration process revealed that the WQSED storage model is generally challenging to calibrate. An alternative simpler version of the storage model was easier to calibrate, but the model may still be challenging to apply to catchments where calibration data are not available. The additional evaluation of the WQSED simulated sediment yield rates against observed reservoir sediment rates showed a broad range of differences between the simulated and observed sediment yield rates. Differences between WQSED simulated sediment and observed reservoir sediment ranges from a low of 30% to a high of > 40 times. The large differences were partly attributed to WQSED being limited to simulating suspended sediment from sheet and rill processes, whereas reservoir sediment is generated from more sources that include bedload, channel and gully processes. Nevertheless, the model simulations replicated some of the regional sediment yield patterns and are assumed to represent sheet and rill contributions to reservoir sediment in selected catchments. The outcome of this study is an improved WQSED model that has successfully undergone preliminary testing and evaluation. Therefore, the model is sufficiently complete to be used by independent researchers and water resources managers to simulate erosion and sediment transport. However, the model is best applicable to areas where some observed data or regional information are available to calibrate the storage components and constrain model outputs. The report on potential MUSLE scale dependencies is relevant globally to all studies applying the MUSLE model and, therefore, can improve MUSLE application in future studies. The WQSED model offers a relatively simple, effective and applicable tool that is set to provide information to enhance catchment, land and water resources management in catchments of Africa.]]> Wed 12 May 2021 14:47:01 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:42897 Wed 12 May 2021 13:50:47 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:42943 Wed 12 May 2021 13:47:23 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:42951 Wed 12 May 2021 13:46:56 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:42939 Wed 12 Jul 2023 08:28:50 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:42920 Tue 25 May 2021 11:08:42 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:48621 0.05) between the cultivars. The number of tillers were significantly different (P<0.05), the highest number of tillers was observed in Mombaca. Fresh yield showed significant differences at 10 and 14WAP, with Marandu producing the highest Fresh yield. The moisture content was different (P<0.05) across all the three harvests. Varying (P< 0.05) results were also observed in the dry matter yield of the cultivars with Mombaca producing the highest dry matter yield. There were no significant differences (P>0.05) in the ash content of the cultivars. The fat content also showed no significant differences. Variations (P<0.05) occured in the ADF of the cultivars, Marandu had the lowest ADF. The cultivar × WAP interactive effect was significant for ADL content. NDF significantly varied across the cultivars at 6WAP. There were no similarities (P<0.05) in the crude protein during the three harvesting intervals, Mombaca produced the highest CP and the lowest was obtained from Gatton. There was a significant interaction (P<0.05) between the cultivars and harvesting intervals for Calcium (Ca), Magnesium (Mg), Sodium (Na), Potassium (K), K/Ca+Mg, Copper (Cu), Iron (Fe), Zinc (Zn) and Manganese (Mn) contents of the cultivars. However, Phosphorus (P) showed no significant interaction (P>0.05) between the cultivars and harvesting intervals. The results obtained in this study showed that as the grasses grow, the biomass yield produced increases according to the genetic makeup and the factors affecting growth and biomass yield. However, the chemical composition decreased between cultivars. Mombaca showed superior traits in terms of growth biomass yield and chemical composition. Mombaca, which is a Panicum maximum cultivar can be used as a choice in forage production and chemical composition as it can supply both quality and quantity. It can be concluded that there are significant differences in growth characteristics, biomass yield and chemical composition of Panicum maximum and Brachiaria brizantha cultivars at different harvesting stages. It can also be recommended that the best harvesting stage is at 10 WAP, this is because both biomass yield and chemical composition are both satisfactory.]]> Tue 22 Mar 2022 11:50:45 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:42891 Tue 14 Feb 2023 07:55:10 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:45637 Tue 11 Jan 2022 11:14:29 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:42776 Thu 27 May 2021 15:12:47 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:42921 Thu 20 May 2021 16:09:53 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:42932 Thu 20 May 2021 09:23:52 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:53179 Thu 14 Jul 2022 10:21:34 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:47201 Thu 07 Mar 2024 14:36:28 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:66243 Thu 03 Aug 2023 13:41:01 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:46554 Mon 14 Feb 2022 13:03:18 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:45207 Fri 18 Feb 2022 15:47:53 SAST ]]>
