Meat colour attributes (L* a* b* and C*) were influenced by diet, with 20% cactus diet having lower L* values compared to other diets (P ≤ 0.05). During a 14-day retail display, a diet  day interaction was observed for hue angle with the cactus diets having the lowest values at day 14 of display compared to the other diets (P ≤ 0.05). Differences in meat from heifers fed different diets were observed with 20% cactus accounting for significantly (P ≤ 0.05) higher levels of deoxymyoglobin and the lowest levels of oxymyoglobin. Thawing loss and Warner Bratzler shear force decreased (P ≤ 0.05) with ageing period. Meat from heifers fed cactus diets had lower (P ≤ 0.05) proportions of oleic acid (C18:1n9c) and total MUFA, higher (P ≤ 0.05) proportions of total SFA, C15:1, C17:1, linoleic acid (C18:2n6c) and total PUFA. The control diet produced meat with the highest thiobarbituric acid reactive substances (TBARS) values compared to other diets (P ≤ 0.05) and with ageing TBARS values increased (P ≤ 0.05). Diet showed an effect (P ≤ 0.05) on sensory attributes such as overall tenderness and mouth feel with cactus diets accounting for lower scores. However, juiciness, overall tenderness, grassy and animal like attributes increased with ageing (P ≤ 0.05). Inclusion of cactus in the diet did not produce any adverse effects on meat quality, fatty acid composition, lipid oxidation and sensory quality. Therefore, it can be concluded that inclusion of cactus in Nguni heifer finisher diets up to 20% can improve meat quality.]]> Wed 12 May 2021 14:16:18 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:28073 Thu 13 May 2021 06:40:18 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:39264 Thu 13 May 2021 01:26:21 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:39121 0.05) difference in forage dry matter (DM) among the herbicide treatments in both years at Kubedlana. Results further showed that all five herbicides did not significantly (p > 0.05) increase the DM yield over control treatment. At Sinqumeni, results displayed no significant (p > 0.05) difference in forage DM among treatments during year 1, whereas in year 2, but all herbicide treatments except Haloxyfop-R methyl & Bendioxide (HBE) yielded greater (p < 0.05) DM yield than the control treatment. Comparing years, forage DM yield only under Bendioxide (BEN) and Paraquat (PAR) treatments had greater DM yield in year 2 than years 1. In Kubedlana, Bendioxide (BEN) and Haloxyfop-R methyl (HAL) treatments showed an IV increase in total density (TD), whereas Glyphosate (GLY) produced the lowest total density (TD) and Paraquat (PAR) and Haloxyfop-R methyl (HAL) resulted in an increased in density of total legumes (TL) relative to control treatment. There was a decline (p < 0.05) in the densities of total plants and forbs from year 1 to year 2. In Sinqumeni, herbicide applications resulted in higher density of total legumes than the control treatment, but results varied among herbicide treatments, greatest density being obtained at Haloxyfop-R methyl & Bendioxide (HBE) and Haloxyfop-R methyl (HAL) treatments. On phosphorus study, result showed a significant (p < 0.05) differences in dry matter (DM) yield among Phosphorus (P) treatments during year 2 of the study at Kubedlana site. All P treatments showed significantly greater dry matter (DM) yield in forage harvested in year 2 compared to year 1. At Sinqumeni, results showed Phosphorus (P) application did not have significance (p > 0.05) effect on forage dry matter (DM) yield on both years. In Kubedlana, there were indications of increased densities of total grasses, legumes and total plants in response to some levels of phosphorus (P) treatments. Treatment Phosphorus at 20 kg ha-1 (P20) yielded the highest total density (TD) and total legumes (TL) numbers and P10 had the lowest total density (TD). Both treatment and year interacted significantly (p < 0.05) to influence the mean density of some plant variables. At Sinqumeni, there were no significant differences due to phosphorus (P) treatments in the densities of total plants, grasses and forbs. Both years interacted significantly (p < 0.05) with treatments to influence the plant density mean, with Lespedeza cuneate (LESP) producing the highest plant density during year 1 and year 2, whereas BSERRL produced the lowest plant density during year 1 and year 2 periods. Therefore, findings of this study suggest that application of both Bendioxide (BEN) & Haloxyfop-R methyl & Bendioxide (HBE) treatments result in a decrease in dry matter (DM) yield, whereas Glyphosate (GLY) herbicide resulted in a decrease in both total density (TD) and total legumes (TL) and Haloxyfop-R methyl (HAL) herbicide application resulted in an increase of total density (TD) and total legumes (TL) V relative to control plot. On phosphorus study, results suggest that at Phosphorus at 40 kg ha-1 (P40) fertilization dry matter (DM) yield will be increased and at both Phosphorus at 20 kg ha1 (P20) and Phosphorus at 40 kg ha-1 (P40) high total density (TD) will be recorded where’s Phosphorus at 20 kg ha-1 (P20) fertilization result in high total legumes (TL).]]> Thu 13 May 2021 00:11:40 SAST ]]>
