During processing and storage, TBARS were higher (P < 0.05) in pork droëwors (maximum 3.83 mg MDA/kg DM) than in beef (maximum 0.99 mg MDA/kg DM). Moringa oleifera leaf powder contained high levels of TPC (7.5 ± 0.2 mg gallic acid eq/g) and substantial levels of α-tocopherol (76.7 ± 1.9 mg/100 g) and β-carotene (23.2 ± 2.8 mg/100 g). The FRAP, α-tocopherol and β-carotene content of pork droëwors increased (P < 0.05) proportionally with increasing levels of MLP inclusion. Lipid oxidation occurred more rapidly (P < 0.05) when MLP was not added and was similar (P > 0.05) for all MLP treatments. There was no significant effect of the inclusion of 0.75 g/100 g MLP on the drying curves and physico-chemical characteristics of the droëwors. The α-tocopherol content was higher (P < 0.05) and TBARS during storage were lower (P > 0.05) with MLP addition. The results of the current study give an overview of the composition of commercial droëwors and showed higher susceptibility to lipid oxidation in pork droëwors. Moringa oleifera leaf powder exhibited antioxidant activity in pork droëwors, inhibited lipid oxidation and increased the content of α-tocopherol in the product. It can be concluded that MLP could be used as a functional antioxidant additive in pork droëwors.]]> Tue 07 May 2024 11:01:32 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:5389 Thu 29 Sep 2022 14:19:59 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:19994 Thu 13 May 2021 14:49:35 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:19962 Thu 13 May 2021 13:24:49 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:20677 Thu 13 May 2021 13:21:29 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:4565 Thu 13 May 2021 12:41:15 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:28423 Thu 13 May 2021 10:40:07 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:4560 Thu 13 May 2021 08:53:23 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:2332 Thu 13 May 2021 08:51:21 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:1335 Thu 13 May 2021 08:46:52 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:2064 Thu 13 May 2021 08:23:10 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:27888 Thu 13 May 2021 08:19:50 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:30708 Thu 13 May 2021 08:08:13 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:26960 Thu 13 May 2021 07:38:12 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:24530 Thu 13 May 2021 07:35:57 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:3553 Thu 13 May 2021 07:35:29 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:26968 _D 2 suffciently large, a non-constant positive solution is generated, that is, stationary patterns emerge, depicting dispersal of species.

Fatty acid analysis revealed evidence for trophic transfer of specific fatty acids from basal resources to waterbirds in the Kowie Estuary but provided little information on seasonal diet of waterbirds. Waterbirds foraging in the Kowie Estuary appeared to shift their diet to coincide with resource abundance pulses, but also displayed seasonal dietary overlap.

Higher proportions of drinking (1.5±1.04 percent) and standing (20.8±4.63 percent) behaviours prolonged in such weather conditions, which were mostly during midday. The avoidance-related behaviour of the steers during handling varies, with the steers showing more avoidance and aggression in other weeks than some. These variations could however be traced back to the events of that particular day/time of handling. Only Weighing Box (WBS) and stepping (SS) scores differed (P<0.05) with genotype; with more calm NG steers (> 40 percent) and not kicking than the ND steers that were more vocal (20–60 percent) and kicking (> 5 percent). In addition, the weekly behavioural responses were reflected (P<0.05) in the measured cortisol, glucose and lactate. However, regardless of the prominent negative behaviour seen over time, the levels of the measured blood constituents continued to drop. Furthermore, steers of different genotypes displayed similar (P>0.05) response to the identical pre-slaughter conditions they were exposed to. However, steers that were Transport Group 1 (TG1) showed more avoidance (63.2 percent) pre-slaughter than those in TG2 (23.9 percent). Furthermore, all the steers that were in slaughter Group 2 (SG2) showed less avoidance behaviour than those in other groups. Vocalization was observed only for ND steers (5 percent), in TG1 and SG2. Some connections between the observed pre-slaughter activities and some behavioural and physiological changes of these steers were established; with TG1 and SG1 steers showing higher cortisol (140±14.50 and 175.9±17.24 nmol/L, respectively) and lactate (12.4±0.83 and 13.5±1.12 mmolL) levels than the other groups. Lastly, the muscle type, genotype, lairage duration, slaughter order and stress responsiveness have an effect on some meat quality characteristics of the two genotypes; with the L. dorsi muscle having highest WBSF (38.0±1.35N) than the Superficial pectoral muscle (Brisket muscle) (30.7±1.35N). Additionally, steers lairaged for a shorter time produced a L. dorsi with higher WBSF (41.6±2.34N) and a Brisket with lower TL (2.7±0.24 percent). It can therefore be concluded that the conditions and activities at the farm, during transportation, lairaging and slaughter at the abattoir have an influence on some behavioural and physiological changes and the quality of beef harvested from the Nguni and non-descript steers that were extensively-reared in natural pastures. However, the relationship patterns between these different conditions are not clear.]]> Thu 13 May 2021 03:34:22 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:28629 Thu 13 May 2021 03:31:37 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:4564 Thu 13 May 2021 03:19:45 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:21162 Thu 13 May 2021 03:15:07 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:27792 Thu 13 May 2021 03:05:05 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:28074 Thu 13 May 2021 02:52:02 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:20806 Thu 13 May 2021 02:38:45 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:21319 Thu 13 May 2021 02:33:43 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:25341 Thu 13 May 2021 02:30:55 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:20001 Thu 13 May 2021 02:00:39 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:27106 Thu 13 May 2021 02:00:28 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:5385 Thu 13 May 2021 01:52:29 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:26565 Thu 13 May 2021 01:45:19 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:19977 Thu 13 May 2021 01:35:24 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:1336 Thu 13 May 2021 01:09:53 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:27003 Thu 13 May 2021 01:01:58 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:2069 Thu 13 May 2021 00:57:25 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:20845 Thu 13 May 2021 00:37:58 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:27157 Thu 13 May 2021 00:30:30 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:27750 Thu 13 May 2021 00:25:22 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:3407 Thu 13 May 2021 00:12:47 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:19968 Thu 13 May 2021 00:12:41 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:19984 Thu 13 May 2021 00:01:07 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:27002 Thu 13 May 2021 00:01:03 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:20005 Thu 13 Jul 2023 12:28:07 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:19965 Sat 09 Sep 2023 09:32:33 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:27054 Fri 15 Mar 2024 12:04:29 SAST ]]> http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:19947 Fri 06 Aug 2021 11:40:35 SAST ]]>
