Grilling and frying heart muscles resulted in the highest Ca (45.9 mg/kg) and Mg (98.9 mg/kg), whereas boiling led to the lowest Ca (41.1 mg/kg) and Mg (91.4 mg/kg) concentration. The highest concentrations of Fe and Zn these minerals were recorded in grilled (32.7 mg/kg) and fried samples (75.2 mg/kg). Zinc and Fe concentration observed in liver and heart muscles were higher than those found in breast and leg muscle. In conclusion, the results confirm the potential of MOLP for use as an alternative to antibiotics in maintaining broiler health, reducing mortalities and improving carcass characteristics and some meat quality traits.]]> Wed 12 May 2021 14:33:22 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40061 Wed 12 May 2021 14:25:46 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40728 Wed 12 May 2021 14:08:57 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:16162 Tue 07 May 2024 11:18:30 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11860 Thu 13 May 2021 06:38:28 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:3535 Thu 13 May 2021 06:36:18 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:5796 Thu 13 May 2021 06:35:55 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:2160 Thu 13 May 2021 06:31:46 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:4664 Thu 13 May 2021 05:18:30 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:5321 Thu 13 May 2021 03:56:56 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:5777 Thu 13 May 2021 03:52:46 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:3335 Thu 13 May 2021 03:52:41 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:28324 37 percent); though it was reduced (26.9±2.64 percent) on days with higher temperatures and low humidity. 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 ]]>
