The herbage height and basal cover had greater values (P<0.05) under rested plus chopping (CR) treatment followed by grazed plus chopping (GC). Grass biomass production and essential nutrients showed a greater concentration (P<0.05) under CR treatment than any treatments applied. The results on perceptions revealed that goats had the highest mean household holding number than any other livestock species across the selected villages in all the villages. Respondents indicated that both goats and cattle had equal or more importance than sheep. Three out of four villages raised cattle primarily for income generation and secondarily for cultural purposes like slaughtering during weddings ceremonies, amazila and also during woman circumcisions (Ntonjane). Similarly, goats and sheep were primarily raised for cash income generation. The results revealed that livestock population decreased over ten to twenty years (one-two decades) and poor rangeland condition is assumed to be the cause of the situation as feed is the key factor for production. The area was dominated by the grasses rather than by browse woody species so the above results are possible as the P. incana is more competitive than grasses. It was concluded that P. incana is detrimental to both rangeland and animal production. Forage and animal performance as well as farmers’ economic status (livelihoods) were negatively affected by P. incana invasion and the scientific assessment reported it to be detrimental to agriculture. Thus chopping and resting (CR) treatment resulted in a greater improvement of the basal cover, biomass production, soil nutrients as well as grass height than the other treatments applied. Therefore it can be concluded that chopping and resting the veld invaded with P. incana can improve the range and consequently animal production.]]> Wed 12 May 2021 23:41:51 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:39114 Wed 12 May 2021 23:40:41 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:28251 Wed 12 May 2021 23:40:05 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:27795 Wed 12 May 2021 23:26:17 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:39759 Wed 12 May 2021 23:19:15 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:28071 Wed 12 May 2021 23:18:19 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:29399 Wed 12 May 2021 23:06:47 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:28066 0.05) between Dense, Mixed and Moderate bushland. Woody plant density in all these sites exceed 2500 plants/ha, which showed that the rangeland was encroached with woody plants. Soil nutrient content was determined for each site. Five samples of soil were collected per site to test the effect of bush encroachment on soil nutrient composition. The concentration of nitrogen and soil pH increased with increase in bush density, while that of potassium, phosphorous, magnesium, sodium and sulphur showed no significant differences (P>0.05) across all homogenous vegetation units. The study revealed that Sheshegu communal farmers are aware of both negative and positive effects of encroachment on their community, and also argue that the government is not willing to support communal farmers in the process of reducing the spread of bush encroachment. It was concluded that the concentration of nitrogen and soil pH increased with increasing bush density and that bush encroachment had negative effects on herbaceous species. It was recommended that communal farmers should be formulating rangeland rules and regulations to manage rangeland resources. Rangeland rules and regulations should be based on the management of livestock management during grazing and harvesting of rangeland resources. The harvesting of woody and good timing of application of fire can also reduce the spread of bush encroachment. Veld resting and rotational grazing can also improve fuel load which is required for burning of woody plants. Furthermore, Department of agriculture should also provide workshops or training to communal farmers use different approaches or cheap ways of reducing bush encroachment and conserving rangeland resources.]]> Wed 12 May 2021 23:00:02 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:27672 Wed 12 May 2021 22:54:03 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:39627 0.05) in the concentration of OC, Ca, and Mg between the communities and seasons.

The mean soil pH recorded in this study was 5.4 implying the soils of Njwaxa and Mbizana communities were acidic. It is evident that communal farmers are well aware of their rangeland condition, changes occurring in their rangelands, their causes and are capable of suggesting some solutions in controlling the declining condition of the rangelands.

There were significant (P<0.05) treatment and time interactions on all measured colour parameters, TBARS and myoglobin forms. Fresh mince was lighter and had higher redness (a*) and yellowness (b*) values than mince from two months frozen stored meat. Hue angle for fresh mince remained stable throughout display whereas it increased for frozen/thawed mince. Fresh mince had lower TBARS values than frozen/thawed mince. Minced meat produced from frozen/thawed deer meat had higher surface met-myoglobin and total met-myoglobin percentages. Surface and total oxy-myoglobin percentage was higher in fresh mince. The first trial clearly showed colour and lipid stability differences between fresh mince and mince from frozen/thawed meat. It also showed that fresh mince has a longer retail display life than mince produced from frozen/thawed meat (six days and four days, respectively). In the second trial, the effects of frozen storage duration on colour and lipid stability were investigated. Twenty-four fallow deer were used. Twelve were harvested in June (6male 6female) and the other twelve in August (6 male 6female) of the same year.Twenty four hours after harvesting, the fore and hindquarter muscles of the carcasses were deboned, vacuum packed and kept at -20°C until October (i.e. 2months and 4months frozen storage period). Upon thawing, the meat was processed into mince following the same procedure used for the first trialand displayed for a fiveday period under retail display conditions. Frozen duration and gender had no effect (P>0.05) on the proximate composition of fallow deer meat. The total amount of saturated fatty acids (SFA) increased and total amount of poly unsaturated fatty acids (PUFA) decreased as frozen duration and display day increased (P<0.05). Frozen duration affected (P<0.01) lipid oxidation and percentage oxy-myoglobin. Mince pH and all colour parameters (L*, a*, b*,hue and chroma) differed (P<0.05) between treatments on day zero and three. Display day was a significant factor (P<0.05) on all measured parameters. By day three all parameters except pH showed signs of extended oxidation and discolouration as evidenced by reduced redness, decreased colour intensity and high TBARS values. This study showed that prolonged frozen storage negatively affects the colour and lipid stability of meat and increases oxidation of PUFAs during frozen storage. However, the study also suggests that although frozen/thawed meat has a shorter retail display shelf life; the proximate composition of the meat remains unchanged.]]> Wed 12 May 2021 16:01:16 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:29739 Wed 12 May 2021 15:59:46 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:27573 Wed 12 May 2021 15:59:38 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:29602 Wed 12 May 2021 15:49:40 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40582 Wed 12 May 2021 15:08:37 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:42735 Wed 12 May 2021 15:01:30 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40476 Wed 12 May 2021 14:52:22 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40401 0.05) between the APC of raw beef (4.8 Log CFU/g), mutton (3.7 Log CFU/g) and pork (2.8 Log CFU/g) and also the cooked beef (1.5 Log CFU/g), mutton (1.3 Log CFU/g) and pork (1.9 Log CFU/g) samples.
