The hatching of nauplii was in a concentration dependent fashion, with hatching success decreasing with increase in concentration of extracts. Lethality of extracts determined based on Meyerʼs index of toxicity, showed that the acetone and hexane extracts of V. karroo were moderately toxic. The results of this study indicated that aqueous and methanolic extracts of Vachellia karroo pods were not toxic, therefore supporting its traditional therapeutic usage. This implies that rather than discard x the pods as is waste as it being currently done, Vachellia karroo pods could be salvaged and processed along with the leaves, thus reducing environmental pollution. Proximate parameters (moisture, ash, crude fibre, crude fat, proteins, and carbohydrate) were evaluated using ALASA methods, and elemental analysis by ICP-OES technique. Nutritional analysis showed that V. karroo pods had low content of crude fat and high content of crude fibre, ash, crude protein, and carbohydrate sufficient to meet the recommended dietary allowances. The pods were rich in major minerals Ca, K, P and Mg, with sufficient amount of trace elements Na, Fe, Zn, and Cu. The outcome of this study suggests that Vachellia karroo pods have good nutritional potentials to support or complement the recommended dietary allowance and could be a cheap source of essential nutrients that could help in ameliorating most nutritional challenges as well as contribute remarkably to the amount of nutrient intake in human and animal diets.]]> Wed 12 May 2021 15:01:01 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40846 Wed 12 May 2021 14:58:50 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40867 Wed 12 May 2021 14:51:07 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40864 Wed 12 May 2021 14:32:29 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40868 Wed 12 May 2021 14:32:27 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40850 Wed 12 May 2021 14:28:14 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:39998 Wed 12 May 2021 14:25:57 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40025 Wed 12 May 2021 14:25:16 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40023 Wed 12 May 2021 14:25:04 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40057 Wed 12 May 2021 14:14:08 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40872 Wed 12 May 2021 14:12:58 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40848 Wed 12 May 2021 14:08:59 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40064 Wed 12 May 2021 14:07:48 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40042 Wed 12 May 2021 14:06:35 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40018 0.05). Furthermore, histopathological evaluation of organs revealed that no abnormalities were in heart and liver and kidney of rats fed on the control diet, while mild congestion in the liver and myocardium (heart) were observed in rats fed with protein deficient diet. No visible abnormalities were observed in the heart, kidney and liver of animals on the PD 10 diet, but myocardial fibres showing intense eosinophilia was detected in heart muscles of rats fed PD and PD3 diets. In this study, MOLM had a negative impact on feed intake and growth performance of animals and haematology. Blood biochemistry and histology suggest that MOLM has the potential of defending the body against infection with hematinic and blood enhancing qualities. Protein deficiency led to a significant elevation in the serum lipid profile of rats especially cholesterol even with increase in MOLM. PD10 had the highest triglycerides content when compared to the control but was lower (p>0.05) to that of PD. There was an increase in crude fat, ADF, NDF and protein in faecal samples of rats supplemented with MOLM diets while a decrease in moisture and ash was observed compared to the control.Vitamin and mineral deficiency resulted in significant decrease in serum cholesterol, triglycerides and HDL-C when compared to the control. There was a slight increase in excretion for all elements with increasing MOLM. Total removal of minerals and vitamins from the VMD experimental diets seemed not to have any visible negative impact on performance of the rats probably because of residual micronutrients present in other ingredients used in the feed formulation. MOLM could not replace protein in protein deficient diets.]]> Wed 12 May 2021 14:01:43 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40870 Wed 12 May 2021 13:55:48 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40869 Wed 12 May 2021 13:55:38 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40871 Wed 12 May 2021 13:55:19 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40021 Wed 12 May 2021 13:51:48 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40873 0.05). Meat from steers on the SLG system had higher (P<0.05) drip loss, protein and fat contents and lower (P <0.05) shear force, moisture and ash contents than the two rotational grazing approaches (HPG and FCG). The HPG had higher (P < 0.05) total running and capital costs compared to SLG and FCG grazing systems. The SLG system had greater (P ≤ 0.05) gross and net income compared to FCG and HPG systems, respectively. Overall, all the grazing systems had comparable growth performance, carcass characteristics and meat quality but rotational grazing systems had lower gross income relative to the SLG grazing system.]]> Wed 12 May 2021 13:51:21 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40077 Wed 12 May 2021 13:45:48 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40044 Wed 12 May 2021 13:45:04 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:39995 Tue 07 May 2024 10:40:21 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:39878 Thu 13 May 2021 14:09:48 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:39875 Thu 13 May 2021 06:04:53 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:39880 Thu 13 May 2021 05:48:29 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:39883 Thu 13 May 2021 00:55:23 SAST ]]>
