Treatment 1 had a highest amount of malondialdehyde (MDA), treatment 4 had no effect (P>0.05) on MDA . Storage time had an effect (P<0.05) on MDA levels, except for on Day1 and Day7. Day2 had the highest amount of MDA (0.7±0.08). The use of MOLM as an additive in broiler diets reduced lipid oxidation in meat, and maintained the quality of the broiler meat during storage. It also did not have any adverse effects on the growth performance of broilers. Therefore, it has the potential to be used as an additive in broiler diets.]]> Wed 12 May 2021 20:59:33 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:2621 Wed 12 May 2021 19:37:43 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:1825 Wed 12 May 2021 19:18:30 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:5058 Wed 12 May 2021 19:09:50 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:20589 Wed 12 May 2021 18:34:01 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:1872 Wed 12 May 2021 18:29:24 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:5764 Wed 12 May 2021 18:19:30 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:2051 Wed 12 May 2021 17:12:54 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:2757 Wed 12 May 2021 16:47:09 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:20791 Wed 12 May 2021 16:40:44 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:27564 Wed 12 May 2021 16:38:19 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:11540 Wed 12 May 2021 16:36:11 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:1048 Wed 12 May 2021 16:28:27 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:38188 Wed 12 May 2021 16:18:27 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:40726 Wed 12 May 2021 14:49:05 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:40709 Wed 12 May 2021 14:39:47 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:40806 Wed 12 May 2021 13:58:16 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:906 Thu 13 May 2021 08:49:38 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:917 Thu 13 May 2021 06:30:38 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:30761 Thu 13 May 2021 06:08:25 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:1332 Thu 13 May 2021 05:57:48 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:3882 Thu 13 May 2021 05:55:26 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:11879 Thu 13 May 2021 05:25:43 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:28510 Thu 13 May 2021 04:21:14 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:1833 Thu 13 May 2021 04:01:00 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:21084 Thu 13 May 2021 03:26:04 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:8398 Thu 13 May 2021 03:25:37 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:5981 Thu 13 May 2021 03:20:07 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:39253 0.05) difference among all the treatments ranging from 1.44 to 1.62 in fresh forage and ranging from 1.31 to 1.50 in the dry forage. In terms of dry matter content, the control treatment had the highest dry matter content of 37.78percent, however, all the other treatments did not differ significantly (P < 0.05) from each other. There was no significant effect of P application (P > 0.05) in terms of ash, EE, ADF, CP, Ca, Mg, K, Na, P, Zn, Cu, Mn and Fe of the whole plant forage among the treatments. The application of 40 kg P/ha fertilizer significantly (P < 0.05) increased the NDF (51.16percent) of the whole plant of Mucuna compared to the other treatments which did not differ (p>0.05) among themselves. Within the stem fraction there were no significant (P > 0.05) differences among the treatments for the ash, EE, ADF, NDF, and CP, hemicellulose, Ca, Mg, K, P, Zn, Cu, Mn and Fe contents. However, the application of 40 kg P/ha fertilizer significantly (P < 0.05) increased the Na (0.05percent) content of the Mucuna stem fraction. In the leaf fraction of Mucuna there was no significant (P > 0.05) differences in terms of ash, EE, ADF, NDF, CP, hemicellulose, Ca, K, P, Zn, Cu, Mn and Fe among the treatments. However, the application of 20 kg P/ha fertilizer significantly (P < 0.05) increased the Mg (0.52percent) of the Mucuna leaves compared to the other treatments. Therefore the study has shown that increase in P application (60 kg P/ha) has no major effect in the nutrient content of Mucuna. Furthermore, it is recommended that Mucuna can be grown as a protein supplement, based on the CP content values that were recorded in this study and to provide maintenance requirements for ruminants. It was therefore concluded that phosphorus fertilization particularly 60 kg P/ha is necessary and required for optimum growth of Mucuna pruriens in order to increase forage yield. Based on the nutrient content result it was concluded that there was no effect of P fertilizer application levels on the nutrient content of Mucuna pruriens in Alice.]]> Thu 13 May 2021 02:28:50 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:4572 Thu 13 May 2021 02:07:21 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:39673 Thu 13 May 2021 01:35:09 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:4254 Thu 13 May 2021 01:19:44 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:39099 0.05) sperm concentration (1.20 ± 3.68x109 sperm/ml) than the EE samples (1.11 ± 3.51x109 sperm/ml). The percentage live sperm in the fresh semen samples did not differ among Namaqua Afrikaner (67.76 ± 1.94percent), Dohne Merino (68.59 ± 1.94percent) and Dorper (72.82 ± 1.98percent) rams. The percentage live sperm for all three breeds dropped considerably after freezing to 17.76 ± 2.03percent, 17.86 ± 2.03percent and 22.72 ± 2.07percent respectively. It remained constant for all the breeds from 7 until 90 days after freezing, indicating that length of storage should not have an effect on percentage live sperm for semen collected via AV or EE. Percentage live sperm of the frozen-thawed semen of the Namaqua rams was lower than that of the Dorper rams, indicating that the Namaqua semen collected via EE did not freeze as well as that of the Dorper semen. In conclusion, neither fresh nor frozen-thawed Dorper and Dohne Merino semen collected via EE did differ significantly. Furthermore, except for semen volume, Dorper and Dohne Merino semen collected via AV did not differ significantly whether evaluated as fresh or frozen-thawed semen. However, both Dorper and Dohne Merino rams produced semen with higher motility and a higher percentage live sperm post-thaw when the semen samples were collected via an AV than via EE. From these results it can therefore be postulated that if Namaqua semen were collected via AV it could have a higher post-thaw percentage live sperm than if semen was collected via EE. Advanced further studies are necessary to investigate the reason for the lower post-thaw survival rate of sperm of the Namaqua Afrikaner rams. This is necessary as semen stored in a cryobank for breeding and conservation purposes for this endangered breed has to be of high quality. Such resources as cryobanks are expensive and funds cannot be wasted on preserving inferior samples that could not fertilize an ovum when needed. The low percentage of live sperm obtained with the frozen-thawed samples in this, as well as other studies on indigenous breeds, is an indication that further research is needed into more suitable freezing protocols. It can be concluded that Namaqua Afrikaner semen cannot be frozen successfully for the purpose of storage in a cryobank, when using a freezing protocol based on Triladyl® as extender. Furthermore, any increase in post-thaw survival rate of sperm will be beneficial and it is therefore suggested that all efforts be made to solve the problem of the Namaqua Afrikaner rams that do not want to ejaculate into an artificial vagina.]]> Thu 13 May 2021 00:06:08 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:35443 Thu 13 May 2021 00:00:07 SAST ]]>
