“…[ 105 ] affirms the need to find substitutive treatments for the control of endo- and ectoparasites in Angolan livestock by using bioactive plants. Moreover, due to their easier and more rapid metabolization rate, phytochemicals reduce the risk of contaminants in meat and dairy products [ 106 ].…”

This study delves into the ethnoveterinary medicine (EVM) practiced by pastoralists along the transhumance routes in southwestern Angola. Within the framework of three cooperation projects, we conducted 434 interviews, collecting information on 89 taxa used for treating 16 livestock diseases. The most cited species was Ptaeroxylon obliquum (132 citations), followed by Salvadora persica (59) and Elaeodendron transvaalense (49). Contagious bovine pleuropneumonia (CBPP) was the disease most cited (223 citations; 44 species), followed by wounds (95; 20) and Newcastle (86; 14). We found that 30 species and 48 uses have not been previously reported in the ethnoveterinary literature. Jaccard index (mean value = 0.13) showed a greatly diversified knowledge among the ethnic groups: Kuvale and Nyaneka were the most knowledgeable and should be included in the various strategies for disseminating EVM in the area. Most informants recognized that abundance of some species decreased in the last years as a result of human activities and climatic changes. Finally, we discuss challenges in preserving the EVM in the area. Our findings suggest that preservation of the EVM in southwestern Angola is widely impacted by the access to biomedicine. Future studies should investigate the opportunity to integrate traditional medicine into mainstream development projects, which is crucial for decolonizing the veterinary sector in Angola.

“…The increasing incidence of drug resistance in most pathogenic bacteria and parasites that cause economic loss in animals/livestock production calls for the development of new sources for medication [60,61]. Among to the 104 woody plants with ethnoveterinary uses in South Africa (Table 2), approximately 20% were screened for their relevant biological activities (e.g., antibacterial, anthelmintic, and antioxidant) and safety (cytotoxicity) level.…”

Globally, the use of ethnoveterinary medicine as remedies for animal health among different ethnic groups justify the need for a systematic exploration to enhance their potential. In addition, the increasing popularity and utilisation of woody plants remain common in traditional medicine, which may be attributed to their inherent benefits. The current review was aimed at analysing ethnoveterinary surveys, biological activities, and secondary metabolites/phytochemical profiles of the woody plants of South Africa. Eligible literature (period: 2000 to 2020) were retrieved from different databases such as Google Scholar, PubMed, Sabinet, and Science Direct. Based on the inclusion and exclusion criteria, 20 ethnoveterinary surveys were eligible and were subjected to further analysis. We identified 104 woody plant species from 44 plant families that are used in the treatment of different diseases in animals, particularly cattle (70%) and goats (20%). The most mentioned (with six citations) woody plants were Terminalia sericea Burch. ex DC and Ziziphus mucronata Willd., which were followed by plants with five (Cussonia spicata Thunb., Pterocarpus angolensis DC and Vachellia karroo (Hayne) Banfi & Galasso) or four (Acokanthera oppositifolia (Lam.) Codd, Cassia abbreviata Oliv., and Strychnos henningsii Gilg) individual mentions. The most dominant families were Fabaceae (19%), Apocynaceae (5.8%), Rubiaceae (5.8%), Anacardiaceae (4.8%), Combretaceae (4.8%), Euphorbiaceae (4.8%), Malvaceae (4.8%), Rhamnaceae (4.8%), and Celastraceae (3.8%). Bark (33%), leaves (29%), and roots (19%) were the plant parts dominantly used to prepare remedies for ethnoveterinary medicine. An estimated 20% of woody plants have been screened for antimicrobial, anthelmintic, antioxidant, and cytotoxicity effects. Phytochemical profiles established a rich pool of valuable secondary metabolites (phenolic, flavonoids and condensed tannins) that may be responsible for the exerted biological activities. Overall, the significant portion of woody plants lacking empirical evidence on their biological effects indicates a major knowledge gap that requires more research efforts.

“…have been attributed to the polysaccharides contained in the gel of the leaf and many of its effects may derive from its activity on intestinal function, thus influencing absorption and availability of key substances (Sharma et al 2014). However, natural products, originating from plants, have an immensely diverse array of structures, which may serve as possible lead compounds for further development into therapeutic treatments and they may be considered as an alternative to the routine pharmaceutical approach (Yarnell 2007;Eloff & Mcgaw 2008).…”

The aim of the present study was to evaluate the effects of Aloe arborescens on organic matter digestibility (OMD), cumulative gas (OMCV) and short chain fatty acids (SCFA) production, using the in vitro gas production technique (IVGPT). Three adult cats were fed with a commercial diet (CP 31.21; EE 16.64% as fed) for 20 days before the collection of their faeces used as inoculum. The same diet, used as substrate, was incubated in vitro supplemented with different amounts (0, 0.7, 1.6 and 3.2%) of lyophilised Aloe arborescens. OMD, OMCV and SCFA significantly decreased with the increase of Aloe addition; an increase of L-lactic acid production was detected, even if pH was within physiological range. A potential prebiotic role of the Aloe arborescens carbohydrates was hypothesised in cats, but it needs further investigations. As a whole, our results show that IVGPT can represent a useful tool for nutritional evaluation of novel ingredient and/or additive also in cats.
