Ethnoveterinary medicine practices among Tsonga speaking people of South Africa

Rapid Rural Appraisal methods were used to collate and code the indigenous knowledge on animal healthcare of Tsonga speaking people of South Africa. There was a rapport between local disease names as described by their clinical signs by the farmers and the local veterinary services important disease list. The perceived causes of diseases were physico-biological elements and no reference to ancestral guidance was recorded. Males and old people were more knowledgeable but females and young people did show a certain degree of confidence during general discussions. Plants were more frequently used than other non-conventional remedies with cattle being the most treated animals. Farmers reported using 19 plant species belonging to 12 families. Plants were collected from the wild when needed and no specific storage system was used. They were administered as decoctions or infusions of single plants. These remedies were used not only as alternatives to expensive pharmaceutical products but also because in certain diseases or chronic cases, they were thought to be more efficacious.     

Plants as de-worming agents of livestock in the Nordic countries: historical perspective, popular beliefs and prospects for the future.

Preparations derived from plants were the original therapeutic interventions used by man to control diseases (including parasites), both within humans and livestock. Development of herbal products depended upon local botanical flora with the result that different remedies tended to develop in different parts of the world. Nevertheless, in some instances, the same or related plants were used over wide geographic regions, which also was the result of communication and/or the importation of plant material of high repute. Thus, the Nordic countries have an ancient, rich and diverse history of plant derived anthelmintic medications for human and animal use. Although some of the more commonly used herbal de-wormers were derived from imported plants, or their products, many are from endemic plants or those that thrive in the Scandinavian environment. With the advent of the modern chemotherapeutic era, and the discovery, development and marketing of a seemingly unlimited variety of highly efficacious, safe synthetic chemicals with very wide spectra of activities, herbal remedies virtually disappeared from the consciousness--at least in the Western world. This attitude is now rapidly changing. There is a widespread resurgence in natural product medication, driven by major threats posed by multi-resistant pest, or disease, organisms and the diminishing public perceptions that synthetic chemicals are the panacea to health and disease control. This review attempts to provide a comprehensive account of the depth of historical Nordic information available on herbal de-wormers, with emphasis on livestock and to provide some insights on potentially rewarding areas of "re-discovery" and scientific evaluation in this field.     

Use of plants in novel approaches for control of gastrointestinal helminths in livestock with emphasis on small ruminants

Helminth infections are a major cause for reduced productivity in livestock, particularly those owned by the poor worldwide. Phytomedicine has been used for eons by farmers and traditional healers to treat parasitism and improve performance of livestock, and many modern commercial medicines are derived from plants. However, scientific evidence on the anti-parasitic efficacy of most plant products is limited, regardless of their wide ethnoveterinary usage. Scientific validation of the anti-parasitic effects and possible side-effects of plant products in ruminants is necessary prior to their adoption as a novel method for parasite control. A variety of methods has been explored to validate the anthelmintic properties of such plant remedies, both in vivo and in vitro. In vitro assays are useful as pre-screens of activity and are mainly performed with the free-living rather than parasitic stages of nematodes. Concentrations of potentially active substances used in vitro do not always correspond to in vivo bioavailability. Therefore, in vitro assays should always be accompanied by in vivo studies when used to validate the anthelmintic properties of plant remedies. In vivo controlled studies have shown that plant remedies have in most instances resulted in reductions in the level of parasitism much lower than those observed with anthelmintic drugs. Whether it is necessary or not to achieve very high efficacy in order for plant remedies to have a role in the control of parasitism depends on the determination of biologically important levels of reduction of parasitism and it will be required prior to the wide-scale use of plant products for parasite control. Similarly, standardisation of validation studies in reference to the numbers of animals required for in vivo studies to measure direct anthelmintic effects of a plant needs to be established. Although in many cases the active compounds in the herbal remedies have not been fully identified, plant enzymes, such as cysteine proteinases, or secondary metabolites, such as alkaloids, glycosides and tannins have shown dose-dependent anti-parasitic properties. However, as some of the active compounds may also have anti-nutritional effects, such as reduced food intake and performance, it is essential to validate the anti-parasitic effects of plant products in relation to their potential anti-nutritional and other side effects. A concerted effort on isolation, development, and validation of the effects of these herbal remedies will have to be undertaken before their wider acceptance.     

Ethnoveterinary medicine in the Arribes del Duero,western Spain

Currently, traditional ethnoveterinary practices are rare in Europe and the plants used previously have been replaced by the modern drugs used by national veterinary services. However, in some rural areas of the Mediterranean basin these traditional practices persist. Here we analyze the plant resources still used, or that have been used up until recently, for the treatment of the health and comfort of animals in a region in the central-western part of the Iberian Peninsula, the Arribes del Duero. We document the use of 84 species, belonging to 39 families (with a total of 2243 use-reports), and 62 herbal remedies based on the use of a single plant species (43) and cited by at least three independent informants. The veterinary use of the Ranunculaceae Clematis campaniflora is reported for the first time. We also identify several plants used as bedding or fodder for livestock and discuss the relevance of some toxic plants and some “magical-curative” aspects reported in the territory.     

Constraints and challenges of meeting the water requirements of livestock in Ethiopia: cases of Lume and Siraro districts

Compared to the total water use in livestock production systems, water for livestock drinking is small in amount but is an important requirement for health and productivity of animals. This study was carried out to assess constraints and challenges of meeting drinking water requirements of livestock in rural mixed smallholder crop–livestock farming districts in the Ethiopian Rift Valley area. Data was collected by individual interviews with randomly selected respondents and farmer group discussions. Farmers ranked feed and water scarcity as the two most important constraints for livestock husbandry, although the ranking order differed between districts and villages. Poor quality water was a concern for the communities in proximity to urban settlements or industrial establishments. Water provision for livestock was challenging during the dry season, since alternative water sources dried up or were polluted. Though rainwater harvesting by dugout constructions was practiced to cope with water scarcity, farmers indicated that mismanagement of the harvested water was posing health risks on both livestock and people. A sustainable water provision for livestock in the area, thus, depends on use of different water sources (intermittent or perennial) that should be properly managed. Industrial establishments should adopt an environment-friendly production to minimize pollution of water resources used for livestock consumption. Technical support to farmers is required in proper design and use of existing rainwater harvesting systems. Further investigations are recommended on effect of poor quality water (perceived by farmers) on performance of livestock.     

Use of ethnoveterinary medicinal plants in cattle by Setswana-speaking people in the Madikwe area of the North West Province of South Africa

Rapid Rural Appraisal (RRA) methods were employed to document the use of ethnoveterinary medicinal plants in cattle by Setswana-speaking people in the Madikwe area of the North West Province of South Africa. The study indicated that Setswana-speaking people in the North West Province have a rich heritage of ethnoveterinary knowledge, which includes all aspects of ethnoveterinary medicinal plant use. Information was gathered from informants through individual interviews, group interviews, guided field walks and observations. Ethnoveterinary uses in cattle of 45 plant species representing 24 families were recorded. Plants were used in 84% of the total number of recorded ethnoveterinary remedies. These plants were used alone (64%) or in mixtures (36%) for 29 indications. The most important indications were retained placenta, diarrhoea, gallsickness, fractures, eye inflammation, general ailments, fertility enhancement, general gastrointestinal problems, heartwater, internal parasites, coughing, redwater and reduction of tick burden. Plant materials were prepared in various ways including infusion, decoction, ground fresh material, sap expressed from fresh material, charred and dried. The most common dosage form was a liquid for oral dosing. Other dosage forms included drops, licks, ointments, lotions and powders. Liquid remedies for oral dosing were always administered using a bottle. Medicinal plant material was preferably stored in a dried form in a cool place out of direct sunlight and wind. Lack of transfer of ethnoveterinary knowledge to younger generations puts this knowledge at risk. RRA was found to be a successful method of investigation for the study of ethnoveterinary medicine.     

Ethnoindicators of Environmental Change: Local Knowledge used for Rangeland Management Among Smallholders of Patagonia

The current degradation crisis in arid and semiarid lands is creating severe economic and social difficulties, aggravating the food situation and greatly affecting the least developed countries and small farmers around the world. However, little attention has been given to the wealth of knowledge held by rural livestock farmers on this phenomenon, particularly those linked to environmental indicators. The objective of this work was to investigate plant attributes used by smallholders as ethnoindicators of short- and long-term environmental change. Using an ethnoecological approach, the study was carried out along with rural livestock smallholders who inhabit the central-northern Patagonian plateau. Open and semistructured interviews were carried out with 35 informants who were strongly associated with subsistence livestock farming. A total of 23 plant species were registered as being involved in detection of environmental change. The types of environmental change recorded were short term (such as droughts) and long term (such as desertification). These plants presented 14 different indicators, involving various life forms: gramineous or graminoid plants (65%), woody species (30%), and plants that are not gramineous or graminoid (5%). The plant community attributes that functioned as indicators were presence/absence of species, species abundance, and visible plant characteristics such as exposed roots, changes in plant architecture, and/or changes in phenology. The traits used as indicators provide complex information that is essential to the understanding of plant development and the structure and functioning of the managed ecosystem. Key lessons from this work include the following: The integration of plant ethnoindicators is important for the successful diagnosis and permanent monitoring of arid lands; and development plans incorporating indicators constructed with the involvement of the local people, as well as the rangeland professionals, must help to mobilize knowledge and practice on an equal basis.     

A Social Approach to the Validation of Traditional Veterinary Remedies – The Anthra Project

Anthra, an organization of women veterinary scientists working in the field of livestock production and development, has been involved since 1996 in a research project to document and validate local ethnoveterinary and animal management practices carried out by livestock-rearing communities in different parts of the states of Andhra Pradesh and Maharashtra in India. Communal knowledge and innovation are an integral part of the day-to-day healing and management practices of farmers in all areas and over 80% of farmers continue to use these because they are easily and quickly available, especially in remote villages. However, this knowledge is today rapidly being lost. Farmers, both men and women, have expressed a keen desire to increase their own knowledge of these systems. This paper outlines the validation framework evolved by Anthra, wherein farmers using these medicines are actively participating in an evaluation process. Major findings are that local practices are effective, participating farmers use them confidently and other farmers are keen to use and increase their knowledge of them.     

In vitro screening of two Nigerian medicinal plants (Vernonia amygdalina and Annona senegalensis) for anthelmintic activity

Vernonia amygdalina and Annona senegalensis, two plants used by local/smallholder livestock farmers in Nigeria as anthelmintic were screened for in vitro anthelmintic activity using Haemonchus contortus eggs. The extract of V. amygdalina did not show any significant activity at concentrations up to 11.2mg/ml. The extract of A. senegalensis showed significant (P<0.001) reduction in egg hatch at a concentration of 7.1mg/ml. The in vitro fecal culture of eggs with A. senegalensis showed significant (P<0.001) reductions in larval recovery with increasing concentrations from 1 to 10% ((w/w) in fecal culture) when whole ground plant material was used. Although traditional veterinary healers and local livestock farmers claim both plants are effective as anthelmintics, our result indicate that only A. senegalensis showed promising anthelmintic activity especially with use of ground whole plant materials as used by some farmers.     

Herbal medicine: potential for intoxication and interactions with conventional drugs

The use of herbal remedies for the prevention and treatment of a variety of illnesses in small animals has increased tremendously in recent years. Whereas most herbal remedies, when used as directed and under the supervision of knowledgeable individuals, are safe, the potential for adverse effects or intoxications certainly exists. Due to inherent toxicity, some herbal remedies should not be used under any circumstance. In addition, because nearly all herbal remedies contain multiple, biologically active constituents, interaction with conventional drugs is a concern. It is incumbent upon clinicians to be aware of those herbs that can cause intoxication, and to be cognizant of potential herb-drug interactions. There are a number of evidence-based resources available to assist clinicians in the safe use of herbal remedies.     

Traditional remedies used for the treatment of cattle wounds and myiasis in Amatola Basin, Eastern Cape Province, South Africa

A questionnaire survey was carried out to document traditional remedies used in the treatment of cattle wounds and myiasis in Amatola Basin. Eighty-three cattle farmers from nine villages were interviewed. The majority of respondents (67.9%) use traditional remedies for treatment of these conditions. However, 25.9% of them use a combination of traditional remedies with conventional medicines. The survey revealed that 13 medicinal plants belonging to 11 families were used. Aloe ferox, Prunus persica and Phytolacca heptandra were, however, the most commonly used. Leaves are the most frequently used plant part, often prepared as an infusion. Other non-plant remedies used include disinfectants, antiseptics as well as diesel and petrol. Manual removal of maggots from wounds was also practise and treatment is usually continued until the wound heals.     

Indigenous knowledge on the nutritional quality of urban and peri-urban livestock feed resources in Kampala, Uganda

This study identified the indigenous criteria used by livestock farmers in urban and peri-urban areas of Kampala to assess the nutritional quality of available feed resources. Focus group discussions and questionnaire interviews (with a total of 120 livestock farming households) were conducted. The findings showed that banana peels, leftover food and own-mixed feeds were the most commonly used feed resources for cattle, pigs and chickens, respectively. Farmers use several indigenous criteria to judge the nutritional quality of the available feed resources. These included perceived effects on disease resistance, feed intake, growth/body condition, hair coat appearance, faecal output, faecal texture and level of production, among others. According to farmers, animals offered with a feed resource of good nutritional quality are more resistant to diseases, ingest much of the feed, gain weight with well-filled bodies, have smooth hair coats, produce large quantities of faeces that are not too firm or watery and exhibit good performance (lactating cows produce more milk, sows produce piglets of good body size, hens lay more eggs of normal size, etc.). Although this indigenous knowledge exists, farmers put more importance on availability and cost as opposed to nutritional quality when choosing feed resources. This explains why banana peels were among the feed resources perceived to be of low nutritional quality but, at the same time, were found to be the most commonly used. Hence, there is a need to sensitise farmers on the importance of nutritional quality in ensuring better and efficient utilisation of the available feed resources.     

The use of trees,shrubs and herbs in livestock production by communal farmers in northern KwaZulu-Natal,South Africa

A survey of the use of trees, shrubs and herbs for livestock production was conducted through questionnaires among 90 farmers in the communal areas of northern KwaZulu-Natal in South Africa. The areas surveyed were located at Mtubatuba, Hluhluwe, Kwadlangezwa and Jozini. All the farmers questioned were found to own some form of livestock, mostly the Nguni breed. The commonly perceived sources of constraints on livestock production were external and internal parasites. The well known plants reported to be consumed by the animals were Vitellariopsis arginata and Rhus gueinzii. Most of the farmers (27.7%) used Cissus quadrangularis and Gnidia kraussiana for treating worm infestations and coughs in livestock. Plants used for increasing milk production were Crinum macowanii and Sarcostemma viminale. The well known plant species detrimental to livestock was Moraea spathulata, which causes diarrhoea and death.     

Land Manager Perceptions of Opportunities and Constraints of Using Livestock to Manage Invasive Plants

The ecological impacts of rangeland invasive plants have been widely documented, but the social aspects of how managers perceive their impacts and options for control have been relatively understudied, and successful, long-term invasive plant management programs are limited. In particular, though a growing body of research has identified livestock grazing as the most practical and economical tool for controlling invasive rangeland plants, to date there has not been a systematic assessment of the challenges and opportunities producers and other land managers see as most important when considering using livestock to manage invasive plants. In-depth, semistructured interviews with California annual grass and hardwood rangeland ranchers, public agency personnel, and nongovernmental organization land managers were used to address this need. Although interviewees broadly agreed that grazing could be an effective management tool, differences emerged among the three groups in how they prioritized invasive plant control, the amount of resources devoted to control, and the grazing strategies employed. Interviewees identified key challenges that hinder broad-scale adoption of control efforts, including the potential incompatibility of invasive plant management and livestock production; a lack of secure, long-term access to land for many ranchers; incomplete or insufficient information, such as the location or extent of infestations or the economic impacts to operations of invasive plants; and the temporal and spatial variability of the ecosystem. By identifying key socioecological drivers that influence the degree to which livestock are used to manage invasive plants, this study was able to identify potential pathways to move our growing understanding of the science of targeted grazing into practice. Research, extension, and grazing programs that address these barriers should help increase the extent to which we can effectively use livestock to slow and perhaps reverse the spread of some of our most serious rangeland weeds.     

Willingness to pay for cattle and buffalo insurance: an analysis of dairy farmers in central India

In India, insurance market especially in agricultural sector is usually underdeveloped. The idea of livestock insurance emerged in India before three decades, yet, it has not operated in a significant way till date. It is well noted that livestock insurance scheme is the relevant strategy in managing different risks related to livestock farming but very little attention has been paid to address the livestock insurance needs of the dairy farmers. This study, therefore, addresses the basic question that how many people and to what extent they are willing to pay for livestock insurance and determine the main factors which influence insurance participation of dairy farmers. The data was collected from Gorakhpur district of Uttar Pradesh in India with a sample survey of 120 cattle and buffalo farmers. For eliciting willingness to pay, a contingent valuation scenario was presented to dairy animal owners in the group of five to six. A logit discrete binary regression model was used to know the factors influencing adoption of livestock insurance. The results suggest that most of the farmers were willing to participate in cattle and buffalo insurance. The amount of premium varies across different breeds of dairy animals. The low level of education of many dairy farmers have negatively influenced the decision to purchase livestock insurance. Farmers having more experience in rearing dairy animals are more likely to be willing to pay for cattle and buffalo insurance.     

Ethnoveterinary plant preparations as livestock dewormers: practices, popular beliefs, pitfalls and prospects for the future

Ethnomedicine is an integral part of traditional medical practices in many countries of the developing world. A large proportion of the population uses this form of treatment for primary health care and for the treatment of ailments in their livestock. Livestock is a major asset for resource-poor smallholder farmers and pastoralists throughout the world and internal parasites are recognized by these communities as having an impact on livestock health. Parasitic infections are among those infections that traditional healers confidently treat and against which an enormous variety of remedies exist. Many of these are based on the use of plant preparations. Although various methods have been used for the validation of traditional phytomedical preparations, there is a lack of standardization of these procedures. The present study is aimed at providing an overview of ethnoveterinary deworming preparations, the various methods that have been used in their validation and the future prospects for their use against helminth parasites of ruminant livestock in developing countries, with an emphasis on nematode parasites. Recommendations are made on the procedures that should be followed to conduct in vivo and in vitro assays. Fostering better interaction between traditional healers and scientists is advocated to prevent harmful overexploitation, both of local knowledge and of plant species that may have effects against nematode parasites.

The Use of Trypanocides and Antibiotics by Maasai Pastoralists

Information was collected on the use of veterinary drugs by Maasai pastoralists in an area of Kenya where tsetse flies and trypanosomosis occur. Three herds of cattle were followed for between 4 and 5 years and records were kept of every veterinary drug treatment given by the livestock owners. Almost all treatments were either with the trypanocides homidium or diminazene, or with oxytetracycline by intramuscular injection. The rate of trypanocide use varied between 0.66 and 1.56 treatments per animal per year, while oxytetracycline use was between 0.20 and 1.00 treatments per animal per year. Farmers were injecting these drugs in the absence of veterinary supervision, obtaining their supplies mainly from local village shops or informal traders. Underdosing with trypanocides appeared to be uncommon and the indications were that farmers generally gave the drugs at dosage rates above the recommended standard dose. Accurate information on the dose rates of oxytetracycline could not be obtained, but it was noted that in most cases farmers gave a single injection rather than a course of treatment. In a proportion of cases, trypanocides and antibiotics were mixed together before injection. The farmers administered the drugs when disease was recognized and were rarely using trypanocides as prophylactics. Although necessity forces the livestock owners to obtain and use these drugs without veterinary supervision, there are concerns with regard to the possibility of drug misuse and the development of drug resistance.     

Livestock Farmers Engage in Ecotourism as a Result of Beliefs and Attitudes Toward Wildlife on Communal Lands in Namibia

An individual’s decision to support conservation efforts can be affected by personal attitudes. We interviewed 100 indigenous livestock farmers on Ehirovipuka and ≠Khoadi //Hôas communal conservancies in Namibia. As conservancy support groups work with farmers, there is a need to understand what influences farmer decisions to engage in ecotourism activities for livelihood. We evaluated cognitive characteristics of farmers and their attitudes toward 10 species of wildlife. Farmers had negative attitudes toward predators, more positive attitudes toward meat-producing species and a hornbill (Tockus sp.), and moderate attitudes toward African elephant (Loxodonta africana) and black rhino (Diceros bicornis), which can cause damage but also attract tourists. We show support for a partial mediation model in which cognitive characteristics of farmers predicted attitudes toward predators and damage animals. The attitudes toward these species, in turn, predicted participation in the ecotourism industry.     

Spatial,temporal and attitudinal dimensions of conflict between predators and small-livestock farmers in the Central Karoo§

Conflict between predators and small-livestock farmers is a global phenomenon adversely impacting the preservation of wildlife, the well-being of livestock and human livelihoods. Such conflict is pervasive in the Karoo region of South Africa but its contemporary history and various causes remain poorly understood. In this study, we interviewed 77 small-livestock farmers in the Central Karoo between July 2014 and March 2015 to (1) assess the spatio-temporal distribution and severity of the reported predation problems with the main regional predators of livestock (black-backed jackal, caracal and baboon) and (2) describe the perceived reasons for changes in predator numbers. Farmers reported that serious predation problems have increased since the 1990s for all three predators. Jackal predation appears to have re-emerged, particularly since the 2000s, while baboon predation seems to have escalated rapidly since 2014 for select farmers. Farms with more rugged terrain were more likely to experience serious problems with baboons and caracal but ruggedness did not predict the year of onset of problems. Farmers perceive predator numbers to be increasing and attribute this trend to declining government support for predator management, changes in farming practices and the associated increase in suitable predator habitat, from which they can recolonise commercial farms.
