Abstract
Background: Livestock rearing is one of the oldest and most important types of smallholder farming worldwide.The sustainability of livestock production depends on the efficient utilization of locally available resources. Sometraditional methods of raising livestock may offer valuable lessons in this regard. This study documented andevaluated local knowledge of wild forage plants in the Dulongjiang area in Southwest China in the context ofrearing mithun (Bos frontalis) in order to provide a sound evidence base for tree fodder selection and theestablishment of integrated tree-crop-livestock systems.
Methods: The snowball technique was used to identify key informants with specific knowledge about the topic.Free listing and semi-structured interviews were conducted with 58 households. Participatory investigation andtransit walks were used to investigate potential fodder species. Ethnobotanical information was collected,documented and organized.
Results: Overall, 142 wild forage plants from 58 families and 117 genera were identified. Species of the Poaceae,Rosaceae and Urticaceae families were most abundant, with 16, 14 and 11 species respectively identified as fodderplants. Our results indicated that tree/shrub forage plays a major role in the diet of mithun, unlike that of otherruminants. Mithun prefers to browse and move around the forest in search of food, particularly rough and evenbarbed leaves. Tree species like Debregeasia orientalis, Saurauia polyneura and Rubus species were identified asbeing important fodder sources. Farmers in this area have traditionally relied on common property resources suchas community-managed forests and grasslands to feed their livestock. Farmers have strong incentive to raisemithuns rather than other livestock species due to Dulong people’s cultural preferences.
Conclusions: The wide variety of plants cited by the informants demonstrate the importance of traditionalknowledge in gathering information about forage resources. This diversity also offers the prospect of identifyingpromising species which could be used as fodder plants. Identifying such species and tree fodder species inparticular could help smallholder farmers to integrate trees, livestock and crops as part of a sustainable farmingsystem.

BackgroundMany smallholder farming methods around the worldintegrate livestock and crop production. Such integrationprovides draught power for land management andmanure for maintaining cropland fertility. In addition,livestock are a critical source of nutrition. China’s con-sumption of meat, and particularly of pork, has in-creased tremendously as its economy has grown. 50 to80% of all pigs produced in China originate from small-holder farms [1, 2]. China’s rapid economic developmentand lifestyle transformation have resulted in a growingdemand for livestock, and as a result massive restructur-ing of the livestock sector is underway. New policies andtrade agreements have liberalized and industrializedChinese agriculture, which has enabled enormous in-creases in production. However, many smallholder farms,which remain a vital part of Chinese rural and indigenouscommunities, are struggling to survive in the new market-oriented agro-economy [3, 4].Although economically vulnerable, smallholder systems
which integrate crops and livestock continue to be a vitalpart of agricultural production in China [1, 5]. Smallholderfarmers rely on their observations and experience in feed-ing and managing their livestock. The sustainable produc-tion of livestock usually involves efficient utilisation oflocally available resources, particularly feed resources.Understanding the importance of wild forage plants isessential for the efficient utilisation of available forestresources [6, 7]. Exploring the potential for growing suchresources in intercropping systems with crops and live-stock could help smallholder farmers effectively use theirlimited land resources. Such integration could mitigatethe increasing pressure on land and forest resources gen-erated by growing demand for expansion of agriculturaland grazing land [8, 9].Compared to forage grass, tree fodder is particularly
important in providing livestock with nutritious foodduring the dry season when other feed sources are inlimited supply [10]. Documenting fodder plants andpromoting suitable types of tree fodder for use in homegardens or croplands could be an efficient way to im-prove sustainable livestock rearing and to change thefree grazing style to stall feeding in the mountain with-out damaging the environment. A combination of trad-itional and scientific knowledge has been shown tooptimize the selection of useful fodder plants [11].Indigenous people with long histories of livestock rear-
ing may have acquired valuable stores of knowledge aboutpotential fodder/forage resources. Traditional knowledgeof fodder plants has been documented in studies of differ-ent indigenous groups in several countries, such asEthiopia, Uganda, Nigeria, India, and Mexico [11–13]. InChina, there is an urgent need to document farmers’knowledge of fodder plants and apply it to the design of
tree-crop-livestock systems which could improve small-holder farming [14, 15]. Therefore, this study aims todocument local knowledge regarding utilisation and selec-tion of wild forage plants based on indigenous knowledge.The results of this study could be used to provide a short-list of fodder/forage resources for further nutritionalinvestigation and possible promotion.
MethodsStudy areaThe Dulong ethnic group, also known as Drung, is oneof the smallest ethnic groups in China and number only7000 people. Four thousand of them live in DulongjiangTownship, Gongshan County, Yunnan Province, China(Fig. 1). This township (27°44'9"N, 98°20'59"E) was thelast town in China to be linked by road (Fig. 2). Before1956, the Dulong people led a relatively isolated life.Slash-and-burn cultivation was practiced on the localmountains until the 1990s, when it was banned by thegovernment. The Dulong language has no script, andthe Dulong traditionally made records and transmittedmessage by means of engraving notches in wood andtying knots [16]. This lack of written records means thatlocal traditional knowledge is particularly vulnerable tobeing lost and forgotten. There is therefore an urgentneed to document the indigenous knowledge associatedwith this community.The study area is a typical alpine-gorge area, ranging
from an altitude of 3000 to 4000 meters with almost85% of the area on steep slopes of more than 25 degrees.The average rainfall is 3672.8 mm per annum [17]. Thearea contains 4000 species of higher plants belonging to280 families and 1068 genera. The Dulong people havean expansive knowledge of the diversity and nutritionalpotential of the local plants which they use for variouspurposes. According to elder informants, they have beenraising mithun (Bos frontalis) for more than a hundredyears. Mithun is a rare semi-domesticated bovine specieswhich is raised mountain areas, mainly for meat, and isdistributed only in India, China, Myanmar, Bhutan,Malaysia and Bangladesh [18]. Mithun plays an import-ant role in the economic, social and cultural life ofDulong people. The meat of mithun raised in the trad-itional way is high in protein (19.56%) and low in fat(0.36%) [19]. However, this species is vulnerable to ex-tinction according to the International Union for Con-servation of Nature and Natural Resources (IUCN) [20].China’s Tui Geng Huan Lin or “Returning Farmland to
Forest” (RFFP) program is the world’s largest and mostsuccessful payment for ecosystem services program. Thisprogram is a major contributor to China’s dramatic in-creases in forest cover from perhaps as low as 8% in1960 to about 21% in 2013 [21]. In Dulongjiang area,RFFP compensated rural households for the conversion

of upland farmland to forestland and financed the affor-estation of barren mountainsides. Traditionally, localfarmers would employ slash-and-burn cultivation toclear land for grass which would provide the mithunwith a fast-growing food source. However, after thegovernment banned slash-and-burn methods in 1990s,the expansion of forests has resulted in a lack of avail-able grassland, which poses a threat to the continuedraising of mithun. The use of fodder trees could providea solution to this problem, but currently inadequateinformation is available on the forage plants consumedby mithun.
In the present study, we 1) accessed farmers’ knowledgeof potential forage plants for mithun; 2) documentedsome potentially useful fodder trees/shrubs; and 3) priori-tized important species based on indigenous knowledge.Within this context, the objective of this study is theidentification, selection and evaluation of herbaceous andtree species in Dulongjiang area as sources of fodder formithun.
Data collectionOur field work revealed that mithun is commonly raisedonly in Maku(马库), Bapo(巴坡) and Kongdang(孔当)

villages, and that there are also a few mithuns in threeother villages in the Dulongjiang area. The first twovillages are near to Myanmar, which according to ourinformants is the origin of the local mithun. Our field-work was conducted accordingly in Bapo(巴坡) andMaku(马库) villages (Fig. 1) in 2015 and 2016. Fieldstudies included free lists, semi-structured interviewsand participatory investigation. A total of 58 key infor-mants were selected using snowball sampling. The agesof informants ranged from 23 to 71, and the mean agewas 45 years old. Because activities related to mithun aregenerally performed by men, we interviewed only twofemale informants.In the first stage of the field research, participants were
invited to free list all wild fodder plants favored bymithun. The interviews included the following questions:(1) What plants do mithun eat? (2) What are themithun’s favourite grass and tree fodder sources? (3)What makes mithun grow fast? (4) During the mithun’scalving and nursing periods, what plants do they prefer?(5) What habitats do mithun prefer? (6) What are thefeeding habits of mithun? (7) What are the main threatsto the mithun population? (8) How can we conserve thepresent population?In the second stage of the field research, researchers
made a transit walk accompanied by local villagers tocollect fodder plants and observe mithun browsing intheir natural habitat. Nomenclature of all vascular plantsfollows Flora of China, and the voucher specimens weredeposited at the herbarium of the Kunming Institute ofBotany, CAS (KUN).
Data analysisEthnobotanical information collected from 58 key infor-mants was documented and organized. Potential fodderspecies were prioritized according to the consensusreached by informants. Citation frequency (how many
times each plant was mentioned by the informants) wasused as a measure of consensus. The frequency ofcitation was the key factor in prioritizing the fodderspecies, while other ethnobotanical information such asmedicinal function, palatability and availability were alsoconsidered. Relevant graphical presentations of the doc-umented plants were prepared. Furthermore, the resultsof our field investigation of fodder plants for mithunwere compared with plant lists in the relevant publishedliterature to understand the diet of mithun fully.
Results and discussionTraditional knowledge of wild fodder plants amongDulong peopleOur study revealed that Dulongjiang mithun fed on ahighly diverse range of plants. The 58 informants told theinterviewers about 142 wild forage plants (Table 1) whichbelong to 58 families and 117 genera, including 61 speciesof tree/shrub fodder plants and 81 species of herb forageplants. The arrangement of Angiosperm families is in linewith the Angiosperm Phylogeny Website, version 13(http://www.mobot.org/MOBOT/Research/APweb/welco-me.html), and that of ferns follows Christenhusz et al.[22]. Species of the Poaceae, Rosaceae and Urticaceaefamily were cited most often, with 16, 14 and 11 speciesrespectively (Fig. 3). The wild fodder plants of the Poaceaefamily included not only various herbs but also tree fodderplants. These were mostly bamboos, and the genus Gaoli-gongshania, a bamboo, is endemic to this mountain area[23]. Forage plants of the Rosaceae and Urticaceae familieswere often shrubs and herbs respectively. Shrub forageplants of the Rosaceae family were mostly from the genusRubus. Forage plants from the Urticaceae family weremostly herbs. In addition to these three families, respon-dents also mentioned many wild forage plants from theAsteraceae, Lamiaceae, Polygonaceae and Rubiaceae fam-ilies, indicating a high local diversity of fodder plants.

Informants demonstrated a sophisticated knowledge ofnutritional characteristics such as nutritional value(fodder plants which enable mithun to grow rapidly),palatability and availability. About 32% of reported fod-ders were multifunctional, some of which were said tocause a bodyweight gain and shiny fur. Our informantslisted Arundo donax, Paris sp. and Erianthus longiseto-sus as being very important fodder plants. A. donax is aperennial herbaceous plant and promising energy plant,which could serve as an alternative to wood from short-rotation forestry [24–26]. 50% of informants claimedthat E. longisetosus made mithun fur very black andshiny. E. longisetosus is very popular among cattlefarmers and was most commonly used in dairy cowfeeding [27, 28]. Paris sp. is a perennial medicinal plantand is a promising candidate for the development ofanti-cancer drugs [29–31], and is important forageplant as identified by the informants. Overall, wildforage plants consumed by mithuns were diverse andabundant in the study site. Some studies point outthat herbivores have various mechanisms to preventabsorption or reduce the effect of ingested toxins inthe wild grazing [32, 33].The informants reported that mithun preferentially
consumed tender leaves (53.52%). The other parts mostfrequently consumed were whole plants, tender branches,fruits and bamboo shoots (Fig. 4). Of the plant speciescited, 33.8% had only one part of the plant often eaten bymithun, while the remaining species had more than two

parts mentioned as animal feed. Due to the climate of theDulongjiang area, most wild fodder plants documented inthe study can also be accessed in the winter, and there wasno significant seasonal difference in the plant species con-sumed by mithun.For mithun, less consumed fodder species usually were
the less distributed species in Dulongjiang area (Table 1),such as Cymbidium faberi, Pholidota articulate andUrtica ardens. But some common fodder species wereless consumed by mithuns in Dulongjiang area probablydue to their unpleasant taste, such as Blumea densifloraand Alnus nepalensis.
Feeding habits, prioritizing fodder trees/shrubs andpromotion possibilitiesMithun thrives on jungle forage, tree fodder, shrubs,herbs and other natural vegetation. They stay on themountain year-round, and farmers do not provide anyadditional feeding; they merely provide salt three to fivetimes monthly, especially if for some reason it is neces-sary to restrain the animals from freely ranging around(Fig. 5). Too much salt makes mithun more vulnerableto hypertension, so an adult mithun must be given lessthan three kilograms of salt per month.Mithun prefers to move around the forest and browse
selectively, particularly on rough or even spiny leaveslike those of Debregeasia orientalis, Saurauia polyneuraand forage plants in the genus Rubus, such as Rubuslineatus (Fig. 6). Preferred species are often leafy andwithout lots of stem, with a high leaf table and leaves oflow tensile strength [34]. The species found in the dietof the mithun match with the percentage of speciesfound in the botanical composition of the local forest[35]. According to a European study, the ungulates canplay a major role as seed dispersers for plant dispersalin forest habitats [36]. However, comparison of thisstudy’s results with those of Indian mithun reveals no
overlap between species consumed by mithun inDulongjiang and in India. This indicates that mithuncan adapt well to local environments in which theavailability of different foods is limited during someparts of the year [16, 37].Tree/shrub fodder plays a major role in the diet of
mithun, unlike that of other ruminants. In the Dulong-jiang area, tree and herb forage plants mostly belong tothe Poaceae family, and shrub fodder plants mostlybelong to the Rosaceae family. More than half of the 20most frequently cited fodder species in our survey(frequency ≥15) were trees or shrubs, and half ofthem belonged to the Poaceae family (Table 2). E.longisetosus and A. donax were abundant in the area,growing on riversides and hillsides at lower elevations.At the onset of winter, the mithun moves to lowerelevation regions with higher temperatures and moreavailable food, and these two perennial grasses becometheir important food source. Bamboo is also preferred bymithun but Dulongjiang has relatively low amounts ofbamboo. In interviews, Phyllostachys mannii was men-tioned more frequently than the other two (Chimono-bambusa armata and Fargesia praecipua) (Table 2).

This is probably because most of the interviewees sel-dom go high up into the mountains where the latter twospecies occur. Imperata cylindrica usually occurs indisturbed place, and it became very common inDulongjiang when both sides of the valley were con-verted to farmland. However, the recent reforestationprogram made it less common. In addition to Poa-ceae, two species of Urticaceae were also mentionedfrequently. D. orientalis is often found growing next tostreams, while Elatostema hookerianum grows in limitedamounts in the forest. S. polyneura and R. lineatus arewidely distributed throughout the Dulongjiang area, andwere used by a smallholder in Gongshan County to feedmithuns in captivity. Local residents also identified speciesmentioned above as being able to provide high qualitywoody fodder. Tree fodder plants often have multi-purpose uses. For example, P. mannii, C. armata and F.praecipua yield edible shoots; R. lineatus produces ediblefruits and planted as a courtyard ornament [38, 39]; fruitsof Saurauia have been important edible fruits sincehunger time [40, 41].The use of fodder trees may also bring other benefits
to farmers in Dulongjiang. The sale of tree fodder by-products by smallholder farmers provides an opportun-ity to boost household incomes in the study area.Integrating trees into farming practices often has directeffects on crop production such as weed suppressionand pest and disease reduction. Livestock such asmithun may also produce higher returns than single
crop production as much of the local area is steeplysloped. The use of fodder trees on cropland could becombined with raising mithun and growing crops in in-tegrated tree-crop-livestock systems which would makeefficient use of the available land resources withoutharming natural forests through agricultural extension.In many countries, fragmentation of land holdings
coupled with the declining productivity of public for-ests motivates farmers to cultivate more trees on theirprivate farmland in order to develop on-farm treefodder resources [42–44]. However, one of the disad-vantages of growing trees on crop land is a negativeimpact on crop yield. Some species may be suitablefor feeding livestock, but agronomically unsuccessful[45, 46]. Future introductions of fodder plants to newareas and systems may be more successful if basedon species and cultivars with long research pedigreesin the same agro-ecologies rather than on unknownspecies [47], and for which tree-crop interactions havebeen thoroughly investigated [48].For many local farming communities, agroforestry is
not a new land use practice but a proven productionstrategy [49]. Our results indicate that this wealth ofknowledge can be used to inform the selection of eco-logically suitable and economically beneficial foddertrees. These trees could form part of small-scale, mixedtree-crop-livestock systems which could play a majorrole in improving livelihoods and protecting natural eco-systems in mountain landscapes.

Mithun farming and livelihoods developmentCrop farming, raising livestock and running small busi-nesses were regarded as the most important economicactivities in Dulongjiang area. Livestock, especiallymithun and pigs, were in the past raised partly for cere-monial purpose but have now become an importantsource of income. Farmers in this area and the easternHimalayas have traditionally relied on common propertyresources such as forest and grasslands to feed their live-stock [27, 50]. Currently, Dulongjiang farmers use a jointmanagement system whereby a few families take turnsto check the numbers and condition of the mithun, andfeed them salt.When asked about the main threats to the mithun
population and means of protecting it, almost all localvillagers agreed that feeding mithun in stalls would be abetter way to avoid accidental death on the steep hill-sides as well as from predators such as bears. However,some worried that feeding mithun in this way couldmake them weak and thin. Mithun still contribute sig-nificantly to the livelihoods of traditional smallholders inDulongjiang area, and both the introduction of new hus-bandry practices and the planting of specialized forageplants, even in a limited way, present serious challenges.The sale of mithun could boost income, though theability to do this is often limited by a lack of capital withwhich to buy calves . According to some studies,mithuns are not usually raised for their milk, but theybecome accustomed to milking. Mithun produce around1–1.5 kg milk/day/animal, and the fat content of theirmilk varies from 11 to 13% [18, 28]. If mithun could bemore readily sold, farmers would have a stronger incen-tive to keep mithun, in addition to their cultural valueand provision of meat [51]. Farmers also prefer to planteconomically and commercially valuable trees overfodder trees [52].The time invested in raising mithun varied widely
among individual households. Members of a house-hold spent about five hours per week feeding theirmithuns salt and checking on them. Smallholder live-stock production also has the advantage of havinglower labor costs than either using hired labor onlarge-scale farms or the cut-and-carry feeding methodemployed in other regions [53].Efforts to improve livestock production in smallholder
farming systems face various challenges. First, the selec-tion of different species as candidates for planting foddertrees must take account both their ecological suitabilityand their potential for supporting local livelihoods [54].Second, farming systems in this area are usually lowinput, and under high-risk conditions, farmers arereluctant to invest in improved production technologies[55, 56]. However, in the Dulongjiang area, the local gov-ernment has strongly supported under-forest resource
development, and has offered each household Amomumtsaoko and Paris sp. seedlings for free. Therefore, thelocal government could play a vital role in establishingan efficient integrated tree-livestock-crop program andconvincing farmers that investing in such systems isworthwhile.The present study on the forage plants known by
Dulong people built upon their locally-developed experi-ence during the process of domestication of the mithun.Attention for the conservation of this rare animal is ne-cessary and proper management of forage source is oneof the important aspects in the step of conservation.Ethnobotanical experience from one community can beuseful for other community. Similarly, practices and pol-icy in one village could be useful for another village. Theconcept of integrated tree-livestock-crop can be accept-able and applicable in the regions like northeast Indiaand Myanmar where mithun are naturally distributed[16]. Therefore, the knowledge from Dulongjiang areacould be beneficial in the effective management offodder resources and mithun, and hence it could alsocontribute to the livelihoods development in the region.
ConclusionThe results of our research demonstrate the importanceof traditional knowledge in identifying suitable tree fodderspecies. In addition, the diversity of species mentioned byrespondents indicates that the study area is rich in forageplants which could be further investigated.According to the information provided by our infor-
mants, fodder species such as Erianthus longisetosus,Arundo donax and Paris sp. may have interesting nutri-tional properties. However, at present scientific knowledgeof these wild fodder species is too sparse to support thepromotion of fodder trees at the farm level. Padmakumaret al. had listed nutritional value of some species closelyrelated to our findings. This lead to the Ffurther researchinto these and other frequently-cited species which couldhelp farmers select fodder trees which are ecologicallysuitable and economically beneficial [57]. Tree fodderspecies such as Debregeasia orientalis and Saurauia poly-neura were highlighted by local farmers, as well as forageplants in the genus Rubus. Further studies are needed in-cluding a nutritional evaluation of various fodder speciesconsumed by mithun and researches into the effects ofdifferent fodder species on rumen microbial flora andenvironment of mithun.
