Many
reasons have been given why national governments in
Recognizing
the important roles of buffaloes on small farms in rural area of Asia, Ross Cockrill (1994), one of the world livestock authorities, strongly noted
that “Of all the domestic animals which serve mankind the Asian buffalo holds
the greatest promise and potential for production”.
It is well
recognized that most small farms (75 to 85%) depend on rain-fed agricultural
production. They have practiced farming
or integrated farming for many centuries.
Buffaloes have been incorporated as a vital component in these
sustainable agricultural production systems.
They continue to provide renewable resources in terms of draught power
and manure, while meat or milk are secondary products in these systems. It is very evident in
In most
developing countries, draught animal power remains an important source of farm
power in spite of the increasing use of petroleum-based power in certain areas
of some countries, such as
In the last
two decades, farm mechanization has increased at various rates in many Asian
countries. This raises questions
concerning the future of draught animal power.
But it is clear that the benefit of mechanization on crop yield will be
realized only when other production factors such as fertilizer, insecticide,
and irrigation become available and economical.
It is therefore evident that under the prevailing rain-fed conditions
and subsistence farming in developing countries mechanization has not played a
major role in sustainable crop production.
For
Another
important aspect of sustainable integrated farming systems practiced by rural
smallholders is the utilization of crop wastes and by-products, such as cereal
straws, maize and sorghum stovers, pineapple waste, sweet potato vines and
groundnut vines, by ruminant animals.
Buffaloes are known to digest such poor-quality roughages more
efficiently than cattle, and in developing countries small-farmers commonly use
crop wastes and by-products to feed animals, especially buffaloes. In some areas, where farmers do not raise
buffaloes or other ruminants, they burn straw and stubble in order to dispose
of them; this is wasteful, creates pollution, and sometimes causes serious
accidents.
It has been
shown that the yield of wheat or rice straw in weight is equivalent to grain
yield. Maize stover is 70-75% and
pineapple waste 60-80%. An enormous
amount of fibrous by-products from cereals and other crops is available each
year in many regions of the world. In
developing countries, where most farmers are rural smallholders, these crop
wastes and by-products are usually available in relatively small quantities at
the farm; hence, they are not economically marketable. Some of these crop wastes such as stubble and
stovers, are left over in the field, buffaloes eat these crop wastes and also
get rid of green weeds as well as dropping manure in the fields. These features are among the many complicated
and delicate interrelationship between crops and animals in sustainable
agricultural production systems on small farms in rural areas.
Buffaloes
raising as part of small-farm agricultural systems has positive effects on the
concept of social and economic sustainability, and consequently on rural
development. Buffaloes are usually looked
after by the women, old folks, and children, who are not employed
otherwise. Old folks in the rural family
feel that they are useful and needed when tending buffaloes. One of the major reasons for the rural people
who choose to remain at home during the dry season or do not go to work in
cities is that they have to look after their buffaloes or other livestock.
In the
mixed crop-livestock farming systems in rural areas such as that in
About
60-70% of buffaloes are raised by farmers in the Northeast (NE) region of
In most
parts of Thailand, especially the NE region, village farmers who generally
raise 2 to 5 buffaloes, usually set aside small plots of land of 0.2 to 1 ha
for ruminant grazing to supplement other sources of grazing areas available in
the village such as paddy fields. In
general, buffalo and cattle depend mainly on rice straw and stubble, while
other crop residues such as corn stalk, cassava and kenaf leaves, etc, also
provide substantial sources of roughage, especially during the dry season. No concentrate or other supplements are given
to bovine animals. Animals are generally
kept under the house during the night where they are more protected from
thieves. There are virtually no cash
inputs used and most tending is done by family labor including women, children
or old folks.
Health care
for buffalo is very minimal. Some may be
vaccinated against certain infectious diseases, but most are not. In general, farmers do not buy any medicine
to treat sick animals, preferring to use traditional curing methods practiced
since ancestral times.
Four to 6
metric tons of wet manure and urine can be obtained from a mature buffalo
annually. As most rural farmers cannot
afford to buy chemical fertilizer to use for paddy production, buffalo manure
has been used in the paddy field to sustain rice productivity. It is clearly evident that in the rain-fed
areas in spite of very little or no chemical fertilizer application, rice
production of 1.5 to 2.0 ton on average per hectare has been sustained since
time immemorial. This is due mainly to
the use of animal manure in paddy production by the village farmers. As far as the rural farmers are concerned the
use of chemical fertilizer is too expensive and too risky due to natural
hazards and uncertainties, such as drought, flood, or plant diseases and pests,
as well as fluctuating market price of paddy rice.
At least 36
million metric tons of rice straw and stubble are produced annually as a by
product from paddy production (Chantalakhana, 1988), buffaloes and cattle
utilize these residues for maintenance and growth. The utilization of straw and stubble requires
minimum labor since buffaloes are allowed to graze in the paddy field during
post-harvest season. While grazing in
the field, animals drop manure and urine to increase soil fertility. This is a very important aspect of small-farm
productivity. In short, buffaloes make
use of the non-marketable by-products, straw and stubble in this case, and
increase soil fertility through manure dropping.
Buffaloes are considered by rural farmers as long-term investments and a source of inheritance from one generation to the next. In general, village farmers do not go to the bank since they live in remote areas and, after all, they do not have excessive cash to deposit in the bank. What they earn in cash is barely sufficient for their subsistence. However, livestock is generally utilized by the farmers as a source of saving; chicken and pig are short-term savings while buffalo and cattle are long-term ones. In case of crop failures due to drought or flood, buffaloes or cattle will be sold in order to obtain sufficient cash income to purchase a rice supply for year-round family consumption. In the case of traditional ceremonies such as marriage or some religious rites, rural farmers will sell buffaloes for cash or slaughter for meat.
A case
report by the Thai Department of Livestock Development (DLD) on Pan-Rua
village,
Buffaloes are considered a companion and friend especially
to children and old folks in rural village.
Since only a small number of buffaloes are raised per village household,
the farmers take care of each animal individually and they call each of their
buffaloes by name. A name is usually
given to each buffalo instead of hot-brand identification. During school holidays, children often spend
all day tending and playing with their buffaloes. Children and buffaloes in rural farms grow up
together. Many village farmers would be
rather reluctant to leave their household for a long period of time because
they have to take care of their buffaloes and other livestock. In other words, it can be said that buffaloes
have a role to serve as a significant social factor in reducing the problem of
farm migration into big cities.
Often
buffaloes are used as tourist attractions in

It spite of
the contributions buffaloes have made to the rural farming systems buffaloes
remain more or less a neglected animal in relation to government and private
investment in buffalo production development.
This is due to the fact that buffaloes are animals which belong mostly
to poor developing nation, and trade of buffalo breeding stocks is of limited
interest of most developed countries where research and development funding and
supports are available for international scientists. In developing countries, almost all of the
buffaloes belong to resource-poor farmers who have little or no influence on
government or administrative decisions, while large government livestock
development programs are usually influenced by external assistance experts with
no interest in buffaloes and no real understanding of traditional small farmers
who usually have little or no education and easily influenced by government
policies carried out by local officials.
It is well
known that buffaloes under harsh conditions are capable of digesting fiber and
cellulose better than cattle (Sasaki 1994).
Buffaloes are much more productive when roughage feeds become scarce
during dry summer season since they require much less selective grazing, as
compared to cattle. But unfortunately

Why does
the buffalo population keep declining in
It is
interesting to note that in 1996 official statistics on the numbers of
slaughtered cattle and buffaloes were 597 thousands and 158 thousands,
respectively. While the annual statistic
of processed cattle and buffalo hide was 60,000 metric tons which could be
converted into the total number of cattle and buffalo slaughtered of
approximately 2 million heads (each animal produce at most 30 kg of hide). This indicates that at least 1.2 million
heads of slaughter cattle and buffalo were not included in the official
records. It can be expected that out of
1.2 million heads, the number of slaughter buffaloes was proportionately much
higher, judging from the rates of buffalo population decline each year. During the past few years increasing rates of
slaughter of pregnant and breedable buffalo cows have reached a critical level
which will bring this animal closer to extinction.
The decline
in buffalo number is partly related to increased use of small (two-wheel)
tractors in villages. The Thai
government supports mechanization in agricultural production by offering loan
credits to farmers for small tractor purchase through the government’s Bank of
Agriculture and Agricultural Cooperatives (BAAC). Figures in Table 3 show the results of a
monitoring study on the use of draught buffalo and small tractors in two
village cases in Surin province. Due to
BAAC loans as well as cash from sale of buffaloes the ratios of small tractors
for 1992 : 1988 was almost 5 : 1 in one village and 14 : 1 in another village. Some of these tractors, however, were
underutilized, while some were hire out since landholdings in these two
villages were only 3 and 2.6 ha per household.
Some of these farmers purchased small tractors just to be “fashionable”
like their neighbor, others were influenced by TV commercials of the tractor
manufacturers.
Needy
farmers also sold some of their buffaloes for cash. Other reasons were insufficient grazing
areas, lack of family labor for tending the animal, or a combination of these
problems.
The results
from the village study in Surin province during 1988-1992, partly shown in
table 3, showed that there were greater advantages of raising buffalo for
draught power by farmers in rain-fed lowland mixed farming systems. The buffalo has been used as a multi-purpose
animal by farmers, and most important of all it supports farming
sustainability, promotes rural equity and income earning, serves as assurance
for food security in time of natural calamities. Buffalo production offers and opportunity for
poverty reduction in rural areas where living conditions and resources such as
water and soil are less favorable such as that in Northeast Thailand. An analysis to compare the usefulness of
buffalo with small tractor is presented as following.

People
who have not worked very closely with village farmers and mixed farming systems
under rain-fed conditions such as that in Northeast Thailand may not understand
why most farmers keep both buffalo and cattle, as well as some pigs and
chickens on the same farm. There are
other reasons besides those already mentioned in the previous sections as rural
farmers recognize the complementary characteristics of buffalo and cattle, both
from biological and socio-economic aspects.
When buffalo and cattle are being raised in the same village
conditions under which management and feeding levels are minimal, their productive performances are
quite comparable. Farmers raise cattle
for sale while buffalo for draught power as well as for sale. Growth rates and meat qualities of buffalo
and Brahman cattle raised under the same environment are quite comparable, as
well as their reproductive efficiency.
The buffalo, due to wallowing, is much less susceptible to ticks than
Brahman cattle.
Buffaloes
are known as having fewer sweat glands on body skin than cattle and, hence,
they are expected to be less heat tolerant.
Buffaloes reduce heat stress by lying in mudholes or wallowing areas. Buffaloes sometimes make wallowing areas or
mudholes in pastures or near animal barns, which may create management
problem. However, in Thai villages where
rice production is common, wallowing areas around paddy fields are generally
available for buffalo. Buffalo wallowing
has not created environmental problems in rural areas.
An experiment was carried out at Kasetsart University in Thailand to compare fattening performances of buffaloes with dairy bull calves and Kamphaeng Saen (KPS) beef cattle. All animals were fed individually in feeding stalls, where management and feeding practices were all the same. Buffaloes were also kept in stalls without any wallowing. Comparative data on growth and cost of growing these animals are shown in Table 4. KPS beef (50% Charolais, 25% Brahman, 25% Thai breed) appeared to grow fastest, dairy beef (Holstein-Friesian>75%) the second, and buffalo the third. However, the cost of fattening per kg body weight was lowest for buffalo. Buffalo feeding appeared to be appropriate and profitable when the feeding level and feed quality were low. The results from this study showed that buffalo feeding in villages can be a viable enterprise since buffalo grows well on crop residues and by-products, especially at the present time when prices of buffalo are more or less the same as that for crossbred cattle.

Until today the buffaloes in Asia and Thailand are still
largely the animals of the village, they have been neglected and
underutilized. In Thailand most national
agencies and institutions have ignored and overlooked this animal. Government development programs in the past
have largely bypassed buffalo promotion, in favor of commercial livestock
prevailing in industrialized countries.
This bias must be corrected and fair development supports have to be
allocated for the promotion on buffalo raising and use by farmers in rural
areas. Some examples of possible
development activities are discussed as the following.
In Thailand as early as 1978 H.M. the King visited
Prachin Buri and learned of small farmers’ suffering due to the serious
shortage of work buffaloes for farming.
H.M. the King then initiated the first project called “Royal Initiated
Cattle-and-Buffalo Bank Project” to provide work animals for those target
farmers.
Usually, the word “bank” is understood as an
institute dealing with money. It may
confuse some people who have never heard of the Buffalo Banks before. His Majesty the King once described the
Buffalo Banks as the collection and distribution of buffaloes in order to help
those who do not have buffaloes for farming; it is not necessary to have the
buildings, it needs only an organizer to handle the collection and disribution
systematically.
The policy
of the Buffalo Banks does not aim at supplying buffalo free of chare; otherwise
there would be no need to set up the bank in the first place. This policy should be clear to everyone
involved. The farmer who needs a buffalo
from the Bank has to pay the Bank in some way depending on the regulations set
up by the Bank. This is to allow the
Bank to be able to carry on its operation with sufficient operating fund.
To help increase the small farmers’ income.
To allow the farmers to own buffaloes.
To lend out work buffaloes at low rental rates.
To promote the use of buffalo manure.
Some Banks may have the objectives other than what are already
mentioned. For example, the Office of
Accelerating Rural Development expects the Buffalo Banks as one way to organize
the farmers.
Up till now, there have been many different Buffalo Banks
throughout Thailand operated by different organizations, both government and
private. The Buffalo Banks can be
roughly classified as (1) Royal Initiated Project mainly operated by the DLD,
including also those projects in the Rural Poverty Alleviation Plan (NESDB,
1981), (2) other government projects, for instance provincial government
projects or the Office of Accdelerating Rural Development projects, and (3)
private organization project.
Although
there are many Buffalo Banks in operation but the basic objectives and services
fall more or less among the following.
Free lending.
The Bank may lend buffaloes to poor farmers free of charge. This is practiced only occasionally. In some areas the free lending is offered to
military veterans.
For breeding.
The Bank provides female buffaloes to those who want to own the
calves. The farmers are required to hand
in the first calf to the Bank and keep the second calf. Some Banks may take only the first female calf. The returned buffaloes and the calves will be
redistributed to other customers. Rules
and regulations may vary among different Banks.
For work. The
Bank may lend out the buffalo to qualified farmers (i.e., farmers who are poor,
do not have their own buffaloes, and have to pay high rent).
Lend-lease.
Those who want to own the buffaloes right away may obtain them from the
Bank if they are qualified. The
installment plan is arranged for the farmers, and no interest is charged. The period of the plan ranges from 3 to 5
years among various Banks.
In order to
restore the interest of the villagers in buffalo raising, government agencies
responsible for buffalo development need to take action to make the rural
farmers realize the important role of buffalo in rural farming, and to fully
utilize the buffalo in order to improve farm productivity and lower the cost of
production. There are villages
throughout the country, especially in the Northeast, where farmers are still
interested in buffalo raising. They
ought to be selected and promoted to serve as promotion centers for buffalo
conservation and development. These
villages should receive priority in husbandry and veterinary services from the
government agencies. In 2000 the DLD
initiated this project in 19 villages in 19 provinces in Northeast
Thailand. The major objectives of the
project are : (1) to encourage voluntary participation of rural farmers in
finding solutions to livestock production problems, (2) to reduce the decline
of village buffalo population, (3) to create awareness among farmers of the
importance of buffalo for the sustainability of the mixed crop-livestock
farming systems in the Northeast, (4) to make the village a center for
livestock technology transfer to farmers in other village, and (5) to promote
conservation and sustainable development of buffalo production. The 19 provinces, each with one village in
this project, are : Nakhon Ratchasima, Buriram, Surin, Si Sa Ket, Ubon
Ratchathani, Yasothon, Amnat Charoen, Roi Et, Chaiyaphum, Khon Kaen, Nong Bua
Lamphu, Mukdahan, Kalasin, Udon Thani, Sakon Nakhon, Nong Khai, Nakhon Phanom,
Loei, and Maha Sarakham.
In 2000 the
Department of Livestock Development organized an evaluation team to assess the
villages success in achieving the project objectives, and the three most
successful villages were given awards at the annual national buffalo
convention, these were:
Most Distinguished Award : Pan Rua village, Prasat
district, Surin province,
Second Award : Non Sawang village, Phu Viang district,
Khon Kaen province, and
Third Award : Kam Khon Ta village, Sai Moon district,
Yasothon province.
It is
generally known that buffaloes are a long-term savings and asset of rural
farmers. In case of urgent need of
money, for instance, in time of flood or drought or other natural calamities,
in case of marriage or children entering Bhuddist monkhood, purchase of
expensive items such as motorcycles or pick-up trucks, needy cash for other
investments such as application for overseas work, farmers usually have to
depend on the sale of buffaloes. Some
farmers sell buffalo cows because they need to buy fertilizer for crop
production. Sale of buffalo cows can be
prevented if a village buffalo emergency funds could be set up to offer emergency
loan by using breedable buffalo cows as a collateral. The farmers could obtain necessary cash at
half value of the buffalo cow, the value of a buffalo can be determined by a
certain committee. Farmer continue to
keep “pawned” buffalo cow and hopefully the farmer would be able to pay back
for the loan in the next year. If the
pawned cow produces a calf during the loan period, the calf should belong to
the farmer. This proposal should be able
to slow down the sale of village buffalo cows as well as increasing the number
of buffalo calves. The detail operation
procedures and the implementation of the village buffalo emergency funds could
be carried out by a local administration such as Tambon (Sub-district) Administrative
Organization (Ore Bore Toh), or a village committee, or other existing and
already highly respected bodies at grassroot level.
As has been
mentioned in previous section, some government policies, such as promotion of
farm mechanization, bias for promotion on beef cattle raising, lack of fair and
effective marketing systems for rural farmers, weak law enforcement concerning
illegal slaughter of buffalo, etc. have contributed to the decline in buffalo
population in Thailand during the last two decades. It is very important for the government
administrators to be fully aware of the serious possible extinction of the Thai
buffalo. It is also very important to
sensitize the general public, as well as the politicians to recognize the
importance of buffalo in rural economy and sustainable farming systems, and to
realize the grave situation contributing to the dangerous declining of this
valuable animal genetic resource.
It is also
very important that the government provide a clear policy and financial support
to public institutions to increase their activities concerning buffalo research
for development, to tourism and cultural organizations in promoting traditional
and cultural ceremonies and sports involving buffalo as a regular ago-touristic
attraction.
It is of
the utmost importance for international development or research organizations
to have clear understanding and unbiased information about the contributions of
buffaloes, considering all aspects including cultural and socio-economic
aspects which contribute to rural people and their economy. It is very important to create awareness and
to sensitize international development or technical personnel to appreciate the
value of buffaloes from the rural farmers’ view. Analytical studies should be carried out in
detail to show how the buffalo’s roles in sustainable agriculture, food
security, rural equity and asset building, and self-sufficiency economy as
promoted by HM the King of Thailand.
There is a
great need for regional and international organizations to promote buffalo
conservation and development in order to inform concerned national governments
and people how to make better use and careful management of this valuable
resource. Existing regional and world
associations, such as Asian Buffalo Association (ABA) or World Buffalo
Federation (WBF) ought to be strengthened so that they become more effective
and more dynamic in the promotion of buffalo development, international
collaboration, and information exchange among member countries. During the past these organizations played
only a limited role, i.e. organizing technical meetings once in every 2 to 4
year, due to lack of resources and national and international support.
