Evidence
suggests that Bos Taurus and Bos Indicus split
in two independent events the first being over
200,000 years ago and the second some 10,000
years ago. Essentially Taurine cattle were developed
in the Fertile Crescent region while the zebu
type was domesticated in the Indus Valley region.
(Scherf, 2000). Further details are provided
by Hall (2004).
Since
then, many breeds have been developed in both
sub-types so that there are now many taurine
types and many zebu types throughout the world.
The number and variation of the breeds is dependent
upon the definition of ‘breed’ as
well as on local activities.
FAO uses a definition which states “either
a subspecific group of domestic livestock with
definable and identifiable external characteristics
that enable it to be separated by visual appraisal
from other similarly defined groups within the
same species, or a group for which geographical
and/or cultural separation from phenotypically
similar groups has led to acceptance of its
separate identity. Note: Breeds have been developed
according to geographic and cultural differences,
and to meet human food and agricultural requirements.
In this sense, breed is not a technical term.
The differences, both visual and otherwise,
between breeds account for much of the diversity
associated with each domestic animal species.
Breed is often accepted as a cultural rather
than a technical term.” (Scherf, 2000).
The
two types have been developed over at least
10,000 years in different regions and environments
that, inevitably, have lead to different characteristics
and qualities. However, there is considerable
variation between breeds of the taurine type
as indeed there is between breeds of the zebu
type. While generalizations are useful they
can also be misleading if taken as the whole
story.
A useful summary of the differences can be found
in Cunningham and Syrstad (FAO 1987). ‘Most
of the cattle indigenous to the tropics belong
to the zebu species.’ They have a high
degree of heat tolerance, are partially resistant
to ticks and many tickborne diseases and have
low nutritional requirements. The authors go
on to point out that potential for milk production
is poorly developed in most zebu cattle and
that milk let-down is a problem. Zebu cattle
are late maturing too.
While in the Indian sub-continent has several
breeds for milk, many breeds for dual purpose
and many for draught purposes, in Africa most
zebu breeds have been developed for beef production
with some having good dual purpose abilities.
Evidence to support the generalizations is variable
but, in general, does provide sufficient evidence
to provide a good basis for discussion of the
implications. There is now much better evidence
from some major breed comparison trials such
as the USDA Breed Evaluation Research based
at Clay Centre and the CRC Beef research in
Australia. Evidence from the USA and from Australia
shows that breed type performance depends on
the environment and that rankings change in
the different environments (Cundiff, 2005; Arthur
et al (1999) and Olson et al 1991). Anderson
and Uquhart (1986) stated that animals with
zebu genes could range further than taurine
types in semi-arid rangelands in Mexico.
Hammond et al (1996) reported on heat tolerance
and that Brahman (zebu) had lower respiratory
rates, greater packed cell volume but poorer
temperament. Several contend that greater skin
area also contributes to the zebu heat tolerance
(e.g. Ghosh et al 2006). Godfrey et al (1991)
showed that Bos indicus calves exposed to cold
were more susceptible than Bos taurus calves.
Chakravarthi et al (2004) report both on the
additional surface area (about 12% over taurine
breeds) and on the Ongole skin secreting sebum
which acts as a fly repellent and filters the
sun’s UV rays.
Aggarwal and Singh (2006) reported Upper (UCT)
and Lower Critical Temperatures (LCT) for different
breed types –38ºC and 10ºC respectively
for Indigenous breeds, 24ºC and 2ºC
for Jersey and crosses, 20ºC and -10ºC
respectively for Holsteins. Ghosh at al (2006)
reports temperatures at which milk production
starts to reduce as 21ºC for Holsteins,
24/27ºC for Jersey and Brown Swiss and
32ºC for Zebu type.
A review by Thrift and Thrift (2003) reported
on the longevity of crossbreds in hot, humid
conditions and attributed it to the heat tolerance,
lower ecto and endo parasites, less eye disorders,
teeth deterioration and grass tetany from the
indicus component. He reported that the animals
had more udder and teat problems/abnormalities.
Frisch (1973) reported lower death rates in
Bos indicus cattle in central Queensland.
Several trials report that on the differences
in disease resistance – examples are Ndungu
et al (2005) on Theileria parva, Mwangi et al
(1998) on tick infestation, Aulakh et al (2005)
quotes Nerladker et al (1995) as showing that
symptoms of babesiosis are more marked in exotic
breeds. The CRC (2006) work in Australia confirms
tick resistance but also shows the poorer temperament
in Brahman cattle. In general, poorer temperament
means that animals grow slower (Voisinet et
al 1997)as well as possibly causing more difficulties
for management.
Clearly the generalizations do apply and have
consequences for management requirements but,
as an example of the danger of taking generalizations
as the whole story, the Brahman was imported
into Thailand in the early 1990s. In some areas
there was reference to the “plastic’
cow which, on further enquiry was the Brahman
which according to local farmers “Looked
good but produced nothing”. This was shown
to be due to the lower feed availability in
some areas since work in Texas has shown clearly
that the Brahman reduced reproduction if not
on full feed whereas the Nellore did not . Indeed
in that part of Thailand, the local White Lamphun
cattle reproduced normally on the feed available.
In Africa, there are now several taurine breeds
which have been developed to produce efficiently
in tropical conditions (see Jenkins and Farrell
2004).
While the general consensus is that zebu type
cattle can deal with poorer feeds better than
taurine cattle, there is little evidence to
show that they are inherently more efficient
(see Hall, 2004). Indeed there is little evidence
on feed efficiency beyond some work by Gibson
1986 showing the Holstein to be more efficient
than the Jersey for milk volume but there was
no difference in terms of milk energy produced.
Van Arendonk et al (1991) show a strong genetic
correlation between milk yield and the production/feed
intake ratio, which may reflect some measure
of efficiency. Thiessen et al (1985) show that
most of the genetic variation in efficiency
is within breed whereas for body weight the
reverse is true, which means that to improve
efficiency one should select within breed not
between breeds.
What has all this to do with managemental differences?
The evidence is sufficient to make it clear
that there are conditions under which certain
management practices will either be essential
or not necessary. Some of these practices will
impose permanent, repetitive annual costs which
add to costs of production and cannot easily
be reduced. The use of different breeds will
mean that, in certain environments, such costs
can be avoided.
As reported by Gandhi and Singh (2006), the
2003 census in India showed that there are some
179 million cattle of which 69 million are breedable
cows and about 7 million are crossbred. Notwithstanding
the increase in total numbers, cattle are now
42.7% of total livestock whereas 30 years ago
they were 50.4% - Buffalo have risen from 16.3%
to 18.3% but produce 55% of the milk whereas
cattle produce about 40% (24% from indigenous
and 16% from crossbreds).
FAO (2006) reports an estimate of 1493.5 thousand
metric tons for 2005 for beef and veal and 1487.6
thousand metric tons for buffalo meat. While
the dairy industry is the key to cattle production,
beef and veal constitute 26% of the meat production
recorded in India – a figure similar to
that for buffalo (25%). However the authors
(Anantham et al 2006) comment on the inexplicable
low contribution of sheep and goat meat(12%)
relative to the live population (30%) and suggest
that slaughter of these animals may not be fully
recorded in rural areas. Clearly, the section
of the population which eats beef and veal cannot
be ignored and may well offer assistance to
the future for those breeds traditionally used
for draught purposes.
Table 2.11 from Falvey and Chantalakhana (1999)
by de Jong (1996) shows the structure of the
dairy industry but does not indicate the proportion
of buffaloes.

Ananthram et al (2006) reports on structure,
classifying 81% of holdings as Small (with 0.74
hectares), 12% as Medium (2.96 hectares) and
7% as Large (aver 6.50 hectares) and points
out that the Small farms are grossly overstocked
relative to land holding. They also comment
that more efficient production from Common Property
Land could do much to reduce the feed deficit
as could better use of good indigenous dairy
breeds and crosses.
Potential
problems?
Herd size is very small but this is really little
different from the situation in Europe in the
not too distant past – indeed in some
parts of Europe herds are still relatively small
(10 cows – even beef herds in UK some
15 years ago averaged this). However land area
is smaller and, therefore, feed availability
needs better planning but in a situation where
farmers are less well educated and have less
resources. Herd size is reported to increase
in India [Rao (2005) quoting Conroy] and this
is likely to be the trend. However, it is to
be hoped that the normal arguments of economies
of scale are treated with considerably more
suspicion than in the past. For example, Dr
(Miss) Amrita Patel at the Dairy Industry Conference
in 2005 (see Indian Dairyman 57:12) showed that
the ‘Gini’ factor for dairying was
0.11 compared to 0.86 for crops. This demonstrates
clearly the more equitable sharing that dairy
production gives to society. At the same conference,
Dr Trevedi emphasized the local breeds advantages
in resistance, ability to survive and to perform
on poor feeds and fodder and with poor management
and Dr Misra identified the problem as being
large deficits of Green fodder (56%) and Concentrate(30%).
Interestingly Dr (Miss) Amrita Patel at the
All India Dairy Industry Conference in 2006
commented that the yield of crossbreds was reducing
now due to indiscriminate crossing and lack
of consideration of the agro-climatic conditions
and that the use of selected local dairy breeds
needed to be improved rather than the use of
exotic breeds and farmers should be better educated
about this matter by the extension services.
A paper by Kumarvelan and Obireddy (2006) described
how farmers in Tamil Nadu were changing back
to Tharparkar from crossbreds due to the high
veterinary bills and other inputs and the infertility
of the crosses and were now receiving a premium
in local towns for their milk.
Two other points could be made regarding crossing
– Cunningham (Balaine, 1979) pointed out
that ‘there is a great danger that many
local populations of cattle , with great potential
for the future, will simply be obliterated by
top crossing with these developed strains’
after pointing out that the European populations
were unimproved and unproductive just a few
generations ago. He advised that the local breeds
be selected as a matter of urgency. Cunningham
and Syrstad (1987) point out that criss-crossing
two breeds can yield better than forming a synthetic
of the same two breeds – if there is no
need to progeny test one of the breeds then
it clearly can be more cost effective in terms
of milk production. Rege (1998) is an example
of many reports showing that, in general, the
first cross indicus x taurus dairy animal is
rarely bettered.
The number of local breeds depends on the definition
used officially but is around thirty –
many of these can be regarded as dual purpose
or dairy breeds but the breeds specifically
developed for draught purposes are now under
greater pressure as the need is reduced due
to mechanization. Whether such mechanization
is justified is not part of this paper but certainly
the problem is one which needs to be addressed.
Kumar and Dixit (2006) reporting on the decline
of the Hariana state that the lack of market
for male calves, the shortage of grazing areas
and the attraction of the buffalo, which has
no limitations on markets, all contribute to
the breed’s demise. This is a problem
which, in terms of animal genetic resources,
needs addressing at the highest levels.
The
number of local breeds could well be much more
than officially noted – particularly if
the FAO definition is used. Many of the ‘non-descript’
populations may well be pure breeds but due
to the colonial influence the old, incorrect
view of breeds still seems to hold sway. From
my previous experience within India, it is obvious
that Goshalas can play a major role in the improvement
and development of indigenous breeds –
indeed some are already doing so. Cooperation
between Goshalas could provide sufficiently
large populations to make significant genetic
change, to avoid inbreeding and to provide animals
and genetic material to farmers in need.
Future Management
Speedy and Sansoucy (1991) edited an FAO publication
Animal Production and Health Paper No 86 (reporting
proceeding of an expert consultation in late
1989) which contains comments regarding the
“greenhouse effect’ and its implications
– now accepted as Global Warming and Climate
Change – Preston quoted Dupont (1989).
Preston discussed the goals and means for both
industrialized and developing systems and quoted
the Netherlands Development Corporation which
had been trying to introduce innovations into
developing countries “The animals (Dutch
dairy cattle) were generally unable to adjust
to local conditions; climate feed and management
systems all posed problems. The cattle were
unsuited to small farmers’ needs;…”
and “the experience of twenty years revealed
that the route (intensive livestock projects)
had been ill-chosen.”
Preston then summarized what he believed were
the requirements of a system:
· “be at least self –sufficient
in, and preferably a net exporter of, energy
· not contaminate the environment
· not destroy natural ecosystems
· optimize employment opportunities,
and
· promote a maximum degree of self-reliance”
There is nothing in these objectives which does
not apply now – perhaps the urgency is
even greater now after almost twenty years.
At the same consultation, Leng discusses in
detail the use of techniques to improve nutritional
efficiency in the ruminant – again the
same points that are just as valid today –
“The efficiency of feed utilization is
enormously improved if the rumen of the animal
has a healthy microbial population adequately
supplemented by providing a molasses/urea block
which often increase the intake of the basal
diet. Adding a by-pass protein supplement will
further improve the efficiency of utilization
of the basal feed resources but will also allow
animals to maintain feed intake at high temperatures
and humidity. Conversely, the productivity of
lactating animals can be maintained at a lower
feed intake provided the rumen is made efficient
and the animal’s metabolism is made efficient
by supplementing with a molasses/urea block
and by-pass protein respectively.” Again,
this is as true now as it was in 1989.
It
is absolutely crucial that the type of animal
must be suitable for the local agro-climatic
conditions. Evidence shows that size of animal
is not genetically linked to milk yield (at
least in Holsteins – Hansen et al 1998)
and that large size means additional feed for
maintenance. Clearly there is not a single solution
for India given its vast range of agro-climatic
conditions but the ability of indigenous breeds
to withstand heat cannot be ignored since the
costs to keep animals sufficiently cool is permanent
and likely to increase. Thailand is a classis
case where milk price is high but farmers cannot
make profit due to the additional costs to maintain
a suitable environment for the cows in use.
Disease resistance and tick tolerance must also
come into the picture – even the choice
between Jersey and Holstein can affect this
particular problem. However since the Holstein
is more efficient for milk volume, the Jersey
needs a situation in which milk quality is rewarded.
Obviously the reduction in veterinary treatments
can be important but not at the expense of using
the essential treatments to avoid major difficulties
such as vaccinations so that indigenous breeds
still need careful management.
Clearly the ability of indigenous breeds to
use poorer types of fodder can be used in management
decisions. However it is crucial to be aware
that poorer fodder will not provide adequate
nutrition for milk production. It is therefore
essential that the other feeds are used in the
most advantageous manner if the animal is to
use low quality fodder. There is no excuse for
not using straw treatment neither for the lack
of molasses/urea /mineral blocks. Even though
straw treatment is time consuming and most small
farmers (especially the ladies) have no spare
time, the policy adopted in parts of China might
well be adopted – they have one person
in a community who treats all the straw farmers
deliver straw and collect the treated product
for a small fee. The cooperative systems in
India are ideal for such arrangements and may
already be used but this author is not aware
of examples. One major factor in India’s
favour is that most of the animal feed is non-human
feed which is in stark contrast to several other
countries with large cattle populations –
the most obvious example being the USA which
uses vast amounts of human feed (maize) in cattle
feed-lots and dairy herds.
The techniques for improving rumen efficiency
and reducing methane production hold out hope
for the future – as long as they can be
made available at an economic price to the people
who need them most – the users of low
quality roughages. However, all efforts at present
should address the present well known techniques
to assist good rumen efficiency – the
simple molasses/urea block.
The use of bypass protein is advocated and,
indeed, assisted by the major cooperative organizations
but this should be a universal policy across
the country. The evidence is overwhelming and
the process is cost effective. Protein is too
valuable to be wasted – it is a bad as
throwing money down the drain – in fact
worse because the protein may cause pollution
of the water system as well!
Pollution can be as serious in small units as
in large ones – it all depends on the
management system and the density of the farms.
Many small farms with little land and overstocked
can provide a real pollution problem. Given
the rising costs of energy and the climate change
effects, it is crucial that the industry gears
itself up for a future where energy is used
more efficiently and air and water pollution
is reduced since it has to be paid for (if not
directly, then indirectly). Animal wastes should
be used to provide energy (it often is and India
has a good record in this respect) and to ensure
soil quality. There is growing evidence that
the reliance on chemical fertilizer alone is
providing problems for the future and a better
balance must be achieved. In small herds, it
may be possible to use the waste from the biogas
process on Common Property Lands in an effort
to improve fodder availability.
There is an expectation that herd size will
increase and this is probably correct. However,
the lessons of the past should be carefully
noted – most economists basically had
extremely limited vision and their calculations
frequently ignored many of the crucial factors
in the complete picture. The number of cases
where ‘externalisations’ are not
properly costed is legion and, in the view of
the author, is irresponsible. Such calculations
have lead to many incorrect policies and the
world can no longer ignore full costing of all
activities.
The costs of dealing with soil degradation due
to ‘mining’ i.e. the crop being
removed a long distance and no part thereof
or manure being returned to the land is rarely
if ever mentioned. This aspect must be considered
in the transfer of feeds to cover deficits in
various regions in India. Two classic examples
are (1) manioc(cassava) from Thailand to the
Netherlands to feed pigs and the manure to the
rivers and/or North Sea with the reduced growing
abilities of land in Thailand; and (2) the feed
movement to the Buffalo colonies near Karachi.
Pollution of waterways is often ignored although
awareness is growing – even where there
are regulations governing the release of water
into waterways there are still cots involved
in making it suitable for human consumption
(the cost of water treatment in UK is over $100
per hectare – Steinfeld, pers. comm.).
There are now many economists who question the
real benefits of ‘economies of scale’
(e.g. Schumaker 1973, Falvey 2000) – perhaps
the only real supporters nowadays are the large
international supermarket chains. India has
probably the greatest experience of using small
farms for production of a major product with
Operation Flood and all the associated activities
since then. While small herds may get larger
as they use their resources more efficiently
there is no reason for moving from the present
successful social model which reflects the famous
statement by Mahatma Gandhi that ‘production
should be by the masses not by mass production’.
There is therefore nothing in the principles
of management which should differentiate between
Bos Indicus and Bos Taurus – management
should aim to utilize the resources available
in the most efficient and sustainable manner
in the specific agro-ecological situation relevant
t the farmer and to the community. In addition,
management must aim to provide the most hygienic
and safe product possible for the consumer.
Recent developments in regulatory mechanisms
should help in this respect both in terms of
processing by the application of the Hazard
Analysis and Critical Control Point (HACCP)
system and, on farm, by the Good Animal Husbandry
Practices (GAHP) as reported by Rajorhia (2006)
who comments that awareness of the latter is
low among milk producers.
• Given that a safe product is essential
for all markets, it is even more important that
the whole system is such that it can be used
as an aid to marketing of products both at home
and abroad. In this respect, I see an additional
role for Goshalas in helping local farmers develop
products according to the requirements for safe
food production. Patil (2005) points out that
the potential market overseas is of high value
(North America is valued at $500 million). Given
that the richer nations are now becoming more
conscious of the whole process of food production
and are more aware of ethical, welfare and poverty
issues, it is crucial that the Indian industry
ensures that the local small farmer industry
can exploit such preferences. The welfare issue
is now of considerable importance in Europe
and has changed management practices even where
there is no evidence that the animals did not
like the practice. In fact, in the UK a series
of five freedoms has been developed by the Royal
Society for the Prevention of Cruelty to Animals
(RSPCA) in 1995. These are:
a) Freedom from hunger & thirst by ready
access to fresh water and a diet to maintain
full health and vigour.
b) Freedom from discomfort by providing an appropriate
environment including shelter and a comfortable
resting area.
c) Freedom from pain, injury or disease by prevention
or rapid diagnosis and treatment.
d) Freedom from fear and distress by ensuring
conditions and treatment which avoid mental
suffering.
e) Freedom to express normal behaviour by providing
sufficient space, proper facilities and company
of animals of their own kind.
The problems clearly are not in the knowledge
of what is required technically but are more
likely to rest with the lack of sufficient and
high quality extension. There are obviously
good extension people serving many communities
and many organizations attempting to help. Nevertheless,
it is still the case that researchers are regarded
as being ‘better’ than extension
people – academics have greater kudos
than the local farm adviser. However, little
research is really essential for improving the
farm production efficiency of milk – the
technical knowledge is available but not necessarily
applied. It is important that the extension
adviser is regarded as the key to the future
of the dairy industry in India and that the
importance of this role is fully recognized
in all respects. The good adviser is not someone
who is not good enough to do research (a view
often held in Asia) nor is he/she lacking in
ability – the abilities are different
and are crucial to the long-term future of the
industry. It mat well be possible that the Goshalas
can also assist by education and demonstration
and local advice as long as they use similar
management systems as those used by local farmers.
This should be the case since maintaining breeds
also requires consideration of the normal management
system.
As mentioned earlier, even within the last few
months, one of the most important persons in
your dairy industry, pointed out the same need
for better extension and education of the small
farmer. It is crucial that the quality and status
of the extension worker is properly considered
– to this end it may be necessary to have
a system of recognition similar to that in academia.
Certainly in Britain, for example, the extension
adviser can and does become an elected Fellow
of the Institute of Biology (recognized by royal
charter) just as the academic researcher but
obviously for the application of technology
rather than for research. When considering buying/selling
a house, the advice is that there are three
crucial factors – location, location,
location. In the context of a good future for
your cattle industry there are three crucial
factors – extension, extension, extension.
Given the present realization of the need for
such improvement and the organizational abilities
and experience in the country, then it is likely
that this situation will be resolved and management
levels will be improved and added value markets
exploited to enable more efficient use of local
resources and the continued success of indigenous
cattle in India.
