Abstract

Camels were originally domesticated for their milk. Following the move to use the camel as a beast of burden especially for armies, there has been a return to its original task. Camel is no more the animal of the old world, but an animal which may be use to combat the growing desertification and to feed millions of people living in those areas. There are many scientific data concerning the anatomy, physiology and endocrinology of lactation in camels. It has been shown that camels can provide 15-20 liters of milk per day for a lactation period of up to 18 months, ma'K.ingi\ a very good farm animal. The camel produces in harsh and hostile conditions where other animal may not survive. Studies conducted in the horn of Africa revealed that the camel produced more milk than the other types of tropical animals compared on the basis of kgfTLU/year. Camel milk is now used in the modern urban masses and found in the shelf of the super markets and shopping malls in the form of plain and flavored milk, cheese and chocolate. Globally camel produces about 2 % of the world total milk and that milk is mostly produced by pastoral people and consumed locally.

INTRODUCTION
r,
"
The camel has been serving milli9ns of people living in
the arid, semi arid and desert areas of world. It
provides food, fiber, transportation and social status to
the herders. A few attempts have been done in health,
nutrition,physiology and reproduction, camel
productivity per se is still relatively untouched. A lesser
and even neglected amount of milk is published in the
gray records,of the country. The camel milk has never
been appreciated, valued and estimated properly
(Younas and Iqbal, 2001). Importance of this specie
demands that separate estimates should be collected
to fully realize the exact potentials of camel as milch
animal and to place camel where it needs to be. This
will further help the scientists to suggest the
significance of camel in the changing global scenario
and to proper develop and manage the niche that
harbor this specie.
Camel possesses certain physiological features that
enable him to thrive in extremely arid environment.
Dromedaries use water economically in almost all
metabolic functions. The body temperature of the
animal can fluctuate between 93Qand 105QF;
therefore, sweating is reduced. They don't over heat,
can withstand water loss, and store fats in the hump for
use in times of food and water deprivation
Camel is a quality and variety browser. If the good
quality forage is not available, the camel then can
efficiently utilize poor quality forage with higher crude
fiber, more than the other herbivores, by increasing the
retention time of the fiber in the fore stomach for longer
time up to 74 hours. On the other hand, if feeding on
low-protein forages can recycle and utilize body urea
for microbial protein synthesis much more efficiently
than the true ruminant (Schwartz and Dioli, 1992). By
virtue of these attributes and potentials, the role' of
camel as food animal is being accepted globally and
the camel scientists (Faye and Esenov, 2005) state
that camel has unfathomed potential for satisfying
human's future dietary and medical needs.

Raziq, Younas and Kakar
Camel milk production is stable in almost all seasons,
which is very important for the pastoralist, when the
milk of other animals is seized in the dry period. As
camel intake per kg of milk produced is very less, it will
be suitable specie to be maintained even on marginal
and poor grazing lands. According to some reports,
camels need only 1.9 kg of dry matter to produce a liter
of milk, compared with 9.1 kg for cows (Stiles, 1983).
Therefore a review study of the available information
on the ability of camel as milch animal was conducted
to know the actual worth and future role of camel as
dairy animal.
CAMEL GENETIC BIODIVERSITY
Camel posses vide genetic biodiversity and there are
many breeds of camel in the arid and semi-arid areas
of the world. Each breed has been developed by their
own perspective pastoralist community for their own
breeding goals. Some camel breeds were developed
for the work hence they are good draught animals. The
camel evolved for the long traveling in the desert in
caravans are now good race animals. Some other
breeds were developed for the food production
especially milk in the harsh environment and now
these breeds are good milch animals
Table 1. Production potential of Pakistani camel
have been reported first time by Raziq and Younas
(2006).
MILK PRODUCTION
Camel was originally domesticated for milk. God gifted
cow camel to Prophet Saleh some 3500 Be back to
drink the milk only. The camel's milk was a gift from
God for the Arab Bedouins. In the Holy Quraan the true
worth of the camel has been described. According to
Khan (1974), the desert dwellers when turned to God
in complaint about the climate and lack of food, God
heard their pleas and came to their aid; "He sent them
the she camel to drink her milk and they became well".
Pakistani camel has excellent potential as milch animal
including, Marecha, which is probably the best milk
yielder in the world with an average milk yield of 4,179
liters per year (Sial, 1950). On average daily milk yield
is from 8 to 10 liters but under intensive management
conditions milk yield is from 15 to 20 liters daily.
However, some specimens have been reported to yield
as high as 40 liters per day (Qureshi, 1986).
Experimental studies carried out in Pakistan on its
different aspects of milk and its products are scarce.
However, results of some studies are given in the

Earlier workers (Qureshi, 1986) narrated 4 breeds
(Bagri, Brela, Marecha and Mountain camels) in
Pakistan, stating that Marecha was the best milk
producer. Isani and Baloch (2000) have listed about 21
breeds of camels in the country. They have classified
them according to their habitats, production pattern,
body measurements, physiological norms and their
particular characteristics. An update of the breeds of
camel has also been mentioned. White camels (Kohi)
reported that the average milk production of Pakistani
camel was 1894.93 liters per lactation, with the daily
yield of 4.25 liter. This figure indicates the variability in
the production potential of different camel breeds.
Different breeds having different vigor, under different
ecological conditions for different traits provide plenty
of scope of improvement in camel potentials.
Camel milk is an essential diet of nomads in the desert
areas. Camel milk is sold in the nearby cities. Some
herders sell camel milk as pure, while others mix with
milk of cattle and buttalo, especially in the peak

season, when the milk production of other animals go
down. The milk yield although varies under different
production systems and nutritional management
regimes, an elite female camel may yield up to 10-15
liters daily on an average and thus may do extremely
well than exotic cow in tropical environment in its
Recent studies conducted on the milk production
potential on Kohi camel of northeastern Balochistan
proved that the mountainous camel produces an
appreciable amount of milk. Table 2 indicates the
potential of Kohi camel under the ordinary grazing
system on the rangelands.

performance as dairy animal. When the camels were
well fed, there was an average milk yield of 10-15 kg
per day (Yasin and Wahid, 1957). In the areas with
poor feeding and under desert conditions, the daily
average was 4 kg. Contrary to cattle, average daily
yield maintains up to at least 1 year provided fodder
andfeed are adequate.
According to some researchers (Knoess et ai, 1986),
camels produced more milk per kg body weight than
Sahiwal cattle, FriesianxSahiwal cattle and buffaloes.
Also in a similar environment, camels produce more
milk for a longer period of time than any other species,
while their requirement for feed is modest (Wilson,
1998). It was further reported by Knoess and his co-
workers (1986) that in Punjab, well-fed dromedary
camels produced more milk than even high-merit
exotic cattle and their crosses. They thrive in areas
where green fodder is only seasonally available as a
result of erratic rainfall,and can survive on feeds left by
other animals (Knoess, 1977 and Yagil, 1994). The
efficiency of the camel should be appreciated in terms
of its productivity parameter as well as with respect to
its superb adaptation to a harsh environment,
sustainability of production across seasons, and
accessibility to people living on marginal lands. The
milk production and the economic benefits of camel
milk were explored by (Jasra and Aujla, 1998). They
reportedthat the economic benefits of camel products
(milk, meat, etc.) are not apparently visible. However,
the domestic value is considerable. As high as 22 liters
of milk were daily obtained from a few she camels in
Balochistan. They reported that the daily milk yields
varied from 4 to 12 liters, the lower milk yields
attributedto poor feed supplies.
LACT ATION LENGTH
Lactation.length of she camel depends upon various
factors and varies from 9 to 18 months (Qureshi,
1986). The mainly available food item for the
pastoralists is the milk of she-camel; therefore, they do
not dry the animal, which results in the lengthy
lactation period, even higher than 18 months. However
according to some researchers, the milk yield and
lactation length of Pakistani camel averaged 1894.93
liters and 445.58 days (15 months), respectively
(Baloch, 2001). Farmers reported a lactation length of
270 to 525 days (9-18 months) with a the total milk
yield ranging in between 1,250 to 3,650 liters with an
average of 1,800 liters per lactation (Jasra and Aujla,
1998). The authors (Raziq, 2004) have observed that
the causes for different length of lactation probably are
due to the breeders control, fluctuations in vegetation,
long prevailed drought in the last decade (1996-2002)
and poor managemental practices of different areas. In
northeastern Balochistan the lactation length is bein~
controlled by the herders and dries the cow at the 8-9
month of lactation. This practice is done to harvest
more calves in the life span of the cow. The lactation
length of Kohi camel is presented in Table 2.
MILKING PATTERN
The mainstay of a nomad's food is camel milk. It is
consumed fresh or soured. In the northeastern
mountainous area of Balochistan, both regular milking
of two times daily and milking when needed, both
265
Raziq, Younas and Kakar
systems are practiced simultaneously (Raziq, 2004).
According to Jasra and AUjla, (1998), she camel was
milkedtwicea day,while young calves were weaned at
an age of 9 to
11
months. The camels are milked twice
in 24 hrs but 4 times milking is also not uncommon.
The camelhasa uniquecapability that it can be milked
any time during 24 hrs and six times milking has also
been noticed in some animals (Qureshi, 1986), that
excited many workers to initiate some studies on the
hormonal profile of this specie and the letdown
mechanism.
CAMELS MILK PRODUCTS
A wide range of products are made from camel's milk
such as various sour milks, cheese (kurth), khoa,
butter and ghee, etc. Despite common belief in south
Asia that camel milk cannot be used to prepare butter
and ghee due to the small diameter of fat globules,
some local and foreign workers have devised methods
to make butter and ghee successfully (Sial, 1950;
Qureshi, 1986and Knoess et al. 1986). Most common
milk productsmade from camel milk are dahi (yoghurt),
lassi (sour milk) and kurth (cheese) in northeastern
Balochistanhabitats.
There was a general belief that butter couldn't be made
out of camel's milk. But for the first time in the history
of Livestock and Dairy Development Department
Punjab, 175 gm of butter out of 4 liters of milk was
obtained (Qureshi, 1986). The detailed procedure has
been detailed out and further narrated by the authors
(Younas and Raziq, 2005). The Kurth is a name given
to local cheese,white in color, which is a hard rounded
piece of the dry matter of whey. Camel lassi is sieved
through muslin cloth, total solids are filtered and some
salt is added for taste development and further
preservation. It is further dried in the sun to make hard
balls. It is used as such or again changed into lassi
when needed. The lassi of kutrh is also used for
making a dish (The Kurtho Marrie). The pieces of
bread are soaked with kurth solution and then eaten
after pouring the desi ghee on it (Raziq, 2004).
EPILOGUE
The camel could not get much desired attention due to
many reasons and lack of awareness about its
attributes relating to its milk production and its
products. Due to prevailing droughts and decreasing
production trend of other animals, the camel has
gained much attention to abridge the gap of demand
and supply. The decreasing population of the camel
demands that factors contributing towards its decline
need to be taken care of. The recent studies have
shown that the camel is a big candidate, which can
meet the milk requirements of the pastoral people and
as well as other population if managed, bred and fed
properly. Furthermore in the changing and global
warming scenario, under-exploited species like camel
will find a better place to thrive and produce even
under harsh climatic conditions. A lot of virgin areas of
research and development in this specie demand, that
proper milk recording, selection and breeding practices
are to be taken to exploit its genetic potentials to its
maximum. Some planned and integrated efforts are
needed in camel concentration areas of Cholistan and
Balochistan to undertake research and auxiliary
developments on this specie and its allied disciplines. It
is expected to bring revolutionary changes and further
improvements in enhanced milk production to put smile
on the faces of the camel herders by improving their
pastoral economy.

Lactation is a physiological state that has been shown to modify protein metabolism in camels. Few data are available concerning the changes in protein fractions in lactating camels. This study aimed to investigate the effect of lactation on serum protein fractions in camels. Thirty (30) apparently healthy lactating Arabian camels (age 8–12 years, body weight 600–700 kg, parity 2–3). The animals were divided to three equal groups (10 each), as early lactation (< 90 days after parturition), mid-lactation (91–180 days), and late lactation (≥ 181 days). Blood samples were collected by jugular venipuncture, and serum harvested was used to determine total protein concentration ([TP]) and serum protein fractions using capillary electrophoresis technique. ANOVA (Levine’s and post hoc tests) were used to assess the difference between the groups. Lactating camels showed electrophoretic pattern composed of albumin, α1, α2, β1, β2, and γ-globulins. Serum-[TP] decreased (P ≤ 0.05) during early and mid-lactation to 67.10 and 65.15 g/l, respectively, compared to late lactation (72.31 g/l). The relative (%) and the absolute (g/l) concentrations of albumin, α1, and α2 fractions and A/G ratio showed no significant differences, while β1 and β2 decreased (P < 0.05) during early lactation (6.62%, 4.40 g/l) and mid-lactation (4.58%, 2.92 g/l) compared to mid (10% and 6.42 g/l) and late lactation (9.90%7.20 g/l), respectively. The γ-globulins increased (P < 0.01) during early lactation (21.08% and 14 g/l) compared to mid-lactation (12.40% and 8.12 g/l); however, it decreased (P < 0.05) during mid-lactation compared to late lactation (18.38% and 13.33 g/l). Capillary electrophoresis had been successfully used to assess and interpret the serum protein patterns during early, mid, and late lactations in camels. The results provided baseline data for dairy camel, which could be useful for researchers, veterinary practitioners, and those who work in the field of animal nutrition.
... In Ethiopia camel production management practices is basically traditional and the pastoralist only practiced extensive production system with no improved forage production for milk, meat and draft purpose (Eyasu, 2009;Yosef et al., 2014;Yohannes et al., 2015). Camels are interesting as a biological model for food supply in remote areas, combat the growing desertification and attaining food security of millions of people (Bernard, 2008;Raziq et al., 2008). In addition to this, camels almost have no competition for feed with other livestock, as they are hardy, comparatively eat less, sleep for short intervals and have a lifelong memory (Khan et al., 2003) and also, they survive with no water unbelievable period of time and tolerate expansion of bush encroachment of this fragile areas. ...

Camels represent a valuable source of roles for the pastoralist and adapted to the local environmental condition and selection pressure. Camels play many socio-economic key roles in traditional festivals and other customs, food security, income sources, as gift payment and serve as an important source of animal protein for pastoral communities in the country. It is therefore important due to the valuable traits of camel such as adaptation to harsh environment and ability to consume low energy feed. The characteristics have a significant contribution in performing sustainability in arid and semi-arid production system. The degree of women involvement relative to men in husbandry practice of camel is low rather than caring of calf, sick animal near the homestead aeras and sometimes selling of milk and its by product. Camel milk is unique in terms of curing different diseases traditionally such as jaundice, tuberculosis, asthma, diarrhea, constipation, respiratory disease and some viral diseases. Camels fulfill many communities need that are cultural, economic and social. However, the contribution of camel at the national level is not that much prominence. Thus, detailed information is need to develop appropriate intervention in strengthen the productivity of camel in the country.
... Whereas different livestock species have different climate resilience and tolerances [40][41][42][43][44][45][46] , location-specific data are required to assess where shifts in herd composition from currently cattle-dominated systems are needed to maintain or even increase dairy production in semi-arid and arid systems under climate change. Therefore, the aims of this study are (1) to assess where in the drylands of NSSA these shifts in herd composition are most likely to occur as an adaptive response to changes in climatic and biophysical conditions, and (2) to determine the possible impact of shifting dairy production from cattle to more climate-resilient goats and camels, in terms of aggregate milk production and environmental sustainability. ...

Climate change is increasingly putting milk production from cattle-based dairy systems in north sub-Saharan Africa (NSSA) under stress, threatening livelihoods and food security. Here we combine livestock heat stress frequency, dry matter feed production and water accessibility data to understand where environmental changes in NSSA’s drylands are jeopardizing cattle milk production. We show that environmental conditions worsened for ∼17% of the study area. Increasing goat and camel populations by ∼14% (∼7.7 million) and ∼10% (∼1.2 million), respectively, while reducing the dairy cattle population by ∼24% (∼5.9 million), could result in ∼0.14 Mt (+5.7%) higher milk production, lower water (−1,683.6 million m³, −15.3%) and feed resource (−404.3 Mt, −11.2%) demand—and lower dairy emissions by ∼1,224.6 MtCO2e (−7.9%). Shifting herd composition from cattle towards the inclusion of, or replacement with, goats and camels can secure milk production and support NSSA’s dairy production resilience against climate change.
... These unique properties also contribute for the product diversity and cater variations in consumer preferences (Balthazar et al., 2018;Ranadheera et al., 2016). Unequivocally, camel can produce milk and sustain its productivity in harsh and hostile conditions where other animals may not survive (Raziq, 2008). As detailed in earlier chapters, camel milk proteins are hypoallergenic and possess potential antimicrobial and protective activities, milk has low fat content with smaller fat globules and higher concentrations of useful polyunsaturated fatty acids, a high vitamin (especially C, B1), minerals (Mg, K, Na, Fe, Zn, Cu, Mn) and immunoglobulin content. ...

Nanobodies are highly versatile tools with interesting biochemical properties, which result in their application in various fields ranging from basic research and diagnostics to therapy. Since their discovery nanobodies have shown a high therapeutic potential and form an ideal stepping stone to drug development. We believe that effects triggered by nanobodies in vitro or in vivo are a faithful representation of what to expect with conventional pharmacological drugs, since both compounds directly target the resident endogenous protein. Furthermore, nanobodies have a lot to offer as a research tool. They can help researchers to elucidate protein functions and thereby gain insight in biological pathways. Several strategies are possible, ranging from subcellular delocalization to the induction of protein knockouts. Last but not least, nanobodies may represent an adequate answer to problems encountered with (conventional) antibody reproducibility. Further research has shown that fusing nanobodies to serum albumin, an abundant transport protein found in blood, significantly increases the half-lives of nanobodies, allowing them to remain in the blood for longer and in larger quantities. The immunogenicity of nanobodies can be reduced via humanization, a process that modifies some of the nanobody protein sequences to increase their similarity to human antibodies, reducing the risk of a negative immune reaction. Camelid nanobodies have not only proven their worth but could also change the landscape of antibody therapy and hail in a new generation of therapeutics.

The interactions of the camel with its environment is somewhat complex compared to other animal species domesticated by human. Camel can valorize the remote areas of the world, thanks to its wide production and services to human. The arid lands occupy more than 35% of terrestrial surface, and camel keeping in such areas is a blessing for the inhabitant rural communities. Camel production and products can support the participation of the stakeholders living in the desert or desert margins (in the peri-urban areas). Thus, it contributes to the global economy by its progressive integration to regional or international market. This book provides the reader with a comprehensive review on camel milk composition, physical, chemical, nutritional, dairy preservation and therapeutic properties and up-to-date potential therapeutic and nutraceutical benefits of camel milk compared to milk from other animal species. The commercial camel products such as dairy, and its conventional usage as ‘Ship of the Desert’ and other multifarious usage in agriculture, transport, security forces, eco-tourism and importance in biomedical research stands apart camel as ‘Multi-utility animal’. This book also gives better understanding to the researchers on information related to promising camel breeds of India, interaction between camel farming and environment, camel reproduction and health issues. Chapters on socio-economic aspects of camel farming and ensuing job opportunities may be helpful in reversing the declining population trend.
... The dromedary camel (Camelus dromedarius) is a valuable species that has evolved and adapted uniquely to hot and arid environments (Raziq et al., 2008). They are low-cost in terms of nutrition but high-yield in terms of milk, meat, wool, and assistance in transport in a variety of situations, especially for the life of a nomadic inhabitant of the Egyptian desert. ...

There is a paucity of published work on genetic evaluation of lactation traits in camels using modern methodologies such as MTDFREML (Maximum Likelihood Restricted by Multiple Trait Derivatives Free of Maximum). The current study aimed to estimate the genetic parameters (direct heritabilities, repeatability and breeding values), and to estimate the phenotypic trend. A 302 lactation records over 10 years for a herd of dromedary camel that were bred at Matrouh Camel Studies and Production Development Center, Animal Production Research Institute, Egypt. Studied traits were lactation traits including total milk yield (TMY, kg), day milk yield (DMY, kg) and length of lactation period (LP). Actual means of TMY, DMY and LP were 1464.90 kg, 4.00 and 418.84, respectively. LP was significantly (P ≤ 0.05) affected by the year and season of calving. Additive heritability ( h 2 a ) estimates for TMY, DMY and LP was 0.25, 0.30 and 0.17, respectively. These are promising values for the potential of genetic improvement. Repeatability ( t ) values recorded a medium value for LP (0.19), while the values were high for both TMY (0.36) and DMY (0.43). The range of predicted breeding values (PBVs) of animals for TMY, DMY and LP were 143.07 kg, 1.5 kg and 113.9 days, respectively. Regression coefficients for she-camels showed a negative annual phenotypic trend (PT) of about − 3.58 kg and − 0.012 kg per year for TMY and DMY, respectively. A genetic improvement program should be followed that allows exploiting the higher estimates of genetic parameters by relying on animals with positive breeding values.
... However, its availability is hampered by the problem of the distancing rangelands, the lack of basic infrastructure for collecting milk and the low milk potential in the natural environment. In fact, productions in the natural environment, cited in the literature (El-Badawi, 1996;Raziq et al., 2008), are generally less than 10 kg, depending on the breed, feeding, lactation stage and milking frequency. In Tunisia, Moslah (1998) reported an average milk production of 1.62 L per day (between 1.22 and 2.02 L per day) during 7 months of lactation for camels reared on rangelands. ...

During these last years, the commercialization of camel milk was developed in Algeria, especially by the intensification of dromedary husbandry and the introduction of forage and concentrated food. For this purpose, the present work aims to identify the influence of camel feeding on the composition of milk, particularly on the technology of its transformation into cheese. Camel milk was taken from two breeding systems, the extensive and the semi-intensive. The results showed that pH and protein content were significantly higher for milk from the semi-intensive farming were 6.54 ± 0.12 and 33.11± 0.85 g/l, respectively. Higher cheese yield was obtained for cheese samples made from a semi-intensive system 24.85 ± 0.22 %. Sensory analysis indicated significant differences in terms of appearance and elasticity (p < 0.05). These observations suggested that camel feeding seems to be partly responsible for certain characteristics of milk. The obtained results could confirm that livestock intensification of dairy camels could develop the commercialization of camel milk while transforming a part of it into derived products such as cheese.

One hundred and ninety nine ovaries were collected randomly from 102 Dromedary camels slaughtered at El-Bassatein and El-Warraq slaughterhouses of Cairo, Giza. Ovaries were placed in punctured plastic bag immediately after slaughter them into thermos containing saline solution (0.9% NaCl) supplemented with antibiotics at 28-30°С. The experiment was conducted to investigate the influence of supplementation of maturation medium with different types of camel serum namely; fetal dromedary camel serum (FDCS), pre-mating dromedary she-camel serum (PMDSCS), mating dromedary she-camel serum (MDSCS) and post-mating dromedary she-camel serum (POMDSCS), on in-vitro maturation rate evaluating the cumulus cells expansion and stage of nuclear maturation of camel oocytes. The obtained results showed that the maturation medium with PMDSCS resulted in improving the average of matured camel oocytes (57.0%) compared to that occurred when the maturation medium was supplemented with MDSCS (31.4%), PMDSCS (41.1%) or without serum supplementation (43.9%), but was not different that occurred when the maturation medium was supplemented with FDCS (47.3%).

With increasing human population pressure and declining per capita production of food in Africa there is an urgent need to develop previously marginal resources, such as the semi-arid and arid rangelands, and optimise their utilisation through appropriate livestock production systems, of which camel production is certainly the most suitable one. The camel (Camelus dromedarius, one-humped camel, dromedary) is an important livestock species uniquely adapted to hot and arid environments. It produces milk, meat, wool, hair and hides, serves for riding, as a beast of burden and as draft animal for agriculture and short-distance transport. It is most numerous in the arid lowlands of Eastern Africa, i.e. in Somalia, Sudan, Ethiopia, Kenya and Djibouti. Approximately 11.5 million animals in this region present over 80% of the African and two thirds of the world's population of camels. This book presents detailed information on the camel in Eastern Africa. Distribution, adaption to arid environments, feeding behaviour and nutritional physiology, products, performances, economic importance, productivity, traditional and modern management practices, diseases, health care and post-mortem procedures are treated with special reference to Eastern Africa. Numerous tables, diagrams and line drawings together with many full colour photographs provide unique visual information for all topics. This publication will be of great interest to anyone dealing with pastoral development in Eastern Africa in particular, but also to livestock specialists, veterinarians, animal ecologists and zoologists in general, to students in these disciplines and, last not least, to all who are fascinated by nature's diversity

Study was carried out to identity, document and characterize the camel breeds of Pakistan. Data were collected on pre-tested questionnaire from different -regions of the country and statistically analyzed. The breeds documented trom various provinces of Pakistan are Larri, Kharai, Sakrai and Dhatti from Sindh; Kachhi, Brahvi, Makrani, Lassi. Rodbari, Pishin and Kharani from Balochistan; Marecha, Bagri, Brela and Campbelpuri from Punjab; Kala-Chitta, Ghulmani, Gaddi, khader and Maya from NWFP and Bacterian (double-humped) from Northern Areas of Pakistan. Habitat and ecology of each breed is described. The data were collected on breed characteristics like morphological somatometeric, growth, production, reproduction traits, draughtability and utility of the documented breeds. The morphological data included the measurement of various body parts, like face, head, ears, neck, hump and somatometeric measurements included girth, height, length and measurement of fore and hind legs. Values of pooled data (of all the breeds) on birth weight, weaning weight and adult weight averaged 46.69, 94.13 and 668.73 kg, respectively. The effects of the breed and sex were significant. Overall means of age at first riding and first loading were 1192.19 and 1435.69 days, respectively. The milk yield and lactation length averaged 1894.93 liters and 445.58 days, respectively. Average age at first breeding in male and female was 4.23 and 3.57 years, respectively. The variations in the trait due to sex and breed were significant. Overall means of dry period and calving interval were 289.83 and 764.87 days, respectively Mean value of riding speed and load carrying capability were 7.69 , km/hr and 406.18 kg respectively. The camel is playing an important role in the agrarian economy of Pakistan. It's role in performing various on and off farm operations (load carrying on back, pulling cart load, drawing water from the wells, drawing Persian well and oil extraction mills etc.) have also been assessed.
