Abstract:
This study was conducted in Khartoum State between January-2010 and June-
2013 to assess the productive and reproductive traits of camels as milk
production animals. Thestudy covered camel milk properties and nutritive
valuetomake available data base for future planning for research in camel
milking efficiency.The methodology followed was included questionnairesin
eleven camel farms. Nine farms in Khartoum North and two farms in
Omdorman. The questionnaire provided information about ( farms, herd
owners, herds, herd men, milking, nutrition, watering, housing and marketing) .
Two farms of similar system of management and had late stage pregnant she
camels of different parity orders were chosed to the experimental work. The first
farm (Major Dr. Alaas) is located at Alkadaro, the second farm (Major. Mahjoob)
located at Alizba.Seventeen she-camels were chosen from 131 lactating she
camels, 132 dry she camels, 131 young females, 72 young males, 8 heifers, 7 adult
males and 11 breeder males.One hundred and eighty one milk samples were
collected from seventeen individual camel (Camelusdromedarius), representing
lactation period (after 5 days of parturition).Using StatSoft, Inc. (2011)
STATISTICA (data analysis software system) version 10 to analyse the
data.Percentage for description of the questionnaire. Taking the farm and the
period from day of start of the experiment to day of calving as covariates, the data
were subjected to analysis of covariance to test the significance of effect of camel’s
type on she- camel milk production traits as well as the lactation curve. Matrix of
coefficients of correlations of lactation performance traits and lactation curve
components ofBushari,Arabi and Anafi. Matrix of coefficients of correlations of
lactation performance and milk composition traits of Bushari, Arabi and Anafibreeds.The survey showed that 81.8% of camel farms were located in Khartoum North
and only 18.2% located in Omdurman, 54.5% of farms had milk production as the
only purpose of investment .The herding types of camel only and camel with cattle
were 36.4%, while herding camel and others represented (27.2%).
Among the camel owners, all of them were more than 40 years old, professionals
were 63.6%, investors were 27.3% and amateur were 9.1%. Non -educated camel
owner constituted 36.3%, university and post graduate were 27.3% each and the
rest were secondary school graduates (9.1%). The majority of the herd men (54,
5%) were educated, while 45.5 were illiterate.
Seven camel breed eco-types were kept in Khartoum State, these were: (
ArabiBushari , Rashaidi,Anafi, Kabashi, KinaniandShukri).That herd size ranged
from 12 up to 216 camels with mean (44), the most frequent herd size was (11-20)
(36.4%).
All surveyed farms supplemented their camels with concentrates. About (73%) of
the farms used green fodder like Abu70 and berseem.
National water net was the most frequent water source (54.5%), followed by wells
(36.4%) and canal (9.1%),(54.5%) of farms did not add additives to the water and
(36.4%) added bicarbonates and common salt.
100% of milking let down stimulation was done with the presences of the
offspring and each she-camel was milked by one milker. Milking all the udder
represented (45.5%), high frequency was (81.8%) for she camels milked twice.
The study revealed high frequency for lactation period was12 months at (54.5%).
The high frequency average daily milk yield/she-camel was recorded (4 kg/day) at(54.5%).Camel milk had been processed to Gariss at (63.6%) of the farms while only one
farm (9.1%) processed ice cream from camel.
Milk marketing in the farm was the most frequent (54.5%). On the other hand
selling milk with 6.5 Sudanese pound / Kg camel milk was the most frequent price
at (45.4%).
The total revenue form milk marketing ranged from 0.972up to 30.912 thousand
SudanesePound. The study found 6 farms out of 9 were selling the camel milk in
the farm gate.
The studied milkproduction traits of the three types of Sudanese dromedary shecamels.
Bushari, Arabi and Anafi she-camels showed that they were similar for
offspring birth weight as percent of dam weight(7.2 ± 1.20%), total milk yield
(1932 ± 955 kg) and lactation period (53.3 ± 14.2 weeks). For the milk yield
persistencyindex (66. 8 ± 14.4%), Bushari she camels excelled their Arabi and
Anafi. Regardinglactation curve components, Bushari, Arabi and Anafi types of
camels had similar initial yield scale (45.4 ± 20.8 kg/week),rate of increase to the
peak yield (0.304 ± 0.238 kg/week), week of peak yield (7.6 ± 2.92 week),
predicted peak yield (63.5± 24.3 kg/week) and persistency of peak yield (4.6 ±
1.17 weeks). Anafi she-camel had lower rate of decrease from thepeak yield (0.021
kg/week) than Bushari and Arabi camels (0.037 and 0.052 kg/week, respectively)
those were similar.The study estimated the average calving weight 490+ 15.6 kg
and thecalf weight (35.2+ 2.42) kg. The total milk yield correlated positively with
all lactation curve component but correlated negatively with constant c and totalbody changesThe milk composition of the studied Bushari, Arabi and Anafi she-camels showed
that there was no significant differences (p>0.05) between the three she camels in
moisture, total solids, ash, lactose, Ca, Mg, Na, K and energy value.
The mean for total moisture was (89+ 0.27%), the mean for total crude protein
was (2.5+ 0.08%), theBushari breed was significantly higher than Arabi and Anafi
in crude protein (2.73%).
The mean for total fat in this study was (3+ 0.2%). Arabi breed is significantly
lower in fat (2.37%) than Bushari and Anafi breed.
The total milk yield correlated positively with all milk composition components
but correlated negatively with moisture, lactose and total body changes, while the
lactation period correlated negatively with all the milk composition traits.
There was no significant effect of herding type, camel breeds, owner relationship
with animals,and herd men education on herd composition percentages in thesurveyed farms
