The research was carried out in the center of the Research and
Improvement of Sheep and Camels in salamiah. The study was
conducted on 9 female camels, within semi-open barns, semiintensive
care system, and the camels were fed on mixtures of
barl
ey, vetch and some concentrated fodder, Fodder mixtures were
determined to suit the nutritional needs of the physiological and
age-related condition of the study. The herd was also applied to the
preventive vaccination system according to the preventive immunity
program.
The aim of this research is to study the effect of sex, age and anatomical location on
the chemical composition and amino acids of Syrian fattened camel meat.
Samples from dorsal rectangular muscle (Longissimus dorsi), and Semimembranous
muscle in
three age groups (1.5 - 2 years, 3 - 4 years and 5 - 6 years) were analyzed
in triplicates from every age group and from each sex.
Percentage of moisture and protein in the flesh of males was higher than the flesh of
females. Moisture and protein decreased, while fat and ash increased according of animal's
age. Moisture, protein and ash were higher in Semimembranous muscle, while fat was low.
The amounts of amino acids were higher in the flesh of males than the flesh of
females, but the amount of methionine was opposite. The amounts of valine, iso-leucine,
methionine, alanine, glutamine, and tyrosine decreased, while The amount of leucine,
threonine, tryptophan, phenylalanine and aspartic increased by animal age. The amounts of
valine, leucine, methionine, alanine, arginine, histidine, glutamine and proline increased
while the quantities of iso-leucine, threonine, tryptophan, phenyl-alanine, aspartic, tyrosine
and glutamine decreased in semimembranous muscle compared with dorsal rectangular
muscle.
Ten growing Shami female dromedaries, 27 weeks old were used to
determine peripheral levels of glucose, IGF-1 and leptin in prepubertal Shami
dromedary heifers. Body weight(BW) was measured and blood samples were
collected weekly from the jugular
vein for 6 months in EDTA-containing tubes.
Serum was separated and stored at −20°C for later analysis. Glucose was
determined using a colorimetric glucose oxidase kit. Serum concentrations of
IGF-1 and leptin were assayed using some modifications of bovine radioimmunoassay
procedures. Animals were grouped according to their birth date,
body weight or average daily gain and variations in the plasma concentrations
of parameters as well as to the effect of studied factors were tested and assessed
by analysis of variance using the general linear model, repeated measurements
procedures of SAS. It is reported for the first time information on peripheral
levels of glucose, IGF-1 and leptin hormones in sexually immature dromedary
heifers and results indicated that BW had a significant effect (p<0.05) on IGF-1
levels. Overall means for glucose, Igf-1 and leptin, were 188 ± 4.11 mg\dl, 222 ±
6.43 ng\ml, and13.27 ± 0.16 ng\ml, respectively and it was found that those
concentrations were greater than values in sexually immature females in the
other domestic animals. Such information might be helpful for specialists to
search for the role of these hormones in the reproductive function and develop
breeding programs to reduce the period of the onset of puberty and increase
the reproductive performance of dromedary camels.
This study was carried out at Camel Research Station, Deer Al-Hajar,
Directorate of Animal Wealth Research, General Commission of Agricultural
Scientific Research to measure the testicular dimensions, TDs (Length, TL;
width, TW; Circumference, TC)
; the relationship between these parameters
and to use them as an indicator to determine the puberty age in Shami camel
males. Twenty five camel raised in the station were equally divided, according
to their age, into five groups: G1, almost one year,G2, G3, G4, and G5 were 2,
3, 4 and 5 years old, respectively.
A microbiological study carried out on a total of ١٣٤ nasal cavity swabs
were aseptically collected from apparently healthy camels, and examined
microbiologically.
The bacterial examination resultes isolation of ١٣ pathogenic and
Potentially path
ogenic bacteria isolates. These bacteria included: Pasteurella
multocida, E. coli, Streptococcus pyogenes, Citrobacter sp., Edwardsiella,
Klebsiella aerogenes, Staphylococcus albus, Enterobacter, Diplococcus
pneumonia, Serratia marcescens, Micrococcus sp., Providencia sp. and
Corynebacterium sp.
