Abstract:
The objective of this study was to establish antibiotic
withdrawal time in camel and cow products and compare
that to what proposed by drugs companies. Forty two
camels were used in the study. They were divided into 3
groups of 14 animals each. One drug was injected into
each group (Sulphadimidine sodium 33%, Terramycin
(50mg/ml), and Ampicillin sodium for 3 days. Thereafter,
samples of blood were first collected for analysis. Two
animals from each group were slaughtered after 24 hours,
3, 7, 14, 21, 28, and 35 days following antibiotic
administration. Liver, Kidney and muscle were collected
for further analysis. Samples of camel product collected
from slaughterhouse at a period of 4 weeks ( 200 samples
Liver and 200 samples Kidney). The results of the 4
antibiotics which further confirm the observation that
withdrawal period in the camel to be significantly longer
than in cow. The values were 4days for cows and 5 days
for the camel for ampicillin and cloxacillin, 4 days for the
cow and 6 days for the camel for oxytetracycline and
cefruxime. The withdrawal period of ampicillin,
oxytetracyclin, and sulphadimidine in camel milk and
tissues was found to be longer as compared to that of
3
other animals. Residue concentrations of antibiotic that
exceeded MRL were found in dairy camel milk and tissues
of slaughtered camels.
It is recommended that estimation of withdrawal period
should be done for every drug in camel and not
extrapolated of doses from other animals. Effects
including awareness, creation and observance of
withdrawal period should be employed. Effective
surveillance, monitoring and control of the use veterinary
drugs should be performed to prevent drug residues in
animal products.
