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 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
IV
use veterinary drugs should be performed to prevent drug residues in
animal products.
