Effect of flavomycin on the performance and blood constituents of friesian and buffalo calves

Flavomycin was given to male buffalo and Friesian calves [20 mg/animal/day] during the fattening period to show its effect on the performance and blood constituents. The obtained data revealed slight increase in the total gain with shortening of the fattening period in the treated animals. Hemoglobin, SGOT, SGPT, total lipids and cholesterol values showed nonsignificant changes. Significant elevation in the total protein, alpha and delta globulins as well as in T3 were recorded

Performing the swab test on premises [stop] for detecting antibiotic residues in calves

Wide use of antibiotics in veterinary practice evoked the development of rapid techniques for detection of their residues in tissues of food animals. A preliminary experiment for detection of antibiotic residues in spiked samples was done beside a trial to investigate the distribution of antibiotic in different tissues [muscle, heart, kidney, liver and serum] of animals after intravenous injection of antibiotic [6 sheep less than one-year old were used]. Applying the Swab Test On Premises [STOP] and the Life Animals Swab Test [LAST] on kidney and urine of 50 calves slaughtered at Cairo abattoir revealed the presence of antibiotic residues in 10% of examined calves
