135 Abstract: Pharmacokinetics of oxytetracycline were investigated in 20 sheep following intravenous injection of 40, 80 and 160 mg/kg doses. An increase in concentration of oxytetracycline was found with increasing dose at all the sampling times in each animal. The peak plasma concentration of oxytetracycline attained after intravenous administration of 40, 80 and 160 mg/kg of the drug was 18...

Eight male cattle were given a combined dose containing 20 mg/kg oxytetracycline and 0.5 mg/kg diclofenac intramuscularly. Blood samples were drawn at different times until 168 h after administration. Two experimental animals were slaughtered by humane means at weekly intervals up to 28 days after administration. Samples of muscle, injection zone tissue, liver, kidney and fat were obtained. Oxy...

OBJECTIVE To examine the effectiveness of mass medication with long acting antibiotics at feedlot entry on lot-fed Australian domestic cattle during a period of high risk for bovine respiratory disease (BRD). DESIGN Systematic allocation at feedlot entry of tilmicosin, long acting oxytetracycline or no antibiotic treatment, to cattle lot fed for the Australian domestic market. Comparisons of ...

The radiolytic decomposition of oxytetracycline and effects of inorganic ions were studied. The removal efficiency of oxytetracycline , 30 mg/L, was 99% at the irradiation dose of 0.7 kGy. Chloride , sulfate , nitrite , nitrate and phosphate had effects on oxytetracycline degradation. Especially , nitrite and nitrate showed the significant inhibition effect on the radiolytic degradation of oxyt...

OBJECTIVES The Japanese Veterinary Antimicrobial Resistance Monitoring (JVARM) Program was established in 1999 to examine the susceptibility of bacteria from food-producing animals to antimicrobial agents. This study tested the susceptibility of Salmonella isolates collected during 2001-2002 to 20 antimicrobials. MATERIALS AND METHODS MICs of antimicrobial agents were determined using the NCC...

The effect of 2 different oxytetracycline treatments in acute E. phagocytophila infected lambs was investigated. Twenty 5-month-old lambs of the Dala and Rygja breeds were used. Ten lambs were inoculated intravenously with a stabilate of an ovine E. phagocytophila strain. On the third day of fever, 4 lambs were given long-acting oxytetracycline (Terramycin prolongatum vet, Pfizer) (20 mg/kg) in...

The tissue distribution of a long-acting oxytetracycline formulation after intramuscular administration to calves at a dose rate of 20 mg/kg was studied. Oxytetracycline concentrations were determined in lung, bone marrow, mammary gland, uterus, uterine horn, ovary, liver, synovial fluid, joint tissue, kidney, spleen, brain, muscle, fat, urine, bile, saliva, ruminal content and serum. Observed ...
