Elimination of sulfamethazine residues from swine. 1979

G Samuelson, and D M Whipple, and D H Showalter, and W C Jacobson, and G E Heath

Tissue concentrations of sulfamethazine in swine fed the drug at the rate of 500 g/ton of ration (550 g/1,000 kg) for a 30-day period depleted to 0.1 ppm or less within 4 to 10 days after withdrawal of medicated feed. Depletion from the tissues and plasma of treated pigs showed a linear relationship with time when the concentrations were plotted on a semilogarithmic graph. Six untreated pigs that were placed on bedding in pens formerly occupied by the treated group developed tissue residues at or above 0.1 ppm sulfamethazine; the mean plasma concentration of sulfamethazine reached 2.8 ppm by day 15.

D000273 Adipose Tissue Specialized connective tissue composed of fat cells (ADIPOCYTES). It is the site of stored FATS, usually in the form of TRIGLYCERIDES. In mammals, there are two types of adipose tissue, the WHITE FAT and the BROWN FAT. Their relative distributions vary in different species with most adipose tissue being white.
