Residues of Synthetic Antibacterial Feed Additives in Tissues and Eggs of Chickens

Pharmacokinetics of veterinary drugs in laying hens and residues in eggs: a review of the literature

“…, 1963; Smith, 1964; Pan & Fouts, 1978; Botsoglou & Fletouris, 2001). The single study available on the deposition of dinitolmide in eggs did not continue sampling eggs long enough to establish the full time course of drug elimination, but drug residues were still present 2 weeks after the medication was withdrawn (Nose et al. , 1982) (Table 11).…”

“…, 1982) (Table 11). Concentrations of dinitolmide residues were approximately 10 times higher in the egg yolk than the albumen (Nose et al. , 1982).…”

“…When administered to laying hens, decoquinate is deposited in egg yolk (Kouba et al. , 1972; Nose et al. , 1982) and persists for very long periods [over 4 weeks in some studies (Seman et al.…”

“…, 1967). Amprolium administered to laying hens is deposited primarily in the egg yolk, and residues can be detected in eggs for 2 weeks or more after cessation of treatment, depending on the dose and assay sensitivity (Nose et al. , 1982; Kan et al.…”

“…, 1966). Based on the limited data available, it appears that little or no ethopabate administered orally to laying hens is deposited in eggs (Nose et al. , 1982) (Table 11).…”
