Low analytical recoveries of the glycopeptide antibiotic, avoparcin, have been observed in several types of compound animal feedingstuffs, particularly dairy and beef finishing feeds (Fagan et al., Analyst, 1995, 120, 2265). Individual compound ratio

19‐Nortestosterone (s‐NT) is banned for use as a growth promoter in food animals within the European Union. For regulatory control purposes, urine and bile samples are routinely screened by immunoassay. The aim of the present study was to compare

Anecdotal evidence in man suggests that abuse of anabolic androgenic steroids (AAS) is linked with increased aggression. In order to test the hypothesis that administration of nortestosterone (beta-NT) esters may increase aggression, behavioural effe

Violative chlortetracycline (CTC) residues in excess of the maximum residue limit (MRL) have been identified in 0.9% of all pigs tested at slaughter in Northern Ireland. Three experiments were carried out to investigate the possible reasons. In Exper

Poor recovery of the glycopeptide antibiotic avoparcin from certain animal feedstuffs, e.g., dairy feeds, has been experienced by this laboratory and has been reported elsewhere. It is postulated that this may be due to binding of avoparcin to specif

The Medicines (Animal Feeding Stuffs)(Enforcement) Regulations 1985 require avoparcin in compound feeds to be determined by an official microbiological method. This method is susceptible to interference from ionophore antibiotics and chlortetracyclin
