Animal by-products result mainly from the slaughter of animals for human consumption, the production of products of animal origin (such as dairy products), the disposal of dead animals, and disease-control measures. Regardless of their source, they pose a potential risk to public and animal health and the environment. This risk needs to be adequately controlled, either by safe disposal of such products,...
Tetracycline antibiotics, including tetracycline (TC), chlortetracycline (CTC), oxytetracycline (OTC) and doxycycline (DOX), are commonly used in veterinary medicine because of their broad-spectrum activity, cost effectiveness and certain favourable pharmacokinetic properties. The use of antibiotics in feed for non-medicinal purposes has been prohibited in the European Union. In Poland and other countries...
A high performance liquid chromatography combined with fluorescence detection (HPLC-FLD) method was developed for determination of five ergot alkaloids (EA): ergometrine, ergotamine, ergocornine, ergocrypine and ergocristine in animal feedingstuffs. The method was based on the application of QuEChERS salts for extraction and modified QuEChERS dispersive SPE for the cleanup step. Alkaloids separation...
A liquid chromatography - diode array detector (HPLC-DAD) procedure has been developed for the determination of oxytetracycline (OTC), tetracycline (TC), chlorotetracycline (CTC), doxycyc-line (DC), enrofloxacin (ENR), ciprofloxacin (CIP), sarafloxacin (SAR) and flumequine (FLU) residues in animal drinking water. This method was applied to animal drinking water. Solid-phase extraction (SPE) clean-up...
