The invention relates to a method for the detection and/or measurement of a phenol comprising: (a) contacting the sample to be tested with a polymer imprinted with the phenol or an analogue thereof; and (b) measuring binding of the phenol to the polymer. The polymer may be prepared by polymerizing a polymerizable monomer, to which a phenol is covalently bound by a hydrolysable linker, and subsequently removing the phenol by hydrolysis. Propofol is a preferred phenol for use in the invention.

Polymers for binding of phenols

A method of providing an indication of pH levels in an animal can alternatively be used to provide an indication of stress in an animal. Since pH and temperature are related to ultimate meat quality, the method of the invention may also be used to provide an indication of ultimate meat quality. In the method, periodic measurements are obtained corresponding to the body temperature of the animal. An algorithm is applied to the measurements obtained. The algorithm cumulatively takes account of variations of body temperature over time. The results of the algorithm are compared to a per-determined threshold. Alternatively, the results of the algorithm may be compared with a standard to provide a quantitative indication of pH, stress or meat tenderness. A system for providing an indication of meat quality/stress levels or pH levels in an animal is also provided.

The invention relates to compositions and methods for promoting production gains in animals, and of enhancing the efficacy of therapeutic agents. The gains are achieved through reduction in stress, including through the use of antistress agents. Compositions comprising therapeutic agents such as anthelmintics, and antistress agents are provided.
