ResumoTaste preferences in young pigs have been examined using both long term and short term two choice preference tests. The substances used were examined over a wide range of concentrations; they included sucrose, glucose, sodium saccharin and sodium cyclamate. Relative to water the pigs had a very strong preference for solutions of sucrose and glucose and a strong preference for saccharin. They displayed no preference for solutions of sodium cyclamate. Using operant conditioning methods it was possible to demonstrate that the pigs would learn to perform operant responses in order to obtain sucrose solutions and their motivation to respond on progressive ratio schedules of reinforcement was related to the concentration of sucrose which they obtained.
