Scientific literature on pig behavior and its practical application was reviewed and discussed. Areas were identified where behavioral research is likely to produce major benefits in productivity. It was noted that some husbandry practices appear to be out of harmony with the behavior of domestic animals, and that an imaginative research effort is needed to improve confinement rearing of pigs.

In 2 experiments, groups of 3 pigs aged 4-8 weeks were given access to 2 sides of an experimental pen, one with straw bedding and one with a bare concrete floor. When resting or feeding, the 12 groups in experiment 1 showed no consistent preference for the bedded or unbedded side. when active, the pigs were more often on the bedded side, especially at times when fresh straw was provided. The quantity of straw had no effect on these trends In the second experiment, 10 groups tested at an ambient temperature of 18-21°C strongly selected the bedded side for resting, while those tested at 25-27°C usually selected the bare concrete. Feeding and general activity showed no clear relation to floor type. At the cooler temperatures, most groups dunged on the side that was not used for resting and feeding, but this structuring of the living space was not so apparent at the higher temperatures. The results indicate that the animals preference for a bedded or concrete floor depends strongly on temperature. Under warm conditions, straw is likely to benefit pigs becouse of its recreational value but not as a means of imporving comfort in the resting area.
