Description
Rooting is a strongly motivated, species-specific behaviour of pigs. Most housing systems do not provide appropriate materials that enable the full expression of this behaviour, and it remains unclear whether straw is an appropriate rooting material. We therefore investigated the suitability of small (minimal) and large (deep) amounts of straw as well as large amounts of compost to satisfy rooting motivation in pigs. Fifty-seven growing-finishing pigs were housed in three pens, each providing permanent access to one of the three treatment substrates. Eight pigs per group were tested individually in a conditioned place preference test (CPPT) and another eight pigs in a classical preference test (PT). In the tests, pigs could show their preference to consume freely available food ("feed") or food hidden in sawdust ("root"). In the CPPT, food was only present during training but not during testing. Pigs were exposed to the test situation twice, with approximately 72 kg and 115 kg body weight. In both tests, the following variables were measured and used as outcome variables in linear mixed effect models: first decision to choose one of the two stimuli ("feed" or "root"), duration of…
