In order to find out whether exposure to environmental pollutants (EP) present in sewage sludge can change the behaviour of sheep, we compared the behaviour of two groups of 5-month old lambs (Ovis aries) with respect to their emotional reactivity and exploratory behaviour. One group (treated, T) comprised the offspring of ewes who had been kept throughout their lives on pastures with slightly elevated, environmental levels of pollutants, as a result of the application of sewage sludge at rates used in normal practice. The other group (control, C) were the offspring of ewes whose pastures had been treated with inorganic fertiliser. During a 1-min period in the weigh crate, T lambs were less reactive than C lambs, but vocalised more. Exploratory behaviour showed a clear sex difference, with female C lambs exploring more than male C lambs. However, this difference was not found in the T lambs, where both males and females showed high levels of exploration. This points to a demasculinising effect of exposure to higher pollutant concentrations with respect to exploratory behaviour. These observations demonstrate the need to take account of the effects of combinations of pollutants, even at very low, environmental concentrations, and further highlight the usefulness of ethotoxicology for the study of biological effects of environmental pollutants.
