Results from our previous research indicate that long-term tether-housed pigs with high and low levels of stereotypies show differences in the density of endogenous opioid receptors in the hippocampus and hypothalamus. It was not clear whether differ

The food consumption (recorded in kg of individual fish species), body length and mass of 11 Atlantic bottlenose dolphins kept first at Windsor Safari Park, UK (1979-1993/1994), and later at Harderwijk Marine Mammal Park, The Netherlands (1993/1994-1

Food consumption, body weight and body length were recorded in four female common dolphins (Delphinus delphis) at Marineland of New Zealand between 1974 and 1996. The study is based on historical data that were recorded for short-term husbandry purpo

The daily food consumption of 26 California sea lions at the Harderwijk Marine Mammal Park was recorded. Average annual food consumption of males increased with age to stabilize at approximately 4,000 kg/year by the age of 10 years. Females showed a

Proceptive and receptive aspects of behaviour were studied during the oestrus cycle of the female pig. These aspects were studied in a T-maze with one or two stimulus compartments that did or did not contain a teaser boar. Receptive behaviour was obs

At a commercial farm we investigated how profitable it is to compose groups of pigs based on individual behavioural characteristics. In two successive backtests each of 206 piglets were individually restrained in a supine position, and classified as

Previous experiments demonstrated consistent individual behavioral differences in pigs. Some showed a more active behavioral response (so-called A/R pigs), others a more passive behavioral response (so-called NA/NR pigs). In the present study we sele
