disadvantages include the negative effects of physical punishment and<br />
negative reinforcement (acute and chronic); consequences of being<br />
‘dominated’ by the keeper, such as reduced fertility; transient relationships<br />
between elephant and keeper (due to high staff turnover and limited working<br />
hours); and health problems induced by training ‘power behaviours’ (e.g.<br />
head stands; hind-leg stands). Protected contact is said, at least by some, to<br />
encompass most of the pros of traditional training, but with the added<br />
advantages of allowing elephants to choose whether or not to participate in<br />
training sessions (cf. traditional training where 100% compliance is required);<br />
not using physical punishment and improving the behaviour of problem<br />
animals. It has been argued, however, that not all veterinary procedures can<br />
be undertaken and elephants do not gain sufficient physical exercise. No<br />
contact systems are rare, but could potentially provide the most naturalistic<br />
form of care. Such systems negate the use of punishment as no training is<br />
undertaken, however, veterinary procedures cannot be undertaken without<br />
the use of anaesthesia and some say that elephants do not get sufficient levels<br />
of physical exercise or mental stimulation, said to occur during training. These<br />
purported pros and cons of different management regimes need to be<br />
investigated to quantify the effects of each system on elephant health,<br />
behaviour and reproduction. In addition, the response of elephants to their<br />
keepers in these different regimes should be determined, particularly in<br />
traditional systems, to try and determine whether elephants really do respond<br />
to their keepers as another group member (or indeed group leader).<br />
Foot and joint problems: incidence, severity and risk factors<br />
Foot and joint problems appear to be very common in zoo elephants, although<br />
their incidence does not yet appear to have been quantified. Aspects<br />
suggested to be associated with these problems include: hard, unyielding<br />
substrates; long periods of chaining; nutrient deficiency; excessive body<br />
weight; the performance of ‘power behaviours’ (e.g. head stands; hind-leg<br />
stands); stereotypic behaviour and general stress. Factors thought to alleviate<br />
them include regular foot care (which may differ in different management<br />
systems); regular exercise and access to mud wallows and natural substrates.<br />
The influence of these various factors on foot and joint health needs to be<br />
investigated, in addition to quantifying the incidence and severity of these<br />
problems in zoo elephants.<br />
Stereotypic behaviour: incidence, frequency, source behaviours and risk<br />
factors<br />
The stereotypic behaviour of zoo elephants has not received much attention,<br />
but from the data that are available, 40% of elephants studied showed these<br />
behaviours to some degree, albeit at a generally low frequency. Research on<br />
orphaned elephants suggests the behaviour stems from restricted movement<br />
and possibly impaired social interaction. Due to the possible link to welfare,<br />
the incidence and severity of stereotypies needs to be scientifically quantified,<br />
possible causal factors identified and investigated.
