@ Yassa, the great debate continues.... I certainly do not see it the same way. Here is a list of my opinions about the advantages of hand reared tigers that I am certain you will probably not agree with... but here goes.
1. Mother tigers generally do an excellent job of rearing cubs but mortality is greater than with hand reared tigers. I have had the chance to be with over 125 cubs at or near birth and have had two deaths (before one year of age). It seems that most zoological institution that have strictly mother reared animals have close to thirty percent dying at an early age.
2. Cubs that are hand reared are better adjusted as they are more confident in varied situations. They area less stressed and fearful in situations than non-hand reared animals would be. In all of the cases of tigers I have been with we have never had a case of a female tiger rejecting or killing cubs.
3. Cubs and mothers' make a great exhibit. Typically after a vaccination period cubs would be back on display with adult tigers in groups that may also include their mother. This is an excellent and popular way to display them.
4. It is certainly costlier to hand rear tigers which is a large commitment for most zoos. This is well off-set in terms of increased visitation, increased staff motivation, increased revenue opportunities, and better quality to cubs lives.
5. Long term benefits to tigers are substantial. These include lower stress by external factors, and ability to display tigers in larger groups and keep aggression to a lower level.
6. Much greater ability to generate in-situ funds. Dreamworld and Australia Zoo are the largest zoological donors to conservation. This is only possible due to programs with the animals and public donations that are encouraged by seeing something different than a static exhibit with tigers.
7. Hand reared animals can be more easily conditioned to allow close inspections, routine weight being taken, blood samples to be taken, and general treatments.
8. Breeding of hand reared animals is also easier and safer as they can be more closely monitored and over aggression prevented.
It is always interesting to hear both sides of the argument. I have worked around and with cats that are hand reared and handled and cats that are not. My opinion is that while much harder to manage a quality program like Dreamworld or Australia Zoo has benefits for the individual animals, conservation, and the public that comes to the facilities.
