There is still a body of opinion opposed to harvest of wildlife on 
sentimental or other grounds, but it is gradually being overcome by the 
obvious needs and the success of the present relatively small scale 
operations. 
Disease and marketing 
An important obstacle to more rapid expansion of wildlife harvesting 
in East and Central Africa is the series of veterinary restrictions based 
on the dangers of disease. Although disease may be controlled in domes¬ 
tic livestock, the same measures often cannot be applied to free-ranging 
wild animals. The presence or absence of livestock diseases is often a 
determining factor in the export industry of these countries. Because 
of the danger of disease transmission, meat from both wild and domestic 
animals often cannot be transported from the areas where it grows to the 
areas where there is a demand for it. 
There are many strong opinions but there is still relatively little 
solid scientific information on the incidence of diseases in wild animals 
and their transmission to and from domestic livestock. Further research 
is required on this subject to facilitate proper exploitation of the wild¬ 
life resource in this area. It is possible that canning might provide the 
best means of overcoming the disease dangers in processing and marketing 
meat from both game and livestock in quarantine areas. Investigation in 
this field is also required. 
Techniques 
Development and improvement of techniques is a problem basic to 
almost any new industry. Although effective methods are now being em¬ 
ployed, further development work is required to adapt techniques of 
management, harvest, and processing of wild animals to the different 
conditions involved. 
SUMMARY AND CONCLUSIONS 
Conditions adverse to optimum production of domestic livestock exist 
over much of the world. Many areas are marginal or submarginal for main¬ 
tenance of domestic livestock, and equally important, for maintenance of
