EEP Annual Report 2007 - 2008
Calculations carried out using animals with unknown parentage (with 53.1% this is a large proportion of the population) show us that we need to
substantially increase the population from 210 animals to 425. Alternatively we could increase the effective population size (the number of animals
breeding in the population).
Steps are being taken to reduce the unknown parentage information within the studbook, but much of this is historical or from institutions which hold
multi-male adults and are unsure of the parentage of offspring.
Aims of captive management:
• Limit breeding from individuals with high inbreeding coefficients or mean kinship value.
• Promote breeding from potential founder individuals, or those of high rank (indicated by low mean kinship values).
• Breed animals of similar mean kinship.
• Actively move individuals within the EEP to promote breeding between individuals from different pedigrees, and to aid the above aims.
• Promote the keeping of multi-male multi-female groups.
