Reproductive ecology of the warthog phacochoerus aethiopicus and its significance for management in the eastern selous game reserve tanzania

Animal collection and field observations were used to establish the recruitment pattern of the population field observations were used to establish the recruitment pattern of the population. Female warthogs reached sexual maturity at about 2 yr of age. There was a fairly high reproductive rate, with 87% of sexually mature females producing an average of 2.6 hoglets/yr. Breeding occurred in April and May, farrowing in Sept., Oct. and Nov. This suggested a gestation period of about 5 mo. Females of 4 and 5 yr of age were more productive than younger or older ones. The pre-natal sex ratio was 1:1, but the post-natal sex ratio deviated from unity. Mortality was highest in younger and very old animals. The importance of data on reproductive ecology to efficient game management is stressed.
