The age of the first successful breeding, sex ratio at birth, seasonality of reproduction and mortality rate are presented. The females or males of red goral born in captivity can give their first birth at the age of 2 or 3 separately. The births mainly occurred from May to July and peaked in June. Ratio of females to males at birth was 2.36∶1. The mortality rate for infants and adults were 23.1% and 11.8%, respectively while there was no sub-adult death recorded during the 20 years period. There was a definite relation between mortality rate and seasons and mainly in July.展开更多
