Survival, especially the youth, is critical for the reproduction of a species. Giant panda (Ailuropoda melanoleuca) cubs are not well developed and are vulnerable at birth, and they have developed many survival strategy to assist with survival until adulthood, including rapid growth of their young. By analysing the changes in the daily milk intake and weight gain during the early stages of cub growth for 11 years (2004–2014) over 42 healthy giant panda cubs, we found that milk intake by the cubs increased rapidly during the first 10 days. After 10 days, the daily milk intake decreased gradually and stabilized beginning at 35 days. In addition, the cubs with lower birth weight exhibited higher daily milk intake, while those with higher birth weight consumed less milk per unit of body weight. This study explored the characteristics of daily milk intake during the early growth stage of giant panda cubs, offering insight into adaptations strategy of newborns in this species and providing valuable information for artificial rearing to improve the survival rate of captive panda cubs.
