Days 1–206: early pregnancy
Fertilised eggs implant in the uterus and the embryos begin to develop. Losses are most common now, so keep the asian elephant on a steady diet and avoid stress, transport and abrupt changes in housing.

Asian elephant gestation stages, month by month
Days 207–412: mid pregnancy
Growth is steady but the demand on the mother is still modest. This is the practical window for a pregnancy check, routine health care and any change of pen, paddock or enclosure.
Days 413–566: late pregnancy
Most fetal growth happens now. Energy and protein needs rise sharply, the abdomen enlarges visibly and the mother should be gaining condition rather than losing it.
Days 567–640: preparing for calving
Figures come from zoo and field studies; wild animals should never be handled, and pregnancy is normally assessed by observation or by a wildlife veterinarian. Watch for nesting behaviour, udder or mammary development, restlessness and loss of appetite in the final days before calving.
Signs a asian elephant is pregnant
- No return to heat at the expected interval after mating
- Gradual weight gain and a firmer, rounder abdomen from mid pregnancy
- Appetite increases, often noticeably in the second half of gestation
- A vet can confirm pregnancy by ultrasound or palpation once the asian elephant is far enough along
Signs of approaching calving
- Mammary development and nesting behaviour in the final weeks
- Restlessness, reduced appetite and isolation from others in the last day or two before calving
- Contact your vet if labour stalls, if the animal strains without progress, or if there is abnormal discharge before calving begins.
