Water buffalo Gestation Period: How Long Is a Water buffalo Pregnant?

How long is a water buffalo pregnant?

A water buffalo carries her calf for an average of 310 days, or about 10 months. Counting from the breeding date, calving is normal anywhere from day 300 to day 320.

Water buffalo gestation stages, month by month

Signs a water buffalo is pregnant

• No return to heat at the expected interval, though silent heat makes this unreliable on its own
• Rectal palpation or ultrasound confirms pregnancy from about day 45
• Right side of the abdomen fills out from the middle of pregnancy
• Udder development and swelling of the vulva in the final month

Signs of approaching calving

• Pelvic ligaments slacken and the tail head drops in the final days
• She separates from the herd, becomes restless and goes off feed shortly before calving
• Contact your vet if labour stalls, if the animal strains without progress, or if there is abnormal discharge before calving begins.

What affects water buffalo gestation length

• River-type buffaloes such as Murrah, Nili-Ravi and Mediterranean calve at about 305 to 315 days, while swamp buffaloes carry noticeably longer at around 320 to 340 days — a difference of up to a month between types.
• Buffalo gestation runs roughly three to four weeks longer than cattle gestation, so cow due-date rules give the wrong answer for a buffalo.
• Buffalo show much weaker signs of heat than cattle, with a high rate of silent oestrus, so a missed service date is the most common reason a due date is wrong.
• They are seasonal in their breeding tendency, conceiving more readily in cooler, shorter days, which concentrates calving into part of the year in many herds.
• Buffaloes have very few sweat glands and depend on wallowing or sprinklers; heat stress in late pregnancy reduces calf birth weight and raises the risk of losses.

Find the row closest to the date the water buffalo was served; because normal gestation spans 300 to 320 days, plan for a window of a few days either side.
