Buffalo Heat (Estrus) Cycle Calculator
Predict the next heat dates and best AI/service timing for a buffalo from the last observed heat (cycle ~21 days).
Optimal service/AI timing: inseminate towards the end of heat; buffalo show 'silent heat' often, so watch closely (heat is best seen at night/early morning). Buffalo cycle every ~21 days but show weaker, often nocturnal heat signs than cattle.
Indicative planning figures based on published research averages. Local soil tests, varieties and weather change actual requirements — confirm with your agronomist or extension officer.
Breeders use the free Buffalo Heat Cycle Calculator to predict the next heats and time insemination correctly — the single biggest driver of conception rate.
About Buffalo Heat (Estrus) Cycle Calculator
Timing breeding to the heat (estrus) cycle is what makes the difference between a pregnant animal and a wasted service. Buffalo cycle every ~21 days but show weaker, often nocturnal heat signs than cattle. From the last observed heat, this tool projects the next three expected heat dates and reminds you of the optimal service window (inseminate towards the end of heat; buffalo show 'silent heat' often, so watch closely (heat is best seen at night/early morning).) plus when to do a pregnancy check if she isn't seen in heat again. Good heat detection and timing lift conception rates and shorten the calving interval.

Frequently asked questions
How long is the heat cycle of a buffalo?+
About 21 days. Buffalo cycle every ~21 days but show weaker, often nocturnal heat signs than cattle.
When is the best time to inseminate a buffalo?+
Best timing: inseminate towards the end of heat; buffalo show 'silent heat' often, so watch closely (heat is best seen at night/early morning).
What if the animal returns to heat after service?+
A return to heat at the next cycle usually means she didn't conceive — re-inseminate at that heat. If she doesn't return, pregnancy-check from the date shown to confirm.
Is this tool free and private?+
Yes — free, no sign-up, and all calculation runs in your browser, so it works offline at the farm and your data never leaves the device.
