I hope you are doing great... I'm just curious what different folks out there have experienced both in terms of frequency of estrous cycle and length for gestation once pregnant. Of course I have read the limited literature out there on these issues for Dexters but again, just curious what your collective experiences have been...
1. What have you seen for the frequency of estrous cycles? (Is it really 21 days? More? Less?)
2. What lengths of gestation periods have you had?
It would be interesting for us to increase the overall pool of knowledge in these areas with our collective experiences... thanks in advance for your thoughts on these two areas...
Quote of the Week:
“Farming looks mighty easy when your plow is a pencil and you're a thousand miles from the corn field.”
Almost every one of my Dexters sticks to the 21 day cycle.
With a bull in with the cows 24/7, I can't be too sure about the gestation period. Beth is my herd cow. Once she had her first calf here, she then had calves at 335, 325, 338, 337 and 337 days after the previous one. That includes the time to re-breed and the gestation.
Rufles gave me a calf 9 months to the day after a previous calf. She followed that with a 1 year interval, then a 10 month interval.
I'd say that my Dexters are generally a little quicker than the posted reproductive cycle.
Hi Smokeymtn, 21 days is most usual, but you'd better be watching on day 19 and day 22 and we always watch our cows all the time anyway.. ;D Gestation length..here's a few from recent years: Day 274 bull calf (same cow, same sire, day 274 bull last year also), Day 282 bull, day 279 bull, day 276 heifer, day 281 bull, day 284 bull, day 275 heifer, day 275 heifer, day 279 bull, day 283 heifer, day 279 heifer, day 280 heifer. ..marion
I'm new to Dexters, but not cattle. 18-24 days would be a normal range for heat cycles with 21 being most typical. Varying cycles could be a sign of a problem, as usually they'll run within a day of what ever is normal for that specific cow. I don't know the gestation length for Dexters. It varies between breeds a little. Of the ones I know 276-290 days, a two week difference between the Ayrshire and the Brown Swiss. Most breeds are around 283 days. Hope this is useful.
