Well...
The regular gestation period for a regular horse is 11 months (compared to humans 9 months)
I don't know if it is different because it is a mini, but i don't believe it's different...
The gestation period of a miniature cow is ~284 days.
All horses no matter what breed have a gestation period of 330 to 350 days or roughly 11 months.
The gestation period of a mini cow is around 285 days, which is the same length for a full-sized cow.
The gestation for a cow that's been AI'd would have the same gestation period as a cow that has been naturally bred: around 285 days, plus or minus. Artificial Insemination does NOT affect the length of gestation of a cow, it only affects what her offspring is going to be.
No. Time of weaning does not affect the length of gestation in a cow.
Zebu cows usually have quite a long gestation period, which can stretch from 290 to 300 days in length.
The gestation period of a Chauri cow (which is a cross between a yak and a domestic bovine of Bos primigenius indicusbreeding) is around 9 to 10 months in length, which translates to around 290 to 315 days in length.
The inclusion of the Angus bull is irrelevant to this question since the bull has no control nor part in the length of a cow's gestation period. Expect a Hereford-cross cow to have an average gestation period of around 285 days long, plus or minus a few days.
Since Chianina's are the type of breed that is naturally later maturing than other breeds, and consequently has a lower fertility rate, the gestation for Chianinas is usually between 288 and 294 days in length.
Since Speckle Park cattle are generally early-maturing, the gestation period would typically be around 275 to 285 days in length.
Limousin are selected to have long gestation periods, which is around 290 to 300 days (or more) in length.
The gestation period of a Gelbvieh cow averages around 260 to 280 days long.
For a tiger, the gestation period averages around 100 days. For a cow, the gestation period averages around 285 days.
No Miniature isa horse BREED its probably the smalllest horse breed gestation is when a mare (girl horse) is pregent and careieing a baby foal
