This is Autumn, our 8 year old Jersey cow.
She was artificially inseminated in August 2018, and her “official” due date was yesterday, June 6.
Here is a gestation chart from Select Sires. It is based on a 283 day average gestation for cattle.
And if you’re counting, yes, that’s 9 1/2 months. Much the same as a human.
We have been watching her, and tonight we moved her inside the barn.
Her udder is full and getting tight, which is a sign of impending parturition (the scientific term for giving birth).
Her vulva is also swollen, and her pelvic muscles are relaxing, preparing her body for delivering a calf.
She is also beginning to have some mucous discharge which is a sign of a softening cervix.
I will update tomorrow!
