Age of puberty: the age of puberty varies for all breeds of cattle but is generally around the 14 month mark. It is important to ensure that a cow has reached puberty before copulation as if to young it may not be able to carry the calf or nurture the calf in the womb.
Length of estrus: The estrous cycle of the cow is generally about 21 days long, but it can range from 17 to 24 days in duration. Each cycle consists of a long luteal phase (days 1-17) where the cycle is under the influence of progesterone and a shorter follicular phase (days 18-21) where the cycle is under the influence of estrogen. The cycle begins with standing heat, or estrus. This time of peak estrogen secretion can last from 6 to 24 hours, with ovulation occurring 24 to 32 hours after the beginning of estrus.
Gestation period: the gestation period for cattle is around 283 days/9 months
