Heifers tend to reach puberty by the time they are 8 to 15 months of age. Bulls will reach puberty by the time they are 10 to 20 months of age.
Simmental bull calves will reach puberty when they get to be around 10 months of age, and are commonly used for breeding when they are past 12 months old.
A Limousin heifer is expected to hit puberty at around 8 to 10 months of age, though some fertile lines have had heifers reach puberty earlier.
Bulls can reach puberty by the time they are 8 months of age, but most are put in with the breeding herd by the time they are 12 months of age. Heifers reach puberty by the time they are 10 to 12 months of age, but most heifers are not bred until they are 15 months old. Of course the breed of the bulls and heifers depends on when they reach puberty and/or when they should be used for producing offspring.
Between six to nine months, they will reach puberty and become sexually active.
This depends on the breed and environmental and nutritional factors. Early maturing breeds and/or herds that have highly fertile cattle can have heifers entering puberty at 4 to 8 months, which, if not weaned or separated from bull calves or the older bulls, will result in a "whoopsie heifer". The oldest a heifer be to reach puberty is 12 to 14 months.
Simmental bull calves will reach puberty when they get to be around 10 months of age, and are commonly used for breeding when they are past 12 months old.
Girls reach puberty earlier than boys at the age of 9-12 years. Boys reach puberty at the age of 12-14 years.

She will naturaly come into heat every 21 days, however, if she is not coming in heat an injection of a synthetic prostoglandin is recommended. This will cause regression of the corpus luteum (what aids in heat cycles). You will see a heat cycle within 2 to 5 days post injection. Discuss with your veterinarian what injection is available in your area and what is best suitable for your herd. An example of this type of injection is Estrumate.
puberty is actually a government conspiracy
Zebras reach puberty at about 4 years of age.
Baby cows are calves, can calves are only calves until they are one year old. Up to then they are known as yearlings. Females reach maturity at 3 to 4 years of age and are known as cows, and males reach maturity at the same age and are known as bulls. Cattle are NOT babies when they are 6 years of age!!
Pubertal ranges are different for boys and girls and even country to country. In America, girls on average reach puberty around the age of 11 or 12. Boys reach puberty by 12 or 13. It has been observed that in recent times, the average age of puberty onset has been decreasing.
A Limousin heifer is expected to hit puberty at around 8 to 10 months of age, though some fertile lines have had heifers reach puberty earlier.
Calves shouldn't be cycling. They're often too young to be able to reach puberty, unless she comes from a very fertile herd where the young ones are coming onto puberty early.
During Teenage Years(Puberty)
Sperm and semen production officially starts when they reach puberty, but bull calves can also start semen production even before they are born.
