There is no difference. Diagnosis of pregnancy in cows versus heifers is just as likely to be difficult or easy in one and the other.
Short bred cows or heifers are females that are in early gestation or pregnancy, mostly in their first trimester.
pregnancy diagnosis
No. When bred, cows or heifers will begin to develop an udder during the last stages of pregnancy.
Heifers.
Yes. Quite often cows that already had experience calving will have a much easier time popping out a calf than ones (like heifers) that haven't.
Usually it is better to butcher a beef steer but heifers are okay.
If you are referring to the hymen of the vagina, no, cows nor heifers have such a membrane on their vulva.
Breeding season for cows and heifers should be from 45 to 90 days long. Sixty days is considered optimum.
Not necessarily. It means cattle in a collective term, not cows as in only cows with calves, or dry cows or pregnant cows or bulls or steers or heifers or whatever. When a cattleman says that he has 50 head of cattle, he means cows, bulls, steers, heifers and calves, not just the cows themselves.
People don't usually neuter cows. people keep cows for milk and to produce milk cows need to have calves so there is not point in neutering them. The male equivalent of a cow is a bull. Males that are neutered are called a steers.
The function of a bull is to operate as half of your entire cow herd. In other words, his job is to breed your cows and sire as many offspring as he can in his lifetime with the many cows and heifers he is offered to service and as many cows and heifers allow his services.
