What age can a heifer get pregnant?

How do you know if a cow has miscarried?

Clinical signs of infection included muscle tremors, hypersalivation, reduced consumption of feed, weight loss, excessive shedding of hair, elevated temperature, reduced packed cell volumes and total red blood cell counts, and abortion. One cow aborted on day 41 after inoculation, and another aborted on day 69.

Why is palpation important in breeding cattle operations?

A technique called palpation* can be used to help the producer determine which cows are not bred. Pregnancy diagnosis is an important tool to measure the success of reproductive management of a cattle herd. Rectal palpation is probably the most commonly used method for pregnancy diagnosis.

Is there a urine pregnancy test for cows?

Unfortunately cows do not make bovine chorionic gonadotropin (or any such molecule that is readily detectable in the urine) so a simple test that is similar to the human test is not available. There are, however, a series of candidate molecules associated with pregnancy in cattle (Figure 2).

How much does it cost to preg check a cow?

In the US, an average of 10 to 25% of the cows in a herd are open depending on location and herd size. The vets I have talked with charge between $1.50 to $3.00 per head to preg check cows. If you find one open cow in a herd of 20 – 100 cows you have easily paid for the vet's trip.

What is the approximate length of cattle gestation?

Gestation length does vary by breed and by sex of the calf. Gestation length ranges from 279 to 287 days. For most breeds, 283 days would be common. Cows carrying bull calves tend to have a slightly longer gestation compared to cows carrying heifer calves.

The cervix is located on the floor of the pelvic cavity near the anterior end of the pelvic bone. As you insert the breeding gun into the vagina, keep your gloved hand even with the gun tip. To relax rectal constriction rings, insert two fingers through the center of the ring and massage back and forth.
