How many years can a beef cow produce calves?
Reproductive performance consistently began to decline at 10 years of age and dropped even more steeply at 12 years of age. Some research suggests that maximum longevity for optimum economic returns is within the range of 8 to 11 years for commercial cow-calf operations.
Can you breed a cow back to her son?
Mating of beef cattle that are close relatives (brother-sister, sire-daughter, son-dam) produces high levels of inbreeding. Inbreeding generally is detrimental to long-term reproductive performance and growth. Highly inbred cattle are also more susceptible to environmental stress and health problems.

After puberty, a heifer continues to have regular estrous cycles every 21 days (the normal range is every 18 to 24 days). The estrous cycle in cattle is complex and regulated by several hormones and organs (see Figure 1). Figure 1 —Phases of the bovine estrous cycle.
How soon will a cow breed back after calving?
60 to 90 days
After calving, it takes 60 to 90 days for cows to resume cycles. This period is called postpartum anestrous. In first calf heifers, postpartum anestrous lasts longer than mature cows. It normally takes 90 to 120 days for first calf heifers to resume cycles.
How many years is a cow pregnant?
A cow’s pregnancy lasts about 9 months and 10 days. When a calf is born, it usually weighs around 45 pounds and can stand and walk within an hour. Our calves are moved into the nursery shortly after they are born, so our farmers can look after and care for them closely.

Should you keep a heifers first calf?
Heifer development is one of the most substantial expenses for beef cattle operations. Time quickly gets away when you’re a cow-calf operator, but it’s essential to keep the first calf heifers on track. Heifers conceiving early in their first breeding season will have increased lifetime production and efficiency.
