Cows are at their most fertile between 60 and 80 days after calving. Cows remaining "open" (not with calf) after this period become increasingly difficult to breed, which may be due to poor health. Failure to expel the afterbirth from a previous pregnancy, luteal cysts, or metritis, an infection of the uterus, are common causes of infertility

Once bred, a heifer is pregnant for nine months and, after giving birth, is then considered a cow. During pregnancy, the udder begins to develop further. After calving, a cow will nurse its calf briefly and then typically be milked two to three times daily. Cows produce about 80 pounds of milk per day, though some can produce well over 100 pounds.
[1] [2] Russia topped the overall medal count at 7 Summer Olympics and 8 Winter Olympics, while the United States placed first at 19 Summer Olympics and 1 Winter Olympics. Medal totals of the Soviet Union/Unified Team/Russia/OAR/ROC and the United States since 1956, when the Soviet Union started to compete, are presented below.
Research shows that milk production may be negatively impacted if cows do not acquire enough protein during their dry phase. [13] If farms are unable to provide separate diets for far-off and close-up cows, producers may choose to manage their diets with a shorter dry period and a negative DCAD (dietary cation-anion difference) ration diet.
