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.
Each pregnancy lasts for three months, three weeks, and three days [citation needed]. Sows will have an average of 2.5 litters every year for two or three years, most of which is spent in the crates. Sows will have an average of 2.5 litters every year for two or three years, most of which is spent in the crates.
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

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.
Animal non-reproductive sexual behavior encompasses sexual activities that non-human animals participate in which do not lead to the reproduction of the species. Although procreation continues to be the primary explanation for sexual behavior in animals, recent observations on animal behavior have given alternative reasons for the engagement in sexual activities by animals.
