Artificial light and daylight inlets have an impact on milk production and cow behavior. [41] For cows in lactation a light program of 16 hours light and 8 hours of darkness is recommended, [42] while for non-lactating pregnant cows 8 hours of light and 16 hours of darkness seem to be a better fit.

The hormonal endocrine control system drives milk production during pregnancy and the first few days after the birth. When the milk supply is more firmly established, autocrine (or local) control system begins. During this stage, the more that milk is removed from the breasts, the more the breast will produce milk.
It has been bred selectively to produce the highest yields of milk of any cow. The average in the UK is around 22 litres per day. [102] [103] Dairy is a large industry worldwide. In 2023, the 27 European Union countries produced 143 million tons of cow's milk; the United States 104.1 million tons; and India 99.5 million tons. [107]

Cow blowing, [1] Kuhblasen, [2] phooka, or doom dev [3] is a process in which a farmer forcefully blows air into a cow's vulva or anus to supposedly induce her to produce more milk. A tube may be used to provide some sanitary separation between the blower and the cow, although not every culture that practices cow blowing does so.
Once the cow has entered this stage, producers will seal the cows teat while following a veterinarian recommended, dry cow therapy for their herd. This dry period is a critical part of their lactation cycle and is important for the cows health, the newborn calf and future milk production, as it allows the cow time to rest, eat and prepare for ...
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 ...
