Dairy farmers usually begin breeding or artificially inseminating heifers around 13 months of age. [11] A cow's gestation period is about nine months. [12] Newborn calves are separated from their mothers quickly, usually within three days, as the mother/calf bond intensifies over time and delayed separation can cause extreme stress on both cow ...
Dairy farmers are extremely familiar with the pattern of milk production and carefully time the cow's next breeding to maximize milk production. The pattern of lactation and pregnancy is known as the lactation cycle. For a period of 20 days post parturition the cow is called a fresh cow.
For mother cows to continue producing milk, they give birth to one calf per year. If the calf is male, it is generally slaughtered at a young age to produce veal. [106] Cows produce milk until three weeks before birth. [103] Over the last fifty years, dairy farming has become more intensive to increase the yield of milk produced by each cow.

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 ...
Female orcas start breeding at around 6-10 years old, males at 10-13 years. Breeding occurs all year round although it is most common in summer. The gestation period of an orca is about 17 months ...
This is an immunologically mediated adverse reaction, rarely fatal, to one or more cow's milk proteins. [119] Milk allergy affects between 2% and 3% of babies and young children. [120] To reduce risk, recommendations are that babies should be exclusively breastfed for at least four months, preferably six months, before introducing cow's milk. [121]

A fresh cow is a dairy term for a cow (or a first-calf heifer in few regions) who has recently given birth, or "freshened." The adjective applying to cattle in general is usually ...
