The cows teat is a projection of the mammary gland that is sealed during their dry period. A dry cow refers to a dairy cow that is in a stage of their lactation cycle where milk production ceases prior to calving. This part of their lactation cycle is referred to as the cows dry period and typically last between 40 and 65 days. [1]
A cow goes through three stages of labor during normal delivery of a calf. During stage one, the animal seeks a quiet place away from the rest of the herd. Hormone changes cause soft tissues of the birth canal to relax as the mother's body prepares for birth. The contractions of the uterus are not obvious externally, but the cow may be restless ...
Ear tagged calf and cow in Andorra. Video of calf suckling in Bulgaria. A commercial steer or bull calf is expected to put on about 32 to 36 kg (71 to 79 lb) per month. A nine-month-old steer or bull is therefore expected to weigh about 250 to 270 kg (550 to 600 lb). Heifers will weigh at least 200 kg (440 lb) at eight months of age.

A typical precocial mammal has a gestation period almost four times longer than a typical altricial mammal of the same body size. [24]
The gestation period averages 285 days, but varies depending on the age and nutrition of the mother. The sex of the calf may also affect the carrying time, as male calves are carried for a longer period than females. Location, breed, body weight, and season affect the overall health of the animal and in return may also affect the gestation period.
Cattle originally meant movable personal property, especially livestock of any kind, as opposed to real property (the land, which also included wild or small free-roaming animals such as chickens—they were sold as part of the land).
