There is no "medicine" that is used for dairy cows to increase milk production. Only a particular growth hormone called rBGH or recominant Bovine Growth Hormone.
To increase milk production.
There is no "other" name. Dairy cows are dairy cows, no matter how you look at it, particularly in reference to mature females that are raised for the production of milk.
The hormone that is injected into dairy cows for increased growth and milk production is called recombinant Bovine Somatotrophin Hormone or rBST, purchased as Posilac by American dairy farmers.
Dairy farming is an agricultural term to mean the long term production of milk, generally from dairy cows. The production can either be done onsite or transferred to a dairy factory.
Jerseys are mainly used for milk (dairy) production.
No, it decreases milk yield.
Sahiwal is a breed of Zebu cattle which primarily is used in dairy production.
Dairy cows that are crossbred to zebu-type cattle are the best types that will handle a tropical climate. Even pure B. indicus cattle that are selectively bred for dairy production are the best for handling such climates.
Milk is the most important product that dairy cows have to offer, and it has become sort of a necessity for dairy farmers to being breeding heifers as soon as they are able to. A cow cannot produce milk until after calving or parturition (or giving birth). So at around two years of age, the heifers are bred to give birth and officially become dairy cows that can produce milk. Dairy cows will reach its milk production peak at around 40 to 60 days after giving birth. After that, production will steadily decrease. Eventually the milking will cease when the cow is dried off after about 305 days. The dairy cow can calve again a year after her first birth. For high production cows, though, it is viewed that 13 or 14 month cycles is appropriate because high production cows are more difficult to breed.

fun facts about dairy cows
When a dairy farmer chooses which cows to breed based upon milk production, he is taking advantage of natural selection.
Usually a dairy farmer keeps a herd of cows for milk production, selling the milk to an industrial creamery/milk processing plant.
