Artificial Selection
Eat, stay healthy, & succesfull breed to produce more cows to sell.
Cows are bred to produce calves which are often sent to be "made into" beef. So in a nutshell, the answer to your question may very well be "yes."
Yes. You need to put a bull inside a dairy farm with cows in it so that you'll get the chance to produce a calf for your friends to adopt.
Dairy cows, those cows that are selected for and bred to produce milk.
Selective breeding, the farmer will select what bulls to breed to what cows in order to increase milk production.
Breed with bulls to produce calves, graze grass and hay offered to them by humans, sleep, etc.
The past of the word breed is bred. You can say something like "The bull has been bred in the past" or "We bred the bull to all of the cows to produce superior stock".
Those cows that are consistent in milk production, calving ease, fertility, mothering ability, etc. and are able to breed on time and produce a calf every year.
Any cow can have a calf per year, usually cows will be able to breed and produce calves until they are 7-10 years of age.
Freisian cows breed just like any other cows do. See the related question below.
Because they can produce more calves in one breeding season than a cow can. One bull can breed up to 50 cows in a natural breeding setting; in a laboratory environment, his sperm can breed many more ovums taken from different cows!!
An Elite cow is any cow from any breed that excels in production and progeny. These are usually diary cows, that produce high amounts of milk and give birth to heifers that do the same.
