Cows are very heavy animals, they are most important for their
                        meat and their dairy products.
                            Cows usually has horns, Farmers remove them so they can't
                        injure someone. Different cows don't grow horns, they are called
                        polled cattle. Female cattle have large udders ( this is caused by
                        the milk). Their weight range from 700p - 2,000p. The largest
                        would be the bull (adult) male).

                                                        Breeds Of Cows
                            Cows were wild back a 1000 yr.. ago. Different cows mate
                          with each other, therefore they make new breeds.

                                                         Baby Cows
                           Heifer- Young female cows.
                          Cows live up to be about  20 years old until they die. This is
                           a long time for an animal's life span.  Sometimes the mother
                           would have twins, this isn't very likely but it could happen.
                           A cow has a calf when it is about 2 years old and  would have
                            a babyabout once a year.

                                Most Female dairy cows are raised until they die, but the
                         male's are sometimessold for their meat, this  is known as  "veal".
                                 Steer-  Are males that cannot produce.
                          Male cows cannot mates with the female, But they are very
                          active and most of the time they graze and rest.
                       This is all of the information that I found and I hope that it is
                              useful to you.
