Cows are cattle familia members Bovidae and subfamilia Bovinae. Cattle kept primarily for milk and meat used as food. The byproduct, such as skin, viscera, and then used its horns as well. In some places, cattle are also used to help grow crops, such as pulling carts or plows.
Holstein cow or Frisian is one breed of dairy cow known today as the largest cattle producing milk. Originating from Europe, bred holstein cow in an area that is now the province of North Holland and Friesland, Netherlands (so not from Holstein, Germany). Large holstein cow with spotted black and white on his body. In a narrow sense, holstein cow has black ears, white feet and a white tail tip. FH type cattle in Indonesia can produce milk 20Liter/hari, but the average production 3.050Kg 10Liter/hari or lactation milk 1 times. This type of FH bulls can reach 1,000 kg weight, and ideal body weight is 635 kg females. FH kind of American beef can produce more than 7,000 kg of milk in one lactation time.
also facilitate a rapid physical response. A long, fluid, greyhound-like
body is streamlined over light bones. Small collarbones and vertical shoulder
blades help lengthen the stride. 
nocturnal predators, the cheetah is primarily
diurnal, hunting in early morning and late afternoon. Since it depends on
sight rather than smell, it likes to scan the countryside from a tree limb
or the top of a termite mound. Other big cats chase only a few hundred meters:
the cheetah chases 3.4 miles (5500 meters) at an average speed of 45 miles
per hour (72 kilometers per hour). Stalking is as important as the fast
sprint: usually it will creep within 50 yards (46 meters) of an intended
victim before the final acceleration. Full sprints last about 20 seconds
and almost never exceed 1 full minute. If it succeeds in catching an animal
the cheetah will suffocate it by clamping the animal's windpipe, sometimes
holding a clamp as long as 5 minutes. Very small animals like hares are
killed by a simple bite through the skull. But whatever the meal - large
or small - cheetah eats quickly for if challenged it will most often
lose. Cheetahs have unusually clean eating habits: they do not return to
their kill nor do they eat carrion; they leave the skin, bones and entrails
of their prey. At 6 weeks the young are strong enough to follow the hunt
and when they are about 6 months old the mother will capture live prey for
them to practice killing.
