DRAMIŃSKI - Cow mastitis

The world cattle population is estimated to be about 1.3 billion head. India is the nation with the largest number of cattle, about 400 million, followed by Brazil and China, with about 150 million each, and the United States, with about 100 million. Africa has about 200 million head of cattle, many of which are herded in traditional ways and serve partly as tokens of their owner’s wealth. Europe has about 130 million head of cattle (CT 2006, SC 2006).

Cattle today are the basis of a multi-billion dollar industry worldwide. The international trade in beef for 2000 was over $30 billion and represented only 23 percent of world beef production. (Clay 2004). The production of milk, which is also made into cheese, butter, yogurt, and other dairy products, is comparable in economic size to beef production and provides an important part of the food supply for many of the world’s people. Cattle hides, used for leather to make shoes and clothing, are another widespread product. Cattle remain broadly used as draft animals in many developing countries, such as India.
