Cattle

Cattle, colloquially referred to as cows, are disciplined ungulates, a member of the subfamily Bovina of the family Bovidae. They are raised as livestock for meat dairy products (milk), leather and as draught animals. In some countries, such as India, they are honored in religious ceremonies and revered. It is expected that there are 1.4 billion head of cattle in the world today.
Cattle were originally known by Carolus Linnaeus as three separate species. These were Bos taurus, the European cattle, including similar types from Africa and Asia, Bos indicus, the zebu,and the extinct Bos primigenius, the aurochs. The aurochs is ancestral to together zebu and European cattle. More newly these three have increasingly been grouped as one species, sometimes using the names Bos primigenius taurus, Bos primigenius indicus and Bos primigenius. Complicating the matter is the capacity of cattle to interbreed with other closely related species. Hybrid individuals and even breeds exist, not only between European cattle and zebu but also with yaks, banteng, gaur, and bison, a cross-genera fusion. Cattle cannot effectively be bred with water buffalo or African buffalo

Safety

Safety is the state of being safe, the situation of being protected against physical, social, spiritual, financial, political, emotional, occupational, psychological, educational or additional types or consequences of failure, damage, error, accidents, harm or any other event which could be considered non-desirable. This can take the form of being protected from the event or from exposure to something that causes health or reasonable losses. There also are two slightly different meanings of safety, a safety home may indicate its protection ability against external harm events, and the second that its internal installations are safe for its habitants.
Safety can be limited in relative to some guarantee or a standard of insurance to the quality and unharmful function of an object or organization. It is used in order to ensure that the object or association will do only what it is meant to do. Normative safety is a term used to explain products or designs that meet applicable design standards. Substantive safety stands for that the real-world safety history is favorable, whether or not standards are met. Perceived safety refers to the stage of comfort of users

Hockey

Hockey is any of a family of sports in which two teams struggle by trying to maneuver a ball, or a hard, surrounding disc called a puck, into the opponent's net or goal, using a hockey stick. Field hockey is played on nettle, natural grass, sand-based or water-based artificial turfs, with a small, hard ball. The game is popular among both males and females in many countries of the world, mostly in Europe, India, Pakistan, Australia, New Zealand, South Africa and South Asia. In most countries, the game is played between single-sex sides, even though it can be played by mixed-sex sides. In the United States and Canada it is played mostly by women.Ball hockey is played in a gym using sticks and a ball, often a tennis ball with the hair removed.

There are early representations and reports of hockey-type games being played on ice in the Netherlands, and reports from Canada from the beginning of the nineteenth century, but the modern game was initially planned by students at McGill University, Montreal in 1875 who, by two years later, codified the first set of ice hockey rules and organized the first teams.
