Cow welfare

Cow welfare

The term "animal welfare" was coined by American Hughes in 1976 to refer to the state of complete mental and physical health of animals raised on farms in harmony with their environment. It is generally believed that animal welfare refers to the external conditions for the protection of animal well-being, that is, the conditions given to animals by humans to meet their well-being. Internationally, the concept of animal welfare has been widely understood as freedom from hunger and thirst, freedom to live comfortably, freedom from pain, injury and disease, freedom to live without fear and sadness, and freedom to express nature. These five freedoms, in turn, are broadly summarized as the five key elements of animal welfare protection.
