Animal feed refers to the food given to domesticated animals, such as livestock and pets, to provide them with the necessary nutrients for growth, reproduction, and overall health. It can come in various forms, including grains, pellets, and forage, and is specifically formulated to meet the dietary needs of different species, such as cattle, poultry, and dogs. The composition of animal feed often includes proteins, carbohydrates, vitamins, and minerals. Farmers and pet owners choose specific types of feed based on the age, size, and health requirements of the animals. Proper nutrition is essential for ensuring the well-being and productivity of animals in agriculture and companionship.
