In animal farming, a concentrated animal feeding operation (CAFO), as defined by the United States Department of Agriculture (USDA), is a type of intensive animal feeding operation (AFO) where more than 1,000 animal units are kept in confinement for more than 45 days each year. An animal unit equals 1,000 pounds of live animal weight. For example, 1,000 animal units could be 700 dairy cows, 1,000 meat cows, 2,500 pigs weighing more than 55 pounds, 10,000 pigs weighing less than 55 pounds, 10,000 sheep, 55,000 turkeys, 125,000 chickens, or 82,000 egg-laying hens or pullets.
Intensive animal farming, also called factory farming, is a method used by the meat and dairy industry to produce large amounts of animal products, such as meat, milk, and eggs, while keeping costs low. To do this, large farms raise animals like cows, chickens, and fish in very high numbers, using modern machines, technology, and medicines. These farms focus on efficiency and scale to meet the demand for food.
Industrial agriculture is a type of modern farming that involves the large-scale production of crops and animal products such as eggs and milk. Methods used in industrial agriculture include advances in farming equipment and techniques, genetic technology, producing large amounts of goods efficiently, creating new markets for food, protecting genetic information with patents, and participating in global trade. These practices are common in developed countries and are becoming more widespread around the world.
High-yielding varieties (HYVs) of agricultural crops are types of crops that have certain features different from traditional crops. These features include the ability to produce more food from the same amount of land. Some of the most common HYVs include wheat, corn, soybean, rice, potato, and cotton.
The Green Revolution, also known as the Third Agricultural Revolution, was a time when new farming technologies were shared widely, leading to much higher crop production. These changes first began in developed countries in the early 1900s and later spread around the world until the late 1980s. In the late 1960s, farmers started using new tools and methods, such as high-yielding cereal plants like dwarf wheat and rice, chemical fertilizers (which are needed in much larger amounts than older plant varieties), pesticides, and controlled water systems for crops.
A Vavilov center, also called a center of origin, is a place where certain plants or animals first developed their unique characteristics. In 1924, a scientist named Nikolai Vavilov identified these centers. He believed that the center of origin for a species is the same place where it has the most genetic variety.
A Vavilov center, also called a center of origin, is a place where a group of living things, whether grown by people or found in nature, first developed their unique traits. These centers were first discovered in 1924 by a scientist named Nikolai Vavilov. Vavilov believed that the center of origin for a species or group of species is the same as its center of diversity, which is the area where that species has the most variety of genetic traits.
A crop wild relative (CWR) is a wild plant that is closely connected to a plant that people grow. It could be the wild ancestor of the grown plant or a different type of plant that is closely related.
A seed bank, also called a seed vault, stores seeds to keep different types of plant genes safe. This makes it a type of gene bank. There are many reasons to store seeds.
Plant breeding is the process of changing plant traits to create desired features. It helps improve the quality of plants so they can be used by people and animals. The goal is to develop crops with special traits that are useful for many purposes.
