Feed
Feed (/fi:d/), from the Old English fēdan, is a term used in the medical and veterinary fields to refer to the provision of nutrients to both humans and animals. It is a crucial aspect of nutrition and healthcare, as it directly impacts the overall health and well-being of the individual or animal.
Etymology
The term "feed" originates from the Old English fēdan, which means to nourish or sustain. It has been used in the English language since the 9th century and has since evolved to encompass a wide range of meanings in various fields.
Medical Usage
In the medical field, "feed" is often used to refer to the process of providing nutrients to patients who are unable to eat normally. This can be done through various methods, such as enteral feeding, where nutrients are provided directly to the stomach or small intestine, or parenteral feeding, where nutrients are provided intravenously.
Veterinary Usage
In veterinary medicine, "feed" refers to the food given to animals, particularly livestock. The quality and type of feed can significantly impact the health and productivity of the animals. Various types of feed include forage, which is plant material (mainly plant leaves and stems) eaten by grazing livestock, and concentrate, which is a dense form of feed that is high in energy.
