Cell biology explains the structure, organization of the organelles they contain, their physiological properties, metabolic processes, signaling pathways, life cycle, and interactions with their environment. This is done both on a microscopic and molecular level as it encompasses prokaryotic cells and eukaryotic cells.
Small Intestine. Digesta passes from the stomach into the small intestine. The small intestine is approximately 28% of the horsesâ digestive tract, is 15-22m long and has a volume of 55-70 litres. This is the major site of digestion in the modern performance horse.f the horse is fasted, it will take 24 hours for the stomach to clear. It has long been a question as to what you should feed a horse first, grain or hay. Because of their density, grains tend to stay in the stomach longer, but it has not been proved to be advantageous to feed either first.
The equine digestive system is designed to extract nutrients from grass. Horses need long-stem fiber to remain healthy - in a perfect situation horses will graze for approximately 18 hours per day. What if the horse owner does not have good pasture? One of the options is to feed hay. (Other options are available, but thats another column.) Hay is made from grass, legumes or cereal crops that have been mowed, cured and baled. The type of vegetation from which hay has been made can vary based on location, availability and preference of the horse owner.
