u Nutrition is the science that deals with the use of food and the processes that change food into body tissues and energy.
u Horses need to use feed stuffs to convert into products such as milk, offspring, and work.
Digestible Nutrient u Portion of a nutrient which may be broken down (digested) and absorbed for use in the body.
Protein Carbohydrates Fats Minerals Vitamins Water Air
u Needed throughout life for growth and repair. u Help to form muscles, internal organs, skin, hair, and hoofs. u Contain carbon, hydrogen, oxygen and nitrogen.
Examples of Protein: u Meat and Bone Meal u Fish Meal u Soybean Meal u High quality alfalfa u Dried skim milk u Amino Acids
Carbohydrates: u furnish energy. u are the largest part of food supply, usually the fibrous part of the diet. u include sugars, starch, and cellulose.
u Furnish a concentrated source of energy, up to 2.25 times as much as carbohydrates. u Form cholesterol, steroids, and other body compounds. u Affect the condition of the skin and hair. u Are made of carbon, oxygen and hydrogen. u Also provide energy reserves, protection of vital organs, and insulation of the body
u Primarily in bones and teeth u Important in blood for carrying of oxygen u Regulates heartbeat with Calcium, Sodium, and Potassium.
Vitamins u Only needed in small amounts u Provide defense against disease u Promote growth and reproduction u Contribute to overall health
Water u Water accounts for 70% or more of the composition of most plants and animals.
Feed Classification u Roughages u Concentrates u Supplements
u High in fiber, relatively low in digestible nutrients. u Alfalfa u Clover u Soybeans u Oat Hay u Corn Silage
u Feeds that are low in fiber and relatively high in digestible nutrients. u Corn u Barley u Oats u Sorghum
u These are the “extras” that supply some necessary nutrient. u Minerals: salt, copper, iodine, iron, manganese, selenium, and zinc are examples. u Vitamins: A and D are most important to ruminant animals.
What is nutrition? The utilization of food to be converted into meat, milk, eggs, fiber and work What are the 6 nutrients needed? Protein, Carbohydrates, Fats, Minerals, Vitamins and Water. What are the 3 classifications of feed? Roughages, Concentrates and Supplements. Review…
The Digestive Tract u Horses are non-ruminant herbivores u Horses are able to utilize large amounts of roughage due to their relatively large cecum u Cecum is a section of the colon where digestive bacteria break down roughage
Digestive Tract u The Mouth- first part of digestive system. u Mouth has 2 main functions- masticate food and wet food with saliva.
Digestive tract cont. u Teeth should be examined by professional periodically to check for sharp edges that must be floated or filed down
Digestive tract cont. u The esophagus- 50- 60 inches long in an adult horse. u Esophagus will not allow vomiting. u Stomach may actually rupture before animal will vomit.
Digestive tract cont. u The Stomach- relatively small. Therefore horses should be fed several small meals per day. u The Small Intestine- contains 30% of the capacity of the entire tract. Food in the small intestine is 93-95% liquid. Nutrients are absorbed here.
Digestive tract cont. u The large intestine- 25 feet long, divided into cecum, colon and rectum
