Nutrition is the science that deals with the use of food and the processes that change food into body tissues and energy.

Page 3: Katy Hoag Cal Poly AgEd410 u Nutrition is the science that deals with the use of food and the processes that change food into body tissues and energy.

Horses need to use feed stuffs to convert into products such as milk, offspring, and work.

Digestible Nutrient Portion of a nutrient

which may be broken down (digested) and absorbed for use in the body.

Needed throughout life for growth and repair.

Help to form muscles, internal organs, skin, hair, and hoofs.

Contain carbon, hydrogen, oxygen and nitrogen.

Examples of Protein: Meat and Bone Meal Fish Meal Soybean Meal High quality alfalfa Dried skim milk Amino Acids

Page 8: Katy Hoag Cal Poly AgEd410 u Nutrition is the science that deals with the use of food and the processes that change food into body tissues and energy.

Carbohydrates: furnish energy. are the largest part of food supply, usually

the fibrous part of the diet. include sugars, starch, and cellulose.

Page 9: Katy Hoag Cal Poly AgEd410 u Nutrition is the science that deals with the use of food and the processes that change food into body tissues and energy.

Furnish a concentrated source of energy, up to 2.25 times as much as carbohydrates.

Form cholesterol, steroids, and other body compounds.

Affect the condition of the skin and hair. Are made of carbon, oxygen and hydrogen. Also provide energy reserves, protection of vital

organs, and insulation of the body

Primarily in bones and teeth Important in blood for carrying of oxygen Regulates heartbeat with Calcium, Sodium, and

Potassium.

Vitamins Only needed in small amounts Provide defense against disease Promote growth and reproduction Contribute to overall health

High in fiber, relatively low in digestible nutrients.

These are the “extras” that supply some necessary nutrient.

Minerals: salt, copper, iodine, iron, manganese, selenium, and zinc are examples.

Vitamins: A and D are most important to ruminant animals.

Digestive Physiology of the Horse

Page 19: Katy Hoag Cal Poly AgEd410 u Nutrition is the science that deals with the use of food and the processes that change food into body tissues and energy.

The Digestive Tract Horses are non-ruminant herbivores Horses are able to utilize large amounts of

roughage due to their relatively large cecum Cecum is a section of the colon where

digestive bacteria break down roughage

Page 20: Katy Hoag Cal Poly AgEd410 u Nutrition is the science that deals with the use of food and the processes that change food into body tissues and energy.

Digestive Tract The Mouth- first part

of digestive system. Mouth has 2 main

functions- masticate food and wet food with saliva.

Page 21: Katy Hoag Cal Poly AgEd410 u Nutrition is the science that deals with the use of food and the processes that change food into body tissues and energy.

Digestive tract cont. Teeth should be

examined by professional periodically to check for sharp edges that must be floated or filed down

Page 22: Katy Hoag Cal Poly AgEd410 u Nutrition is the science that deals with the use of food and the processes that change food into body tissues and energy.

Digestive tract cont. The esophagus- 50- 60 inches long in an

adult horse. Esophagus will not allow vomiting. Stomach may actually rupture before

animal will vomit.

Page 23: Katy Hoag Cal Poly AgEd410 u Nutrition is the science that deals with the use of food and the processes that change food into body tissues and energy.

Digestive tract cont. The Stomach- relatively small. Therefore

horses should be fed several small meals per day.

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.

Page 24: Katy Hoag Cal Poly AgEd410 u Nutrition is the science that deals with the use of food and the processes that change food into body tissues and energy.

Digestive tract cont. The large intestine- 25 feet long, divided

into cecum, colon and rectum

Page 25: Katy Hoag Cal Poly AgEd410 u Nutrition is the science that deals with the use of food and the processes that change food into body tissues and energy.
Page 26: Katy Hoag Cal Poly AgEd410 u Nutrition is the science that deals with the use of food and the processes that change food into body tissues and energy.

Rate of passage 95% of all food eaten will be excreted in the

form of feces within 65-75 hours of ingestion

Page 27: Katy Hoag Cal Poly AgEd410 u Nutrition is the science that deals with the use of food and the processes that change food into body tissues and energy.

Site of Digestion Protein, Carbohydrates,fat, minerals and

vitamins are all digested in the small intestine

Water is absorbed in the large intestine

Page 28: Katy Hoag Cal Poly AgEd410 u Nutrition is the science that deals with the use of food and the processes that change food into body tissues and energy.

Factors Affecting Digestion Processing of feeds-

pellets require less digestion than whole grains.

Page 29: Katy Hoag Cal Poly AgEd410 u Nutrition is the science that deals with the use of food and the processes that change food into body tissues and energy.

Feed processing Grinding feed speeds

digestion

Page 30: Katy Hoag Cal Poly AgEd410 u Nutrition is the science that deals with the use of food and the processes that change food into body tissues and energy.

Feed Processing Crimping oats will

increase rate of digestion.

Page 31: Katy Hoag Cal Poly AgEd410 u Nutrition is the science that deals with the use of food and the processes that change food into body tissues and energy.

Factors affecting Digestion cont. Level of intake- the more grain eaten, the

less digested Frequency of feeding- frequent feeding can

increase level of digestion.

Page 32: Katy Hoag Cal Poly AgEd410 u Nutrition is the science that deals with the use of food and the processes that change food into body tissues and energy.

Factors cont. Work- light work

increases digestion, heavy work inhibits it.
