Carbohydrates
Vitamins

What are the feed classifications?
Forages

Concentrations
Additives
What are Forages?
Can be moisture forages such as pasture or can be dried as hay. Silage (pasture grass that has been fermented) is also a forage.
Tend to have a high nutritive value.
What are Roughages?
Roughages are usually straw as well as grass or legumes with greater fiber content.
Have higher fiber content, low digestability
What are Concentrations?
Concentrated sources of energy or protein.
Energy- Brewery byproducts, cereal, grains, animal and vegetable fats, beet pulp, fruits, bakery waste.
Protein- Include seeds, oilseed, meals (soybean, cottonseed, linseed), animal/poultry by products, non protein nitrogen, dried distillers/brewer grains.

Vitamin/Mineral additives
Non-nutritive additives: Flavors, Medicine etc.
What is Ration?

(Diet)
Adjusted for, growth, maintenance, finishing, production/work, pregnancy, lactation
Where does digestion begin?
In the mouth
What type of digestion occurs in the mouth and by what?
Mechanical- Teeth when chewing to reduce particle size
Saliva- Role in buffering the gut and has amylase
What is Monogastric?
Animals have 1 compartment in their stomach
What is Monogastric Hindgut fermenters and which animals?
Have a large cecum that allows to ferment food usually low in cellulose
Horse and Bunnies
What is Ruminant?
Animals that have 4 compartment in their stomach
What are the 4 parts of a Ruminant stomach?
Rumen
Reticulum
Omasum
Abomasum
What is the rumen’s role?
Where food gets fermented by breakdown of cellulose due to bacteria
What is the abomasum’s role
“The true stomach” it has the acid
