Term
Nutrition
Definition
The processes by which an animal takes in and makes use of (assimilates) feed components in order to carry out life processes, i.e. maintenance, growth, production, reproduction, and work.
Term
Nutrient
Definition
Any food component, chemical, or constituent that aids in life processes.
Term
List nutrients:
Definition
Water Carbohydrates Lipids Proteins Vitamins Minerals
Term
Essential Nutrient
Definition
A nutrient that must be taken in through the diet.
Term
Why must essential nutrients be gained through the diet?
Definition
The body is unable to produce them, or produce enough of them.
Term
Non-Essential Nutrient
Definition
A nutrient that the body can synthesize on its own, or nearly enough of on its own.
Term
Macronutrient
Definition
A nutrient that is required in relatively large amounts.
Term
List macronutrients:
Definition
Water
Lipids
Proteins
Carbohydrates
Term
Micronutrient
Definition
A nutrient that is required in very small amounts.
Term
List micronutrients:
Definition
Vitamins
Minerals
Term
Upon what does nutrient utilization depend?
Definition
Ingestion
Digestion and Fermentation
Absorption
Metabolism
Term
In what animal was insulin discovered?
Definition
Dog
Term
Non-ruminant
Definition
Simple stomach
Term
List examples of non-ruminant animals:
Definition
Poultry, swine, fish, pets, horses
Term
Ruminant
Definition
Multi-compartmental stomach
Term
List examples of ruminant animals:
Definition
Sheep, goats, cattle (dairy and beef)
Term
In what form do plants use N?
Definition
Nitrate and ammonia
Term
What do plants synthesize using N?
Definition
Amino acids and proteins
Term
From where do plants get their nutrients?
Definition
The soil.
Term
From where do animals get their N?
Definition
Amino acids
Term
From where do animals get their fat?
Definition
Fatty acids, essential mineral elements, vitamins, and source of energy
Term
Feeds or Feedstuffs
Definition
Any material included in an animal's diet or ration because of its nutritional value.
Term
List types of feeds:
Definition
Cereal grains
By-product feeds
Forages and roughages
Protein feeds
Mineral supplements
Vitamin supplements
Feed additives
Term
What is a feed additive?
Definition
Medication that has no (or very very little) nutritional value
Term
Ration or Diet
Definition
24-hour allowance of feed or mixture of feed ingredients.
Term
Can a feed be assumed to be nutritionally adequate?
Definition
No. There is no one feed that is nutritionally balanced.
Term
Balanced ration or diet
Definition
A ration or diet that is implied to be nutritionally adequate to meet an animal's nutritional needs for a specific purpose.
Term
Why are large amounts of feed required?
Definition
To maintain weight. Even larger amounts are required to gain weight or increase production.
Term
Insufficient nutrient intake results in what?
Definition
Decrease in production, starvation, and possible death.
Term
Excessive nutrient intake results in what?
Definition
Increase in environmental pollution.
Term
Excessive carbohydrate consumption results in what type of pollution?
Definition
GHG - greenhouse gas - CH4: Methane - in cattle especially
Term
Excessive N consumption results in what type of pollution?
Definition
NH3 - Ammonia
N2O - Nitrous Oxide
Term
What is the most expensive feed type?
Definition
Protein feeds
Term
Do animals have a specific feed requirement?
Definition
No. The actual feed is less important than the quantity and assortment of nutrients that the feed supplies.
Term
What is the carrier of nutrients?
Definition
Feed
Term
Is there any one feed considered nutritionally adequate?
Definition
No
Term
What type of toxic components can feeds contain?
Definition
Molds and mycotoxins
Term
What causes toxic components to grow on feed?
Definition
Improper feed storage
Term
What are the major functions of nutrients?
Definition
Energy
Synthesis of tissue constituents
Cofactors for metabolic reactions
Regulation of body functions
Term
What are the three main sources of energy?
Definition
Carbohydrates
Protein
Lipids
Term
How much energy can be gained from carbohydrates?
Definition
4 kcal/g
Term
How much energy can be gained from protein?
Definition
5 kcal/g BUT tissues only receive 4 kcal/g - due to urea synthesis
Term
Energy is used for:
Definition
Maintenance
Tissue growth
Production
Storage
Term
Feed efficiency
Definition
Economic benefits vs nutrient benefits.
Feed ratio of gain and production
Term
Catabolize
Definition
An amino acid having its carbon broken down for energy
Term
Carbohydrates are converted to what for storage?
Definition
Lipids
Term
Glucose is stored as what?
Definition
Temporarily as glycogen, then later broken down to lipids
