Nutrition - CORRECT ANSWER -
series of processes in which food or feed is taken in and absorbed into the body of an organis
m which serves for purpose of: growth, work, maintenance, and repair of vital processes.
Feedstuff - CORRECT ANSWER -
edible material consumed by animals which contributes energy and/or nutrients
18th century - CORRECT ANSWER -little levosa--father of nutrition
19th century - CORRECT ANSWER -
better understanding of fats, protein(provide amino acids and expensive), carbohydrates (used
for energy)
20th century - CORRECT ANSWER -vitamins and minerals (still not a lot of info)
Energy - CORRECT ANSWER -
heat: forcefulness of the body to drive various physiological processes
Nutrients - CORRECT ANSWER -
feed constituent or group of feed constituents that aid in the support of life
ration - CORRECT ANSWER -an amount of feed consumed by an animal in 24 hours
balanced ration - CORRECT ANSWER -
one which provides an animal the proper amount and proportions of all the required nutrients
for 24 hours
,Diet - CORRECT ANSWER -
balanced mixture of feedstuffs which nourish the animal for more than 24 hours
Water - CORRECT ANSWER -=>simplist form=>absorbed in the blood
Carbs - CORRECT ANSWER -=>glucose or simple sugar==>blood
Lipid - CORRECT ANSWER -=>emulsify=>lymph system
Feedstuff components - CORRECT ANSWER -
water, dry matter (inorganic material=minerals), organic material like nitrogenous material (pro
tein or npn example is urea), lipids (simple, compound, pseudo), carbohydrates (fiber, Nitrogen
free extract=easy to digest)
Daily dry matter consumed by animals expressed as percent of BW or body weight -
CORRECT ANSWER -Poultry 5-6%
Swine 4-5%
Sheep 3-4%
Cattle 2-3%
Horses 1.5-2.5%
*May change but not too much
Regulatory - CORRECT ANSWER -water, minerals, vitamins, proteins
Ex. digestion, heart rate, respiration
structural - CORRECT ANSWER -minerals, proteins, fats
ex. bones, muscle, tendons
,Energy - CORRECT ANSWER -protein, fat, carbohydrates
ex. lactating
Natural sources - CORRECT ANSWER -Sun-energy-vitamin D
Soil-minerals and chemicals-graze animals
Air-C, N, O, H
Photosynthesis - CORRECT ANSWER -CO2 + H20 Sunlight/Plants glucose + O2
Various metabolic pathways in the body - CORRECT ANSWER -
can synthesize lipids and/or proteins
Plants have more carbohydrates than a steer because - CORRECT ANSWER -of photosynthesis
Steers have less carbohydrates because it is used for - CORRECT ANSWER -energy
Water - CORRECT ANSWER -cheapest and most abundant nutrient
Most important and the most overlooked
65-85% of BW is water at Birth
45-60% at maturity
90-95% of blood is water
79-90% tissue
intracellular=in skin, muscle
extracellular=muscle
urinary and GI tract
, Water consumption - CORRECT ANSWER -
dairy cattle need 2 gallons more on average than beef cattle due to lactation. Weather, fiber, a
nd etc can change this (more fiber = more water, more heat = more water)
Water Function - CORRECT ANSWER -1. nutrient/waste transport (cardiovascular),
2. metabolic/chemical reaction
3. aids digestion/absorption
4. regulate body temperature
5. regulate ionic concentrations
6. body structural components
7. lubricates and cushions
Water Deficiencies or Restrictions - CORRECT ANSWER --reduced feed consumption
-weight loss
- increased excretion of nitrogen and electrolytes (sodium and potassium)
-death
Water Sources: Drinking - CORRECT ANSWER -Factors affecting consumption:
1. DM consumption (more eat=more water)
2. Dietary Factors
3. Environment
4. Access to H20
5. type of urinary system
6. function of animal
7. water quality
