Dry Matter? - 🧠ANSWER ✔✔- Is a fundamental concept in animal
agriculture
- Non-water component of feed/food
- "solids"
- Is the economic aspect of animal nutrition
Dry Weight? - 🧠ANSWER ✔✔Weight of food/feed stuff when completely
dried
What is the difference between dry matter and as fed? - 🧠ANSWER ✔✔DM
- feed without water (what Ag buys)

,NOTE: the % chances but the g of nutrients does not change
Why is it important to put things on DM basis? - 🧠ANSWER ✔✔Cost and
Nutrient Value
___g = 1 Ib - 🧠ANSWER ✔✔454 g = 1 Ib
1 ton = ___kg - 🧠ANSWER ✔✔1 ton = 908 kg
What is occurs during fermentation? - 🧠ANSWER ✔✔Microorganisms +
Glucose = VFA/Lactate/Alcohol + CO₂
Where does fermentation occur? What are some types of
fermentation(examples)? - 🧠ANSWER ✔✔In a close environment where
there is no supply of oxygen and open environments where oxygen is
plentiful
Some Types:
- Rumen and hindgut fermentation - via microorganisms
- Alcohol fermentation - via microorganisms
- Lactic acid fermentation - in oxygen deprived muscles

,- Bread making - via microorganisms
Fermentation? - 🧠ANSWER ✔✔Process of transforming carbohydrates into
alcohol and CO₂ or organic acids through yeast, bacteria, or a combination
of the two
Calories? - 🧠ANSWER ✔✔Measure of fuel you get from the food you eat
Energy (people need about 2,000/day)
Gluten? - 🧠ANSWER ✔✔Protein in some grains
Lactose? - 🧠ANSWER ✔✔Sugar, no lactose in most solid cheese
Flatulence? - 🧠ANSWER ✔✔Demonstrates fermentation is occurring, gas
What is the basic path of feed to waste through the body? - 🧠ANSWER
✔✔Feeds -digestion-> Nutrients -Absorption-> Tissues
Tissues -metabolism-> Metabolites -excretion-> waste
↓
→Maintenance, Repro, Neonate, Growth, Lactation, Work
Do plants, dairy farmers, and dairy cows all have the same goals? -
🧠ANSWER ✔✔NO

, - Plant Goals: reach repro maturity, develop & protect viable seeds, not to
be consumed by a ruminant
- Dairy Farmer Goals: harvest highest quality, harvest adequate tonnage
- Dairy Cow Goals: extract energy from starch and fiber
Every part in the system has a different goal
What are the types of carbohydrates? - 🧠ANSWER ✔✔Non-structural
Carbs
Structural Carbs
Carbohydrates? - 🧠ANSWER ✔✔Organic compound with CHO in it
Non-structural Carbohydrates? - 🧠ANSWER ✔✔Soluble sugars and pectin
- very digestible
Structural Carbohydrates? - 🧠ANSWER ✔✔Fiber, usually discussed when
talking about ruminants
Cellulose, hemicellulose, lignin
- gives plant structure(seen in stem), less digestible
